This paper provides an overview of Video IP Phone\'s history and development, points out that these products possess the hardware design complexity,lower resolution images,more network bandwidth and higher price,etc,analyzes the significance of design and implement of a higher performance and cheaper Video IP Phone Teminal,puts forward the design scheme based on Freescale\'s i.

We use IP videophones talk to each other by means of audio and video data stream transmitting through networks, but the volume of the data are vast, the bandwidths are limited,it is completely out of the question to transmit these kind of data in uncompressed form.

The terminal has the IP videophone function and standard PSTN telephone function at the same time.

This paper brings up a design of the desktop video IP telephone system.
