系统整体设计嵌入式高清视频无线传输系统的框图如图1所示。它主要由视频编码子系统、主控子系统、CDMA通信子系统3大部分构成。视频编码子系统中,采用TI公司的超低功耗图像解码芯片TVP5150,将模拟视频信号转换成数字视频信号输入到AT2061的视频输入接口,继而由AT2061实现高清视频编码产生两路不同分辨率的压缩视频流,此外,需要为AT2061配备专用的SDRAM存储代码及视频数据。主控子系统以STM3210FK为核心,利用32位总线外扩FLASH,SDRAM-The overall system design of embedded HD video wireless transmission system block diagram shown in Figure 1. It mainly consists of the video encoding subsystem, master subsystem constitute the majority of the CDMA communication subsystem. Video coding subsystem, using TI' s ultra low-power image decoding chip the TVP5150 analog video signals into the video input digital video signal input to the AT2061, high-definition video encoder generates two different resolutions and then by AT2061 compressed video stream, in addition, the AT2061 is equipped with dedicated SDRAM memory, code and video data. Master subsystem STM3210FK core, use the 32 bus outside the expansion of the FLASH, SDRAM,
