In other embodiments of the present application, the video and audio signal scheduling system may also be composed of more or fewer components, which is not limited herein.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating steps of a video/audio signal scheduling method according to an embodiment of the present disclosure, where the video/audio signal scheduling method can be implemented by the matrix controller 10 in fig. 1 as an execution main body. The video and audio signal scheduling method is described in detail below.
Step S201, acquiring a plurality of video and audio signals to be processed, and obtaining a video and audio group signal according to an overlapping relationship between the plurality of video and audio signals to be processed.
The audio-video group signal is a full-scale signal.
In step S202, a first leaf node 301 and a second leaf node 302 are determined from the plurality of leaf nodes 30 according to the audio/video set signal.
The first leaf node 301 is a video/audio group signal inflow node, and the second leaf node 302 is a video/audio group signal outflow node.
In step S203, a first signal stream table is established on the first leaf node 301, so that the video/audio group signal is input into the first leaf node 301.
In step S204, a second signal stream table is established on the first leaf node 301 and the spine node 20, so that the audio/video group signal is forwarded from the first leaf node 301 to the spine node 20.
In step S205, a third signal stream table is established on the ridge node 20 and the second leaf node 302, so that the audio-video group signal is forwarded from the ridge node 20 to the second leaf node 302.
In step S206, a fourth signal stream table is established on the second blade node 302 so that the audio/video set signal is output from the second blade node 302.
In the embodiment of the present application, the Spine node 20 included in the video/audio signal scheduling system is Spine in a Spine network architecture (Spine-Leaf), the Leaf node 30 is Leaf in the Spine network architecture, a first Leaf node 301 may be determined according to a video/audio group signal, and the first Leaf node 301 serves as an edge device of the video/audio signal scheduling system and is responsible for receiving an externally-sent video/audio signal into the video/audio signal scheduling system. After the second leaf node 302 is determined from the plurality of leaf nodes 30 according to the audio group signal, signal flow tables may be established on the related leaf nodes 30 and spine nodes 20 by the matrix controller 10, so that each leaf node 30 and spine node 20 can process the video and audio signals according to each of all the signal flow tables, where the number of the second leaf nodes 302 may be one or more, and is not limited herein.
It should be understood that in the embodiment of the present application, the number of the to-be-processed video and audio signals may be the number of the to-be-processed video and audio signals that need to be forwarded to the media devices, for example, the video and audio signal scheduling system needs to forward the signals to the devices such as the switchboards, the listing servers, and the monitors, and then there may be three to-be-processed video and audio signals for the devices such as the switchboards, the listing servers, and the monitors, and each externally-input to-be-processed video and audio signal may include a video stream, an audio stream, and auxiliary data. The video and audio group signal is a full-scale signal, and the video and audio signal scheduling system will make all the video and audio signals to be processed into a full-scale signal, i.e. the video and audio group signal in the present scheme, according to the overlapping relationship of the signal stream groups and the distribution of the output leaf nodes 30. For example, there are two audiovisual signals to be processed, audiovisual signal 1 (video 1: 228.0.0.1, audio 1: 229.0.0.1, auxiliary data 1: 230.0.0.1), output Leaf2 and audiovisual signal 2 (video 1: 228.0.0.1, audio 1: 229.0.0.1, audio 2: 229.0.0.2, auxiliary data 1: 230.0.0.1), output Leaf 3. As described above, analysis can be performed according to the multicast address, and the video stream and the auxiliary stream are found to be duplicated, while the output Leaf node 30 of the video and audio signals to be processed can be considered, and it can be known that the Leaf nodes respectively represented by Leaf2 and Leaf3 are output, and a full signal including at least the following information can be obtained: (video 1: 228.0.0.1, audio 1: 229.0.0.2, audio 2: 229.0.0.2, auxiliary data 1: 230.0.0.1), Leaf2, Leaf 3. I.e. the full signal remains only one copy of the repeated data.
Then, the video and audio group signal may be input into the video and audio signal scheduling system through the first leaf node 301, and the signal flow tables established on the related leaf node 30 and the ridge node 20 are used to correspondingly forward the full-volume signal (i.e., the video and audio group signal), so that each signal included in the full-volume signal is forwarded to the corresponding portion, and the repeated signal between the related leaf node 30 and the ridge node 20 can be forwarded only by sending once, that is, only one bandwidth is occupied, thereby solving the problem that a plurality of signals need to establish flow tables respectively, and further, a large amount of bandwidth is occupied.
