Hey,
I recently installed a video system in a casino's poker room. The system consists of these BMD components:
In Rack
Smart VideoHub 40x40
10 12G Teranex Mini Analog to SDI converters
7 12G Teranex Mini HDMI to SDI converters (7 PCs feeding signal from nearby)
Network Switch (providing some PoE power to Teranex)
Furman (for power)
10 DirecTV receivers outputting through component cables with RCA -> BNC adapters on them
Endpoint
BlackmagicDesign SDI to HDMI microconverters outputting through HDMI to TVs
Using iPad and videohub control app for control over the local network
The Problem
The analog to SDI sources (which are the DirecTV receivers) all randomly blackout at different times on different destinations. They will often occur seconds to minutes from each other.
Example, if TV1 is sourced from DTV1, and so are TVs 2-10, TV1 may suffer a blackout and moments later TV8 will suffer a blackout. Same source, different blackout times.
During the blackouts, the lock light on the microconverter endpoints does go away, indicating a loss of signal from the rack. It is perplexing, however, since the same source signal is being fed to the videohub, just coming out different outputs.
After checking all connections and finding nothing wrong, we decided perhaps heat was the issue and added more fans than we could find room for. The problem persists.
Anyone have any idea on what might be causing this particular "rolling" random blackouts?
