public class AlternativeContentErrorEvent
extends javax.tv.service.selection.AlternativeContentEvent

AlternativeContentErrorEvent is generated to indicate that "alternative" content is being presented due to an error that prevents the presentation of normal content as part of selection of a service and during presentation of that selected service.

This event will be generated instead of SelectionFailedEvent where normal content could not be presented due to the following situations:

  • The parental control settings prevent it.
  • The CA system refusing to permit it.
  • The requested content could not be found in the network.
  • The absence of a ServiceContentHandler required to present the requested service.
  • Problems with tuning.
Such presentation failures are not considered selection failures.

This event will be generated instead of PresentationTerminatedEvent where normal content presentation could not continue due to the following situations:

  • The parental control settings prevent it.
  • The CA system refusing to permit it.
  • Inability to locate the requested content on the network.
  • The absence of a ServiceContentHandler required to present the requested service.
  • Change of tuning information.
Such presentation failures do not terminate presentation and allow for restoration of normal content presentation after correction of the error condition.
