Problems solved by technology

[0004] Another situation is that when people are enjoying audio-visual works (such as listening to MP3 music, TV dramas, etc.), sometimes they really want to know the background information of the work. Now some programs use the method of displaying subtitles on the screen or the way of voice-over. The goal is achieved, but the user cannot turn off the voice-over, which affects people who do not need voice-over, so similar voice-overs cannot appear too much in the program

Embodiment Construction

[0015] This proposal is to improve the signal processing method and system equipment of audio-visual program production and broadcasting.

[0016] The implementation steps are: increase equipment configuration→separately record dubbing of program screen→add dubbing into main program signal→transmit and store program→separate dubbing signal during program playback→process and output the dubbing signal.

[0017] The first is the improvement of audio-visual program signal production, including the use of program production equipment and software.

[0018] from figure 1 It can be seen that it includes a basic circuit configuration for digital film and television program production, in which the dubbing recording microphone 101 and dubbing recording processing circuit 102 are additional configurations on the basis of the original equipment, and the original program recording equipment can be borrowed for dubbing recording. The commentary dubbing signal recorded by the recording mi...

Abstract

The invention discloses a multifunctional video program signal processing system, which modifies video program manufacture and play methods and system devices, and especially resolves the enjoy problem of blind mans on video programs. The multifunctional video program signal processing system comprises the circuits as a dubbing recording microphone, a dubbing processing circuit, a dubbing signal modulation coding circuit, a dubbing demodulation and decoding circuit, a switch circuit, a dubbing output circuit, a wireless transmission device and an earphone and the like. The invention adds a signal into the signals of video program, therefore, blind man and normal people can enjoy one program without affecting each other, the effect is that blind man is assisted by a volunteer which explains program, and normal people has an additional way to enjoy program as off-screen voice.

Description

Technical field [0001] The invention relates to a multi-functional audio-visual program signal processing system. Background technique [0002] Audio-visual programs have greatly enriched people's spiritual and cultural life. People see images with their eyes and listen to sounds with their ears, which is very common, but it is very difficult for the blind. They have no eyesight and are eager to perceive rich audio-visual programs with their sense of hearing. [0003] At present, there are probably two ways for blind people to better appreciate audio-visual programs. One is that volunteers accompany blind people to watch movies and TV, and explain the content of the screen to blind people. This method is very popular among blind friends, but it is impossible for volunteers to accompany them every day. Every ordinary blind person watches movies and TV. In addition, there is another kind of online video, which is to explain and dub the screen, and it is specially provided fo...
