摘　　要：提出了一种基于H.2 6 1标准和蓝牙标准的视频压缩算法的无线传输系统。系统以自主研制开发的H.2 6 1标准的视频编、解码板为平台,通过蓝牙进行无线视频数据传输,在编解码板和蓝牙模块之间采用了简单方便而且技术相对成熟的高速UART,并采用FPGA来实现,能通过软件实现对数据码流的控制。因此,系统很好地实现了视频数据压缩算法和传输方式的可升级性。实际应用表明,该系统取得了良好视频效果,具有很好的应用前景。This paper proposes a new video transmission method fitting for video based on H.261 and Bluetooth compressing standard over wireless channel. A transmission system based on a H.261 codec as a platform, on which the video data flow is transmitted using Bluetooth technique. A highspeed UART which is simple and easy to implement on FPGA, is employed between the H.261 codec and the Bluetooth block, fulfilling the idea that to control the data flow through software method, By which this system implements the scalability of the algorithm for video coding and the transmission mode. The experimental results show that the system works steadily and has a good effect.
