Abstract: Presented herein are a system, method, and apparatus for audio and video synchronization. In one embodiment, there is presented a method for displaying audio data and video data. The method comprises examining a plurality of portions of the audio data, where each of said plurality of portions of audio data is associated with a time stamp; examining a plurality of portions of the video data, where each of said plurality of portions of the video data is associated with a time stamp; decoding one of the portions of the video data; and decoding one of the portions of the audio data while decoding the one of the portions of the video data. The difference between the time stamp associated with the one of the portions of the video data and the time stamp associated with the one of the portions of the audio data is within a certain margin of error from a predetermined offset.

Abstract: Error concealment for motion picture expert group (MPEG) decoding with personal video recording functionality. Error concealment of MPEG data may take place within various components within playback, recording, reading and writing data systems. The error concealment may be provided within existing systems whose components may not be capable of accommodating errors within MPEG data. In certain embodiments, the available data that contain no errors is maximized to conceal those portions of the data that do include errors.

Abstract: 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.

Abstract translation: 这里提出的是用于减小解码电路的帧缓冲器部分的总大小的系统和方法。 尺寸的减小是可能的，因为B图像的第一部分被显示，而以光栅顺序发生的第二部分被解码。 上述允许以光栅顺序稍后出现的第二部分覆盖已经显示的图片的第三部分。 结果，用于将帧从解码器提供给显示引擎的帧缓冲器仅需要存储正被显示的部分和正被解码的部分。
