Abstract

The embodiment of the present invention discloses a subtitle data processing method, comprising: receiving a subtitle broadcast request, the subtitle broadcast request carrying subtitle information, node machine operating parameters and broadcast parameters; acquiring subtitles matching the subtitle information, and following Performing texture rendering on the font information in the operating parameters of the node machine to generate a subtitle unit with a preset format; cutting the subtitle unit according to the resolution of the operating parameters of the node machine and the font information to generate at least one subtitle unit; The broadcast parameter encapsulates the subtitle unit and the broadcast parameter of the task node machine and sends them to the corresponding node machine. The method separates subtitle broadcasting from subtitle rendering and production, and realizes the technical effect of realizing full font library broadcasting on a node machine with limited font library.

Description

technical field [0001] The present invention relates to the technical field of subtitle display, and more specifically, to a subtitle data processing method, device and system. Background technique [0002] Subtitle broadcasting is a modern subtitle processing technology applied in publicity, identification and display. Subtitle broadcasting needs carriers such as LED display screens to display subtitle content to viewers and process subtitle data with the help of subtitle clients. Take the distributed display platform as an example to illustrate: [0003] The distributed display platform is a system that uses multiple node machines as display output devices, and each node machine cooperates to output the specified number of words and fonts. Taking the distributed display platform embedded in the LINUX operating system as an example, the LINUX operating system installed on each node machine supports basic fonts such as Song, Hei, Kai, and imitation Song. [0004] When faced...
