Abstract

The invention discloses a method, a system and a decoder for switching a monitoring channel. The method adopts at least one decoder, and each decoder is directly connected with a keyboard to receive information from the keyboard. The method comprises the following steps of: storing imported DVR channel information and imported decoder channel information into each decoder respectively; receiving switching control instructions from the keyboard, and searching the DVR channel information and the decoder channel information according to a DVR channel digital number and a decoder channel digital number respectively to acquire DVR channel identifier information and practical output channel number of the decoder; and setting parameters corresponding to the searched DVR channel identifier information into the corresponding parameters of a practical output channel of the decoder, and updating the configuration parameters of the decoder so as to realize switch of the monitoring channel. The method, the system and the decoder solve the problems of high cost, complex implementation, insufficiently flexible operation and poor expandability in the prior art.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a method, system and decoder for switching monitoring channels. Background technique [0002] There are many digital hard disk video recorders (DVR) and monitoring points in a monitoring system, but the monitors and decoders configured in the monitoring center are limited, and it is impossible to realize one-to-one display and monitoring, that is, the number of display devices in the monitoring center will be far away. less than the number of monitoring points. [0003] In the prior art, when manipulating the decoder to control the video wall, it is usually realized by configuring an analog matrix. Specifically, the DVR digital coding channel is converted into an analog channel through a decoder, and then all the analog video signals on the analog channel are connected to the analog matrix, and by operating the analog matrix, different DVR digital coding channels are di...
