WinTV-CI is a USB2.0 device that provides a slot for a Conditional Access Module (CAM), which is used to decode the information from your subscription card. You should chose your CAM based on it?s compatibility with your selected subscription card, as different providers use various different encryption types; therefore requiring different CAM?s (consult your service provider and the lists below for information about compatible CAM?s).
Use the WinTV-CI with either the WinTV software provided, or with Windows Media Center* giving you the power to watch, pause, rewind and record your TV shows with the addition of ?Pay TV?, when combined with a valid subscription card and compatible CAM.
