Abstract :
A method of design and implementation of watermarking copyright protection program based on MPEG-4 bit stream is proposed in this paper. The selected DCT coefficients are changed little to meet the specific relationship and represent one bit information. The watermark information is embedded in IVOP color quantized DCT DC coefficient. Not only video spectrum distribution is obtain without the additional change, but also the watermark is not impacted from DCT coefficients quantify. Experiments show that the watermark algorithm in MPEG-4 video achieved good results in the visibility and robustness through a variety of attack treatment.
