摘要： Methods and apparatus are provided for improved entropy encoding and decoding. An apparatus includes a video encoder 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 having a value greater than or equal to a specified value.

摘要： Various implementations provide filtering for pictures. Several such implementations attempt to reduce artifacts caused by over-filtering in a decoding loop. Certain of these implementations provide multiple loop filters, and select a loop filter based on the result of a deblocking 5 filter. One particular implementation applies a first filter to a picture to produce a filtered picture. A second filter is selected based on a difference between a value of a particular pixel in the filtered picture and a value of a corresponding pixel in the picture. The second filter is applied to the particular pixel in the filtered picture. In another implementation, a signal or signal structure includes 10 an indication of the second filter, an encoding of at least a portion of a picture, and an encoding of at least a portion of a subsequent picture that has been encoded based on the output of the second filter above.

摘要： Methods and apparatus are provided for implicit adaptive motion vector predictor selection for video encoding and decoding. The method encodes an image block using implicit adaptive motion vector predictor selection. The motion vector for encoding the block is predicted by defining a set of motion vector predictor candidates for the block based on a plurality of spatio-temporal neighboring motion vectors; and then selecting from the set a particular motion vector predictor candidate as the motion vector for encoding the bloc. The selection is made responsive to respective values for a fidelity of the spatio-temporal neighboring motion vectors.
