  • Sound reproducing system and method capable of decoding audio data even in case of failure of detecting syncword
    Patent number: 6363514
    Abstract: A sound reproducing system that decodes audio data in a frame with which detection of a syncword fails, if a syncword included in a subsequent frame is detected, if correctness of bit stream information in the subsequent frame is proved, and if no CRC error is detected (when CRC is included). This makes it possible to solve a problem involved in a conventional system in that when a unit frame without an error check pattern is input and a synchronization detector produces a synchronization detection error signal, unpleasant sound interruption can take place even if the audio data is correct, because the correctness of the audio data cannot be checked, and hence the audio data cannot be decoded in this case.
