Before you can delete a device channel, you must first delete that channel from that channel
from any channel groups or delete the channel group(s) that use the channel.
Setting up Channel Groups
A channel group is a cluster configured with one or more device channels composed from
compatible video servers or character generators. Many channel groups can be created from
the same pool of resources, and different groups can use the same resources to serve
different operational needs.

Each channel group must contain a single “type” of device. For instance, a channel group
called AS is a grouping of channels from two or more AirSpeed video servers, while a
different channel group named CG is a grouping of channels on a Deko character generator.
AirSpeed channels provide one of the best examples of the way in which channel groups
provide control configurations; they do not guarantee media availability, which is the role of
the AirSpeed studio configuration. For example, a station has two AirSpeed video servers,
each with two channels that are numbered 2 and 3. (With AirSpeed video servers, the first
channel is reserved for ingest.) Let’s call the first AirSpeed AS1 and the second AS2. With
channel groups on Command, the station’s system administrator can set up numerous
different channel groups and call them anything, such as:
