摘要
根据无线信道的质量变化提出一种基于达芬奇技术平台上H.264视频编码库的动态参数优化配置方案,实现了无线信道自适应的实时动态视频质量的保障。详细介绍了无线视频传输系统的编码器端软件平台搭建过程,重点介绍了H.264编码库的参数意义及其优化配置。最后在达芬奇技术平台TMS320DM3730上得以实现,通过对WCDMA无线信道的测试验证该方案设计的有效性和可靠性。
In this paper,according to the quality change of wireless channel ,a dynamic parameter optimization scheme is proposed based on the H. 264 video encoding library of Davinci technology platform,and the adaptive real-time dynamic video quality of wireless channel is realized. After a detailed introduction of the software platform building process of encoder end in wireless video transmission system, the significance and optimal configuration of the parameters in H. 264 encoding library are focused on. Finally, this scheme is realized in the TMS320DM3730 ,which is one kind of Davinci platform. This scheme＇ s effectiveness and reliability is verified through the WCDMA wireless channel test.
