Digiatl Video Backup Switcher


To ensure a safely broadcasting and automatic playout, main and backup signals transmission at the same time via multiple methods and paths is the necessary guarantee for TV stations.

SLDSW Video Backup Switchers can automatically detect multiple video signals, take prompt reaction, and switch backup signals accurately under situations like system fault (even when there is only sync signals without image), it ensures a continuous smooth transmission . As a Backup & Emergency device, it has been successfully proved efficient in the technical test and live application in editing, broadcasting, monitoring and transmission part of radio stations, security centers, traffic systems, etc.

 


     



Main Features:

Compatible with HD/SD-SDI, Choose by menu.

4 CH SD/HD-SDI inputs, distribute each CH to 4 outputs.

CH1 with bypass of input and output.

Automatic switch between main and backup signals based on intelligent detecting system. Any channels can be manually assigned as backup. Switch back to main when main signal turns to normal. Parallel and effective control automatically and manually. Priority: CH1 CH2 CH3 CH4.

Time and sensitivity threshold adjustable of black, frame still detecting.

Time correction of input, avoid jitter and distortion when switching.

With external REF port, for time synchronization.

Optional Auto and Manual mode operation.

Support light & sound alarm of CH 1, indicator lights on for normal transmission, flickering for abnormal.
