Abstract

A method of real-time video-audio interaction in an Internet game. An Internet transmission channel is established between Internet game clients without connection to the Internet game server. First, the method retrieves real-time video and audio data and compresses it into video and audio data packets. Next, the video and audio data packets are packaged into a transmission package to transmit to other game clients through the Internet transmission channel. Finally, the Internet game client receives the transmission package decompresses the received transmission package into video and audio data, and executes output thereof.
