Abstract
The utility model discloses a digital TV bar with a Wifi function. The digital TV bar is characterized by comprising an application processor, and a memory, a Wifi module, a digital TV demodulator and a USB interface circuit, which are connected with the application processor. The digital TV bar integrates a digital mobile TV and a wireless internet access function, is convenient to use and easy to carry, and is low in cost compared with the cost of the digital mobile TV or a Wifi device.
Description
Technical field
The utility model relates to a kind of digital television stick, particularly relates to a kind of digital television stick with the WiFi module.
Background technology
Because the costliness of cable TV is charged, a lot of young consumer choice are bought digital television sticks, receive mobile digital TV signals, TV reception on computers through digital television stick in the market.Among the consumer, having is not again greatly having under the situation of cable broadband, perhaps connects mobile phone with WiFi through external WiFi module accesses wireless network in this section, realizes high speed Internet access through the 3G network of mobile operator.Computer self is not with the WiFi module greatly, can't connect mobile phone or wireless network through WiFi, needs to install external WiFi module and realizes the WiFi function.DTV and WiFi module all are separate modular, after the signal demodulation, all need an application processor to carry out signal decoding, can be connected with the PC end through USB interface.Independent product all needs application processor, and cost is higher relatively, and the application processor utilance is low.
Summary of the invention
The purpose of the utility model provides a kind of digital television stick with the WiFi function, has overcome digital television stick in the prior art, the separate and defect of high cost of WiFi module.
The utility model adopts following scheme to realize: a kind of digital television stick with the WiFi function is characterized in that: comprise an application processor and a memory that is connected with this application processor, a WiFi module, a digital television demodulator and a usb circuit.
In the utility model one embodiment, said application processor is a multimedia application processor, this multimedia application processor tool SDIO interface, UART interface and NandFlash interface.
In the utility model one embodiment, said memory is the two-in-one memory of Nand Flash and SDRAM.
In the utility model one embodiment, said WiFi module is connected with said application processor through Nand Flash bus, carries out transfer of data.
In the utility model one embodiment, said WiFi module is connected with application processor through the UART bus, carries out the control command transmission.
The positive progressive effect of the utility model is: the mobile digital TV rod of the utility model only adopts an application processor to integrate two kinds of functions of extensive use, and it is more convenient that the user uses, and cost is also lower.

Fig. 2 is the circuit structure theory diagram of the utility model embodiment two.
Embodiment
The preferred embodiment that provides the utility model below in conjunction with accompanying drawing is sub, to specify the technical scheme of the utility model.
The purpose of the utility model is organically to be incorporated into digital moving-tv, WiFi module in TV rod product, and this is the utility model than the place that general TV rod product has huge advantage.Its essential core is, utilizes an application processor (AP), realizes WiFi module, the shared USB interface of digital moving-tv receiving function and terminal (such as a computer) to communicate by letter.Please according to Fig. 1; Fig. 1 is the circuit structure theory diagram of an embodiment of the utility model, and the digital television stick of present embodiment is connected with computer through USB interface, and it comprises an application processor (AP); And a demodulator that is connected with this application processor, a WiFi module.Above-mentioned each element is prior art, no longer details here.This demodulator is connected with application processor through a parallel interface (SDIO).This demodulator also connects a receiver rf front-end (Tuner), and this receiver rf front-end provides i/q signal (two pairs four tunnel quadrature rf signals) to application processor.This WiFi module is connected with application processor through a NandFlash interface; Carry out transfer of data; Be connected with application processor through a UART interface (Universal Asynchronous Receiver/Transmitter, UART Universal Asynchronous Receiver Transmitter interface) simultaneously, carry out the control signal transmission.
Each major part operation principle in the digital television stick of the utility model is following:
DTV part: come after the digital television signal of satellite receives through the DTV receiver rf front-end, to pass to application processor to data through the SDIO interface then through demodulator (Demodulator) realization demodulation again; Pass to computer to video and audio signal through USB interface after the application processor reading of data, the sound card video card of computer utilization itself is realized TV functions to AV signal decoding back.
The WiFi module section: the computer expert with the WiFi module does not cross WiFi module of the utility model and user's 3G mobile WiFi module communication.User's 3G mobile obtains data through the 3G network online of mobile operator, and data are transferred to the WiFi module of digital television stick through the WiFi module of mobile phone.The data that digital television stick WiFi module is obtained are passed to computer to data through USB interface through the memory of NandFlash bus transfer to application processor after the application processor reading of data.The computer expert crosses the function of the WiFi module realization online of digital television stick.
Please with reference to Fig. 2, Fig. 2 is the circuit structure theory diagram of the utility model embodiment two, and this embodiment DTV part operation principle and embodiment one are as broad as long, no longer details here.
The WiFi module section: the WiFi module of not crossing the utility model with the computer expert of WiFi module is directly visited hotspot (AP:access point), inserts cable broadband through the visit focus.The data that digital television stick WiFi module is obtained are passed to computer to data through USB interface through the memory of NandFlash bus transfer to application processor after the application processor reading of data.The computer expert crosses the function of the WiFi module realization online of digital television stick.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
