用于实时的视频应用的飞行中擦除编码
On-the-fly erasure coding for real-time video applications
摘要：
本文介绍了一个强大的点对点传输方案：Tehrs，它依赖于一个新的飞行纠删编码的概念，减少了延迟恢复丢失的数据在接收端。在当前的纠删编码方案中，未在接收器侧重建的分组在传输到应用之前丢失或延迟至少一个RTT。目前的贡献，旨在证明，TECHNOLOGY编码方案可以填补实时的【形】应用程序的要求和完全可靠性之间的差距。事实上，我们表明，在几种情况下，Tequet可以恢复丢失的数据包低于一个RTT的损失和尽力而为的网络。我们还表明，Tehrs允许启用完全的可靠性，而不会延迟妥协，因此：显着提高了时间受限的应用程序的性能。例如，我们的评估提出，视频会议应用程序获得的PSNR增益高达7dB相比，经典的基于块的纠删码。
英文摘要：
This paper introduces a robust point-to-point transmission scheme: Tetrys, that relies on a novel on-the-fly erasure coding concept which reduces the delay for recovering lost data at the receiver side. In current erasure coding schemes, the packets that are not rebuilt at the receiver side are either lost or delayed by at least one RTT before transmission to the application. The present contribution aims at demonstrating that Tetrys coding scheme can fill the gap between real-time applications requirements and full reliability. Indeed, we show that in several cases, Tetrys can recover lost packets below one RTT over lossy and best-effort networks. We also show that Tetrys allows to enable full reliability without delay compromise and as a result: significantly improves the performance of time constrained applications. For instance, our evaluations present that video-conferencing applications obtain a PSNR gain up to 7dB compared to classic block-based erasure codes.
