Description
Technical field
The present invention relates to radio transmission technical field, be meant a kind of wireless data transmission device that is used for display device and method especially and based on a kind of display device of described wireless data transmission device.
Background technology
Along with the develop rapidly of wireless communication technology, people improve constantly the requirement of wireless communication system, and wish that high transfer rate, low-power consumption, low cost, the wireless communication technology that anti-interference is good are applied.Under such market expectation, super broad band radio communication (UWB, Ultra Wide Band) technology just progressively becomes the important communication technology of short-distance wireless communication.In the technology application facet, progressively in wireless portable digital camera, DVD recorder, Digital Television, wireless storage, aspects such as radio display begin to use.In addition, the development of computing machine is also developing into the alternative traditional wired connection mode of wireless connections gradually.Wherein the difficulty maximum is exactly the wireless penetration of display device.Existing scheme by wireless mode connection display device mainly contains following two kinds:
1, software implement scheme: on the PC main frame, insert the UWB network interface card, driving is installed.Additional wireless display application software is mainly finished and is grabbed screen, the compression of view data, packing, operations such as wireless transmission.
The deficiency of this scheme is mainly reflected in: a) the main frame start-up phase does not have display frame, because the UWB network interface card leans on software-driven work, the user can't carry out setting operations such as BIOS like this.B) for containing hardware-accelerated video card main frame at present, quicken to handle picture at some 3D, main frame is grabbed screen software can't realize grabbing the screen processing.C) wireless display application software must move always, constantly grabs screen, and operations such as transmission have taken system resource greatly, have reduced the host machine integral performance.
2, hardware implementations: increase a UWB annex platform in the output of main frame video card, this annex platform comprises a hardware platform, UWB network interface card and power supply, have or/no operating system, power on like this and can gather the view data of video card output, directly compress, pack, radio to the display device end of far-end.
Although this scheme can effectively solve the weak point of pure software implementation, also there are some defectives: outside main frame, increase annex platform and the external power source of UWB, use very inconvenient.Adopt the attachment design of stand-alone computer, make UWB annex platform only can realize the transfer function of wireless image data, and can not realize the various file transfer except that view data, limited the technology of UWB greatly and used.Herein, the data that will be used for screen display are called view data, and all the other all data are called non-picture data, and are as follows.
In the prior art,, a wireless network card that is used to transmit data must be set separately more then, could realize like this if not only need wireless demonstration but also need the various files of wireless transmission except that image.
As seen, video card of the prior art, network interface card is work separately, utilizing UWB technical, usually adopt on the hardware wireless penetration of video card part is realized wireless Presentation Function, perhaps the function of network interface card part wireless penetration realization wirelessly transmitting data file, but no matter which kind of implementation fails to make full use of the bandwidth of UWB, and it is considerable overlapping to have caused hardware to have, and has caused the resource serious waste.Have, if adopt the distinct wireless transmission scheme of two covers, how two antennas are avoided disturbing also is a problem again.

The above main frame includes but not limited to computing machine.
Above wireless data transmission device both can adopt computer socket design, also can directly design on the main frame mainboard, perhaps directly in the main frame outside annex as main frame all can.And, the power supply that all can directly use a computer, very easy to use.
The following describes the method that realizes wireless data transmission.
Fig. 5 is a schematic flow sheet of using realization wireless data transmission of the present invention.
Enter first pattern behind S1, the wireless data transmission device power-up initializing.
S2, wireless data transmission device are gathered the view data of main frame video card output, this view data is transmitted processing, after coding, compression and packing processing, give display device by antenna transmission, and, according to whether receiving from the transmitting-receiving non-picture data request of main frame to judge whether needs receive or send non-picture data to main frame, if, then carry out S3, otherwise repeat S2.
The control of S3, wireless data transmission device self enters second pattern, and configuration result is notified to the main frame of the request of initiation, and the main frame of initiating request in order to notice can begin non-picture data transmitting-receiving operation.
S4, wireless data transmission device transmit non-picture data between described main frame and another main frame, and/or give wireless display apparatus with the view data of described main frame by antenna transmission.That is to say that wireless data transmission device sends signal carrying out returning display device when non-picture data transmits, thus not only realized non-picture data alternately but also realize wireless demonstration, can certainly only mutual non-picture data and transmitted image data not.
The process that transmits non-picture data between described main frame and another main frame is: give another main frame from the non-picture data that described main frame receives by antenna transmission, maybe will send described main frame to by the non-picture data from another main frame that antenna receives.
Whether S5, wireless data transmission device judge from the transmitting-receiving non-picture data request of withdrawing from of main frame whether non-picture data receives or send and finish according to receiving, if then carry out S6; Otherwise repeat S4.
S6, wireless data transmission device configuration self enter first pattern, and configuration result are notified to the main frame that initiation is asked, execution in step S2 then.
Under second pattern, the data that will receive from described main frame when wireless data transmission device, comprise non-picture data and view data, when giving another main frame and display device by antenna transmission, be data packet addressed, send for respectively another main frame and display device according to the data to be sent that receive.On specific implementation, can be time division multiplex, also can be frequency division multiplexing, specifically adopting which kind of mode is to determine according to different wireless transport modules.
Introduce a kind of display device below based on described wireless data transmission device.
