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.

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.

An over simplified block diagram of a monochrome TV transmitter is shown in animation. The functional block diagram can be broadly divided into two sections, viz. an amplitude modulated transmitter and a frequency modulated transmitter. Former is used for video modulation, whereas latter is used for audio modulation. In Monochrome TV transmission, the synchronising and scanning circuits produce sets of pulses for providing synchronising pulses for proper functioning of the TV system. This timing unit contains number of wave generating and wave shaping circuits. The repetition rate of its various output pulse trains is controlled by a frequency stabilised master oscillator. The output signal of a camera tube corresponding to the image to be televised is amplified through a number of video amplifier stages. The image signals together with the synchronising and blanking pulses are raised to a level suitable for modulating the RF carrier wave generated in the RF channel. The allotted picture carrier frequency is generated by the crystal controlled oscillator. The continuous wave output is given large amplification before feeding to the power amplifier. In the modulator, its amplitude is made to vary in accordance with the modulating signal received from the modulating amplifier. The microphone converts the sound associated with the picture being televised into proportionate electrical signal. The audio signal from the microphone after amplification is frequency modulated, employing the assigned carrier frequency. The output of the sound FM transmitter is finally combined with the AM picture transmitter output, through a combining network and fed to a common antenna for radiation of energy in the form of electromagnetic waves.

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.

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.

Using a digital pin, shifting out a signal at 80 MHz to broadcast analog tv to an analog tv on channel 3. Whooh! Github: http://github.com/cnlohr/channel3 I was playing around with the I2S bus on the ESP8266 and found that it could output the I2S port at 80 MHz and still maintain the DMA!

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

Analog TV Transmitter. According to an article published on wikipedia, the analog TV transmission is separate in two parts. The video is transmitted using an Amplitude Modulated (AM) signal and the audio using a Frequency Modulated (FM) signal. My idea was to have two transmitters so I would be able to transmit two signals with different modulation structures. The issue was that by tuning both transmitters to a close frequency one interfered in the other, so I decided to tune the audio frequency in a higher frequency to avoid interference and used a radio to receive the audio signal. Below are the links to the schematics I have based my project on: Video transmitter based on the circuit available at: http://www.circuitdiagram.org/tv-transmitter-circuit.html Audio Transmitter based on the circuit available at: http://www.newtoncbraga.com.br/index.php/mini-projetos/174-transmissores-e-receptores/6859-transmissor-de-fm-min121

Top 10 creepy mysterious radio and television transmissions. Coded government, paranormal or alien messages. Subscribe to our channel: http://goo.gl/9CwQhg Description: When it comes to enjoying entertainment, we are comforted by the fact that there is security and consistency in various forms of broadcasting from radio to television thanks to rules and regulations. If you’re not an engineer, basically the way that these broadcasts work is that there are satellite dishes and signals that run through the sky and electrical wiring to bring you the entertainment that you so desire. Almost on a regular basis, things go smoothly. Notice how we say, “almost”? When you’re dealing with radio waves and television signals, occasionally someone else figures out how to infiltrate the system and hijack the broadcast. This is equally alarming for the both the audience and station executives, as you don’t know what will come through the speakers or the screen. There could be a gruesome message or image that will upset the public, corrupt the children, or expose confidential information. For decades, originating in the 20th century, there have been numerous interruptions in broadcasting. Usually it is pretty easy to detect the origin and the perpetrator. But when the source of the hijacking isn’t found, there is a sense of unease that leaves us to wonder when will another interruption strike again. In this video are ten strange and unexplained broadcasts that have made an impact on our modern day society and how big of a role censorship plays in modern day media. However, it is important to note that after the first world war, it came out that there was a plethora of radio stations that became known as “numbers stations”, meaning that they would broadcast weird transmissions that acted as messages for spy agencies. This means that instead of sending letters, Morse code messages, or anything that could be easily intercepted, spies and government agencies tuned into radio stations for their messages and orders. It sounds like a conspiracy theory, but things such as these actually happened during times of war. The Lincolnshire Poacher station is considered to be a numbers station, with the English folk song signaling the beginning of the broadcast, and the song closing the broadcast. UVB-76 is also considered to be a numbers stations with buzz tones changing pitch about 25 times per minute that occurs 24 hours a day, and then a Russian voice interrupting the broadcast on occasion. Sometimes, broadcast interruptions happened because of jokers and people who wanted to inflict discomfort onto the public. For example, in 1977, the Southern Television Broadcast was an incident consisting of a voice overriding the audio system and sounding like a message from outer space. Some people may have heard the broadcast and chalked it up to jokers, while others may have actually thought that the broadcast was from aliens and that the world was on the brink of an invasion. Sometimes interruptions occurred due to political and protesting reasons. For more strange and unexplained broadcasts, check out the rest of the video. Some of these broadcasts may confuse you, make you laugh, or positively terrify you.

