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

Satellite Communication - Defintion, Principle, Polar Circular orbit
Satellite Communication Satellite communication is the branch of telecommunication which establishes and communication using satellites across the globe.We can divide the whole satellite communication into two parts namely space segments and earth segments.Satellite communication uses highly sophisticated and secured communication methods and algorithms.In satellite communication we use microwave frequencies ranging from 1GHz to 40 GHz which is further divided into various bands.In satellite communication we use multiplexing techniques such as FDMA,TDMA,CDMA etc which enables the bandwidth utilization.In the process of design we have to consider many parameters such as path loss,propagation loss,noise factors,atmospheric loss etc. Checkout for more information: https://www.tutorvista.com/content/physics/physics-ii/space-exploration/communication-satellites.php Follow us at: https://www.facebook.com/tutorvista https://twitter.com/TutorVista

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 .

How To Make DTV Antenna (My Way) (ISDB-T Philippines)
When I bought a ABS-CBN TVplus box it includes a vertical standing antenna with a magnet at the bottom so you can stick it to a metal surface so I decided to make an experiment by comparing the antenna polarization and discovered that the signal is stronger in vertical than horizontal (unlike analog which is the opposite). No idea if you get the same result as I did but here's my result: ABS-CBN TVplus own vertical standing antenna which I placed on top of cabinet inside the house = 44% Outdoor antenna horizontally polarized = 56% Outdoor antenna vertically polarized = 67% The picture quality is exactly the same because in digital if the signal is above the threshold you got a perfect picture but below the threshold no picture at all so the picture quality of 30% is identical to 100% (see cliff effect https://en.wikipedia.org/wiki/Cliff_effect). I made this video just in case if you are in area which signal is difficult to receive this video might help you. However if you can receive a stable signal using the ABS-CBN TVplus own indoor antenna then there's no benefit in making outdoor antenna because in digital once you see the picture it's perfect. Vertical antenna should not be use in analog because they are transmitted horizontally. UPDATE: Vertical antenna is not ideal in North America because most DTV over there are transmitted horizontally. They also continued using the VHF band on DTV along with UHF but VHF requires larger antenna than UHF and the length of antenna I showed in this video is for UHF only. VHF had been abandoned in most countries for DTV.

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

COMMUNICATION SYSTEMS: BANDWIDTH OF SIGNAL: In a communication system, the message signal can be voice, music, picture or computer data. Each of these signals has different ranges of frequencies. The type of communication system needed for a given signal depends on the band of frequencies which is considered essential for the communication process. For speech signals, frequency range 300 Hz to 3100 Hz is considered adequate. Therefore speech signal requires a bandwidth of 2800 Hz 3100 hertz – 300 hertz for commercial telephonic communication. To transmit music, an approximate bandwidth of 20 kHz is required because of the high frequencies produced by the musical instruments. The audible range of frequencies extends from 20 Hz to 20 kHz. Video signals for transmission of pictures require about 4.2 MHz of bandwidth. A TV signal contains both voice and picture and is usually allocated 6 MHz of bandwidth for transmission.In the preceeding paragraph, we have considered only analog signals. Digital signals are in the form of rectangular waves as shown in Figure. However, for practical purposes, the contribution from higher harmonics can be neglected, thus limiting the bandwidth. As a result, received waves are a distorted version of the transmitted one. If the bandwidth is large enough to accommodate a few harmonics, the information is not lost and the rectangular signal is more or less recovered. This is so because the higher the harmonic, less is its contribution to the wave form.

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.

