Abstract:
1. A video demodulation device configured to demodulate an RF signal resulting from analog modulation of a composite video, blanking, and sync signal (a CVBS signal) including a horizontal synchronizing signal, and to reproduce the CVBS signal by digital processing, the device comprising: a tuner configured to receive as input the RF signal resulting from analog modulation, and to output an analog IF signal; and a demodulator configured to receive as input the analog IF signal, and to demodulate the CVBS signal, wherein the demodulator includes the synchronization corrector outputs, as the CVBS signal, a composite signal comprising the luminance component and a color component included in the gain adjustment result when the composite signal is smaller than the reference value, or the reference value when the composite signal is equal to or greater than the reference value.
