As shown in Figure 1; Described wireless transmission module also comprises usb 1 13, SD interface 112, CF interface 105; The output of above-mentioned interface links to each other with the input of wireless sending module 101 through audio frequency and video processing module 104, and USB interface can external USB flash disk memory, MP3 memory or PC.
After usb 1 13, CF interface 105, SD interface 112 are gone in USB flash disk memory or MP3 memory, CF card, SD clamping; Audio frequency and video processing module 104 notice transmitting terminal processors 102; Transmitting terminal processor 102 is accomplished the identification of peripheral hardware automatically; And data are sent into audio frequency and video processing module 104 treatment conversion become wireless sending module 101 desired number formats; And send into wireless sending module 101, and wireless sending module 101 sends to the Data Receiving module with projection signal, and the Data Receiving module is sent on the projecting apparatus after with data processing and is shown.
Usb 1 13 can also connect PC; Needing install software that the PC screen is shown data on the PC handles; This software timing grasps the PC screen and shows data; Handle and send to audio frequency and video processing module 104 through usb 1 13, audio frequency and video processing module 104 notice transmitting terminal processors 102, transmitting terminal processor 102 are handled data according to projective parameter; And send into 104 pairs of projection signals of audio frequency and video processing module and carry out the vision signal processing, again projection signal is sent out through wireless sending module 101.
As shown in Figure 2; Described Data Receiving module also comprises WIFI adapter 209; WIFI adapter 209 and 207 two-way connections of receiving terminal processor; Another output of WIFI adapter 209 links to each other with VGA interface b203 with HDMI interface b206 through signal conversion module 205, and another input of signal conversion module 205 links to each other with receiving terminal processor 207.
After will needing projected data to send out on the PC through the software format transformation and through the WIFI WLAN; The automatic configuration ID of WIFI adapter in the Data Receiving module; Receive and to send into receiving terminal processor 207 behind the signal and carry out data processing, receiving terminal processor 207 is sent the data for projection after the analyzing and processing into signal conversion module 205 and is converted to behind VGA or the HDMI signal to send in projecting apparatus or the HDTV through HDMI interface b206 and VGA interface b203 and show.
Described power transfer module 208 also links to each other with power output interface 212, and power output interface 212 external projecting apparatus or HDTVs are for it provides power supply.
This power mode in the Data Receiving module makes general projectors directly from device, to obtain power supply, need not extra power-supply wiring and installs.
Like Fig. 1, shown in Figure 2, said data are sent module and are also comprised mouse and the keyboard 103 that links to each other with transmitting terminal processor 102, and said Data Receiving module also comprises the button 204 that links to each other with receiving terminal processor 207.
When the interface in the data transmission module had signal to insert simultaneously respectively, the user can send the mouse and the keyboard 103 that carry in the module through data and select which signal to come Projection Display.
The Data Receiving module can be selected different output interfaces through button 204 under the WHDI transmission channel: HDMI interface b206 and VGA interface b203.When the data reception group selection when HDMI interface b206 exports, wireless receiving module 201 is sent the digital audio-video signal that receives into behind HDMI sending module 211 decoded datas HDMI interface of sending into projecting apparatus or HDTV through HDMI interface b206 and is shown.When the data reception group selection when VGA interface b203 exports; Wireless receiving module 201 is sent the digital audio-video signal that receives into video AD C module b202, and data for projection conversion back is shown through the VGA interface that VGA interface b203 sends into projecting apparatus or HDTV.
Described Data Receiving module can be set to a plurality of, forms data and sends the pattern of module to the work of a plurality of reception module.
When a signal source need be under many projecting apparatus during Projection Display; Each projecting apparatus need connect data and receive module; Data are received module address number is set; Make data transmission module and data designated receive the mode of operation that module forms one-to-many, i.e. signal source Projection Display under some projecting apparatus of appointment.
Under the WIFI channelling mode; When need realizing a PC, the user can control when showing different projecting apparatus; Need be at PC end installation and control software, through the projecting apparatus that Control Software selects appropriate address to number, the processor 207 of receiving terminal can analyze corresponding address information automatically; Again information is sent into projecting apparatus and show, so just can realize the projection mode of one-to-many.
Described data transmission module can be set to a plurality of, forms a plurality of data and sends the pattern of modules to the work of a plurality of Data Receiving module.
When a plurality of signal sources are shared a projecting apparatus; External one has the data of appropriate address numbering to send module on each signal source machine; Can select the data for projection on the signal source machine of appropriate address numbering on projecting apparatus, to show at Data Receiving module end through button 204, so just realize the effect of many-one demonstration.
The existing projecting apparatus that possesses radio function is based on wireless local area network technology; Because the display message data volume is big; Existing network bandwidth transfer rate (bandwidth of 802.11b has only 11Mbps) is low; Can't guarantee that display image can smoothly show in real time, and poorer for dynamic content display effects such as animation, Flash.
WHDI sends, receiver module adopts the OFDM technology, can transmission bandwidth be the incompressible harmless audio-video signal of 3gbps, and signal quality can reach 1080p, and transmission range reaches 30 meters.Guaranteed the level and smooth clear demonstration of image of the present invention, made dynamic display effect better.
