摘要
采用现有的3G移动通信网络来实现无线视频传输的方法适合远距离使用,在近距离时使用这种传输方式不仅费用高,而且带宽得不到保证。针对以上问题设计了一种近距离无线视频传输系统。系统采用专用的JPEG2000视频压缩器件ADV212来实现视频压缩;基于多外部接口和低功耗的考虑,选用Cortex-M3内核的嵌入式处理器LPC1768对整个系统进行控制;无线传输采用nRF24LU1+来实现。
Existing 3G mobile communication networks for wireless video transmission is the popular way for a wide range of people. But at close range, the use of this transmission needs high cost and the bandwidth is not guaranteed. To solve the above problems, a shortrange wireless video transmission system is designed. The design uses dedicated JPEG2000 video compression device ADV212 to achieve video compression. Based on external interfaces and low power consumption considerations, ARM Cortex-M3 core with an embedded processor LPC1768 to control the system is chosen. Wireless transmission adopts nRF24LU1＋.
