Detailed ways

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

Aiming at the problem that the existing video networking technology does not have a method for statistics of service duration, the present invention discloses a core concept of receiving service data through a service server, according to the start time and dynamic frame information of video stream data contained in the service data. Determine the service duration of the video stream data, and send it to the second video network terminal for display. Thus, supervisors can know the running time of each service on each video network terminal in real time.

Referring to FIG. 1, there is shown a flow chart of steps of an embodiment of a service duration display method according to the present invention. The method can be applied to a video network, and the video network includes a first video network terminal, a video network server, and a service server. The second Internet-of-view terminal, where the first Internet-of-view terminal is configured to send service data to the Internet-of-view server, may specifically include the following steps:

Step 101, the service server receives the service data sent by the video network server; the service data includes video stream data, and the start time corresponding to the video stream data;

In the embodiment of the present invention, the first video networking terminal can actively report the service data generated during the operation of each service to the video networking server, and the service data is generated in real time and can reflect the real-time status of the service. After receiving the business data reported by the first video network terminal, the video network server can transmit the business data to the service server through the video network transparent transmission protocol. Data server for data analysis.

In one example, the service data may include video stream data and a start time corresponding to the video stream data.

When a certain service on the first terminal (the service may include live broadcast, video TV, conference, video surveillance, etc.) starts to run, the start time can be recorded, and the start time and the video stream data generated by the service can be sent to the The video network server is sent to the business server for data analysis through the video network server.

Step 102, identifying dynamic frame information in the video stream data;

In practical applications, the video stream data may include dynamic frames and static frames, and their corresponding bandwidth requirements are different. According to the dynamic frames and static frames, the bandwidth requirements of services at different stages can be known.

In the embodiment of the present invention, in order to know the bandwidth requirements of the service at different stages, dynamic frame information in the video stream data can be identified.

Specifically, the dynamic frame extraction technology of the data increment algorithm, such as the OpenCV image detection algorithm, can be used to analyze whether each frame picture is a dynamic picture or a static picture, so as to extract the dynamic frame information in the video stream data.

Step 103, using the startup time and the dynamic frame information to calculate the service duration of the video stream data;

After the dynamic frame information in the video stream data is determined, the start time and the dynamic frame information can be used to calculate the service duration of the video stream data.

Step 104: Send the service duration to the second video network terminal for display.

After the service duration is determined, the service duration may be sent to the second video networking terminal for display.

In an example, the service duration of each service of a single Internet-of-view terminal within a certain period of time (eg, one day) can be counted, and the service duration of each service of all terminals in a certain area within a certain period of time can also be counted.

This embodiment of the present invention analyzes the service data reported by the first-view network terminal through the service server, determines the service duration of the video stream data according to the start time and dynamic frame information of the video stream data contained in the service data, and sends the data to the second-view video network. displayed on the network terminal. Thus, supervisors can know the running time of each service on each video network terminal in real time.

Referring to FIG. 2, a flow chart of steps of an embodiment of a method for displaying service duration of the present invention is shown, which may specifically include the following steps:

Step 201, the service server receives the service data sent by the video network server; the service data includes video stream data, and the start time corresponding to the video stream data;

In the embodiment of the present invention, the first video networking terminal can actively report the service data generated during the operation of each service to the video networking server, and the service data is generated in real time and can reflect the real-time status of the service. After receiving the business data reported by the first video network terminal, the video network server can transmit the business data to the service server through the video network transparent transmission protocol. The video stream data is sent to the service server.

In one example, the service data may include video stream data and a start time corresponding to the video stream data.

When a certain service on the first terminal (the service may include live broadcast, video TV, conference, video surveillance, etc.) starts to run, the start time can be recorded, and the start time and the video stream data generated by the service can be sent to the The video network server is sent to the business server for data analysis through the video network server.

Step 202, identifying dynamic frame information in the video stream data;

In practical applications, the video stream data may include dynamic frames and static frames, and their corresponding bandwidth requirements are different. According to the dynamic frames and static frames, the bandwidth requirements of services at different stages can be known.

In the embodiment of the present invention, in order to know the bandwidth requirements of the service in different stages, the dynamic frame information in the video stream data can be identified by the time duration statistics system deployed on the service server.

Specifically, the duration statistics system can extract dynamic frame information in the video stream data by analyzing whether each frame is a dynamic or static image through a data increment algorithm dynamic frame extraction technology, such as OpenCV image detection algorithm.

In an example, if the service of uploading video stream data is monitoring video data, after the dynamic frames are extracted, a dynamic frame filtering module may be added to filter out repetitive and useless dynamic frames.

Step 203, obtaining the current system time;

Step 204, using the startup time and the current system time to calculate the total duration of the video stream data;

In the embodiment of the present invention, the total duration of the video stream data generated by the service operation from the start time to the current time can be calculated by the difference between the start time and the current system time. At the same time, the total time is growing until the business ends.

