How To connect HD Multi Room TV, 1 source to 4 TVs using HDMI Splitters / Amplifiers
Hi, this video shows you how to connect up a Virginmedia Set Top Box and a ROKU 2 XS media player (you can use Apple TV, Blu-Ray, DVD etc.) to 4 TVs using 2 HDMI splitters. The HDMI splitters have 1 input to 4 outputs so 4 TVs can simultaneously show the same display. This is ideal if you want the flexibility to watch your equipment in any room. The HDMI Splitters transmit full HD (1080p) so there is no loss of quality. The video also shows an IR (infrared) Kit to transmit the Virginmeida Rmeote control to all 4 TVs. The Roku 2XS uses Bluetooth which struggles to transmit outside the under stairs cupboard so I use the Android and Apple App for the Roku remote control which uses WiFi to allow you to control the Roku and it works really well. The down side of this install apart from the time and money spent on the installation is that you have to watch the same thing on all 4 TVs. Many thanks Vince

MHL-enabled products include adapters, automotive accessories, AV receivers, Blu-ray Disc players, cables, DTVs, media sticks, monitors, projectors, smartphones, tablets, TV accessories and more. MHL is a consortium made up of major companies in the mobile and CE industries, including Nokia, Samsung, Silicon Image, Sony and Toshiba. MHL was originally intended for mobile devices such as smartphones and tablets. High-definition video and eight-channel surround sound.Encrypted video and audio via High-bandwidth Digital Content Protection (HDCP).Transition Minimized Differential Signaling (TMDS) for video, audio, and auxiliary data.5-volt DC power on the cable.HDMI-CEC control of remote devices. To better accommodate the needs of mobile devices, MHL differs from HDMI as follows. Five wires in place of HDMI's nineteen, namely ground, power, control, and a differential pair for data. This permits a much lighter cable and a much smaller connector on the mobile device.Whereas HDMI uses the power line to provide 5 volts from the source at 50 mA (0.25 W) for the purpose of awakening a sleeping sink, MHL uses it to provide that voltage from the sink at 900 mA (4.5 W) to maintain the state of charge of the source. This allows a mobile device with only one port for both charging and MHL to operate indefinitely without exhausting the battery, provided 4.5 W is sufficient. Devices needing more power from the port used for MHL may not be suitable candidates for MHL 2.0; MHL 3.0 raises the power requirement to 2 A (10 W).Although MHL ports can be dedicated to MHL alone, the standard is designed to permit port sharing with the most commonly used ports.A typical MHL source will be shared with USB 2.0 on a standard 5-pin micro-usb receptacle, which switches from USB to MHL when it recognizes an MHL-qualified sink detected on the control wire.A typical MHL sink will be shared with HDMI on a standard 19-pin HDMI receptacle. The standard uses the same pins for power (pin 18) and ground (pins 5, 11, and 17), HDMI's Hot Plug detect (pin 19) for MHL control, and HDMI's Data0 channel (pins 7 and 9) for MHL's data.Whereas HDMI transmits the three bytes of a pixel in parallel over three physically separate differential pairs along with a fourth pair for a clock, with a separate ground for each pair (pins 1-12), MHL transmits them sequentially over one pair (7 and 9), with the clock added in as a common mode signal to the differential signal. The receiver then has both differential and common mode detection circuits.[10] In MHL 3 and superMHL the clock signal is instead carried separately on an extended CBUS, renamed the enhanced control bus (eCBUS).Whereas HDMI uses three wires to cater for HDMI-CEC (13), and DDC (15 and 16), MHL controls these functions with a single wire (CBUS).In normal mode MHL supplies the same 24 bit color signal as HDMI, at a pixel clock rate of up to 75 MHz for MHL 2.0, sufficient for 1080i and 720p. Each of the three bytes is in a 10-bit frame whence at 75 MHz the data channel operates at 2.25 Gbit/s.[11][12]MHL 2.0 caters for 1080p with a PackedPixel mode utilizing only the first two of HDMI's three channels. This shrinks each pixel to 16 bits (using YCbCr 4:2:2 chroma subsampling) carried in two 10-bit frames. The pixel clock is doubled to 150 MHz and the data channel then operates at 3 Gbit/s.[11][12]MHL's serial signaling makes it incompatible with the three-channel parallel signaling of HDMI and DVI. Hence both ends of an MHL channel must implement the standard in full. In particular an MHL source cannot drive an ordinary HDMI or DVI display, though this limitation is easily overcome with an MHL dongle converting MHL to HDMI. An MHL source must be realized in hardware as the typical 5-pin USB 2.0 port on mobile devices is much too slow at 480 Mbit/s for a software-only implementation Social Media Business Links Gmail [email protected] FaceBook https://www.facebook.com/HappyLifePartsOfficial Twitter https://www.twitter.com/Asim5306 Instagram https://www.instagram.com/happy_life_parts/ Whatsapp (Just Click on Link) https://goo.gl/TgSEHG

How Radio Waves Are Produced
UNLOCKING THE MYSTERIES BEHIND RADIO WAVES. Electric current creates magnetic field, oscillating electric current creates oscillating magnetic field and not "electromagnetic wave" as current belief. Electron has a standing- electric field and magnetic field at right angle (watch video structure of electron). The flow of electrons in a conductor is essentially caused by the attraction between the electric fields of mobile electrons and "fixed" positive charges in the conductor. Oscillation of electrons in a conductor is caused by the alternation of electric polarity in the conductor. Because of electric field and magnetic field of an electron is at right angle, when oscillates the electric field of the electron will be parallel to the oscillation and magnetic field will be perpendicular to the oscillation.This oscillation of the electron creates transverse wave on its magnetic line and the oscillating magnetic line is radiated to space. http://www.amazon.com/author/atom http://www.facebook.com/novaphysica https://www.youtube.com/user/atommodel