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.

THE HAPPY SATELLITE NERD EPISODE 9 Free-to-air (FTA) are television (TV) and radio services broadcast in clear (unencrypted) form, allowing any person with the appropriate receiving equipment to receive the signal and view or listen to the content without requiring a subscription, other ongoing cost or one-off fee (e.g. Pay-per-view). In the traditional sense, this is carried on terrestrial radio signals and received with an antenna. FTA also refers to channels and broadcasters providing content for which no subscription is expected, even though they may be delivered to the viewer/listener by another carrier for which a subscription is required, e.g. cable, satellite or the Internet. These carriers may be mandated (or opt) in some geographies to deliver FTA channels even if a premium subscription is not present (providing the necessary equipment is still available), especially where FTA channels are expected to be used for emergency broadcasts, similar to the 112 emergency service provided by mobile phone operators and manufacturers. Free-to-view (FTV) is, generally, available without subscription but is digitally encoded and may be restricted geographically. Free-to-air is often used for international broadcasting, making it something of a video equivalent to shortwave radio. Most FTA retailers list free to air channel guides and content available in North America for free to air use. With a fta System you can receive several free Christian tv channels on Galaxy 19 97w The Word Network, 3ABN English, Smart LifeStyle TV, LLBN His Word, Amazing Discoveries TV, Amazing Facts TV, 3ABN Proclaim, Hope Channel Church,Hope Channel, Kingdom Life Network, Daystar TV, Angel TV America, TBN US, Hillsong Channel, Smile TV (Smile of a Child), Juce TV (jctv) GCN America Apostolic Oneness Network CTN (USA) Bible Explorations TV, The University Network (Pastor Gene Scott and Melissa scott) God's Learning Channel, Logos TV And also get Tuff TV, Jewelry TV, QVC US, Press TV The Second part of the video I show how to find channels on lyngsat https://www.lyngsat.com/Galaxy-19.html A resorce where you can find all free to air programs on satellite mentioning the tv services and radio services such as Also many Radio services such as Republic Broadcasting Network, Sonshine Radio, The Liberty Radio Network, LRN, KNLB Christian Radio, SFA, GCN, Jeff Rense radio, The Overcomer (Ralph Gordon Stair), Sputnik International, The Micro Effect, American Voice Radio Network, WRN English North America etc The cost of a basic Free to air system receiving Galaxy 19 is maybe just a little over $200 less if you have had a subscription service that you are no longer using.

