The unified video platform adopts a menu type configuration table mode to replace the traditional complex application programming, can realize complex application by using very few codes, and realizes infinite new service innovation.

Networking of the video network is as follows:

The video network is a centralized control network structure, and the network can be a tree network, a star network, a ring network and the like, but on the basis of the centralized control node, the whole network is controlled by the centralized control node in the 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 can be directly connected with the access switch or directly connected with 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 or 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.

The access network part can form a unified video platform (the part in the dotted circle), and a plurality of unified video platforms can form a video network; each unified video platform may be interconnected via metropolitan area and wide area video networking.

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.

Based on the characteristics of the video network, the core concept of the embodiment of the invention is provided, and the continuity of processing video stream in the video network video by the video network equipment can be improved by following the protocol of the video network.

Referring to fig. 5, a flowchart illustrating steps of an embodiment of a video stream processing method based on a video network according to the present invention is shown, where the method may be applied to a video network device, and the method may specifically include the following steps:

in step S101, a target video stream is acquired;

in the embodiment of the invention, the video networking equipment is in communication connection with the video networking server based on a video networking protocol, when the video networking equipment needs to acquire a video networking video from the video networking server, the video networking equipment can send an acquisition request for acquiring the video networking video to the video networking server, the video networking server receives the acquisition request and acquires a plurality of video networking video streams included in the video networking video, the video networking video streams have a sequential playing sequence, and the video networking video streams are respectively sent to the video networking equipment according to the sequential playing sequence.

The video network device sends video streams to the video network device, wherein the sending intervals between any two adjacent video network video streams sent by the video network server to the video network device are often the same, but the receiving intervals between any two adjacent video network video streams received by the video network device are often different due to the fact that communication connection between the video network device and the video network server fluctuates sometimes.

for example, the video networking server sends a1 st video networking video stream at 0ms, a 2 nd video networking video stream at 1ms, a 3 rd video networking video stream at 2ms, and a 4 th video networking video stream at 3 ms.

However, the video networking device receives the 1 st video networking video stream in 300ms, the 2 nd video networking video stream in 301ms, the 3 rd video networking video stream in 302ms, but the 4 th video networking video stream in 1045 ms.

In order to meet the real-time processing of the video stream, the video networking device directly processes the received video stream after receiving one video stream.

as such, the video networking device is unable to process multiple video networking video streams in the video networking video coherently. For example, when playing multiple video streams in a video stream, after receiving the 3 rd video stream, the 1 st to 4 th video streams cannot be processed coherently because it takes a long time to wait until the 4 th video stream is received.

therefore, in order to enable the video networking device to continuously process a plurality of video networking video streams in the video networking video, after the video networking device acquires a target video networking video stream included in the video networking video, step S102 may be performed, where the target video networking video stream is a video stream in the video networking video, and optionally, the target video networking video stream is a video stream in the video networking video except for a video stream whose sequential playing order is the last.

In step S102, storing the target video stream in a preset cache;

in the embodiment of the present invention, after the video networking device acquires the target video networking video stream, the target video networking video stream does not need to be directly processed, but the target video networking video stream may be stored in a preset cache, and when there are many video networking video streams stored in the preset cache, the video networking video stream stored in the preset cache is processed, which may specifically refer to the following steps.

In step S103, detecting whether an occupied rate of a preset cache is greater than a preset threshold;

If the occupied rate of the preset cache is greater than the preset threshold value, in step S104, sequentially processing all video streams stored in the preset cache space according to the playing sequence among all video streams;

all the video streams stored in the preset cache space can be sequentially sent or played according to the playing sequence among all the video streams.

in the embodiment of the invention, the video networking video comprises a plurality of video networking video streams, the video networking video streams have a sequential playing sequence, each video networking video stream has a sequential number, and the sequential number of the video networking video stream with the sequential playing sequence in front is smaller than the sequential number of the video networking video stream with the sequential playing sequence in back.

when any one of the video stream of the video network is stored, the sequence number of the video stream of the video network can be obtained first, then a storage position is allocated for the video stream of the video network in a preset cache, the video stream of the video network is stored at the storage position, then the sequence number of the video stream of the video network and the storage position form a corresponding table entry, and the corresponding table entry is stored in the corresponding relation between the stored sequence number and the storage position. The above operations are also performed when storing each of the other video networking video streams in the video networking video.

In the correspondence relationship between the stored sequence numbers and the storage positions, one column of the stored sequence numbers is stored in an order of the sequence numbers from small to large.

In this way, in this step, the sequence number arranged first may be obtained in the correspondence, then the storage location corresponding to the sequence number is searched in the correspondence, the video stream of the video network is obtained at the storage location in the preset cache, and the video stream of the video network is processed. And then acquiring the sequence numbers arranged in the second in the corresponding relation, and continuing to execute according to the process until each video stream stored in the preset cache is processed.

in another embodiment of the present invention, if the occupied rate of the preset cache is less than or equal to the preset threshold, the step S103 is returned to.

in order to improve the consistency of the video networking device in processing the video networking video stream in the video networking video as much as possible, the preset threshold may be set to a value greater than half of the preset cached storage space, for example, the preset threshold may be set to 70%, 80%, or 90% of the preset cached storage space.

Further, if a certain video stream is processed, the video stream is not processed any more, and therefore the video stream does not need to be stored in the preset cache, and the processed video stream can be deleted from the preset cache to save the storage space of the preset cache.

In the embodiment of the invention, a preset cache needs to be created in the video networking device in advance, when the bandwidth between the video networking server and the video networking device is larger, the transmission rate of the video networking video stream between the video networking server and the video networking device is faster, and when the bandwidth between the video networking server and the video networking device is smaller, the transmission rate of the video networking video stream between the video networking server and the video networking device is slower.

when the preset cache is full, if the video networking equipment continues to acquire other video networking video streams, the preset cache cannot store other video networking video streams in the preset cache due to the fact that the preset cache is full, and other subsequently received video networking video streams can only be discarded, so that the video networking equipment cannot process complete video networking videos.

in order to avoid discarding any one video stream of the video networking, so that the video networking device can process complete video of the video networking, when a preset cache is created in the video networking device in advance, the bandwidth between the video networking device and a sender of a target video stream of the video networking can be acquired; determining a storage space according to the bandwidth; and then creating a cache of the storage space in the video networking equipment, and using the cache as a preset cache.

When the storage space is determined according to the bandwidth, the space storage space corresponding to the bandwidth can be searched in the corresponding relation between the stored bandwidth and the storage space; in the correspondence relationship, the larger the bandwidth is, the larger the storage space is, and the smaller the bandwidth is, the smaller the storage space is.

In another embodiment of the present invention, the bandwidth between the video networking server and the video networking device may be changed continuously, so as to avoid discarding any video networking video stream, so that the video networking device can process a complete video networking video, and in the process of processing the video networking video stream stored in the preset cache, it may be detected whether the bandwidth is increased; and if the bandwidth is increased, increasing the storage space of the preset cache.

Specifically, the storage space corresponding to the bandwidth may be searched in the correspondence between the stored bandwidth and the storage space, a difference space between the searched storage space and the current storage space of the preset cache may be calculated, and then the difference space may be added to the preset cache.

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.
