Low-complexity priority based packet scheduling for streaming MPEG-4 SLS

Abstract

In this paper, we propose a low-complexity priority based packet scheduling algorithm for streaming MPEG-4 Scalable to Lossless (SLS) encoded audio. In the proposed system, the SLS encoded frames are partitioned into data units of different quality layers, which are transmitted according to their quality contribution to the final decoded audio and their urgency relative to the playback progress. Experimental results show that the proposed scheduling algorithm has an even lower compared to traditional greedy algorithm for packet scheduling, while outperforms them by a significant margin in for terms of quality of the streamed audio.
