Mobile terminal devices can be mobile phones, tablets, laptops, palmtops, vehicle-mounted terminal devices, wearable devices, ultra-mobile personal computers, netbooks, personal digital assistants, etc.; non-mobile terminal devices can be personal computers, televisions, etc.; The application implementation plan is not specifically limited.

Destination terminal: The terminal that initiates the video subscription request in the cascade conference.

Source terminal: In a cascaded conference, the terminal to which the video subscription is requested.

Source processor; a processor connected in communication with the source terminal.

Destination processor: the processor connected to the destination terminal in communication.

MRFC; Multimedia Resource Function Controller, multimedia resource controller.

MRFP: Multimedia Resource Function Processor, multimedia resource processor.

In addition, the following processors, source processors, and destination processors can be any MRFP (Multimedia Resource Processor) in Figure 2; the following controllers, source controllers, and destination controllers can be any of Figure 2 MRFC (Multimedia Resource Controller).

The following control module, source control module, and destination control module can be any MRFC (multimedia resource controller) in Figure 2; the processing module, source processing module, and destination processing module can be any MRFP (multimedia resource processing) in Figure 2器).

Please refer to Figure 1, Figure 2, and Figure 3, the destination terminal and the source terminal are located in the same processor, the processor is controlled by a controller, and the control is controlled by a conference terminal. The destination terminal subscribes to the video stream of the source terminal through the conference terminal.

An embodiment of the application provides a conference cascading method, including: step S100, a conference terminal receives a video subscription request and generates a first video subscription instruction; step S200, a controller generates a video stream delivery request according to the first video subscription instruction; step S300 The processor delivers the video stream according to the video stream delivery request, and generates a video stream delivery response; step S400, the controller generates a first subscription confirmation response according to the video stream delivery response, and the conference terminal generates a video subscription response according to the first subscription confirmation response.

The conference cascading method provided by the embodiments of the present application can realize video subscription between different terminals, and the destination terminal can subscribe to the video of any other terminal in the same processor.

For example, after the destination terminal joins the cascade conference, by sending a video subscription request to the conference terminal, the conference terminal generates a first video subscription instruction according to the video subscription request and sends it to the controller. When the destination terminal and the source terminal are controlled by the same processor, the processor delivers the video stream of the source terminal to the destination terminal to complete the forwarding of the video stream.

When the processor delivers the video stream of the source terminal to the destination terminal, the processor generates a first media transmission response and uploads it to the controller; the controller generates a video stream delivery response according to the first media transmission response, and uploads the video stream delivery response to Conference terminal. The conference terminal generates a video subscription response based on the response sent by the video stream, and sends the video subscription response back to the destination terminal.

Among them, the conference terminal can be a cascaded conference component or a processor equipped with a cascaded conference component. Several controllers are directly managed through the conference terminal, and each controller manages several processors, so that the upper module directly manages the lower module without using The additional agent module simplifies the processing flow.

The conference terminal is provided with a location information list of the processor, and sends a video subscription request to the processor according to the location information list. If the conference terminal does not indirectly manage the corresponding processor, the processor reports the location information of the processor and adds the location information to the location information list, which increases the complexity of the subscription function of the solution.

In some embodiments, the conference terminal may be an application server, which establishes data information exchange between the client terminal and the data server, and completes the data information exchange by interpreting and responding to XML. Among them, XML is an extensible markup language, which is used to mark up electronic files to make them structured.

The application server may include a Web server, daoArcIMS application server, and ArcIMS application server. The application server receives user requests and sends the user request to the data server through the protocol. The data server generates a response or instruction according to the user request and sends it to the terminal Or the controller. The application server can concurrently process multiple user requests to process multiple video subscription requests in the cascaded conference at the same time.

For example, in a multi-party video conference, the conference terminal (application server) is cascaded with multiple controllers, and each controller is cascaded with multiple processes to construct the basic architecture of the multi-party video conference.

Multiple destination terminals respectively subscribe to the source terminal controlled by the same processor, multiple destination terminals respectively upload video subscription requests to the conference terminal or application server, and the conference terminal or application server generates the first video subscription corresponding to the video subscription request The instruction is issued to the corresponding controller. The multiple controllers generate a video stream delivery request according to the corresponding first video subscription instruction, so as to control the corresponding processor to send the video stream, so as to complete the video stream delivery of multiple video subscriptions at the same time.

In some embodiments, the controller may concurrently process multiple first video subscription instructions and generate a corresponding video stream delivery request, and the processor delivers the video stream to the corresponding destination terminal according to the corresponding video stream delivery request.

Please refer to FIG. 2, FIG. 4, and FIG. 5. In some embodiments, the destination terminal and the source terminal are located in different processors, and the different processors are controlled by the same controller. Step S200: The controller generates a video stream delivery request according to the first video subscription instruction, and further includes: Step S201: The controller generates a first media transmission request according to the first video subscription instruction; Step S202: The video stream is sent to the destination processor and a first media transmission response is generated; step S203, the controller generates a first media reception request according to the first media transmission response; step S204, the destination processor receives the video stream according to the first media reception request.

