    摘要： Detection of errors in a video stream occurs by calculating an error detection code, such as a Cyclic Redundancy Check (CRC) code over a group of not more than N macroblocks in a slice of the stream prior and after transmission, where N is an integer greater than zero but less than the total number of macroblocks in the slice. A comparison of the error detection codes reveals whether any errors exist in the group of macroblocks. If the group has no errors, normal decoding occurs. If the macroblock group has an error, then the macroblock group, and the remaining blocks in the slice undergo error concealment.

    摘要： Methods and apparatus are provided for texture compression using patch-based sampling texture synthesis. An apparatus includes an encoder for encoding texture for a picture by synthesizing the texture. The encoder performs texture synthesis using a patch-based sampling method, thus determining “displacement vectors” indicating positions of patches in an input sample texture which are to be synthesized. At the encoder, both the input sample texture and information representing the “displacement vectors” are coded. At the decoder, the new patches are generated by directly using the “displacement vectors”.

    摘要： An encoder and corresponding method are disclosed for performing video rate control to meet network traffic model restrictions, including pre-encoding the sequence of pictures for each of a plurality of quantization parameter values, selecting for each picture of the sequence one of the plurality of quantization parameter values responsive to the quantization parameter values and bitrate operating points of the neighboring pictures in the sliding time window, and encoding each picture of the sequence using the quantization parameter value selected for that picture.
