Abstract :
In this article an extension of the watermarking scheme, based on key sequence, proposed by Lin et al. is presented. This new scheme is designed taking into account the temporal modifications of the MPEG-2, MPEG-4 part 2 and MPEG4 Part 10 compressions. Besides the redundancy control of Lin is modified and the characteristics extraction process is improved. In this way, a better performance, up to 40% in the BCR (bit correct ratio) measure is gained. Experimental results show that the proposed scheme achieves a better performance against MPEG video compressions than Lin´s scheme.
