  • Time-base corrector circuit capable of adding color burst signal to output signal based on kind of input video signal
    Patent number: 5926602
    Abstract: A memory controller which controls writing/reading operation to/from a memory in a TBC circuit prohibits writing operation to the memory circuit in response to an activation of a frame grab signal after an A/D converted video signal for one frame is stored in the memory circuit. A color demodulator detects whether or not a color burst signal is added to a video signal input at the time at which the frame grab signal is activated, and the result of detection is held in a flip-flop circuit. In response to a signal from the flip-flop circuit, a color burst signal is added to a video signal output from an encoder.
