The subscription channel sponsors the trophy and, as such, will show all four of this week’s games as the eight remaining teams play for a place at Hampden.
Dundee and Glasgow are the host cities on both nights with a game in each on both Wednesday and Thursday.
First, Rangers host Livingston at Ibrox which will be shown on Premier Sports 1, while Dundee host the cup holders St Johnstone.
Some 24hours later the semi-finalists will be complete as Celtic host Raith Rovers, again on PS1 and Hibs travel to Tannadice to take on Dundee United.
The match officials for each game have been appointed – here’s the referee who is behind the whistle for each game this week.
