摘要： A method and system are provided in to perform video encoding operations. An encoder module encodes a current block of pixels by selecting an intra-mode compression or an inter-mode compression based on a type of frame being compressed. The intra-mode compression includes a direction estimation operation based on values of previously reconstructed pixels.

摘要： Systems, devices and methods for performing luma-based chroma ultra prediction are described. Down-sample filters may be applied to luma values of luma pixel positions to generate reconstructed luma values for chroma pixel positions in a prediction unit of an intra frame. The down-sampled reconstructed luma values may then be used to predict chroma values for the chroma pixel positions. In some implementations, a reconstructed luma value of a chroma position may be used to predict that position's chroma value. In other implementations, reconstructed luma values of neighboring chroma pixel positions may be analyzed to adaptively predict a chroma value for a chroma pixel position.

摘要： A video coder includes a forward coder and a reconstruction module determining a motion compensated predicted picture from one or more previously decoded pictures in a multi-picture store. The reconstruction module includes a reference picture predictor that uses only previously decoded pictures to determine one or more predicted reference pictures. The predicted reference picture(s) are used for motion compensated prediction. The reference picture predictor may include optical flow analysis that uses a current decoded picture and that may use one or more previously decoded pictures together with affine motion analysis and image warping to determine at least a portion of at least one of the reference pictures.

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。
