Problems solved by technology

[0008] Generally speaking, the market does have demand for remote backup and disaster recovery of video data. However, for such a huge amount of data and the fact that old video data needs to be deleted regularly, it is extremely uneconomical to pay expensive costs.
[0009] At present, due to the large number of suppliers, there are many suppliers on the front end, server end, and network end. The disaster recovery backup of video data is costly, heavy workload, and troublesome in operation and maintenance.
Therefore, suppliers usually ignore the remote backup and disaster recovery requirements of video data
On-site technical support personnel lack training and experience. Even if there are problems such as viruses / trojan horses, malicious access, malicious login, and malicious data tampering in the system, they are still ignorant

Embodiment 1

[0043] see Figure 1-Figure 2 , a kind of video multipoint transmission method based on UDP packet copying, comprises the following steps:

[0044] S1: Before use, connect the Ethernet network port P0 of the video multiplexing device VMD directly to the management platform. The Ethernet network port P0 uses a predefined management IP address and port. The administrator issues management commands based on the port, and the video multiplexing The Ethernet network port P0 of the device VMD has an admIP address, and when P0 receives a configuration message in the agreed format from the port, it performs configuration;

[0045]S2: The video reporting node VRN uses Ethernet to connect to the Ethernet network port P1 of the video multiplexing device VMD, the local video server LVS is connected to the Ethernet network port P2 of the video multiplexing device VMD, and the remote video server RVS is connected to the video multiplexing device Use the Ethernet port P3 of the device VMD; ...

Embodiment 2

[0055] When configuring the video multiplexing device (VMD) implementation scheme of the present invention, it can be based on: FPGA, FPGA (+ARM core), ASIC, CPLD, DSP, single-chip microcomputer, ARM chip, RISC-V chip, PC system, mobile phone system, Custom hardware or the like implementations, including but not limited to the described implementations.

[0056] When configuring the first interface P1, the second interface P2, and the third interface P3 of the video multiplexing device (VMD) in the present invention for selection, it can be: USB, parallel port, serial port, dual-port SRAM, network port, optical fiber, WIFI, Infrared LED, laser, 4G / 5G module link, etc., including but not limited to the interface. When we describe the number of interfaces of the video multiplexing device (VMD), it can be: 1-N collection sources, that is, the normal interface for reporting, 1-M local video servers, that is, the normal interface for data reporting, and 1-M remote End video server...

Abstract

The invention discloses a video multi-point transmission method based on UDP packet copying and sending, and the method comprises the following steps that before use, an Ethernet port P0 of a video multiplexing device VMD is directly connected to a management platform, the Ethernet port P0 adopts a predefined management IP address and a port, an administrator sends out a management command based on the port, wherein the Ethernet port P0 of the video multiplexing device VMD has an admIP address; and when the P0 receives the configuration message of the agreed format from the port, configuration is performed. According to the video multi-point transmission method based on UDP packet copying and sending, the huge cost and the huge workload caused by customizing software and routers, adopting virtual storage and increasing a special copying server are overcome, and the requirements of remote disaster recovery and real-time backup of video data are effectively met.

Description

technical field [0001] The invention relates to the technical field of video multipoint transmission, in particular to a method for video multipoint transmission based on UDP packet copying. Background technique [0002] As the market evolves and technology advances, video data is used in many occasions. Of course, since long-term storage of video data requires a large storage space, the cost of cloud storage is too high, and cloud storage is easy to cause privacy leakage, so it is not suitable for video data storage in public places. [0003] However, how to reliably store the video data, and at the same time, when an abnormality occurs, there is a remote backup, so that the responsibility for the event at that time can be determined from the playback of the video data. [0004] The usual method is to start a service on the video storage server, and forward a large amount of data to the remote backup storage server in real time while writing to the local disk. [0005] On...
