    摘要: Presented herein is a system and method for reducing the total size of the frame buffer portion of a decoding circuit. The reduction in size is possible because first portions of B-pictures are displayed while second portions occurring later in the raster order are decoded. The foregoing allows the second portions occurring later in the raster order to overwrite third portions of the picture that have already been displayed. As a result, the frame buffer for providing the frame from a decoder to the display engine need only store the portion that is being displayed and the portion that is being decoded.

    摘要: A system and method that support display of video fields using related data encoded in data structures. Each data structure is associated with one video field and contains all the information associated with the display of the video field. The data structure is encoded with the video field that is displayed exactly one field prior to the field associated with the data structure. In an embodiment of the present invention, the data structure contains all the information associated with the display of a video field, regardless of whether certain data changes from one field to the next.

    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.
