Description

Terminal state display method and device based on video network

Technical Field

The invention relates to the technical field of video networking, in particular to a terminal state display method and a terminal state display device based on the video networking.

Background

In the video networking security conference system, video networking terminal equipment has security characteristics, such as network access authentication, data encryption and the like, and when a user uses a video networking terminal to carry out video conference service, whether the characteristics are started or not can be manually controlled. After the security characteristic of the video networking terminal equipment is started, the terminal can carry out network access authentication, and audio and video data in a conference are encrypted in the transmission process; after the safety characteristic of the video network terminal equipment is closed, the terminal does not carry out network access authentication, and audio and video data in the conference are not subjected to encryption processing in the transmission process.

In the current video conference system, because data sent by a terminal with a security feature being turned on is a ciphertext, when the ciphertext data is sent to another terminal without the security feature being turned on, the ciphertext data cannot be decoded and played, which requires a conference organizer to give priority to whether the property of initiating a conference is a secure conference or a normal conference when initiating the conference. For the secure conference, all terminals participating in the conference need to keep the security feature on; for a normal conference, all terminals participating in the conference need to keep the security feature off.

The video networking conference is controlled to be initiated through the video networking conference scheduling software, but a communication channel is not established between the video networking conference scheduling software and the video networking terminal, so that the video networking conference scheduling software cannot acquire the current security state of the video networking terminal, namely cannot determine whether the video networking terminal is started with the security characteristic.

In an embodiment of the present invention, the video network terminal may receive a status query request generated by the video network conference scheduling terminal and transmitted through the transparent transmission channel by the conference management server, so that the video network terminal may generate status response data corresponding to the status query request according to the received status query request, where the status response data may be data representing a security status of the video network terminal.

Step 302, the video network terminal generates status response data according to the status query request, and transmits the status response data to the conference management server through the transparent transmission channel; the conference management server is used for transmitting the state response data to the conference scheduling terminal; and the conference scheduling terminal is used for displaying the state response data in a preset state list.

In an embodiment of the present invention, the video networking terminal may receive a status query request generated by the video networking conference scheduling terminal and transparently transmitted by the conference management server, and query the security status of itself in response to the status query request, and generate status response data according to a query result, where the status response data may be data representing the security status of the video networking terminal.

In an embodiment of the present invention, the terminal of the video network has a security feature, and step 302 may include the following sub-steps:

substep S51, the video network terminal receives the first video network message transmitted by the conference management server; the first video network message comprises the status query request;

in one embodiment of the invention, the video network terminal can receive a state query request transmitted by the conference management server through the transparent transmission channel, and the state query request can be transmitted in the form of a message in the transparent transmission channel; because the conference management server and the video network terminal can be in communication connection based on a video network protocol, the message received by the video network terminal is a first video network message, and the first video network message comprises a state query request.

Substep S52, the video network terminal inquires the state of the safety characteristic according to the state inquiry request and generates state response data aiming at the safety characteristic;

in one embodiment of the invention, after receiving a first video network message from a sending end of a conference management server, a video network terminal analyzes the first video network message and extracts a state query request contained in the first video network message; and responding to the extracted state query request, querying the security state of the terminal, namely querying the state of the security characteristic of the terminal, and generating state response data according to the query result, wherein the state response data can be data representing the security state of the video network terminal, and the state response data can comprise first state response data representing that the security state of the video network terminal is safe or second state response data representing that the security state of the video network terminal is unsafe.

In one embodiment of the present invention, the sub-step S52 may include the following sub-steps:

substep S521, when the state of the security feature is on, the video network terminal generates first state response data; the first state response data is data indicating that the safety characteristic is opened;

in one embodiment of the invention, the terminal of the video network inquires about the security state of the terminal of the video network, and in one condition, when the security characteristic of the terminal of the video network is opened, the security state of the terminal of the video network is safe, and first state response data is generated according to the security state and indicates that the security characteristic of the terminal of the video network is opened.

Substep S522, or when the state of the security feature is off, the video network terminal generates second state response data; the second state response data is data indicating that the security feature is closed.

In one embodiment of the invention, the terminal of the visual network inquires about its own security state, and in another case, when its own security feature is turned off, the security state of the terminal of the visual network is unsafe, and second state response data is generated according to the security state, which indicates that the security feature of the terminal of the visual network is turned off.

Substep S53, the video network terminal generates a second video network message; the second video networking message comprises the status response data for the security characteristic;

the video network terminal can inquire the state of the security characteristic of the video network terminal according to the received state inquiry request and generate state response data according to the state of the security characteristic.

In one embodiment of the invention, because the video network terminal can realize communication with the video network conference scheduling terminal through the transparent transmission channel via the conference management server, the video network terminal can transmit the state response data generated according to the state query request in the transparent transmission channel in the form of a message; the video network terminal and the conference management server can be in communication connection based on a video network protocol, and the video network terminal can package the status response data into a second video network message so that the status response data can be transmitted in a transparent transmission channel in the form of the second video network message.

And a substep S54, the video network terminal transmits the second video network message to the conference management server.

In an embodiment of the present invention, since the conference management server is used as an intermediate device between the conference scheduling terminal and the video network terminal, the video network terminal may transmit the status response data encapsulated into the second video network packet to the conference management server, so that the conference management server transmits the status response data included in the second video network packet to the video network conference scheduling terminal.

