Abstract

In this paper, a simple and efficient strategy of quality control for mobile multimedia transmission is proposed. Based on embedding the watermark into the transmitted media as the channel indication index and using the human visual/auditory sensitivity property, the dynamic bit allocation strategy is adopted accordingly thus to obtain the best quality of the media contents under a fixed bit rate constraint. The simulation results show that by using the proposed channel predication method and bit allocation strategy, not only more transmission efficiency can be achieved but the copyright protection requirement is still met, while only increasing little computational complexity at the mobile terminal.
