Fig. 2 is the schematic flow sheet setting up media channel in the embodiment of the present invention in advance, comprising:
Step 21: monitoring terminal sends to Control Server and starts round cut plan request.
Wherein, monitor terminal and can also be called client unit (ClientUnit, CU). In order to realize the static round broadcasting of many group monitoring, first monitoring terminal needs to start round cut plan, and such as, monitoring terminal sends startup round cut plan request to Control Server and then starts round cut plan. After starting round cut plan, Control Server can according to round cut plan, and grouping carries out video switching until round cut plan stops.
Round cut plan can comprise the information of the front monitoring front-end unit that often group comprises, and switching interval, front monitoring front-end unit can comprise camera here. Such as, round cut plan has two groups of round cut groups, first group of round cut group comprises camera A and camera B, 2nd group of round cut group comprises camera C and camera D, switching interval is T, here round cut plan is: first monitoring terminal plays the video gathered when camera A and camera B monitors, and plays the video gathered when camera C and camera D monitors after T time; Afterwards, then through T time, then again play the video gathered when camera A and camera B monitors, so circulate.
Above-mentioned startup round cut plan request can be that monitoring terminal sends at setting-up time point, and such as, setting-up time is point in the morning 9, then monitor terminal and send this startup round cut plan request at 9 in the morning; Can also being that monitoring terminal sends in setting situation, such as, namely monitoring terminal sends this startup round cut plan request upon actuation.
Step 22: the front monitoring front-end unit list in the round cut group of Control Server inquiry round cut plan.
Wherein, Control Server can pre-configured round cut group, each round cut group preserves corresponding front monitoring front-end unit list, each front monitoring front-end unit list preserves the information of corresponding front monitoring front-end unit. Such as, above-mentioned round cut plan comprises 2 round cut groups, first round cut group comprises the first front monitoring front-end unit list, this the first front monitoring front-end unit list comprises the information of camera A and the information of camera B, 2nd round cut group comprises the 2nd front monitoring front-end unit list, and the 2nd front monitoring front-end unit list comprises the information of camera C and the information of camera D.The information of camera can comprise: the mark of camera, title, numbering etc.
Step 23: Control Server, according to front monitoring front-end unit list, sends startup command to media management server.
Wherein, this startup command is carried information and the monitoring end message of the front monitoring front-end unit in front monitoring front-end unit list, is used to indicate media management server and sets up media connection with corresponding front monitoring front-end unit.
Such as, in current round cut plan, there are two groups of round cut groups, often organize round cut group and comprise two front monitoring front-end unit respectively. Namely the first front monitoring front-end unit list that this first round cut group is corresponding comprises the information of camera A and the information of camera B, 2nd front monitoring front-end unit list corresponding to the 2nd round cut group comprises the information of camera C and the information of camera D, then Control Server sends 4 startup command to media management server, a startup command is carried the information of camera A, another startup command is carried the information of camera B; Startup command is also once carried the information of camera C, and startup command is also once carried the information of camera D.
It should be understood that above-mentioned Control Server can also only send a startup command to media management server, this startup command is carried the information of all front monitoring front-end unit in front monitoring front-end unit list, namely carries the information of the information of camera A, the information of camera B, the information of camera C and camera D.
It should be understood that above-mentioned Control Server can also send startup command twice according to round cut plan component, at the beginning, the startup command that first time sends contains the first front monitoring front-end unit list corresponding to the first round cut group and comprises the information of camera A and the information of camera B, then, the startup command that second time sends contains the 2nd front monitoring front-end unit list corresponding to the 2nd round cut group and comprises the information of camera C and the information of camera D.
Above-mentioned monitoring end message can comprise the mark of monitoring terminal, the information such as the IP address of terminal
Above-mentioned startup command can be specially and start entity browse request.
Step 24: media management server sends request response to Control Server.
Step 25: Control Server sends to monitoring terminal and starts round cut plan response.
Step 26: after media management server receives startup command, according to the instruction of startup command, sets up one by one and is connected with the media of each front monitoring front-end unit. It may be that media management server one by one to each front monitoring front-end unit send set up request, front monitoring front-end unit receive set up request after and media management server connect. This front monitoring front-end unit can also be called peripheral unit (PeripheralUnit, PU)
Such as, after media management server receives the startup command of the information carrying camera A, then send, to camera A, the request of foundation, to set up and the connection of camera A. After media management server receives the startup command of the information carrying camera B, then send, to camera B, the request of foundation, to set up and the connection of camera B.
Set up after media are connected at media management server and each the front monitoring front-end unit in round cut plan, the real time video data monitored can be transferred to media management server by each the front monitoring front-end unit in round cut plan, so that media management server is selected the real time video data of the front monitoring front-end unit taking turns to plan is transferred to monitoring terminal according to round cut plan.
Step 27: media management server, according to the monitoring end message in startup command, is set up media with monitoring terminal and is connected.
Such as, media management server sends, to monitoring terminal, the request of foundation, and monitoring terminal is set up media with media management server after receiving the request of foundation and is connected.
It should be understood that the ordinal relation restriction that above-mentioned steps 26 is not clear and definite with step 27. Certainly, in order to improve reliability and efficiency, it is possible to first connect with front monitoring front-end unit, connect with monitoring terminal again after connecting with front monitoring front-end unit.
