How To connect HD Multi Room TV, 1 source to 4 TVs using HDMI Splitters / Amplifiers
 
13:32
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

How Radio Waves Are Produced
 
04:58
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
 
03:58
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
 
05:59
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.

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.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). https://en.wikipedia.org/wiki/Radio Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ Radio is the transmission of signals through free space by electromagnetic waves with frequencies significantly below visible light, in the radio frequency range, from about 3 kHz to 300 GHz. These waves are called radio waves. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space. Information, such as sound, is carried by systematically changing (modulating) some property of the radiated waves, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form... Transmitter and modulation Each system contains a transmitter. This consists of a source of electrical energy, producing alternating current of a desired frequency of oscillation. The transmitter contains a system to modulate (change) some property of the energy produced to impress a signal on it. This modulation might be as simple as turning the energy on and off, or altering more subtle properties such as amplitude, frequency, phase, or combinations of these properties. The transmitter sends the modulated electrical energy to a tuned resonant antenna; this structure converts the rapidly changing alternating current into an electromagnetic wave that can move through free space (sometimes with a particular polarization). Amplitude modulation of a carrier wave works by varying the strength of the transmitted signal in proportion to the information being sent... It was the method used for the first audio radio transmissions, and remains in use today. "AM" is often used to refer to the mediumwave broadcast band (see AM radio). Frequency modulation varies the frequency of the carrier. The instantaneous frequency of the carrier is directly proportional to the instantaneous value of the input signal... FM is commonly used at VHF radio frequencies for high-fidelity broadcasts of music and speech (see FM broadcasting). Normal (analog) TV sound is also broadcast using FM... An antenna (or aerial) is an electrical device which converts electric currents into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter applies an oscillating radio frequency electric current 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. An antenna can be used for both transmitting and receiving... Once generated, electromagnetic waves travel through space either directly, or have their path altered by reflection, refraction or diffraction. The intensity of the waves diminishes due to geometric dispersion (the inverse-square law); some energy may also be absorbed... Electrical resonance of tuned circuits in radios allow individual stations to be selected. A resonant circuit will respond strongly to a particular frequency, and much less so to differing frequencies. This allows the radio receiver to discriminate between multiple signals differing in frequency... The electromagnetic wave is intercepted by a tuned receiving antenna; this structure captures some of the energy of the wave and returns it to the form of oscillating electrical currents. At the receiver, these currents are demodulated, which is conversion to a usable signal form by a detector sub-system. The receiver is "tuned" to respond preferentially to the desired signals, and reject undesired signals. Early radio systems relied entirely on the energy collected by an antenna to produce signals for the operator...

Digital Television
 
03:56
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!

How Do Satellites Work
 
05:37
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.

02:11
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 to Install HDMI over CAT5e / CAT6 Ethernet Cables
 
11:10
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

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.

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.

Temple Theft Caught On CCTV Footage In India
 
02:20
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.[1][2] 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-based CCTV 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 including the United Kingdom, where there are reportedly more cameras per person than in any other country in the world.[3] There and elsewhere, its increasing use has triggered a debate about security versus privacy.

How Analog Video Works
 
09:24
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
 
03:31
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.
