A scheme of wireless real video transmission with optimized Quality-of-service is proposed in this paper. It combines H.264 video compression technology with Bluetooth technology to reduce demand of bandwidth and power consumption. Resource manager (RM) is used to smooth video output traffic and to partially eliminate peak of video stream transmitted in Bluetooth channel. The RM monitors status of video transmitters, manipulates and coordinates the being encoded video, and adopts traffic credits to support real-time video services. Measured results show that a maximal speed of transmission can be achieved with a best suitable ACL packets type, rather than the maximum payload packet, according to SNR to achieve. The system can support real-time video transmission with good quality. And more, it can be realized easily in mobile application for its good transportability and robustness.
