摘　　要：由于无线信道具有易错、时变和带限的特点,视频业务数据量大,对误比特率要求高,针对这些特点设计一种基于ADSP-BF537的无线视频系统。设计中运用DSP+FPGA的方案,以ADSP-BF537为例,利用DSP动态配置FPGA并与视频服务器、FPGA进行数据通信。测试证明,该系统在不同信噪比下误码率低,克服了无线信道传输易误码的缺点,满足了视频传输对误码率的高要求。A total block diagram of wireless video transmission system and the hardware platform and implementation of the overall structure are proposed. Emphasis on the introduction of DSP＋FPGA used in the design. Taking the ADSP- BF537 as an example,it elaborates DSP dynamic to dispose FPGA from the software and hardware designs as well as the process of data communication among the DSP, the video server and the FPGA. Testing result indicates that this system is reasonably designed and runs reliably.
