    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.
