Problems solved by technology

[0004] This method needs to connect the display to the host terminal by wire connection, which is not convenient and cannot be applied to smart terminals without wire connection. With the rapid development of terminal technology, people use smart terminals more and more frequently , there is no good solution to the problem of using multiple smart terminals to collaboratively display different areas of the same image

Embodiment approach

[0120] For the first specific implementation manner of step S310, the determination of the corner of the rectangle in the image recognition technology may be used to determine the new relative position information of the display terminal whose position has changed in the target area;

[0121] For the second specific implementation manner of step S320, after it is determined that the position of any display terminal has changed and which specific display terminal has changed, the control terminal may take an image of the target area, and compare the image with the initial image (initial The image is an image of the target area taken by the control terminal before the display terminal cooperates to display), and the new relative position information of the display terminal in the target area whose position has changed is determined by using the judgment of the corner of the rectangle in the image recognition technology.

[0122] S330: Send the determined new relative position inf...

Abstract

The embodiment of the present invention discloses a multimedia file multi-terminal cooperative display method, device and system. A multimedia file multi-terminal cooperative display method includes the following steps: obtaining the screen characteristics of each display terminal; determining the image used to display the target multimedia file The target area of ​​the target area; according to the screen characteristics of each display terminal, determine the relative position information of the screen area of ​​each display terminal in the target area; send the determined relative position information to the corresponding display terminal; The display terminals send a coordinated display instruction, so that each display terminal displays the corresponding area image of the target multimedia file according to the relative position information of its screen area in the target area. By applying the technical solutions provided by the embodiments of the present invention, when the display terminal is an intelligent terminal and there is no wire connection, coordinated display of multiple display terminals can be realized, which improves convenience.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a multi-terminal cooperative display method, device and system for multimedia files. Background technique [0002] In the current advertising, film and television, information release and other fields, there is often a need to display multimedia files in a large area. A single display terminal is limited by its screen size and often cannot meet this demand. This requires the use of multiple Each display terminal displays multimedia files, and each display terminal displays a different area of ​​an image. [0003] The existing multi-terminal cooperative display method is to connect multiple displays to the same host terminal by means of wire connection, and the host terminal controls the multiple displays to display different areas of the same image. [0004] This method needs to connect the display to the host terminal by wire connection, which is not convenient and ca...