The present embodiment is connected with monitoring terminal by media management server and front monitoring front-end unit, it is possible to when round cut occurs, shorten and even avoid media stream to interrupt the time. In addition, during owing to connecting in handoff procedure, front monitoring front-end element number after handover is more, and under switching time shorter scene, it is necessary to concurrent in short-term set up more connection, system can be caused very big burden, reduce system performance, and the present embodiment is by setting up above-mentioned connection when starting round cut plan, instead of handoff procedure connects, burden system caused can be avoided, it is to increase system performance. In addition, after above-mentioned connection establishment, remain when round cut plan performs, avoid the action repeatedly creating dismounting media connection caused owing to frequently switching, it is to increase handling property.
After connecting according to the flow process shown in Fig. 2, it is possible to adopt following embodiment to perform round cut flow process.
Fig. 3 is the method flow schematic diagram of second embodiment of the invention, and Fig. 4 is system architecture schematic diagram corresponding to second embodiment of the invention, and see Fig. 4, media management server connects with each front monitoring front-end unit and monitoring terminal.
See Fig. 3, the present embodiment comprises:
Step 31: according to round cut plan, Control Server sends switching order to media management server.
Wherein, carrying switching interval in round cut plan, after arriving switching interval, Control Server will send switching order to media management server. Such as, after starting round cut plan, first starting the first round cut group, after arriving switching interval after the first round cut group starts, then Control Server sends switching order to media management server, to be switched to the 2nd round cut group from the first round cut group.
Step 32: the media channel between media management server with to be switched front monitoring front-end unit and media management server are connected by media management server with the media channel of monitoring terminal.
Owing to media management server passes through media channel, real-time receives all front monitoring front-end unit video data, in addition, media management server also passes through media channel, keep being connected in real time with monitoring terminal, therefore when according to round cut plan, when needing the monitor video data of certain front monitoring front-end unit are sent to monitoring terminal, as long as media management server selects the monitor video data receiving this front monitoring front-end unit, and the video data transmitting of this selection is delivered to monitoring terminal, namely be equivalent to media management server the media channel between media management server with to be switched front monitoring front-end unit and media management server are connected with the media channel of monitoring terminal, now media management server is equivalent to a more-control switch, can control the video data transmission of certain front monitoring front-end unit in real time to monitoring terminal according to round cut plan.
Wherein, switching order can be carried the information of to be switched front monitoring front-end unit, such as: the mark that to be switched front monitoring front-end unit can be carried in switching order, title, the information such as numbering. Assume that to be switched front monitoring front-end unit is front monitoring front-end unit-1, after then media management server receives to be switched order, determine that to be switched front monitoring front-end unit is front monitoring front-end unit-1, then by the media channel with front monitoring front-end unit-1, and media management server is connected with these two passages of media channel of monitoring terminal.After media channel connects, the data received, receiving after the data of front monitoring front-end unit-1, are sent to monitoring terminal by media management server.
Step 33: Control Server sends I frame request to be switched front monitoring front-end unit.
Wherein, Control Server can preserve round cut plan, this round cut plan can preserve the information of to be switched front monitoring front-end unit corresponding to each round cut. Such as, the information of the to be switched front monitoring front-end unit that the first round cut group is corresponding: the information of camera A and the information of camera B; The information of the to be switched front monitoring front-end unit that the 2nd round cut group is corresponding: the information of camera C and the information of camera D.
In addition, can also preserving switching interval in round cut plan, according to this switching interval, Control Server can determine current switch groups, and then determines that the front monitoring front-end unit that current switch groups comprises is above-mentioned to be switched front monitoring front-end unit. Such as, Control Server, after receiving the startup round cut plan request that monitoring terminal sends, can start round cut plan, and this round cut plan, from the first round cut group, take switching interval as the cycle, each round cut group switched successively. As, after starting round cut plan, first corresponding switch groups is the first switch groups, and corresponding to be switched front monitoring front-end unit is camera A and camera B; After the time that the first round cut group starts arrives switching interval, corresponding switch groups is the 2nd switch groups, and corresponding to be switched front monitoring front-end unit is camera C and camera D.
Moreover, above-mentioned I frame request is used to indicate to be switched front monitoring front-end unit and sends I frame.
Step 34: I frame is carried in media data to be sent to media management server by be switched front monitoring front-end unit.
Owing to front monitoring front-end unit is that the video data transmission it monitored in real time is to media management server, when front monitoring front-end unit is to media management server transmitting video data in addition, first transmit I frame, after transmission I frame, a series of P frame or B frame can be passed, and then the next I frame of transmission, and after I frame, a series of P frame or B frame can be passed, analogize with this. Therefore when switching, front monitoring front-end unit may by the content delivery of P frame or B frame to media management server, P frame or B frame are transferred to monitoring terminal by media management server, such monitoring terminal just makes the black screen of picture because not having I frame, the phenomenons such as Hua Ping, therefore when receiving I frame request, no matter to be switched front monitoring front-end unit is send I frame at this moment, or B frame or P frame, edit an I frame all at this moment, and this I frame be sent to media management server.
Step 35: the media data carrying I frame is sent to monitoring terminal by media management server.
Wherein, terminal is monitored after receiving I frame, it is possible to obtain video data according to the I frame decoding received.
It should be understood that step 32 and step 33 not ordinal relation, step 32 can first be done, can also step 33 first performing, as long as meeting when switching, the I frame data that the front monitoring front-end unit after switching sends are transferred to monitoring terminal by media management server.
The present embodiment is connected with front monitoring front-end unit and monitoring terminal respectively by media management server before the handover, can ensure that shooting first code stream does not interrupt, shorten aperture time during monitoring terminal switch, eliminate and switch the black screen caused, green screen and flower screen, it is to increase monitor staff's perceptibility; In addition, by shortening switching time, the monitoring potential safety hazard produced is eliminated in handoff procedure.
