Blind Video Watermarking Scheme for Mpeg-4 Videos with Parity Sequences in Transform Domain
High quality video broad casting is of high demand both with DVB-2 (Digital Video Broad casting) and Internet services. But these broadcasted data is distributed without protection. Invisible mode of video watermarking is one of the solutions, here in this paper a novel approach of data embedding scheme is proposed for MPEG-4 videos with different parity check codes and processed in transform domain. A subjective and objective analysis is performed to examine the proposed approach. Experimental results on various videos have shown that LDPC (Low density parity check) code with Gold spreading sequence in transform domain outperforms when compared against the other methods.
