Abstract
A method and apparatus for coding of syntax elements are disclosed to allow prediction units in P and B slices to share the same syntax coding table. In one embodiment according to the present invention, the method and apparatus coding of syntax elements selectively apply a syntax coding table to encode or decode the syntax element associated with the partition mode of a coding unit of a picture region according to the slice type of the picture region. A first syntax coding table is used to process the syntax element if the slice type is an I mode and a second syntax coding table is used to process the syntax element if the slice type is not an I mode.
Claims16
A method for coding of syntax elements, the method comprising:
- receiving one or more syntax elements for a block in a picture region, wherein said one or more syntax elements are associated with a partition mode of the block and wherein the picture region is associated with a picture-region type and the picture-region type of the picture region corresponds to an I type, a P type or a B type;
- processing said one or more syntax elements according to a first syntax coding table, if the picture-region type is the I type;
- and
- processing said one or more syntax elements according to a second syntax coding table, if the picture-region type is the P type or the B type.
An apparatus for coding of syntax elements, the apparatus comprising:
- means for receiving one or more syntax elements for a block in a picture region, wherein said one or more syntax elements are associated with a partition mode of the block and wherein the picture region is associated with a picture-region type and the picture-region type of the picture region corresponds to an I type, a P type or a B type;
- means for means for processing said one or more syntax elements according to a first syntax coding table, if the picture-region type is the I type;
- and
- means for processing said one or more syntax elements according to a second syntax coding table, if the picture-region type is the P type or the B type.
