Thus, alert resource codes, i.e., # JQ1001, may be included in the resource acquisition request.

Step S301a2, according to the resource obtaining request, assembling a first record file name of a first record file associated with the alarm video phone and a second record file name of a second record file associated with the alarm video phone, and packaging the first record file name and the second record file name as record records of the alarm video phone;

In the embodiment of the present invention, after the storage server parses the resource acquisition request, the alert resource code, for example, # JQ1001, may be obtained. And then finding out a corresponding first recorded file and a corresponding second recorded file which are associated with the alarm video telephone according to the alarm condition resource code, and extracting and obtaining a first recorded file name of the first recorded file and a second recorded file name of the second recorded file. And then the first recorded file name and the second recorded file name are assembled in pairs, and the record is packaged into the record of the alarm video telephone with the alarm resource code of # JQ1001.

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

step S301a2-1, judging whether a first recorded file and a second recorded file associated with the alarm videophone are stored or not when the resource acquisition request is received;

in the substep S301a2-2, when the first record file and the second record file associated with the alarm video phone are stored, the first record file name of the first record file associated with the alarm video phone and the second record file name of the second record file associated with the alarm video phone are assembled in pairs and packaged into the record of the alarm video phone.

Due to the large data stored by the storage server, there may of course be cases where a portion of the first recorded file and the second recorded file associated with the alerting videophone are deleted, such as when the associated recorded file of a relatively long-transmitted alerting videophone is deleted. Therefore, even if the user obtains the alert resource code, there may be a problem that there is no corresponding recorded file. Therefore, when the storage server receives the resource acquisition request, a judging program is executed to judge whether the first recorded file and the second recorded file associated with the alarm video telephone are stored or not, if yes, the related recorded records are returned, and if no, the acquisition failure information is returned to the on-demand terminal.

The above examples mainly provide the case of knowing the alert resource code in advance to obtain a recorded record of the relevant alert videophone. In practical applications, the user may not know the code, but only the corresponding alarm event, so the resource acquisition request of the embodiment of the present invention may further include an alarm condition feature. The alarm condition feature can be aimed at an alarm videophone or a group of alarm videophones. For example, when the alarm condition feature is specific to an alarm video phone, the alarm condition feature may be an IP address of an alarm terminal in the alarm video phone. When the alert feature is for a batch of alert videophones, the alert feature may be an alert screening condition.

Based on the above, the sub-steps S301a2-1 to S301a2-2 are further optimized, and a method for obtaining the recording batch of the alarm videophone is also provided, and specific examples are as follows:

when the storage server stores the first recorded file and the second recorded file which are associated with the alarm video telephone, the recorded files can be classified by alarm time and/or alarm area and/or alarm type so as to be called later.

According to needs, the resource acquisition request of the embodiment of the invention can also comprise alert screening conditions, such as alert time and/or alert area and/or alert type. And the storage server inquires whether a first recorded file and a second recorded file which are relevant to the alarm video telephone exist locally or not according to the resource acquisition request sent by the on-demand terminal and by taking the alarm time and/or the alarm area and/or the alarm type as screening conditions. For example, the resource obtaining request includes screening information of a school, the storage server uses alert areas as screening conditions of the school, and queries all local alert areas as first recorded files and second recorded files of the school, which are associated with the alert videophone; for example, the resource obtaining request includes screening information of the alert condition area in 2018 as a school, and the storage server uses 2018 and the school as screening conditions to query all the first recorded files and the second recorded files associated with the alert videophone of the alert condition area in 2018 which are locally stored as the school.

When the first record file and the second record file which are associated with each other and correspond to the alarm time and/or the alarm area and/or the alarm type are inquired, the embodiment of the invention can assemble the first record file and the second record file which are associated with the same alarm video telephone under the classification (such as the alarm time and/or the alarm area and/or the alarm type) in pairs, and package the first record file and the second record file into record records of the alarm video telephone one by one, namely form an alarm record associated resource list.

Step S301a3, transmitting the record of the alarm video phone to the on-demand terminal.

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

And then, when receiving triggering operation of recording records of the video-on-demand alarm video telephone, the video-on-demand terminal dials two paths of video-on-demand video telephone to the storage server respectively, and then the storage server connects the two paths of video-on-demand video telephone respectively. The specific implementation process of dialing two video-on-demand calls will be described in detail later, and will not be repeated here.