Electromagnetic Spectrum: Radio Waves
http://www.facebook.com/ScienceReason ... [email protected]: EMS Electromagnetic Spectrum (Episode 2) - Radio Waves The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. The "electromagnetic spectrum" of an object is the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. --- Please SUBSCRIBE to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- MEASURING THE ELECTROMAGNETIC SPECTRUM The electromagnetic (EM) spectrum is just a name that scientists give a bunch of types of radiation when they want to talk about them as a group. Radiation is energy that travels and spreads out as it goes - visible light that comes from a lamp in your house and radio waves that come from a radio station are two types of electromagnetic radiation. Other examples of EM radiation are microwaves, infrared and ultraviolet light, X-rays and gamma-rays. Hotter, more energetic objects and events create higher energy radiation than cool objects. Only extremely hot objects or particles moving at very high velocities can create high-energy radiation like X-rays and gamma-rays. • http://imagine.gsfc.nasa.gov/docs/science/know_l1/emspectrum.html --- RADIO WAVES Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Like all other electromagnetic waves, they travel at the speed of light. Naturally-occurring radio waves are made by lightning, or by astronomical objects. Artificially-generated radio waves are used for fixed and mobile radio communication, broadcasting, radar and other navigation systems, satellite communication, computer networks and innumerable other applications. Different frequencies of radio waves have different propagation characteristics in the Earth's atmosphere; long waves may cover a part of the Earth very consistently, shorter waves can reflect off the ionosphere and travel around the world, and much shorter wavelengths bend or reflect very little and travel on a line of sight. Discovery and utilization: Radio waves were first predicted by mathematical work done in 1865 by James Clerk Maxwell. Maxwell noticed wavelike properties of light and similarities in electrical and magnetic observations. He then proposed equations, that described light waves and radio waves as waves of electromagnetism that travel in space. In 1887, Heinrich Hertz demonstrated the reality of Maxwell's electromagnetic waves by experimentally generating radio waves in his laboratory. Many inventions followed, making practical the use of radio waves to transfer information through space. Propagation: The study of electromagnetic phenomena such as reflection, refraction, polarization, diffraction and absorption is of critical importance in the study of how radio waves move in free space and over the surface of the Earth. Different frequencies experience different combinations of these phenomena in the Earth's atmosphere, making certain radio bands more useful for specific purposes than others. Radio communication: In order to receive radio signals, for instance from AM/FM radio stations, a radio antenna must be used. However, since the antenna will pick up thousands of radio signals at a time, a radio tuner is necessary to tune in to a particular frequency (or frequency range). This is typically done via a resonator (in its simplest form, a circuit with a capacitor and an inductor). The resonator is configured to resonate at a particular frequency (or frequency band), thus amplifying sine waves at that radio frequency, while ignoring other sine waves. Usually, either the inductor or the capacitor of the resonator is adjustable, allowing the user to change the frequency at which it resonates. In medicine: Radio frequency (RF) energy has been used in medical treatments for over 75 years generally for minimally invasive surgeries and coagulation, including the treatment of sleep apnea. • http://en.wikipedia.org/wiki/Radio_waves .

Basic VHF and UHF Fundamentals
Basic VHF and UHF Fundamentals Antennas are a very important component of communication systems. By definition, an antenna is a device used to transform an RF signal, traveling on a conductor, into an electromagnetic wave in free space. Antennas demonstrate a property known as reciprocity, which means that an antenna will maintain the same characteristics regardless if it is transmitting or receiving. Most antennas are resonant devices, which operate efficiently over a relatively narrow frequency band. An antenna must be tuned to the same frequency band of the radio system to which it is connected, otherwise the reception and the transmission will be impaired. When a signal is fed into an antenna, the antenna will emit radiation distributed in space in a certain way. A graphical representation of the relative distribution of the radiated power in space is called a radiation pattern.

