Abstract

The invention discloses a video transfer and distribution method in video monitoring, wherein, corresponding video layers of video images which are transmitted from PU equipment and delaminated and encoded are sent to CU according to receiving ability of CU by utilization of the fact that VTDU of different video layers can be distinguished. The invention also discloses a video monitoring method, a video transfer and distribution device and a video monitoring system. The video monitoring method of the invention has no high demand on equipment characteristics and simultaneously also can well meet requirements of different bandwidth users.

Description

technical field [0001] The invention relates to a video monitoring technology, in particular to a video transfer and distribution method, a video monitoring method, a video transfer and distribution device and a video monitoring system in video monitoring realized by a wide and narrowband video monitoring system based on layered video coding. Background technique [0002] Network video surveillance service is a telecommunication service that provides users with remote collection, transmission, storage and processing of images, alarm signals and other related information based on IP network. The business system includes a monitoring front end (Peripheral Unit, referred to as PU), a central management server (Central Management Server, referred to as CMS), a video transfer and distribution unit (Video Transmit and Distribute Unit, referred to as VTDU), a network recording unit (Network Record Unit, referred to as NRU) and other components of the monitoring platform and the use...