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

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

However, when the storage server stores a plurality of alarm audio/video streams associated with the alarm videophone and the alarm receiving audio/video streams, the storage server cannot execute the transmission task of the audio/video streams by default. In view of this situation, the embodiment of the present invention provides a solution for ordering corresponding audio and video by using an order start signaling, and referring to fig. 4, an example flowchart of an audio and video stream ordering method embodiment 3 of the embodiment of the present invention is shown. Firstly, the storage server receives the video telephone preparation signaling and replies; and the on-demand terminal continues to send 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 order start signaling within the timeout period, which indicates that the conversation between the two is normal, step S302 is executed, and the alarm party audio/video stream and the alarm receiving party audio/video stream associated with the alarm video telephone are respectively sent to the order terminal in the two paths of order video telephones. And stopping continuous transmission of the related audio and video streams when the storage server receives the playing stopping signaling in the two-way video-on-demand telephone. When the storage server receives the video telephone service stopping signaling aiming at the two video telephone on demand, the video telephone of the video telephone on demand terminal is interrupted, so that the whole video on demand process is completed.

Integrating the steps S301 to S302, the embodiment of the invention provides an on-demand method for audio and video streams in the alarm video telephone from the perspective of a storage server, provides a 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, completes the respective transmission of two audio and video streams associated with the alarm video telephone in the two-way on-demand video telephone, and provides a core foundation for the on-demand terminal to realize the two-way on-demand and on-screen playing of alarm condition resources.

Example 4:

based on the same inventive concept as embodiments 1 to 3, referring to fig. 5, a flowchart illustrating steps of embodiment 4 of an audio/video stream on demand method according to an embodiment of the present invention may be applied to an on demand terminal, where the on demand terminal is connected to a storage server, a recording record of an alarm video phone is preset in the on demand terminal, and the alarm video phone is associated with an alarm party audio/video stream and a receiver audio/video stream, and the method specifically may include the following steps:

step S501, when receiving triggering operation of recording record of video-on-demand alarm, dialing two paths of video-on-demand video calls to the storage server;

Recording records of the alarm video telephone are displayed on a display screen of the video-on-demand terminal, and triggering operation aiming at the recording records of the alarm video telephone can be that a user adopts a remote controller to order on the display screen, or can be that voice-controlled video-on-demand or touch screen video-on-demand is performed. The manner of on-demand is not limited herein.

The record of the alarm video telephone displayed by the on-demand terminal can be one record or a plurality of records. In an optional embodiment of the present invention, an alert recording associated resource list is stored in the on-demand terminal, and a recording record of the alert videophone is recorded in the alert recording associated resource list;

the step S501 may include the following sub-steps:

and when receiving triggering operation of ordering the recording records of the target alarm videophones in the alarm condition recording associated resource list, dialing two paths of video-on-demand phones to the storage server.

In the embodiment of the invention, the on-demand terminal displays the record records of the alarm video phones, and the record records of the alarm video phones are sequentially arranged on the on-demand terminal to form an alarm condition record associated resource list. If the user requests the program through the remote controller, the remote controller can be provided with 0-9 number keys, a last item and a next item selection key, a key for returning to the last interface, a pause key, an end key and the like. The user can send corresponding on-demand selection signaling, on-demand start signaling or stop signaling and the like to the on-demand terminal by operating keys on the remote controller.

The target alarm videophone is one selected by the user from the alarm record associated resource list. For example, the number of the record of the target alarm video telephone is 01, and the user can directly select the record of the alarm video telephone by directly pressing the number key 1 on the remote controller.

In an optional embodiment of the present invention, two sub-device numbers are set in the on-demand terminal, and a plurality of virtual terminal numbers are set in the storage server; the step S501 may further comprise the sub-steps of:

sub-step S501a1, when receiving a trigger operation of recording a video-on-demand alarm video phone, sending a video phone preparation message to the storage server;

the video-on-demand terminal generates a video telephone preparation message according to the triggering operation of the user, and can send the video telephone preparation message to the storage server based on the video networking protocol.