My First Perfect ISS SSTV Image!
Subscribe for more vids! https://www.youtube.com/SpaceComms1?sub_confirmation=1 With 25 watts of power coming from the radio on the ISS, the signal, transmitted on 145.800 MHz, can be received with a setup as simple as a handheld amateur radio or scanner, and a rubber duck antenna. Decoding the images can be as simple as holding the radio next to the microphone of an iOS or Android device. Ideally though, you would use a high gain or directional antenna, and an audio cable connected directly between the radio and decoding device, whether it’s a smart phone or a computer. Whatever software you use, make sure it’s set to SSTV mode PD120, as that’s what the ISS will be using, and if you don’t set that, you might not decode any images at all (see hint below). = Recommended decoding software = For iOS use “CQ SSTV” https://itunes.apple.com/app/sstv/id387910013 For Android use “Robot36” https://play.google.com/store/apps/details?id=xdsopl.robot36&hl=en For Windows use “MMSSTV” (see AMSAT UK link below for setup) http://hamsoft.ca/pages/mmsstv.php For Mac OS X use “Multiscan 3B SSTV” (not verified) http://www.qsl.net/kd6cji/ = Tracking the ISS = Howto use heavens-above.com to track the ISS https://spacecomms.wordpress.com/howto-use-heavens-above-com-to-track-th... == Other ISS tracking methods == == Websites: == ISS Fan Club http://issfanclub.com/ ISSTracker (no predictions, just live tracking) http://www.isstracker.com/ Android: Heavens-Above https://play.google.com/store/apps/details?id=com.heavens_above.viewer ISS Dectector Satellite Tracker https://play.google.com/store/apps/details?id=com.runar.issdetector iOS: Space Station (ISS) (not verified) https://itunes.apple.com/us/app/space-station-iss/id301984767?mt=8 = What to expect during a pass = SSTV mode PD120 will be used instead of PD180 which was used during previous SSTV events this year. With PD180 it takes about 3 minutes to send an image. With PD120 it takes about 2 minutes to send an image. Since images transmitted with PD120 take less time to send than with PD180, more images can be received during a single ISS pass. An ISS pass that goes right overhead (90 degrees elevation), lasts about 10 minutes. ISS SSTV transmit time and off time are usually setup to provide the radio with a 50% duty cycle (only transmit half the time so the radio doesn’t overheat). With image transmission taking two minutes, off time will probably be two minutes as well. Compared to previous SSTV events using PD180, this means it should be relatively easy to receive at least two complete images in one pass, with the possibility to receive up to three images if timing, conditions, and setup are ideal. When the ISS comes into view/has line of sight with you, this is known as Acquisition of Signal, or AOS. The ideal situation for a high elevation 10 minute pass would be if the first image started transmitting exactly at your AOS, and you had a directional antenna so you could receive the signal even while the ISS was very low in the beginning and end of the pass. In this case you would be able to receive three images like this: minute, image TX/off 0-2, complete image 1 2-4, off 4-6, complete image 2 6-8, off 8-9, complete image 3 The more common situation will be that the first image transmission will start either before or after AOS. In this case you will only have the opportunity to receive two complete images, but this is still twice the amount of images that were possible with PD180. The downside is the image quality is not as high as with PD180. Even though you’ll have the opportunity to receive two complete images, don’t expect to. It may take practice and it will certainly take the right setup and conditions, to get just one complete image. With that said, here are some tips that may help you get more images and/or better images. = Hints = == Check Twitter for #ISS #SSTV status and images == For several hours after the April and July 2015 SSTV events were scheduled to start, only a “blank signal” was transmitted. There was no audio so no images could be decoded. During these events Twitter users all over the world posted what they heard using hashtags #ISS #SSTV. As soon as people started hearing the SSTV audio, they reported it on Twitter. By searching for these hashtags you can stay up to date on the current status of the transmissions, which sometimes go longer than scheduled. Maybe more importantly, you can also see all the images people are getting! https://twitter.com/search?q=%23ISS%20%23SSTV More hints at https://spacecomms.wordpress.com/iss-sstv-reception-hints/

How to Install HDMI over CAT5e / CAT6 Ethernet Cables
Hi, this video shows you how to use the HDMI over Ethernet Cable adaptors to extend a HDMI signal using CAT6 cables. In the video I refer to 'HDMI over Ethernet' as most people call these cheap adapters that BUT really 'HDMI over Ethernet' would mean 'HDMI over IP' which is a different and more expensive product and these cheap adapters would be better called HDMI over twisted pair adapters or HDMI over CAT5E/6 adapters. In the video I use them to connect up to a PC to TV and also a Roku media player to TV. They are useful if you already have network cabling in place or if you don't want to drill big holes to install the thicker HDMI plugs/cables. If you get good ones then they will work over greater distances than HDMI cables but the versions in the videos are the cheapest available and unfortunately the advertised distance of 30m did not happen so I used 15m Ethernet cables instead and they work very well. They are very easy to use and just work as soon as you plug them in. No drivers or downloads are needed. Many thanks Vince

This video is for my students in media technical theory class, but I hope that others will enjoy it. Here's a fundamental explanation of how NTSC analog video works. Even in today's digital video universe, it's good to know the elements of analog video, as we're still living in an analog world, and because digital video equipment still starts off as analog.

How to use Wireless HDMI transreceivers to transmit HDMI signal upto 30 Meters wirelessly
MX has come up with a new video known as MX Wireless HDMI. The video shows how you can connect your HDMI transmitter And receiver upto 30 meters without using a long distance HDMI cable. Step 1: Connect the transmitter to the input source with a small HDMI cable. Step 2: Connect the IR Booster. Step 3: Connect the Receiver to the Output Source. Now you can get good quality Audio Video Signal upto 30 meters with using long cable. What is HDMI? HDMI (High-Definition Multimedia Interface) is the first and only industry-supported, uncompressed, all-digital audio/video interface. By delivering crystal-clear, all-digital audio and video via a single cable, HDMI dramatically simplifies cabling and helps provide consumers with the highest-quality home theater experience. HDMI provides an interface between any audio/video source, such as a set-top box, DVD player, or A/V receiver and an audio and/or video monitor, such as a digital television (DTV), over a single cable. HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable. It transmits all ATSC HDTV standards and supports 8-channel, 192kHz, uncompressed digital audio and all currently-available compressed formats (such as Dolby Digital and DTS), HDMI 1.3 adds additional support for new lossless digital audio formats Dolby® TrueHD and DTS-HD Master Audio™ with bandwidth to spare to accommodate future enhancements and requirements. HDMI is the de facto standard digital interface for HD and the consumer electronics market: More than 700 companies have become adopters, and nearly 200 million devices featuring HDMI are expected to ship in 2008, with an installed based of nearly one billion HDMI devices by 2010 (conservative estimates by In-Stat). Convergence -- HDMI is the interface for convergence of PC and consumer electronics devices: HDMI enables PCs to deliver premium media content including high definition movies and multi-channel audio formats. HDMI is the only interface enabling connections to both HDTVs and digital PC monitors implementing the DVI and HDMI standards.

