<p>An apparatus and method for synchronizing audio and video signals wherein the motion of a picture is detected in case of occurring timing difference between the audio and video signals and subsequently a threshold is adjusted in association with the detected motion of the picture, thereby controlling the mute audio signal. An apparatus for synchronizing audio/video comprises an inverse transport processor for outputting compressed audio and video signals and further detecting a motion of picture to output a variable associated with the motion of picture, a video decompressor for decompressing the compressed video signal from the inverse transport processor, an audio decompressor for decompressing the compressed audio signal from the inverse transport processor, a microprocessor for processing the audio and video signals outputted from the audio decompressor and the video decompressor respectively to generate a synchronization error signal, and a threshold detector for generating audio muting signal, responsive to the variable from the inverse transport processor and the synchronization error signal from the microprocessor.</p> |
