Broadcasts
The broadcasts section by default shows a list of future broadcast dates. The green badge on the right top of the table, indicates the episode playing next.
When clicking the Past tab, you get a list of the past broadcast dates which already aired.
Use the Date Filter in the table header to specify the From date for listing broadcasts.
Use the pagination controls in the table footer to navigate through additional records. To adjust the number of entries displayed, enter a value in the Dates per page input field.

The Length column in the table displays the duration of the timeslot, while the Media Sources column provides details on:
Actual length of the media source: The total duration of all assigned media sources.
Type of media source: Displays

if multiple types are assigned.Missing media source warning: A warning badge labeled

orToo long
if the media source does not fit the timeslot.

Example of a media source exceeding the timeslot duration.

Broadcast dates without assigned episodes are provided with a assign episode button. Click this button to either create a new episode or select one of the existing episodes.

Assign existing episode
Press the button with the downwards arrow to assign an existing episode to the given broadcast date.

Assign episode to multiple dates (re-broadcasts)
You are even allowed to assign one episode to multiple broadcast dates. A common use case is to perform re-broadcasts of some episodes. In such case the media sources of only the first broadcast date is relevant. All subsequent broadcasts are performed on the actual recording of the first broadcast.
After some episode has multiple broadcast dates, they are marked with a repetition icon.

The screenshot above shows an episode assigned to two broadcast dates. The second entry is a repetition of the first broadcast. In that example the play-out will use the recording of the broadcast on 23rd December for the broadcast on the 24th December.
