Abstract

The present application discloses a subtitle display method and a display device, which are used to estimate the processing duration of subtitles to be processed according to the processing duration of subtitles that have been processed, and use the processing duration of subtitles to be processed as a time offset. The subtitles to be processed are processed before the display start time of the subtitles to be processed, so as to reduce subtitle display errors. The method includes: during the video playing process, obtaining data of a subtitle from a queue storing subtitle data, the data of the subtitle includes display start time; The processing duration of the M subtitles is calculated to process the required duration of the subtitles; the display start time of the subtitles is utilized to subtract the calculated processing duration of the subtitles to obtain the processing start time of the subtitles; When the video playback time reaches the processing start time, the subtitle is rendered and drawn, so as to display the subtitle on the display.

Description

Technical field [0001] The present application relates to the field of display technology, in particular to a subtitle display method and display device. Background [0002] With the development of multimedia technology, display devices can not only play audio and video, but also often accompanied by subtitle display. [0003] The traditional subtitle processing process is to render and draw the subtitle when the video playback time reaches the starting time of the subtitle display, and after the drawing is completed, the user can see the subtitle through the monitor. Due to the long rendering and drawing time, there is a delay in the display of subtitles, and the display error is large. Contents of the Invention [0004] The present application provides a subtitle display method and display device, for estimating the processing time of the subtitles to be processed according to the processing time of the subtitles that have been processed, and the processing time of the subtitl...