Diginets - Digital subchannel - Over the air FREE TV
THE HAPPY SATELLITE NERD EPISODE 77 In broadcasting, digital subchannels are a method of transmitting more than one independent program stream simultaneously from the same digital radio or television station on the same radio frequency channel. This is done by using data compression techniques to reduce the size of each individual program stream, and multiplexing to combine them into a single signal. The practice is sometimes called "multicasting". #FTA #FreeToAir #SatelliteTV #FreeTV #TVRO #AntennaTV #Streaming #TV #cordcutting #OTT These channels can work with orby tv The ATSC digital television standard used in the United States supports multiple program streams over-the-air, allowing television stations to transmit one or more subchannels over a single digital signal. A virtual channel numbering scheme distinguishes broadcast subchannels by appending the television channel number with a period digit (".xx"). Simultaneously, the suffix indicates that a television station offers additional programming streams. By convention, the suffix position ".1" is normally used to refer to the station's main digital channel and the ".0" position is reserved for analog channels. For example, most of the owned-and-operated stations/affiliates of Ion Television transmit six streams in the following format: Canada Although digital television services in Canada use the same ATSC technology as the United States, none of the stations currently broadcasting a digital signal transmit any subchannel other than a possible HD service or a standard definition simulcast of the main channel. Unlike the FCC in the United States, the body that governs Canadian broadcasting licenses, the Canadian Radio-television and Telecommunications Commission (CRTC), requires stations to file license amendments in order to be considered for permission to carry digital subchannels (this differs from the Commission's rules for premium cable television services, which allow the addition of multiplex channels consistent with the service's license requirements without the need to amend the license). On August 17, 2012, the CRTC gave approval to Leamington, Ontario community station CFTV-TV to broadcast four local subchannels on its digital signal, making it the first station in Canada to launch original content on its multiplex channels.

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 Analog Video Works
There are a lot of short videos on analog video, but you'd have to watch a lot of them to get the full picture, and there's a fair bit of misinformation out there. 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.

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.

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.

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.

In radio and electronics, an antenna (plural antennae or antennas), or aerial, is an electrical device which converts electric power into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter supplies an electric current oscillating at radio frequency (i.e. a high frequency alternating current (AC)) to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage at its terminals, that is applied to a receiver to be amplified. Antennas are essential components of all equipment that uses radio. They are used in systems such as radio broadcasting, broadcast television, two-way radio, communications receivers, radar, cell phones, and satellite communications, as well as other devices such as garage door openers, wireless microphones, Bluetooth-enabled devices, wireless computer networks, baby monitors, and RFID tags on merchandise. Typically an antenna consists of an arrangement of metallic conductors (elements), electrically connected (often through a transmission line) to the receiver or transmitter. An oscillating current of electrons forced through the antenna by a transmitter will create an oscillating magnetic field around the antenna elements, while the charge of the electrons also creates an oscillating electric field along the elements. These time-varying fields radiate away from the antenna into space as a moving transverse electromagnetic field wave. Conversely, during reception, the oscillating electric and magnetic fields of an incoming radio wave exert force on the electrons in the antenna elements, causing them to move back and forth, creating oscillating currents in the antenna. Antennas can be designed to transmit and receive radio waves in all horizontal directions equally (omnidirectional antennas), or preferentially in a particular direction (directional or high gain antennas). In the latter case, an antenna may also include additional elements or surfaces with no electrical connection to the transmitter or receiver, such as parasitic elements, parabolic reflectors or horns, which serve to direct the radio waves into a beam or other desired radiation pattern. The first antennas were built in 1888 by German physicist Heinrich Hertz in his pioneering experiments to prove the existence of electromagnetic waves predicted by the theory of James Clerk Maxwell. Hertz placed dipole antennas at the focal point of parabolic reflectors for both transmitting and receiving. He published his work in Annalen der Physik und Chemie (vol. 36, 1889). Yagi antenna A commonly used directional antenna is the Yagi-Uda Array, usually just called a Yagi. It was invented by Shintaro Uda and his colleague, Hidetsugu Yagi, in 1926. A Yagi antenna uses several elements to form a directional array. A single driven element, typically a dipole, propagates RF energy; elements placed immediately in front of and behind the driven element re-radiate RF energy in phase and out of phase, enhancing and retarding the signal, respectively. The elements are called parasitic elements; the element behind the driven element is called the reflector, while the elements in front of the driven element are called directors. Yagi antennas have beamwidths in the range of 30 to 80 degrees and can provide well in excess of 10 dBi passive gain.

