摘要

有效利用带宽的需求和如何处理无线信道的带宽波动情况已经成为视频传输中的基本问题。本研究采用可扩展视频编码(Scalable Video Coding, SVC)，即联合可扩展视频模型(Joint Scalable Video Model, JSVM)，即利用多输入多输出-正交频分复用(MIMO-OFDM)无线信道上的可扩展组合方法开发H.264/AVC视频编码。研究表明，可扩展组合方法可以在组播网络视频传输场景下实现。实验结果表明，MIMO-OFDM系统的传输质量接近传统的同步传输机制。

Combined scalability technique for video transmission over wireless channel with MIMO-OFDM systems

The needs of efficient bandwidth utilization and how to handle fluctuation bandwidth condition of wireless channel have became fundamental problems in video transmission. This research uses Scalable Video Coding (SVC) that refers to Joint Scalable Video Model (JSVM), i.e. development of video coding H.264/AVC by exploiting scalable combination method on wireless channel of Multiple Input Multiple Output — Orthogonal Frequency Division Multiplexing (MIMO-OFDM). This research shows that the scalable combination method can implemented on the scenario of video transmission on multicast network. Experimental results are presented that the delivered quality is close to the alternative traditional simulcast delivery mechanism in MIMO-OFDM systems.
