本文提出一种新的用于提高MPEG系统编码效率的速率控制方案。
This paper proposes a new rate control scheme to increase the coding efficiency for MPEG systems.
该方案采用了主动标记分层、适应性效用分层策略、逐跳反馈归并以及主动速率控制算法。
Active label layering, adaptive utility layering policy, hop-by-hop feedback merging and active rate control algorithms are adopted in DL-AALM scheme.
与其他方案不同，该机制进一步考查了无线包错误率对包长调整和速率控制的影响。
Unlike other proposals, this mechanism takes the impact of wireless packet error ratio (per) on the packet size adjustment and performance of rate control into consideration.
