Video subtitle processing method and guide system

Abstract

A video subtitle processing method and a guide system. The method comprises: obtaining subtitle data; rendering the subtitle data on a first preset subtitle template of a display area of a preset application to generate a fill signal picture, wherein the display area further comprises a second preset subtitle template, the second preset subtitle template is a key signal picture corresponding to the fill signal picture; and transmitting the fill signal picture to the guide station, and transmitting the key signal picture to the guide station, so that the guide station synthesizes the video stream to be displayed according to the fill signal picture and the key signal picture and obtain a new video stream. By using the preset application on the computer to realize the filling signal screen and the key signal screen, the online loading of the subtitle data can be achieved without the need to purchase a dedicated subtitle machine, which reduces the hardware cost, and with the flexibility of the preset application, the degree of automation of the subtitle processing is high, real-time performance is strong, the degree of freedom is high, and the application range is wide.

[0002] In the field of TV broadcasting, non-linear video editing equipment is widely used to produce and arrange subtitles. Non-linear video editing equipment uses an offline method to edit subtitle content and play it at a specified time. This method is costly and cannot meet real-time requirements.

Faced with a high-real-time live broadcast scene, when the subtitle content can only be provided temporarily, the staff usually use the subtitle machine system to make live subtitles, and then play according to the director's instructions. However, manual production and playback on the spot are prone to errors, and it is difficult to meet the data Scenarios with frequent item updates and many data items

In related technologies, there are still some webcasting software, such as OBS, which directly superimpose subtitles and video on different layers of windows, and then capture the superimposed results. However, the superimposition effect of such subtitles and videos is relatively simple, and the output quality cannot meet broadcast level requirements

In addition, in some subtitle processing schemes, bullet chatting technology is used to obtain new bullet chat content from the server, and the new bullet chat content is displayed on the top of the video screen, and the bullet chat is presented above the video on the playback side. This subtitle processing method is not in the video source Back-to-back synthesis at the end, unable to meet broadcast-level requirements
