Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, a flowchart illustrating steps of a video information processing method based on a video network according to an embodiment of the present invention is shown, and the method is applied to a service layer of an operating system of a video network device, and specifically may include the following steps:
in step S101, receiving first video information of a first service protocol uploaded by a protocol layer, where the first video information is sent to the protocol layer by a first service server in a plurality of service servers, and the first service protocol is a service protocol supported by the first service server;
if a certain device supports a certain service protocol, it indicates that the device can identify the service protocol, that is, the device can parse out the content in the information of the service protocol.
In the application, a Service layer is arranged between a protocol layer (VVP) and a Terminal program layer (VVBS) in an operating system of a Video networking device, and the Service layer is used as a middleware between the protocol layer and the Terminal program layer (VVT), so that when information interaction is required between the Terminal program layer and the protocol layer, information is not directly sent to an opposite side, but information required to be sent to the opposite side is forwarded through the Service layer.
For example, when the protocol layer needs to upload information to the terminal program layer, the protocol layer may upload the information to the service layer, and then upload the information to the terminal program layer by the service layer.
Correspondingly, when the terminal program layer needs to issue information to the protocol layer, the terminal program layer may issue the information to the service layer first, and then the service layer issues the information to the protocol layer.
In the application, the video networking device may perform information interaction with the plurality of service servers respectively via the protocol layer of the operating system, when a first service server of the plurality of service servers needs to send first video information of a first service protocol to the video networking device, the first service server may send the first video information of the first service protocol to the protocol layer of the operating system of the video networking device, then the protocol layer receives the first video information of the first service protocol sent by the first service server, the protocol layer uploads the first video information of the first service protocol to the service layer, the service layer receives the first video information of the first service protocol uploaded by the protocol layer, and then step S102 is performed.
In the application, the plurality of service servers include a video network tangula server, a video network streaming media server, a video network storage gateway, a video network protocol server, a video network gateway server, a video network meeting management server and the like.
The first video information includes information for pulling in a video-networking conference, information of a conference video in the video-networking conference, and the like.
In step S102, converting the first video information into second video information of a preset service protocol, where the preset service protocol includes a service protocol supported by a terminal program layer of the operating system;
in the present application, the service layer needs to have a capability of identifying service protocols respectively supported by the plurality of service servers, that is, it needs to have a capability of parsing information of the service protocols respectively supported by the plurality of service servers, and thus, the service layer can parse first video information of the first service protocol. The preset service protocols are less than the number of the service protocols needing to be identified by the service server layer.
Since the service layer needs to have the capability of identifying the service protocols supported by the service servers, the terminal program layer may only have the capability of identifying one service protocol, and does not need to have the capability of identifying the service protocols supported by the service servers.
In order to enable the terminal program layer to identify the content in the first video information, corresponding business processing can be carried out. In this application, the service layer needs to convert the first video information into the second video information of the preset service protocol, where the preset service protocol includes the service protocol supported by the terminal program layer of the operating system, and then step S103 is executed.
In step S103, the second video information is uploaded to the terminal program layer.
In the application, first video information of a first service protocol uploaded by a protocol layer is received, wherein the first video information is sent to the protocol layer by a first service server in a plurality of service servers, and the first service protocol is a service protocol supported by the first service server; converting the first video information into second video information of a preset service protocol, wherein the preset service protocol comprises a service protocol supported by a terminal program layer of an operating system; and uploading the second video information to the terminal program layer.
By the application, the terminal program layer does not need to have the capability of identifying the service protocols respectively supported by the plurality of service servers, but the terminal program layer can identify a small number of service protocols, for example, the terminal program layer can identify a preset number of service protocols, the preset number is less than the number of the service protocols to be identified by the service server layer, and the work of identifying the service protocols respectively supported by the plurality of service servers is delivered to the service layer for execution, namely, compared with the prior art, the application uses the service layer to share part of the work of the terminal program layer, so that computer codes and the like for respectively identifying the plurality of service protocols do not need to be arranged in the terminal program layer, but computer codes for identifying the small number of service protocols can be arranged in the terminal program layer, thereby reducing the redundancy of the terminal program layer, and simplifying the service codes in the terminal program layer, so that the service codes in the terminal program layer are easier to maintain.
By the method and the device, different jobs are processed by different logic layers as much as possible, and further the computer codes in the video networking equipment are separated logically, so that the logic of the computer codes in the video networking equipment is clearer, and technicians can conveniently check and maintain the computer codes.
In an alternative embodiment, the preset service protocol may be a service protocol, and thus, the computer code for identifying a service protocol may be set in the terminal program layer, so that the code redundancy of the terminal program layer may be maximally reduced, the service code in the terminal program layer may be maximally simplified, and further, the service code in the terminal program layer may be easier to maintain.
