Channel Level Activation - Single Event Playback

Using Channel Level Activation covers the following topics:

Overview

Channel Level Activation allows the channels to switch after a particluar 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

Using Channel Level Activation

The following section explains the creation of a single event playback inside a channel for an AEM Screens project.

Prerequisites

Before you start implementing this functionality, please 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 Channels folder
  • Create another channel as TargetedSinglePlay under Channels folder
  • Add relevant assets to both the channels
The following image shows the Channel Level Activation project with MainAdChannel and TargetedSinglePlay channels in Channels folder.
For additional information on how to create a project and how to create a sequence channel, please refer to resources below:

Implementation

Implementing Channel Level Activation in an AEM Screens project involves three major tasks:
  1. Setting up Project taxonomy including Channels, Locations, and Displays
  2. Assigning Channels to Display
  3. Setting up a Schedule and Priority

    To learn how to create a location, please refer to Creating and Managing Locations .
  2. Create Display under Location
    1. Navigate to Channel Level Activation > Locations > Region .
    2. Select Region and click + Create from the action bar.

Viewing the Results

Once you have the set up for channels and display complete, please launch the AEM Screens player to view the content.
The player displays the content of MainAdChannel and exactly at 11:59 pm (as set in the schedule), the TargetedSinglePlay channel will display its content until 12:05 am and then the MainAdChannel will resume playing its content again.
