IChannelTuneRequest Interface

The IChannelTuneRequest interface is implemented on ChannelTuneRequest objects, which are specific to analog TV. This interface enables a guide store loader running on Microsoft® Windows® XP Home Edition or Windows XP Professional to create tune requests for analog TV networks, which an application can then pass to the Video Control. The Video Control examines all tune requests it receives. If it is an analog tune request, then the Video Control will create a WDM Analog TV Filter Graph that can play the specified channel. Applications running on earlier versions of Windows are responsible for creating their own analog graphs if the user selects a program on an analog channel. Downlevel applications should never pass an analog tune request to a BDA tuning device because the device will not be able to interpret it.

In addition to the methods inherited from IDispatch and ITuneRequest, the IChannelTuneRequest interface exposes the following methods.
