Multimedia file demonstration method in video conference system

Abstract

The invention provides a multimedia file demonstration method in a video conference system. The multimedia file demonstration method comprises the following steps: configuration data of a server side is obtained; client sides are initialized; the client sides comprise a presenter client side, a keynote speaker client side and other participant client sides; the presenter client side authorizes a certain participant client side as the keynote speaker client side; the keynote speaker client side uploads one or more multimedia files to the server side; a server side address of a multimedia file currently opened by the keynote speaker client side is obtained, and synchronously downloaded by other client sides; furthermore, a corresponding multimedia file is opened; and multimedia file operation data of the keynote speaker client side is obtained, and transmitted to other client sides to demonstrate in real time. By means of the multimedia file demonstration method in the video conference system disclosed by the invention, the multimedia files and operation data thereof can be transmitted respectively and independently; the multimedia files are independently loaded according to a file address of the server side; an operation instruction is separated from audio and video flow data in a script form; the downloading bandwidth requirement is relatively low; and furthermore, the multimedia file demonstration fluency is effectively improved.

Description

technical field [0001] The invention relates to the field of video conferencing systems, and in particular to a multimedia file presentation method in the video conferencing system. Background technique [0002] Video conferencing system (Video conferencing System) is a communication system that uses communication network to transmit continuous moving images, sounds and data of multiple participants. Compared with teleconferencing, it has the advantages of strong intuition and large amount of information. The terminals of each venue are interconnected through the communication network to receive images, sounds and data from other venues; video conferences can not only hear the sound, but also see the participants, so that each participant has an immersive feeling; It is also possible to communicate through text chat; the conference system provides participants with rich data services through data control protocols, such as: file transfer, electronic whiteboard, desktop shar...

AI Technical Summary

Problems solved by technology

[0006] 1. The file is too large: audio and video is a form of presentation with high data volume and calculation requirements, which requires a lot of storage overhead

No matter on the local or server, the more multimedia files are presented, the longer the demonstration time will be, and there will be correspondingly greater overhead for local storage or network traffic, and this situation will be more obvious for mobile devices

[0007] 2. Poor screen adaptability. For example, a virtual video live broadcast collected according to the 1080p standard will have a good effect when played on a PC or TV, but on a 4:3 display device or a small screen such as a tablet or mobile phone When playing on the device, the effect is not satisfactory

[0008] 3. Copyright protection risk, no matter what kind of audio and video files, as an independent file form data, compared with other private data, it is easier to spread and infringe

In the remote video conference situation, the host or the speaker has different considerations about whether the conference process is open or disseminated, and the confidentiality of audio and video files cannot cover these different needs
