This paper is to propose a digital watermarking protect the ownership of video content which compressed by H.264/AVC main profile. scheme intends be performed during CABAC (Context-based Adaptive Binary Arithmetic Coding) process entropy coding It uses contexts extracted context modeling position watermark bits simply checking values and determining coefficients. The also as simple replacing bit with LSB (Least Significant Bit) corresponding coefficient watermarked. Experimental results from applying this attacking in various ways such blurring, sharpening, cropping, Gaussian noise addition, geometrical modification showed that embedded has very high imperceptibility robustness attacks. Thus, we expect it used good scheme, especially area should compression requiring minimal amount for watermarking.
