Description
Technical field
The present invention relates to TV control field, particularly relate to a kind of intelligent TV set of automatic switch.
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.
When TV is from black-and-white TV to color TV transition, have employed compatible way, PAL-D continues into the present built in China always.From simulated television to high definition digital television transition, it is the transition of a great-leap-forward, cannot be directly compatible, that is all simulated televisions are non-serviceable, so it is unpractical for settling at one go, various countries have employed the way of a transition type--and both top box of digital machines, thus effectively avoids interference and loss that TV signal causes in transmitting procedure, the signal quality of television reception obtains and improves significantly.This is a kind of transition, because the scan line of simulated television is fixed, so it is compared with high definition digital television, also has sizable distance.
Digital TV set-top box is a kind of conversion equipment digital television signal being converted to analog signal, digital TV set-top box has become a kind of embedding assembly equipment, there is perfect real time operating system, powerful CPU computing capability is provided, be used for cooperation control Set Top Box each several part hardware facility, and easy-operating graphic user interface (Graphical User Interface is provided, GUI), as the electronic program guides of enhanced-quality television, provide the program description and background information that both pictures and texts are excellent to user.It is also a kind of Domestic electrical equipment of expansion functions of television set, be responsible for the various information (comprising TV programme) received to be converted to television set can the form of reality show on screen, simultaneously, ability that Set Top Box has " fool's computer ", bidirectional rebuilding is carried out a little like this by house software function with to network, being easy to realize as many services such as internet browsing, video request program, household electric business, telephone communications, is that a net is seized state power.
2010, China's digital TV set-top box industry came into the market the prosperity period of structural adjustment and deeply development.Within 2010, be 1 year of the fast development of China Digital TV Set Top Box, industry market stable development.National statistics office data shows: within 2010, the above digital TV set-top box enterprise of scale amounts to 317; Assets amount to 211.34 hundred million yuan; Enforcement sale takes in 214.48 hundred million yuan, increases by 30.65% on a year-on-year basis; The total value that earns a profit 10.92 hundred million yuan.
Along with constantly popularizing of digital TV set-top box, it will change the concept of our existing TV, also a brand-new consumption terminal will be provided for the Internet, and this consumption terminal will than other any terminals as PC, mobile phone, PDA all popularize, facilitate, attractive, because top box of digital machine is not only user terminal, or the network terminal, it can make simulated television turn to interactive digital TV (as video request program etc.) from passive reception simulated television, and can enter the Internet, make user enjoy the omnibearing information services such as TV, data, language.Some people thinks that Set Top Box is just used to make TV set internet, and this is the mistaken ideas in a kind of understanding.In fact, top box of digital machine is one of forming member of broadband integration information network before walking universal digital television.Along with the development of digital technology, multimedia technology and network technology, the built-in and whole cost of top box of digital machine will be impelled to decline, allowing most of user realize on general analog television machine can amusement, the many services such as to surf the Net again.
Whether people more and more enjoy Set Top Box and television set coordinates the superior life brought, but people, when using them, need and successively turn on Set Top Box and television set, and when closing them, no matter remote control, need again successively to close them.That is, people need to do twice breakdown action in use, need to do twice closing motion, trouble very when stopping using.
Patent " can automatic shutdown intelligent television " (application number: 201010603173.4 applyings date: 2010-12-24) discloses one can automatic shutdown intelligent television, primarily of TV and remote controller composition, remote controller is provided with a timer and liquid crystal display, timer sets the unused time by liquid crystal display, timer is connected with an Audio Players, Audio Players can be selected to open or close pattern, after the timer setting unused time, Audio Players can be opened when needing, during to the unused time, Audio Players can send prompt tone, on television screen, there will be shutdown simultaneously confirm interface, if do not operated within the time arranged, TV will give tacit consent to automatic shutdown, remarkable result of the present invention is provided with Audio Players, be conducive to better playing reminding effect, and Audio Players can also switch to silent mode, can when do not affect people have a rest automatic shutdown.
This method is by artificially manually setting the unused time, just closes TV, can not open and close automatically television set according to the state of Set Top Box to the unused time.
Existing television set does not generally possess the function of call user's attention protection eyes, can not take measures when user closely sees TV for a long time.Teenager viewing TV in, often unconsciously just from TV very close to, if long-term habits is bad, be easy to cause damage to teen-age eyesight.
Patent " has the television set of vision protection function ", and (application number: 201010540311.9 applyings date: 2010-11-11) discloses a kind of television set with vision protection function; it comprises tv shell; the outer surface front of described housing arranges several illuminating lamps, and described illuminating lamp is 4-20.This invention arranges illumination lamp by face on a television set, effectively can protect the eyes of the people of viewing TV, be beneficial to and apply.
This mode protects eyes by strengthening isolation light between human eye and TV, but still can not solve eyes of user distance TV excessively closely causes VI problem.
