Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description thereof.
The invention is applied to the video networking conference, improves the video networking scheduling software, can automatically switch speakers in the video networking conference, and automatically removes the speakers after the speakers finish speaking, enriches the speaking forms of the video networking conference, and can improve the efficiency of the video networking conference.
Referring to fig. 1, a flowchart illustrating steps of a method for handing over an originating terminal according to an embodiment of the present invention is shown, where the method may be applied to a video network, and specifically includes the following steps:
In the embodiment of the present invention, the video network terminal refers to a terminal accessing the video network, and the video network terminal may be a mobile terminal accessing the video network, such as a mobile phone, a tablet computer, and other mobile electronic devices. The terminal of the video network may also be a PC (Personal Computer) terminal accessing the video network, such as an electronic device like a desktop Computer and a notebook Computer. Specifically, the method and the device may be determined according to business requirements, and the embodiment of the present invention is not limited in this regard.
In the process of developing the video networking conference, the video networking terminal can send a speaking request to the video networking scheduling software and actively apply for speaking. Specifically, each terminal of the video network has a microphone, and when the terminal of the video network detects that the corresponding microphone has a sound signal, the terminal of the video network sends a speaking request to the scheduling software of the video network to actively apply for speaking.
In practical application, a user can open the video network scheduling software, open the free speaker function corresponding to the video network scheduling software by opening the free speaker function button of the video network scheduling software, and receive a speech request sent by a video network terminal in real time through the video network scheduling software.
After receiving the origination request sent by the terminal of the video network, step 502 is performed.
The video network scheduling software is provided with a speaking zone, the speaking zone may include at least one available terminal access interface, and in general, five available terminal access interfaces may be provided in the speaking zone.
After receiving a speaking request sent by a video network terminal, video network scheduling software determines whether an available terminal access interface exists in a speaking zone in the video network scheduling software.
In some examples, when multiple conference sites perform a racing of the video network conference and the speaking zone includes five available terminal access interfaces, but three video network terminals have access to the speaking zone, so there are two available terminal access interfaces in the speaking zone, in this case, it can be determined that there are available terminal access interfaces in the speaking zone.
In some examples, when multiple conference sites perform a racing of the video network conference and five available access interfaces of the terminals are included in the speaking zone, but five video network terminals have access to the speaking zone, so that all the available access interfaces of the terminals in the speaking zone are occupied, in this case, it can be determined that no available access interfaces of the terminals exist in the speaking zone.
In step 503, when there is an available terminal access interface in the speaking zone, the terminal of the video network is accessed to the available terminal access interface in the speaking zone.
In the embodiment of the present invention, when there is an available terminal access interface in a speaking area, a video network terminal may be accessed to an available terminal access interface in the speaking area, and specifically, the following two situations may be adopted:
1. and when only one available terminal access interface exists in the speaking zone, accessing the video network terminal to the one available terminal access interface.
2. And when at least two available terminal access interfaces exist in the speaking zone, accessing the video network terminal to one available terminal access interface randomly selected from the at least two available terminal access interfaces.
When a plurality of video network terminals send speaking requests to the video network scheduling software, the video network terminals can be sequenced according to the time sequence for sending the speaking requests, and the video network terminals can be sequentially accessed to available terminal access interfaces existing in the speaking area according to the time sequence. For example, the multiple video network terminals are terminal 1, terminal 2, and terminal 3, only one available terminal access interface remains in the speaking zone, and the times when the three video network terminals send speaking requests sequentially are: terminal 2, terminal 1 and terminal 3, then terminal 2 is first accessed to the remaining one available terminal access interface, and when there is a next available terminal access interface in the speech area, terminal 1 is accessed to the next available terminal access interface.
Of course, according to the priorities of multiple video network terminals, a video network terminal with a higher priority may be selected to access the available terminal access interface, and after the video network terminal with a higher priority completes speaking, a video network terminal with a lower priority may be accessed to access the available terminal access interface. For example, the plurality of video network terminals are terminal 1, terminal 2 and terminal 3, only one available terminal access interface remains in the speaking zone, and the priorities of the three video network terminals are: terminal 2, terminal 1 and terminal 3, then terminal 2 is first accessed to the remaining one available terminal access interface, and when there is a next available terminal access interface in the speech area, terminal 1 is accessed to the next available terminal access interface.
In the embodiment of the invention, the video networking scheduling software receives the speaking request sent by the video networking terminal in the developing process of the video networking conference, further determines whether an available terminal access interface exists in a speaking area corresponding to the video networking conference, and accesses the video networking terminal to the available terminal access interface in the speaking area when the available terminal access interface exists in the speaking area, so that the speaking video networking terminal can be accurately and reliably switched directly through the video networking scheduling software, the speaking scene of the video networking conference is enriched, the capture of video or conference site pictures by relying on human eyes is avoided, the carrying efficiency of the video networking conference is improved, the user experience is improved, and the dependence on conference control personnel is relieved.
