ABSTRACT:
A broadcast reception apparatus can detect a changed reception channel without using an extra memory. A signal from an antenna (1) is supplied to a tuner (2), and the tuner (2) is connected with a reception channel preset device (3) and a channel setting device (4). A signal received by the tuner (2) is supplied to a PDC decoder (6) and a decoded television program ID is supplied to a control microcomputer (7). A network code in the television program ID is supplied to a comparator (72), and a network code provided when LUF="1" is detected is supplied to a memory (73). Compared results are supplied to a controller (74) which sequentially outputs a channel selection control signal to the channel setting device (4) if the compared results do not agree. If the compared results agree, a signal representing the reception channel provided at that time is supplied to a television program reserve circuit (71). A signal from the television program reserve circuit (71) is supplied to a recording circuit (8), thereby a video signal from the tuner (2) or the like being recorded.
