It is not a message from the Emergency Alert System (EAS). It's a colorful message displayed on your TV, right? EAS messages are crudely monochrome.
I occasionally get those messages. It reads, "Get This Service Now...To Subscribe to This Channel TBS...Call (866) 123-4567..."
From what I understand, it the default screen when your cable box syncs with the headend at Cox. It is annoying. I've never waited 30-60 seconds for it to clear. That's a long time. Mine disappears within 10 seconds or so.
It's interesting the cable box displays a code during the sync. I'll have to look for that next time.
