Abstract

Video encoding for multimedia services over communication networks has significantly advanced in recent years with the development of the highly efficient and flexible H.264/AVC video coding standard and its SVC extension. The emerging H.265/HEVC video coding standard as well as 3D video coding further advance video coding for multimedia communications. This paper first gives an overview of these new video coding standards and then examines their implications for multimedia communications by studying the traffic characteristics of long videos encoded with the new coding standards. We review video coding advances from MPEG-2 and MPEG-4 Part 2 to H.264/AVC and its SVC and MVC extensions as well as H.265/HEVC. For single-layer (nonscalable) video, we compare H.265/HEVC and H.264/AVC in terms of video traffic and statistical multiplexing characteristics. Our study is the first to examine the H.265/HEVC traffic variability for long videos. We also illustrate the video traffic characteristics and statistical multiplexing of scalable video encoded with the SVC extension of H.264/AVC as well as 3D video encoded with the MVC extension of H.264/AVC.

摘要

近年来，随着高效灵活的H.264/AVC视频编码标准及其SVC扩展的发展，用于通信网络上多媒体服务的视频编码取得了显著进步。新兴的H.265/HEVC视频编码标准以及3D视频编码进一步推动了多媒体通信的视频编码发展。本文首先概述这些新的视频编码标准，然后通过研究采用新编码标准编码的长视频的流量特性，探讨它们对多媒体通信的影响。我们回顾了从MPEG-2和MPEG-4第2部分到H.264/AVC及其SVC和MVC扩展以及H.265/HEVC的视频编码进展。对于单层（不可伸缩）视频，我们在视频流量和统计复用特性方面比较了H.265/HEVC和H.264/AVC。我们的研究首次考察了长视频的H.265/HEVC流量可变性。我们还阐述了采用H.264/AVC的SVC扩展编码的可伸缩视频以及采用H.264/AVC的MVC扩展编码的3D视频的视频流量特性和统计复用情况。
