摘要： A method detects blocks that are to be indicated as skipped at an earlier stage of the encoding process, than would be the case with other implementations of the ITU H.263 and H.264 standards. The method includes transforming 4null4 blocks in the macro blocks having a skip vector of zero with a binary-transform function. The blocks having values of the four uppermost left binary-transform coefficients less than a predefined threshold, are defined as skipped, thus, minimizing the need for computationally demanding block transformation or quantization.

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.
摘要翻译：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。

摘要： A nullpredictive motion estimatornull operates by conducting one or more stages of a multi-stage motion vector (MV) search. A first stage involves performing a background detection process for determining possible MVs. In a second stage, candidate MVs are determined in spatial and temporal neighborhoods. Finally, in a third stage, candidate MVs are determined through MV refinement or pattern searching. Reliability of motion estimation results is evaluated at each stage for determining whether to proceed to the next stage. By gradually enlarging the search pool and advancing the search to the next stage only when the reliability of current stage results are unsatisfactory, the predictive motion estimator successfully balances motion vector search complexity and reliability of motion estimation. Further, for ensuring flexibility in adapting to video sequences of various characteristics, the predictive motion estimator derives search parameters for each stage from prior stage motion estimation results, rather than using preset parameters.
摘要翻译： “预测运动估计器”通过进行多级运动矢量（MV）搜索的一个或多个阶段来操作。第一阶段涉及执行用于确定可能的MV的背景检测处理。在第二阶段中，候选MV在空间和时间邻域中被确定。最后，在第三阶段，通过MV细化或模式搜索来确定候选MV。在每个阶段评估运动估计结果的可靠性，以确定是否进入下一阶段。只有当当前阶段结果的可靠性不能令人满意的情况下，通过逐渐扩大搜索池并将搜索推进到下一阶段，预测运动估计器成功地平衡了运动矢量搜索的复杂度和运动估计的可靠性。此外，为了确保适应各种特征的视频序列的灵活性，预测运动估计器从前级运动估计结果中导出每一级的搜索参数，而不是使用预设参数。

摘要： In a method of synchronizing first and second data streams, the first data stream acting as a reference stream, elements of the first data stream are displayed along a time line on a display device. Containers for elements of the second data stream are displayed on the display device alongside the elements of the first data stream. The containers are interactively displaced on the display device relative to the elements of the first data stream to align the containers with cue elements in the first data stream. Synchronization markers are generated for the aligned displayable elements relative to the first data stream.

摘要： A method for handling video bitstream errors in a multimedia gateway device wherein a gateway device detects errors in the incoming video bitstream and sends a signal to the originating device to refresh the bitstream without need of error detection from an end terminating device. When the terminating device signals for the video bitstream to be refreshed, the gateway locally generates and transmits an appropriate refresh frame. The invention allows the gateway to handle errors for devices such as streaming and message servers that have no built-in error handling.
