The ITuner interface is implemented on the Microsoft BDA Network Provider filters. It provides methods for passing tune requests down to the hardware device and receiving current tuning settings. Generally, applications should use the derived interface IScanningTuner instead of ITuner.
Note Only applications that are intended to run on Microsoft® Windows® 9.x or Windows 2000 will use this interface. On Windows XP, the Video Control handles all tuning interactions with the Network Provider.
Methods
The ITuner interface inherits the methods of the IUnknown interface.
In addition, ITuner defines the following methods.
