Abstract

The invention provides a video profile cut control method, device and system. The method comprises the following steps of: sending a profile cut command to a media management server by a control server to ensure that the media management server is connected with a media channel of a monitor front-end unit to be switched and a media channel of a monitor terminal after the profile cut command is received by the media management server so that the monitor front-end unit to be switched is connected with the monitor terminal via the media channels, wherein the monitor front-end unit and the monitor terminal are respectively pre-connected with the media management server; and sending a key frame request to the monitor front-end unit to be switched by the control server to ensure that the monitor front-end unit to be switched sends a key frame to the monitor terminal via the media channel of the monitor terminal after the key frame request is received by the monitor front-end unit to be switched. Through the embodiment of the invention, system performance and user experience in a video profile cut process can be improved.

Description

technical field [0001] The invention relates to network video monitoring technology, in particular to a method, device and system for video wheel cut control. Background technique [0002] In Network Video Surveillance System (NVS) services, in order to minimize the requirement on network bandwidth, H.264 is generally used to encode video data before sending. H.264 encoded data is divided into I frame and non-I frame. The I frame is also called a key frame, which is a complete frame. Through this frame data, a complete video image can be decoded. Non-I frames generally include P frames and B frames. These are called reference frames. The complete video image cannot be decoded only through this frame. It needs to refer to the previous or subsequent frames to decode correctly. [0003] In the network video surveillance business, the number of monitoring lenses is far greater than the number of monitoring screens. In most cases, monitoring users need to group the monitoring l...
