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 block diagram of a video query system based on a video network according to an embodiment of the present invention is shown, the system at least includes: video server 01 that is located the internet and be located the video networking equipment in the video networking, video networking equipment includes video networking gateway 02, video networking server 03 and video networking 04.

The video server 01 stores therein a plurality of videos.

The user can access the video network via the video network gateway 02 on the internet Web page, that is, the video network gateway 02 can be an interactive interface between the video network and the internet Web page.

The video server 01 can perform data interaction with the video network through the cat 04, that is, the cat 04 can be an interactive interface between the video network and the video server.

Namely, the internet Web page is in communication connection with the video networking gateway 02, and the video server 01 is in communication connection with the video modem 04.

Interaction data between devices in the video network during data interaction often needs to be forwarded via the video network server 03.

Therefore, the video networking gateway 02 is in communication connection with the video networking server 03 based on a video networking protocol, and the video networking server 03 is in communication connection with the video networking cat 04 based on the video networking protocol.

Referring to fig. 2, a flowchart illustrating steps of a video query method based on a video network according to an embodiment of the present invention is shown, where the method is applied to the system shown in fig. 1, and the method may specifically include the following steps:

in step S101, the video networking device receives a video query request sent via an internet Web page, where the video query request carries a target UCL (Uniform Content Label) in the form of a character string;

in the present application, when a user needs to search for a video in a video server in an internet Web page, the user may not search for the video based on the URL of the video, but may search for the video based on the UCL of the video,

the UCL includes at least: a content description attribute and a content management attribute;

In which, whenever a video is stored in a video server in advance, the UCL of the video can be set in the video server, and the UCL of the video can be one or more.

Therefore, a user can input a video query request on an internet Web page, where the video query request carries a target unified content label UCL in the form of a character string, and then send the video query request to a video networking gateway included in a video networking device via the internet Web page.

The video query request is received by a video networking gateway in the video networking device.

In step S102, the video networking device sends the video query request to the video server;

in the application, a user queries videos in video servers located in the internet in an internet Web page, and needs to query the videos in the video servers located in the internet through the video network. And the Internet Web page sends the video query request to the video networking gateway, wherein the video query request is a video query request of an Internet protocol.

Therefore, in order to enable the video query request to smoothly reach the video server after being relayed in the video network, the video network gateway needs to convert the video query request of the internet protocol into the query request of the video network protocol.

In the video network, the video modem can perform data interaction with the video server, so that the video network gateway needs to send the query request of the video network protocol to the video modem, so that the video modem converts the query request of the video network protocol into the video query request of the internet protocol, and then sends the video query request of the internet protocol to the video server.

However, since the internet of vision gateway and the internet of vision cat are not directly connected in communication, but indirectly connected in communication via the internet of vision server, the internet of vision gateway first needs to send the query request of the internet of vision protocol to the internet of vision server, so that the internet of vision server forwards the query request of the internet of vision protocol to the internet of vision cat, and then the internet of vision cat converts the query request of the internet of vision protocol into the video query request of the internet protocol, and sends the video query request of the internet protocol to the video server.

In step S103, the video server receives the video query request;

in step S104, the video server searches for a video matching the target UCL according to the video query request;

in one embodiment, if the target UCL is one, then the database is looked up for videos for which the UCL includes the target UCL.

In another embodiment, if the number of target UCLs is at least two, for any one target UCL, the video including the target UCL may be searched in the database, the above operation is performed for each other target UCL as well, then whether duplicate videos exist in all searched videos is detected, if duplicate videos exist, the searched videos are deduplicated, and the remaining videos are videos matched with the target UCL.

Alternatively, in yet another embodiment, if the target UCLs are at least two, videos in which the UCLs include at least two target UCLs at the same time, and the like, can be searched in the database.

In step S105, the video server sends the found video to the video networking device;

in order to make the internet Web page get the video found by the video server, the video server needs to send the found video to the internet Web page via the video network. The video cat in the video network can perform data interaction with the video server, so that the video server can send the searched video to the video cat in the video network equipment, and then the video cat receives the searched video.

