The association mentioned in the embodiment of the present invention may specifically be establishing a binding relationship or an association relationship, that is, after associating the alarm party audio-video stream and the alarm receiving party audio-video stream recorded and obtained for the same alarm video telephone with the alarm video telephone, the alarm video telephone may be queried to find the corresponding alarm party audio-video stream and the alarm receiving party audio-video stream. If the recording resources are not bound, the recording resources stored by the storage server are scattered and unordered, and the warning situation recording associated resource list is obtained in the subsequent on-demand application, but which two recording resources are generated by one-time alarming cannot be selected, and normal warning situation on-demand cannot be carried out.

In practical application, the alarm resource codes can be set for the alarm video phones, one alarm resource code represents one alarm video phone, and the corresponding alarm resource can be searched by inputting the alarm resource code, so that the unified management of the alarm resource is facilitated.

By integrating the steps S101 to S103, the embodiment of the invention provides a recording method for audio and video streams in the alarm video telephone from the perspective of a storage server, creates two recording tasks, respectively performs split-screen recording on the audio and video of an alarm terminal and an alarm receiving terminal in the alarm video telephone, and has the characteristic of fixedly recording two paths of video and two paths of audio. Therefore, only the alarm side audio-video stream and the alarm side audio-video stream which are obtained by recording are required to be respectively assembled in a slicing mode, format packaging is carried out, coding is not required, the recording speed is higher, the performance consumption in the recording process of the storage server is greatly reduced, and the number of recordable concurrency is much higher than that of the concurrency recorded in a screen-combination mode in the prior art.

Example 2:

in order to facilitate a further understanding of the present invention for those skilled in the art, in the embodiment of the present invention, a further implementation method of embodiment 1 of the present invention is provided, and the method may specifically include the following steps:

step S101a1, receiving an alarm recording request sent by the alarm receiving terminal, wherein the alarm recording request is generated when the alarm receiving terminal is connected with an alarm video telephone dialed by the alarm terminal through a streaming media server; the warning recording request comprises information of an alarm party and information of an alarm receiving party;

in the embodiment of the invention, the streaming media server is provided with an alarm triggering interface which can be communicated with the alarm video telephone of the alarm terminal and the alarm receiving terminal. The alarm triggering interface of the streaming media server is encapsulated as a one-key alarm service in the alarm terminal. When the one-key alarm service of the alarm terminal is triggered by the user, the stream media server is called by an alarm trigger interface which can be connected with the alarm video telephone of the alarm terminal and the alarm receiving terminal. At the moment, the alarm terminal calls the alarm videophone to the alarm receiving terminal, the message of calling the alarm videophone is forwarded by the streaming media server and sent to the alarm receiving terminal, and after the alarm receiving terminal responds, the alarm videophone is established between the alarm terminal and the alarm receiving terminal. Then the alarm receiving terminal generates an alarm recording request when the alarm video telephone is connected. And the storage server receives the warning recording request sent by the warning receiving terminal based on the video networking protocol.

In the embodiment of the invention, the warning situation recording request can comprise information of an alarm party and information of an alarm receiving party, wherein the information of the alarm party comes from an alarm terminal and can comprise information such as an IP address of the alarm terminal, a first video network number, a first sub-equipment number and a first recording file name; the information of the alarm receiver comes from the alarm receiving terminal and can comprise information such as the MAC address of the alarm receiving terminal, the second video network number, the second sub-equipment number and the second recording file name.

Step S102a1, according to the alert recording request, sending a first recording permission request aiming at the information of the alert party to the streaming media server, and sending a second recording permission request aiming at the information of the alert party to the alert receiving terminal;

in an optional embodiment of the present invention, the alarm side information may specifically include a first video network number, and the alarm side information may specifically include a second video network number; the first video network number is allocated by the streaming media server and can be dynamic. The streaming media server can be connected with a plurality of alarm terminals, and in order to maintain the communication between the alarm terminals and the video network in the same time period, a plurality of first video network numbers which are registered in the video network can be stored in the streaming media server. When a certain alarm terminal needs to communicate with the video network, the streaming media server generates a binding relationship between the alarm terminal and the first video network number, and the alarm terminal with the first video network number is equivalent to a communication certificate in the video network and can communicate with an alarm receiving terminal in the video network. When the alarm video telephone is finished, the streaming media server can unbind the first video networking number from the alarm terminal, and the first video networking number can generate a binding relationship with other alarm terminals again. Because the alarm receiving terminal is positioned in the video network, the second video network number in the alarm receiving party information can be directly distributed by a video network server in the video network, can be static fixed and belongs to a fixed binding relation with the alarm receiving terminal.

