摘要

第二代卫星数字视频广播(DVB-S2)标准允许使用通用流封装(GSE)协议直接传输IP内容，取代现有的传输流(MPEG-2 TS)。这代表了当前两种封装方法的演变:对MPEG-2编码应用程序在TS上本机使用分组基本流(PES)，以及对基于ip的MPEG-4编码内容在TS上使用多协议封装(MPE)和单向轻量级封装(ULE)等自适应协议。本文回顾了这一演变，并分析了这种纯ip架构所带来的开销改进。本评估考虑了使用稳健报头压缩(ROHC)对DVB-S2 IP/ gse纯传输效率的影响。

Impact of ROHC on IP encapsulation efficiency in a DVB-S2 GSE-only transmission system

The 2nd generation of Digital Video Broadcasting for Satellite (DVB-S2) standards allows the direct transmission of IP content using the Generic Stream Encapsulation (GSE) protocol, replacing the existing Transport Stream (MPEG-2 TS). This represents an evolution from the two current encapsulation methods: the native use of the Packetized Elementary Stream (PES) over TS for MPEG-2 encoded applications and, the use of adaptation protocols such as the Multi-Protocol Encapsulation (MPE) and the Unidirectional Lightweight Encapsulation (ULE) over TS for IP-based MPEG-4 encoded content. This paper reviews this evolution and analyses the overhead improvement resulting from this IP-only architecture. This evaluation considers the impact of using RObust Header Compression (ROHC) on the efficiency for DVB-S2 IP/GSE-only transmission.
