Description
Technical field
The present invention relates to a kind of video monitoring technology, be specifically related to a kind of wide-band digital video monitoring network system and method for supervising thereof based on broadband network and pure software realization.
Background technology
Along with Development of Multimedia Technology, fields such as video surveillance network is used in safety work more and more, keeps a lookout of public security, static monitoring, and bring into play the big effect of focusing on.The core of video surveillance network is the video monitoring matrix.
The video monitoring matrix is that analog video data is shown on the screen of monitor terminal by this network and video splitting equipment/method, and provide to each control point and switching capability.Its requirement can show a plurality of pictures on a screen, and each picture is controlled respectively, requires this network that the ability of processing and transferring large number of data is arranged.
Traditional video monitoring matrix is to use analog machine to realize.The analog video data that comes from the control point collection directly enters the video matrix network, controls the video of not going the same way by the switching of looking the branch instrument.In other words, traditional system all is an analogue data from collecting what be shown to control transmission, and what therefore transmit in the video matrix network promptly is the original video data that does not deal with.
There is very big defective in such monitoring network system:
At first, existing analog video data network system based on hardware to set up cost bigger;
Secondly, after in a single day this kind network is built and is finished, all equipment is just all fixing, have no idea again system to be disposed dynamically and adjusts, its employed monitor terminal also can only be the unintelligent terminal of fixed-site, it can only can not be adjusted on screen video by computer receiving and displaying video stream;
Moreover, the fabric protocol that each network service provider provides in the prior art is incompatible, cause the maintenance and the upgrading of system all very inconvenient, the upgrading of system not only can have influence on original monitor terminal, also needs extra hardware cost expense in the overlapping development of control section.
In addition, popularizing of the significant broadband network of advantage has been trend of the times, yet the such analog video network and the IP network in broadband are incompatible in the conventional art, therefore if finish the realization and the combination of these two heterogeneous networks functions, need the networking of doing to repeat.
The objective of the invention is to set up a video surveillance network system of having eliminated above shortcoming, this system utilizes video technique with the analogue data digitlization, and transmit by broadband IP network, use various data transmission technologies and video processing technique, in realization and prior art, in the on all four function of analog video matrix, the video matrix extension of network is arrived whole broadband network.And the open video matrix monitoring protocol of design is beneficial to and other system compatible.
Summary of the invention
The technical solution used in the present invention is as follows:
This system comprises a broadband network, a monitoring server, one or more monitoring host computers and one or more monitor terminal.The video stream format that each monitoring host computer all is used for the video capture device initialization and determines to provide, it is registered to carry out shaking hands of monitor video form and data Quality to monitoring server by accessing to wide band network.After the monitoring server login, described monitoring server provides the control point that can visit catalogue according to each monitor terminal user's authority to each monitor terminal by broadband network.When the user selected certain road monitor video by a monitor terminal, monitoring server was notified corresponding monitoring host computer to send this road video and is flow to described monitor terminal.
Video acquisition and MPEG-4 encoding software are installed on monitoring host computer, video are installed on monitor terminal are shown and the MPEG-4 decoding software.
According to the performance of network and the requirement of monitoring performance, become the data flow of phase code rate behind the video data process MPEG-4 technology for encoding.The data of each control point are transferred to broadband IP network after being pooled to monitoring host computer.The frame sequence that the MPEG-4 algorithm provides a key frame (I frame) and changing frame (P frame) to form for the variation between Video stream information content frame and the frame.By initiatively giving up the data of P frame, we can set up the multichannel divided frame at monitor terminal, and some of big picture videos are provided simultaneously.
Each monitoring host computer carries out one or more video acquisition according to the quantity that video frequency collection card is installed, and the data of collection are encapsulated into through Real-time Transport Protocol after by the MPEG-4 coding can be at the live video stream of Network Transmission.Monitoring host computer can adopt modes such as broadcasting, multicast and clean culture to send data flow.Every monitoring host computer is at first being registered on monitoring server after the operation.
Monitoring server exists as the LIST SERVER and the control point Yellow Page of whole system, plays regulating and controlling effect in system.If the monitoring matrixing network provides service to whole broadband network, monitoring server also will be as control centre so, and the video data stream of transmitting in the Control Network is no more than the specified network bandwidth.
The utilization of broadband network and Digital Transmission makes monitor terminal can be positioned at any position on the broadband network neatly, receives the several video flowing.These video flowings can be the combinations of the video flowing that sends on one or more different monitoring main frames.Monitor terminal receives multi-path video stream, goes up at computer (or digital projection equipment) to show the multichannel divided frame.
The monitor terminal computer is connected to broadband network, after being connected with monitoring server and determining the position of monitoring host computer, and the direct video data of receiving group or clean culture.Terminal can receive the video flowing of multichannel (M), and it can be the combination of the video data stream of one or more monitoring host computers.The terminal computer screen provides the divided frame (QCIF) of multichannel (M) to show, simultaneously wherein part picture (N) can full frame screen in cut apart demonstration, perhaps 1 road picture can be enlarged into full screen and shows.
Terminal computer when the little picture of QCIF shows, initiatively abandons the P frame in order to save the computing capability of carrying out multipath decoding, only carries out per two seconds or the I frame demonstration of per second 1 frame.The I frame of the QCIF picture of multichannel (M) is combined in the same decoder and calculates, and therefore a terminal reality only needs N+1 decoder (decoding of QCIF+N road, M road full frame) or 1 decoder (full screen decoding) to move simultaneously.
The agreement of video monitoring matrix adopts the descriptive agreement of the opening of similar HTML.The control of control point and the form that switches with DTD are transmitted, and during when system upgrade or with the other system interconnection, incompatible instruction can directly be ignored.
This digital video monitoring network matrix provided by the present invention, the number of videos of transmitting in its video quality and the matrix changes with network performance, if it is too much that other application in the broadband network occupy bandwidth, just may influence the video quality of video matrix output, cause packet loss or visual mosaic; When same monitor terminal carries out multichannel video decoding and demonstration, be subjected to the influence of different terminals computing power, different monitor video quality can occur.But in contrast to existing video surveillance network system, its advantage is conspicuous.
Contrast existing video surveillance network system, the invention has the advantages that:
Adopt the IP network video matrix of numeral can set up monitor network flexibly, monitor terminal can be distributed in broadband network Anywhere, the attributes such as bandwidth, size and frame per second of the regulation and control video flowing that monitoring server can be intelligent.
Descriptive matrix control protocol can be very fast and the other system compatibility, and the upgrading of system can not have influence on original monitor terminal yet.Avoid of the overlapping development of the incompatible supervisory control system that causes of existing each producer of fabric protocol at control section.
Adopt the digital video monitoring network of pure software mainly to rely on computer CPU resource, from existing inner IP network basis, just can set up, cost is main analogue system well below existing hardware also, and the maintenance of system and upgrading are all very easy, do not need extra hardware cost expense.
