Referring to fig. 1, a flowchart illustrating steps of a video processing method according to a first embodiment of the present invention is shown. The video processing method of the embodiment of the invention can be applied to a supervision server.
The video processing method of the embodiment of the invention can comprise the following steps:
When the video of the video source terminal needs to be displayed on the display terminal, the user can set the display terminal identification and the video source terminal identification and other related parameters on the client. For example, the client may provide an input box, and the user may input the display terminal identifier and the video source terminal identifier and other related parameters in the input box, or the client may provide a selection list, and the user may select the display terminal identifier and the video source terminal identifier and other related parameters in the list.

The first video receiving instruction is used for indicating the display terminal to start receiving video services.
In the video network, each terminal can be bound with a video network number, and the video network number is used as the unique identifier of the terminal in the video network. The terminal can send or receive video by using the video networking number, and one video networking number is used for sending or receiving one path of video. In the embodiment of the invention, when the display terminal is registered, at least two video networking sub-numbers can be configured for the video networking number of the display terminal, the display terminal can send or receive videos by utilizing the video networking sub-numbers, and one video networking sub-number is used for sending or receiving one path of video.

When the video source terminal identifications are at least two, the video source terminals are at least two, so that it can be determined that the display terminal will receive at least two paths of videos. In this case, if the display terminal receives the video using the video network number, it is impossible to receive at least two videos. Therefore, the monitoring server may generate a second video receiving instruction based on the video networking protocol and transmit the second video receiving instruction to the display terminal. And the second video receiving instruction is used for indicating the display terminal to receive the video by using the video network sub-number. And after receiving the second video receiving instruction, the display terminal receives the video by using the video network sub-number.

In the embodiment of the invention, at least two video networking sub-numbers are set for the video networking number of the display terminal, and the monitoring server is utilized to control the display terminal to receive the video through the video networking sub-numbers, so that at least two paths of videos can be received and displayed on the display terminal, the flexibility is higher, and the service requirements are further met.
Example two
In the embodiment of the invention, the supervision server interacts with the client through the Internet, the supervision server interacts with the video network server through the video network, and the video network server interacts with the terminal in the video network through the video network.
Referring to fig. 2, a flowchart illustrating steps of a video processing method according to a second embodiment of the present invention is shown.
The video processing method of the embodiment of the invention can comprise the following steps:
In the video network, various services in the video network are uniformly managed by a video network server. If the terminal is to be added into the video network, the terminal needs to be registered in the video network server. After the terminal is successfully registered, the video network server distributes information such as video network numbers and the like for the successfully registered terminal.
If the supervision server is to be added into the video network, the virtual terminal can be configured in the supervision server in advance, and the virtual terminal is registered in the video network server. And after the registration is successful, the video networking server allocates a video networking number for the virtual terminal.
The display terminal and the video source terminal are registered in the video network server in advance. For the display terminal, if the multi-channel video needs to be received and displayed, the video network server allocates a video network number for the display terminal, and adds at least two video network sub-numbers for the video network number of the display terminal. For the video source terminal, the video networking server can distribute a video networking number for the video source terminal, and certainly, at least two video networking sub-numbers can be added to the video networking sub-numbers of the video source terminal according to actual requirements. Alternatively, the video network sub-number may be in the form of, for example, video network number #1, video network number #2, etc.
When the video of the video source terminal needs to be displayed on the display terminal, the user can execute corresponding operation on the client so as to trigger the client to generate a terminal information obtaining request based on the internet protocol. For example, the client may provide a terminal information obtaining button, and a user may trigger the client to generate a terminal information obtaining request after clicking the terminal information obtaining button. And the client sends a request for acquiring the terminal information to the supervision server through the Internet. Alternatively, the request for acquiring the terminal information may be a request in an HTTP (Hyper Text Transfer Protocol) format.