In one scenario, the video networking device may invoke a video stream from the service server, however, in general, when the video stream is transmitted between the service server and the protocol layer of the operating system of the video networking device, the video stream is often split into a plurality of video frames, then each video frame is transmitted to the other side, the protocol layer may receive each video frame, then each video frame is forwarded to the terminal program layer, and the terminal program layer combines each video frame into a complete video stream according to the sequence therebetween, and then processes the complete video stream.
However, this requires the capability of the terminal program layer to recognize the order between the individual video frames and to combine the first video frames into a complete video stream.
However, if the terminal program layer is required to be able to recognize the sequence between the video frames and to combine the video frames into a complete video stream, the complexity of the terminal program layer increases, for example, computer code for recognizing the sequence between the video frames and combining the video frames into a complete video stream needs to be provided in the terminal program layer, and thus, the code of the terminal program layer is redundant and difficult to maintain.
Therefore, in order to avoid this situation, in the present application, if a plurality of first video frames are included in the first video information and the plurality of first video frames are split from the complete first video stream; in the first video information, the service layer may combine the plurality of first video frames into a complete first video stream, and then convert the first video information into second video information of a preset service protocol.
In the present application, the service layer needs to have the capability of identifying the sequence between the video frames and the capability of combining the video frames into a complete video stream, and the service layer needs to have the capability of identifying the sequence between the video frames and the capability of combining the video frames into a complete video stream, so the terminal program layer may not have the capability of identifying the sequence between the video frames and the capability of combining the video frames into a complete video stream.
Therefore, the work of identifying the sequence among the video frames and the work of combining the video frames into a complete video stream can be carried out by the service layer, and the terminal program layer can obtain the complete video stream without executing redundant work.
Correspondingly, if the video networking equipment needs to issue the third video information to a second service server in the plurality of service servers, because the terminal program layer supports the preset service protocol, the terminal program layer can issue the third video information of the preset service protocol to the service layer, and then the service layer receives the third video information of the preset service protocol issued by the terminal program layer, wherein the destination address of the third video information is the second service server in the plurality of service servers; the third video information can be converted into fourth video information of a second service protocol; the second service protocol comprises a service protocol supported by the second service server; and then, the protocol layer sends the fourth video information to the second service server, and the second service server can analyze the content in the fourth video information because the second service server can support the second service protocol.
The third video information includes an instruction of the video networking remote controller received by the terminal program layer, for example, information for issuing and watching the live video, and the like.
For the service layer, a correspondence between a server identifier of the service server and a protocol content of a service protocol supported by the service server may be stored in the service layer in advance, and each corresponding entry in the correspondence includes the server identifier of the service server and the protocol content of the service protocol supported by the service server.
In this way, when the third video information is converted into the fourth video information of the second service protocol, the server identifier of the second service server can be obtained; then, in the corresponding relation between the server identification of the service server and the protocol content of the service protocol supported by the service server, the protocol content corresponding to the server identification is searched; and modifying the protocol content in the third video information into the searched protocol content.
In the present application, the service layer needs to have the capability of generating information of service protocols supported by the plurality of service servers, respectively, and the service layer needs to have the capability of generating information of service protocols supported by the plurality of service servers, respectively.
According to the method and the device, the terminal program layer does not need to have the capacity of generating the information of the service protocols supported by the plurality of service servers respectively, and the terminal program layer only has the capacity of generating the information of one service protocol, and the work of generating the information of the service protocols supported by the plurality of service servers respectively is delivered to the service layer to be executed.
Further, if the second video information includes the complete second video stream; then, the complete second video stream may be split into a plurality of second video frames in the second video information, and then the third video information may be converted into fourth video information of the second service protocol.
In the application, the service layer needs to have the capability of splitting a complete video stream into a plurality of video frames, and the service layer needs to have the capability of splitting a complete video stream into a plurality of video frames, so the terminal program layer may not have the capability of splitting a complete video stream into a plurality of video frames.
The operation of splitting a complete video stream into a plurality of video frames is not required to be executed by a terminal program layer and can be executed by a service layer, the terminal program layer is not required to split a second video stream, and a protocol layer can obtain a plurality of second video frames included in the second video stream.
Referring to fig. 2, a flowchart illustrating steps of a video information processing method based on a video network according to an embodiment of the present invention is shown, where the method may specifically include the following steps:
in step S201, the protocol layer uploads first video information of a first service protocol to the service server layer; the first video information is sent to a protocol layer by a first service server in the plurality of service servers, and the first service protocol is a service protocol supported by the first service server;
if a certain device supports a certain service protocol, it indicates that the device can identify the service protocol, that is, the device can parse out the content in the information of the service protocol.
In the application, a Service layer is arranged between a protocol layer (VVP) and a Terminal program layer (VVBS) in an operating system of a Video networking device, and the Service layer is used as a middleware between the protocol layer and the Terminal program layer (VVT), so that when information interaction is required between the Terminal program layer and the protocol layer, information is not directly sent to an opposite side, but information required to be sent to the opposite side is forwarded through the Service layer.