Referring to fig. 2, a flowchart illustrating steps of a method for switching an originating terminal according to a second embodiment of the present invention is shown, where the method may be applied to a video network, and specifically may include the following steps:
In the process of developing the video networking conference, the video networking terminal can send a speaking request to the video networking scheduling software and actively apply for speaking. Specifically, each terminal of the video network has a microphone, and when the terminal of the video network detects that the corresponding microphone has a sound signal, the terminal of the video network sends a speaking request to the scheduling software of the video network to actively apply for speaking.
In practical application, a user can open the video network scheduling software, open the free speaker function corresponding to the video network scheduling software by opening the free speaker function button of the video network scheduling software, and receive a speech request sent by a video network terminal in real time through the video network scheduling software.
After receiving the talk request sent by the terminal of the video network, step 602 is performed.
The video network scheduling software is provided with a speaking zone, the speaking zone may include at least one available terminal access interface, and in general, five available terminal access interfaces may be provided in the speaking zone.
After receiving a speaking request sent by a video network terminal, video network scheduling software determines whether an available terminal access interface exists in a speaking zone in the video network scheduling software.
In some examples, when multiple conference sites perform a racing of the video network conference and the speaking zone includes five available terminal access interfaces, but three video network terminals have access to the speaking zone, so there are two available terminal access interfaces in the speaking zone, in this case, it can be determined that there are available terminal access interfaces in the speaking zone.
In some examples, when multiple conference sites perform a racing of the video network conference and five available access interfaces of the terminals are included in the speaking zone, but five video network terminals have access to the speaking zone, so that all the available access interfaces of the terminals in the speaking zone are occupied, in this case, it can be determined that no available access interfaces of the terminals exist in the speaking zone.
In practical application, when a plurality of conference places carry out a free speaking link in a video networking conference and five available terminal access interfaces are included in a speaking zone, but five video networking terminals have been accessed at present, so that all the available terminal access interfaces in the speaking zone are occupied, in this case, it can be determined that no available terminal access interface exists in the speaking zone, and then video networking scheduling software generates an access failure message.
And step 604, sending the access failure message to the video network terminal.
After the video network terminal receives the access failure message, the video network terminal stops detecting the sound signal of the corresponding microphone, so that the running load of the video network conference in progress can be reduced, and the smoothness of the video network conference in progress is improved.
Wherein, the step 605 may include:
sub-step 6051 of switching the terminal of the video network to one available terminal access interface when there is only one available terminal access interface in the talk zone.
When a plurality of meeting places carry out a racing link in a video networking meeting and a speaking area contains five available terminal access interfaces, but four video networking terminals are accessed at present, so that one available terminal access interface is also arranged in the speaking area, and under the condition, the video networking terminal can be accessed to the available terminal access interface.
Sub-step 6052, when there are at least two available terminal access interfaces in the speaking zone, the video network terminal is accessed to one available terminal access interface randomly selected from the at least two available terminal access interfaces.
For example, when a plurality of conference sites perform a racing to answer in a video network conference and a speaking zone includes five available terminal access interfaces, but three video network terminals have been accessed at present, and therefore two available terminal access interfaces are still in the speaking zone, in this case, the video network terminal may be accessed to one available terminal access interface randomly selected from at least two available terminal access interfaces.
When a plurality of video network terminals send speaking requests to the video network scheduling software, the video network terminals can be sequenced according to the time sequence for sending the speaking requests, and the video network terminals can be sequentially accessed to available terminal access interfaces existing in the speaking area according to the time sequence. For example, the multiple video network terminals are terminal 1, terminal 2, and terminal 3, only one available terminal access interface remains in the speaking zone, and the times when the three video network terminals send speaking requests sequentially are: terminal 2, terminal 1 and terminal 3, then, first, terminal 2 is accessed to the remaining one available terminal access interface, and when there is a next available terminal access interface in the speech area, terminal 1 is accessed to the next available terminal access interface.
Of course, according to the priorities of multiple video network terminals, a video network terminal with a higher priority may be selected to access the available terminal access interface, and after the video network terminal with a higher priority completes speaking, a video network terminal with a lower priority may be accessed to access the available terminal access interface. For example, the plurality of video network terminals are terminal 1, terminal 2 and terminal 3, only one available terminal access interface remains in the speaking zone, and the priorities of the three video network terminals are: terminal 2, terminal 1 and terminal 3, then, first, terminal 2 is accessed to the remaining one available terminal access interface, and when there is a next available terminal access interface in the speech area, terminal 1 is accessed to the next available terminal access interface.
And 606, sending a stream regulating instruction to the video network server, and detecting the video network terminal speaking according to the stream regulating instruction by the video network server.
The video network scheduling software can send a stream adjusting instruction to the video network server, the video network server detects the video network terminal which speaks after receiving the stream adjusting instruction, and when a sound signal is detected, an audio stream corresponding to the sound signal is downloaded to complete the scheduling of the video network scheduling software on the audio stream of the video network terminal which speaks.
And step 607, in the speaking process of the terminal of the video network, monitoring the speaking ending instruction sent by the terminal of the video network.
