IATSCChannelTuneRequest interface (tuner.h)

[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]

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

Inheritance

The IATSCChannelTuneRequest interface inherits from IChannelTuneRequest. IATSCChannelTuneRequest also has these types of members:

• Methods

Methods

The IATSCChannelTuneRequest interface has these methods.

IATSCChannelTuneRequest::get_MinorChannel The get_MinorChannel method gets the current minor channel.
IATSCChannelTuneRequest::put_MinorChannel The put_MinorChannel method 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

To declare the interface identifier (IID) for this interface, use the __uuidof operator: __uuidof(IATSCChannelTuneRequest).
