Abstract

A system and method for transmitting video and audio information among communicating wireless devices during a video conference in a wireless communications system. The audio information from all participants is received by a server, which selects a speaker among the participants. The speaker's audio and video data are transmitted to all participants according to a predefined criteria.

Description

technical field [0001] The present invention relates generally to wireless telecommunications, and more particularly, to a system and method for optimizing video and audio data transmission during video / audio conferencing in a wireless network. Background technique [0002] Advances in technology have made mobile phones or wireless communication devices cheap and affordable to nearly everyone. As wireless telephones are manufactured with higher and higher processing power and storage capacity, they also become more functional and include many features, including the ability to support real-time video and audio conferencing. Wireless phones can be equipped with a resident camera and display images from that camera to other devices in the wireless network. During a video conference, users can see the images of the participants and hear the voices of the same participants at the same time. [0003] During a video conference, the audio and video data of a speaking party is tra...
