Since only one cascade port is provided in a general cascade conference, and video streams of a plurality of signal channels cannot simultaneously pass through the same cascade port, a terminal in the cascade conference cannot randomly subscribe video streams of other terminals.
Based on this, embodiments of the present application provide a conference cascading method, a cascading conference system, a terminal, and a computer-readable storage medium, so that the terminal can select to view a video or multiple pictures of the terminal on any one processor in a cascading conference.

A source terminal: in the cascading conference, the terminal which is requested to subscribe to the video.
A source processor; and the processor is in communication connection with the source terminal.
The purpose processor: and the processor is in communication connection with the destination terminal.

In addition, the processor, source processor, and destination processor described below may be any one of the MRFPs (multimedia resource processors) in fig. 2; the controller, source controller, and destination controller described below may be any of the MRFCs (multimedia resource controllers) in fig. 2.

Referring to fig. 1, 2 and 3, the destination terminal and the source terminal are located in the same processor, and the processor is controlled by a controller and a conference terminal. And the destination terminal subscribes the video stream of the source terminal through the conference terminal.
The embodiment of the application provides a conference cascading method, which comprises the following steps: step S100, a conference terminal receives a video subscription request and generates a first video subscription instruction; step S200, the controller generates a video stream issuing request according to the first video subscription instruction; step S300, the processor issues the video stream according to the video stream issuing request and generates a video stream issuing response; and S400, the controller generates a first subscription confirmation response according to the video stream issuing response, and the conference terminal generates a video subscription response according to the first subscription confirmation response.
The conference cascading method provided by the embodiment of the application can realize the video subscription among different terminals, and the target terminal can subscribe videos of other optional terminals in the same processor.
For example, after the destination terminal joins the cascading conference, the conference terminal generates a first video subscription instruction according to the video subscription request and sends the first video subscription instruction to the controller by sending the video subscription request to the conference terminal. When the destination terminal and the source terminal are controlled by the same processor, the processor transmits the video stream of the source terminal to the destination terminal so as to complete the forwarding of the video stream.
When the processor sends the video stream of the source terminal to the destination terminal, the processor generates a first media sending response and uploads the first media sending response to the controller; the controller generates a video stream issuing response according to the first media sending response, and uploads the video stream issuing response to the conference terminal. And the conference terminal generates a video subscription response according to the response sent by the video stream and transmits the video subscription response back to the destination terminal.
The conference terminal can be a cascade conference component or a processor provided with the cascade conference component, the conference terminal directly manages the plurality of controllers, and each controller manages the plurality of processors, so that the upper layer module directly manages the lower layer module, and an additional agent module is not used, thereby simplifying the processing flow.
The conference terminal is provided with a position information list of the processor and sends a video subscription request to the processor according to the position information list. If the conference terminal does not indirectly manage the corresponding processor, the processor reports the position information of the processor and adds the position information to the position information list, so that the complexity of the subscription function of the scheme is increased.
In some embodiments, the conference terminal may be an application server, and establishes data information communication between the client terminal and the data server, and completes the data information communication by interpreting and responding to XML. The XML is an extensible markup language and is used for marking the electronic file so as to enable the electronic file to have a structure.
The application server can comprise a Web server, a daoArcIMS application server and an ArcIMS application server, a user request is received by the application server and is sent to the data server side through a protocol, and the data server side generates a response or a command according to the user request and sends the response or the command to the terminal or the controller. The application server may concurrently process multiple user requests to simultaneously process multiple video subscription requests in a cascading conference.
For example, in a multi-party video conference, a conference terminal (application server) is cascaded with a plurality of controllers, and each controller is cascaded with a plurality of processes to construct a multi-party video conference basic architecture.
The plurality of destination terminals respectively carry out video subscription to source terminals controlled by the same processor, the plurality of destination terminals respectively upload video subscription requests to the conference terminal or the application server, and the conference terminal or the application server correspondingly generates a first video subscription instruction according to the video subscription requests and issues the first video subscription instruction to the corresponding controller. And the plurality of controllers generate video stream issuing requests according to the corresponding first video subscription instructions so as to control the corresponding processors to send the video streams, thereby simultaneously completing the video stream issuing of the plurality of video subscriptions.
