摘要

The circuit generates the initial screen of blue background or video in memory when playing a VCR in stop mode. It includes a demodulator (20) for demodulating the signal from a video head (10), a storing section (30) for storing the signal from the demodulator (20), a blue background generator (71), and a signal absence detector (40) for detecting the absence of signal.
