Problems solved by technology

[0004] Most of the current domestic virtual host programs are generally non-real-time, and a lot of work needs to be completed through post-production, which cannot meet the real-time requirements of sign language news in the radio and television system. Program production must have real people performing to drive virtual people, so it needs to invest a lot of manpower and material resources

Embodiment Construction

[0036] The present invention is a system and method for overlaying sign language subtitles of a video avatar based on the following two technologies that have been publicly reported.

[0037] Among them, one is: virtual human synthesis technology [see "Journal of Computer-Aided Design and Graphics", No.1, 2004, "A Method for Generating a Personalized Virtual Human Model Skeleton", Research on Human Modeling Based on VRML, Computer Journal of Simulation, Issue 1, 2004 and http: / / vh.ict.ac.cn, etc.], this technology realizes the synthesis and display of a virtual human on a computer. The other is: Chinese Sign Language Synthesis Technology [see "Journal of Software", Vol.13, No.10, "Chinese Sign Language Synthesis Method Based on Virtual Human Synthesis Technology", http: / / sy.jdl.ac.cn, etc.] , which enables the translation of text into Standard Chinese Sign Language.

[0038] The main function of the invention is to automatically translate program text content into sign langua...

Abstract

The system comprises: a video signal inputting device; a video signal outputting device; and a central computing device. The central computing device comprises a sign language synthesis module for in translating the inputted program text into sign language data; a virtual man synthesis module for expressing the sign language data by using the virtual man; a non-linear editing card supporting image overlapping function; a voice time length synchronous information acquiring module for recording the initial time and ending time of each sentence text; a main module for controlling the sign language synthesis module to translate the program text into the sign language data that is expressed by the virtual man synthesis module, then controlling the non linear editing card to overlap the sign language image into the program bit-stream, and then to output to the outputting device.

Description

technical field [0001] The invention relates to a video program production technology, in particular to a video program virtual human sign language editing system. Background technique [0002] my country's TV network has developed rapidly and is now very developed. There are more than 1,000 TV stations at all levels with a certain coverage and economic strength. These TV stations have their own news and special programs and even news channels. There are a considerable number of deaf-mute or hearing-impaired people in their audience. Considering the viewing needs of this group of people, many TV stations have launched sign language news and other columns. , but the current method is to complete the sign language conversion by manpower, and add sign language display when the news is rebroadcasted. Therefore, there are many shortcomings in terms of timeliness, accuracy and standardization of sign language. Although some recent TV dramas and TV programs try to provide convenie...
