IATSCChannelTuneRequest Interface

The IATSCChannelTuneRequest interface provides methods for tuning to a channel in an ATSC network. The ATSCChannelTuneRequest object implements this interface.

Methods

The IATSCChannelTuneRequest interface inherits from IChannelTuneRequest.

In addition, IATSCChannelTuneRequest defines 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.
