Summary of the invention

The utility model is in order to overcome television product function singleness in the prior art, can not better service in the deficiency of home entertaining, a kind of high-end television sets product is provided, realized the value-added service function of tv product, high-end TV has been finished by the transformation of simple display terminal to the entertainment service terminal, thereby increased the market competitiveness of like product.

For solving the problems of the technologies described above, the utility model is achieved by the following technical programs:

A kind of high-end television sets comprises CPU and audio-video interface circuit, and described CPU links to each other with a usb circuit by the standard interface data wire, and the realization television set is communicated by letter with outside movable storage device; In addition, described CPU is connected a network controller through pci bus, control bus and clock line, and its transmission, receiving port link to each other with a network interface; The data/address bus of CPU, address bus, control bus and clock line also are connected a DMA, by the radio communication between wireless network card realization television set and other equipment.

As a preferred embodiment of the present utility model, the standard interface of described USB interface chip links to each other with described CPU through data/address bus.

As another preferred embodiment of the present utility model, the transmitting terminal of described network controller links to each other with described network interface through a network isolation transformer with receiving terminal, and it is the isolating chip realization of GTS518 that described network isolation transformer adopts a model.

As another preferred embodiment of the present utility model, the pci bus of described CPU is converted into Min-PCI bus through a conversion module with pci bus with data/address bus and links to each other with described wireless network card.

It is the central processing element realization of Sunplus1001A that above-mentioned CPU adopts a model.

Compared with prior art, advantage of the present utility model and good effect are: the utility model is by setting up usb interface unit in existing television set module, network control interface unit and DMA DMA unit three part of module circuit, TV programme or DVD that existing television set not only can normal play TV and Radio Service be sent, the vision signal that media terminations such as VCD machine send, and possessed three kinds of value-added service functions, television set can be enjoyed come from the USB mobile device, on the broadband network and the audio and video resources on the far-end PC, realized that high-end TV by the transformation of simple display terminal to the entertainment service terminal, has increased the market competitiveness of like product.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

The television module that high-end television sets of the present utility model will have certain function is embedded in the high-end TV product, make high-end TV except having traditional TV functions, the value-added service function that has had other again, as USB function, wideband multimedia amusement function and DMA function, mainly be made up of several sections such as processor circuit unit, network interface unit, usb interface unit and audio frequency and video output unit, outside input units, its circuit theory diagrams are referring to shown in Figure 1.Wherein, CPU element partly adopts the primary processor of Sunplus1001A central processing element as whole system, and operating system adopts built-in Linux operating system, and the hard decoder of built-in MPEG1/2/4 is supported the various video coded format; The power supply power pack mainly is responsible for providing the power supply of each unit in the system and system kernel to supply with; The output of audio-video signal mainly is responsible in the audio-video interface unit, and the output of S terminal, the output of compound terminal and the output of YPbPr TV signal can be provided; Usb interface unit makes high-end television sets have the function of playing audio and video resources on the movable storage device; Network interface unit has realized the wideband multimedia amusement function, makes high-end television sets become a broadband entertainment terminal, can play the music and the video resource that come from the broadband; The DMA functional module is with wireless mode, the picture, music and the video frequency program that high-end television sets can be play be stored on the far-end computer.

Fig. 2 and Fig. 5 show the circuit theory and the connection layout of usb interface unit.Wherein, the power end VBUS of USB interface chip links to each other with+5V DC power supply through fuse F1, and standard interface end D-, D+ link to each other with CPU through data wire USB DM, USB DP, and VSS, G hold ground connection, have realized the USB function of television set.

Fig. 3 and Fig. 6 are the circuit theory and the connection layouts of network interface unit in the utility model.Wherein, it is the chip realization of DM9102 that network controller adopts a model, it links to each other with CPU with clock cable by pci bus, control bus, its transmitting terminal TXO+, TXO-link to each other with transmitting terminal TX+, TX-with receiving terminal RX+, the RX-of network interface RJ45 respectively through network isolation transformer GTS518 with receiving terminal RXI+, RXI-, thereby make the television set outside netting twine of can arbitrarily pegging graft, information resources on the playing network become the end product in family broadband.Network isolation transformer GTS518 has mainly played and has reduced the effect that network signal disturbs.
