Problems solved by technology

[0003] In practical applications, there are many pictures that need to be synchronized. If the speaker end sends each picture to the central controller or directly to other clients, the amount of transmitted data will be huge, which will cause instant network congestion and slow picture download speed. The image synchronization time is long and the efficiency is low, which is not conducive to the real-time application of teaching and other applications

Abstract

The invention discloses a multimedia synchronizing method, device and system which are used for improving the synchronizing efficiency between teachers and students. The method comprises the steps of obtaining multimedia on a local interface, sending the multimedia to a central controller when the multimedia does not come from the central controller, obtaining a multimedia ID corresponding to the multimedia and sending the multimedia ID to a second client, wherein the multimedia ID is used for instructing the second client to obtain the multimedia corresponding to the multimedia ID from the central controller and enabling the multimedia to be displayed and the central controller is used for storing the multimedia and the multimedia ID corresponding to the multimedia.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a multimedia synchronization method, device and system. Background technique [0002] In a multimedia conference, the speaker not only needs to display word, pdf, ppt and other files during the narration process, but also write notes during the narration process. In related technologies, the content displayed on the screen of the speaker terminal is usually uploaded to the central controller in the form of pictures, and the central controller sends the pictures to other terminals, or directly sends the pictures to other terminals. [0003] In practical applications, there are many pictures that need to be synchronized. If the speaker end sends each picture to the central controller or directly to other clients, the amount of transmitted data will be huge, which will cause instant network congestion, and the picture download speed will be too slow. The image synchronization ...
