Yes. I get the ANU web students to design content for TV by targeting
a business card sized QVGA screen on a PDA or smartphone. When held
in the hand, that looks about the same size as a TV on the other side
of the room <http://www.tomw.net.au/2006/wd/mobile.shtml#typical>.
An analog TV has only about the same resolution as a 320 x 240 pixel
PDA screen. So watching video on a pocket size device is no worse
than ordinary TV. I noticed this when watching highly compressed
video clips downloaded from the web on my large LCD display
<http://www.tomw.net.au/2001/sa/lcdtv.shtml>. If I sit up close using
it as a PC display, the quality of the video clips is awful. But if I
sit on the other side of the room the same video looks fine.
All this shouldn't be surprising, as analog TV was designed around
the limitations of human vision. There was no point in making the
quality any higher as the average person would not notice the
difference at normal viewing distances.
Of course this only applies if you are used to a "normal" size TV,
not a huge high definition home theatre screen. But I doubt that
this will be the normal viewing mode in the average home.
Even if a home has a wall sized screen I don't think it will be used
like a cinema most of the time, with one big screen showing one
picture. Much of the time it will look like mission control at NASA,
or an access grid screen, with lots of little windows of video and
data <http://if.anu.edu.au/SW/VP.html>.
