Automatic video tape running mode setting circuit for programmed recordings
First Claim
1. An automatic video tape running mode setting circuit for programmed recordings, comprising:
- programmed recording time memory means for memorizing and outputting programmed recording start and end times successively for a plurality of programs set by a user;
a programmed recording time detector for providing output signals by detecting the total programmed recording time for all the programs by subtracting the start time from the end time outputted from said programmed recording time memory means for each of the programs to calculate each programmed recording time, and by adding all such programmed recording times to obtain the total programmed recording time for all the programs;
a recording capacity detector for detecting recording capacity of the video tape, said video tape being housed in a cassette loaded in a deck;
a recording capacity time base data generator for generating time base data corresponding to the recording capacity detected by said recording capacity detector; and
a running mode signal generator for generating and transmitting a video tape running mode signal to a microcomputer, said microcomputer controlling the operation of the whole system by comparing the output signals of the programmed recording time detector and the recording capacity time base data generator.
