Method and system for achieving synchronous display of multiple screens

Abstract

The invention provides a method and system for achieving synchronous display of multiple screens. The method comprises the steps as follows: A, a source screen plays a video file, obtains screen image data and sends the screen image data to a target screen for synchronous play; B, the source screen sends address information of the played video file and current playing progress information of the video file to the target screen in real time; and C, the target screen reads data of the video file according to the address information and plays the data in a corresponding position of the current playing progress information. The invention further provides a system for synchronous display on the multiple screens. The video file is downloaded according to the source of the video file while a transmission screen image is played, so that sharing and secondary synchronization of the multiple screens can be achieved, seamless joint of playing screen shot and the playing video file is achieved, and accordingly, video synchronous, clear and smooth playing from a small screen device to a large screen device is achieved.

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-network integration" is also called "three-network integration", which refers to the mutual penetration and compatibility of telecommunication network, cable TV network and computer communication network, and gradually integrates into a unified information communication network all over 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 development trend of the current terminal, which can support various terminals to access the video content of a certain terminal anytime and anywhere, so that it can be realized between TVs, computers, mobile phones, and tablets. The sharing of video content, for example, sharing photos, videos, game...

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.
