A tuner object provides an interface to control tuner hardware. A tuner could be FM radio, cable TV, or RF (over-the- air) TV. The abstraction could also be used to create an object to "tune" digital radio and TV broadcasts from the network. In general, objects that inherit from the tuner class control the tuning process itself. Other objects must be used to actually see the images being tuned and/or control the audio being tuned.
UMS supplies two device objects that inherit from the UMSTuner class and can be instantiated: UMSRadioTuner and UMSTVTuner.
