A method and system for realizing multi-screen synchronous display

Abstract

The invention provides a method for synchronously displaying multiple screens, comprising: A. the source screen plays a video file, and acquires screen image data and sends it to the target screen for synchronous playback; B. the source screen sends the address information of the played video file and the current playback progress information of the video file is sent to the target screen in real time; C, the target screen reads the video file data according to the address information, and plays from the position corresponding to the received current playback progress information . A multi-screen synchronous display system is also provided correspondingly. By downloading the video file according to the source of the video file while transmitting the screen image for playback, the secondary synchronization of multi-screen sharing can be realized, and the screen capture and the playback of the video file itself can be realized. Seamless docking, so as to realize video synchronization, clear and smooth playback from small screen devices to large screen devices.

Description

technical field [0001] The invention relates to the technical field of information transmission, in particular to a method and system for realizing multi-screen synchronous display. Background technique [0002] "Three networks integration", also known as "three networks in one", refers to the mutual penetration, compatibility and gradual integration of the telecommunication network, cable television network and computer communication network into a unified information communication network in the world, which can provide users with voice , data and broadcast TV services. [0003] With the rapid development of the mobile Internet, multi-screen integration has become the current development trend of terminals, which can support various terminals to access video content of a terminal anytime, anywhere, so that it can be realized between TVs, computers, mobile phones and tablet computers. Sharing of video content, for example, sharing photos, videos, games, and interactive con...

Problems solved by technology

But if this method is to share the small-screen device to the large-screen device, the resolution and definition of the transmitted screenshot information are very low, and it is hesitant to transmit all the picture information, the data volume is huge, and it also contains a lot of redundancy. The rest of the data needs to occupy a large bandwidth

It can be seen that the currently commonly used video data sharing methods cannot achieve both fast synchronous playback and high-quality synchronous playback.
