摘要:
Apparatus and methods of using content information for encoding multimedia data are described. A method of processing multimedia data includes A method of processing multimedia data, including obtaining content information of multimedia data, and encoding the multimedia data to form an encoded bitstream, said encoding comprising inserting at least one redundant block of intra-coded data into the encoded bitstream based on the content information. In some aspects, the encoding comprises encoding the multimedia data into a base layer and an enhancement layer, and wherein the intra-coded data is encoded using the quantization parameter for the base layer. In other aspects, the intra-coded data is encoded using the quantization parameter for the enhancement layer.
