Multiple Displays; Multiple Channels - Black Box iCompel ICOMP-ICC User Manual

1.1.2 Multiple Displays

The following diagram illustrates a more fully-featured situation where a user controls several players and their screens. You
might conceive of this as a set of screens displaying sales information on the floors of a shop. In practice, the number of
players would be much higher, which is why it is desirable – and soon necessary – to add further components to the network:
You can see that certain features are the same: the user, the browser, and the network. Note now the significance of the
additional features, discussed clockwise as they appear:
Publisher – A Publisher is a system you configure to provide content to multiple players. This enables you to display
l
consistent content on several screens and means you only need update it in one place. Although some player models can
perform this role, in our context the publisher is specifically the Black Box iCOMPEL Content Commander.
Channel – A Channel refers to both the content it contains and its originating publisher. The Channel Name (in this case
l
'Channel 1') identifies the channel and is often just the name of the publisher.
Subscriber – A Subscriber is a player that you configure to accept content from a publisher. In the diagram, Channel 1
l
provides the content for all the subscriber players and their screens. Subscriber and Publisher are referred to as Roles
(the only other role is Standalone, which is the role of the player in the first diagram).
You can build on the parts already described to create a network not only of multiple displays but also of

1.1.3 Multiple Channels

When your signage network grows to a large number of players and their screens, the quantity and variety of content you need
to manage and distribute grows accordingly.
Once again, it is useful to envision the key components in a condensed and summarized form.
