摘要

介绍了一种用于MMT自适应应用层FEC (AL-FEC)的速率自适应FireFort-LDGM (FF-LDGM)代码。FF-LDGM代码是2015年2月发布的ISO/IEC MPEG国际标准。它可以处理从少量数据包到数千个数据包的各种块长度。特别是对实时超高清视频传输非常有用。本文重点介绍了频率自适应FF-LDGM码的最新研究进展。它提供了一个速率自适应功能，允许自适应地改变编码速率以适应网络特性。我们通过选择性交错提高了速率自适应方案的错误恢复性能。仿真结果表明，该方法具有良好的自适应性能。

Rate-adaptive FF-LDGM code with selective inter-leaving scheme

This paper introduces a rate-adaptive FireFort-LDGM (FF-LDGM) code for MMT adaptive Application Layer FEC (AL-FEC). The FF-LDGM code is an ISO/IEC MPEG international standard issued in Feb. 2015. It can handle a wade range of block lengths from a small number of packets to several thousands of packets. Especially, it is useful for real-time UHD video transmission. In this paper, we focus on recent advances in the rate adaptive FF-LDGM code. It provides a rate adaptive function that allows the coding rate to be adaptively changed to suit the network characteristic. We improve the error recovery performance of the rate-adaptive scheme by using selective interleaving. Simulation results demonstrate its superior adaptive performance.
