The IMSVidFeature interface represents a feature that is available through the Video Control, such as data services or closed captioning.
The IMSVidFeature interface inherits from IMSVidDevice and adds no methods to it.
To obtain a collection of the features that are available, call the IMSVidCtl::get_FeaturesAvailable method on the Video Control. To activate a feature, create a new MSVidFeatures collection object and assign it to the Video Control by calling the IMSVidCtl::put_FeaturesActive method.
Feature objects do not implement the IMSVidDevice::get_Power or IMSVidDevice::get_Status method.
