Embodiment Construction

[0028] The invention provides a method for streaming video subtitles to realize real-time superimposition of video resources and subtitle information in a system. The method can realize the real-time overlay display of subtitles and videos in a certain area, and can also realize the real-time overlay of subtitles and videos when cross-region on-demand. The technical solution of the present invention will be further described in detail below.

[0029] The system is equipped with subtitle server, regional service center, management terminal and display terminal in each region. The subtitle server is responsible for storing the subtitles and related information set by the user; the regional service center is responsible for scheduling and forwarding various instructions, audio and video data and subtitle data; the management terminal is responsible for the configuration of various parameters of the system, including the configuration of subtitle related parameters; The display t...

Abstract

The invention discloses a fluidization method for video subtitles. The method includes the steps that the subtitles which need to be superimposed are set and stored on subtitle servers of service centers of all areas; a needed video is played in an on-demand mode; a subtitle superimposing instruction is sent to the subtitle servers; the subtitle servers extract subtitle information matched with a real-time video from stored subtitle information, and fluidization processing is conducted; corresponding video streaming data frames are matched according to the subtitle information; subtitle streaming data and the video streaming data are synchronized, and uniform data streams are formed; the subtitle servers are used for transmitting the synchronized video streaming data and subtitle streaming data to a display terminal; the display terminal is used for conducting decoding display. According to the fluidization method for the video subtitles, the subtitle information of front-end equipment is not synchronized in a whole network mode any more, data synchronizing work is reduced, and the system management efficiency is improved. The video broadcasted in the on-demand mode and the subtitles are synchronously transmitted, the real-time performance of subtitle superimposing is enhanced, and the user experience is promoted. The service center of each area only manages the subtitle information of the front-end equipment in the corresponding area, and management is more flexible and more convenient.

Description

technical field [0001] The invention belongs to the field of video processing, and more specifically relates to a method for streaming video subtitles, which is suitable for superimposing dynamic subtitles on real-time display images and can ensure the synchronization between subtitles and images. Background technique [0002] In recent years, systems such as video surveillance, video conferencing, and video command have been widely used in the fields of industry, transportation, commerce, finance, military, and security. Visual business systems have become one of the important means of modern management, monitoring, and control. Superimposing real-time subtitles on the display image of the video system is a common practice for various video service system prompts and auxiliary image display content. Traditional subtitle superimposition is to store the subtitle information to be superimposed in the database through the user terminal, and when the image corresponding to the s...
