摘要

在本文中，我们研究了多描述编码(MDC)和多输入多输出(MIMO)技术在交通应用无线嵌入式实时视频监控中的联合使用。这两种技术的结合有望提供传输数据的可靠性和重构视频信号的优雅降级。本文提出的传输链基于WiMAX IEEE 802.16d标准。它由一个与OFDM物理层相关联的2times4 MIMO系统组成。相对于实际的H.264/AVC压缩标准，已经开发了不同的MDC算法。为了说明所提出的解决方案在错误鲁棒性和解码视频质量方面的兴趣，给出了初步的结果并进行了讨论。

Robust video monitoring system for transport applications based on joint use of multiple description coding and multiple antennas

In this paper, we investigate the joint use of multiple description coding (MDC) and multiple-input multiple-output (MIMO) technology in the specific context of wireless embedded real time video surveillance for transportation applications. The combination of both techniques is expected to provide reliability of transmitted data and graceful degradation of reconstructed video signal. The transmission chain proposed in this work is based on the WiMAX IEEE 802.16d standard. It consists in a 2times4 MIMO system associated with an OFDM physical layer. Different MDC algorithms have been developed with respect to the actual H.264/AVC compression standard. Preliminary results are presented and discussed in order to illustrate the interest of the proposed solution in terms of error robustness and decoded video quality.