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 (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. For more information visit our website-: https://www.ajath.com

UHF & VHF Signal in Brazil
Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 MHz and 3 GHz, also known as the decimetre band as the wavelengths range from one meter to one decimeter. Radio waves with frequencies above the UHF band fall into the SHF (super-high frequency) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications. The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz. Two other IEEE radar bands overlap the ITU UHF band: the L band between 1 and 2 GHz and the S band between 2 and 4 GHz. Radio waves in the UHF band travel almost entirely by line-of-sight propagation (LOS) and ground reflection; there is very little reflection from the ionosphere (skywave propagation), or ground wave. They are blocked by hills and cannot travel far beyond the horizon, but can penetrate foliage and buildings for indoor reception. Since the wavelengths of UHF waves are comparable to the size of buildings, trees, vehicles and other common objects, reflection and diffraction from these objects can cause multipath propagation, especially in built-up urban areas. Atmospheric moisture reduces, or attenuates, the strength of UHF signals over long distances, and the attenuation increases with frequency. UHF TV signals are generally more degraded by moisture than lower bands, such as VHF TV signals. Occasionally when conditions are right, UHF radio waves can travel long distances by tropospheric ducting as the atmosphere warms and cools throughout the day. The length of an antenna is related to the length of the radio waves used. The UHF antenna is stubby and short; at UHF frequencies a quarter-wave monopole, the most common omnidirectional antenna is between 2.5 and 25 cm long for example. The short wavelengths make the VHF and UHF bands the first bands at which practical transmitting antennas are small enough to mount on handheld devices, thus these frequencies are used for portable wireless devices. UHF is widely used in cordless telephones, cell phones, walkie-talkies and other two-way radio systems from short range up to the visual horizon, about 40 miles (64 km). Their transmissions do not travel far, allowing frequency reuse. Public safety, business communications and personal radio services such as GMRS, PMR446, and UHF CB are often found on UHF frequencies as well as IEEE 802.11 wireless LANs ("Wi-Fi"). The widely adapted GSM and UMTS cellular networks use UHF cellular frequencies. Radio repeaters are used to retransmit UHF signals when a distance greater than the line of sight is required. Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 MHz to 300 MHz, with corresponding wavelengths of ten to one meters. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). Common uses for VHF are FM radio broadcasting, television broadcasting, two way land mobile radio systems (emergency, business, private use and military), long range data communication up to several tens of kilometres with radio modems, amateur radio, and marine communications. Air traffic control communications and air navigation systems (e.g. VOR & ILS) work at distances of 100 kilometres or more to aircraft at cruising altitude. VHF was used for analog television stations in the US, and continues to be used for digital television as well as in Europe but in the latter only Band III is used even though originally Band I was planned to be used. Some older DVB-T receivers included channels E2 to E4 but newer ones only go down to channel E5. VHF propagation characteristics are suited for short-distance terrestrial communication, with a range generally somewhat farther than line-of-sight from the transmitter (see formula below). VHF waves are restricted to the local radio horizon less than 100 miles. VHF is less affected by atmospheric noise and interference from electrical equipment than lower frequencies. While it is blocked by land features such as hills and mountains, it is less affected by buildings and can be received indoors, although multipath television reception due to reflection from buildings can be a problem in urban areas. Unlike high frequencies (HF), the ionosphere does not usually reflect VHF waves (called skywave propagation). VHF waves can be aided by tropospheric ducting.

How to extend an HDMI signal
HowToAV look at the distance limitations of HDMI signal transmission and offers a range of solutions to extend your signal. HDMI - or 'High Definition Multimedia Interface' - provides a combined HD video and audio signal for commercial and residential AV systems. HDMI cables are limted in their transmission distance, with the maximum recommended cable length being no more than 10 to 15 metres only. So there are a number of different options which will allow for a HDMI signal to be extended, including: - HDMI Equaliser - allows 2 x 15 metre HDMI cables to be connected together and recalculates the signal, allowing for a total distance of 30 metres. - HDMI Repeater, Distribution Amplifier or HDMI Splitter - Extends the HDMI signal and usually also 'duplicates' the HDMI signal for connecting to multiple output displays / TVs. - HDMI-over-Cat cable Extender Kits - feature a Transmitter and Receiver device whihch convert the HDMI siganl for transmission over standard Ethernet cable over distances of 60 - 100 metres. - HDBaseT - transmits HDMI signals simultaneously with PoE, 100BaseT and control signals over Cat5e/6/7 cable up to 100 metres Find out more about HDMI signal tranmission in the HowToAV HDMI blog here: http://www.cie-group.com/blog/3/hdmi-signal-distribution?page=1 #HowToAV Got more questions for the HowToAV team to take a look at?

CCTV Accident Caught on Tape Compilation
CCTV accident Caught on Tape Compilation CCTV or 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 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. 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
