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.

TTFN,
Mark

The 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.
