File synchronous playing method and system for video conference

Abstract

The invention discloses a file synchronous playing method and system for a video conference, and the method comprises the steps: collecting a file list of an auxiliary machine into a total file list through the auxiliary machine actively mounted by a host; after the first auxiliary machine initiates a play control request, searching a to-be-controlled file corresponding to the play control request in the file total list through the host, and sending the play control request to other auxiliary machines, so that the to-be-controlled file corresponding to the play control request is searched in the corresponding remote file list, a playing control instruction is sent to playing systems corresponding to other auxiliary machines, and after corresponding playing service processing is carried out, the playing state is sent to the host in an RPC remote calling mode; and after the host receives the playing state of each auxiliary machine, recording a corresponding final state, and controlling other auxiliary machines to synchronously play the file through the host. According to the invention, the synchronous playing of files between the host and the plurality of auxiliary machines through the network can be realized on the premise that the auxiliary machines do not need to be in the same network segment.

Description

technical field [0001] The invention relates to the technical field of video conferencing and wireless communication, in particular to a method and system for synchronously playing files used in video conferencing. Background technique [0002] In the existing large-scale video conferencing room, due to the large venue, in order to ensure that multiple participants can have a better conference experience, the video conferencing hardware system generally consists of a host and multiple touch panel accessories. Control panel accessories have their own storage media respectively, and also support USB port to expand external storage media. In the prior art, when many people in a large-scale video conference room have a meeting and need to share multimedia files such as video, audio or pictures prepared for presentation, the multimedia files can only be copied to the host computer through a U disk and projected on the large screen, and a A dedicated person plays the video. When ...

Problems solved by technology

[0003] However, in the process of research and practice of the prior art, the inventor of the present invention found that the prior art has the following defects in the way in which a dedicated person controls the host computer to play files: when the number of people participating in the video conference If there are too many, it will greatly affect the efficiency of the meeting; in addition, when the participants need to project the meeting documents to different computers, if the different computers are not in the same network segment, they cannot directly communicate with each other, resulting in the inability to complete the sharing of meeting documents , very poor user experience
