Details such as stones in buildings or vegetation appeared a little more blurred. A number of Christmas day tapes (see list above) seem to be original 1080/60i capture (over Philadelphia etc.) and, with a suitable display and not too much added compression, should look crisper.

With a new 65" plasma display (Panasonic TH-65VX100U), the blurring attributed above to viewing "In Focus" travelogues--whether originally captured at 24p/25p or 1080/50i/60i--on a 1080i CRT RPTV has vanished. (Developing CRT coolant contamination last year no doubt spoiled images, too.) Using this new designer/professional plasma at about 8' for ~33-degree-wide images, although 4' viewing is feasible--not comfortable--because the images are so clear and artifact-free. Typical interlace-viewing artifacts, such as 'twittering' fine details from distant buildings or rocks are gone, replaced by crisp colorful 1080/60p deinterlaced images from this series airing on HDNet.
One VX100 reviewer wrote
that the video processor in this plasma model, designed by Panny's professional division, was selected because most VP chipsets were inadequate. After hooking up the VX100 with HDMI for all-digital 18-bit processing, I found that YPbPr cables delivered ~1424 lines of maximum effective horizontal resolution from HDNet's Sat. 7:30-7:40 am ET test patterns versus ~1335 lines with HDMI, so I disconnected the HDMI. (The display resolves full 1920X1080 from sources such as signal generators.) Still exploring, as mentioned in my recent HD technical-section thread, whether this display's digital-cinema-initiative, wider-gamut color use needs correction with an external color management system. Everything added up to a spectacular new though-a-window look while viewing the "Over Greece" segment this morning. -- John
