随着我国高清电视的迅猛发展,4K高清视频的应用需要用到无线传输,视频的无线传输显得尤为重要。但现有的无线传输方案大都采用纯软件进行调制,而纯软件速度慢、代码多、调试难度高,对于高清视频的传输显得复杂。针对该问题,设计基于ZYNQ的无线视频流发送,通过ZYNQ的PS端进行数据发送控制,由集成调制芯片IT9517进行视频TS流的无线发送。该方案在保证处理速度和数据带宽的同时,还具有低功耗特点。测试结果表明,视频流能成功发送,具有一定的实用性。

With the rapid development of HDTV in China, 4K HD video applications require wireless transmission, and wireless transmission of video is particularly important. However, most of the existing wireless transmission schemes use pure software for modulation, while pure software is slow, has many codes, and has high debugging difficulty, which is complicated for the transmission of high-definition video. Aiming at this problem, a wireless video stream transmission based on ZYNQ is designed. The data transmission control is performed through the PS end of ZYNQ, and the wireless transmission of the...
