METHOD AND DEVICE PRINT WATERMARK ON CODE VARIABLE EXTENSION DATA, CONTINUOUS FLOW OF CODE VARIABLE EXTENSION DATA AND LEGAL MEDIA BY PROCESSOR

摘要

method and device print watermark on variable length encoded data, continuous stream of variable length encoded data, and processor readable media Various implementations are provided, for example, for data determination with watermark printing, execution watermark printing, and watermark printing processing. At least one implementation prints the watermark in the avc-pattern bitstream using cavlc-entropy coding. Watermarked data can be determined at a preprocessing stage and stored for later use in a watermarked bit stream. a method accesses (810) the variable length coded data including an information coding identifying an actual reference used for predictive coding of an image. Information coding has a particular value. the method determines (830) an alternative value that is different from the particular value so that the alternative value consists of an alternative information coding identifying a reference other than the current reference. The alternate value is for use in watermark printing of variable length encoded data.
