You noticed that too, eh?
Actually, this morning around 9 or so, somebody was working on the display. I saw the computer desktop and they were playing with the display drivers for the VIPIR radar. I noticed around my lunch at 3 or so, that it was still the same image we were used to, but tonight it is dimmer.
My understanding is that stations that mulitcast sometimes re-encode their second channel so that it doesn't need as much bandwith thus preserving that for the main channel. I believe Ken12 has made reference to this when I've asked about how ABC 11 in RDU has 3 channels when ABC News Now was going plus the primary HD and tertiary local newschannel.
If you noticed on the VIPIR display prior to tonight there was a lot of artifacting when the met was zooming in to a particular area or when 9 was looping the display. I never noticed if affecting 9.1. However, I am not seeing the artifacting on 9.2 now.
My belief is that they are re-encoding or compressing 9.2 for a smoother image with little to no effect on 9.1. Makes that Eyewitness News 9 Newschannel that's coming sound a little closer than we may have initially thought.
But like most things, we shall see...
