摘要： Apparatus and methods are described for encoding and decoding an enhancement layer. A deblocking filter is applied at the enhancement layer for bit depth scalability. The deblocking filter is adjusted to remove coding artifacts caused by local inverse tone mapping for intra-layer texture prediction for the bit depth scalability. The boundary strength of the deblocking filter is adjusted based on a threshold that, in turn, is based on a difference of inverse tone mapping parameters for a block and an adjacent block.

摘要： Implementations are provided that relate, for example, to view tiling in video encoding and decoding. A particular implementation accesses a video picture that includes multiple pictures combined into a single picture, and accesses additional information indicating how the multiple pictures in the accessed video picture are combined. The accessed information includes spatial interleaving information and sampling information. Another implementation encodes a video picture that includes multiple pictures combined into a single picture, and generates information indicating how the multiple pictures in the accessed video picture are combined. The generated information includes spatial interleaving information and sampling information. A bitstream is formed that includes the encoded video picture and the generated information. Another implementation provides a data structure for transmitting the generated information.
