This system combines modem digital communication and frequency modulation analog signals transmission by acoustic coupling;and is applicable to the telemedicine and the long-term health monitoring in families, and also offers heart disease service network.

The video transmission technique on closed-circuit TV monitoring and control system for coal mines;

Multiple site,real-time video transmissions for remote control systems;

The software design of video transmission in wireless video surveillance system;

Design and implementation of video transferring system based on IP multicast;

In order to enforce the transferring speed,the Huffman algorithm is adopted to deal with the compression and decompression of the image,presenting the way of speeding the video transferring ,which makes the video refresh more quickly.
