Digital "subchannels" in the U.S. are also equal. ("subchannel" is a poor choice of words, but nothing has really come along to take its place)
I think it's more a misuse of the word "subchannel" in this forum. Many people seem to believe that ".1" is the primary channel while ".2, .3, etc." are subchannels. All are subchannels. The only advantage that a .1 subchannel would have is that if you tune your television to a channel number, say channel 8, you would get channel 8.1 by default. It's also common practice to place the best programming stream on .1, but it's not universal practice. For example, if a station broadcasts a HD feed and two SD feeds, the HD feed usually goes on .1, and if a station has a major network (ABC, CBS, Fox, NBC, PBS), that usually goes on .1, while minor networks (MyNetworkTV, The CW, ThisTV, RTV, etc.) generally go on .2, .3, etc.
The FCC refers to major channel numbers ( 8 ) and minor channel numbers (1, 2, 3, etc.), giving you 8.1, 8.2, 8.3, etc.