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.

Referring to fig. 4, it shows an application scenario diagram of the terminal status display method based on video networking of the present invention, in a video conference of video networking, the involved devices may include a video conference scheduling terminal, a conference management server, a video networking server and a video networking terminal; for the state of the security characteristic of the video network terminal, a key management server can also manage the video network conference scheduling terminal and data interacted with the video network terminal by the video network terminal.

As can be seen from fig. 4, since no communication channel is established between the video network conference scheduling terminal and the video network terminal, the conference management server may establish a transparent transmission channel, which enables the conference management server and the video network scheduling terminal to be in communication connection based on the internet protocol, and the conference management server and the video network terminal to be in communication connection based on the video network protocol.

In the video network conference scheduling terminal, a refreshing function can be added on an original terminal state list of video network conference scheduling software to update the terminal state.

After an operator clicks and refreshes, namely when the video networking conference terminal detects the query operation aiming at the terminal state list, the state query request packaged into a first internet message can be sent to the conference management system through the transparent transmission channel; the conference management system repackages the state query request of the first internet message into a first video network message based on a video network transparent transmission protocol, and transmits the first video network message to a video network server through a switch;

after the state query request enters the video networking server, the communication protocol is changed from an IP protocol to a v2v protocol, namely, the Internet protocol is changed into a video networking protocol;

after receiving the status query request, the video network terminal, i.e., the set-top box, may view the local configuration information, and generate status response data '01' when the security feature is on, and generate status response data '00' when the security feature is off. The state response data can return to the video network conference scheduling terminal according to the original path;

when the video network conference scheduling terminal does not receive the state response data sent by the set top box after sending the state query request for 8s, the set top box can be considered to be in an off-line state, the terminal name is displayed as grey and can not be selected in the terminal list, and an off-line character is remarked after the name; when receiving the terminal response information '01', the terminal is considered to have opened the security feature, at this time, the corresponding terminal name in the terminal list is in a black selectable state, and the name is annotated with an 'encrypted' word; when the terminal response information '00' is received, the terminal is considered not to start the security feature, at this time, the corresponding terminal name in the terminal list is in a black selectable state, and no remark is made after the name;

the video network conference scheduling terminal can respond to data according to the state of each video network terminal when a conference is initiated to each video network terminal according to the security state of each video network terminal in the terminal state list at the moment, encrypts data sent by the terminal with the security characteristic started during the video conference, sends the encrypted ciphertext data to the set top box, and starts the conference; and the data sent by the terminal without starting the security feature is not encrypted, and the unencrypted plaintext data is sent to the set top box to start the conference.

Therefore, when a client initiates the video conference of the video network, the client can acquire the state of the terminal at any time so as to initiate different types of video conferences according to the safety requirement.

As shown in fig. 8, the video network is divided into an access network and a metropolitan 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 controlled by a hierarchical centralized way, and the network controlled by the node server and the metropolitan area server can be in various structures such as a tree, a star, a ring and the like.

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.

The disk array module 904 mainly implements control over the hard disk, including initialization, read-write, and other operations on the hard disk; the CPU 903 is mainly responsible for protocol processing with an access switch and a terminal (not shown), configuring an address table 905 (including a downlink protocol packet address table, an uplink protocol packet address table, and a data packet address table), and configuring the disk array module 904.

The access switch:

wherein, the packet (uplink data) coming from the downlink network interface module 1001 enters the packet detection module 1005; the packet detection module 1005 detects whether the Destination Address (DA), the Source Address (SA), the packet type, and the packet length of the packet meet the requirements, if so, allocates a corresponding stream identifier (stream-id) and enters the switching engine module 1003, otherwise, discards the stream identifier; the packet (downstream data) coming from the upstream network interface module 1002 enters the switching engine module 1003; the incoming data packet of the CPU module 1004 enters the switching engine module 1003; the switching engine module 1003 performs an operation of looking up the address table 1006 on the incoming packet, thereby obtaining the direction information of the packet; if the packet entering the switching engine module 1003 goes from the downlink network interface to the uplink network interface, the packet is stored in a queue of a corresponding packet buffer 1007 in combination with a stream identifier (stream-id); if the queue of the packet buffer 1007 is nearly full, it is discarded; if the packet entering the switching engine module 1003 does not go from the downlink network interface to the uplink network interface, the data packet is stored into the queue of the corresponding packet buffer 1007 according to the direction information of the packet; if the queue of the packet buffer 1007 is nearly full, it is discarded.

The switching engine module 1003 polls all packet buffer queues, which in this embodiment of the invention is divided into two cases:

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 the types of different datagrams, 64 bytes if various protocol packets, 32+1024=1056 bytes if single-multicast data packets, and certainly 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., more than 2 connections between a node switch and a node server, between a node switch and a node switch, and between 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 divided into an in label and an out label, and assuming that the label (in label) of the data packet entering the device a is 0x0000, the label (out label) of the data packet leaving the device a may become 0x0001. 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 all passively executed, which is different from label allocation of MPLS, which 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, one of the core concepts of the embodiment of the invention is provided, and a transparent transmission channel is established by the conference management server according to the protocol of the video network, so that data interaction and communication can be carried out between video network conference scheduling software and a video network terminal through the transparent transmission channel, and the effects of inquiring the state of the video network terminal and displaying the state of the video network terminal by the video network conference scheduling software are realized.
