Video monitoring method, video monitoring server and encoder equipment

Abstract

The invention provides a video monitoring method, a video monitoring server and an encoder equipment; the video monitoring method comprises the following steps that a video monitoring client terminal sends a request message to the video monitoring server; the request message contains an encoder passage information and corresponding operation information; the operation information is opening monitoring or closing monitoring; the video monitoring server generates a control message according to the request message; the control message contains an encoder passage information and corresponding operation information and the video monitoring server sends the control message to a first multicasting group; the encoder passage is added to the first multicasting group; after the control message is received, if the control message contains the encoder passage, when the corresponding operation information is opening monitoring, the video data is sent to the video monitoring client terminal; when the corresponding operation information is closing monitoring, the video data is stopped to be sent to the video monitoring client terminal. The method, the server and the equipment can effectively reduce the load pressure of the video monitoring server and the encoder passage.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video monitoring method, a video monitoring server and an encoder device. Background technique [0002] Due to its authenticity, reliability, and universality, video surveillance technology has been widely used and developed rapidly in industries such as security, transportation, finance, and education. With the wide application of video surveillance systems, users have more and more urgent needs for camera group management and synchronous viewing. Camera grouping, as the name implies, is to add multiple cameras with the same monitoring attributes (such as geographic attributes, monitoring correlation, etc.) to a group. The advantage of camera grouping is that it can realize unified management, unified control and unified viewing of associated cameras. [0003] In the actual application of the current video surveillance system, multiple cameras are usually arranged a...

Problems solved by technology

However, the video surveillance server still needs to establish the connection between the video client and each encoder channel one by one, which increases the load pressure on the video surveillance server

[0009] In addition, the encoder channel can send unicast stream or multicast stream to the video surveillance client. Compared with sending unicast stream, sending multicast stream can greatly improve In order to reduce the bandwidth pressure on the encoder channel, but in the current implementation, a multicast address is assigned to each encoder channel, which will occupy a large number of multicast addresses for large-scale monitoring networks

Moreover, the video surveillance client needs to send multicast join messages to the multicast groups corresponding to the multicast addresses of multiple camera channels, which increases the load pressure on the video surveillance client.
