Abstract

The invention relates to a single-layer displaying method and device of subtitle data. Only one work layer needs to be generated when multiple lines of subtitle data are displayed, color index data of all subtitles are written into the work layer, and then corresponding color values are obtained from corresponding virtual color palettes according to the color index data so that the subtitle data to be displayed can be generated in advance. The subtitle data can be conveniently and timely called in real time when the data need to be used, cost is saved to some extent, and efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a single-layer display method and device for subtitle data. Background technique [0002] With the development of science and technology and the needs of users, more and more TVs are equipped with subtitle systems. The subtitle data in the TV is transmitted through TS streams. Each piece of subtitle data received by the TV contains multiple lines of subtitle data. . When displaying multiple lines of subtitle data in the existing data, each line of subtitle data corresponds to a working layer, and each working layer corresponds to a display layer. When displaying, each line of subtitles to be displayed and the corresponding subtitles of each line of display subtitles are generated in real time. Virtual palette, low display efficiency. Contents of the invention [0003] The main purpose of the present invention is to provide a single-layer display method and device for subt...
