Create a custom channel

Layout example

Description

A 4x3 source and a cropped 16x9 source 
together with a background image.

To get this look:

 Upload an image 

through the Branding Content page. 
Follow the steps from the first 4x3 
example (two rows up) to add the sources 
then use the crop utility to crop the 
second source to a square aspect ratio.

Time to get started on your own layouts! See:

Create a local custom channel or layout

We call a channel a custom channel (or custom layout channel) when is has multiple sources, image elements, 
multiple layouts, or any combination of those items. Custom layouts give you full control on size and position 
of the pictures, sources and text overlays you add to your channel. 

Custom local channels use HD Encoders that have been added as sources (see 

Add an HD 

Encoder as a source (custom channel)

). Each HD Encoder used adds overhead to the 

VGA Grid Concentrator. Ensure you monitor CPU usage when using multiple HD Encoders.

Use this procedure to help you create a new channel or layout, then use the related procedures to add 
elements to your layout.

If you're planning to use live switching, we strongly recommend you rename the channel rather 
than using the default channel name (

Rename a channel

). See the note at the bottom of this 

topic to avoid streaming and recording issues resulting from adding or deleting layouts when live 
switching.

To create a new custom channel (with default layout) or add a layout to an existing channel:

 1.  Login to the Admin panel as 

admin

.  See 

Connect to the Admin panel

.

 2.  Do one of the following to make the Sources page appear:

 a.  select your channel from the channels menu and click
