On packetization of JPEG2000 code-streams in wireless channels

摘要

The JPEG2000 standard adopts an error-resilient structure to organize its code-stream. Meanwhile, this robust structure also provides potential optimization space for packetization algorithms. In this paper, we study the optimal packetization issue for JPEG2000 code-streams over wireless channels. We first discuss the best strategy for packetization hits from an individual code-block into channel packets. Then, we extend it to bits from a group of code-blocks. Experimental results indicate that our scheme is outperforming the normal method by significant margins.
