De-interlacing, Apple's position
I know this comes a bit late, but here is an update on the de-interlacing issue.
I haven't been able to check this yet, but Apple now claims to have implemented de-interlacing in it's current hardware. The bad news is that Apple appears to have no intention of doing this for the rest of us. I found this out when I accused Apple (via their Australian operation) of breaching our Trade Practices Act on the grounds that their claims regarding DVD playback quality were patently false. Apple's response (set out in part below) was predictable. What was most disappointing, however, was their complete failure to acknowledge that this might be an issue.
Please feel free to email me at
adug_au@REMOVETHISyahoo.com (having removed the REMOVETHIS) and pass this message on to others who may be affected by this as it would be good to repudiate Apple's statement (see below) that customers don't care about interlacing.
Apple Asia's statement on Interlacing:
Commercially available DVDs are either encoded with interlaced frames
or progressive frames. Since movies on commercially available DVD are
typically made with film, which unlike video does not use interlacing,
this effect does not generally occur.
De-interlacing attempts to override interlacing on the part of the
DVD author by using compromising techniques such as blending fields,
discarding fields, motion compensation etc reduce the effect of
jagged lines. However, the compromise is that motion may not be as
smooth when played back on a television. Accordingly whether or not a
DVD author decides to encode their DVD with interlaced frames or
progressive frames is at their discretion.
For your further information, depending on the capability of the
computer, de-interlacing is an automatically-enabled feature in
Apples DVD Video Player when run on certain products including its
current release PowerMac G5, PowerBook G4 and iBook and iMac computers.
De-interlacing is also a feature of Apples digital video editing
software Final Cut Pro often used during the authoring of
DVD-Videos. During this authoring production stage is when an author
would decide what his priorities are, choosing between jagged lines
on progressive-scan monitors, or motion smoothness on televisions and
encoding the DVD accordingly.
Given the above, Apple disagrees with your suggestion that Apple has in
any way breached the Trade Practices Act in connection with the
marketing or supply of its DVD players.
