Description of drawings
Below with reference to accompanying drawings specific embodiments of the present utility model is described in detail, in the accompanying drawings:
Fig. 1 is the system schematic that DPF passes through data forwarding device display terminal information.
Embodiment
A problem that makes DPF finish PC Presentation Function maximum is to show the transmission bandwidth problem, if compressed transmission data not, then image is too big, can't transmit, if the display device of 800*600*30Hz resolution compressed transmission data not for example, the data volume in one second is exactly 41.2Mbytes/s, and present technical standpoint is difficult to realize.But nearly all DPF all has the function of fast decoding jpeg image, and the coded hardware cost of jpeg image is also very low, and JPEG can be under the situation of very little distortion with compressing original data 10-20 doubly, and this speed is present acceptable.So as display device, use data forwarding device to address this problem with JPEG compression module for DPF.Below elaborate the structure and the course of work of DPF and data forwarding device thereof
Fig. 1 is the system schematic that DPF passes through data forwarding device display terminal information.This system comprises DPF 110, data forwarding device 120 and terminal 130.Wherein, DPF 110 comprises first wireless module 111, host chipset 112, jpeg decoder 113, display 114, memory device 115, audio-frequence player device 116, user instruction input equipment 117.Data forwarding device 120 comprises second wireless module 121, jpeg coder 122, graphics/audio getter 123, sequencing unit 124.Terminal 130 is terminal equipments such as computer or mobile phone.
Need to prove that jpeg decoder and jpeg coder are not limited to the JPEG form, also can be the codec of other form, as the JPG codec.
DPF 110 at first needs the user to open the computer Presentation Function of DPF by the information in data forwarding device 120 display terminals 130.
The operational order of user instruction input equipment 117 recording users in the DPF 110, and this operational order is sent to host chipset 112.In the example, this user instruction input equipment 117 is a touch-screen, and this user is operating as the click touch-screen.
Host chipset 112 receives the operational order from user instruction input equipment 117, and this operational order is sent to first wireless module 111.In the example, this first wireless module 111 is the WIFI wireless module.
First wireless module 111 will be sent to second wireless module 121 in the data forwarding device 120 by wireless mode from the operational order of host chipset 112.In the example, this second wireless module 121 is the WIFI wireless module.
Second wireless module 121 will be sent to sequencing unit 124 from the operational order of first wireless module 111.Sequencing unit 124 receives this operational order, and this operational order is decoded into the instruction (as mouse action) that terminal 130 can be discerned, and the instruction after will deciphering again is sent to terminal 130.In the example, sequencing unit 124 and terminal 130 are connected by USB interface.
The operational order that terminal 130 is resolved from sequencing unit 124, and carry out corresponding operating according to the particular content of this operational order, as this operational order is resolved to the audio, video data that obtains appointment in the terminal, and then the respective image voice data is sent to graphics/audio getter 123.
Graphics/audio getter 123 receives the voice data and the unpressed view data of self terminal 130, and this voice data is sent to second wireless module 121, and unpressed view data is sent to jpeg coder 122.Jpeg coder 122 should unpressed Image Data Compression become jpeg data, and this jpeg data is sent to second wireless module 121.In the example, graphics/audio getter 123 is connected by VGA interface, audio interface or USB interface with terminal 130.
Second wireless module 121 is sent to first wireless module 111 by wireless mode with voice data and jpeg data.
Host chipset 112 reads voice data and the jpeg data in first wireless module 111, and this voice data is sent to audio-frequence player device 116, and this jpeg data is sent to jpeg decoder 113.113 pairs of jpeg datas of jpeg decoder decompress, and the image after will decompressing is sent to display 114.In an example, this jpeg decoder 113 is the high speed JPEG decoding device.
Display 114 will show from the image after the decompression of jpeg decoder 113; Audio-frequence player device 116 will play back with speech form from the voice data of host chipset 112, and then finishes the function of audio, video data in DPF 110 playback terminals 130.
If what the user opened is the DPF Presentation Function, then this DPF is only finished the function of the demonstration digital photo of common DPF, and the concrete course of work is as follows:
Host chipset 112 reads the data on the memory device 115 in the DPF, and isolates wherein jpeg data and voice data, jpeg data is sent to jpeg decoder 113 again, and voice data is sent to audio-frequence player device 116.113 pairs of jpeg datas of jpeg decoder decompress, and the image after will decompressing is sent to display 114.Image after display 114 will decompress shows; Audio-frequence player device 116 plays back this voice data with speech form.Simultaneously host chipset 112 also can be by being sent to display 114 with other display message (as osd information), and then other display message that will be somebody's turn to do as osd information by display 114 show.
Obviously, under the prerequisite that does not depart from true spirit of the present utility model and scope, the utility model described here can have many variations.Therefore, the change that all it will be apparent to those skilled in the art that all should be included within the scope that these claims contain.The utility model scope required for protection is only limited by described claims.
