Method, device and system for file sharing in audio/video conference

Abstract

The embodiment of the invention discloses a method for realizing document sharing in audio and video meetings, which comprises that the information which is transmitted by a document sharing sponsor is received in the audio and video meetings, the information requests to create a document sharing data meeting; a data meeting is built by the sponsor which is added to the data meeting; the SDP information distributed to an interception port of the data meeting is carried to the response information which is transmitted to the sponsor, so that the sponsor uploads the data document conveniently according to the SDP information of the interception port. The invention also discloses a device and a system for realizing document sharing in audio and video meetings. When the audio and video meeting is held, the device and the system can share the date document to other members in the meeting simultaneously, and has less alternations to the system and has low realizing cost.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and system for realizing file sharing in an audio and video conference. Background technique [0002] A commonly used method for realizing file sharing in an audio and video conference is to combine an audio and video conference based on the H.323 protocol with a data conference based on the T.120 protocol specified by the International Telecommunication Union (ITU: International Telecommunication Union), to Realize the sharing of data files in audio and video multimedia conferences. This method generally has two modes of in-band communication and out-of-band communication. [0003] figure 1 It is a schematic diagram of the system structure using in-band communication. In-band communication requires audio, video and data to share a bandwidth. When a terminal joins a conference, the bandwidth is specified by the H.323 media server (MS). In a conference, ...

AI Technical Summary

Problems solved by technology

It can be seen that both servers need to organize different conferences, that is, audio and video conferences and data conferences, and also organize complex logic to associate the two conferences. However, since the H.323 media server and the T.120 server handle Signaling of different protocols, therefore, there will be fusion problems between the two servers

Moreover, because audio and video and data share the same broadband in the prior art and use the same port to transmit information, once the H.323 is dropped, the data server will also be interrupted. Moreover, if the data server does not have broadband control, then if suddenly Sending data will result in loss of audio and video
