IComponent Interface

The IComponent interface a base class for all derived interfaces such as IMPEG2Component and it describes the general characteristics of a component, which is an elementary stream within the program stream. The derived interfaces describe the properties of a component that are specific to a given network type. Component objects are created and attached to the tune request by the BDA Transport Information Filter (TIF) after reception has begun. All component objects also support IPersistPropertyBag.

In addition to the methods inherited from IDispatch, the IComponent interface exposes the following methods.

get_DescLangID Retrieves the language for presentation of the description.
get_Description Retrieves the description of the component.
get_Status Retrieves the requested or actual status of the component.
