摘要： An embodiment method of transcoding a macroblock coded in one of a Skip mode and a Direct mode includes recording a first reference frame index and a first motion vector corresponding to the macroblock during a decoding process and deriving a second reference frame index and a second motion vector corresponding to the macroblock during an encoding process. The method further includes comparing the first reference frame index to the second reference frame index and the first motion vector to the second motion vector during the encoding process. If the comparing achieves a predetermined criteria, the Skip mode and the Direct mode are reused to encode the macroblock during the encoding process.

摘要： At least one implementation provides a transcoder for merging two AVC (including, for example, the SVC annex) bitstreams. Various implementations provide advantages such as, for example, avoiding full decoding of at least one bitstream and/or avoiding motion compensation during the coding of an enhancement layer block. One particular implementation includes accessing a first and a second AVC encoding of a sequence of data. The second AVC encoding differs from the first AVC encoding in quality. The particular implementation further includes merging the first AVC encoding and the second AVC encoding into a third AVC encoding that uses the SVC extension of AVC. The merging is performed such that the first and second AVC encodings occupy different layers, and the first layer is a reference layer for the second layer.

摘要： Various disclosed implementations allow a flexible amount of redundancy to be used in coding. In one general implementation, information is accessed for determining which of multiple encodings of at least a portion of a data object to send over a channel. A set of multiple encodings is determined for sending over the channel, with the set including at least one and possibly more of the multiple encodings, and the number of encodings in the set being based on the accessed information. In a more particular implementation, the redundant slice feature of the H.264/AVC coding standard is used, and a variable number of redundant slices is transmitted for any given picture based on current channel conditions.
