METHOD AND APPARATUS FOR UNIFICATION OF SIGNIFICANCE MAP CONTEXT SELECTION

摘要

A method and apparatus for significance map coding for 4×4 TUs (transform units) and 8×8 TUs of video data are disclosed. The method comprises receiving at least one context selection table for a first TU associated with a first color component and generating a derived context selection table for a second TU associated with a second color component from said at least one context selection table. The first TU has a first size comprising of 4×4 and 8×8. The second TU has a second size comprising of 4×4 and 8×8. The second size is different from the first size, the second color component is different from the first color component, or both the second size is different from the first size and the second color component is different from the first color component. The derived context selection table is then used for significance map processing of the second TU.

1. A method of significance map coding for TUs (transform units) of video data using context selection tables, the method comprising:
receiving at least one context selection table for a first TU associated with a first color component, wherein the first TU has a first size selected from a group consisting of 4×4 and 8×8; generating a derived context selection table for a second TU associated with a second color component from said at least one context selection table, wherein the second TU has a second size selected from the group consisting of 4×4 and 8×8, wherein the second size is different from the first size, the second color component is different from the first color component, or both the second size is different from the first size and the second color component is different from the first color component; and providing the derived context selection table for significance map coding processing of the second TU.
