[opendtv] Re: News: If There's a High-Definition TV in Your Future, Wait Till

A good progressive DVD player has access to the MPEG-2 repeat flags to help put fields back together to make progressive frames. While these are not completely reliable they still furnish information to the process that a TV deinterlacer does not have. So for progressive telecined material my money is still on the player.

Why do you assume that one method must be better than the other? There's
no guarantee that the DVD player can deinterlace better than the
display. If the interface from DVD to display is component video, which
can be either progressive or interlaced, then the final image quality
will not necessarily be better from a progressive DVD player output.



The main point i was trying to make by posting the article
and comment is that the Average Consumer who buys an HD
capable display will have little use for one of the HD
disc formats.



I know that was your point, and has been for some time. My take on this
is that DVDs are "good enough," even though a screen of around 40" can
show improvement with better source material that regular DVD.

The 10 Mb/s peak bandwidth of DVDs makes them about the same as ED, if
properly deinterlaced. So, "good enough," IMO, which doesn't mean it
couldn't be better.



For what it is worth, I am happy to let the broadcasters
waste their bandwidth on 720P. It is in the world of
downloaded content that 480/576P will get a strong
foothold. The 480 x 320 stuff on my iPhone looks
outstanding.



That's neither here nor there. Low quality sound on a telephone or cell
phone does not mean that there's no reason to pursue high quality audio
in other appliances. Low quality video in cell phone or PC applications
does not mean that low quality video is all we should pursue either.
