Abstract

The invention discloses a video virtual hand language system facing a digital television. According to the system, de-multiplexing is carried out on a program source code stream, and voice, video and other data information are decoded, wherein other data information comprises caption text information; a caption text is inputted into a virtual hand language generation module which calls corresponding hand language data from a hand language database according to a text entry and carries out figure drafting to generate a hand language frame, and proper smooth processing is carried out between different gestures; and the hand language frame and voice information of a program are subjected to synchronous superposition and outputting. Through the video virtual hand language system, manpower and material resources are saved and preparation is standard, simultaneously, the smooth processing based on content is employed, motions of a gesture is natural, cooperation of face expression and the gesture is introduced, and gesture expression is more accurate and in accordance with reality.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a digital television-oriented video virtual human sign language system. Background technique [0002] There are nearly 30 million deaf-mute people in China, and it is a major popular project to solve the problem of the deaf-mute watching TV. At present, most TV stations do not have channels suitable for the deaf-mute to watch. Some news programs use manual recording to complete the sign language conversion, which not only consumes a lot of manpower and material resources, but also lacks timeliness, accuracy and standardization of sign language. . [0003] Sign language recognition and sign language synthesis research have made great progress in recent years, and sign language systems based on virtual humans have also been initially applied, and trials have begun in many public places. For example, Vcom3D has developed software that allows people to communicate with o...
