  2. Sup'R'Mod - Wikipedia

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

    The Sup 'R' Mod II kit has a small printed circuit board, an antenna switch, and a coaxial cable with a ferrite core and RCA connectors.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.

  3. 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. CCIR System L - Wikipedia

    Analog TV systems global map, with System L in magenta. CCIR System L is an analog broadcast television system used in France, Luxembourg, Monaco and Chausey. [1] [2] [3] It was the last system to use positive video modulation and AM sound.

  5. Optical modulator - Wikipedia

    en.wikipedia.org/wiki/Optical_modulator

    An optical modulator is a device which is used to modulate a beam of light. The beam may be carried over free space, or propagated through an optical waveguide ( optical fibre ). Depending on the parameter of a light beam which is manipulated, modulators may be categorized into amplitude modulators, phase modulators, polarization modulators, etc.

  6. DVB-T2 - Wikipedia

    en.wikipedia.org/wiki/DVB-T2

    In March 2006, DVB decided to study options for an upgraded DVB-T standard. In June 2006, a formal study group named TM-T2 (Technical Module on Next Generation DVB-T) was established by the DVB Group to develop an advanced modulation scheme that could be adopted by a second generation digital terrestrial television standard, to be named DVB-T2.

  7. Electro-optic modulator - Wikipedia

    en.wikipedia.org/wiki/Electro-optic_modulator

    An electro-optic modulator (EOM) is an optical device in which a signal-controlled element exhibiting an electro-optic effect is used to modulate a beam of light. The modulation may be imposed on the phase , frequency , amplitude , or polarization of the beam.

  8. Analog passthrough - Wikipedia

    en.wikipedia.org/wiki/Analog_passthrough

    Analog passthrough is a feature found on some digital-to-analog television converter boxes.Boxes without the analog passthrough feature only allow older, analog-only TVs to view digital TV.

  9. Video sender - Wikipedia

    en.wikipedia.org/wiki/Video_sender

    Analogue video senders have the advantage of low manufacturing costs as the audio and video signals are simply modulated onto a carrier at 2.4 GHz or 5.8 GHz.They do, however, have the adverse effect of causing reduced bandwidth to local Wi-Fi networks and, in some cases, Wi-Fi networks can cause picture interference on the video sender signal.
