Description
Technical field
The present invention relates to field of set-top, particularly relate to a kind of start and automatically select the Set Top Box of channel.
Background technology
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.
It is all the channel given tacit consent to that existing Set Top Box is generally started shooting, and cannot select channel according to the use habit of user.
Patent " a kind of demodulation of Set Top Box and tuning self-adaptation drive method " (application number: 201410329272.6 applyings date: 2014-07-11) discloses a kind of demodulation of Set Top Box and tuning self-adaptation drive method, belong to technical field of digital television set-top, the data configuration being stored adaptive region by change Set Top Box FLASH can adapt to various hardware platform, comprises the following steps:
1). before set-top-box opening startup enters system, first loading LEN from the adaptive region of Set Top Box FLASH is the self-adapting data of 32BYTE;
2). take out the value of BYTE0, BYTE1, BYTE2, BYTE3 respectively, represent demotype respectively, tunertype, tsmode, tsedge, call different demodulation by demotype again and drive code, the demodulation different by adaptive allocation drives, to realize the different demodulation of same version softwarecompatible and tune drive;
3). in different demodulation drives, complete tunertype, the configuration of tsmode, tsedge;
4). when Set Top Box electrifying startup completes, more normally start other codes.
This invention achieves only needs same version set-top box software just to go for various hardware platform, achieves the versatility of software application.But this invention cannot collect the interest channel of user in each time period, the channel that cannot automatically select user most interested within this time period when starting shooting.