In some embodiments, the controller may concurrently process a plurality of first video subscription instructions and generate corresponding video stream transmission requests, and the processor transmits the video streams to corresponding destination terminals according to the corresponding video stream transmission requests.
Referring 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 transmission request by the first video subscription instruction, and further includes: step S201, a controller generates a first media sending request according to a first video subscription instruction; step S202, a source processor sends a video stream to a destination processor according to a first media sending request and generates a first media sending response; step S203, the controller generates a first media receiving request according to the first media sending response; step S204, the destination processor receives the video stream according to the first media receiving request.
The controller controls the source processor to send the video stream of the destination terminal to the destination processor by issuing a first media sending request to the source processor. The destination processor receives the video stream from the source process in accordance with the controller first media reception request. The media channel is arranged between the destination processor and the source processor, so that video streaming can be carried out between the destination processor and the source processor.
For example, when a destination terminal sends a video subscription request to a conference terminal, a first video subscription instruction is issued to a controller through the same conference terminal, and the controller respectively generates first media sending requests according to the first video subscription instruction; and the source processor transmits the video stream of the source terminal to the destination processor according to the first media transmission request and generates a first media transmission response.
When the controller receives the first media sending response, the controller generates a corresponding first media receiving request and sends the first media receiving request to the destination processor; when the destination processor receives the first media receiving request, the destination processor starts to receive the corresponding video stream to pre-store the video stream in the designated area.
In some embodiments, an identity check character string corresponding to the destination processor or the destination terminal is set in the first media sending request, so that when the destination terminal has no video subscription right, the source processor is prohibited from sending the video stream to the destination processor.
For example, when the source terminal is a limited terminal and the destination terminal has no corresponding video subscription right, the controller issues the first media sending request to the source processor, and the source processor checks the identity of the destination terminal or the destination processor according to the identity check character string in the first media sending request. If the destination terminal has the video subscription right 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; and if the destination terminal has no video subscription right to the source terminal, the source processor judges that the first media sending request is an invalid request and generates a corresponding subscription response.
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 no subscription right response. And the conference terminal still generates a video subscription response without subscription authority according to the subscription authority response, and transmits the subscription authority response back to the destination terminal so as to remind the destination terminal that the video subscription authority for the source terminal is not available temporarily.
In some embodiments, when the destination terminal receives the no-subscription-permission response, the destination terminal may upload the video subscription permission request to the conference terminal to obtain the video subscription permission corresponding to the source terminal. And after the destination terminal obtains the corresponding video subscription authority, the conference terminal re-issues the first video subscription instruction to the controller so as to complete the video subscription of the destination terminal to the source terminal.
In some embodiments, a terminal permission list is set in the conference terminal, and when the destination terminal performs the video subscription permission on the source terminal, the conference terminal checks the identity check character string in the video subscription request to determine whether the destination terminal has the video subscription permission corresponding to the source terminal. If the destination terminal has the video subscription authority corresponding to the source terminal, the conference terminal generates a first video subscription instruction according to the video subscription request and issues the first video subscription instruction to the corresponding controller; and if the destination terminal does not have the video subscription authority corresponding to the source terminal, the conference terminal generates a no-subscription-authority response according to the video subscription request and transmits the no-subscription-authority response back to the destination terminal.
And the destination terminal acquires the video subscription authority corresponding to the source terminal by uploading the video subscription authority request, and updates the terminal authority list in the conference terminal so as to update the subscription authority information of the destination terminal into the terminal authority list.
Referring 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. Wherein the controller generating a video stream to respond comprises; step S2041, the destination processor generates a first media receiving response according to the first media receiving request; step S2042, the controller generates a video stream sending request according to the first media receiving response; step S2043, the destination processor issues the video stream according to the video stream issuing request.
After the destination processor receives the first media receiving request, the destination processor starts to receive the video stream from the source processor, generates a first media receiving response and uploads the first media receiving response to the controller. The controller generates a video stream sending request according to the first media receiving response and sends the video stream sending request to the target processor, and the target processor sends the video stream of the source terminal to the target terminal according to the video stream sending request.
