2. Video networking 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 bytes, payload (pdu), CRC.
As shown in table 1, the data packet of the access network mainly includes the following parts:
| DA | SA | Reserved | Payload | CRC |
TABLE 1
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 different types of datagrams, and is 64 bytes if the datagram is various types of protocol packets, and is 32+1024 or 1056 bytes if the datagram is a unicast packet, of course, the length is not limited to the above 2 types;
the CRC consists of 4 bytes and is calculated in accordance with 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 0x 0001. 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 table 2, the data packet of the metropolitan area network mainly includes the following parts:
| DA | SA | Reserved | label (R) | Payload | CRC |
TABLE 2
Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: 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.
Based on the characteristics of video networking, the data playing method is applied to a video conference system of the video networking, wherein the video conference system comprises a chairman terminal, member terminals and a server; before a video conference is carried out, a terminal device for hosting the conference can be selected, and the terminal device is determined as a chairman terminal; the chairman terminal sends the information of the terminals participating in the video conference to the server; the server sends the video conference invitation to each terminal participating in the video conference, and after the terminal receives the video conference invitation, the terminal can join in the video conference, and then the terminal can be determined as a member terminal. And after all the member terminals join the video conference, the video conference can be started. In the process of video conference, the chairman terminal can send various control instructions to each member terminal through the server.

In addition, it is needless to say that the code library may also be embedded into a system code of the chairman terminal operating system, where the embodiment of the present invention does not limit the type of the operating system, such as an android system, a Linux system, and the like.
Step 502, the member terminal obtains a target instruction from the server, wherein the target instruction is sent to the server by the chairman terminal.
In the process of the video conference, when the number of the playing windows displayed in the member terminal needs to be changed, the operation can be performed on the chairman terminal, namely, a user selects the number of the playing windows needing to be displayed, the chairman terminal generates a target instruction according to the selected number, and the target instruction is used for changing the number of the playing windows displayed by the member terminal. And then the chairman terminal sends the target instruction to a server, the server forwards the target instruction to a corresponding member terminal, and the member terminal can obtain the target instruction from the server.
Step 503, closing the current playing window playing the multimedia data, and creating a corresponding number of target playing windows according to the target instruction.
In the video conference process, the member terminal can play multimedia data through the playing window, after receiving a target instruction, the member terminal can close the current playing window playing the multimedia data and create a target playing window corresponding to the data according to the target instruction; wherein the multimedia data includes video data and audio data. For example, the number of current playing windows in which the member terminal is currently playing the multimedia data is 3, and after receiving the target instructions, the number corresponding to the target instructions is 4, the 3 windows in which the multimedia data is being played are closed, and then 4 target playing windows are created.
In the embodiment of the present invention, when the number of the target playing windows is more than one, different multimedia data that can be played by different target playing windows may be different, where the different multimedia data refers to different terminals to which the multimedia data belong, such as multimedia data corresponding to a chairman terminal, multimedia data corresponding to a member terminal, multimedia data corresponding to a conference speaker terminal, and the like, and the multimedia data played by each target playing window may be set as required; of course, when the number of the target playing windows is one, the multimedia data played correspondingly can be set according to the requirement. Therefore, after the target playing windows are created, the code base can be called to obtain the multimedia data corresponding to each target playing window, and the obtained multimedia data are decoded; compared with the prior art, the code library has higher efficiency of acquiring and processing the multimedia data than the system code, thereby improving the fluency of playing the multimedia data.
And 505, calling a system code to play the multimedia data through a corresponding target playing window.
And after the code base successfully decodes the acquired multimedia data, the system code can be called to play the decoded multimedia data through the corresponding target playing window.
In addition, the chairman terminal can close the current playing window while sending the target instruction, create a corresponding target playing window according to the number of the displayed playing windows selected by the user, and play the corresponding video data through the target playing window; of course, the chairman terminal may not change the current playing state.
The method comprises the steps that a code base is embedded into a system code of a member terminal operating system in advance, and further a member terminal closes a current playing window playing multimedia data after acquiring a target instruction from a server, and creates a corresponding number of target playing windows according to the target instruction; then, multimedia data corresponding to the target playing window is obtained by calling a code library; then, the system code is called to play the acquired multimedia data through the target playing window; therefore, the member terminals can display the corresponding number of playing windows and play the corresponding multimedia data according to the user requirements, so that the user requirements are met, and the user experience is improved.
In another embodiment of the present invention, the creation of the target playing window and the acquisition of the multimedia data corresponding to each target window are explained in detail.
Referring to fig. 6, a flowchart illustrating steps of another embodiment of a data playing method according to the present invention is shown, which may specifically include the following steps:
In the embodiment of the invention, the code base can be embedded into the system codes of the operating systems of several member terminals of the video conference system in advance; the code base can also be embedded in the system codes of all member terminal operating systems in the video conference system; the number of the member terminals embedded into the code base can be set according to requirements.
Step 602, the member terminal obtains a target instruction from the server, wherein the target instruction is sent to the server by the chairman terminal.
In the embodiment of the invention, when a user wants to change the number of the playing windows displayed by the member terminals, the target instruction can be sent to the server through the chairman terminal, and then the server sends the target instruction to the corresponding member terminals; wherein the target instruction comprises: the target instruction comprises quantity information and terminal information of a terminal to which the multimedia data belongs, such as an ID (identity) of terminal equipment, and the terminal comprises a chairman terminal and a member terminal in the video conference system. In the embodiment of the present invention, the multimedia data corresponding to each terminal includes: the terminal comprises video data acquired by image acquisition equipment of the terminal, audio data recorded by terminal voice acquisition equipment, and screen recording data obtained by recording a terminal screen by a screen recording application of the terminal, wherein correspondingly, the playing window comprises a video playing window and an audio playing window, the video playing window is used for playing the video data and the screen recording data, and the audio playing window is used for playing the audio data.
After receiving the target instruction, the member terminal may close the current playing window in which the multimedia data is being played, which is specifically as follows:
And step 604, calling the system code to remove the current playing control from the current interface.
The embodiment of the invention creates a playing window through a playing control and plays corresponding multimedia data through the playing window; the playing control is created and removed by calling a system code, and the multimedia data is acquired by calling a code library; therefore, when the current playing window is closed, the code library can be called to stop obtaining the media data corresponding to the current playing window, then the system code is called to remove all current playing controls in the interface from the current interface, and the current playing window is closed. And the current playing control is used for creating the current playing window and playing the multimedia data.
After the current playing window is closed, a corresponding number of target playing windows can be created according to the target instruction, which is as follows:
step 605, invoking the system code to create a corresponding number of target playing controls according to the number information, where the number is at least one.
In the embodiment of the present invention, the quantity information in the target instruction includes the quantity of the playing windows that need to be created, where the quantity is at least one; when a new playing window is created, the system code can be called to create a corresponding number of playing controls according to the number information, and the created new playing controls are determined as target playing controls; after the target playing control is created, the corresponding target window is created. In order to improve user experience, each target playing window can play different multimedia data, so that after the target playing control is created, terminal information of a terminal to which the multimedia data belongs can be obtained from a target instruction, and which target playing window is determined according to requirements to play the multimedia data corresponding to which terminal; and then adding corresponding terminal information for the target playing control.
In another embodiment of the present invention, the multimedia data corresponding to the target playing control is obtained from a code library, so that after the target playing control is created, the code library can be called to obtain the corresponding multimedia data, which is specifically as follows:
and step 607, calling a code library to acquire the terminal information corresponding to the target playing control.
