Problems solved by technology

[0013] Third, the human workload is huge, but the result is half the effort, which is not in line with the general trend of IT technology development
[0014] Fourth, from the perspective of probability and statistics, evaluation use cases with subjective experience characteristics cannot cover all logical branches of a system, so that it is impossible to objectively and accurately evaluate all the performance of a product. Even if a conclusion can be drawn, it is still a mistake. Biased

Embodiment Construction

[0054] The present invention will be further described below in conjunction with the embodiments and the accompanying drawings.

[0055] The template-based subtitle rendering efficiency statistical method of the present invention is based on the following technical principle: First, from the perspective of probability and statistics, the rendering time of subtitles can only be counted through the time of multiple rendering processes to obtain an average rendering time , this time value is objective and accurate; secondly, although there are many rendering attribute parameters in a subtitle system, the rendering time will be different due to different rendering attributes, but you can use the subtitle template made by the subtitle system to cover All rendering attribute parameters, so that the statistics of subtitle rendering efficiency are more objective and accurate.

Abstract

The invention discloses a template-based statistical method of caption rendering efficiency, and belongs to the technical field of the caption editing and broadcasting of television program making and broadcasting mechanisms in radio and television broadcasting field. The method for assessing the caption rendering efficiency in the prior art is mainly based on the subjective evaluation and has the shortcomings of inaccurate assessment result, heavy workload and the like. The method firstly creates a rendering source model library and a rendering attribute model library according to a plurality of caption templates; caption objects are created according to rendering sources in the rendering source model library and rendering attributes in the rendering attribute model library; all the created caption objects are rendered, the rendering time of each caption object, the total time of the rendering and the total times of the rendering are recorded; and the rendering efficiency is calculated according to the rendering time of each caption object, the total time of the rendering and the total times of the rendering. The use of the method can more accurately calculate the caption rendering efficiency and simultaneously calculate the impact factors of the rendering attributes on the rendering efficiency more accurately.

Description

technical field [0001] The invention belongs to the technical field of subtitle editing and broadcasting by TV program production and broadcasting institutions in the field of radio and television, and in particular relates to a template-based statistical method for subtitle rendering efficiency. Background technique [0002] With the development of the TV industry, the role of TV subtitles in TV is becoming more and more important, the average number of daily broadcasts is increasing, the forms of subtitles are broadcast in various forms, and the production of subtitles is also more exquisite. Through TV subtitles, we can make full use of the limited TV screen space to convey more information, so that viewers can more quickly understand new viewing dynamics, understand TV content, and improve viewing quality. At the same time, subtitles are also convenient for channel program packaging and enhance the overall image. And it can also interact with the audience and provide va...
