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 .

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...

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.

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

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

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.

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/

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.

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!

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.

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

Nyrius Aries Prime Wireless HD Transmitter
I am a fan of the Nyrius Aries Prime - it allows me to wirelessly transmit an H signal from my computer, cable box, and even my iPad to my HD television. The wirelss connection allows you to eliminate and/or add new devices to your home media center. You can see in the video that I am using it with my iPad to mirror my iPad's screen on to my television. The primary purpose is to mirror your laptop's screen to your television, but you will be able to find other uses too. Notes - Comes with a HD Transmitter which is slightly larger than a standard USB flash drive. The tranmistter does require power - either through the included AC adapter or a USB-to-mini USB connector (which allows both your laptop or an external battery pack to provide power). - The HD receiver is about the size of two decks of cards and can be mounted to a wall behind your television. It does require power and comes with a second ac power adapter. - Also comes with an L-shaped HDMI connector and a HDMI cable - Supports full HD at 1080P and 3D playback - I have not noticed any type of latency - except when the unit got hot (Which was being provided by an external source) . Make sure that you do not place the Nyrius receiver on a heat source (like a cable box or anything else that gets hot). - The transmitter and receivers paired almost instantly - and I was able to go from the box to a complete set-up in 5-10 minutes. - In the video you can see how I was able to use the Aries Prime with my iPad (although it does require some additional accessories - such as a 30pin-to-HDMI connector). Final Verdict - The ability to wireless transmit and receive wirelss HD signals offers you a lot of flexibility in your home media devices. The Nyrius Aries Prime allows you to plugin a transmitter into the HDMI port of laptop and immediately begin to stream a wireless HD signal. It is easy to set-up and works very well so it is an easy recommendation. 5 Stars Please Note I received this product in exchange for an unbiased review Check out the Adventures of The Assistant and Wiggles!

AM Radio History
The technology of amplitude modulation (AM) radio transmission was developed during the two decades from 1900 to 1920. Before this, the first radios transmitted information by wireless telegraphy, in which the radio signal didn't carry audio (sound) but was switched on and off to create pulses that carried text messages in Morse code. This was used for private person-to-person traffic, similar to telegrams. The first AM radio transmission took place in 1906 from a garage in Brant Rock, Massachusetts. After six years of hard work, Reginald Fessenden, a Canadian inventor transmitted the world's first voice message by using an Alexanderson alternator and a rotary spark-gap transmitter. His message was heard by radio-equipped ships within a range of several hundred miles away from the transmission point. https://engineers-channel.blogspot.com/p/am-radio-history.html

Episode 41 - High Speed Wireless Networking on 420 MHz, from the DCC
From the DCC - David Bern W2LNX plays with some inexpensive, very low power off-the-shelf data radios that can be brought into the 420 MHz band.

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

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?
