Abstract :
We study and implement a practical Internet videophone system, Cool-Video. Audio and video synchronization mechanisms based on dynamic windows, and a rate control mechanism based on F-VBR have been implemented in the system. Altering the data packeting method decreases the influence of packet-loss. All these have improved the performance of the system and provided better QoS to users
