摘要： Described herein is a system and method for audio visual synchronization. The picture are displayed by receiving an identifier, said identifier associated with a frame buffer storing a picture; extracting a presentation time stamp associated with the picture, wherein the picture is associated with a time stamp; comparing a local time clock value to the presentation time stamp; determining that the picture is mature for presentation if the presentation time stamp exceeds the local time clock value by less than a first predetermined threshold; and determining that the picture is mature for presentation if the local time clock value exceeds the presentation time stamp by less than a second predetermined threshold.
