Embodiment 1

[0028] Server centralized management mode

[0029] After the monitoring terminal is powered on, its duplex mode is set to auto-negotiation, and the network interface rate is set to auto-negotiation. Follow-up adjustments will be made according to the actual situation.

[0030] The monitoring server obtains relevant information of the monitoring terminal, and the information mainly includes the rate of sending video data and the protocol type of the carrying video data. After the monitoring terminal is powered on, it registers with the monitoring server. During the registration process, the monitoring server will be notified of the number of code streams it supports, the rate of each code stream (average rate in seconds), and the protocol that carries each code stream. The monitoring server saves this information locally. When the subsequent client requests a certain live stream of the monitoring terminal to the monitoring server, the monitoring server learns the rate that th...

Embodiment 2

[0035] Monitoring terminal in stand-alone mode

[0036] The monitoring terminal in the independent operation mode is not controlled by the monitoring server, so it does not rely on the monitoring server to independently set the working mode. The video terminal device itself knows information such as the size of the data stream sent externally by the current network interface of the monitoring terminal and whether the data packet bearer protocol is TCP or UDP. The monitoring terminal adjusts the working mode of its own network interface according to the information it knows.

[0037]After the monitoring terminal is powered on, its duplex mode is set to auto-negotiation, and the network interface rate is set to auto-negotiation. Follow-up adjustments will be made according to the actual situation.

[0038] If the rate at which the monitoring terminal sends video data is less than or equal to the preset threshold, the rate of the network interface of the monitoring terminal is ...

Abstract

The present invention provides a method for adjusting the working mode of the monitoring terminal network interface. The monitoring terminal is used for video image encoding. It is set to self-negotiation; B. Adjust the rate of the monitoring terminal network interface according to the rate at which the monitoring terminal network interface sends video data. The solution of the invention is simple and easy to implement, has low cost, and can solve the problem of network packet loss caused by traffic burst in many cases.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a method and a device for adjusting the working mode of a network interface of a monitoring terminal. Background technique [0002] In the IP video surveillance transmission network, the transmission requirements for network equipment are quite different from the traditional requirements, mainly because the IP video surveillance data packets carried by them have their own characteristics. As we all know, IP video data packets are divided into I frames, P frames, and sometimes B frames. For the network equipment responsible for video data transmission, the situation with the largest traffic load is that the I-frame data of multiple video streams rush in at the same time. At this time, the superimposition of several I-frame data may instantly exceed the output port rate of the network device, which will cause the loss of video data packets, and the actual experience for t...
