Yeah the US is a little different. For the broadcast networks with local affiliate stations (ABC, CBS, NBC, PBS, Fox, etc.), the cable or satellite provider will generally only provide you with your local affiliate. So if you live in Los Angeles, you will only get the NBC station for Los Angeles, and not for New York or San Francisco.
The cable stations (CNN, ESPN, Discovery Channel, Disney Channel, etc) have just one version. At most they might have two, an East Coast and a West Coast version with the same content, just time shifted by three hours, but normally you'll get just the one appropriate for your geographic location (though not always, Dish Network provides the East Coast feed even in Hawaii).
