摘　　要：基于ZigBee的H.263标准视频采集传输研究实现H.263标准的无线视频采集传输功能。由无线收发模块(CC2430)、USB接口(CH375)、免驱USB摄像头和电源等构成基于ZigBee的H.263标准视频采集传输硬件。CH375芯片以主机方式请求免驱USB摄像头进行视频采集,获取视频数据的组织及视频格式,以异步UART模式传送给CC2430芯片,由CC2430芯片自带的8051微处理器将视频格式转换成H.263标准,通过ZigBee网络无线传输。经过在室内测试距离为20 m的无障碍环境中对H.263标准的QCIF和CIF图像格式以不同的帧速进行比特率、MSE和PSNR等3个参数的画面测试,结果表明视频传输有效、稳定。Research of H.263 video capture and transmission based on ZigBee realized H.263 video capture and transmission.The hardware of H.263 video capture and transmission based on ZigBee consisted of CC2430,CH375,drive-free USB camera and power,etc.CH375 requested the drive-free USB camera for video capture as USB-HOST model,and acquires the video data organization and video format,then sents to CC2430 at asynchronous UART model,MCU 8051 in CC2430 converted the video formats to H.263 standard.These video signals were transferred at ZigBee wireless network.After making image test about bit-rate,MSE and PSNR parameters,in the indoor 20-meter distance and barrier-free environment on QCIF image format and CIF image format of H.263 standard with different frame rate,the results show that the video transmission is effective and stable.
