Calculating required disk space

Most digital media content, with the exception of video files, does not require large amounts of storage. If your Layouts do

not include any video files, then a disk space allowance of 1GB to 2GB should be sufficient.

If your Layouts include video files, you must increase this allowance by at least 2GB per hour of standard quality video.

Higher quality video may require even more disk space.

You can see the size on the Status page of the Publisher iCOMPEL after publishing. A Subscriber iCOMPEL requires at

least twice the disk space because it stores the Channel twice - once for subscribing purposes and again for displaying.

7.3.2 Publishing a Channel

Once the Channel role is set to Publish; the iCOMPEL is configured accordingly, and the Schedule is satisfactory,

you are ready to begin publishing. Click on Channels in the Menu bar, and go to Publish Channel. This will take you to

the following page:

The publish tab

If you are publishing to a USB memory stick, then you will need to insert that into the iCOMPEL before you click the

publish button. You can simply press Publish Channel Now to begin the publish process or you can set a time in the

future to activate this channel.

Alternatively, you could use the Activate after option. This will immediately start the Channel publishing as per the

Activate as soon as possible option, but the subscribers will not show the updated channel contents until the chosen

date. Activate after is useful to ensure that all the subscribers start showing the Channel content at the same time rather

than as soon as they can copy it across. A slow network with many large media files in the channel could lead to a large

difference in when each subscriber completes downloading the Channel content.

The Publishing Process

What happens next depends on how the Publisher is configured:

To an iCOMPEL or External Server

If the Publisher is configured to publish the Channel to itself or an external FTP site, then the copying process will begin. A

progress bar will be displayed showing how much of the upload is complete. The next time the subscribing iCOMPEL

players check the Channel, they will download the Channel contents.