Based on the above, the step S102a1 may specifically include the following sub-steps:

substep S102a1-1, after receiving the alert recording request, sending a first recording permission request for the first video network number to the streaming media server, and sending a second recording permission request for the second video network number to the alarm receiving terminal.

After receiving the alert recording request, a recording step is required, and a first recording permission request is sent to the streaming media server at first, and a second recording permission request is sent to the alarm receiving terminal. The first recording permission request comprises a first video network number which is in binding relation with the alarm terminal, and after the streaming media server receives the first video network number, the target alarm terminal can be determined, and the alarm video telephone which is currently called by the target alarm terminal can be determined. The second recording permission request comprises a second video network number of the alarm receiving terminal.

Step S102a2, receiving a first recording permission returned by the streaming media server in response to the first recording permission request, and a second recording permission returned by the alarm receiving terminal in response to the second recording permission request;

the recording authority can be related channel information of the alarm side audio and video stream of the alarm terminal, such as the length and content of the video stream channel or the audio and video channel. The streaming media server can acquire a first recording authority from a target alarm terminal after determining the target alarm terminal and the currently called alarm video telephone according to the video networking number; and in a similar way, the alarm receiving terminal returns the second recording authority to the storage server after receiving the second recording authority.

In order to facilitate the alarm terminal and the alarm receiving terminal to quickly return the corresponding recording authority, in the embodiment of the present invention, the alarm party information may further include a first sub-device number, and the alarm receiving party information may further include a second sub-device number. The first sub-device number may be understood as a routing tunnel identification. The first sub-device number may be divided into a first audio sub-device number and a first video sub-device number, and the encapsulated audio or video data packets are routed between the two endpoints of the tunnel through the public internet. The second sub-device number is interpreted based on the first sub-device number in the alarm party information, which is not described herein again.

During specific implementation, the streaming media server can determine a first recording authority of the audio and video stream of the alarm party in the alarm video telephone according to the first sub-equipment number. In the embodiment of the invention, the alarm terminal is provided with at least one audio channel and one video channel. Therefore, the first sub-device number can be further divided into a first audio channel identifier and a first video channel identifier, the streaming media server can rapidly determine the audio channel of the alarm terminal according to the first audio channel identifier, rapidly determine the audio channel of the alarm terminal according to the first video channel identifier, and obtain the first recording permission of the audio channel and the video channel of the target alarm terminal. Correspondingly, the alarm receiving terminal is also provided with at least one audio channel and one video channel. Therefore, the second sub-device number can be further divided into a second audio channel identifier and a second video channel identifier, and the alarm receiving terminal can return a second recording permission of the corresponding audio channel to the storage server according to the second audio channel identifier; and returning the second recording authority of the corresponding video channel to the storage server according to the second video channel identifier.

The first recording authority received by the storage server comprises the recording authority of one audio channel and one video channel of the alarm terminal, and the second recording authority comprises the recording authority of one audio channel and one video channel of the alarm terminal.

Step S102a3, according to the first recording authority, executing a first recording task of recording the audio and video stream of the alarm party of the alarm terminal in the alarm video telephone; and executing a second recording task of recording the alarm receiving party audio and video stream of the alarm receiving terminal in the alarm video telephone according to the second recording authority.

Step S102a3 may further specifically include the following sub-steps:

substep S102a3-1, when receiving the first recording right, executing a first recording task of recording the alarm party audio and video stream of the alarm terminal in the alarm video telephone according to the first sub-equipment number; and executing a second recording task of recording the alarm receiving party audio and video stream of the alarm receiving terminal in the alarm video telephone according to the second sub-equipment number when the second recording right is received.

Just because there is a sub-equipment number between the alarm terminal and the alarm receiving terminal, the alarm videophone can be connected between the alarm terminal and the alarm receiving terminal. Therefore, in the first recording task, the first recording task of recording the audio and video stream of the alarm party of the alarm terminal in the alarm video telephone is executed according to the audio and video channel corresponding to the first sub-equipment number. Specifically, the audio stream of the alarm terminal in the alarm video telephone is received through the audio channel corresponding to the first audio channel identifier, and the video stream of the alarm terminal in the alarm video telephone is received through the video channel corresponding to the first video channel identifier.

Correspondingly, in the second recording task, the second recording task of recording the alarm receiving party audio and video stream of the alarm receiving terminal in the alarm video telephone is executed according to the audio and video channel corresponding to the second sub-equipment number. Specifically, the audio stream of the alarm receiving terminal in the alarm video telephone is received through the audio channel corresponding to the second audio channel identifier, and the video stream of the alarm receiving terminal in the alarm video telephone is received through the video channel corresponding to the second video channel identifier.

