Television set based on keyword volume self-adaptative adjustment
Technical field
The present invention relates to field of television, particularly relate to a kind of television set based on keyword volume self-adaptative adjustment.
Background technology
Television set is the common name of " TV-signal receiver ", is the device of receiving television broadcasting, is made up of complicated electronic circuit and loudspeaker, fluorescent screen etc..Its effect is to receive, by antenna, the composite video signal that television station launches, then isolates video signal and audio signal by electronic circuit, is reduced to image and sound by fluorescent screen and loudspeaker respectively.Television set has black and white television and color television receiver two kinds, and color television receiver also has the function of reduction color.
TV signal from the sequential sampling of point to face, transmit and reappear and complete by scanning.The television scanning standard of various countries is not quite similar, and is 25 frames per second in China, every frame 625 row.Often row from left to right scans, and every frame has been swept, in order to reduce flicker perception by interlacing point odd-numbered line from top to bottom, even number line two.Transmitted image information in scanning process.When scanning beam terminates the line retrace return line before returning to next line starting point from lastrow trace, and every has been swept from top to bottom, returns to field flyback return line above and all should give blanking.Field blanking interval of being expert at transmits row field sync signal, makes the scanning of sending and receiving synchronize, to reappear original image exactly.
Telephotography is to be focused on by the light image of scenery on photosensitive (or photoconduction) target surface of pickup tube, and target surface each point photoelectronic excites or photoconductive situation of change is different with the brightness of light image each point.When target surface being scanned with electron beam, i.e. produce an amplitude proportional in the signal of telecommunication of each point scene light image brightness.It is sent in radiotelevisor make the scanning beam of crt screen become with the power of input signal.When with transmitting terminal synchronous scanning, the screen of image reproducer i.e. manifests the original image of transmission.
The process of television signal transmission distribution, as a example by relaying the fact in other cities, typically from video camera, television operating center or mobile control room, then through microwave relay link, transmitting station, finally arrives user's radiotelevisor.Additionally, telecasting satellite and cable TV are national and the effective means of urban area property television transmission distribution the most respectively.
Television devices is as one of widely used consumption electronic product, have been obtained for deep popularizing, spy is as the development of intelligent television, and its function has breached traditional sense, pushes from single TV programme and develops into the functions such as network, game, various expanded application.Intelligent television is more and more universal as a kind of novel television devices, under the TV transplanting trend of Android system, the function that television devices possesses also becomes increasingly complex, owing to existing television devices possesses the advantages such as screen is big, clear, user is no longer merely by television devices viewing TV programme, it might even be possible to browse more resource unrelated with TV programme by television devices internet login.
The market penetration rate of intelligent television in 2013 is 50%, it is contemplated that within 2014, the intelligent television total market size is up to 31,280,000, and permeability also will be promoted to 69%.The most perfect along with intelligent television, the development of multi-screen interactive technology, intelligent television is increasingly becoming the new lover of consumer, this causes the change of home audience custom the most therewith, intelligence large-size screen monitors become the most important recreation terminal of family, relative to mobile phone and computer, people prefer to appreciate high-definition movie, TV with giant-screen.
The sound of existing television set is typically all to rely on and artificially regulates, and especially when adjusting platform, owing to the sound of each television station varies in size, needs constantly to adjust, cumbersome.
Patent " TV set sound volume control method and system " (application number: 201410181442.0 applyings date: 2014-04-30) discloses a kind of TV set sound volume control method and system, relate to display field, can solve the problem that when opening TV that sound is released suddenly and give great volume other people problem of agitation, the TV set sound volume control method of this invention is that television set is after receiving open command, perform the flow process of " quiet start-up mode ", specifically include: obtain system time and judge that whether this system time is in the default rest period;If judged result is that then television set carries out quiet startup in the default rest period;If judged result is that then television set normally starts not in the default rest period.
This patent needs for artificially carrying out performing " quiet start-up mode ", it is impossible to be substantially automatically adjusted television sound volume.
Summary of the invention
The technical problem to be solved is for defect involved in background technology, it is provided that a kind of television set based on keyword volume self-adaptative adjustment.
The present invention solves above-mentioned technical problem by the following technical solutions:
Television set based on keyword volume self-adaptative adjustment, comprises mike, signal receiving module, signal processing module, display module, speaker and control module;
Described signal processing module is connected with signal receiving module, display module, speaker respectively, and described control module is connected with mike, signal processing module, speaker respectively;
Described signal receiving module is used for receiving TV signal and passing it to described signal processing module;
Described signal processing module, for processing the TV signal received, is separated into picture signal and acoustical signal, and picture signal passes to described display module, and acoustical signal passes to described speaker and control module;
The picture signal that described display module receives for display;
Described speaker is for playing the acoustical signal received;
Described mike is for gathering the acoustical signal at television set place, and passes it to described control module;
Described control module comprises matching unit, comparing unit and regulation unit;
Described matching unit mates for acoustical signal and the acoustical signal received from signal processing module collected by mike, the acoustical signal that will collect is different from after the signal of the acoustical signal received from signal processing module weeds out, passes it to described comparing unit;
Described comparing unit is for mating default some keywords with the acoustical signal received successively, if there is keyword in the acoustical signal received, then choose first keyword of the acoustical signal received, calculate the volume itself preset poor with its volume of volume in the acoustical signal received, and this volume difference is passed to regulated unit;
Described regulation unit is for according to the volume difference regulation speaker received.
As the present invention further prioritization scheme of television set based on keyword volume self-adaptative adjustment, the processor of described control module uses AVR series monolithic.
