The ICARequest object represents an attempt by the user to access a service. When the user tunes to a channel, a tune request is generated in the form of an ITuneRequest object. The Conditional Access (CA) Manager creates an ICARequest object to encapsulate the tune request. The CA Manager has a maximum of one active request at a time.
A request can have one or more components, which represent different streams within the same request. Components include audio streams, video streams, and auxiliary data streams. To retrieve the components in a request, retrieve the ICARequest.Components property. For more information about components, see ICAComponent.
