Abstract

The invention discloses a method and system for achieving double-screen or multi-screen tiled display. The method includes the specific steps that subtitles are input through an input interface of a client, and the client sends the subtitles to a server; the server carries out encoding processing on subtitle information, and the subtitle information is sent to browsers; the browsers are connectedwith the server to receive a subtitle information stream, and the rolling subtitles are displayed after analysis, wherein the number of the browsers is two or more, the left browser and the right browser simultaneously receive the subtitle stream, and the left browser displays the analyzed subtitles in a delayed mode. According to the technical scheme, interaction logic between the server and theclient is omitted, the compatibility of the client is good, and the 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 paramet...
