Another similar wrinkle is that some channels have different on air
hours on different platforms, e.g. they can be on 24hrs on Cable but
share space on Freeview, i.e. the kids channels go off air at 1900 and
some shopping channel or other starts broadcasting.

I think myth has some concept of the same channel arriving via
different sources, I'm not sure but I think it is based on the channel
name field being the same. I only have Freeview so I haven't had to
figure out exactly what goes on, I've been toying with adding a
FreeviewHD tuner to my existing set of Freeview ones -- so I guess I
would end up with a related problem at that point.

sd_json seems to do caching and only pulls in new data, so two back to
back calls ought to have low additional overhead compared to a single
call, maybe?
