Embodiment Construction

[0062] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0063] figure 1 It shows the system structure composition based on unattended distributed, multi-thread subtitle rendering and playout engine. Deploy cluster rendering workstations according to equipment conditions, and formulate rendering tasks for each workstation before rendering. The monitoring and error handling terminal is used to collect the rendering status of each rendering workstation, collect error information and process it.

[0064] ●Workflow

[0065] (1) in figure 1 In , each rendering machine receives different rendering tasks, and a task distribution workstation can be used to distribute rendering tasks, or it can be manually arranged on each rendering machine. The task distribution workstation is not described here, and the latter method is used uniformly.

[0066] (2) After the rendering machine receives the task, it can u...

Abstract

This invention refers to the caption broadcasting technology of the producing and broadcasting mechanism of the television program in the broadcasting and TV field, specifically referring to an unmanned distributed multi-threading caption rendering and broadcasting method. The method constructs a rendering working station group, distributes different rendering tasks on each working station by means of pre-setting, renders the caption contents of different types, respectively, then distributes an information processing working station to integrally monitor the rendering state of each working station and collects the error information and processes. This invention improves the working efficiency of the caption rendering, thereby making the caption technology develop towards to the direction of more stabilization, safety and high efficiency.

Description

technical field [0001] The invention relates to a subtitle broadcasting technology of a TV program producing and broadcasting institution in the radio and television field, in particular to an unattended distributed multi-threaded subtitle rendering and broadcasting method. Background technique [0002] From the perspective of specific implementation, the data structure of TV subtitles is very complicated, so the algorithm for realizing subtitle rendering is also very complicated. The main reasons are as follows: [0003] (1) Television stations have more and more requirements for subtitle effects. As a form of TV programs, subtitles have an independent ideographic function. It not only completes the basic function of explaining the content with text symbols, but also adds luster to the program content through the creation of special effects and animation. The content (text) of the subtitles, the attributes of statically rendered subtitles (font, color, etc.), and the attr...