Step 205, using the dynamic frame playback duration and the dynamic frame quantity to calculate the dynamic duration of the video stream data;

In practical applications, when the resolution of the video stream data remains unchanged, the playback duration of each frame of the video stream data is fixed. Therefore, according to the number of dynamic frames and the playback duration of dynamic frames, the video can be calculated The total playing duration of all dynamic frames in the stream data is used to obtain the dynamic duration of the video stream data.

Step 206: Calculate the static duration of the video stream data by using the total duration and the dynamic duration.

After the total duration and the dynamic duration of the video stream are obtained, the static duration of the video stream data can be calculated according to the difference between the total duration and the dynamic duration.

Step 207: Send the service duration to the second video network terminal for display.

After the service duration is determined, the service duration may be sent to the second video networking terminal for display.

In an example, the service duration of each service of a single Internet-of-view terminal within a certain period of time (eg, one day) can be counted, and the service duration of each service of all terminals in a certain area within a certain period of time can also be counted.

The business server can conduct business duration (including real-time total duration, dynamic duration and static duration) statistics on the data uploaded by the video network server through the duration statistics system.

The second-view network terminal can periodically obtain from the service server the service duration of each service running on all the first-view network terminals in a certain area within a certain period of time, and also separately obtain the services running on any first-view network terminal within a certain period of time. business hours.

In the embodiment of the present invention, the service data further includes identification information and service type of the first Internet-of-view terminal; step 207 may specifically include the following sub-steps:

S11, bind the identification information, the service type and the corresponding service duration to obtain binding information;

S12: Send the binding information to the second Internet-of-view terminal for display.

In this embodiment of the present invention, the service server may bind the identification information of the first-view Internet terminal that generates the service data, the service type of the service, and the service duration of the video stream data generated by the service, and send the binding information to The second video is displayed on the networked terminal.

In an example, the second video network terminal can visually display the overall duration status of a certain area, or the duration status of a certain terminal in the form of a pie chart or a line chart.

Referring to FIG. 4 , a schematic display diagram of a method for displaying service duration of the present invention is shown.

As shown in the figure, in this embodiment of the present invention, the total duration of the services running on the FirstView terminal 401 in one day can be counted, and the services running on the FirstView terminal 401 on the day include videophone A, conference B, live broadcast, etc. C and idle state D with no business running. Through FIG. 4 , the operation of the service on the first-view Internet-connected terminal 401 can be seen intuitively.

In an example, the proportion of the business duration of each business in a day may also be marked on FIG. 4 . And, mark the dynamic duration and static duration of each business. This application does not specifically limit the display manner of the service duration on the second-view network terminal.

Video networking is an important milestone in network development. It is a real-time network that can realize real-time transmission of high-definition video, and push many Internet applications to high-definition video, high-definition face-to-face.

Video networking adopts real-time high-definition video switching technology, which can provide required services on a network platform, such as high-definition video conferencing, video surveillance, intelligent monitoring and analysis, emergency command, digital broadcast TV, delayed TV, online teaching, live broadcast , VOD on demand, TV mail, personal recording (PVR), intranet (self-organized) channels, intelligent video broadcast control, information release and other dozens of video, voice, picture, text, communication, data and other services are all integrated into one The system platform can realize high-definition video playback through TV or computer.

In order to make those skilled in the art better understand the embodiments of the present invention, video networking is introduced as follows:

Some of the technologies used in the Internet of Things are as follows:

Network Technology

The network technology innovation of the video network improves the traditional Ethernet (Ethernet) to face the potentially huge video traffic on the network. Different from pure network packet switching (Packet Switching) or network circuit switching (Circuit Switching), the Internet of View technology adopts Packet Switching to meet the requirements of Streaming. The Internet of Things technology has the flexibility, simplicity and low price of packet switching, and at the same time has the quality and security assurance of circuit switching, and realizes the entire network of switched virtual circuits and seamless connection of data formats.

Switching Technology

The Internet of Things adopts the asynchronous and packet switching advantages of Ethernet, and eliminates the defects of Ethernet under the premise of full compatibility. User data does not need any format conversion in the whole network. Video networking is a more advanced form of Ethernet. It is a real-time switching platform that can realize the real-time transmission of large-scale high-definition video across the entire network that cannot be achieved by the Internet, and push many network video applications to high-definition and unified.

Server Technology

The server technology on the video networking and unified video platform is different from the server in the traditional sense. Its streaming media transmission is based on connection-oriented, and its data processing capability has nothing to do with traffic and communication time. A single network layer can contain information. command and data transmission. For voice and video services, the complexity of video networking and unified video platform streaming media processing is much simpler than data processing, and the efficiency is greatly improved by more than 100 times compared to traditional servers.

Storage Technology

The ultra-high-speed storage technology of the unified video platform adopts the most advanced real-time operating system in order to adapt to the media content of large capacity and large flow, and maps the program information in the server instruction to the specific hard disk space, and the media content no longer passes through the server. It is directly delivered to the user terminal in an instant, and the general waiting time of the user is less than 0.2 seconds. The optimized sector distribution greatly reduces the mechanical movement of the hard disk head seeking, and the resource consumption only accounts for 20% of the same level of IP Internet, but it generates 3 times more concurrent traffic than traditional hard disk arrays, and the overall efficiency is increased by more than 10 times.

