abstract
This paper addresses the problem of optimal packetization for Fine Granularity Scalability (FGS) bit stream. A very general performance metric for streaming FGS bit streams over packet erasure networks is first defined and analyzed. Then three packetization strategies, namely the baseline packetization, the binary-tree packetization and the optimal packetization are presented, justified and compared. Finally, some experimental results are presented to demonstrate the effectiveness of the packetization schemes.
