Embodiment Construction

[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0027] Embodiments of the present invention provide a multi-screen splicing display method and system.

[0028] refer to figure 1 The unit videos 1, 2, 3, and 4 divided by the same video are played synchronously on the four splicing unit screens a, b, c, and d, and the four splicing unit screens a, b, c, and d are realized. Play a complete video on the big screen;

[0029] can be used as figure 2 The method of video segmentation processing and multi-screen splicing display firstly undergoes video transcoding and video segmentation processing on the server, and then the client synchronizes the playback progress and splicing and displaying the complete video.

[0030] The detailed steps are,

[0031] 1. The serve...

Abstract

The invention relates to a multi-screen splicing display method and system, a server completes video transcoding and image segmentation in advance, and client hardware does not need to carry out image transcoding and segmentation processing. A plurality of clients directly receive the video signals of the server side without feeding back any information such as the positions of the clients to the server side, and only one-way receiving is needed. The interaction logic of the server and the client is omitted, and the development cost is reduced.

Description

technical field [0001] The invention relates to the technical field of video display, in particular to a multi-screen splicing display method and system. Background technique [0002] With the rapid development of digital image technology, multi-screen splicing image display has been more and more widely used in shopping malls, cinemas, stadiums and other large places. It not only solves the technical problems of high cost and difficult maintenance of a single large screen , and has extremely high scalability, and can be applied to the display of images of various sizes. For example, a video wall spliced ​​by LED or multiple TV screens, and a system for realizing scrolling display of subtitles on devices such as IPTV set-top boxes. [0003] However, the above solutions are all developed based on modules on the hardware system, that is, corresponding protocol instructions need to be written. The specific working principle is: the server communicates with the client, and the ...
