Would it be enough to say that the page background may extend beyond the declared 'writable' area of the page, in this case? I.e. we define the page dimensions as the safe area, while allowing the background to fill the unsafe area as well?

There is such a thing as non-interlaced TV tube-based monitors, but I think they are mostly used by pros for specialized purposes (correct me if I'm wrong). So any author willing to write a special style sheet for TVs with unsafe areas is probably also going to write rules in the same style sheet to deal with flickering (by having text not too small, line thicknesses in multiples of 2px, etc.). > > > On Dec 6, 2010, at 9:04 AM, David Singer wrote: > >> But I'm surprised that web content is viewable at all on an old standard-definition CRT TV. By the time you're down to that resolution, and you've got interlace (so you have to blur horizontal lines to avoid flicker), is it usable? >> >> On Dec 6, 2010, at 2:28 , Joćo Eiras wrote: >> >>> >>>> AFAIK, you can use all of a digital display. Are we expecting web browsers to be written on devices that have this as an issue? Are there digital displays which (deliberately, I guess) do not display all the margin outside the safe area (maybe on the grounds that it's boring)? >>>> >>> >>> As I mentioned in the first e-mail on this thread "My team is working with set top boxes and other media devices which connect to TVs". So, yes :) The new web connected tvs, and media devices connected with HDMI cables have high accuracy (little to no content cropped), but when using the RCA cable, and/or an older CRT TV, the problem is quite visible. >> >> David Singer >> Multimedia and Software Standards, Apple Inc. >> >> > David Singer Multimedia and Software Standards, Apple Inc.
