Embodiment

Below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail.

Embodiment one

Present embodiment describes and do not adopt MS to carry out forwarding media stream, and without the need to managed concentratedly by VM fact monitoring flow process.

In the present embodiment, on EC, correspond to the Media Stream configuration media stream message priority adjustment event of the live monitoring business between this EC and client in advance, when satisfied imposing a condition, described media stream message priority adjustment event will be triggered.In addition, on EC, be also configured for the strategy of adjustment media stream message priority in advance, so that when media stream message priority adjustment event is triggered, EC adjusts the priority of respective media stream packet according to the strategy of adjustment media stream message priority.

Media stream message priority adjustment event can comprise one of following or combination in any:

Region alarm event A, when the picture in the setting regions of video monitoring picture changes, this alarm event is triggered.Such as, when having people or thing to enter in video monitoring picture appointed area, by this alarm event of triggering A;

Interlock alarm event A, when the alarm associated with video monitoring picture is triggered, this alarm event is triggered.Such as, video monitoring picture is the monitored picture of gateway, and this monitored picture associates with the gate control system of this gateway, and when the gate control system generation alarm of this gateway, triggering links alarm event A by the video monitoring picture associated with this gate control system;

Time alarm event A, when the initial time of the time period set reaches, this alarm event is triggered.Such as, can using certain time period at night as the time period needing key monitoring, when this time period arrives, then triggered time alarm event A.

Further, also region alarm event A or interlock alarm event A can be combined with section correlation time, that is, the picture in the setting regions of video monitoring picture change and current in setting-up time section time, by toggle area alarm event A; Or, the alarm associated with video monitoring picture be triggered and current in setting-up time section time, by triggering interlock alarm event A.

When these events are triggered above, the strategy of adjustment media stream message priority can specify the priority improving respective media stream packet.Wherein, so-called respective media stream packet is the media stream message of the live monitoring business corresponding with this event, also the media stream message of the client that there is this live monitoring business relation with EC is namely sent to, as, customer end A and customer end B all establish the live monitoring business relation of receiver, video passage a with EC, then customer end A and customer end B are the client that there is this live monitoring business (i.e. the live monitoring business of receiver, video passage a).

Media stream message priority adjustment event also can comprise one of following or combination in any:

Region alarm event B, after the priority of media stream message corresponding to video monitoring picture improves because region alarm event A is triggered, picture recovery in this region is the state before region alarm event A triggers, and lasting duration exceedes setting duration, and region alarm event B is triggered;

Interlock alarm event B, after the priority of media stream message corresponding to video monitoring picture improves because interlock alarm event A is triggered, in setting duration, associated alarm no longer occurs, interlock alarm event B is triggered;

Time alarm event B, after the priority of media stream message corresponding to video monitoring picture improves because time alarm event A is triggered, when reaching the end time of the time period corresponding to time alarm event A, then alarm event B is triggered this time.

When these events are triggered above, the strategy of adjustment media stream message priority can specify the priority reducing respective media stream packet.

During concrete enforcement, may correspond to monitored picture or shooting channel setting region alarm event A and B, or be the monitored picture that is associated with other alarm or shooting channel setting interlock alarm event A and B, or be all or specify monitored picture or channel setting time alarm event A and B that make a video recording.

In addition, user also as required, can be arranged the media stream message priority adjustment event of other type, will not enumerate at this.

Media stream message priority adjustment event is or/and the configuration mode adjusting the strategy of media stream message priority can comprise:

Mode one: in officely what is the need for when wanting, being directly configured, as configured manually, or being configured on EC by configuration file manually on EC;

Mode two: in officely what is the need for when wanting, VM being configured, then by VM, media stream message priority adjustment event being issued to EC, the EC specified as being issued to;

Mode three: when client and EC set up live monitoring business relation, client by MS with the EC of the live monitoring business relation of its foundation on be configured.Such as, when customer end A and video camera A channel corresponding to encoder A set up monitoring relation, by VM, configuration information is configured on encoder A.

In addition, user also as required, can adopt other configuration mode on EC, configure media stream message priority adjustment event or/and the strategy of adjustment media stream message priority, will not enumerate at this.

Based on above-mentioned configuration, the fact monitoring flow process of what the present embodiment provided do not adopt MS carries out forwarding media stream can as shown in Figure 2, comprise:

Step 201, EC in the process of carrying out live monitoring business, the media stream message priority adjustment event that Real-Time Monitoring is arranged corresponding to the Media Stream of this live monitoring business.

Step 202, EC, when monitoring media stream message priority adjustment event and being triggered, according to the strategy of the adjustment media stream message priority of configuration on it, adjusts the priority of corresponding media stream message.

