    摘要: Methods and apparatus are provided for unified significance map coding. An apparatus includes a video encoder for encoding transform coefficients for at least a portion of a picture. The transform coefficients are obtained using a plurality of transforms. One or more context sharing maps are generated for the transform coefficients based on a unified rule. The one or more context sharing maps are for providing at least one context that is shared among at least some of the transform coefficients obtained from at least two different ones of the plurality of transforms.

    摘要: Methods and apparatus are provided for encoding and decoding binary sets using adaptive tree selection. In one exemplary encoding method embodiment, picture data is encoded for a block in a picture; in which one of a plurality of trees structures is selected to code a binary set of data for indicating coefficient significance for the block. In another exemplary encoding method embodiment, picture data is encoded for a block in a picture, in which one or more trees are used to encode a binary set of data for indicating coefficient significance for the block, the one or more trees each having a plurality of nodes, at least one of the nodes of the one or more trees being modified responsive to at least one parameter.

    摘要: Methods and apparatus are provided for video encoding and decoding using adaptive geometric partitioning. An apparatus includes an encoder for encoding picture data for a region in a picture using adaptive geometric partitioning, wherein a subset of geometric partitions used to code the picture data for the region is determined responsive to at least one of a distance and an angle. The distance is measured from a defined point within the region to a partition boundary. The angle is measured with respect to at least a line extending from the defined point within the region to the partition boundary.
