  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 ...

    Modulator and antenna switch The Sup 'R' Mod II is an RF modulator which was sold by M&R Enterprises in the late 1970s and early 1980s. It connects computers and other devices with composite video outputs, to a television.

  4. Passthrough (electronics) - Wikipedia

    en.wikipedia.org/wiki/Passthrough_(electronics)

    Analog passthrough (for digital TV) Sega 32X (passthrough for Sega Genesis video games) VCRs, DVD recorders, etc. act as a "pass-through" for composite video and S-video, though sometimes they act as an RF modulator for use on Channel 3. Tape monitor features allow an AV receiver (sometime the recording device itself) to act as a "pass-through ...

  5. 8VSB - Wikipedia

    en.wikipedia.org/wiki/8VSB

    Vestigial sideband modulation (VSB) is a modulation method which attempts to eliminate the spectral redundancy of pulse-amplitude modulation (PAM) signals. Modulating a carrier by a real-valued data sequence results in a sum and a difference frequency, resulting in two symmetrical carrier side-bands.

  6. SV-328 - Wikipedia

    en.wikipedia.org/wiki/SV-328

    The standard ports of a SV-318 / SV-328 support only a few peripherals such as the SV-903 tape drive, a CVBS monitor (or external RF modulator for TV), and two joysticks. However the Super Expander edge connector offered more options: [5] SV-803 Memory expansion card, 16 KB; SV-807 Memory expansion card, 64 KB; SV-805 RS-232 card

  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

  8. NICAM - Wikipedia

    en.wikipedia.org/wiki/NICAM

    Many VCRs later included high quality stereo audio recording as an additional feature, in which the incoming high quality stereo audio source (typically FM radio or NICAM TV) was frequency modulated and then recorded, in addition to the usual audio and video VCR tracks, using the same high-bandwidth helical scanning technique used for the video ...

  9. Amiga video connector - Wikipedia

    en.wikipedia.org/wiki/Amiga_video_connector

    The Amiga 520 adapter allowed for RF modulated and composite video output, to be connected to a TV Alternatively, Commodore sold an adapter (the A520 ), that attached to the Amiga video connector and provided composite and RF outputs appropriate to the region in which it was sold.
