摘要： There are provided methods and apparatus for constrained prediction for reduced resolution update mode and complexity scalability in video encoders and decoders. A scalable complexity video encoder includes an encoder for encoding a block in a particular picture in the video sequence by generating an intra mode prediction for the block using a constrained intra prediction process that reduces artifacts for both low and high resolutions in a reduced resolution update mode when the particular picture is eventually decoded. The constrained intra prediction process reduces the artifacts by prohibiting the use of particular prediction modes associated with the introduction of the artifacts in the reduced resolution update mode.

摘要： A hybrid intra-inter bi-predictive (or multi-predictive) coding mode allows both intraframe (intra) and interframe (inter) predictions to be combined together for hybrid-encoding a current macroblock or a subblock Bi-prediction may be used also in I-pictures, combining two intra predictions that use two different intra prediction directions. A video encoder 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： A method and system reduces the spatial resolution of a compressed bitstream of a sequence of frames of a video signal by first decoding the frames, and storing the decoded frames in a first frame buffer. While performing the decoding, motion compensating is performed with full resolution motion vectors of the stored decoded frames. The decoded frames are then down-sampled to a reduced resolution, and stored in a second frame buffer. The reduced resolution frames are partially encoded to produce a reduced resolution compressed bitstream of the video. While performing the partial encoding, motion compensation is performed with reduced resolution motion vectors of the stored reduced resolution frames.
