If you've lost one second, 6 times in six months, that is like *six* nines for
the year; already 10 times better than most commercial services (it's about 
6.5 nines, actually:

https://www.bmc.com/blogs/service-availability-calculation-metrics/

That's already, likely, *much* better than they're paying for.  Pushing to
seven nines will cost about ten times what they're paying now.

This is what we used to call a "Sales problem", in my IT work; the problem is not
that the service is bad, the problem is that the customer doesn't have reasonable
expectation, because it's not been explained to them what service levels are,
and how much it costs to add each "nine" at the end of that measure.

I know this won't help, but I hope this helps.  :-)

Your problem is worse, because if your outage is only 1 second, you have to guarantee
that any duplicate presented streams are in sync to no less than 9/10 of that, 100ms 
or less.

Can you just turn the buffering up a second?
