CONSTITUTION: When a recording check key signal is inputted(S10), a microcomputer displays a currently inputted video signal(S12). A monitoring encoder encodes channel video data, and reproduces current video data(S16). A multiplexer transmits multiplexed video data to an MPEG2 encoder(S18). The MPEG2 encoder compresses the video data, while a CPU stores the video data on an HDD(S20-S24). An MPEG2 decoder restores the video data into original data(S28,S30). A switch disconnects the decoder from a demultiplexer while connecting the decoder with a signal detector(S32). The signal detector detects a video synchronous signal to transmit the signal to the microcomputer(S34). The microcomputer decides whether the signal exceeds a reference value(S36).