Wherein, the Media Stream being the live monitoring business corresponded between EC and client due to media stream message priority adjustment event is arranged, therefore this event is corresponding with shooting passage, also namely corresponding with video monitoring picture, therefore, by adjustment priority media stream message be the media stream message corresponding with corresponding video monitored picture or passage of making a video recording.Such as, for region alarm event A or B, corresponding media stream message refers to the media stream message corresponding to the video monitoring picture of this event monitoring; For interlock alarm event A or B, corresponding media stream message refers to other alarm association and media stream message corresponding to the video monitoring picture of this event monitoring; For time alarm event A or B, corresponding media stream message can media stream message corresponding to the video monitoring picture of this event monitoring, can be specifically the media stream message corresponding to all or part video monitoring picture that this EC sends.

Concrete, if the event be triggered is region alarm event A, corresponding shooting gap marker is a, then the priority of the media stream message of shooting passage a improves by EC; If the event be triggered is region alarm event B, corresponding shooting gap marker is a, then the priority of the media stream message of shooting passage a reduces by EC.For the media stream message priority adjustment event of other type, priority adjustment mode is similar.

Step 203, EC continues to perform live monitoring business according to the priority of the media stream message after adjustment.

Concrete, EC can according to the media stream message priority after adjustment, and the preferential high media stream message of priority that sends is to client, and to ensure the quality of the video monitoring service of client, its specific implementation can adopt existing mode, does not repeat them here.

In the step 202 of above-mentioned flow process, be triggered example with region alarm event A, EC is by improving the priority of respective media stream packet with under type:

The priority of corresponding live stream message is adjusted to high priority by default value by EC, e.g., by the DSCP value (DSCP value can represent priority-level) in the IP head of message by default 0(BE) be adjusted to 46(EF).If this message also needs to stamp VLAN TAG(virtual local area network tags) forward, then also need the 802.1P value of correspondence to be adjusted to 5 by 0, even higher.

In the step 202 of above-mentioned flow process, be triggered example with region alarm event B, EC is by reducing the priority of respective media stream packet with under type:

The priority of live stream message is regulated back default value by high priority by EC, e.g., by the DSCP value in the IP head of live stream message by 46(EF) recall to default 0(BE).Forward if this message also needs to stamp VLAN TAG, then also need have 5 to be adjusted to 0 the 802.1P value of correspondence.

Can be found out by the description of embodiment one, the adjustment event of media stream message priority is set by Media Stream corresponding on EC and carries out Real-Time Monitoring, so that EC is when monitoring corresponding event and triggering, the priority of adjustment respective media stream packet, thus achieve the automatic adjustment of media stream message priority.

Embodiment two

Present embodiment describes and do not adopt MS to carry out forwarding media stream, but flow process is monitored in the fact need being undertaken managing concentratedly by VM.

In the present embodiment, on EC, correspond to the Media Stream configuration media stream message priority adjustment event of live monitoring business in advance, when satisfied imposing a condition, described media stream message priority adjustment event will be triggered.In addition, also on VM, configuration adjusts the strategy of media stream message priority in advance, so that when media stream message priority adjustment event is triggered, VM indicates EC to adjust the priority of respective media stream packet according to the strategy of adjustment media stream message priority.Wherein, the type of media stream message priority adjustment event can with embodiment one.The configuration mode of the strategy of media stream message priority adjustment event or adjustment media stream message priority, can the specific implementation of reference example one, as, can configure manually when needed, also can configure when client and EC set up live monitoring business relation.

Based on above-mentioned configuration, the fact monitoring flow process of what the present embodiment provided do not adopt MS carries out forwarding media stream can as shown in Figure 3, comprise:

Step 301, EC in the process of carrying out live monitoring business, the media stream message priority adjustment event that Real-Time Monitoring is arranged corresponding to the Media Stream of this live monitoring business.

Step 302, information concerning events, when monitoring media stream message priority adjustment event and being triggered, is sent to VM by EC.

Concrete, information concerning events, by sending priority adjustment request or alarm information to VM, is sent to VM by EC.The information concerning events of VM is sent to comprise:

Event type, e.g., the event be triggered is region alarm event A, or region alarm event B;

The medium stream information corresponding with the event be triggered, e.g., the shooting gap marker corresponding with the event be triggered.

Step 303, VM is according to the strategy of the adjustment media stream message priority of configuration on it, and the information concerning events received, and adjudicates the adjustable strategies of the priority of corresponding media stream message.

