<P>PROBLEM TO BE SOLVED: To provide a method to indicate when the mapping among modes and transform types should be altered for intra and inter prediction. <P>SOLUTION: A bitstream includes coded pictures to obtain data for associated TUs and data for generating a transform tree, a partitioning of coding units (CUs) into prediction units (PUs), and data for obtaining prediction modes or directions associated with each PU. One or more mapping tables are defined, in which each row of each table has an index and a first set of transform types to be used for applying an inverse transformation to the data in TU. The first set of transform types is selected according to an index, and then a second set of transform types is applied as the inverse transformation to the data. The second set of transform types is determined according to the first set of transform types and a transform-toggle flag (ttf) to obtain a reconstructed prediction residual. <P>COPYRIGHT: (C)2013,JPO&INPIT |
