DIGITAL BROADCAST TRANSMITTER, DIGITAL BROADCAST RECEIVER, DIGITAL BROADCAST TRANSMISSION METHOD, DIGITAL BROADCAST RECEPTION METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a digital broadcast transmitter that reduces inconvenience in a service served for a digital broadcast receiver for receiving program information and to provide the digital broadcast receiver. SOLUTION: When extension of program broadcasting is determined while the digital broadcast receiver 200 makes video recording, the digital broadcast receiver 200 receives a maximum extension time of the program from the digital broadcast transmitter (not shown) and a control section 207 decreases a tape speed of a video recorder 250 via a video recording control I/F 214 on the basis of the maximum extension time and a tape residual amount, then the digital broadcast receiver can reduce occurrence of trouble such that the program cannot be video-recorded to the end because of tape deficiency. Further, in waiting for start of an object program whose broadcast start time is not determined, the digital broadcast receiver receives a confirmed schedule broadcast start time from the digital broadcast transmitter (not shown) and temporarily interrupts the power supply until the confirmed time comes under the control of a timer section 211 so as to reduce the power consumption required for awaiting the object program start.
