The recorder has reasonable structure design and clear displaying effect.
Description
Technical field
The utility model relates to a kind of security protection video recording equipment, and particularly a kind of 1080P, resolution of providing reaches the DVR that 1920 * 1080 high definitions show output.
Background technology
Though traditional DVR also provides VGA to show output, but connect the high definition flat-panel monitor, the output picture have a display resolution more than 1280 * 1024, but its picture true resolution has only 720 * 576 sizes.When the multi-channel video image shows simultaneously, during as 9 picture segmentation, every road video can only reach 240 * 192 resolution, and when 16 road videos showed simultaneously at individual monitor, the display resolution of its each road video can only reach the display effect of QCIF (resolution 176 * 144).Trace it to its cause because technological deficiency causes, because show in the processing module at traditional DVR, picture segmentation preview chip and VGA display chip are 2 independently chips, and picture segmentation preview chip can not provide the output of digital high-definition video, because the vision signal of the output of picture segmentation preview chip has only SD form (resolution 720 * 576) size, even if therefore some VGA chip itself has high definition input interface and video processing and amplifying function, also can't really promote the true resolution of image content.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned shortcoming in the prior art, and a kind of reasonable in design is provided, and can provide 1080P, resolution to reach 1920 * 1080 the DVR that high definition shows output function that has.
The technical scheme in the invention for solving the above technical problem is: a kind of DVR with high definition demonstration output function, comprise video camera, the video decode module, picture segmentation and display module, video display apparatus, compression of digital video/decompression module, the central dispatching module, network service module, the hard disk management module, alarm control module, cloud mirror control module and human-computer interaction module, video camera is connected with the video decode module, the video decode module is connected with picture segmentation and display module again, picture segmentation and display module again with video display apparatus, compression of digital video/decompression module connects, compression of digital video/decompression module is connected with the central dispatching module again, the central dispatching module again with network service module, the hard disk management module, alarm control module, cloud mirror control module, human-computer interaction module connects, and it is characterized in that: described picture segmentation and display module are provided with high definition picture process chip.
High definition picture process chip described in the utility model is one to have the chip of 16 passages.
High definition picture process chip model described in the utility model is TW2880.
The utility model compared with prior art has the following advantages and effect: 1, reasonable in design; 2, the high definition picture process chip of She Zhiing has the function of picture segmentation preview chip and VGA display chip simultaneously, promptly only a high definition picture process chip need be set, need not to be provided with simultaneously again picture segmentation preview chip and VGA display chip, both save cost, can accelerate the research and development time of product again; When 3,4 pictures show, every road video can reach the SD display effect, when 9 pictures show, every road video can reach 640 * 480 resolution, when 16 road pictures show simultaneously, also can reach 480 * 270 display effect, and the ability that can provide more than ever before picture to show simultaneously, as 20 pictures.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Embodiment
Referring to Fig. 1, the utility model comprises video camera 1, video decode module 2, picture segmentation and display module 3, video display apparatus 4, compression of digital video/decompression module 5, central dispatching module 6, network service module 7, hard disk management module 8, alarm control module 9, cloud mirror control module 10 and human-computer interaction module 11, video camera 1 is connected with video decode module 2, video decode module 2 is connected with picture segmentation and display module 3 again, picture segmentation and display module 3 again with video display apparatus 4, compression of digital video/decompression module 5 connects, compression of digital video/decompression module 5 is connected with central dispatching module 6 again, central dispatching module 6 again with network service module 7, hard disk management module 8, alarm control module 9, cloud mirror control module 10, human-computer interaction module 11 connects.Video camera 1 can be provided with 16 at most.
On picture segmentation and display module 3, be embedded with high definition picture process chip 12, high definition picture process chip 12 is one to have the chip of 16 passages, its model is TW2880, this chip internal is integrated picture splicing, mixing, picture convergent-divergent, go interlacing, OSD stack, digital-to-analogue conversion, functions such as high definition output.High definition picture process chip 12 is supported the clear digital video input of 20 road signs, 1080P high definition simulation output, and embedded high-performance D/A and video coding can directly be exported HDMI signal and analog rgb signal.
Demonstration specification of the present utility model is as follows:
1) can show 20 pictures with screen at most;
2) can support multiple menu co-screen display modes such as 1,2,4,8,9,13,16,20, and the picture-in-picture display mode;
3) show output interface support VGA and HDMI;
4) output picture maximum can reach 1920 * 1080;
5) support true color graphic OSD interface.
Decode through video decode module 2 from the analog video signal of video camera 1 input, convert YCbCr format digital video signal S1 to, and output to picture segmentation and display module 3 by the BT656 bus.Signal S1 process picture segmentation and display module 3 inner picture splicings or picture-in-picture, image blend, image zoom, processing such as noise filtering, menu OSD stack, can show output with 1/2/4/8/9/13/16/20 menu co-screen, the HDMI or the analog rgb port that carry by high definition picture process chip 12 directly output to video display apparatus 4.Signal S1 outputs to compression of digital video/decompression module 5 by the BT656 bus after also doing video scaling, noise filtering, OSD stack by picture segmentation and display module 3 simultaneously, H.264 encode, significantly to reduce video storage space and Network Transmission bandwidth.Video data after the compression can be stored in the hard disk management module 8, perhaps is transferred to client for remotely inspecting or storage by network service module 7.
The video file that is stored in the hard disk management module 8 also can read out when needed, carry out H.264 decoding processing through compression of digital video/decompression module 5, generate the video flowing S2 of YCbCr form, output to picture segmentation and display module 3 by the BT656 bus.Video flowing S2 can show separately, also can mix with digital video signal S1, is presented at same screen.
In addition, need to prove, allly conceive equivalence or the simple change that described structure, feature and principle are done, all should be included in the protection range of the utility model patent according to the utility model patent.
