Description
Technical field
The present invention relates to take turns cutting apparatus, system and method, more particularly, the present invention relates to a kind of wheel cutting apparatus, comprise that this takes turns the wheel cutting system based on multicast of cutting apparatus, and be applied to the wheel blanking method that this takes turns cutting system based on multicast based on multicast.
Background technology
Along with popularizing day by day and the development of digital technology of broadband network technology, after the video monitoring technology is gone through simulation monitoring, digital supervision, to the large scale network monitoring development: the video data after the encoding compression processing is sent to network by local area network (LAN), wide area network, wireless network or alternate manner can extends to Anywhere, the user is as long as just can carry out real-time monitoring and management by computer.The building network video monitoring system mainly contains following two kinds of patterns at present: 1, adopt the decoding of hardware encoding and hardware to make up full digital monitoring system, its front end adopts code-shaped product to transfer analog signal to digital signal and is sent to Surveillance center by network after the encoding compression again, and its Surveillance center utilizes host computer executive logging, management control on the one hand, shows after by the codec type product digital signal being reduced into analog signal on the other hand; 2, adopt hardware encoding and software decode to make up full digital monitoring system, show after utilizing the form of software decode that digital signal is reduced into analog signal.
Realize the network mid point since the efficient data transmission of multiple spot from multicasting technology, become the development main flow of present large scale network monitoring based on the real-time monitoring system of multicast.So-called multicast adopts the notion of multicast group address exactly, the user who needs data is enrolled user's group, and utilize some senior procotols to guarantee most economical land productivity dedicated bandwidth, and data are organized the user who passes to real needs by the user.Multicast group address is some special IP addresses, does not represent concrete main frame, but represents the set of a series of systems.When transmitting data to a plurality of recipient by multicast, main frame only need send a copy of data, and only there be once (as shown in Figure 1) in each bag on a given network.And when transmitting data to a plurality of recipient by clean culture, main frame must send a plurality of copies of data in turn, once sends a copy, and network is forwarded to them each recipient (as shown in Figure 2) respectively.Because in monitoring in real time; regular meeting has a plurality of clients to monitor same monitor terminal simultaneously; monitor terminal only need send one tunnel video data stream when adopting multicasting technology, and switch duplicates many parts as required and gives different clients, can alleviate network load effectively, reduce network delay.
The round cut of monitoring image is a critical function of video monitoring system, is used widely.The user to selecting one group of predetermined monitored object, is periodically switched the video image of predetermined monitored object by client, and shows by video wall or computer screen.
Traditional supervisory control system generally adopts matrix device to carry out round cut, its implementation has based on manual switchover, also there is employing to automatically switch, but the switching of adopting multipoint control unit MCU (MultipointControl Unit) to come gating matrix equipment and image segmentating device mostly, to realize the round cut of monitor video, its structure as shown in Figure 3.
Mainly there is following problem in video round cut for utilizing matrix device to realize: the interruption, shake, Ma Saike, burr and the smear phenomenon that 1, cause monitoring image easily; Network blockage appears in the time of 2, may causing the same monitor terminal of multi-user access; 3, client is general maximum can only carry out 16 tunnel video round cut; 4, the cost of whole monitoring system can improve because of introducing matrix device.
Summary of the invention
Developing state according to above-mentioned supervisory control system, and at taking turns the problem that incision technology exists in the existing supervisory control system, the purpose of this invention is to provide a kind of wheel cutting apparatus based on multicast, a kind ofly comprise that this takes turns the wheel cutting system based on multicast of cutting apparatus, and a kind ofly be applied to the wheel blanking method that this takes turns cutting system based on multicast.