How Do Satellites Work
http://alternatesatellitetv.blogspot.com/ A Few Words On How Does Satellite TVWork There are times when you wonder about things that you take for granted around you. For example, do you know how Satellite TVdoes work? Today the latest and most advanced transmission of TV signals are via satellite. This is a well known fact; however, few would be able to say how this is done. How Does Satellite TVWork -- The Answer Made Simple Once upon a time Satellite TVmeant a lot of expenses, a huge reception antenna plus a huge effort and cost in maintenance. Today, these same antennas have become compact and highly efficient for which they are available in almost every home. This is great for those who stay out of the coverage of terrestrial antenna or cable services because Satellite TVcan capture TV signals anywhere on earth. Regular TVs antenna uses radio waves which travel in straight line to transmit the signals. In order to receive these signals, you would need to have your own TV antenna in direct line with the main TV station terrestrial antenna. Hence, the coverage area through this process is definitely limited. Coming back to the question on how does Satellite TVwork, you will learn that the signals in this case are sent from the main TV antenna to the satellite, which acts as both a receiver and transmitter. The signals from the TV station are sent up to the satellite. The satellite orbits the earth once exactly every 24 hours making it stationary according to the movement of the earth whose rotation around its axis also takes 24 hours. This makes it possible for the satellite to distribute the signals to an immensely large area by its mere positioning. Millions of dish antennas are positioned in straight line with the satellite making it possible for you to view your favorite program on your TV. It Is Simple Once You Know How Does Satellite TVWork In other words, the Satellite TVworks the same way as the regular TV works -- the only difference being that its signals are bounced off a satellite instead of being transmitted in straight line over the surface as the case with the terrestrial antenna. In this way the signals can be dispersed over a very large area making it possible for people who live in rural or inaccessible areas to get crystal clear TV broadcast via the satellite. A small clarification about the question on how does the satellite work -- the Satellite TVdoes not have any program of its own; it rather functions as a reflector for the regular TV signals. Those who get the signals with the help of the satellite dish (as they are popularly known) antennas decode the signals with a special key which is also used to determines the cost of the service.

Digital Television
Digital TelevisionDigital TV is a system of transmission of video and audio signals from a broadcaster to a TV set, that uses digital modulation and compression to transmit data. The basis of the modern digital television is the MPEG compression standard. The current trend in broadcasting is to transmit and receive the information digitally. Even now many companies in our country offer to their subscribers TV programs in digital format, but their services are not available to all users yet. It is expected that by 2015 all citizens of Russia will be provided with digital TV based on our country's program of development of the DVB European digital television system, one of the European standards for digital television.Subjective perception of digital TV and analog TV nowadays is almost equal in the eyes of a viewer. The gain is that the quality of digital TV reception in any environment remains high, both for stationary TVs and portable ones, even in a moving vehicle.The main features that distinguish the European system of digital television from the others, are the following: more efficient use of television transmitter power, high noise immunity, adjustable speed of digital TV signal transmitter (from 5 to 32 Mbps), ability to receive digital television signals even in moving objects. One of the main characteristics is the DVB system frequency band. Is should meet the frequency band of the analog television channels, that is 8 MHz. Moreover, the medium for transmission of digital television signal remains the same: cable (cable TV) or broadcasting. In broadcasting the signal can be transmitted either by means of a satellite or by a rebroadcasting transmitter. The advantages of digital broadcasting are mostly the best viewing quality of a signal and higher bandwidth of broadcasting network.TV sets, which we have been using to this day, can't receive a digital signal. But this does not mean that you should get rid of your TV set until 2015.Any TV set, which has an antenna input, even the good old "Temp", will do. An "intermediary" between the TV set and the medium of transmission is the decoder, or the so-called set-top-box, i.e., the device that we will place at the top or near the TV. The device accepts a digital signal, converts it into the analog format and feeds it to the input of TV receiver: viewers just need to select a desired channel and watch their own, beloved and still flawless and faultless TV set. Well, and maybe by that time we will save some money to buy a new one, and we will enjoy the new product of some eastern manufacturer, even if we still doubt their guaranteed quality somewhere deep down!

Disturbing CCTV Footages With Creepy Backstories
CCTV cameras are used to surveil locations with a need for improved security and the footage is usually not published. But sometimes those cameras capture some disturbing incidences and shocking scenes; and sometimes that recordings are leaked to the public. In this video, you'll find some of the most disturbing, creepy, scary, and horrifying footages and their dark backstories. *********************************************************************** Closed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point, point to multipoint, or mesh wired or wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring such as bars, banks, casinos, schools, hotels, airports, hospitals, restaurants, military installations, convenience stores and other areas where security is needed. Video telephony is seldom called "CCTV" but the use of video in distance education, where it is an important tool, is often so called.

