MPEG编码流中不同的结构成分在图像恢复时具有不同的重要性
针对此特征
本文将优惠券机制与媒体流的网络传输相结合
提出了基于优惠券机制的TCP友好不等保护传输方案(CTFUPS).仿真结果表明
该方案能够保护码流中对图像恢复质量起关键作用的结构描述字段
减少图像帧的丢失
有效改善图像传输质量.
As different coding structures of MPEG video influence the video reconstruction quality differently
this paper introduces a new scheme to deliver streaming applications over Internet
which is named as Coupon-based TCP Friendly Unequal Protection Scheme (CTFUPS).This new approach provides different level of protection denoted by coupon value to the different structures.The simulation results exemplify that our approach can decrease the frame-loss ratio and improve the video reconstruction quality efficiently.
