Embodiment
In order to make the application the technical staff in the technical field more clearly understand the application, below in conjunction with accompanying drawing, by specific embodiment, technical scheme is described in detail.
The object of the invention is the method and system providing a kind of hospital ward video monitor, namely at hospital ward, the video terminal (that is: video frequency pick-up head) based on P2P stream media technology is installed, in real time or the video of timing acquiring inpatient or image, telemonitoring and long-range merit of making the rounds of the wards is realized by back-stage management platform.
First the hospital ward video monitoring system of structure of the present invention is introduced.
The structure schematic diagram of this system please refer to Fig. 1.
This hospital ward video monitoring system comprises back-stage management server; N number of P2P video server; In actual applications, N be more than or equal to 2 positive integer.Wherein, the P2P video server in N number of P2P video server and back-stage management server direct-connected; Each P2P video server comprise again number not wait P2P video terminal, wherein, a P2P video terminal and a P2P video server direct-connected.At this, mainly employ P2P technology, P2P and Peer-to-Peer, be called peer to peer connection or peer-to-peer network, refer to and exchanged by direct between different system, realize computer resource and serve a kind of application model shared.In the P2P network that back-stage management server and N number of P2P video server build, each P2P video server is the participant of equality, bears service user and ISP two roles.Now, the P2P video server in N number of P2P video server and back-stage management server direct-connected, if to back-stage management server uploading data, then need to be uploaded by a P2P video server.And certain P2P video server and under the P2P network that builds of all P2P video terminals in, a P2P video terminal and a P2P video server direct-connected.
The effect of all parts is introduced below from two aspects.First aspect is when upload video data, the effect that all parts is concrete.Second aspect is back-stage management server when pushing notice information to P2P video terminal, the effect that all parts is concrete.Notice information can be the bulletin file that back-stage management server issues, or to court verdict of certain video etc.
When upload video data:
Back-stage management server, the operation for receiving user generates and sends video access request.Specifically, M be more than or equal to 2 positive integer.Back-stage management server is mainly used to monitoring image and the video in the ward of being in hospital managing all videos, can realize video storage, remote inquiry and image early warning.The operation correspondence that back-stage management server can receive user generates and issues video access request to a P2P video server.In addition, back-stage management server is also for being combined into video data according to very first time stamp by M video segment.
One P2P video server, for receiving the video access request that back-stage management server sends, and obtains the video data of a P2P video terminal record according to video access request; And partitioning video data is become M video segment, wherein, M video segment has identical very first time stamp; And the first video segment in M video segment is sent to back-stage management server, and M-1 video segment correspondence is sent to other P2P video servers direct-connected with a P2P video server, is then transmitted to back-stage management server by other P2P video servers direct-connected with a P2P video server.For example, suppose that the video data that a P2P video server obtains has 20M, if a P2P video server directly sends this 20M video data to back-stage management server, cause circuit to block possibly, reduce efficiency of transmission.Therefore, 20M partitioning video data can be multiple video segment by a P2P video server, as being divided into 3 video segments, is respectively 5M, 10M, 5M.Then send other P2P video servers direct-connected with it respectively to, be transmitted to back-stage management server by them.In order to differentiate the feature of each video segment, very first time stamp can be added in each video segment, after back-stage management server receives the video segment that each P2P video server sends, corresponding video segment can be combined according to very first time stamp, and then synthesize complete video data.
One P2P video terminal, for receive the one P2P video server forward video access request, and according to video access acquisition request and uploaded videos data to P2P video server.
When pushing notice information:
Back-stage management server, also for notice information being divided into multiple bulletin fragment, each bulletin fragment has the second timestamp; Then multiple bulletin fragment correspondence is handed down to a P2P video server.Specifically, the second timestamp mainly in order to distinguish each bulletin fragment, preventing announcing fragment with other and obscuring.Such as, back-stage management server, by pushing the data of 10M to each P2P video server, first 10M Data Segmentation can be become 2M, the data of 3M, 5M, and this three segment data all has identical timestamp.Then it can be sent to a P2P video server by back-stage management server respectively.
One P2P video server, for receiving corresponding bulletin fragment, and be transmitted to other P2P video servers direct-connected with a P2P video server, and receive and a P2P video server direct-connected other P2P video servers transmission bulletin fragment, according to the second timestamp synthesis notice information, and notice information is handed down to a P2P video terminal.For example, a single P2P video server can receive the data that back-stage management server transmits, and also can receive the data that other direct-connected P2P video servers transmit, is then combined as notice information according to the second timestamp.
One P2P video terminal, for receiving the notice information that a P2P video server sends, and being transmitted to other P2P video terminals direct-connected with a P2P video terminal, making each P2P video terminal have notice information.
Please continue referring to Fig. 1, be described with concrete example below.
Suppose that a P2P video server is with P2P video server A, P2P video server B, P2P video server C is example.Certainly, in actual applications, P2P video server can be one or more, and the present invention does not limit at this.Wherein, P2P video server A comprises P2P video terminal a, P2P video terminal b.P2P video server B comprises P2P video terminal c, P2P video terminal d.P2P video server C comprises P2P video terminal e, P2P video terminal f.Back-stage management server 1 and P2P video server A, P2P video server B, C is direct-connected for P2P video server.
Back-stage management server 1 sends video access request to P2P video server A.P2P video server A corresponding can transfer the 20M video data that P2P video terminal a records.Then be divided into 3 video segments, be respectively 5M, 10M, 5M.And every segment data all has identical very first time stamp.5M video segment can be sent to back-stage management server 1 by P2P video server A.10M video segment is sent to P2P video server B, 10M video segment is sent to P2P video server C.Then respectively respective video segment is transmitted to back-stage management server 1 by P2P video server B, P2P video server C.
After back-stage management server 1 receives three sections of video segments, then can be combined into video data according to very first time stamp.
When back-stage management server 1 issues notice information, notice information can be divided into bulletin fragment.P2P video server A, P2P video server B, P2P video server C also can receive and forward the bulletin fragment self received, then form into separately notice information be handed down under P2P video terminal.Further, this group website of P2P video server A, P2P video server B, P2P video server C is dynamic formation, and each website dynamically can add or exit this group.Can accomplish that website as forward node forwarding data, also can receive data as leaf node like this, when deadlock or network failure appear in a website, only affect fraction website, the data transmission of whole network can not be affected.
More than the framework of hospital ward video monitoring system, below, the present invention will introduce the method for hospital ward video monitor from P2P video server, P2P video terminal, back-stage management server aspect.