Network Security Technology

The structural design of the Internet of Things completely eliminates the network security problems that plague the Internet through separate licensing for each service and complete isolation of equipment and user data. Generally, anti-virus programs and firewalls are not required, and hackers and viruses are prevented from attacking. , to provide users with a structured worry-free safety network.

Service Innovation Technology

The unified video platform integrates services and transmission. Whether it is a single user, a private network user, or the aggregate of a network, it is just an automatic connection. User terminals, set-top boxes or PCs are directly connected to the unified video platform to obtain a variety of multimedia video services in various forms. The unified video platform adopts the "recipe-style" table matching mode to replace the traditional complex application programming. It can realize complex applications with very little code, and realize "unlimited" new business innovation.

The networking of the Internet of Things is as follows:

The Internet of Things is a centralized control network structure. The network can be a tree network, a star network, a ring network, etc., but on this basis, a centralized control node is required in the network to control the entire network.

As shown in Figure 6, the Internet of Things is divided into two parts: the access network and the metropolitan area network.

The equipment in the access network part can be mainly divided into three categories: node server, access switch, and terminal (including various set-top boxes, coding boards, memory, etc.). The node server is connected to the access switch, and the access switch can be connected to multiple terminals and can be connected to Ethernet.

The node server is a node in the access network that functions as a centralized control, and can control access switches and terminals. The node server can be directly connected to the access switch, or it can be directly connected to the terminal.

Similarly, the equipment in the metropolitan area network can also be divided into three categories: metropolitan area server, node switch, and node server. The metropolitan area server is connected with the node switch, and the node switch can be connected with multiple node servers.

The node server is the node server of the access network part, that is, the node server belongs to both the access network part and the metropolitan area network part.

The metropolitan area server is a node with centralized control function in the metropolitan area network, which can control the node switch and the node server. The metropolitan area server can be directly connected to the node switch or directly connected to the node server.

It can be seen that the entire VisionLink network is a network structure controlled by layers and centralized, and the network controlled by the node server and the metro server can be tree, star, ring and other structures.

Figuratively, the access network part can form a unified video platform (the part in the dashed circle), and multiple unified video platforms can form a video network; each unified video platform can be interconnected through the metro and wide-area video networks.

2. Definition of Internet Data Packets

2.1 Definition of Access Network Data Packets

The data packet of the access network mainly includes the following parts: destination address (DA), source address (SA), reserved bytes, payload (PDU), and CRC.

As shown in the table below, the data packets of the access network mainly include the following parts:

DA SA Reserved Payload CRC

in:

The destination address (DA) consists of 8 bytes (byte), the first byte indicates the type of the data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.), there are up to 256 possibilities, The second to sixth bytes are the metropolitan area network address, and the seventh and eighth bytes are the access network address;

The source address (SA) is also composed of 8 bytes (byte), and the definition is the same as the destination address (DA);

Reserved bytes consist of 2 bytes;

The payload part has different lengths according to different types of datagrams. If it is a variety of protocol packets, it is 64 bytes. If it is a single multicast data packet, it is 32+1024=1056 bytes. Of course, it is not limited to Above 2 kinds;

The CRC consists of 4 bytes, and its calculation method follows the standard Ethernet CRC algorithm.

2.2 MAN Data Packet Definition

The topology of the metropolitan area network is a graph. There may be two or even more than two connections between two devices, that is, there may be more than two connections between node switches and node servers, between node switches and node switches, and between node switches and node servers. kind of connection. However, the metropolitan area network address of the metropolitan area network equipment is unique. In order to accurately describe the connection relationship between the metropolitan area network equipment, a parameter: label is introduced in the embodiment of the present invention to uniquely describe a metropolitan area network equipment.

The definition of labels in this specification is similar to the definition of MPLS (Multi-Protocol Label Switch, Multi-Protocol Label Switch) labels. Assuming that there are two connections between device A and device B, the data packets from device A to device B have 2 labels, packets from device B to device A also have 2 labels. Labels are divided into incoming labels and outgoing labels. Assuming that the label (incoming label) of the data packet entering device A is 0x0000, the label (outgoing label) of the data packet when it leaves device A may become 0x0001. The network access process of the metropolitan area network is a network access process under centralized control, which means that the address allocation and label allocation of the metropolitan area network are dominated by the metropolitan area server, and the node switches and node servers are all passively executed. Different from MPLS label assignment, MPLS label assignment is the result of mutual negotiation between switches and servers.

As shown in the table below, the data packets of the metropolitan area network mainly include the following parts:

DA SA Reserved Label Payload CRC

Namely destination address (DA), source address (SA), reserved bytes (Reserved), label, payload (PDU), CRC. Among them, the format of the label can refer to the following definition: the label is 32 bits, of which the upper 16 bits are reserved, and only the lower 16 bits are used, and its position is between the reserved bytes of the data packet and the payload.
