A Secure Digital Watermarking Scheme for MPEG-2 Video Copyright Protection

Video watermarking is an important method of protecting the intellectual property copyright of the video media. It allows embedding of copyright information into the video pictures. In this paper a new hybrid approach of digital video watermarking scheme with an Error Correcting Code (ECC) is proposed. This watermarking scheme maximizes the watermark payload while minimizing the perceptual degradation of video quality caused by the embedded watermark by means of an appropriate choice of embedding position. Two hybrid error correcting codes, BCH(31,8) and Turbo (3,1) with repetition code were implemented and compared. We found that the hybrid approach of BCH(31,8) with repetition code achieved higher error correcting capability than Turbo (3,1) with repetition code under the simulated noise tests.