The monitoring server presets terminal information to be processed, the terminal information may include terminal identification, Media Access Control (MAC) address of the terminal, and the like, and the terminal information may be in the form of a list and the like. And after receiving the terminal information acquisition request, the supervision server returns the preset terminal identification to the client through the Internet.
And 203, receiving a video display request based on an internet protocol sent by a client, and analyzing to obtain a display terminal identifier and a video source terminal identifier carried by the video display request.
And the client displays the received terminal identification. The user selects a display terminal identifier for receiving and displaying the video and a video source terminal identifier for acquiring and sending the video from the terminal identifiers, and the client is triggered to generate a video display request based on the Internet protocol, wherein the video display request carries the display terminal identifier and the video source terminal identifier. Alternatively, the video display request may be a request in HTTP format. And the client sends the video display request to the supervision server.
After receiving the video display request, the monitoring server analyzes the video display request according to an internet protocol format (such as an HTTP format) to obtain a display terminal identifier and a video source terminal identifier carried therein. The display terminal identification can be the video network number of the display terminal, and the identification of the video source terminal can be the video network number of the video source terminal.
And 204, inquiring the state of the display terminal from the network management server.
If the display terminal needs to receive and display the video, the display terminal needs to be online and the service is idle, and the idle service means that other video services are not carried out.
The embodiment of the invention can also be provided with a network management server, the network management server can interact with the video network server through the video network, and the network management server can interact with the supervision server through the internet. The network management server can be used for maintaining the state of each terminal and correspondingly recording the terminal identification and the terminal state. For example, because the video network server centrally manages the video network service, the video network server can record the state of each terminal in real time, and the network management server can obtain the state of each terminal from the video network server.
The supervision server can inquire the state of the display terminal from the network management server after analyzing the video display request and obtaining the display terminal identifier. In the implementation, the supervision server generates a state query request based on an internet protocol, and sends the state query request to the network management server through the internet. The network management server analyzes the state query request, the state query request can carry the display terminal identification, the network management server queries the state corresponding to the display terminal identification from the record of the network management server, namely the state of the display terminal, and the network management server returns the state of the display terminal to the monitoring server through the internet. Alternatively, the status query request may be a request in HTTP format.
The state of the terminal may include online and ongoing traffic, online and idle traffic, offline, etc.
And when the inquired state of the display terminal is online and the service is idle, the monitoring server determines that the display terminal can receive and display the video. In this case, the monitoring server generates the first video reception instruction based on the video networking protocol. In the implementation, the monitoring server packages the display terminal identifier and the first indication information based on a video networking protocol to obtain a first video receiving instruction. Certainly, the first video receiving instruction may also carry information such as an MAC address (source MAC address) of the virtual terminal, an MAC address (destination MAC address) of the display terminal, and a virtual terminal identifier, where the virtual terminal identifier may be a video network number of the virtual terminal. The first indication information is used for indicating the display terminal to start receiving the video service, so that the first video receiving instruction is used for indicating the display terminal to start receiving the video service.
And the supervision server sends the first video receiving instruction to the video networking server through the virtual terminal. After receiving the first video receiving instruction, the video networking server analyzes the display terminal identification to know that the first video receiving instruction is to be sent to the display terminal, so that the video networking server forwards the first video receiving instruction to the display terminal according to the display terminal identification. After receiving the first video receiving instruction, the display terminal analyzes the first video receiving instruction to obtain first indication information, and knows that the video receiving service is to be started.
And when the inquired state of the display terminal is online and the service is in progress or the state of the display terminal is offline, the monitoring server determines that the display terminal can not receive and display the video temporarily. In this case, the supervision server may generate a video display response based on the internet protocol and return the video display response to the client. The video display response can carry indication information that the display terminal cannot display the video, and the client can show the indication information to the user.
And step 206, when the video source terminals are at least two in number, generating a second video receiving instruction based on a video networking protocol, and sending the second video receiving instruction to the display terminal.
The monitoring server acquires the number of the video source terminal identifications, namely the number of the video source terminals after sending the first video receiving instruction to the display terminal.
