What set-top box(es) do I need to receive high definition iO?
The Scientific Atlanta SA4200HD is the official high definition box. It provides component video out (as well as lower-quality signals). The Sony DHG-M55CV is capable of receiving a high definition signal and sending it out the IEEE 1394 port, however, Cablevision has had problems with this in some areas, and support is spotty (its at the level of well, as long as it doesnt break anything else). There are not presently any solutions from Cablevision that provide DVI/HDMI or official <> href=”#_What_is_1394/Firewire?”>IEEE 1394 output, although there are plans to offer them sometime in the future (no specific timetable has been given).