How to Get Better TV Reception
Watch more Tech Quick Tips videos: http://www.howcast.com/videos/403932-How-to-Get-Better-TV-Reception Fiddling around with rabbit ears can be frustrating. Use your antenna the right way to get a better signal. Step 1: Choose an antenna Choose a combined VHF/UHF antenna. As of 2009, TV signals are all digital, so antenna users need to use both signals. Step 2: Elevate the antenna Elevate the antenna as much as possible, near a window, and away from electronic equipment to get the best reception. Step 3: Adjust the antenna Adjust the antenna when you are having trouble with the signal. Moving it a few inches can drastically change the reception. Step 4: Aim towards the signal Aim the antenna towards the signal using the signal strength meter. The signal strength meter can be found on your converter box or digital television set. Tip Check the user's menu to find the signal strength meter. Step 5: Go bigger Get a larger antenna to increase your reception. Step 6: Upgrade to an outdoor antenna Upgrade to an outdoor antenna. Outdoor antennas get a clearer signal than indoor antennas. Step 7: Log on Visit a website that helps you find the best antenna for your specific location, such as AntennaWeb. Now watch TV with the clearest possible picture. Did You Know? The first wireless television remote was invented in 1955 by Robert Adler.

Cable Television
Cable TelevisionCable television is a system of television broadcasting, where the television signal is distributed with the help of high-frequency signals transmitted through cables. Cable television is totally different from ground-based or satellite broadcasting. The success in developing optical data transmission resulted in implementation of optical fiber in the cable television network. Cable television has set its ground of progressing development in Russia and in the far abroad. The processes of inventing new, and developing and expanding the old cable television networks tend to grow faster and faster year by year. It looks like after a swing towards mass liking for satellite television, high-definition television, internet broadcasting in all the different forms and moving reception television, the technical progress of the electronic mass media industry is again at the point of virtual space, when broadcasting gives way to a physical carrier.The equipment used in cable television helps to develop cable television networks of any scale providing the subscribers with all the possible services, like satellite dishes, antennas, digital receivers, head-end stations, metering equipment, optical transmitters, receivers, amplifiers, fiber optic cables, optical instruments, coaxial cables, equipment for coaxial main and subscriber networks, splitters, slots, adapters, digital equipment for head-end stations, telemetric equipment.Connecting cable TV... Instead of a gap filler, there is a fully equipped cable TV studio receiving signals of various television companies from different satellites. The signal in this studio is converted to the analogue signal, but rather than being broadcasted it is distributed through the cables to different subscribers. Each subscriber has such cable in his/her apartment, and there is absolutely no need to use an antenna. One just needs to plug in the cable into the television.So it is all very simple! Just pay the subscription fee to the operator in your district and you can enjoy broadcasted and satellite television as much as you want - 24/7. The available channels are full of entertainment programs and information with all of its myths and realities. However, you could also stick to the good old way of a regular antenna and watch the news that remain unchanged and something else useful and informational! After all, we are not yet forced to switch to digital television.

Fractal TV Antenna VS The Ultimate TV Antenna
This video is where i am comparing 2 tv antennas in identical conditions from 60 miles away from the broadcast stations.Fractal TV Antenna VS The Ultimate TV Antenna here the power pack link https://youtu.be/t0WoKdMiXfo.How to make a tv antenna.how to make a fractal tv antenna. Then a fractal antenna may be your answer. And you can make one yourself, right at home! Fractal antennas uses a fractal design to maximize the perimeter of the material that can receive and transmit electromagnetic radiation within a given total surface area or volume. Sounds complicated, right.This antenna design grew out of my attempts to build an indoor HDTV antenna using fractal patterns after I had watched a TV show and had read a magazine article on the use of fractal patterns in cell phone antennas, My goal was to design an antenna that not only worked well, but one that was easy to build and could be built from easiliy obtainable materials. The result is an antenna that is somewhat omnidirectional, and performs well receiving digital TV signals at my home from the low end of the VHF high-band (i.e Channel 7 at 174 MHZ) to the high end of the 600 MHz UHF band. (There are no channels in the 700 MHz band in my area, but Channel 51 at 692 MHz is one of the strongest signals here. diy fractal tv antenna for hd digital tv. The first thing I would like to discuss is a little history, theory, and uses for fractal antennas. Fractal antennas are a recent discovery. First discovered back in 1988 by Nathan Cohen and later published and patented in 1995. A fractal antenna has a few unique attributes as seen in this definition from Wikipedia: "A fractal antenna is an antenna that uses a fractal, self-similar design to maximize the length, or increase the perimeter (on inside sections or the outer structure), of material that can receive or transmit electromagnetic signals within a given total surface area or volume." What exactly does that mean? Well, you need to know what a fractal is. Also from Wikipedia: "A fractal is generally a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole,a property called self-similarity." So basically, a fractal is a geometric shape that repeats and appears over and over no matter how far out or how far in you zoom magnificatio Fractal antennas have been found to be approximately 20% more efficient than normal antennas. Which could be useful. Especially if you want to make your own TV antenna to pick up over the air digital or high definition video, increase your cellular range, wifi range, FM or AM radio reception, and so on. Most cell phones already have built in fractal antennas. If you noticed in the past few years that cell phones no longer have antennas on the outside. That is because they have a internal fractal antenna etched on a circuit board which allows them to get better reception and pick up more frequencies such as bluetooth, cellular, and WIFI all from one antenna at the same time "A fractal antenna's response differs markedly from traditional antenna designs, in that it is capable of operating with good-to-excellent performance at many different frequencies simultaneously. Normally standard antennas have to be "cut" for the frequency for which they are to be usedand thus the standard antennas only work well at that frequency. This makes the fractal antenna an excellent design for wideband and multiband applications." The trick is to design your fractal antenna to resonate at what ever center frequency you wish to receive. Which means it will look different and be sized different depending on what you want to receive. A little math can be used to figure this out. (Or a online calculator) In my example, I am going to make a simple one but you may want to make a more elaborate one. The more elaborate the better. I will use a spool of 18 Gauge solid core wire to make a antenna as an example but you could go as far as to etch your own circuit boards for aesthetic reasons, to make it smaller, or more elaborate with more resolution and resonance. I am going to use the example of making a TV antenna for digital or high definition reception for over the air broadcasts. It is easier to work with these frequencies and they fall around half a foot to a few feet in length for half wavelengths of the signal. I am also going to base it off a common dipole antenna for simplicity and cheapness of parts for VHF. For UHF you may want to add a director or reflector which will also make it more direction dependent. VHF is direction dependent as well but instead of pointing directly at the TV station like UHF you want VHF rabbit ears (dipole antenna) to be perpendicular to the TV station. But there is a little more design to that. I want to keep this as simple as possible as it is already a very complex subject.

