Sound can be translated into the television set of captions
Technical field
The utility model belongs to television set, relates in particular to a kind of television set that can translate into sound captions.
Background technology
The television channel that we can watch is more and more, comprises nternational Channel or foreign film.But often run into the situation that does not have captions, bring very big puzzlement to the user.The world is exactly the global village, and market demands developing a kind of TV urgently, and which country language what no matter play is, as long as the user enters the captions preference pattern, selects the language that oneself needs, just can show the captions of correspondence below screen synchronously.Certainly, when the user did not select, this function did not start, and it is constant that TV is kept original function.
The utility model content
The utility model is in order to overcome deficiency of the prior art, a kind of television set that can translate into sound captions is provided, utilize the audio files analysis module from the voice data that receives, to extract the related sound code and send to translation module, translation module sends to display device to the text file that translation is finished again, promptly can become literal to audio conversion, also can translate into the country variant language and be presented at the screen below according to user's needs.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of television set that can translate into sound captions, the motherboard circuit that comprises television set, it is characterized in that: described motherboard circuit increases sound and translates into caption circuitry, described sound is translated into caption circuitry and mainly is made of the audio files analysis module, FLASH dictionary module and the translation module that connect successively, and described sound is translated into caption circuitry and is connected with CPU.
Be connected with filter between described audio files analysis module and FLASH dictionary module and the translation module.
Described translation module is connected with display device.
Beneficial effect: utilize the audio files analysis module from the voice data that receives, to extract the related sound code and send to translation module, translation module sends to display device to the text file that translation is finished again, promptly can become literal to audio conversion, also can translate into the country variant language and be presented at the screen below according to user's needs.

Embodiment
Below in conjunction with preferred embodiment, details are as follows to embodiment that foundation the utility model provides.
See accompanying drawing for details, a kind of television set that can translate into sound captions, the motherboard circuit that comprises television set, described motherboard circuit increases sound and translates into caption circuitry, described sound is translated into caption circuitry and mainly is made of the audio files analysis module, FLASH dictionary module and the translation module that connect successively, and described sound is translated into caption circuitry and is connected with CPU.Be connected with filter between described audio files analysis module and FLASH dictionary module and the translation module.Described translation module is that display is connected with display device.
See Fig. 1 for details, hardware circuit design
Add audio files analysis module and translation module on TV.When the user needs this function, enter the captions preference pattern, select " Chinese subtitle " " English subtitles " or " Korean captions " or the like.When CPU received the order of caption demonstration, the audio files analysis module began to extract the sound code, and filters unnecessary noise and interference by filter, only stays voice.Filter can be used the LPF(low pass filter) realize.The voice code enters the audio frequency comparison database, translates the selection of dictionary, such as " English to Chinese dictionary ".After selection is finished, begin corresponding sound code is translated.Here need use a FLASH Memory, capacity is that the MX25L4005 of 4Mbit promptly can realize on the market.The sound code that translation is finished is implemented in the sychronization captions demonstration of screen below again with regard to the spoken and written languages of respective user appointment by display device.
See Fig. 2 for details, software flow
Audio files analysis module function can realize that for example present absolute video can be realized this function to audio converter (Absolute Video to Audio Converter) or total video converter (Total Video Converter) by software.In order to remove irrelevant sound and big noise, need hardware to add low pass filter, i.e. LPF is by being voice behind the LPF.Voice will enter the audio frequency comparison database after extracting, and defines the kind of current sound, again in conjunction with the language of user's appointment, determines that next target is " English to Chinese dictionary " or " Korea Spro translates Chinese dictionary " or other kinds.The sound code that translation is finished just can send display device to, carries out the demonstration of captions.Certainly,, and do not need to translate, when finding that after the audio frequency comparison database current sound kind and user's appointed language are language of the same race so, just saved this step of translation, be directly changed into literal and be presented on the screen if the user only needs the primary sound captions.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
