The IATSCChannelTuneRequest interface is implemented on the ATSCChannelTuneRequest object and provides methods for getting and setting the minor channel for an ATSC transmission. The major channel is accessed using the get_Channel and put_Channel methods inherited from the IChannelTuneRequest interface, and the physical channel is accessed through the IATSCLocator interface.
In addition to the methods inherited from IChannelTuneRequest interface, the IATSCChannelTuneRequest interface exposes the following methods.
| Method | Description |
| get_MinorChannel | Gets the current minor channel. |
| put_MinorChannel | Sets the minor channel to be tuned. |