Col. Donald Ware, U.S. Air Force (ret.) passes on this reminder of the time 27 years ago when the Star Visitors took over a British television program and broadcasted instead an important message for the people of Earth. [The transmission] occurred on 26 Nov 77 at 5:12 p.m. when a strange unknown voice overrode, took over, or super-modulated the TV signals from five transmitters that were monitored by the Independent Broadcasting Authority (IBA) in England. IBA did not detect the intrusion. The 5+1/2-minute message overrode a scheduled newscast read by Ivor Mills on Southern ITV, England, and was heard by listeners as far away as Andover, London, Newbury, Oxford, Reading, Southhampton, and Winchester. IBA engineers at Croydon, Surry did not hear the override, and at the main transmitter at Southhampton, Hants monitoring system, there was also no evidence of the takeover. A police spokesman told AP and UPI that the message was taken seriously: "They were frightened and generally scared." The voice spoke slowly and deliberately, with a strange inward authority, calm, serene, never scolding. It said: This is the voice of Gramaha, the Representative of the Asta (Ashtar in some texts) Galactic Command speaking to you. For many years now you have seen us as lights in the skies. We speak to you now in peace and wisdom as we have done to your brothers and sisters all over this, your planet earth. We come to warn you of the destiny of your race and your worlds so that you may communicate to your fellow beings the course you must take to avoid the disasters which threaten your worlds and the beings on our worlds around you. This is in order that you may share in the great awakening, as the planet passes into the New Age of Aquarius. The new age can be a time of great peace and evolution for your race, but only if your rulers are made aware of the evil forces that can overshadow their judgments. Be still now and listen, for your chance may not come again. For many years your scientists, governments and generals have not heeded our warnings; they have continued to experiment with the evil forces of what you call nuclear energy. Atomic bombs can destroy the earth and the beings of your sister worlds, in a moment. The wastes from atomic power systems will poison your planet for many thousands of your years to come. We, who have followed the path of evolution for far longer than you, have long since realized this -- that atomic energy is always directed against life. It has no peaceful application. Its use, and research into its use, must be ceased at once, or you all risk destruction. All weapons of evil must be removed. The time of conflict is now past and the race of which you are a part may proceed to the highest planes of evolution if you show yourselves worthy to do this. You have but a short time to learn to live together in peace and goodwill. Small groups all over the planet are learning this, and exist to pass on the light of the dawning new age to you all. You are free to accept or reject their teachings, but only those who learn to live in peace will pass to the higher realms of spiritual evolution. Hear now the voice of Gramaha, the representative of the Asta (Ashtar in some texts) Galactic Command speaking to you. Be aware also that there are many false prophets and guides operating on your world. They will suck your energy from you -- the energy you call money and will put it to evil ends giving you worthless dross in return. Your inner divine self will protect you from this. You must learn to be sensitive to the voice within, that can tell you what is truth, and what is confusion, chaos and untruth. Learn to listen to the voice of truth which is within you, and you will lead yourselves on to the path of evolution. This is our message to you our dear friends. We have watched you growing for many years as you too have watched our lights in your skies. You know that we are here, and that there are more beings on and around your earth than your scientists admit. We are deeply concerned about you and your path towards the light, and will do all we can to help you. Have no fears, seek only to know yourselves and live in harmony with the ways of your planet earth. We of the Asta Galactic Command thank you for your attention. We are now leaving the planes of your existence. May you be blessed by the supreme love and truth of the Cosmos.

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!

On 11 July 1962 this site transmitted the first transatlantic TV signal to a twin station in Pleumeur-Bodou, France via the TELSTAR satellite. The success of TELSTAR and the earth stations, the first built for active satellite communications, illustrated the potential of a future world-wide satellite system to provide communications between continents. The First Transatlantic Transmission of a Television Signal via Satellite was named an IEEE Milestone in July 2002 http://ethw.org/Milestones:First_Transatlantic_Transmission_of_a_Television_Signal_via_Satellite,_1962

