Apparatus and method for synchronizing video and audio MPEG streams in a video playback device |
摘要 |
There is disclosed an MPEG decoder comprising: 1) a packetized elementary stream (PES) interface for receiving a plurality of packetized elementary streams associated with a single video program; 2) a presentation time stamp (PTS) detection circuit for detecting presentation time stamps in the packetized elementary streams and extracting the presentation time stamps therefrom; and 3) a selection circuit for selecting presentation time stamps associated with a first one of the plurality of packetized elementary streams and transmitting the selected presentation time stamps to a clock generation circuit, wherein the clock generation circuit generates a first reference clock signal used by a first decoder to decode the first packetized elementary stream. The clock generation circuit further generates a second reference clock signal synchronized to the first reference clock signal, wherein the second reference clock signal is used by a second decoder to decode a second packetized elementary stream in synchronization with the first packetized elementary stream.
