摘要:
Video signals received on TV channels are recorded and reproduced with time-division compression and decompression to and from a storage medium (63) to allow the video signals to be reproduced while the signals are being recorded. A channel-switching signal is generated when a first TV channel is switched to a second TV channel. Recording of a video signal received on the second TV channel is inhibited for a specific period until a normal video signal received on the second TV channel is gained after the output of the channel-switching signal. Recording of the video signal received on the second TV channel is allowed when the specific period elapses.
摘要:
An information signal is received, which includes a main information content signal carrying the contents of the information, a CM portion signal carrying commercial messages (CM) and an information mode discriminating signal used for discriminating information modes of the main information content signal and the CM signal from each other according to the contents. A video signal is encoded per plurality of several video frames, the video signal including the main information content signal and the CM portion signal. The encoded video signal is recorded in a storage medium. The video signal is reproduced, during the recording, from the storage medium while the CM portion signal is skipped. The received main information content signal and CM portion signal are recorded in the storage medium. The information mode discriminating signal is recorded in the storage medium or another temporary storage medium. At least the information mode discriminating signal is retrieved from the storage medium or the temporary storage medium. Locations of the recorded CM portion signal in the storage medium is detected based on information mode corresponding to the CM portion signal among a plurality of information modes discriminated by means of the information mode discriminating signal. The main information content signal is reproduced from the storage medium while skipping the CM portion signal based on recorded positions of the video signal encoded per plurality of video frames corresponding to the detected locations of the recorded CM portion signal.