However, the video server is located in the internet, so the video stored in the video server is often an internet protocol video, and thus the video searched by the video server in the database is also often an internet protocol video, so in order to enable the internet protocol video to smoothly reach an internet Web page after the internet is relayed, it is necessary for each device in the internet to be able to identify relevant information in the searched video, such as a destination address and the like, and therefore, the cat needs to convert the searched internet protocol video into the internet protocol video,

and then sending the video of the video networking protocol to the video networking server, and after receiving the video of the video networking protocol, the video networking server forwards the video of the video networking protocol to the video networking equipment.

In step S106, the video networking device receives the found video;

in step S107, the video networking device transmits the found video to the internet Web page.

In the application, the internet Web page does not support the video networking protocol and supports the internet protocol, so that after receiving the video of the video networking protocol, the video networking device needs to convert the video of the video networking protocol into the video of the internet protocol and then send the video of the internet protocol to the internet Web page.

And then, the Internet Web page can display the searched video for the user to select to play or store and the like.

In an embodiment of the present application, the number of target UCLs carried by the video query request is multiple, and the number of videos found by the video server is multiple.

As such, for each video found, among the plurality of target UCLs, the video server may determine the number of target UCLs that match the native UCLs of that video.

For example, assuming that the target UCL carried by the video query request includes UCL1, UCL2, and UCL3, if the inherent UCL in the video found in the video server includes UCL1, but does not include UCL2 and UCL3, the number of target UCLs matching the inherent UCL of the video is 1, and if the inherent UCL in one video found in the video server includes UCL1 and UCL3, but does not include UCL2, the number of target UCLs matching the inherent UCL of the video is 2.

And then generating sequencing information among the searched videos according to the sequence of at least the number corresponding to each video, wherein the number corresponding to the video comprises the number of target UCLs matched with the inherent UCLs of the videos in the target UCLs.

For example, assuming that the found video includes video a, video B, and video C, and the number of target UCLs matching the inherent UCL of video a is 1, the number of target UCLs matching the inherent UCL of video B is 2, and the number of target UCLs matching the inherent UCL of video C is 3, the ordering information between video a, video B, and video C is: video C precedes video B, which precedes video a.

Then, the sequencing information is sent to the video networking equipment, the video networking equipment receives the sequencing information among the videos sent by the video server, and then the sequencing information can be sent to an internet Web page, so that the internet Web page can display the searched videos according to the sequencing information.

When the number of the target UCLs matched with the inherent UCL of one video is larger, the possibility that the video is the video which is most desired to be inquired by the user is higher, and therefore, the searched videos are displayed according to the sequencing information, so that the user can quickly find the video which is most desired to be inquired by the user, the time for the user to manually search the video which is most desired to be inquired by the user in the searched videos can be saved, the user operation can be simplified, and the user experience can be improved.

In one embodiment of the application, a plurality of target UCLs are carried by the video query request, and a plurality of videos are found by the video server;

thus, for each found video, in a plurality of target UCLs, the video server may determine a target UCL matched with the inherent UCL of the video, and then obtain the weight of each matched target UCL, wherein in the present application, when a user inputs a video query request in an internet Web page, the weight of each target UCL is specified in the video query request, and the higher the weight of the UCL is for the user to query the video, the lower the weight of the UCL is for the user to query the video is, so that the weight of each matched target UCL can be directly obtained from the video query request.

And determining the matching degree between the video and the multiple target UCLs carried by the video query request according to the weights of the matched target UCLs, for example, adding the weights of the matched target UCLs to obtain the matching degree between the video and the multiple target UCLs carried by the video query request.

And then generating the searched sequencing information among the plurality of videos according to the sequence of the matching degree corresponding to each video from high to low, wherein the matching degree corresponding to the video is determined according to the weight of each target UCL matched with the inherent UCL of the video in the plurality of target UCLs.

And then, sending sequencing information to the video networking equipment, receiving the sequencing information among the videos sent by the video server by the video networking equipment, and then sending the sequencing information to an Internet Web page, so that the Internet Web page displays the searched videos according to the sequencing information.

When the matching degree between one video and a plurality of target UCLs carried by the video query request is higher, the possibility that the video is the video which is most desired to be queried by a user is higher, and therefore, the searched videos are displayed according to the sequencing information, so that the user can quickly find the video which is most desired to be queried by the user, the time for the user to manually search the video which is most desired to be queried in the searched videos can be saved, the user operation is simplified, and the user experience is improved.

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.

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.
