Abstract
The invention discloses a kind of television sets adaptively adjusted based on keyword volume, the sound of environment where setting microphone acquires television set on a television set, the voice signal of television set sending is obtained after weeding out noise, then judge that there are keywords in the voice signal, and if so, choosing first keyword in voice signal, the volume for calculating itself preset volume and its volume in the voice signal is poor, and then the broadcasting sound size of television set is adjusted according to the volume difference.The configuration of the present invention is simple, easy to use, user experience is good, needs ceaselessly to manually adjust the sound of each TV station when avoiding television tuning.
Description
Technical field
The present invention relates to field of television more particularly to a kind of television sets adaptively adjusted based on keyword volume.
Background technique
Television set is the common name of " TV-signal receiver ", is the device of receiving television broadcasting, by complicated electronic circuit
It is formed with loudspeaker, fluorescent screen etc..It is the composite video signal of TV station's transmitting to be received by antenna, then pass through electronic circuit that it, which is acted on,
Vision signal and audio signal are isolated, image and sound are reduced to by fluorescent screen and loudspeaker respectively.Television set has black and white electric
Depending on machine and two kinds of colour television set, there are also the functions of restoring color for colour television set.
TV signal is completed from point to the sequential sampling in face, transmission and reproduction by scanning.The television scanning of various countries
Standard is not quite similar, and is 25 frame per second in China, every 625 row of frame.Every row from left to right scans, and every frame is divided from top to bottom by interlacing
Odd-numbered line, even number line two swept, to reduce flicker perception.Image information is transmitted in scanning process.When scanning beam from
Lastrow trace terminates the line retrace return line back to before next line starting point and every has been swept from top to bottom, returns to
The field flyback return line in face should give blanking.Field blanking interval of being expert at transmits row field sync signal, keeps the scanning of sending and receiving same
Step, accurately to reappear original image.
Telephotography is the photoelectricity of target surface each point on photosensitive (or light guide) target surface for focus on the light image of scenery pick-up tube
The excitation or photoconductive situation of change of son are different with the brightness of light image each point.When being scanned with electron beam to target surface, that is, generate
One amplitude proportional is in the electric signal of each point scene light image brightness.The scanning electricity for making crt screen is transmitted in television receiver
Beamlet becomes with the power of input signal.When with transmitting terminal synchronous scanning, the original of transmission is shown on the screen of kinescope
Image.
The process of television signal transmission distribution, for relaying the fact in other cities, generally from video camera, TV
The heart or mobile control room, then through microwave relay link, transmitting station, finally arrive user's television receiver.In addition, telecasting satellite and electricity
Cable television is also national respectively and the effective means of urban area property television transmission distribution.
Television devices as one of widely used consumption electronic product, have been obtained it is deep universal, spy be with
The development of smart television, function breached traditional sense, develop to network, trip from single TV programme push
The functions such as play, various expanded applications.Smart television is more more and more universal as a kind of novel television devices, in Android system
Under TV transplanting trend, the function that television devices have also becomes increasingly complex, due to existing television devices have screen it is big,
The advantages such as clear, user no longer watch TV programme merely by television devices, it might even be possible to be stepped on by television devices
The more resource unrelated with TV programme of land internet browsing.
The market penetration rate of smart television in 2013 is 50%, it is contemplated that the smart television total market size is up to 3128 within 2014
Ten thousand, permeability will also be promoted to 69%.With constantly improve for smart television, the development of multi-screen interactive technology, smart television by
Gradually become the new lover of consumer, this also causes the change of home audience habit therewith, and it is most important that intelligent large-size screen monitors become family
Recreation terminal, relative to mobile phone and computer, people prefer to appreciate high-definition movie, TV with large screen.
The sound of existing television set is typically all to adjust by artificial, especially when adjusting platform, due to each TV
The sound of platform is of different sizes, needs constantly to adjust, cumbersome.
Patent " TV set sound volume control method and system " (application number: 201410181442.0 applyings date: 2014-04-
30) a kind of TV set sound volume control method and system are disclosed, display field is related to, it is unexpected to be able to solve sound when opening TV
It releases and the problem of the alarming other people that give great volume, the TV set sound volume control method of the invention is that television set is receiving open command
Afterwards, the process for executing " mute start-up mode ", specifically includes: obtaining system time and judges whether the system time stops default
Cease the period；If judging result is in the default rest period, television set carries out mute starting；If judging result is not stop default
The period is ceased, then television set is normally started.
The patent still needs artificially to be executed " mute start-up mode ", cannot substantially automatically adjust television sound volume.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of based on pass for defect involved in background technique
