摘要： Methods and apparatus are provided for improved entropy encoding and decoding. An apparatus includes a video encoder (200) for encoding at least a block in a picture by transforming a residue of the block to obtain transform coefficients, quantizing the transform coefficients to obtain quantized transform coefficients, and entropy coding the quantized transform coefficients. The quantized transform coefficients are encoded using a flag to indicate that a current one of the quantized transform coefficients being processed is a last non-zero coefficient for the block hiving a value greater than or equal to a specified value.

摘要： Methods and apparatus for a classification-based loop filter are provided. An encoding method encodes an input picture by transforming and quantizing a residue of the input picture to obtain quantized transform coefficients. Then inverse quantizing and inverse transforming the quantized transform coefficients to obtain a reconstructed version of the residue. A reconstructed version of the input picture is obtained by combining at least one reference picture with the reconstructed version of the residue. Pixels in the reconstructed version of the input picture are classified within a respective one of a plurality of categories responsive to local geometric characteristics. Pixels are selected for filtering responsive to a corresponding classification of the pixels with respect to the plurality of categories.

摘要： Methods and apparatus are provided for embedded quantization parameter adjustment in video encoding and decoding. An apparatus includes an encoder for encoding picture data for at least a block in a picture. A quantization parameter, applied to one or more transform coefficients obtained by transforming a difference between an original version of the block and at least one reference block, is derived from reconstructed data corresponding to at least the block.
