Abstract
An apparatus and a method for an efficient audio/video (AV) synchronization are provided. The apparatus includes a parser, a frame memory, a video start code (VSC) detector and a video decoder. The parser is used for analyzing a packetized elementary stream (PES) and outputting a video stream, an address information and at least one time stamp, in which the video stream includes a frame and at least one VSC corresponding to the frame. The frame memory is used for temporarily storing the video stream according to the address information. The VSC detector is used for retrieving the VSC of the video stream. The video decoder is used for selecting the frame from the frame memory according to the VSC and the address information provided by the VSC detector.
