Description

Stage video monitoring system

Technical Field

The invention relates to the field of monitoring equipment, in particular to a stage video monitoring system.

Background

As is known, in the stage performance, actors, stage supervision, devices, machines, lights, sounds, multimedia, and other work categories need to monitor some pictures in real time, for example, actors need to command pictures at any time in the stage performance, and stage supervision needs to see pictures of stage front pictures, command pictures, and special points at a stage supervision station.

The existing highest performance platform, the most advanced technology, and the stage video surveillance solution also only stay on distributing video signals to 5 fixedly installed televisions through a video distributor by using a camera. As stage performances become more complex, the single system cannot meet the performance requirements, and the following disadvantages mainly exist: 1. high picture delay (much greater than the macroscopic 225ms video delay); 2. the display points are fixed (lack of flexibility, unable to meet increasingly complex stage changes and flexible actor scheduling); 3. the temporary erected flow point position cannot be well qualified for work under the influence of the wire rods, and sometimes becomes a stumbling point for switching stage scenery and mechanical actions in the performance process. Even affecting personnel safety.
