I attended the demo at IBC, and I can confirm the results.Again, I must emphasize, however, that all three signals were derived from the same 1080p camera. If you don't do that, then there is a significant sharpness advantage to 1080i acquisition over 720p acquisition.

I found Hans' full report on the web at: http://www.ebu.ch/en/technical/trev/trev_308-hdtv.pdfThe full report details how the images were obtained, compressed, and displayed. All compression was using MPEG-4 AVC.I find it very interesting that on consumer 1080p displays, 720p50 was preferred over 1080i25, even at the uncompressed bitrate.John ----- Original Message ----- From: "Hoffmann, Hans" <hoffmann@xxxxxx> To: <opendtv@xxxxxxxxxxxxx> Sent: Friday, May 04, 2007 12:36 AM Subject: [opendtv] Some results - 1080p @ 60 is Next?
