Technical Field
The invention relates to the field of multimedia conferences, in particular to a multimedia conference control method and a multimedia conference control system.
Background
Multimedia conferencing systems generally refer to the integration of audio, optical, electrical devices and software that are interrelated with a conference. In the multimedia conference room, no matter whether reporting, summarizing, reporting, introducing products and the like are carried out, the picture, the text, the sound, the shadow and the picture are displayed by the interactive operation of the computer, the sensory perception of the participants is fully aroused, and the conference effect is greatly improved. Multimedia is also becoming more and more advantageous in the office field. The multimedia conference is held mainly by the following modes: 1. the conference is realized by inviting conference members to join the conference in real time on line under the multimedia condition. Such conferences are generally suitable for instant discussion conferences where conference members may speak at will. The conference chairman can not control the conference flow in real time through software, the conference end members are dismissed, and the conference is re-invited when the conference is started next time, so that the time waste and the rhythm of the conference are caused, and the complicated and changeable conference form can not be met. 2. And a conference template, wherein the conference is realized by grouping conference members into a group before the conference and informing the conference members needing to participate in advance. The members are ready online before the conference begins, and the chairman initiates the conference through the conference template. The conference mode can reduce the time for inviting the members before the conference begins, can simply carry out operation control on the conference members, and can repeatedly use the conference template. However, when a large conference or multiple conference resources are merged, the conference template cannot execute related actions according to a preset conference flow, cannot accurately master conference time, is easy to miss conference items, and lacks a real conference scene.
