/ CABAC/AVC COMPLIANT WATERMARKING OF SYNTAX ELEMENTS IN COMPRESSED VIDEO

摘要

method is currently having a syntax element, and, watermarks for the current block of the step, and the video data to access a list of the watermark for the step, the encoded video data to access the encoded video data determining syntax elements of the block, on the basis of the difference in the syntax elements between the current block with the current block and the watermark, the method comprising removing watermarks that result in artifacts (artifact) visible, the removing step generating a filtered list of watermark that can be accommodated by, and a removal step. Method of the present block and the step of determining coding variable ranges for the current block with watermarks from the list, and comparing the coding variable ranges for the current block with the current block and a watermark from the list, and the current block the step of filtering out watermarks that yield coding variable ranges for coding variable ranges may be further included. In addition, the method is a current block, and determining a bit length of the current block with watermarks from the list, the current block and the step of comparing the bit length of the current block with watermarks from the list, and the bit length of the present block for calculating the bit lengths are not the same and may include the step of filtering the watermark. ;
