Because the streaming media server 001 of the alarm command center can receive data of the internet, the streaming media server generally responds to a video call request sent by a mobile phone in an audio/video stream recording system of the video network, and the streaming media server 001 establishes a connection with the mobile phone 28 through one of a plurality of local virtual terminals. After receiving the video call request, the streaming media server 001 connected to the mobile phone 28 converts the video call request into data that can be transmitted in the video network, and transmits the data to the video network server, and converts the data into a video call request according to the video network protocol, which carries the terminal number 28 and the declared terminal number 322 of the mobile phone.
The video network server determines that the handset successfully connected the video call with the heuristic 322 by the following steps.
Referring to fig. 1, fig. 1 is a flowchart illustrating steps of connecting a video call according to an embodiment of the present application. The method is applied to a video network server.
Step S101: receiving a video call request sent by the internet terminal through the streaming media server; the video call request carries a terminal number of the video networking terminal and a terminal number of the Internet terminal;
when the streaming media server forwards the video call request to the video networking server, the streaming media server will add its own number 001. Further, the video call request converted to comply with the video networking protocol carries the terminal number 28 of the mobile phone, the declared terminal number 322, and the number 001 of the streaming server.
Step S102: forwarding the video call request to the video networking terminal according to the video networking terminal number;
step S103: receiving a call response returned by the video network terminal;
the switch 322 receives the video call request forwarded by the video network server, stores the terminal number 28 of the mobile phone and the number 001 of the streaming media server, and sends a call response to the video network server to notify the video network server that the video network server is ready to perform a video call, including turning on a camera and a microphone, starting a program for processing the video stream, and the like. It is apparent that the call answer also carries the handset's terminal number 28 and the declared terminal number 322.
Step S104: sending the call response to the internet terminal through the streaming media server;
the video network server sends the call response directly to the streaming media server 001, and the streaming media server 001 converts the call response into data conforming to the internet protocol and sends the converted call response to the mobile phone 28.
Step S105: and receiving a confirmation response sent by the Internet terminal through the streaming media server to determine that the video call between the Internet terminal and the video networking terminal is connected.
The mobile phone receives the call response, prepares for video call locally, such as starts a camera running program, starts a program for processing audio and video streams and the like, and sends a confirmation response to the streaming media server through the internet.
After receiving the acknowledgement sent by the mobile phone 28, the media server 001 converts the acknowledgement into a data format capable of being transmitted in the video network, and sends the converted acknowledgement to the video network server, and the video network server determines that the mobile phone 28 is connected with the video call of the declaration 322 after receiving the call acknowledgement and the acknowledgement.
The alarm receiver can also dial back the mobile phone 28 through the starting terminal 322, the starting terminal 322 dials the mobile phone 28 through 001-28, and the video call request is sent to the mobile phone 28 through the video networking server and the streaming media server 001 to establish call connection with the mobile phone again. The process of the specific video networking server confirming that the mobile phone 28 and the reminder terminal 322 successfully establish the video call is similar to the above steps S101 to S105, and this is not described in detail in this embodiment of the application.
After the mobile phone 28 and the lighting device 322 successfully establish the video call, the video networking server completes recording the audio and video stream of the current video call through the following steps.
Referring to fig. 2, fig. 2 is a flowchart illustrating steps of recording audio and video streams according to an embodiment of the present application.
Step S201: when the video call between the internet terminal and the video networking terminal is connected, a multicast address and a first channel key are issued to the streaming media server, and the multicast address and a second channel key are issued to the video networking terminal;
specifically, before issuing a multicast address and a first channel key to the streaming media server and issuing a multicast address and a second channel key to the video network terminal, it is further required to determine a channel for transmitting an audio/video stream of a current video call and a multicast address where the channel is located.
Transmitting the audio and video stream generated by the internet terminal and forwarded by the streaming media server through a first channel in the multicast address;
and transmitting the audio and video stream generated by the video networking terminal through a second channel in the multicast address.
The video network server has a plurality of multicast addresses, each multicast address also has a plurality of transmission channels, the first channel refers to a channel for transmitting audio and video streams generated by the mobile phone 28, and the audio and video streams generated by the mobile phone 28 are video streams of pictures recorded by a camera of the mobile phone and audio streams collected by a microphone of the mobile phone. The first channel key refers to a key of the first channel.
Similarly, the first channel refers to a channel for transmitting the audio/video stream generated by the lighting device 322, and the audio/video stream generated by the lighting device 322 is the video stream and the audio stream collected by the camera and the microphone connected to the lighting device 322. The first channel key refers to a key of the second channel.
In another embodiment of the present application, the first channel may include two channels, which respectively transmit a video stream of a picture recorded by a camera of a mobile phone and an audio stream collected by a microphone of the mobile phone; the second channel may also include two channels, which respectively transmit a camera captured video stream connected to the lighting 322 and an audio stream captured by a microphone connected to the lighting 322.