In one possible embodiment, please refer to fig. 3 in combination, the video/audio signal scheduling system further includes a media controller 40, wherein the media controller 40 is connected to the matrix controller 10 in a communication manner; the aforementioned step S202 may be implemented by performing the following detailed steps.

The input signal stream group may refer to a signal content that needs to be forwarded and scheduled by the video and audio signal scheduling system, and specifically may include a video signal, an audio signal, and an auxiliary signal. The input device identifier may be a device identifier corresponding to a first leaf node 301 of the video/audio group signal input video/audio scheduling system, or may be a device identifier of an edge device communicatively connected to the first leaf node 301 for receiving the video/audio group signal, which is not limited herein. The input port identifier may refer to a port identifier corresponding to a port located on the first leaf node 301 corresponding to the input device identifier and used for receiving the input signal stream group, and the output device identifier may refer to a device identifier of a second leaf node 302 or a media device corresponding to the second leaf node 302, which is required to output the video signal, the audio signal, and the auxiliary signal in the signal stream group, in the plurality of leaf nodes 30, which is not limited herein. The output device identification may refer to a port identification corresponding to a port located on the second blade node 302 where the video signal, the audio signal and the auxiliary signal in the set of input signal streams need to be output.
In order to more clearly describe the scheme provided by the embodiments of the present application, the foregoing embodiments are exemplified below. In this embodiment, the media controller 40 may issue entries (i.e. the entries corresponding to the video and audio group signals are defined): matrix signal 1{ video, audio 1, auxiliary data }, in Leaf1+ in port 1, out Leaf2+ out port 1 to matrix controller 10, matrix controller 10 determining a first Leaf node 301 from in Leaf1 (input device identification), and further determining a signal corresponding to input matrix signal 1{ video, audio 1, auxiliary data } at first Leaf node 301 from port 1 (input port identification), it should be understood that, in this case, only one set of signals in the signal stream group, namely, a video-audio signal corresponding to matrix signal 1, and then determining a second Leaf node 302 from a plurality of Leaf nodes 30 according to the output device identification, and further determining a port for outputting a signal corresponding to matrix signal 1 at second Leaf node 302 according to out port 1, up to which matrix controller 10 can create a signal stream table at the ports involved at spine node 20 and Leaf node 30 in a video-audio scheduling system constructed based on a switching matrix, to implement matching and inputting the signal corresponding to the matrix signal 1 to the port corresponding to the ingress port 1 on the first Leaf node 301 through the first signal flow table (including at least the matrix signal 1, ingress Leaf1+ ingress port 1 and egress Leaf2+ egress port 1), and forwarding the signal corresponding to the matrix signal 1 from the first Leaf node 301 to the spine node 20 through the second signal flow table (including at least the matrix signal 1, egress Leaf2+ egress port 1), after the spine node 20 receives the matrix signal 1, a signal corresponding to the matrix signal 1 may be forwarded to the second Leaf node 302 according to a third signal flow table (including at least the matrix signal 1, the outgoing port 2+ the outgoing port 1) established between the second Leaf node 302, and after receiving the signal corresponding to the matrix signal 1, a signal corresponding to the matrix signal 1 may be output from the output port 1 on the second leaf node 302 according to the fourth signal flow table (including at least the matrix signal 1 and the output port 1). It should be understood that in the embodiment of the present application, the input signal stream group may include more audio and video signals besides the signal corresponding to the matrix signal 1, and accordingly, the input device identifier, the input port identifier, the output device identifier, and the output port identifier corresponding to other matrix signals may be defined.
In a possible implementation manner, the foregoing step S204 may be implemented by the following steps.
In sub-step S204-1, in case there is a free physical link between the first leaf node 301 and the spine node 20, a second signal flow table is established based on the free physical link, so that the audio and video group signals are forwarded from the first leaf node 301 to the spine node 20.

In addition, the connection mode between the first leaf node 301 and the second leaf node 302 and the spine node 20 may be called according to a preset planning policy, for example, priority ranking may be performed on each task, even if there is no idle physical link between the first leaf node 301 and the spine node 20, since the currently processed task level is high, tasks with low task levels may be suspended, so as to provide an idle physical link to enable the first leaf node 301 and the spine node 20 to perform signal forwarding of the current task.
In a possible implementation, the foregoing step S202 may further include the following implementation.
