中文摘要: 随着移动互联网技术与智能手持设备的发展, IPTV面临多屏融合的需求, 可伸缩编码技术可以很好地解决网速和设备分辨率的差异问题. 本文设计和实现了一套基于H264/SVC标准的高清实时IPTV系统, 通过对视频在时间、空间、质量上进行可伸缩编码, 以及TS解封装、AVC解码和TS流传输H264/SVC等模块的实现, 通过实时编码, 使拥有不同带宽和设备分辨率的用户能并发实时地观看节目. 实验证明了系统的有效性和稳定性.
Abstract:With the rapid development of mobile Internet technology and smart handheld devices in recent years, IPTV facing the demand of multi-screen integration. Scalable video coding technology can be a good solution to the differences in network speed and resolution of device. In this paper, we design and implement an HD real-time system of IPTV based on H264/SVC standard. The finalized H264/SVC standards are able to achieve scalable coding in the temporal, spatial, or fidelity domain. This paper presents a detailed introduction of TS encapsulation, AVC decoding and the encapsulation of SVC. By encoding the video in real-time, users with different bandwidth and device resolution concurrent viewing program in real-time. In the end of the paper, the experiments proved the effectiveness and stability of the system.
