Abstract : The alteration of compressed video bitstream due to embedding of digital watermark tends to produce unpredictable video bit rate variations which may in turn lead to video playback buffer overflow/underflow or transmission bandwidth violation problems. This paper presents a novel bit rate control technique for compressed video watermarking applications. The proposed method offers much more flexibility and scalability than the pioneering schemes from Hartung and Girod. Experimental results show that the proposed bit rate control scheme is effective in meeting the bit rate targets, and is capable of maintaining good watermark detection robustness and perceptual quality for the watermarked bitstream.
