[SBE] DTV image freeze alarm

[Gibson Prichard]

I'm not sure I get the criteria, Henry. What sort of frame sync passes 
8VSB or ASI? Frame Synchronizers are use to time video to a house 
standard and don't process ASI or certainly not 8VSB. If you're looking 
to detect frozen video from a tuner, there are numerous devices that 
will do that, from multi-viewers with SNMP monitoring to simple video 
freeze alarms with contact closures. If you want a tuner with built-in 
freeze-frame detection (and presumably loss of carrier detection), 
someone like Sencore comes to mind.
FM Systems makes a card that will detect frozen video and switch to 
another feed, as well give an alarm contact of freeze status. Presumably 
something you already have can alert you.

Best of luck.
