TV Modul½±tor
This circuit uses an MC1373 to form a TV video modulator. The coil and capacitor connected between pins 1 and 2 should be selected to have a parallel resonance at the carrier frequency of the desired TV channel. The values...
Combining the Composite Sync to the Green Signal
In certain video applications, signal sources provide RGB signals along with a composite sync signal. The RGB signals do not include video sync. On the receiving end, some budget video decoders lack a separate composite sync input; they only accept...
Conditioning A/V Signals for RF Modulation
As display devices transition to digital video, they still incorporate the legacy of RF-modulated analog TV output. In the United States, this output is defined by the National Television Standards Committee (NTSC) and is also utilized in security applications and...
YUV/YCbCr to RGB converter
The device functions as a video recorder, DVD player, and TV game console, featuring a component video output. The component video signal resembles an RGB video signal; however, it is incompatible with RGB monitors.
The device's component video output is designed...
Video Fader Circuit
Fading a video signal cannot be achieved merely by attenuating the composite signal, as this may cause the synchronization signal to fall below an unacceptable level.
To effectively fade a video signal while maintaining the integrity of the synchronization components,...
Video-Out Coupling
To connect a video signal to multiple destinations, a distribution amplifier is required to match the 75-ohm video cable. This amplifier terminates the incoming cable at 75 ohms and provides several outputs, each maintaining a 75-ohm output impedance. Typically, this...
Picture-fixer-inverter
The circuit accepts a video signal, separates the sync pulses, inverts the video, and integrates new video with the existing sync pulses. The video signal is input through J1 and processed by a clamping circuit comprising C1, D1, D2, D3,...