After the target processor receives the subscribed video stream, the video stream is issued under the control of the video stream issuing request, so that the situation that the target processor does not receive the video stream is avoided, and the target processor sends the video stream to a target terminal to cause occupation of a communication 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. And the controller generates a video stream issuing response according to the first media receiving response by transmitting the first media receiving response back to the controller. And the controller transmits the video stream issuing response to the destination processor, and the destination processor transmits the video stream to the appointed destination terminal according to the video stream issuing response.
Referring to fig. 2, 4-7, in some embodiments, the destination processor is connected to at least two terminals, and only one of the terminals is the destination terminal. Step S2043, the destination processor issues the video stream according to the video stream issue request, further comprising: step S2044, the destination processor issues the video stream to the appointed terminal according to the video stream issuing request; step S2045, the destination processor generates a video stream issuing response according to the video stream issuing request.
And the destination processor issues the video stream to the appointed destination terminal according to the video stream issuing request so as to avoid the video stream from being erroneously issued to other terminals, thereby ensuring the accuracy of information transmission. For example, a marking character string corresponding to the destination terminal is set in the video stream issuing request, and the destination processor selects a terminal to which the video stream is issued according to the marking character string and issues the video stream to the corresponding terminal, so as to complete issuing of the video stream in the video subscription.
For example, an identity check character string is set in the video stream issuing response, and the destination processor issues the video stream to a specified destination terminal according to the identity check character string, so as to prevent the destination processor from issuing the video stream to other terminals except the destination terminal. 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 are occupied.
Referring to fig. 2, 8 and 9, in some embodiments, the controller includes at least a source controller and a destination controller, and the processor includes at least a source processor and a destination processor. The target terminal is controlled by a target processor, and the target processor is controlled by a target controller; the source terminal is controlled by a source processor, and the source processor is controlled by a source controller; the destination controller and the source controller are controlled by the same conference terminal. And cascade control is carried out on the controllers through the same conference terminal, and each controller carries out cascade control on the processors so as to construct a cascade conference communication network.
Step S203, the controller generates a first media sending request according to the first video subscription instruction, including: step S2031, the source controller generates a first media sending request according to the first video subscription instruction and issues the first media sending request to the source processor; step S2032, the source processor transmits the video stream of the source terminal to the destination processor according to the first media sending request; step S2033, the source processor generates a first media sending response according to the first media sending request and transmits the first media sending response back to the source controller. When the source processor starts to send the video stream, the source processor generates a first media sending response according to the first media sending request and transmits the first media sending response back to the source controller.
For example, the destination terminal and the source terminal are respectively in the same cascading conference, and the conference terminal controls the source processor to transmit the video stream to the corresponding destination processor by issuing a first video subscription instruction to the source controller. And after the source processor starts to transmit the video stream, the source processor generates a first media sending response according to the first media sending request and transmits the first media sending response back to the source controller. And returning a media sending response through the corresponding source processor to ensure that the source processor already starts to send the video stream of the source terminal before the destination processor starts to receive the video stream, thereby avoiding the resource occupation of the media channel.
In some embodiments, a media channel is provided between the destination terminal and the source terminal, the destination processor is connected with at least two terminals, the source processor is connected with at least two terminals, and the terminal corresponding to the destination processor and the terminal corresponding to the source processor share the same media channel. And sending a response to the source controller through the return medium so as to facilitate the resource allocation of the media channel and avoid uneven transmission resource allocation of the media channel caused by the transmission of a plurality of video streams in the same media channel.
In some embodiments, one source processor corresponds to multiple source terminals, one destination processor corresponds to multiple destination terminals, and a media channel between a destination terminal and a source terminal is a media multiplexing channel.

The source controller and the target controller are subjected to hierarchical processing through the conference terminal, so that video subscription among different terminals can be carried out simultaneously. For example, by setting up an instruction channel and a media channel, the conference terminal, the source controller, the source processor, the destination controller and the destination processor transmit the request signal and the response signal through the instruction channel, and the source terminal and the destination terminal transmit the video stream through the media channel.
The conference terminal sends the first video subscription instruction to the plurality of source controllers respectively, and different source processors send the first media sending request according to the corresponding source controllers, so that the video subscription among the plurality of terminals can be carried out simultaneously in the cascade conference.
