Abstract
The invention discloses a television with a function of adaptive volume adjustment in channel switching. The television comprises a television body, a voice sensor and a control module. The voice sensor is used for sensing indoor voice volume; the control module comprises a voice computation unit, a volume adjustment unit and a volume control unit; the voice computation unit is used for computing a difference value between a preset volume threshold and the indoor voice volume; the volume adjustment unit is used for adjusting volume of the television; the volume control unit sets the channel volume to zero after channel switching and increases the channel volume according to a preset volume increment until an absolute value of the difference value between the preset volume threshold and the indoor voice volume is smaller than or equal to a preset difference threshold. The television with the function of adaptive volume adjustment in channel switching is simple in structure, convenient to use and capable of automatically adjusting the volume when a user switches channels so as to provide the user with excellent user experience.
Description
Technical field
The present invention relates to television set control field, particularly relate to a kind of television set of automatic regulating volume when adjusting platform.
Background technology
Television set is the common name of " TV-signal receiver ", is the device of receiving television broadcasting, is made up of the electronic circuit of complexity and loudspeaker, phosphor screen etc.Its effect is the composite video signal being received TV station's transmitting by antenna, then isolates vision signal and audio signal by electronic circuit, is reduced to image and sound respectively by phosphor screen and loudspeaker.Television set has black and white television set and color television set two kinds, and color television set also has the function of reduction color.
TV signal has been come from point to the sequential sampling in face, transmission and reproduction 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 by interlacing, swept, in order to reduce flicker perception from top to bottom by point odd-numbered line, even number line two.Image information is transmitted in scanning process.When scanning beam terminates the line retrace return line before turning back to next line starting point from lastrow trace, and every has been swept from top to bottom, and the field flyback return line got back to above all should give blanking.Field blanking interval of being expert at transmits row field sync signal, makes the scan-synchronized of sending and receiving, to reappear original image exactly.
Telephotography is focused on by the light image of scenery on photosensitive (or photoconduction) target surface of camera tube, target surface each point photoelectronic excite or photoconductive situation of change different with the brightness of light image each point.When scanning target surface with electron beam, namely produce an amplitude proportional in the signal of telecommunication of each point scene light image brightness.Be sent in television receiver and the scanning beam of crt screen is become with the power of input signal.When with transmitting terminal synchronous scanning, namely the screen of picture tube manifests the original image of transmission.
The process that television signal transmission distributes, to relay the fact in other cities, generally from video camera, television operating center or mobile control room, then through microwave relay link, transmitting station, finally arrives user's television receiver.In addition, telecasting satellite and cable TV are also national and the effective means of urban area property television transmission distribution respectively.
Television devices is as one of widely used consumption electronic product, obtain deep popularizing, spy is the development along with intelligent television, and its function breaches traditional sense, pushes develop into the functions such as network, game, various expanded application from single TV programme.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, because existing television devices possesses the advantages such as screen is large, clear, user watches TV programme by television devices, even can browse more resources irrelevant with TV programme by television devices internet login.
The market penetration rate of intelligent television in 2013 is 50%, and estimate that the intelligent television total market size in 2014 will reach 3,128 ten thousand, permeability also will be promoted to 69%.Constantly perfect along with intelligent television, the development of multi-screen interactive technology, intelligent television becomes the new lover of consumer gradually, this also causes the change of home audience custom thereupon, 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 large-screen.
The more and more hommization of existing intelligent television, the function possessed also gets more and more.But, some places are still had not consider: during existing television boot-strap, the volume of preserving when the volume of each channel is last this channel of viewing, sometimes when switching channels, the channel be switched to can send very large sound, bad Consumer's Experience is caused to user, even can frighten user, and the sound of the channel sometimes switched is little especially, needs again user manually to go adjustment, user when ceaselessly zapping finds the program oneself liked, inconvenience very.
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, sound when opening TV can be solved release suddenly and other people problem of agitation that gives great volume, 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 comprise: 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 method only judges whether quiet startup according to system time, start even if quiet, also there is very large deficiency, on the one hand, need after quiet startup artificially manually to adjust volume, inconvenience very, on the other hand, quiet startup only relates to the startup of TV, when carrying out channel switch to TV, can send the phenomenon of very large sound after still there will be switching channels.
