Rundown

Playlists, preview and program — the operator's running order.

Taking, previewing and the tallies.

Two mini monitors sit above the list, each naming the rows it shows. PGM, in red, is what is on air. PVW, in green, is program as it will look after the next take: the row Start takes while nothing is on air, then the row Next takes, or End of playlist when Next has nowhere to go. PVW shows that row at rest, without playing its animations. Each row carries a pair of tallies: PVW for the row in preview, PGM for a row on air.
