Patent ID: 7469011

Claim:
A method comprising: receiving encoded information for transform coefficients of blocks; and decoding the encoded information, including decoding at least some of the encoded information in an escape mode for which plural codes have sizes that are signaled on a sub-frame basis, wherein the sizes are signaled for a first use of the escape mode in a sub-frame unit but not for a second or further subsequent use of the escape mode in the sub-frame unit, wherein the sizes comprise a run code size and a level code size, and wherein the decoding includes: for the first use of the escape mode in the sub-frame unit but not for the second or further subsequent use of the escape mode in the sub-frame unit, decoding the run code size from a run code size value signaled at block level, and decoding the level code size from a level code size value signaled at block level, for each of the first use and the second or further subsequent use of the escape mode in the sub-frame unit, decoding a run value from a run code of the plural codes, the run code having the run code size, and decoding a level value from a level code of the plural codes, the level code having the level code size.
