摘要
在分析视频压缩H.264/AVC标准的基础上,采用DSPTMS320C6416和ARM微控制器,设计并实现了一个灵活、高性能的支持网络化传输的视频压缩平台。详细描述了系统结构原理、各部分硬件设计和编码算法过程。该平台把DSP的强大运算功能与嵌入式微处理器的网络传输和远程控制功能相结合,能满足压缩算法多种多样而且复杂的要求,支持RTP/UDP/IP网络协议互联。在工业以太网环境下应用表明,系统具有优秀的PSNR性能。
Firstly, on the basis of analysis for video compression standard H. 264/AVC, DSP TMS320C6416 and ARM microcontroller are used to implement a flexible compressed platform with high quantity embedded digital video. Then the principle of system structure, hardware design and encoding algorithm in are illustrated details. This platform combines computation ability of DSP with networking transfer and remote control ability of embedded MCU, which satisfies the demand of complicated and various compressed algorithm, and supports the interconnection of RTP/UDP/IP protocols. Application in scenario of industrial ethernet shows that its PSNR is very excellent.
