A: Clear QAM (e.g. unencrypted digital cable): Yes, InfiniTV supports Clear QAM channels; however, Windows Media Center requires that you have a CableCARD inserted in your InfiniTV device in order to configure the tuners in Media Center. Once your InfiniTV is paired and activated with your local cable system, then you can remove the CableCARD if you wish to receive ClearQAM channels only.

ATSC (e.g. over-the-air digital broadcast): InfiniTV is designed for digital cable and does not support over-the-air ATSC broadcasts. Low-cost ATSC TV tuners are available from a number of manufacturers. You can install InfiniTV tuners as well as ATSC and/or analog tuners on the same PC.

Analog: As with ATSC above, InfiniTV does not support analog TV channels. Most cable operators simulcast the analog channels in digital also, so it is likely that you will continue to receive all analog channels even through the InfiniTV is a digital-only tuner. If not, low-cost analog TV tuners are also available from a number of manufacturers. You can install InfiniTV tuners as well as analog tuners on the same PC.
