Out here in Southern California, some of the games of the Anaheim Ducks of the NHL are shown on a small, independent UHF station in Orange County called KDOC. It gets a good placement on my cable system (channel 10), although it’s really channel 56 if you get it over the air.
Anyway, when KDOC shows hockey games, they seem to have a lot of trouble showing the ice. The ice is so bright that you can’t see the players very well in the center of the ice, especially those wearing white sweaters.
Is this likely a problem of the way the station is transmitted to my cable provider or does KDOC just have cheap equipment. When the Ducks games are on the local Fox Sports network, they look fine.
Usually, the problem is that the cable company hasn’t matched the various channels properly in terms of brightness etc. before modulating them on to the cable.
Or it can be a fault on the equipment used to receive the channel and feed it to the cable. Excessive brightness on one channel can be due to a missing termination on the baseband vision feed. It’s unlikely to be caused by anything that happens at UHF frequencies. You can get standing waves on a cable at UHF, but that is more likely to manifest itself as grainy pictures on some channels.