When the video source terminal identifications are at least two, the supervision server determines that the display terminal is to receive the video by using the video networking sub-number. In this case, the monitoring server generates the second video reception instruction based on the video networking protocol. In the implementation, the monitoring server packages the display terminal identifier and the second indication information based on the video networking protocol to obtain a second video receiving instruction. Certainly, the second video receiving instruction may also carry information such as a MAC address (source MAC address) of the virtual terminal, a MAC address (destination MAC address) of the display terminal, and a virtual terminal identifier. The second indication information is used for indicating the display terminal to receive the video by using the video network subnumber, so that the second video receiving instruction is used for indicating the display terminal to receive the video by using the video network subnumber.
And the supervision server sends the second video receiving instruction to the video networking server through the virtual terminal. After receiving the second video receiving instruction, the video networking server analyzes the display terminal identification to know that the second video receiving instruction is to be sent to the display terminal, so that the video networking server forwards the second video receiving instruction to the display terminal according to the display terminal identification. And after receiving the second video receiving instruction, the display terminal analyzes the second video receiving instruction to obtain second indication information, and knows that the video is to be received by using the video networking number. Therefore, when a video is sent to the display terminal, the display terminal receives the video by using the video network sub-number. One of the video network sub-numbers is used for receiving a video.
When one video source terminal identifier is identified, one video source terminal can determine that the display terminal will receive one path of video. The regulation server determines that the display terminal can receive video using the video network number. Because the display terminal receives the video by using the video networking sub-number under the default condition, the supervision server does not send a second video receiving instruction to the display terminal any more, so that the display terminal receives the video by using the video networking number.
And step 207, generating a video sending instruction which corresponds to the current video source terminal identification and carries the display terminal identification based on a video networking protocol for each video source terminal identification, and sending the video sending instruction to the current video source terminal corresponding to the current video source terminal identification.
And the supervision server respectively processes each video source terminal identifier, and the processing process of each video source terminal identifier is the same. In the embodiment of the invention, the identifier of the video source terminal which is being processed is called as the current video source terminal identifier, and the video source terminal corresponding to the current video source terminal identifier is called as the current video source terminal.
And aiming at the current video source terminal identification, the supervision server generates a video sending instruction corresponding to the current video source terminal identification based on the video networking protocol. In the implementation, the monitoring server encapsulates the current video source terminal identifier, the display terminal identifier and the third indication information based on the video networking protocol to obtain a video sending instruction corresponding to the current video source terminal identifier. Certainly, the video sending instruction may also carry information such as a MAC address (source MAC address) of the virtual terminal, a MAC address (destination MAC address) of the current video source terminal, and a virtual terminal identifier. The third indication information is used for indicating the current video source terminal to send the video to the display terminal, so that the video sending instruction is used for indicating the current video source terminal to send the video to the display terminal.
And the supervision server sends the video sending instruction corresponding to the current video source terminal identification to the video networking server through the virtual terminal. After receiving a video sending instruction corresponding to the current video source terminal identification, the video networking server analyzes the current video source terminal identification to know that the video sending instruction is to be sent to the current video source terminal, so that the video networking server forwards the video sending instruction to the current video source terminal according to the current video source terminal identification.
And after receiving the video sending instruction, the current video source terminal analyzes the video sending instruction to obtain a display terminal identifier and third indication information, and knows to send the video to the display terminal. Therefore, the current video source terminal starts to collect the video and sends the video to the display terminal. In the sending process, the current video source terminal encapsulates the collected video into a data packet and sends the data packet to the video networking server, wherein the data packet carries information such as the display terminal identification, the MAC address (source MAC address) of the current video source terminal, the MAC address (destination MAC address) of the display terminal and the like. The video network server can forward the data packet to the display terminal according to the identifier of the display terminal.
Each video source terminal sends video to the display terminal, and the display terminal receives one path of video by using one video network sub-number, so that the display terminal can receive multiple paths of video sent by a plurality of video source terminals simultaneously.