Step S202, receiving a recording request sent by the video network storage gateway; the recording request comprises the first channel key and the second channel key which are respectively acquired by the video network storage gateway from the streaming media server and the video network terminal;
the recording request is generated after the video network storage gateway acquires the first channel key and the second channel key.
Specifically, when the streaming media server 001 receives the multicast address and the first channel key, it generates a recording instruction, and because the streaming media server 001 already obtains the terminal numbers of the mobile phone 28 and the declaration 322 in the process of establishing the video call connection between the mobile phone 28 and the declaration 322, the recording instruction sent by the streaming media server 001 to the video network storage gateway carries the multicast address, the terminal number (28) of the internet terminal, and the terminal number (322) of the video network terminal.
The video network storage gateway finds the streaming media server 001 connected with the mobile phone 28 according to the terminal number (28) of the internet terminal in the recording request, and sends a first channel key obtaining request for obtaining the first channel key to the streaming media server 001. Then, according to the terminal number (322) of the video network terminal in the recording request, the declaration 322 is found, and a second channel key obtaining request for obtaining a second channel key is sent to the declaration 322.
The video network storage gateway generates a recording request and sends the recording request to a video network server, wherein the recording request comprises a multicast address, a first channel key and a second channel key. The video network storage gateway finds a channel for audio and video stream transmission to be recorded in the video network server according to the multicast address, the video network server verifies the first channel key and the second channel key, and after the verification is passed, the video network storage gateway can watch and store the audio and video stream generated by the mobile phone 28 and transmitted by the first channel and the audio and video stream generated by the declaration 322 and transmitted by the second channel at the current multicast address.
After the video network storage gateway records the audio and video streams transmitted by the mobile phone 28 and the heuristic 322 in a video call, the alarm command center can know the whole process and position environment of the alarm of the user using the mobile phone 28 more accurately, and meanwhile, the backtracking and investigation of the alarm situation can be performed more conveniently when needed at a later stage.
In the process of the video call, the audio and video streams generated by the mobile phone 28 and the heuristic 322 are transmitted in real time in the channel of the multicast address, so that the recording of the audio and video streams by the storage gateway of the video network means that the audio and video streams transmitted in real time in the channel of the multicast address are watched and collected in real time at the multicast address. The process of recording the audio/video stream by the storage network manager of the video network can be that the 1 st second and the 1 st + t are collected in sequence 1 Second, 1 st + 2 The method comprises the steps of 8230, storing the acquired audio and video stream data to the local of the video network storage gateway through the first channel and the second channel, wherein the audio and video stream data are recorded in the first channel and the second channel.
The embodiment of the application indicates that a video network storage gateway is in a video network server, a channel for transmitting audio and video streams of a video network terminal in real time records audio and video streams generated by the video network terminal in a video call, and indicates that the video network storage gateway is in the video network server, and a channel for transmitting the audio and video streams of an internet terminal in real time records the audio and video streams generated by the internet terminal in the video call; meanwhile, the video network storage gateway acquires a key of a channel for actually transmitting the audio and video stream generated by the video network terminal at the video network terminal, and acquires a key of a channel for actually transmitting the audio and video stream generated by the internet terminal at the streaming media server; the video network storage gateway can record the audio and video stream generated by the internet terminal after the video network server passes the verification of the first channel key, and the video network storage gateway can record the audio and video stream generated by the video network terminal after the video network server passes the verification of the second channel key.
In summary, the storage gateway of the video network records the real-time audio and video stream of the video call in the channel actually transmitting the audio and video stream after the multicast address where the actual transmission channel of the audio and video stream is located is verified by the actual key of the transmission channel of the audio and video stream in the video network server where the actual transmission channel of the audio and video stream is located. The video network is a safe and efficient network, so that the audio and video stream of the video call recorded in the video network server is safe and efficient, and the safety of recording the audio and video stream is further ensured by verifying a channel key for transmitting the audio and video stream.
Step S203: and under the condition that the first channel key and the second channel key pass the verification, indicating the video networking storage gateway to acquire the audio and video stream for carrying out the video call between the Internet terminal and the video networking terminal according to the multicast address.
Therefore, before instructing the storage gateway of the video network to obtain the audio and video stream for the video call between the internet terminal and the video network terminal according to the multicast address, the method further comprises:
responding to the recording request, and verifying the first channel key and the second channel key;
and the video network server responds to the recording request, respectively verifies a first channel key and a second channel key in the recording request to determine whether the first channel key and the second channel key belong to the keys of the channels under the current multicast address, and when the first channel key and the second channel key are verified, the video network server indicates that the video network storage gateway can record the audio and video streams transmitted by the first channel and the second channel at the current multicast address.
Specifically, when the first channel key is verified, the video network server instructs the video network storage gateway to view and record the video stream recorded by the camera of the mobile phone 28 and the audio stream collected by the microphone of the mobile phone 28 in the first channel.
When the second channel key is validated, the video networking server instructs the video networking storage gateway to view and record the video stream recorded by the camera connected to the video network storage gateway 322 and the audio stream captured by the microphone of the handset 28 on the second channel.
