Description
Technical field
The present invention relates to STB network field of terminal technology, more particularly to a kind of integrated EOC and WIFI function are in one
Bi-directional set-top box.
Background technology
With the rapid development of science and technology, DTV comes into huge numbers of families, mainly lain fallow as family life
One of entertainment form, highly important role is all play in each age stratum.The function of TV is powerful all the more and extensive, especially
It is the functions such as abundant digital television broadcasting program, internet surfing, online receiving and dispatching mail, long-distance education, video conference, shadow
The life of people is rung, and changes the idea of people.In addition, with the development of internet, as long as terminal device can be realized
Function, such as Internet video, experience game, can equally be realized in general television set terminal.
As the basis and premise for realizing function that intelligent terminal can be realized, digital television set top box can not or
Lack.Set top box is a kind of device for extending functions of television set, in addition, set top box is not only user terminal, and the network terminal, profit
By the use of cable TV network as transmission platform, television set is user terminal, simulated television is turned to interactive mode from passive reception
DTV, user is allowed to enjoy the comprehensive information service such as DTV, digital broadcasting.
Broadcasting and TV bi-directional set-top box will realize the function of not only needing to have and watch DTV, and possess two-way interaction
Function.In network structure, bi-directional set-top box must possess two-way network communication module.The access side of broadcasting and TV bilateral network at present
Formula mainly has a modes such as LAN, EOC, CMTS, therefore according to the difference of access way, and bi-directional set-top box bi-directional communication modules can be with
There are the modes such as Switch, EOC, CMTS, can be independent external device or built-in module.
With the development of home control network communication protocol, wireless data transmission technology is further ripe, with Radio Transmission Technology
Constantly improve promote the extensive use of wireless connection.The function of set top box also will be more powerful, will be " a small intelligent
Change integrated computer ", in addition, set top box is no longer the device of an extension functions of television set, but connect family's sub-network
With the gateway of social big network, it is necessary to a kind of more flexible and user-friendly operation device, with realize user and DTV and
Intelligent interaction between set top box.So family's WIFI hot spot covering for family's mobile terminal seems very necessary.
Above mentioned problem is should to pay attention to and solve the problems, such as in the design of set top box and running.
The content of the invention
It is an object of the invention to provide a kind of integrated EOC and WIFI function in the bi-directional set-top box of one, to reach machine top
Box, which can be realized, watches digital television function, can also realize the effect of two-way interaction function, while solving family's movement
The problem of family's WIFI hot spot covering of terminal.
