Abstract
The invention provides a method and system for switching a conference terminal in a remote presentation conference, and a conference terminal. According to the embodiments of the invention, the conference terminal selects a work mode which comprises a combination mode and a decomposition mode so that the conference terminal can carry out media stream transmission with a multimedia input/output terminal in at least one meeting place according to the selected work mode. Since the conference terminal, apart from serving as a standard conference terminal to carry out the media stream transmission with the multimedia input/output device of one meeting place, can also be virtualized to form multiple standard common conference terminals to simultaneously carry out the media stream transmission with multimedia input/output devices in multiple meeting places, the problem in the prior art can be avoided that although a conference terminal is already disposed yet a remote presentation conference is not carried out, so resource waste of a remote presentation system is caused.
