Abstract

The invention is applicable to the field of a multi-screen interaction technology and provides a screen synchronization method and a screen synchronization device. The screen synchronization method comprises the following steps of: respectively obtaining a resolution ratio of a first screen of a first terminal and a resolution ratio of a second screen of a second terminal; determining a zooming coefficient and a rotating parameter according to a relation between the resolution ratio of the first screen and the resolution ratio of the second screen; mapping a first coordinate of the first screen to a second coordinate of the second screen according to the determined zooming coefficient and the determined rotating parameter; and setting display data on the second coordinate to displaying data of the first coordinate to enable the second screen to display displaying content of the first screen. A mapping relation of the screen coordinates is subjected to self-adaptive adjustment according to the screen resolution ratios of the two terminals for carrying out synchronous display, so that the synchronous display of the different screens in multi-screen interaction is realized, a user does not need to manually set and the operation efficiency of the multi-screen interaction is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of multi-screen interaction, and in particular relates to a screen synchronization method and device. Background technique [0002] With the development of multi-screen interactive technology, multimedia content can be transmitted, analyzed, displayed and controlled on different multimedia terminals such as smartphones, tablets, TVs, and computers, and multimedia content can be shared on different terminal devices at the same time. For example, playing a video in a mobile phone on a TV, or viewing pictures in a mobile phone on a tablet computer, thereby bringing convenience to the user's multimedia life. [0003] The key to multi-screen interactive technology is to realize the synchronous display of screens between different terminal devices, and further realize the synchronous control of the screens on the basis of synchronous display of screens. However, the hardware manufacturers of different screens may...
