Right now, We have BBC1, BBC2, Scottish/Grampian/Border, C4 and Five. If Britian never existed and it was just the 4 countries (Scotland, England, Ireland (It was one whole country until the 1910's), Wales) since Queen Elisabeth I died in 1603, This is how Scotland might have in their channels
SBC1 (Scottish Broadcasting Corporation)
SBC2
STV Central (or STV North in Northen Scotland and STV South in Southern Scotland)
C4S (Channel 4 Scotland)
G5 (Gaelic Channel 5)

EBC1 (English Broadcasting Corporation)
EBC2
