The 2.7.0 version added a mechanism for controlling the output of graphics that allows you to:
Activation of the Graphics List feature is done by toggling the AirManager→Menu File→Configure→Services→Broadcast servers→GrCtl
option for the selected program channel:
AirManager→Menu Window→Graphics→Channel Name
,After activating the Graphics List function, it is possible to use the Graphics window for the corresponding program channel. The Graphics window is visually similar to the Broadcast window which provides playlist management but initially it fulfills a different role and has a number of functional differences:
The Graphics window supports autogeneration of secondary events allowing you to set up flexible custom graphics playout conditions.
The Graphics control list supports control using the action mechanism:
Executable | Parameters | Description |
---|---|---|
Start graphics group |
| The Start graphics group action fires the first event in the group |
Stop graphics group | The action accepts one parameter:
| The Stop graphics group action stops all active events with the specified group. |
The screenshot is an example of graphics event distribution for the case when the simple_lower_third event from Graphics CAST1 line 1 is manually triggered. The Player column for this event is set to 2, so the simple_lower_third clip is sent to CAST1_LAY2 for playback.
Five seconds after playback starts, a secondary event configured for simple_lower_third is triggered, which triggers the first element of the gr2 group. This is possible because of a preconfigured program channel action that monitors the GR_START value in the Player column of the secondary event and executes a “Start graphics group” action with the group name gr2.
In turn, the system finds the first element with a group value equal to gr2 and then starts it for playback in the corresponding graphics layer (CAST1_LAY4, since Player=4).