Broadcast Video Wireless - How to Choose the Right Technology - Part #2
Broadcast Video Wireless - How to Choose the Right Technology http://vidovation.com/wireless-video-users-guide The Wireless Video Transmission Broadcast Guide covers: Selection Criteria Supported Bit Rates Link Distance Video Interfaces Video Formats and Compression Initial and Recurring Costs License vs. Unlicensed Spectrum Portability Antenna Types Wireless Applications Sports News Gathering Grab-and-Go Anywhere Camera's Television and Film Production Confidence Monitoring Video Assist and On-set Monitoring Wireless Technologies Traditional Private Microwave Unlicensed Wi-Fi 4G LTE/Bonded Cellular 60 GHz Uncompressed HDMI & HD SDI Summary: New technologies have greatly expanded the number of choices available to broadcasters for transporting live video from venues to studios. For example, cell-phone circuit bonding has now made it possible to transmit live video from anywhere that has good cellular coverage. Recent advances in Wi-Fi standards have increased the bitrates available for transporting video in local areas. Today, even uncompressed HD video can now be transported wirelessly using 1.5 Gigabit radio links operating at 60 GHz. Each technology has benets and drawbacks, relative to specic applications and user environments. Wireless video transport has been a key part of television broadcasting since the rst over-the-air transmission tests were performed almost a century ago. The methods used to transport video signals from one location to another have continued to push the limits of each new technology that has come along, including coaxial cable, microwave, satellite, ber optics and cellular radios. With high bandwidth signals, demanding QoS (Quality of Service) requirements and sensitivity to excessive delay, video has often been at the leading (or bleeding) edge of the capabilities of many technologies. Building on these past successes, television broadcasters today have an enormous range of wireless video transport options. These range from dedicated links that support 1.5 Gbps uncompressed HD video to highly compressed video streams that run over Wi-Fi infrastructure. In between are devices and systems to t virtually every application. With so many choices, it can be dicult to select a suitable product that oers the best combination of performance and reliability at a price point that makes sense for each project. Modern modulation technologies can pack more bits into a given amount of channel bandwidth. Changing from a modulation technique that uses two bits per symbol (such as QPSK) to one that uses four bits per symbol (such as 16QAM) will double the bit rate on a wireless link without changing the channel bandwidth. There is, of course, a cost in doing this, with more processing power needed on both ends of the connection to generate and detect these more complex signals. Plus, there is another penalty associated with the more complex modulation schemes: they are more sensitive to noise and interference. This is why Wi-Fi signals, among others, will automatically adjust their modulation (and consequently bit rate) between more simple and more complex schemes to adapt to changing RF channel conditions. Exerpt from 60GHz Section: New high-speed semiconductor technology has enabled the development of aordable, compact wireless systems that can operate in the unlicensed 60 GHz frequency range. 60 GHz systems on the market today oer completely uncompressed HD-SDI operation at 1.5 Gbps, including any embedded audio channels, metadata, SMPTE time code, etc. Because the signals are uncompressed, no encoding/decoding delay is present in the system, making it ideal for sports, live interviews and other time-sensitive applications. Solutions are also available in the 70/80 GHz and the 90 GHz frequency bands, including high speed Ethernet links that can support bi-direction GigE speeds, which is great for high performance IP video and audio networking.

Fortnite on a 1984 Panasonic Boombox
Hi, this video shows you Fortnite being played on a 34 year old Panasonic Boombox. The TV is a black & white CRT (Cathode Ray Tube) and Fortnite is being played from the Xbox One X which is then transmitting the picture and audio over the air as a RF signal. The Boombox is picking it up as an analogue signal via the antenna. The picture is far better than I thought it would be. Many thanks Vince.

Closed-circuit television
Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint, or mesh wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring such as banks, casinos, airports, military installations, and convenience stores. Videotelephony is seldom called "CCTV" but the use of video in distance education, where it is an important tool, is often so called. In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, for example when the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing digital video recorders (DVRs), provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion detection and email alerts). More recently, decentralized IP cameras, some equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation. Surveillance of the public using CCTV is particularly common in many areas around the world. In recent years, the use of body worn video cameras has been introduced as a new form of surveillance.

How To Mirror Phone To TV (No Wifi, Cable or Chrome Cast Needed)
Learn how you Mirror your Phone to TV for free. Doesn't matter what Android Phone are you using as long as it supports wifi. Well, when it comes to wifi almost any android phone does support wifi hell even the cheapest android phone has wifi these days. After doing some heavy research I even used phones from brands like Sony, Samsung, apple and LG on a Sony Bravia TV. It's not a Smart TV as many people call it "Android" in other words. It's a simple yet 4K and 3D tv. It really doesn't matter if yours is 4k or not since it's just a feature. After getting lots of questions about "No wifi" I had to make another video showing that it's not necessary to have a internet connection. Al though it'd be good to have a hot-spot running in a background and make sure the TV is connected to it. It doesn't need to be connected to internet.

