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.

摘要： Disclosed are various embodiments for displaying pictures at high speed. In one embodiment, a system includes a buffer for storing parameters associated with a predetermined number of the pictures during a video display period. The system further includes a video decoder for decoding particular ones of the predetermined number of the pictures. The predetermined ones are either reference pictures or pictures that are to be displayed at high speed. The pictures that are displayed in high speed at each display interval have a constant time-lapse between the pictures that are displayed in high speed at the next display interval.

摘要： Presented herein are systems and methods for pause and freeze functions for digital video streams. A particular picture is displayed for a plurality of video display periods. A next picture is displayed at the video display period immediately following the plurality of video display periods, the next picture immediately following the particular picture in a display order. A system clock reference is loaded with a time stamp associated with the next picture when displaying the next picture.
