摘要

我们研究了对多个嵌入比特流进行分组的问题，以提高源代码的容错性。我们讨论了在低比特率和高比特率下针对数据包擦除的各种分组方案。我们将多个嵌入比特流的不同版本的最小失真分组作为离散优化问题，并提出了有效的算法来计算这些问题的全局最优解。

On optimal packetization of embedded bitstreams

We investigate the problem of packetizing multiple embedded bitstreams to improve the error resilience of source codes. We discuss various packetization schemes against packet erasure at both low and high bit rates. We formulate various versions of packetization of multiple embedded bitstreams for minimum distortion as discrete optimization problems, and propose efficient algorithms to compute globally optimal solutions to these problems.
