Abstract
Scrambled video and audio signals of programs are transmitted from a transmitting system via a communication satellite to a receiving system. The audio signal contains channel, start/end time, and standard time information of the programs. The receiving system has a calendar for generating time information which is corrected according to the standard time information. Desired programs can automatically be recorded by a video tape recorder connected to the receiving system, based on the channel and start/end time information which is displayed. Any received programs which the user of the receiving system does not want to record can be canceled simply by pushing cancel keys.
