Abstract

The invention discloses a method for monitoring the network video, comprising the following steps that: a time shifting look back request message is sent to a storage server by a client through a dispatch server; the storage server receives the time shifting look back request message and sends a time shifting media stream to the client through the dispatch server; the client receives the time shifting media stream and plays the time shifting media stream. Meanwhile, the invention also discloses a network video monitoring device, comprising a front end, a media stream managing center and the client, wherein, the media stream managing center comprises the dispatch server, the storage server and a time shifting setting module. The invention provides a user with a network video monitoring proposal which has simple operation, quick response and high work efficiency and can respond to unexpected events in time as well as does the time shifting look back according to requirements.

Description

technical field [0001] The invention belongs to the field of video monitoring, in particular to a method and device for network video monitoring. Background technique [0002] Time-shifted TV technology is a kind of cyclic storage of live TV programs for a certain period of time in the streaming media system of IPTV (Internet Protocol Television), which is convenient for viewers to watch Digital Video Broadcasting (DVB, Digital Video Broadcasting). When watching digital TV programs, you can quickly locate and watch the program at a certain point in time by pressing the pause or rewind / fast-forward keys on the remote control at any time. In the current IPTV system, as time-shifting TV technology is more and more widely used, people can selectively watch the TV programs they want to watch within a period of time after the program is broadcast, thus completely breaking the barriers of watching TV programs. Traditional habits. [0003] In the existing video monitoring system, ...
