http://www.homecinemachoice.com/cgi-bin/shownews.php?id=7606 WHAT KIND OF TV SET WILL YOU NEED TO RECEIVE SKY'S HDTV SERVICE? * Any kind of screen or TV set could be connected to Sky's HD STB but, to truly experience Sky's HDTV picture quality, customers will need a 26" or larger "HD Ready" plasma, LCD or DLP TV. Seems to suggest some downconverting is in place, maybe? WHAT FORMAT WILL SKY'S HDTV SYSTEM USE? * Sky 's HDTV broadcasting system and HDTV receiver will support two HDTV formats: 720 / P / 50 (Progressively Scanned picture) and 1080 / I / 25 (Interlaced picture) Interesting.... HOW WILL SKY'S HDTV RECEIVER CONNECT TO THE TV DISPLAY? * The receiver will have an HDMI connector (High Definition Multimedia Interface) as its primary means of connecting to an HD display. HDMI can also be connected to DVI equipped displays using a suitable adapter cable. * Most HDTV content will be protected by HDCP (High-bandwidth Digital Content Protection). This means most HDTV content will only be able to be viewed on display devices that have HDCP software built into them.
