ATSCComponentType

The ATSCComponentType object represents a component type that indicates whether the audio sub stream (component) is in AC-3 format.

The ATSCComponentType object is obtained through the IComponent::get_Type method of a component object within an ATSC tune request. It may also be used as a default preferred component type on the tuning space, or the preferred type on a tune request. In this case, it is obtained through the Components collection object.
