摘　　要：给出了一种无线视频传输系统的设计方法。发送部分的设计是基于TI开放式多媒体应用平台(OMAP),接收部分由普通PC控制。将采集到的图像数据按MPEG-4或MJPEG标准进行编码,得到的码流通过蓝牙进行传输。对于MPEG-4码流,帧率可以达到30 f/s,传输距离可以达到100 m。对于MJPEG码流,可以得到高质量的图片。当接收部分只接收数据而不进行解码时,80 m内的稳定的传输速率可达到1.1 Mb/s。This paper presents the design of a wireless video transmission system. The transmitting part is designed on the basis of TI＇s Open Multimedia Application Platform（OMAP）. The receiving part is controlled by common PC. The video data we collected is encoded by the MPEG- 4 or MJPEG standard,and the encoded bitstream is transferred by Bluetooth. For the MPEG- 4 bitstream,the frame rate can reach 30 f/s and the transmission distance can reach 100 meters. For the MJPEG bitstream, the picture with high quality is received. When the receiving part receives data only and doesn＇t decode the data, the stable transmission speed can reach 1.1Mb/s in 80 meters.
