The USB device with functions of receiving digital television as well as wireless network cards of the invention combines the function of wireless network cards and the function of receiving digital television into a USB device which is easy to carry, thereby realizing the plug and play property of portable equipment in a real sense and being convenient for the use of consumers.
Description
[technical field]
This creation relates to the consumption electronic products technical field, particularly a kind of USB device that possesses Digital Television reception and wireless network card function.
[background technology]
Along with the development of digital information technology, and the GB national standard digital television begins to have the handheld device and the USB receiving system of various receiving country standard digital televisions in the progressively implementation of national standard on market, and forms certain business opportunity among the crowd gradually.Simultaneously, along with popularizing of laptop computer, and the development of wireless Internet access technology, the laptop computer that possesses wireless network card function also more and more is subjected to consumer's favor, whether yet existing wireless network card function can be single, can be one with the reception and the wireless network card function collection of Digital Television, with combining of two kinds of functions, when making it possess wireless network card function, also can doublely make the receiver of digital television signal.At present, for consumers, these two kinds of functions are all attractive, are not same products but, if think to have simultaneously this two kinds of functions, must buy wireless network card and DTV receiver, are not easy to consumer's use.So be necessary a kind of product of developmental research, so that the consumer uses.
[summary of the invention]
For addressing the above problem, main purpose of the present invention is to provide a kind of USB device that possesses Digital Television reception and wireless network card function, so that consumer's use.
For achieving the above object, technical scheme of the present invention is:
A kind of USB device that possesses Digital Television reception and wireless network card function comprises digital signal receiver module, wireless interface module, connection numeral signal receiving module and the USB controller of wireless interface module and the program module that is connected the USB controller.
Further, described digital signal receiver module includes reception antenna, connects the tuner TUNER of this reception antenna, the A/D analog to digital converter that connects tuner TUNER and the demodulator that is connected with the A/D analog to digital converter.
Further, the described wireless interface module Wifi module that includes built-in Wifi antenna and be connected with this Wifi antenna.
Compared to prior art, the USB device that this creation possesses Digital Television reception and wireless network card function is integrated in a USB device with wireless network card function and Digital Television receiving function, be easy to carry, truly realized the plug and play of portable set, be convenient to consumer's use.
[description of drawings]
Fig. 1 is a theory structure block diagram of the present invention.
Software interface diagram when Fig. 2 operates for the present invention.
[embodiment]
See also shown in Figure 1, a kind of USB device that possesses Digital Television reception and wireless network card function of the present invention comprises digital signal receiver module, wireless interface module, connection numeral signal receiving module and the USB controller of wireless interface module and the program module that is connected the USB controller.In addition, also be connected with memory, to realize the USB memory function of this device with the USB controller.
The digital signal receiver module includes reception antenna, connects the tuner TUNER of reception antenna, the A/D analog to digital converter that connects tuner TUNER and the demodulator that is connected with the A/D analog to digital converter, and described demodulator also is connected with the SDRAM memory.Wherein, the digital signal receiver module connects the USB controller by demodulator.Reception antenna receives the digital television signal that TV station sends, be sent to tuner, carry out tuning by tuner to signal, and export the A/D analog to digital converter to, send into demodulator after the analog signal conversion that the A/D analog to digital converter is exported tuner becomes digital signal, demodulator carries out demodulation with digital signal, and output TS flow to the USB controller, by the USB controller TS stream is made data packet stream and send into PC, carry out the broadcast of information by computer.Wherein, the USB controller still is the processor controls of whole device, is in charge of the work of coordinating each chip.
The Wifi module that wireless interface module includes built-in Wifi antenna and is connected with the Wifi antenna.The Wifi antenna receives wireless network signal, is handled by the Wifi module, by the control operation of USB controller, carries out interaction process with PC, realizes wireless networking capabilities.The product technology of wireless network card has been very ripe at present, and in the embodiment of this creation, described wireless network card function is exactly a built-in module that is exclusively used in the reception of WIFI signal on the PC integrated circuit board, comprises special built-in aerial and receiver module.Driver module includes that the wireless network card that is installed on the PC drives and the driving of digital television receiver, drive and after the driving of digital television receiver installs at the wireless network card of PC, software can be pointed out hardware to install and can be used, and clicks prompting figure and just interface as shown in Figure 2 can occur on PC.Wireless digital TV-set and wireless network all are in disabled status under the initial condition, need to use when receiving the wireless digital TV-set function, select startup/forbidden digit TV, finish the receiving function of Digital Television, and wireless network is in disabled status simultaneously.If select startup/forbidding wireless network card, then the digital signal receiver module can be in the standby disabled status automatically.
During application, after the driving that installs wireless network card driving and digital television receiver on the PC,, realize function corresponding by selecting startup/forbidden digit TV or startup/forbidding wireless network card.When selecting startup/forbidden digit TV, the receiving function of beginning Digital Television, wireless network is in disabled status, at this moment, the software of installing on the PC that is used for the Digital Television broadcast is opened automatically, reception antenna receives the digital television signal that TV station sends, be sent to tuner, by tuner signal is carried out tuningly, and export the A/D analog to digital converter to, the A/D analog to digital converter is sent into demodulator after the analog signal conversion of tuner output is become digital signal, demodulator carries out demodulation with digital signal, output TS flow to the USB controller, by the USB controller TS stream is made data packet stream and sends into PC, is carried out the broadcast of information by PC.If watch Digital Television for the first time, then need through the line search program, after search finishes, the program of corresponding frequency will be saved to the corresponding position of software, just not need to have searched for once more when watch next time.If select startup/forbidding wireless network card, then the digital signal receiver module can be in the standby disabled status automatically, the Wifi antenna of wireless interface module receives wireless network signal, handle by the Wifi module, control operation by the USB controller, carry out interaction process with PC, realize wireless networking capabilities.
Most preferred embodiment described above only is that the present invention is set forth and illustrates, but is not limited to disclosed any concrete form, and it is possible carrying out many modifications and variations.
