Fig. 2 is the flow chart of network video monitoring method in the specific embodiment of the invention.
Embodiment
Below in conjunction with drawings and Examples technical scheme of the present invention is described further.
Fig. 1 is the structured flowchart of Network Video Surveillance device in the specific embodiment of the invention, comprise headend equipment 101, Media Stream administrative center 102 and client device 103 among the figure, Media Stream administrative center 102 comprises that Distributor 1021, storage server 1022 and time shift are provided with module 1023.Wherein,
Headend equipment 101 is used for carrying out video monitoring according to user's needs, and will monitor the real-time media stream that obtains and send to Media Stream administrative center 102.
Media Stream administrative center 102, it is one group of server zone, be used for headend equipment 101 and client device 103 mutual, the Media Stream that receiving front-end equipment 101 sends, and the request message that sends according to client device 103 is transmitted to client device 103 with Media Stream.Described Media Stream comprises real-time media stream and time shifting medium stream.
Distributor 1021 is used for Distributor and is used for distribution media stream, and when monitoring in real time, Distributor will be transmitted to client device 103 from the real-time media stream of headend equipment and be distributed to storage server 1022 simultaneously; When time shift was monitored, Distributor obtained time shifting medium stream from storage server and is transmitted to client device 103.
Storage server 1022 is used to preserve the real-time media stream of transmitting by Distributor 1021 that is produced by headend equipment 101, when receiving that request message is reviewed in signal that Distributor 1021 sends, time shifting medium stream is sent to Distributor 1021.
Time shift is provided with module 1023, is used for headend equipment is carried out the setting of time shift and time shift time span.In, the king-sized video monitoring system of headend equipment quantity wide especially at monitoring range, can require highly to real-time, frequent headend equipment takes place and carries out the setting of time shift and time shift time span in accident.
Client device 103 is used to send a request message to Distributor 1021, when monitoring in real time, sends and monitors request message in real time to Distributor 1021, and request sends real-time media stream.When accident takes place, send time shift and review request message to Distributor 1021, request sends time shifting medium stream.
Fig. 2 is the flow chart of network video monitoring method in the specific embodiment of the invention, and concrete implementation step is as follows:
In this step, headend equipment need dispose time-shifting function, if headend equipment does not dispose time-shifting function, Distributor receives real-time media stream, but refusal is transmitted to storage server with real-time media stream.
In this step, Distributor when transmitting real-time media stream and giving client device, still to storage server to this real-time media stream of distribution.
In this step, Distributor judges whether headend equipment has time-shifting function, if support, then stops to send real-time media stream, transmits time shift to storage server simultaneously and reviews request message; Otherwise, be failure to actuate.
Introduced the video monitoring process between single headend equipment and single client device and the Media Stream center in the foregoing description, but the present invention is equally applicable to the video monitoring process between a plurality of headend equipments and a plurality of client device and the Media Stream center.Comprise following situation in actual applications:
A plurality of client devices are monitored single headend equipment simultaneously; Under this situation, Distributor is after the recovery of receiving one of them client device is monitored request message in real time, check whether also have the time shifting medium stream of other client device, if then notify storage server to continue to send the time shift code stream of this headend equipment at receiving front-end equipment; Otherwise Distributor notice storage server stops to send the time shifting medium stream of this headend equipment.
Single client device is monitored a plurality of headend equipments simultaneously; Under this situation, the same with the video monitoring process of the single headend equipment of single client control in the foregoing description.
A plurality of client devices are monitored a plurality of headend equipments simultaneously; Under this situation, the same with the video monitoring process of the single headend equipment of a plurality of single client controls.
Client device is similar to the broadcast mode of the broadcast mode of time shifting medium stream and real-time media stream among the present invention, all be that Media Stream is sent to client device,, and after not needing earlier media file download, play by client device again the Media Stream broadcast of decoding by client reality.Just because of this, the method that storage server is taked directly to preserve the media stream data bag is preserved real-time media stream, so not only avoided extra process, also improved the preservation efficient of storage server, also satisfied the needs of playing time shifting medium stream simultaneously Media Stream.In addition, the present invention reduces the frequency to the memory device read-write operation by improving the internal memory service efficiency of storage server, thereby improves the single read-write efficiency of storage server effectively, and then when not influencing real-time monitoring, preserve the real-time media stream that headend equipment sends.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
