Abstract

The invention discloses a double-screen or multi-screen tiled display method and system. Specifically, the method is characterized in that subtitles are entered through an input interface of a client, the client transmits the subtitles to a server, the server encodes the subtitles and transmits the encoded subtitles to two or multiple browsers, and the browsers connect to the server, receive subtitle streams and analyze and display them as scroll subtitles. The left browser and the right browser receive the subtitle streams at the same time; the left browser delay-displays the analyzed subtitles. The double-screen or multi-screen tiled display method and system according to the technical scheme has the advantages that interaction logic of the server and the client is omitted, the client computability is good, and development cost is low.

Description

technical field [0001] The invention relates to the field of video technology, in particular to the field of video composite display. 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 client sends parame...
