Description

With the interconnected television set of wireless network
Technical field
The present invention relates to a kind of television set, the particularly a kind of and interconnected television set of wireless network.
Background technology
Television technologies has obtained bigger popularizing and development in recent years, people utilize various technological means to give more function for television set, make television set break away from the broadcast form of single receiving video signals and display video signal, become multi-functional household electrical appliance.For example, for television set increases USB interface and compressed image decoder (as the decoder of JPEG, MEPG1/2/4 reference format compressed image), the realization television set is connected with digital products such as digital camera, video camera, USB flash disk, MP3, can will decode in the multimedia file importing television set that be stored in the digital products such as digital camera, video camera and play, make people can utilize the large-screen of television set and good acoustics to appreciate from the digital information in the mobile digital product.
Along with development of internet technology, the resource on the wireless network is more and more abundanter, and again because many advantages such as the large-screen of television set, high image quality, person skilled begins to research and develop the technology of utilizing television set to browse and obtain affluent resources on the wireless network.At present, utilize TV set for browsing and the technological means of obtaining Internet resources to mainly contain following dual mode:
One, realizes the mode of TV set for browsing Internet resources by set-top box (STB, Set-top Box)
On television set, connect a set-top box with modulator-demodulator or network interface card, this set-top box and wireless network are interconnected under the support of software, the digital television business that set-top box receive to be authorized, Chinese demonstration, basic epg EPG (being TV guide), software upgrading, enciphered message prompting, paid service, data broadcasting, broadcast type video request program and local interaction business, television set by set-top box can satisfy video request program, functions such as the business that surfs the web, E-mail receiver/send, interactive game and IP telephone service.Though it is interconnected that set-top box can realize television set and wireless network, but set-top box all belongs to the category of basic model basically at present, use mainly and download based on data broadcasting, paid service and simple recreation, its interactive application only limits to local interaction, can't be applied in well in the business such as the transmitting-receiving of surf the web professional and Email and interactive game, and, purchase the set-top box cost also than higher for the user, it is also not too convenient to use.
Two, realize the mode of TV set for browsing Internet resources by built-in PCI wireless network card
The patent No. is 200420099126.0 Chinese patent " high-end television sets " (open date 2006.01.25, publication number CN2754294), discloses the television set that a kind of built-in PCI network interface card is realized browsing network resources.As shown in Figure 1, this patent is at an inner PCI wireless network card and the CPU of increasing of television set, the PCI wireless network card links to each other with CPU with clock bus by pci bus, control bus, and the PCI wireless network card links to each other with outside netting twine by network interface, just can realize the interconnected of television set and external network.The above-mentioned relatively first kind of mode of this mode effectively reduces cost, realized that television set and wireless network are mutual, the transmitting-receiving of can surf the web professional and Email and interactive game etc.But owing to developing rapidly of radio network technique, the home control network communication protocol standard also can be upgraded faster, wireless network card also can upgrade faster in order to adapt to new home control network communication protocol standard, when the user need upgrade wireless network card, this built-in wireless network card was difficult for upgrading, if must upgrade, just need to change television set, perhaps tear machine open by the professional and upgrade, this is cumbersome for most of user.
Summary of the invention
