As the demand for live video communication increases, the devices available to the users need to be made faster, smaller, lower power, and easily modifiable. This project demonstrates an example video over IP application using a Compaq IPaq along with a field programmable gate array used for data processing. The video data is passed directly from the camera to the network card via the gate array, thus avoiding unnecessary delay and computation requirements imposed on the CPU by regular video over IP communication software. The application achieves a display rate of 9 frames per second with 76800 byte frames, corresponding to a wireless throughput of 5.5Mbps. The CPU usage is reduced to 1/3 of that used by a standard video over IP implementation operating at the same rate.