Sub-step S501a2, receiving two target virtual terminal numbers in idle states returned by the storage server for the videophone preparation message, where the target virtual terminal numbers are determined from the multiple virtual terminal numbers;

sub-step S501a3, dial video-on-demand telephone to two said target virtual terminal numbers using two said sub-device numbers, respectively.

Substep S501a2 through substep S501a3 provide a scheme in which the on-demand terminal forces the on-demand video phone to the storage server. When receiving the video telephone preparation message, the storage server is equivalent to receiving a forced command for establishing the video telephone, and automatically finds two target virtual terminal numbers which are not in a service state (idle state) from a plurality of locally set virtual terminal numbers according to the video telephone preparation message, and then returns the target virtual terminal numbers to the on-demand terminal. And when the video-on-demand terminal receives the two target virtual terminal numbers, the storage server is considered to be ready for starting the video-on-demand video telephone, namely, the local two sub-equipment numbers dial the video-on-demand telephone to the two target virtual terminal numbers respectively.

Step S502, in a video-on-demand telephone, receiving an alarm party audio/video stream associated with the alarm video telephone sent by the storage server; and in another video-on-demand telephone, receiving the police receiving party audio-video stream associated with the alarming video-on-demand telephone sent by the storage server.

When the storage server only stores the first recorded file and the second recorded file associated with the on-demand alarm video phone, the on-demand terminal can directly receive two paths of audio and video streams sent by the storage server.

When a plurality of alarm party audio-video streams and alarm receiving party audio-video streams associated with the alarm videophone are stored in the storage server, in an optional embodiment of the present invention, the method may further include the steps of:

step 1, in a video-on-demand telephone, a first video-on-demand starting signaling is sent to the storage server; and in another video-on-demand telephone, sending a start signaling for a second video-on-demand to the storage server;

the step S502 may further include the sub-steps of:

step S502a1, in a video-on-demand telephone, receiving an alarm party audio-video stream associated with the alarm video telephone returned by the storage server aiming at the first video-on-demand starting signaling; and in the other video-on-demand telephone, receiving an alarm receiving party audio-video stream associated with the alarm video-on-demand telephone returned by the storage server aiming at the second video-on-demand starting signaling.

The embodiment of the invention adopts the on-demand starting signaling to distinguish a plurality of alarm party audio-video streams associated with the alarm video telephone from the alarm party audio-video streams associated with the alarm video telephone, and respectively on-demand corresponding alarm party audio-video streams and alarm party audio-video streams associated with the target alarm video telephone. Specific examples of embodiments of the present invention are as follows:

In this example, for example, the obtained target virtual terminal numbers are T1 and T2, the sub-device numbers for dialing the video-on-demand phones are P1 and P2, and the two video-on-demand phones are: video telephone between P1 and T1, video telephone between P2 and T2. The alarm party audio-video stream in the first recorded file associated with the alarm video telephone is S1, and the alarm party audio-video stream in the second recorded file is S2. In a video-on-demand telephone, P1 sends a first on-demand signaling of S1 on demand to T1; in another video-on-demand telephone, P2 sends a second on-demand signaling of on-demand S2 to T2. S1 is then received by P1 and S2 is received by P2.

In an embodiment of the present invention, after receiving the alarm audio-video stream and the alarm receiving audio-video stream associated with the alarm videophone, the method may further include the steps of:

and step 2, the alarm party audio and video streams and the alarm receiving party audio and video streams associated with the alarm video telephone are split and played.

Based on the content of step S102a2 in the embodiment of the present invention, the number of sub-devices of the on-demand terminal also corresponds to one audio/video channel (one audio channel and one video channel), so how many sub-devices of the on-demand terminal represent the number of audio/video streams that can be played currently, i.e. the number of split-screen displays. The embodiment of the invention uses the two sub-equipment numbers to dial the video-on-demand telephone respectively, can realize that the audio and video streams transmitted by the channels corresponding to the two sub-equipment numbers are directly put on the two display screens of the video-on-demand terminal to be played, does not involve the coding and decoding process, and realizes the effect that one video-on-demand terminal plays the audio and video picture of the alarm terminal and the audio and video picture of the alarm receiving terminal in one alarm video telephone on the same screen.
