Chapter 20 Use Channels to Play Rich Media
Concepts
Note You can trigger an emergency state on any DMP group. When a DMP group is in its emergency state, it plays emeregency
messages instead of the channel events that it is subscribed to play. A declared emergency in progress will always override channel
content on emergency-affected DMPs.

C
channel
An endpoint-subscribable calendar and package of rich media programming for digital signs. Its central
purpose is to support narrowcast messaging that engages a niche audience — to create experiences in
place.
channel event
A time-limited activity, shared in common among the endpoints that subscribe to a channel. In most
cases, an event tells your subscribed endpoints when to render rich media on your digital signs.
However, you could just as easily create an event that serves some other purpose entirely — for
example, activating endpoint NTP support or deactivating HDMI autodetection. The timing of an event
at any given location is contingent upon its host channel’s time basis.
•
Some events will play just one asset at a time. This kind of daypart might render just a live TV feed
or an animated logo, for example.
•
Other events will overlay multiple assets for simultaneous playback. This kind of daypart might
combine a live video stream with corporate branding, scrolling text, and widgets, for example.
•
A third kind of event will intersperse the other two kinds.In any case, your programming decisions
for a channel and its events will shape the channel’s personality, purpose, and scope.
D
default content
Content that your digital signs should play as needed, without any predefined schedule and without any
manual intervention. In many cases, this playback is partial and fleeting because the only purpose of
default content is to prevent noticeable playback gaps between more strategically significant assets.
Your default content plays in a continuous loop until other content starts to play.
P
play now
Content that your digital signs should start playing instantaneously when you submit the command to
start. Playback of this content continues until, at your discretion, one of the following occurs.
•
You stop playback manually.
•
Playback stops at a date and time that you set.
•
The next scheduled event begins.
