Some examples of well-known variable-length coding strategies are huffman coding, lempel-ziv coding and arithmetic coding context-adaptive variable length coding (cavlc) is a form of entropy coding used in h264/mpeg-4 avc video. Cavlc (context based adaptive variable length coding) introduction: h264, the latest video compression standard, uses cavlc for encoding the coefficients. This work addresses the watermarking of an entropy coded h264/avc video stream the phrase substitution watermarking is used to imply that the application of the watermark to the stream is accomplished by substituting an original block of bits in the entropy-encoded stream with an alternative block of bits.
