Creating and Managing Channels

A Channel displays a sequence of content and display images and videos, but they could also display a website or a single-page application.
This page shows creating and managing channels for Screens.
Pre-requisites :

Creating a New Channel

Once you create your project for Screens, follow the steps below to create a new Channel for a Screens project:
  1. Select the Adobe Experience Manager link (top left) and then Screens. Alternatively, you can go directly to: https://localhost:4502/screens.html/content/screens .
  2. Navigate to Screens project and click Channels .
  3. Click Create next to the plus icon in the action bar. A wizard will open ( See Channel Types for more information ).
  4. Select the template from the wizard and click Next .
  5. Enter the properties for Title and Tags , More Titles and Description , On/Off Time , and Vanity URL .
  6. Click Create and the channel is created and added to your channels folder.

Channel Types

The following template options are available while using the wizard such as:
Template option
Description
Channels Folder
Allows to create a folder to store collection of channels.
Sequence Channel
Allows to create a channel that plays the components sequentially (one by one in a slide show).
Application Channel
Allows to showcase your custom web application in Screens player.
1x1 Split Screen Channel
Allows to view the component in a single zone.
1x2 Split Screen Channel
Allows to view the assets in two zones (split horizontally).
2X1 Split Screen Channel
Allows to view the assets in two zones (split vertically).
2x2 Split Screen Channel
Allows to view the assets in four zones (split horizontally and vertically in a matrix).
2 to 3 Split Screen Channel
Allows to view the assets in two zones (split horizontally) with one of the zones being larger than the other one.
Left or Right L-Bar Split Screen Channel
Allows content authors to view different types of assets in appropriately sized zones.
The Split Screen channels split the display into multiple zones so you can play several experiences at the same time, side-by-side. The experiences can either be static assets/text or embedded sequences.
The following example shows the creation of a Sequence Channel ( ChannelOne ) for a Screens project ( DemoProject ).
You can create different zones using the template options such as 1x2, 2x2, or 2 to 3 split screen channels mentioned above.
Once you create and add content to your channel, the next step is to create a location followed by creating a display. Furthermore you need to assign that channel to a display. See the resources below at the end of the section to learn more.
