Using Channel Level Activation as a Single Event Playback
Overview overview
Channel Level Activation allows the channels to switch after a particular set schedule. The single event channel replaces the main channel after a set schedule and plays for a particular time, until the main channel plays its content again.
The following example provides a solution by focusing on the following key terms:
- a main sequence channel for the global sequence
- a single event channel that runs only once at a set time
- a set schedule and priority for the single playback event that occurs inside the main sequence channel

The following section explains the creation of a single event playback inside a channel for an AEM Screens project.
Prerequisites prerequisites
Before you start implementing this functionality, make sure you have the following prerequisites ready to start implementing channel level activation:
-
Create an AEM Screens project, in this example, Channel Level Activation.
-
Create a channel as MainAdChannel under the Channels folder.
-
Create another channel as TargetedSinglePlay under the Channels folder.
-
Add relevant assets to both the channels.
The following image shows the Channel Level Activation project with MainAdChannel and TargetedSinglePlay channels in the Channels folder.
Implementation implementation
Implementing Channel Level Activation in an AEM Screens project involves three major tasks:
- Setting up Project taxonomy including Channels, Locations, and Displays
- Assigning Channels to Display
- Setting up a Schedule and Priority
Follow the steps below to implement the functionality:
-
Create a Location
Navigate to your Locations folder in your AEM Screens project and create a location as Region.
note note NOTE To learn how to create a location, see Creating and Managing Locations. -
Create Display under Location
- Navigate to Channel Level Activation > Locations > Region.
- Click Region and click + Create from the action bar.
- Click Display from the wizard and create a display titled as RegionDisplay.
-
Assign Channels to Display
For MainAdChannel:
- Navigate to Channel Level Activation > Locations > Region > RegionDisplay and click Assign Channel from the action bar.
- In the Channel Assignment dialog box, Click Reference Channel by path.
- Click the Channel Path, then click Channel Level Activation > Channels > MainAdChannel.
- The Channel Role is populated as mainadchannel.
- Click the Priority and set to 1.
- Click the Supported Events such as Initial Load and Idle Screen.
- Click Save.
note note NOTE You can also assign the channel from the display dashboard. Navigate to Channel Level Activation > Locations > Region > RegionDisplay. On the action bar, select Dashboard. From the ASSIGNED CHANNELS & SCHEDULES panel, click + Assign Channel. Similarly, assign channel TargetedSinglePlay for display**:
- Navigate to Channel Level Activation > Locations > Region > RegionDisplay and click Assign Channel from the action bar.
- In the Channel Assignment dialog box, click Reference Channel by path.
- Click the Channel Path, then click Channel Level Activation > Channels > TargetedSinglePlay.
- The Channel Role is populated as targetedsingleplay.
- Set the Priority to 2.
- Click the Supported Events, and set Initial Load, Idle Screen, and Timer, as shown in the figure below.
- In active from, set as November 27, 2018, 11:59 P.M., and in active until, set as November 28, 2018, 12:05 A.M.
- Click Save.
note caution CAUTION Set the priority for the TargetedSinglePlay channel higher than the MainAdSegment channel. 
note note NOTE To choose the same day, click the next day, then manually edit the date to the same day but for a later time. Doing so restricts the user from selecting a past date. See the following example: 
Viewing the Results viewing-the-results
When you have the setup for channels and display complete, launch the AEM Screens Player to view the content.
The player displays the content of MainAdChannel and exactly at 11:59 P.M. (as set in the schedule), the TargetedSinglePlay channel displays its content until 12:05 A.M. and then the MainAdChannel resumes playing its content again.
Handling Recurrence for Assets in a Channel handling-recurrence-in-assets
You can schedule assets in a channel to recur at certain intervals on a daily, weekly, or monthly basis as per your requirement.
Suppose you want to display the contents of a channel only on Fridays from 1:00 P.M. until 10:00 P.M… You can use the Activation tab to set the desired recurring interval for your asset.
