发明名称 Audio signal processing circuit and video/audio decoder
摘要 <p>An audio signal processing circuit has a synchronizing pattern detector, an unformatter, a synthesizing filter, an output latch, and a sequence generator. The sequence generator starts to operate the unformatter and the synthesizing filter from the time of the synchronizing pattern in the audio bit stream, and then temporarily stops the operation of the unformatter and the synthesizing filter when a first sample of the audio signal is stored in the output latch. In response to an audio start signal, the sequence generator starts to operate the unformatter and the synthesizing filter again to output an audio signal without a synchronization time error. <IMAGE></p>