Southern Television was the first known victim of television hijacking. On the 26th of November 1977 at around 5:10 pm, an "alien" managed to interrupt the broadcast of the local ITV station Southern Television via the Hannington transmitter. https://en.wikipedia.org/wiki/Southern_Television_broadcast_interruption The voice overrode the UHF audio signal of the early-evening news being read by the late Ivor Mills from ITN. A speaker interrupted transmissions for six minutes and claimed to be a representative of an "Intergalactic Association". Reports of the incident vary, some calling the speaker "Gramaha" or "Vrillon" or "Gillon", others "Asteron". The voice, which was disguised and accompanied by a deep buzzing, broke into the broadcast of the local ITV station Southern Television, overriding the UHF audio signal of the early-evening news being read by Ivor Mills from ITN to warn viewers that "All your weapons of evil must be removed" and "You have but a short time to learn to live together in peace." The interruption ceased shortly after the statement had been delivered, transmissions returning to normal shortly before the end of a Looney Tunes cartoon. Later in the evening, Southern Television apologised for what it described as "a breakthrough in sound" for some viewers. ITN also reported on the incident in its own late-evening Saturday bulletin. The broadcast took over the sound only, leaving the video signal unaltered, aside from some picture distortion.

The high court of Kenya has ordered the government to immediately restore all TV transmissions for three private stations which were shut down on Tuesday pending the hearing of a suit filed by activist Okiya Omtatah. The directive issued by Justice Chacha Mwita also bars the state from interfering with transmission, three days after the communication authority turned off signals for KTN news, citizen TV and NTV.

The video transmission market is mainly supported by the distribution of video content on pay-TV platforms, with TV signals delivered to viewers either directly by satellite or through the head-ends of terrestrial networks. According to the Euroconsult's just-released 'Video Transmission Services over Satellite report an estimated 25,000 TV signals were transmitted by satellite by year-end 2010.

Instruments such as the Analog Arts ST985 (www.analogarts.com), based on the TDR and wave transmission concept, characterize the length, impedance, and other characteristics of a cable. When a signal travels through a cable, it is undisturbed until it encounters an impedance change, and if it encounters an open circuit, all of the wave reflects back to the source. The characteristic impedance of the cable and the load impedance, determine what happens to the signal at the load. A higher load impedance reflects a part of the signal back to the source. There is no reflection when the load impedance is smaller than the impedance of the cable. However, smaller loads cause signal loss. An equal load impedance prevents signal reflection while delivering maximum amount of power to the load. An impedance mismatch can happen whenever the signal medium changes. For example, when the source is connected to the cable or at the load. These mismatches cause reflection and signal loss. In general, the source output impedance, cable characteristic impedance, and load impedance must be made equal for optimal performance. Impedance matching maximizes the power transfer to the load and eliminates signal reflection. A perfect impedance matching transfers half of the source power to the load. When the signal wavelength becomes a significant portion of the cable length, without a proper termination, reflection distorts the signal. The reflected wave changes the amplitude of the signal throughout the cable. At the source, it acts like a load, which if not properly addressed, can damage the signal generator. At certain frequencies, the reflected wave interferes constructively with the signal. The resultant signal is referred to as a standing wave. A TDR consists of a pulse generator, a monitoring instrument device, and a DSP. Generally, in these instruments, the generator outputs a fast transition pulse. This pulse travels to the end of the cable and reflects back. But first it is divided by the voltage divider formed due to the source resistance and the cable impedance. The division factor is then calculated based on which the impedance of the cable is found. The divided signal travels through the cable at a fraction of the speed of light in vacuum. This fraction is referred to as the velocity factor of the cable. For a coax it is about point 67. The time it takes for the signal to reach the end of the cable and reflect to the source, is used to calculate the length of the cable. Impedance matching maximizes the power transfer to the load and prevents reflection. Damaging a cable, by twisting, bending, or kinking, or placing improper signal connectors in the signal path cause an impedance mismatch resulting in reflection, and consequently less than ideal signal handling.

Nikola Tesla gave a public demonstration of the wireless transmission of energy on March 1, 1893. He had created an induction coil to transmit and receive radio signals. Years later while he was preparing to transmit signals at a distance, so was another inventor: Guglielmo Marconi. Marconi transmitted the first transatlantic telegraph but Tesla had secured two radio patents in America. It became a story of fierce competition between two brilliant minds and a debate over who invented radio.