The controller sends the first media sending request to the source processor to control the source processor to send the video stream of the destination terminal to the destination processor. The destination processor receives the video stream processed by the source according to the first media receiving request of the controller. Among them, a media channel is set between the destination processor and the source processor, so that video streaming can be performed between the destination processor and the source processor.

For example, when the destination terminal sends a video subscription request to the conference terminal, the first video subscription instruction is issued to the controller through the same conference terminal, and the controller generates the first media sending request according to the first video subscription instruction; the source processor according to the first video subscription instruction The media sending request sends the video stream of the source terminal to the destination processor, and generates a first media sending response.

When the controller receives the first media transmission response, the controller generates the corresponding first media reception request and sends it to the destination processor; when the destination processor receives the first media reception request, the destination processor starts to receive the corresponding video stream, To pre-store the video stream in the designated area.

In some embodiments, the identity verification string corresponding to the destination processor or the destination terminal is set in the first media sending request to prohibit the source processor from sending the video stream to the destination processor when the destination terminal has no video subscription rights .

For example, when the source terminal is a restricted terminal and the destination terminal does not have the corresponding video subscription authority, the controller issues the first media sending request to the source processor, and the source processor uses the identity check character in the first media sending request The string verifies the identity of the destination terminal or destination processor. If the destination terminal has video subscription rights to the source terminal, the source processor sends the video stream of the source terminal to the destination processor according to the first media sending request, and generates a corresponding subscription response; if the destination terminal does not have a video to the source terminal When subscribing to the authority, the source processor determines that the first media sending request is an invalid request, and generates a corresponding subscription response.

Wherein, when the destination terminal has no video subscription right to the source terminal, the first media sending response generated by the source processor is a response without subscription right. The video subscription response generated by the conference terminal according to the response without subscription authority is still a response without subscription authority, and the response without subscription authority is returned to the destination terminal to remind the destination terminal that it does not have the video subscription authority to the source terminal temporarily.

In some embodiments, when the destination terminal receives a response without subscription permission, the destination terminal may upload a video subscription permission request to the conference terminal to obtain the video subscription permission corresponding to the source terminal. After the destination terminal obtains the corresponding video subscription authority, the conference terminal re-issues the first video subscription instruction to the controller to complete the video subscription of the destination terminal to the source terminal.

In some embodiments, there is a terminal authority list in the conference terminal. When the destination terminal grants video subscription authority to the source terminal, the conference terminal verifies the identity verification string in the video subscription request to determine whether the destination terminal has a corresponding The video subscription permission of the source terminal. If the destination terminal has the video subscription authority corresponding to the source terminal, the conference terminal generates the first video subscription instruction according to the video subscription request and sends it to the corresponding controller; if the destination terminal does not have the video subscription authority corresponding to the source terminal, the conference terminal The video subscription request generates a response without subscription permission and sends it back to the destination terminal.

The destination terminal obtains the video subscription permission corresponding to the source terminal by uploading the video subscription permission request, and updates the terminal permission list in the conference terminal to update the subscription permission information of the destination terminal to the terminal permission list.

Please refer to FIG. 2, FIG. 4, and FIG. 6. In some embodiments, the destination terminal is controlled by the destination processor, the source terminal is controlled by the source processor, and the destination processor and the source processor are controlled by the same controller.

After the destination processor receives the first media reception request, the destination processor starts to receive the video stream from the source processor, and generates a first media reception response and uploads it to the controller. The controller generates a video stream delivery request according to the first media reception response and delivers it to the destination processor, and the destination processor delivers the video stream of the source terminal to the destination terminal according to the video stream delivery request.

When the destination processor receives the subscribed video stream, it requests to control the delivery of the video stream through a video stream delivery request, so as to avoid the situation that the destination processor does not receive the video stream and the destination processor sends the video stream to the destination terminal, resulting in communication Occupation of the channel.

For example, while the destination processor pre-stores the video stream, the destination processor generates a first media reception response and uploads it to the controller. By returning the first media reception response to the controller, the controller generates a video stream delivery response according to the first media reception response. And the controller delivers the video stream delivery response to the destination processor, and the destination processor delivers the video stream to the designated destination terminal according to the video stream delivery response.

The destination processor delivers the video stream to the designated destination terminal according to the video stream delivery request, so as to prevent the video stream from being sent to other terminals by mistake, thereby ensuring the accuracy of information transmission. For example, a tag string corresponding to the destination terminal is set in the video stream delivery request, and the destination processor selects the terminal from which the video stream is delivered based on the tag string, and delivers the video stream to the corresponding terminal to complete the video stream in the video subscription. Issued.

For example, there is an identity verification string in the video stream delivery response, and the destination processor delivers the video stream to the designated destination terminal based on the identity verification string to prevent the destination processor from delivering the video stream to other than the destination terminal. Other terminals. If the video stream is sent to other terminals by mistake, the video subscription of the destination terminal may fail and the storage resources of other terminals may be occupied.
