Method for performance guarantee of television subtitle playing apparatus based on diversity application

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 a method for guaranteeing TV caption broadcasting device performance based on diversity application. The method uses a random number generator based on the data structure of the caption broadcasting system, simulates the practical application environment, automatically constructs the objects of picture and caption, then uses the caption to render an engine, performs multi-threading automation static rendering and dynamic special rendering to the caption, at the same time records the use condition of the system resource so as to monitor the defect of the logic design of the caption rendering, and to guarantee the safety, instantaneity and stability of the caption broadcasting system.

Description

technical field [0001] The invention relates to a subtitle broadcasting technology of a television program producing and broadcasting institution in the field of radio and television, in particular to a method for guaranteeing the performance of a television subtitle broadcasting device based on diverse applications. Background technique [0002] As an essential TV program element, TV subtitles are an important display form of TV graphics. With the subdivision of TV channels and program content, the division of labor of various departments has become more specialized. For the production of different types of programs, it is difficult to meet the requirements with a single type of subtitle system. In addition, the increasing diversity of TV programs and the continuous improvement of TV viewers' appreciation and appreciation level also require that the application mode of TV subtitles must develop in the direction of diversity. [0003] From the perspective of program charact...

Problems solved by technology

[0031] Even if a large number of test cases are designed, theoretically, all branches of the core rendering algorithm cannot be covered;

[0032] In the process of manual testing, the analysis of system resource occupation is often ignored, especially CPU usage and memory leaks, which cannot truly guarantee the real-time performance of subtitle playback
