CONTEXT-BASED ADAPTIVE BINARY ARITHMETIC CODING (CABAC) VIDEO STREAM COMPLIANCE |
摘要 |
A method of providing CABAC compliant changes such as watermarks comprises accessing encoded data such as video which comprise at least two blocks; creating or accessing a list of changes to the encoded data that include a direct change to a block; determining motion character or motion vector differential of non-immediate block, non-immediate blocks being adjacent to an immediate block that are immediately adjacent to the block; determining change to the immediate block based on original motion character of the block and the non-immediate block and the motion character of the block that would result from the application of the change; storing the change to the list if the change does not cause a difference to the immediate block; and evaluating other potential changes if other potential changes are available, wherein the other potential changes are subjected to the same process steps as the direct change.