For example, when the protocol layer needs to upload information to the terminal program layer, the protocol layer may upload the information to the service layer, and then upload the information to the terminal program layer by the service layer.
Correspondingly, when the terminal program layer needs to issue information to the protocol layer, the terminal program layer may issue the information to the service layer first, and then the service layer issues the information to the protocol layer.
In the application, the video networking equipment can perform information interaction with the plurality of service servers respectively through the protocol layer of the operating system, when a first service server in the plurality of service servers needs to send first video information of a first service protocol to the video networking equipment, the first service server can send the first video information of the first service protocol to the protocol layer in the operating system of the video networking equipment, then the protocol layer receives the first video information of the first service protocol sent by the first service server, and the protocol layer uploads the first video information of the first service protocol to the service layer.
In the application, the plurality of service servers include a video network tangula server, a video network streaming media server, a video network storage gateway, a video network protocol server, a video network gateway server, a video network meeting management server and the like.
The first video information includes information for pulling in a video-networking conference, information of a conference video in the video-networking conference, and the like.
In step S202, the service server layer receives first video information of a first service protocol uploaded by the protocol layer;
in step S203, the service server layer converts the first video information into second video information of a preset service protocol, where the preset service protocol includes a service protocol supported by a terminal program layer of the operating system;
in the present application, the service layer needs to have a capability of identifying service protocols respectively supported by the plurality of service servers, that is, it needs to have a capability of parsing information of the service protocols respectively supported by the plurality of service servers, and thus, the service layer can parse first video information of the first service protocol. The preset service protocols are less than the number of the service protocols needing to be identified by the service server layer.
Since the service layer needs to have the capability of identifying the service protocols supported by the service servers, the terminal program layer may only have the capability of identifying one service protocol, and does not need to have the capability of identifying the service protocols supported by the service servers.
In order to enable the terminal program layer to identify the content in the first video information, corresponding business processing can be carried out. In this application, the service layer needs to convert the first video information into the second video information of the preset service protocol, where the preset service protocol includes a service protocol supported by a terminal program layer of the operating system, and then step S204 is executed.
In one scenario, the video networking device may invoke a video stream from the service server, however, in general, when the video stream is transmitted between the service server and the protocol layer of the operating system of the video networking device, the video stream is often split into a plurality of video frames, then each video frame is transmitted to the other side, the protocol layer may receive each video frame, then each video frame is forwarded to the terminal program layer, and the terminal program layer combines each video frame into a complete video stream according to the sequence therebetween, and then processes the complete video stream.
However, this requires the capability of the terminal program layer to recognize the order between the individual video frames and to combine the first video frames into a complete video stream.
However, if the terminal program layer is required to be able to recognize the sequence between the video frames and to combine the video frames into a complete video stream, the complexity of the terminal program layer increases, for example, computer code for recognizing the sequence between the video frames and combining the video frames into a complete video stream needs to be provided in the terminal program layer, and thus, the code of the terminal program layer is redundant and difficult to maintain.
Therefore, in order to avoid this situation, in the present application, if a plurality of first video frames are included in the first video information and the plurality of first video frames are split from the complete first video stream; in the first video information, the service layer may combine the plurality of first video frames into a complete first video stream, and then convert the first video information into second video information of a preset service protocol.
In the present application, the service layer needs to have the capability of identifying the sequence between the video frames and the capability of combining the video frames into a complete video stream, and the service layer needs to have the capability of identifying the sequence between the video frames and the capability of combining the video frames into a complete video stream, so the terminal program layer may not have the capability of identifying the sequence between the video frames and the capability of combining the video frames into a complete video stream.
Therefore, the work of identifying the sequence among the video frames and the work of combining the video frames into a complete video stream can be carried out by the service layer, and the terminal program layer can obtain the complete video stream without executing redundant work.
In step S204, the service server layer uploads the second video information to the terminal program layer;
in step S205, the terminal program layer receives the second video information.

By the method and the device, different jobs are processed by different logic layers as much as possible, and further the computer codes in the video networking equipment are separated logically, so that the logic of the computer codes in the video networking equipment is clearer, and technicians can conveniently check and maintain the computer codes.
In an alternative embodiment, the preset service protocol may be a service protocol, and thus, the computer code for identifying a service protocol may be set in the terminal program layer, so that the code redundancy of the terminal program layer may be maximally reduced, the service code in the terminal program layer may be maximally simplified, and further, the service code in the terminal program layer may be easier to maintain.
Accordingly, if the video networking device needs to issue the third video information to the second service server in the plurality of service servers, as shown in fig. 3, the method further includes:

As shown in the following table, the data packet of the access network mainly includes the following parts:
DA SA Reserved Payload CRC
wherein:

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.

DA SA Reserved label (R) Payload CRC
Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC.