Concrete, if the event type in information concerning events is region alarm event A, corresponding shooting gap marker is a, then the priority of the media stream message of shooting passage a improves by VM; If the event type in information concerning events is region alarm event B, corresponding shooting gap marker is a, then the priority of the media stream message of shooting passage a reduces by VM.For the media stream message priority adjustment event of other type, priority adjustment mode is similar.Its concrete adjustment mode with embodiment one, can not repeat them here.

Step 304, VM returns indication information to this EC, to indicate this EC according to the court verdict of VM to the adjustable strategies of media stream message priority, the priority of adjustment respective media stream packet.

Concrete, indication information is returned to EC by returning configuration messages to EC by VM.Described indication information can have following several possibility situation:

Situation one: indication information comprises the sign being used to indicate and improving or reduce media stream message priority, and the medium stream information of correspondence, as shooting gap marker.

Situation two: indication information comprises medium stream information (as shooting gap marker) and corresponding numerical priority value;

Situation three: indication information comprises medium stream information (as shooting gap marker) and corresponding priority incremental value (this incremental value is that timing represents raising priority, for time negative, mark reduces priority).

Step 305, EC is according to the priority of the indication information adjustment respective media stream packet received.Afterwards, EC continues to perform live monitoring business according to the priority of the media stream message after adjustment.

Concrete, corresponding to several situations of indication information in step 304, EC can adopt following several mode to adjust the priority of respective media stream packet:

Corresponding to situation one, EC according to being used to indicate the sign improving or reduce media stream message priority, the priority of adjustment respective media stream packet.As, when improving priority, by the priority of respective media stream packet from default 0(BE) be adjusted to 46(EF); When reducing priority, by the priority of respective media stream packet from 46(EF) be adjusted to 0(BE);

Corresponding to situation two, EC, the priority of respective media stream packet is adjusted to numerical value indicated in indication information;

Corresponding to the incremental value that situation three, EC is indicated in cumulative indication information on the basis of the numerical priority value of respective media stream packet.

The one of the step 302 of above-mentioned flow process substitutes implementation and is: when the event for reducing media stream message priority is triggered, as region alarm event B, associated alarm event B or time alarm event B, then EC also can send to MS and cancel alarm information, wherein carries medium stream information (as shooting gap marker).Accordingly, in step 303 ~ 304, VM cancels alarm information according to this, and instruction EC reduces the priority of respective media stream packet, and its specific implementation is with the step 302 shown in Fig. 3.

The another kind of the step 302 of above-mentioned flow process substitutes implementation and is: when the event for improving media stream message priority is triggered, as region alarm event A, associated alarm event A or time alarm event A, when corresponding trigger condition meets always, continue to send alarm information to VM, until when corresponding trigger condition does not meet, stop sending alarm information to VM.Accordingly, in step 303 ~ 304, VM is after the alarm information receiving EC transmission, after certain hour length (this time span is greater than in step 302 time interval continuing to send alarm information), again do not receive the alarm information that EC sends, then indicate EC to reduce the priority of respective media stream packet.

Can be found out by the description of embodiment two, the adjustment event of media stream message priority is set by Media Stream corresponding on EC and carries out Real-Time Monitoring, so that EC is when monitoring corresponding event and triggering, report this event to VM, enable VM indicate EC to adjust the priority of respective media stream packet, thus achieve the automatic adjustment of media stream message priority.

Embodiment three

Present embodiment describes and do not adopt MS to carry out forwarding media stream, but flow process is monitored in the fact need being undertaken managing concentratedly by VM, is: VM can also carry out more accurate message priority according to client-side information and regulate with the difference of embodiment two.

See Fig. 4 A, the MS that do not adopt provided for the embodiment of the present invention carries out the fact monitoring schematic flow sheet of forwarding media stream, and as shown in the figure, this flow process can comprise:

Step 401, EC in the process of carrying out live monitoring business, the media stream message priority adjustment event that Real-Time Monitoring is arranged corresponding to the Media Stream of this live monitoring business.

Step 402, EC, when monitoring media stream message priority adjustment event and being triggered, sends priority adjustment request or alarm information to VM, wherein carries information concerning events.

Step 403, VM is according to strategy, the information concerning events that receives of the adjustment media stream message priority of configuration on it, and the Permission Levels of relative client, the adjustable strategies of the priority sending to the corresponding media stream message of relative client is adjudicated.

Concrete, after VM receives the information concerning events that EC sent by alarm information, (this live monitoring relation list item is set up when client and EC set up live monitoring business relation to inquire about live monitoring relation list item, wherein can comprise client identification, corresponding EC mark, shooting gap marker etc., also can comprise the Permission Levels of client), inquire the client identification (namely this client also sets up the client of live monitoring business relation with this EC) corresponding to respective media stream, and inquire about the information such as the Permission Levels of this client according to this client identification.When the Permission Levels of this client meet or exceed setting threshold, and when event type shows to need to improve media stream message priority, judgement improves the priority sending to the media stream message of this client.In like manner, if event type shows to need to reduce media stream message priority, then VM can when judging the Permission Levels of this client lower than the grade set, and judgement reduces the priority sending to the media stream message of this client.Wherein, by arranging the mode of Permission Levels threshold value, the client that Permission Levels are higher or lower can be distinguished, such as, the Permission Levels of client comprise 1-5 grade, then this threshold value can be set to 3, namely, Permission Levels are the client that Permission Levels are higher higher than the client of 3, otherwise are the client that authority is lower.

Such as, customer end A and B be fact of camera chin a on program request encoder A simultaneously, but the authority of customer end A is higher than B, reach default criterion, then when the image trigger alerts of camera chin a, VM is after the warning information receiving encoder A transmission, find to only have customer end A to meet Permission Levels requirement according to monitoring relation list item, then send configuration messages to encoder A, notify that the live message sent to customer end A is heightened priority by it, and do not make change to the live message that customer end B sends.

Further, consider that the Permission Levels number of client can exceed message prior number of stages, and the network equipment is not simple the increasing progressively of priority according to message and preferentially forwards, when needing when there being the priority of multiple media stream message to regulate, VM is for the client meeting Permission Levels requirement, and by sending to, the priority of the media stream message of these clients is unified is adjusted to identical priority.Concrete, VM inquire corresponding to these Media Streams meet Permission Levels require client after, the priority of the media stream message sending to these clients is adjusted to a unified priority, such as by the DSCP value of IP head by default 0(BE) be adjusted to 46(EF).

Step 404, VM returns indication information to this EC, sends to the priority of the respective media stream packet of relative client to indicate this EC according to the court verdict adjustment of VM.

Step 405, EC sends to the priority of the respective media stream packet of relative client according to the indication information adjustment received.Afterwards, EC continues to perform live monitoring business according to the priority of the media stream message after adjustment.

Further, carry out in the monitor network of live business there is multiple client simultaneously, when the Permission Levels of multiple client are different, in order to ensure that the client of highest weight limit grade can be preferentially received live stream, VM can be utilized to carry out comprehensive optimum management to the media stream message in monitor network.

Concrete, situation about adjusting is carried out by sending to the media stream message priority meeting the client that Permission Levels require for VM in step 403, when many live stream message priorities in network are all adjusted to high priority (DSCP value changes 46 into), high-priority queue on the network equipment may be caused to occur packet loss.When client detects that the live message of reception has packet loss or packet loss to exceed setting threshold, alarm information can be sent to VM.As shown in Figure 4 B, after VM receives the packet loss alarm information of client transmission, this flow process comprises:

Step 410 ~ 411, after VM receives the packet loss alarm information of client transmission, according to the client identification wherein carried and media stream identification, inquire about live monitoring relation list item, judge that whether this client is the client that in the client side list that there is the live monitoring business relation corresponding with this Media Stream, Permission Levels are the highest, if the judgment is Yes, then step 412 is proceeded to; Otherwise, proceed to step 413.

Step 412, the priority of the live stream (namely sending to the Media Stream of this client) of the corresponding live monitoring business relation of EC raising that VM instruction is corresponding, such as by DSCP value by 46(EF) be adjusted to 48(CS6), preferentially to ensure the live monitoring business of this client.

Step 413, VM keeps current state, does not process.

In order to ensure that the client of highest weight limit grade preferentially can receive live stream, and taking into account the live stream quality of client of other Permission Levels, shown in a kind of above-mentioned Fig. 4 B, the alternative of flow process is: the priority adopting the live stream message progressively reducing other the corresponding live monitoring relation of Permission Levels client.Concrete, as shown in Figure 4 C, this flow process comprises:

Step 420 ~ 421, VM is after the packet loss alarm information receiving client transmission, according to the client identification wherein carried and media stream identification, inquire about live monitoring relation list item, corresponding video monitoring business is there is from the EC sending this Media Stream, and in the client that has been enhanced of media stream message priority, search the client that Permission Levels except described client are minimum.

Step 422, VM indicates the EC corresponding with this Media Stream to reduce the message priority of this Media Stream sending to this client, such as by DSCP value by 46(EE) be adjusted to 26(AF31), or directly return to default value 0(BE).

Further, if VM is after time delay certain hour, still receives the packet loss alarm information (step 423) that client sends, then return step 421; If after time delay certain hour, no longer receive the packet loss alarm information that highest weight limit tier customer end sends, then process ends.
