Abstract :
In this paper, we propose a bit-stream packetization approach to make the MPEG-4 still texture bit-stream robust to channel degradation. Our approach does not affect the spatial/quality scalability features of the still texture algorithm, and it has limited effect on coding efficiency. Also, this packetization approach requires minimal changes to the syntax and a small overhead. Finally, the proposed technique is shown to provide good error robustness over a wide range of error conditions
