State transition control method, multipoint control server and videoconferencing system

Abstract

Embodiments of the present invention provide a state transition control method, a multipoint control server, and a videoconferencing system. The state transition control method includes: receiving, by a multipoint control server, a conference reservation message, where the conference reservation message carries start time and end time of a reserved conference and an identity of a site centralized control device at a site participating in the reserved conference; and sending a state transition command to the site centralized control device according to the start time of the reserved conference and the identity of the site centralized control device at the site participating in the reserved conference or according to the end time of the reserved conference and the identity of the site centralized control device at the site participating in the reserved conference. In the embodiments of the present invention, through centralized control, in a non-conference state, external devices in a videoconferencing system enter a power-off state, and in a conference state, devices in the videoconferencing system are recovered to a normal working state, thereby improving user experience and reducing power consumption of the videoconferencing system.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technology, and in particular to a state transition control method, a multipoint control server and a video conference system. Background technique [0002] Video conferencing is a communication method that uses video output and input devices and audio output and input devices to hold meetings between users at two or more locations and transmit images and sounds in real time. At the same time, video conferencing can also transmit signals such as still images, files, and faxes. Those who participate in the video conference can express their opinions through the video output and input devices and audio output and input devices, and at the same time observe the image, movement and expression of the other party, and can show real objects, drawings and documents, etc., or display them on the blackboard, The words written and pictures drawn on the whiteboard make the participants ...

Problems solved by technology

[0003] However, all the components in the existing video conferencing system need to be manually powered on and off by the user, which is cumbersome to operate and has a poor user experience; moreover, users often forget to turn off the power after the meeting, wasting energy, and powering on all the time will also reduce Service life of components in videoconferencing systems
