Broadcast signal receiver and tape recorder and, method of detecting additional information channel |
摘要 |
The video cassette recorder selects channels in succession, determines the presence or absence of additional information included in the broadcast signal for the selected channel, and stores the selected channel regarded as a reception channel for the additional information when detecting the presence of the additional information in the broadcast signal. Further, the recorder extracts station identification information included in the broadcast signal for the selected channel, provides a VCR Plus guide channel corresponding to the station identified by the station identification information, and stores in its memory the relationship between the selected channel and the VCR Plus guide channel. Moreover, the recorder compares a remaining recording time available with the program continuation time extracted from the broadcast signal, and controls a recording speed mode appropriately based on the comparison.
