2. RF modulator - Wikipedia

   en.wikipedia.org/wiki/RF_modulator

   The modulator is then programmed to broadcast the signals on a certain frequency. That RF broadcast is then received by the connected TV. When the TV is tuned to the programmed channel, the video and audio signal of the source device is accessed. RF modulation can become difficult in a CATV system. High pass, low pass, and notch filters must be ...

4. Sup'R'Mod - Wikipedia

   en.wikipedia.org/wiki/Sup'R'Mod

   Composite video is received by the circuit board through a short cable terminating in a Molex connector, which plugs into a header on the Apple II motherboard. Input can also be provided through an RCA connector. The output of the RF modulator goes out through a coaxial cable to the antenna switch. [5] [6]

   This may then be converted to FM RF with an RF modulator that generates the proper carrier (often for channel 3 or 4 in North America, channel 36 in Europe). Sometimes this modulator is built into the product (such as video game consoles, VCRs, or the Atari , Commodore 64 , or TRS-80 CoCo home-computers), is an external unit powered by the ...

6. Digital television adapter - Wikipedia

   en.wikipedia.org/wiki/Digital_television_adapter

   A converter box takes the digital signal from the antenna and outputs composite video (for SD TVs) or HDMI (for HD TVs). A RF/antenna output, if present on a converter box, is usually just a passthrough ("LOOP OUT" which does not provide the box's output signal, but only provides the raw antenna input signal to watch analog channels via a TV ...

7. Video modulation - Wikipedia

   en.wikipedia.org/wiki/Video_modulation

   Video signals are usually encoded into binary digit (0, 1) or seven digit pulse-code modulation (PCM), which is a method used to digitally represent original video signal. . The video signal converted to binary digit PCM at the point of origin can be then transmitted over existing telephone cable or wire directly to the destination