How is digital TV different from analog?
This clip makes two points. First, analog's signal is different than digital's because it talks to the tuner in a different way. Second, the only thing that's changing in your television is that it needs a new tuner to understand the digital signal. Bill Hayes and Gary Sgrignoli explain.

DirecTV | Television Commercial | 2008
DirecTV | Television Commercial | 2008 DirecTV (stylized as DIRECTV or simply DTV) is an American direct broadcast satellite service provider based in El Segundo, California and is a subsidiary of AT&T. Its satellite service, launched on June 17, 1994, transmits digital satellite television and audio to households in the United States, Latin America and the Caribbean.[3][4] Its primary competitors are Dish Network and cable television providers. On July 24, 2015, after receiving approval from the United States Federal Communications Commission and United States Department of Justice, AT&T acquired DirecTV in a transaction valued at $48.5 billion.[5][6] DirecTV provides television and audio services to subscribers through satellite transmissions. Services include the equivalent of many local television stations, broadcast television networks, subscription television services, satellite radio services, and private video services. Subscribers have access to hundreds of channels, so its competitors are cable television service and other satellite-based services.[7][6] Most subscribers use reception antennas which are much smaller than the first generation antennas, which were typically a few yards (meters) across. Advances in antenna technology, including fractal antennas, have allowed a general reduction in antenna size across all industries and applications. Receiving equipment includes a satellite dish, an integrated receiver/decoder and a DirecTV access card, which is necessary to operate the receiver/decoder.[8] Consumers who purchase DirecTV subscribe to various packages of DirecTV programming for which the subscriber pays a monthly fee. Additional monthly fees may include a protection plan (which provides for repair or replacement of consumer-leased equipment from damages caused by lightning, power surges, floods, etc.), DVR, additional receivers, HD channels, and other premium channel packages. A subscriber also can order pay-per-view and video on demand events and movies. DirecTV contracts with and pays program providers such as cable networks, motion picture distributors, sports leagues, event promoters, and other programming rights holders, for the right to distribute their programming to its subscribers. All programming distributed by DirecTV is delivered to its broadcast centers in Castle Rock, Colorado, and Los Angeles, where it is then digitized and compressed. The resulting signal is encrypted by DirecTV to prevent its unauthorized reception. DirecTV then transmits these signals to several satellites located in geostationary orbit.[8] As of Q1 2017, DirecTV U.S. had 21 million subscribers (26 million if combined with U-verse) and revenues of $12 billion. In addition to serving residences, DirecTV offers service to bars, restaurants, hotels, dorms, and hospitals through their DirecTV for business service. The company also offered mobile service for cars, boats, and RVs (DirecTV Mobile) as well as aircraft (DirecTV Airborne) in cooperation with Connexion by Boeing. On November 30, 2016, DirecTV Now, an internet streaming TV service was launched.

Ability to do multiple repeaters application up to 5 pieces with distance 1KM (Max.) Ability to send power to next repeater unit over coax cable from the remote repeater (nearest the DVR) when using 2 piece or more than 2 pieces Long range installation new network architectures to take advantage of the fiber's strengths. What is SDI? Serial digital interface [SDI] standard is based on a 270 Mbps transfer rate, over a single 75 ohm coaxial cable [BNC connector], up to 600 feet. Serial Digital Interface is a [standard definition] digital broadcast television standard providing a lossless digital encoding of standard NTSC and PAL formats [with embedded audio]. SDI is used in Television stations, cable channels, and professional production Equipment. SDI provides a method for transmitting uncompressed digital video, audio and other data between video devices. SDI is described in ITU R BT 601 standard for interface of component digital video. SDI is defined in SMPTE259M and ITU-R BT.656 standards. SMPTE259M defines four standard bit rates from 143Mbps to 360Mbps [ 270Mps is common]. SMPTE 344M adds a 540Mbps bit rate. One component of luminance (with 720 samples per line), and two of color (each with 360 samples per line). There are either 10 or 8 bits per sample [scrambled, polarity independent interface, with common scrambling for both component ITU-R 601 and composite digital video and four channels of (embedded) digital audio]. The SDI bit stream is encoded using a pseudo-random scramble followed by a NRZ-to NRZI conversion. The scramble code is x9+ x4+1. What is HD-SDI? HD-SDI stands for High-Definition Serial Digital Interface. It is the common term for a high-definition digital video transmission standard known as SMPTE 292M. The SMPTE 292M standard is part of a family of Serial Digital Interface standards that use a coaxial cable to transport uncompressed digital video -- currently still predominantly used in professional TV studios. In short, HD-SDI is a standard for transmitting uncompressed broadcast-grade HD video signals over short distances (although longer distances are possible with fibre optic cables). More than 400 interface standards are published by the Society of Motion Picture and Television Engineers (SMPTE), an internationally recognised industry organisation that develops common standards, practices and guidelines mostly for television and cinema. HD-SDI Bit Rates The 292M interface of the HD-SDI standard has a nominal data rate of 1.5 Gbps. To be precise, the standard specifies two exact bit rates: a) 1.485 GbpsSupports 60 Hz, 50 Hz, 30 Hz, 25 Hz, 24 Hz and other commonly used frame rates. b) 1/485/1.001 GbpsAllows the standard to support video formats with frame rates of 59.94 Hz, 29.97 Hz and 23.98 Hz, making it upwards compatible with existing NTSC (analogue video) systems.

