DVD player deinterlaces videos?

[elmuz]

Hi all,
yesterday people asked me why dvd videos look "deinterlaced" (even in case they are interlaced content) when played on their stand alone player... while through computer players you see combs...
Who is responsible of that? DVD player?

The TV does it, generally. Even today, a lot of broadcast TV is interlaced, so the TV has to be able to deinterlace the source regardless of where it comes from. On older (CRT) TVs, the display itself is interlaced, so no deinterlacing happens at all - and you still don't see the combing.

1) ...so in CRT displays no chance of taking advantages from a progressive scan player, right?
2) Can we say that 100% of LCD/LED/Plasma displays can deinterlace?

1. Some can. Better CRTs will happily handle progressive input over component cables.

2. No. Many cheaper, smaller LCD TVs are little more than glorified computer monitors that have very little in the way of TV processing. They will not deinterlace, or will not deinterlace well.

I expected that... like the ones you see in professional tv studios, thicker than wider...

Never saw that capability in spec list...

Thank you for you answers...
