IATSCChannelTuneRequest Interface
The IATSCChannelTuneRequest interface provides methods for tuning to a channel in an ATSC network. The ATSCChannelTuneRequest object implements this interface.
In addition to the methods inherited from IChannelTuneRequest, 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. |
Remarks
ATSC defines a tune request in terms of a major channel and a minor channel. The major channel is mapped to a physical frequency and the minor channel identifies different programs within the same major channel. To access the channel numbers, use the following methods:
- Major channel: IChannelTuneRequest::get_Channel, IChannelTuneRequest::put_Channel.
- Minor channel: IATSCChannelTuneRequest::get_MinorChannel, IATSCChannelTuneRequest::put_MinorChannel.
