Embodiment Construction

[0032] The basic idea of ​​the present invention is: a conference control server is set in the wireless video conference system, and during the progress of the wireless video conference, the speaking party AT sends the signaling stream and / or data stream of the wireless video conference to the conference control server via the PCN, The conference control server acquires and controls to distribute the data stream to the non-speaking party AT.

[0033] Here, the data streams include information such as multimedia streams and local data; the multimedia streams are audio streams and / or video streams; one or more audio streams; one or more video streams.

[0034] During the wireless video conference, when the speaking party AT initiates a speech request, it will carry its own audio and video transmission link request in the speech request, and can request to transmit one or more audio streams or video streams, that is, the audio stream can be There are one or more channels, and the...

Abstract

The invention discloses a method for realizing wireless video conference and a method. A conference control server is set in a wireless video conference system; during the wireless video conference, an AT of a calling party sends siganlling stream and / or data stream of a wireless video conference to the conference control server through a PCN; and the conference control server obtains the data stream and controls as well as distributes the data stream to an AT of a non-call party. The invention can realize a multi-party wireless video conference and guarantee integrating control of wireless video conference function.

Description

technical field [0001] The invention relates to video conferencing technology, in particular to a system and method for realizing wireless video conferencing. Background technique [0002] Today, with the rapid development of computer and wireless network technology, traditional wireless communication methods such as telephone and fax cannot meet the increasing communication needs of people because of the inability to achieve face-to-face communication, and the growing wireless network environment makes video and audio Wireless transmission becomes possible, and a prominent application is remote wireless video conferencing. [0003] As the wireless broadband network is widely used in commercial use, the high-speed data transmission link of the wireless broadband network provides a guarantee for the transmission of large-flow information, and the wireless video function is widely used by people. Wireless broadband network structure such as figure 1 As shown, the wireless ac...