In the speaking process of the video network terminal, the video network scheduling software can detect whether a sound signal exists in the video network terminal in real time, when the video network terminal does not detect the sound signal in monitoring for a time period longer than a preset time period, the video network terminal indicates that the speaking of the video network terminal is finished, and at the moment, the video network terminal can send a speaking finishing instruction to the video network scheduling software.
The preset time length may be three seconds, five seconds, or ten seconds, which is not specifically limited in this embodiment of the present invention and may be adjusted according to a specific application scenario.
And when the video network scheduling software receives a speaking ending instruction sent by the video network terminal, the video network scheduling software removes the video network terminal which finishes speaking from the speaking zone. At this time, the video network terminal with the front time can be accessed into the speaking zone according to the time sequence of sending the speaking request. Or selecting the video network terminal with higher priority to be accessed into the speaking zone according to the priorities of a plurality of video network terminals.
In the embodiment of the invention, video networking scheduling software receives a speaking request sent by a video networking terminal in the development process of a video networking conference, further determines whether an available terminal access interface exists in a speaking zone corresponding to the video networking conference, generates an access failure message when the available terminal access interface does not exist in the speaking zone, sends the access failure message to the video networking terminal, accesses the video networking terminal to the available terminal access interface in the speaking zone when the available terminal access interface exists in the speaking zone, sends a stream regulating instruction to a video networking server, detects the video networking terminal speaking according to the stream regulating instruction by the video networking server, monitors a speaking ending instruction sent by the video networking terminal in the speaking process of the video networking terminal, and removes the video networking terminal from the speaking zone when the speaking ending instruction is received, so that the video networking terminal can be accurately and reliably switched by the video networking scheduling software directly, enriches a speaking scene of the video networking conference, avoids the dependence on the capture of a video or conference scene by human eyes, improves the networking efficiency of a video networking conference user, and improves the user experience of the video networking.

As shown in fig. 4, the video network is divided into an access network and a metropolitan network.
The devices of the access network part can be mainly classified into 3 types: node server, access switch, terminal (including various set-top boxes, coding boards, memories, etc.). The node server is connected to an access switch, which may be connected to a plurality of terminals and may be connected to an ethernet network.
The node server is a node which plays a centralized control function in the access network and can control the access switch and the terminal. The node server may be directly connected to the access switch or may be directly connected to the terminal.
Similarly, devices of the metropolitan network portion may also be classified into 3 types: a metropolitan area server, a node switch and a node server. The metro server is connected to a node switch, which may be connected to a plurality of node servers.
The node server is a node server of the access network part, namely the node server belongs to both the access network part and the metropolitan area network part.
The metropolitan area server is a node which plays a centralized control function in the metropolitan area network and can control a node switch and a node server. The metropolitan area server can be directly connected with the node switch and can also be directly connected with the node server.
Therefore, the whole video network is a network structure with layered centralized control, and the network controlled by the node server and the metropolitan area server can be in various structures such as tree, star and ring.

2. Vission networking data packet definition
2.1 Access network packet definition
The data packet of the access network mainly comprises the following parts: destination Address (DA), source Address (SA), reserved byte, payload (PDU), CRC.
As shown in the following table, the data packet of the access network mainly includes the following parts:
| DA | SA | Reserved | Payload | CRC |
wherein:
the Destination Address (DA) is composed of 8 bytes (byte), the first byte represents the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are 256 possibilities at most, the second byte to the sixth byte are metropolitan area network addresses, and the seventh byte and the eighth byte are access network addresses;
the Source Address (SA) is also composed of 8 bytes (byte), defined as the same as the Destination Address (DA);
the reserved byte consists of 2 bytes;
the payload part has different lengths according to the types of different datagrams, 64 bytes if various protocol packets, 32+1024=1056 bytes if single-multicast data packets, and certainly not limited to the above 2 types;
the CRC consists of 4 bytes and its calculation method follows the standard ethernet CRC algorithm.
2.2 metropolitan area network packet definition
The topology of a metropolitan area network is a graph and there may be 2, or even more than 2, connections between two devices, i.e., there may be more than 2 connections between a node switch and a node server, a node switch and a node switch, and a node switch and a node server. However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.
In this specification, the definition of the Label is similar to that of the Label of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between the device a and the device B, there are 2 labels for the packet from the device a to the device B, and 2 labels for the packet from the device B to the device a. The label is classified into an incoming label and an outgoing label, and assuming that the label (incoming label) of the packet entering the device a is 0x0000, the label (outgoing label) of the packet leaving the device a may become 0x0001. The network access process of the metro network is a network access process under centralized control, that is, address allocation and label allocation of the metro network are both dominated by the metro server, and the node switch and the node server are both passively executed, which is different from label allocation of MPLS, and label allocation of MPLS is a result of mutual negotiation between the switch and the server.
As shown in the following table, the data packet of the metro network mainly includes the following parts:
| DA | SA | Reserved | label (R) | Payload | CRC |
Namely Destination Address (DA), source Address (SA), reserved byte (Reserved), tag, payload (PDU), CRC. The format of the tag may be defined as follows: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.