Step S103a1, associating the alert party audio/video stream and the alert party audio/video stream with the alert videophone.

In an optional embodiment of the present invention, the alarm side information further includes a first recording file name, and the alarm receiving side information further includes a second recording file name; the first recording file name is named by the alarm receiving terminal aiming at the called alarm terminal, and can comprise the contents of alarm time, alarm place, alarm type (traffic accident, theft, robbery and the like), name of a user using the alarm terminal and the like. The second recording file number may be based on a corresponding explanation of the first recording file name in the alarm party information, which is not described herein in detail. Therefore, the method may specifically further comprise the steps of:

creating a corresponding first recording file and a corresponding second recording file according to the first recording file name and the second recording file name;

after receiving the warning recording request, the storage server extracts and obtains a first recording file name and a second recording file name from the warning recording request, and then corresponding first recording files and second recording files are created locally. In an optional embodiment of the present invention, the step S103a1 may specifically include the following sub-steps:

substep S103a1-1, storing the alarm side audio-video stream in the first recording file, and storing the alarm side audio-video stream in the second recording file;

substep S103a1-2, associating said first recorded file and said second recorded file with said alerting videophone.

In combination with the above steps, in a specific example of embodiment 1 of the present invention: aiming at two data sources, namely an alarm terminal A and an alarm receiving terminal B, in an alarm video telephone, after receiving an alarm recording request sent by the B, a storage server requests a streaming media server to record a first recording authority of an alarm party audio and video stream S1 of the A through a first video networking number and a first sub-equipment number in the alarm recording request; and directly requesting a second recording authority of the alarm party audio-video stream S2 from B through a second video network number and a second sub-equipment number in the alarm recording request, and then respectively establishing corresponding single-screen-division recording tasks according to the two recording authorities. In the first recording task, the storage server receives the S1 of the A by using the audio/video channel 1 corresponding to the first sub-device number, and uses the second recording task for recording the S2 of the B by using the audio/video channel 2 corresponding to the second sub-device number.

When the storage server receives the alert recording request, two corresponding recording files x1 and x2 are created according to the two recording file numbers in the alert recording request. After the storage server obtains the audio and video stream, S1 is stored in x1, and S2 is stored in x 2. Then x1 and x2 are associated with the alerting videophone, thereby realizing the correlation of S1 and S2

And then, according to the alarm resource code, finding a first recording file and a second recording file which are corresponding to the alarm video telephone, and extracting and obtaining a first recording file name of the first recording file and a second recording file name of the second recording file. And then the first recording file name and the second recording file name are assembled in pairs and packaged into the recording record of the alarm video telephone with the alarm resource code of # JQ 1001.

In an alternative embodiment of the present invention, step S301a2 further includes the following sub-steps:

substep S301a2-1, when receiving the resource obtaining request, judging whether a first recording file and a second recording file associated with the alarm videophone are stored;

and a substep S301a2-2, when storing a first recording file and a second recording file associated with the alerting videophone, assembling a first recording file name of the first recording file associated with the alerting videophone and a second recording file name of the second recording file associated with the alerting videophone in pairs, and packaging into a recording record of the alerting videophone.

Since the data stored in the storage server is relatively large, there may be a case where a part of the first recording file and the second recording file associated with the alert videophone are deleted, for example, the relevant recording file of the alert videophone sent relatively long will be deleted. Therefore, even if the user obtains the alert resource code, there may be a problem that there is no corresponding recording file. Therefore, when receiving the resource acquisition request, the storage server executes a judgment program to judge whether the first recording file and the second recording file associated with the alarm video telephone are stored, if yes, the relevant recording record is returned, and if not, the information of acquisition failure is returned to the on-demand terminal.

The above examples provide mainly the case where the alert resource code is known in advance to obtain the recorded record of the relevant alerting videophone. In practical applications, the user may not know the code, but only knows the corresponding alarm event, and therefore, the resource acquisition request of the embodiment of the present invention may further include an alarm feature. The alert feature may be for one alert videophone or for a group of alert videophones. For example, when the alert feature is for an alert videophone, the alert feature may be an IP address of an alert terminal in the alert videophone. The alert feature may be an alert screening condition when the alert feature is for a batch of alert videophones.

Based on the above, the substeps S301a2-1 to S301a2-2 are further optimized, and a method for obtaining batch recording records of the alarm videophone is also provided, specifically including the following steps:

when the storage server stores the first recording file and the second recording file associated with the alarm video telephone, the storage server can classify the recording files according to the alarm time and/or the alarm area and/or the alarm type so as to be called later.

