PROBLEM TO BE SOLVED: To provide a method and apparatus for encoding and decoding binary sets using adaptive tree selection.SOLUTION: In an encoding method, picture data is encoded for a block in a picture, in which one of a plurality of tree structures is selected to code 525 a binary set of data indicating coefficient significance for the block. Picture data is encoded for a block in a picture, in which one or more trees may be used to encode a binary set of data 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 in response to at least one parameter. |
