The provider definition is the template that decides the properties for a channel. However, the display profile channel definition ultimately decides the values for the channel attributes. The display profile channel definition can define properties that overwrite the properties defined by the provider definition.
Container channels are channels that primarily generate its content by aggregating the content of other (its child) channels. A container channel allows for available and selected channel lists (see “Available and Selected List” on page 49) and can contain leaf channel definitions.
Both container and leaf channel properties can be configured from the administration console. See the provider-specific display profile properties for more information on the channel properties.