According to the requirement, the resource acquisition request of the embodiment of the invention can also include alarm condition screening conditions, such as alarm condition time and/or alarm condition area and/or alarm condition type. And the storage server queries whether a first recording file and a second recording file which are corresponding to the alarm video telephone exist locally or not by taking the alarm time and/or the alarm area and/or the alarm type as screening conditions according to the resource acquisition request sent by the on-demand terminal. For example, the resource acquisition request includes screening information of a school, the storage server takes the warning area as the school as a screening condition, and queries a first recording file and a second recording file which are associated with the alarm video telephone and take all the warning areas as the school; for example, the resource acquisition request includes screening information that the warning area in 2018 is school, and the storage server queries all the first recording files and all the second recording files which are locally stored and are related to the warning videophone, wherein the warning area in 2018 is school, and the storage server uses 2018 and the school as screening conditions.

When the first recording file and the second recording file which are related to each other and correspond to the alarm time and/or the alarm area and/or the alarm type are inquired, the first recording file and the second recording file which are related to the same alarm video telephone under the classification (such as the alarm time and/or the alarm area and/or the alarm type) can be assembled in pairs and packaged into the recording records of the alarm video telephones one by one, and the alarm recording related resource list is formed.

Step S301a3, sending the recorded record of the alarm videophone to the on-demand terminal.

In the embodiment of the invention, the storage server can send the recording record of the alarm video telephone to the on-demand terminal based on the video networking fragment reliable transmission protocol, so that the on-demand terminal can conveniently display on-demand in a subsequent split screen mode. In practice, the storage server may send the recorded records of the plurality of alert videophones to the on-demand terminal, for example, send the alert recording associated resource list to the on-demand terminal.

And then, when receiving the triggering operation of the recording record of the on-demand alarm video telephone, the on-demand terminal dials two paths of on-demand video telephones respectively to the storage server, and then the storage server is respectively communicated with the two paths of on-demand video telephones. The specific implementation process of dialing two video-on-demand telephones will be described in detail later, and will not be described herein.

Step S302, in a video-on-demand telephone, sending an alarm audio and video stream associated with the alarm video telephone to the video-on-demand terminal; and in the other path of video-on-demand telephone, sending the audio and video stream of the alarm receiving party associated with the alarm video telephone to the video-on-demand terminal.

In the embodiment of the invention, after the storage server is connected with two paths of video-on-demand telephones dialed by a video-on-demand terminal, when only a first recording file and a second recording file associated with one alarm video telephone are stored in the storage server, the storage server can extract the audio and video stream of an alarm party of the alarm video telephone from the first recording file by default, and send the audio and video stream of the alarm party to the video-on-demand terminal through one path of video-on-demand telephone; and extracting the audio and video stream of the alarm receiving party of the alarm video telephone from a second recording file, and sending the audio and video stream of the alarm receiving party to the on-demand terminal through the other path of on-demand video telephone.

However, when a plurality of alarm party audio and video streams associated with the alarm videophone and the alarm party audio and video streams are stored in the storage server, the storage server cannot execute the sending task of the audio and video streams by default. In view of this situation, an embodiment of the present invention provides a scheme for demanding a corresponding audio/video by using a demand start signaling, and referring to fig. 4, an exemplary flowchart of embodiment 3 of an audio/video stream demand method according to an embodiment of the present invention is shown. Firstly, a storage server receives a videophone preparation signaling and replies; and the on-demand terminal continuously sends a telephone starting signaling to the storage server when the storage server is ready for the video telephone according to the reply sent by the storage server. If the storage server receives the on-demand starting signaling within the timeout time range, which indicates that the conversation between the storage server and the on-demand starting signaling is normal, step S302 is executed, and the alarm party audio and video stream associated with the alarm video telephone and the alarm receiving party audio and video stream are respectively sent to the on-demand terminal in two paths of on-demand video telephones. When the storage server receives the playing stop signaling in the two paths of video-on-demand telephones, the continuous transmission of the related audio and video stream is stopped. When the storage server receives the video telephone service stopping signaling aiming at the two paths of video telephone on demand respectively, the video telephone with the video telephone on demand terminal is interrupted, thereby completing the whole video telephone on demand process.

By integrating the steps S301 to S302, the embodiment of the invention provides a video-on-demand method for audio and video streams in the alarm video telephone from the perspective of a storage server, provides a recording record of the alarm video telephone capable of being on-demand for an on-demand terminal, establishes a two-way on-demand video telephone with the on-demand terminal, respectively sends two audio and video streams associated with the alarm video telephone in the two-way on-demand video telephone, and provides a core basis for realizing two-way on-demand and one-screen playing of alert resources for the on-demand terminal.
