Description

Realize the method for videoconference
Technical field
The present invention relates to the video conferencing technology of field of multimedia communication, refer to a kind of method that realizes videoconference especially.
Background technology
Along with the fast development and the expansion of telecommunication market, landline telephone, mobile phone have all obtained popularizing and application more and more widely.That increasing people need is fast, easily with various information and important affairs and all affected members' concentrated discussion, reception and registration and issue etc.In order to keep up with the trend of the times, adapt to the flourish of each large and medium-sized enterprise, satisfy users' demand, improve the operating efficiency and the economic benefit of each big enterprises and institutions, videoconference, video conference begin to enter each big enterprises and institutions as an emerging product.
The function that videoconference, video conference provide brings great convenience to users, needn't be again hurrying back and forth among frequent meeting is gone on business from afar, thereby saved manpower, financial resources and material resources widely, and the more important thing is and saved a large amount of time.Videoconference can incorporate in the video conference by field type with phone.General realize that videoconference comprises three aspects: videoconference is held, videoconference control and meeting safety.
For the mode that videoconference is held, the mode that present videoconference is held has two kinds, and a kind of is WEB reservation, and another kind is by the direct port operation meeting on turnkey console of keeper.
The roughly process of WEB reservation is as follows:
1) the conference convening person adopts legal users name and password to sign in to WEB website, conference telephone center earlier;
2) the conference convening person defines relevant participant's data, telephone number, affiliation password, meeting beginning and ending time etc.;
3) port operation meeting;
Dial in number, meeting start time and affiliation password etc. when 4) caller notifies the participant to participate in a conference.
The mode that the conference telephone system keeper directly dispatches:
1) the conference convening person passes to the conference system keeper to related data;
2) the conference system keeper defines relevant participant's data, telephone number on turnkey console, affiliation password, meeting beginning and ending time etc.;
3) port operation meeting.
Dial in number, meeting start time and affiliation password etc. when 4) the conference system keeper notifies the participant to participate in a conference.
