| IBDA_UserActivityService::SetCurrentTunerUseReason Specifies the current tuner use reason for a Media Sink Device (MSD) in a Protected Broadcast Driver Architecture (PBDA) media graph. |
| IBDA_UserActivityService::UserActivityDetected Indicates that a Media Sink Device (MSD) in a Protected Broadcast Driver Architecture (PBDA) media graph has detected user activity and is informing a Media Transfer Device (MTD) of this activity. |
