Embodiment
Below in conjunction with accompanying drawing and embodiment, describe the technical scheme of the utility model in detail.
The matrix server of the multichannel the expanded input and output of the utility model, the demonstration that is mainly used in video wall is controlled, and system interface is virtual video wall, the operation intuitive and convenient.The video matrix system that numeral coding/decoding card constitutes can receive Internet video through network adapter, also can connect outer video signal.Can carry out complicated editor, control to vision signal through digital coding/decoding card, take up an official post to mean at PC and decide the video image that display window supervises appointment, effect directly is shown on the video wall.Promptly when video image was shown in the PC system interface, the corresponding viewing area of corresponding monitor showed this video image information on video wall.The utility model can also be according to difference layout and user's use habit, the interface of configuration-system neatly of video wall.The essential information of the automatic record video image of system (such as positional information, the decoding channels index that takies and display channel index or the like), and can be used as the different configuration modes of video wall are preserved, read and recover.
Embodiment
The matrix server of the multichannel the expanded input and output of the utility model, structure is as shown in Figure 1, comprises PC and video matrix system as operation control platform.PC comprises internal memory, hard disk display adapter and the audio frequency adapter of basic configuration.The video matrix system adopts the digital coding/decoding card of plate card type structure to constitute, and digital coding/decoding cartoon is crossed the pci bus slot and is connected with said PC.Every digital coding/decoding card all has input of M road and N road to export, and some so digital coding/decoding cards can be formed the video matrix system of MXN.According to present technical merit, a PC can support the input of 64 road videos, and the output of 32 road videos, and such video matrix system can be made up of 8 digital coding/decoding cards, and every digital coding/decoding jig has 8 tunnel inputs and 4 tunnel outputs; Perhaps constitute by 16 digital coding/decoding cards with 4 tunnel inputs and 2 tunnel outputs.Can expand the matrix server of multichannel input and output can select suitable M road input and the output of N road to constitute the video matrix system according to real needs.General supervisory control system all utilizes IP network to carry out the transmission of video monitoring image, in order to receive network video stream, as the PC of operation control platform, on its pci bus slot, network adapter has been installed in this example, so that receive network video stream.
The digital coding/decoding card of this example comprises that DSP, input interface, output interface, audio frequency and video A/D converter and audio frequency and video D/A converter constitute, referring to Fig. 2.Vision signal gets into the AlD transducer through input interface, carries out the conversion of analog to digital, gets into DSP then and carries out editing and processing.On the other hand, the digital video signal of DSP output converts analog signal to through D/A converter, is sent to video wall and shows, or through internal pci bus, audio-video signal is passed through audio frequency adapter and video adapter respectively, carries out this machine and reappears.The DSP model is TMS320DM642 among Fig. 2, is the digital media processor chip of Texas Instruments, adopts the BGA548 encapsulation; Operating voltage 3.3V, core voltage 1.4V, internal work clock 600MHz (1.67ns); 4.8 hundred million instructions of computing capability per second; External bus clock 100MHz can accomplish real-time multi-channel video collection, realizes complicated audio frequency and video compression algorithm.This routine A/D converter model is SAA7144, is the product of Philips company.The function of 4 SAA7113 that SAA7144 is integrated can convert four road CVBS signals (composite video signal) to digital video signal.D/A converter adopts the SAA7121 of Philips company, can the vision signal of numeral be converted to the analog video signal of standard.The digital coding/decoding card of this example can be accomplished H.264 Code And Decode.To the signal pressure coding that contracts, the data after will encoding are then given the central processing unit of PC to DSP through pci bus by standard H.264.On the other hand; The central processing unit of PC will need the data of playback to give DSP through pci bus; Carry out decoding H.264; Decoded digital video believes that to D/A converter digital video signal is also given display adapter, and display adapter is given VGA monitor with the VGA signal that digital video signal converts standard to.
