Description of drawings
Fig. 1 is that the apparatus structure of a kind of PC of cooperation wireless transmission of the utility model embodiment reaches the schematic diagram that is connected with peripheral hardware;
Fig. 2 is that the another kind of the utility model embodiment cooperates the apparatus structure of PC wireless transmission and the schematic diagram that is connected with peripheral hardware.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
The utility model mainly is that (Wireless Home Digitalinterface, WHDI) technology is used in present PC and is connected this part with peripheral hardware, uses the full Wireless transmission manner with the wireless family digital interface.The device of cooperation PC wireless transmission of the present utility model comprises: reflector that is connected with main frame and the receiver that is connected with the peripheral hardware of main frame, described receiver comprises the data-interface of the peripheral hardware that connects described main frame, described reflector comprises the data-interface that connects described main frame, described receiver and reflector include wireless transport module, wireless transport module is connected with receiver data-interface separately with reflector respectively, is used to transmit the data that described data-interface obtains.Wherein, wireless transport module is preferably the WHDI module.
As shown in Figure 1, for the apparatus structure of a kind of PC of cooperation wireless transmission of the utility model embodiment and the schematic diagram that is connected with peripheral hardware, among the figure structure of this device, the outer display and the loud speaker of being made as of main frame, both realize media play at cooperation.
Comprise the image coffret (the unified data-interface that is expressed as among the figure) that is connected with the main frame video card in the data-interface of reflector, mainly comprise VGA (Video Graphics Array), DVI (Digital Visual Interface) and HDMI (High Definition MultimediaInterface) three class interfaces, also comprise the audio transmission interfaces that is connected with the main frame sound card in the data-interface of reflector, total interface all is connected with the WHDI wireless transport module.Reflector uses the WHDI technology by wireless the Voice ﹠ Video signal to be transferred to receiver.Comprise the image coffret that is connected with described display in the data-interface of receiver, comprise VGA, DVI and HDMI three class interfaces equally.Which class interface reflector uses decide according to the video card interface, and the image coffret of receiver (being connected with display by video transmission line) is decided according to the interface of display.If video card and display interface device are inconsistent, by the conversion transmission of reflector and three style interfaces of receiver.Also comprise the audio transmission interfaces that is connected with loud speaker in the data-interface of receiver.Receiver directly is transferred to display by image coffret and audio transmission interfaces with video signal, and audio signal transmission is given loud speaker.
As shown in Figure 2, be the apparatus structure of a kind of PC of cooperation wireless transmission of the utility model embodiment and the schematic diagram that is connected with peripheral hardware, the data-interface of this device reflector also comprises: the USB interface that is connected with main frame, the data-interface of receiver also comprises the USB interface that connects with USB peripheral hardware (as USB keyboard, mouse etc.).The WHDI wireless transport module is connected with USB interface, with the wireless transmission usb data.After the peripheral hardware of USB interface is passed to receiver with usb data, receiver is given reflector by WHDI technology wireless backhaul usb data, reflector is connected with the USB interface of main frame by USB interface, and the usb data that returns is returned to host process, the action of response of host USB peripheral hardware.In like manner, main frame also can transmit order to the USB peripheral hardware.Wherein, receiver has USB HOST function, and reflector has USB DEV function.Unique " root " is arranged in the topological structure of usb bus, this root is exactly USB HOST (usb host), all USB device by USB HUB or directly and USB HOST couple together, the USB device here is exactly USB DEV, the chip USB interface that has can only be used as usb host, the chip USB interface that has can only be used as USB device and use thus that receiver must have USB HOST function, and transmitter must have USB DEV function.If the interface of any USB device just physically couples together with usb host, if but the register of usb segment is not opened and set to software, this USB interface can not replied any inquiry on the usb bus and feed back any data that this just can be understood as USB interface and has been under an embargo so, otherwise then for enabling.Because the groundwork of the wireless channel of WHDI is full HD video and a voice data of transmission, if 60HZ transmits video data, the time of the image of each frame demonstration is about 16.7ms so, because very big each two field picture of the data volume of 1080P has 15ms to be used to transmit the view data of next frame approximately, can only be between the two frames vacant time transmission of usb data, and the communication frequency of USB is than the frequency height of frame period, general interruption transmission is approximately 10ms once even faster, data conditions very likely appears losing in usb data because have no chance to send so, at this situation, the usb data that the USB HOST of receiver can be received is stored in a circular buffering, in the interval of two width of cloth images, concentrate again then usb data is sent to transmitter, can avoid the problem of usb data possibility packet loss like this.
Above execution mode only is used to illustrate the utility model; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
