Implementation of a Wireless Video Transmission System

In this paper, we propose a Bluetooth wireless transmission method based on compression standard H.261. We introduce a transmission system based on a H.261 codec, as a platform, on which the video data flow is transmitted using Bluetooth technique. A high-speed UART, which is simple and easy to implement on FPGA, is employed between the H.261 codec and the Bluetooth block, fulfilling the idea of controlling the data flow through software method, by which this system well implements the scalability of the algorithm for video coding and transmission mode. The experimental results show that the system works stably and has a good result.
