A digital sound broadcasting receiver and method receives a radio wave from a digital sound broadcasting station, demodulates the radio wave into baseband signals at a tuner, subjects the signals to demodulation, performs error detection and error correction at signal processors to obtain digital data, and inputs the digital data into an audio circuit to obtain audio or data output. A CRC error rate detector 13 for a fast information channel (FIC) for APC pseudo lock releasing action on demodulating the signals is arranged to determine, based on the possibility of an error rate of an error-detecting code (CRC) of the FIC, whether an APC pseudo lock state occurs, and to control releasing action for the APC pseudo lock state.
A digital sound broadcasting receiver comprising:
An automatic phase controlling method in a digital sound broadcasting receiver which includes synchronization controlling means for automatic phase controlling a received, demodulated signal based on a phase of the received, demodulated signal for determining whether a current phase lock state is proper, and for releasing the current phase lock state and shifting to a new phase lock state when determining that the current phase lock state is improper, comprising the steps of:
