If HD is the standard, maybe the standard definition channels should suffix SD. UHD channels are usually appropriately named.

I wonder how familiar the general public are with the term SD, as you don't see it used in many places. Up until now, any suffix on a channel name has indicated there's something special about it, over and above those without. If a load of channels are suddenly labelled 'SD' I could see some people thinking they're in 'Super Definition' or something like that.

It would be quite nice to lose the HD suffix from the EPGs though, because, as we've seen with the BBC One regional HD rollout, you do end up with some rather garbled channel names in order to fit in an extra two or three characters.