Surveillance of the public using CCTV is particularly common in many areas around the world. In recent years, the use of body worn video cameras has been introduced as a new form of surveillance. Use in schools In the United States and other places, CCTV may be installed in school to monitor visitors, track unacceptable student behavior and maintain a record of evidence in the event of a crime. There are some restrictions on installation, with cameras not being installed in an area where there is a reasonable expectation of privacy , such as bathrooms, gym locker areas and private offices (unless consent by the office occupant is given). Сameras are generally acceptable in hallways, parking lots, front offices where students, employees, and parents come and go, gymnasiums, cafeterias, supply rooms and classrooms. The installation of cameras in classrooms may be objected to by some teachers. Criminal use Criminals may use surveillance cameras to monitor the public. For example, a hidden camera at an ATM can capture peoples PINs as they are entered, without their knowledge. The devices are small enough not to be noticed, and are placed where they can monitor the keypad of the machine as people enter their PINs. Images may be transmitted wirelessly to the criminal. Home Security In the early to mid 2000s, companies including ADT, LiveWatch, and SimpliSafe started offering CCTVs to the consumer market for home safety and security. Cameras typically come as part of alarm monitoring packages that may also include fire and flood detection. cctv camera strange caught on camera

Broadcast Television on Your Phone? | ABC v. Aereo
Want a specific SCOTUS case covered? Your idea gets picked when you donate on Patreon: https://www.patreon.com/iammrbeat Mr. Beat's band: http://electricneedleroom.net/ Mr. Beat on Twitter: https://twitter.com/beatmastermatt In episode 14 of Supreme Court Briefs, a company trying to show broadcast television on phones and tablets gets sued by, you guessed it, broadcast companies. Check out cool primary sources here: https://www.oyez.org/cases/2013/13-461 Additional sources used: https://www.nytimes.com/2014/06/26/business/media/supreme-court-rules-against-aereo-in-broadcasters-challenge.html?_r=0 http://www.scotusblog.com/case-files/cases/american-broadcasting-companies-inc-v-aereo-inc/ https://www.supremecourt.gov/opinions/13pdf/13-461_l537.pdf http://www.slate.com/articles/technology/future_tense/2014/06/abc_v_aereo_ruling_the_supreme_court_s_terrible_technological_analogies.html New York City March 14, 2012 A company called Oreo launches. Uh yeah, they provide the best cookies around, and...hold up...wait a minute...my mistake, I’m sorry. A company called Aereo (air-e-o) launches, allowing people to view live broadcast television on Internet-connected devices. For $8 to $12 a month, viewers could access the airwaves on their phone or tablet no matter where they were. Well a bunch of broadcasting companies didn’t like that so much. Two weeks before the launch, ABC, CBS, NBC, and FOX had all sued Aereo, arguing that the company threatened their copyrighted material because the streaming of live broadcast television in this way counted as a “public performance,” which means they needed to get a special license. The four broadcasting companies argued that Aereo broke part of the interestingly named Cable Television Consumer Protection and Competition Act, which said you have to negotiate with broadcasters before you carry their signals. ABC, CBS, NBC, and FOX all basically said Aereo was stealing both their programming and customers. After the broadcasting companies failed to stop the launch of Aereo in federal court, they appealed to the U.S. Court of Appeals for the Second Circuit. This court agreed with the lower court, saying Aereo had the right to do this as their streams to subscribers were not “public performances,” so there wasn’t copyright infringement. This happened on April 1, 2013. By this time, Aereo was quickly growing and expanding across the country, getting awesome reviews from both the media and customers. But the broadcasting companies weren’t done yet...obviously. I’ve found corporations tend to have a lot of money to take others to court, for some strange reason. Anyway, the broadcasters appealed to the Supreme Court, and on January 10, 2014, the Court agreed to hear the case. This time around, the broadcasters had lots of allies, including the NFL, Major League Baseball, the Department of Justice, the United States Copyright Office, and some judge in the 10th Circuit Court of Appeals, who blocked Aereo in his district. Probably due to those allies, it was not looking good for Aereo. On June 25, 2014, the Court ruled in favor of the broadcasters, 6-3, and against Aereo. The Court explained Aereo was definitely breaking copyright law as it acted like a cable company that rebroadcasted copyrighted content. Justice Antonin Scalia wrote for the dissenting minority, saying the Court should not be making judgements on new technologies- it was the job of Congress. Before the Supreme Court decision, Aereo had about 80,000 subscribers. Well, three days after the decision, they all lost the service. Aereo filed for bankruptcy on November 21, 2014, and was later bought by TiVo for $1 million. American Broadcasting Companies, Inc. v. Aereo, Inc. kept the status quo in broadcasting. Many argue it limited innovation. Critics say it’s likely the consumers who got screwed over the most in this one. #supremecourt #scotus #apgov

Closed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint (P2MP), or mesh wired or wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring such as banks, stores, and other areas where security is needed. Though Videotelephony is seldom called 'CCTV' one exception is the use of video in distance education, where it is an important tool. Surveillance of the public using CCTV is common in many areas around the world. In recent years, the use of body-worn video cameras has been introduced as a new form of surveillance, often used in law enforcement, with cameras located on a police officer's chest or head. Video surveillance has generated significant debate about balancing its use with individuals' right to privacy even when in public.
