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 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 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 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 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.
Referring to fig. 5, a flowchart illustrating steps of an embodiment of a picture transmission method according to the present invention is shown, where the method may be applied in a video network, and the method may specifically include the following steps:
step 501, the video network server obtains a plurality of picture resources and creates a container control for each picture resource;
in practice, sometimes, a picture resource needs to be converted into a video stream to be transmitted in a video stream mode, and an original mode of converting the picture resource into the video stream to be transmitted needs to configure a display control in hardware configuration of a server, display the picture resource in the display control, capture a resource picture presented in the display control, and convert the resource picture into the video stream to be transmitted. However, this method takes too much time to transmit the image resource.
Therefore, in the embodiment of the present invention, a virtual container control can be created to carry the resource picture.
When a plurality of picture resources need to be transmitted in a video stream, the plurality of picture resources to be transmitted can be acquired first, and a corresponding container control is created for each picture resource.
In the embodiment of the present invention, acquiring a plurality of picture resources may include the following sub-steps:
substep S51, the video network server receiving the acquisition request; the acquisition request comprises a resource ID;
in practice, the resource in the server has its corresponding resource ID, so that the server is searched for the corresponding resource by the resource ID. Therefore, when acquiring the required picture resources, the user of the invention can input one or more resource IDs corresponding to one or more picture resources on the input interface of the client and trigger the retrieval operation.
And a substep S52, the video network server acquires the corresponding picture resource according to the resource ID.
In a specific implementation, when the server receives the retrieval command, the picture resource matching the resource ID may be retrieved in the database.
In this embodiment of the present invention, the creating, by the video network server, a container control for each picture resource may specifically include the following sub-steps:
a substep S53 of determining video coding parameters of the picture resource;
in a specific implementation, after the picture resource to be converted into the video stream is obtained, the video coding parameters required for converting the picture resource into the video stream may be extracted, and the video coding parameters may include the width and the height of the container control.
Sub-step S54, the video networking server creating the container control using the video coding parameters.
After the width and the height of the container control contained in the video coding parameters are obtained, the container control can be created according to the width and the height of the container control.
Step 502, the video network server displays the picture resource in the corresponding container control;
in a specific implementation, the picture resources need to be presented in the control screen first, and then the display image of the control screen is captured, so that the picture resources can be converted into the video stream. Therefore, after the container control corresponding to the picture resource is created, the resource pictures need to be displayed on the screen of the container control one by one.
Step 503, the video network server generates a video stream according to the picture resource code in the container control;
after the resource pictures are displayed on the container control screen, the screen pictures can be captured, encoded and converted into video streams.
In the embodiment of the invention, the resource picture can be coded to generate the H.264 video stream with the appointed frame rate according to the H.264 protocol.
H.264 protocol: h.264, the highly compressed digital Video codec standard proposed by the Joint Video Team (JVT, Joint Video Team) consisting of the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG) jointly.
Step 504, the video network server outputs the video stream to the video network terminal.
After the picture resources are converted into an h.264 video stream, the h.264 video stream can be transmitted to a video network for external viewing.
Therefore, the acquired picture resources are displayed in the corresponding container control by creating the plurality of virtual container controls, and the resource pictures in the container controls are captured and then converted into the video streams, so that the multi-path picture resources are converted into the video streams in one server and are output to the video network, the multi-path concurrence of the video streams is realized, the server resources are saved, the server interface is clean and simple, and the human-computer interaction is friendly.
It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention. Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the invention.
