Abstract
A receiver is constructed so that it detects a short-break of a digital broadcasting wave by the absence of a synchronizing code or by a transmission control signal multiplexed with the broadcasting wave and, according to the short-break detection signal, holds data and state information (program arrangement, and reference time information) obtained by an antenna and converter (1), tuner and digital decoding portion (2), an error correction code decoding portion (3), a stream multiplexed signal separating portion (4), an audio/video decoding portion (5) and the other components and performs a process for optimally changing characteristics of closed loops for establishing synchronization.
