摘要： A hybrid intra-inter bi-predictive (or multi-predictive) coding mode allows both intraframe (intra) (301 in FIG. 5) and interframe (inter) (302 in FIG. 5) predictions to be combined together for hybrid-encoding a current macroblock or a subblock (310 in FIG. 5). Bi-prediction may be used also in I-pictures, combining two intra predictions that use two different intra prediction directions. A video encoder (700) processes data representing a two-dimensional video image which has been produced by a conventional commercially available video camera. The video encoder is adapted to select, for coding a current macroblock, between an intra encoding mode, an P-frame inter encoding mode, a B-frame bi-predictive inter mode, and a hybrid intra-inter bi-predictive encoding mode. A video decoder (800) receives and decodes a data stream that may contain a block/macroblock encoded in accordance with the hybrid intra-inter bi-predictive encoding mode.

摘要： An encoder (10) achieves improved encoding efficiency by initially limiting consideration of the potential modes (block sizes) to a prescribed sub-set and by performing mode estimation jointly with mode decision-making. An initial sub-set of modes is considered and an estimation of the motion for each block in the sub-set is made to establish a best motion vector. A distortion measure is also made for each sub-set. From the distortion measure, a determination is made whether or not to estimate the motion for other block sizes. If not, then an encoding mode is chosen in accordance with the estimated motion. In this way, motion estimation on all possible block sizes need not be undertaken.
摘要翻译：编码器（10）通过首先将潜在模式（块大小）考虑到规定的子集并且通过与模式决策联合执行模式估计来实现改进的编码效率。考虑模式的初始子集，并且对子集中每个块的运动进行估计以建立最佳运动矢量。还对每个子集进行失真测量。从失真测量中，确定是否估计其他块大小的运动。如果不是，则根据估计的运动来选择编码模式。以这种方式，不需要对所有可能的块大小进行运动估计。

摘要： The present invention provides a method and apparatus for encoding video content into a novel temporal layered coding structure. In one embodiment of the present invention, a plurality of sub-sequence layers are defined in a layer hierarchy in accordance with the present invention. A plurality of images within a sub-sequence of a group of images are selectively assigned to a respective one of the sub-sequence layers. A grouping of images contained in any sequential combination of sub-sequence layers that includes a hierarchically lowest of the sub-sequence layers results in a group of images that temporally are substantially evenly spaced. A related method and apparatus for decoding the temporally layered video content are also disclosed.
