[opendtv] Re: Defining Visions: They've Done It To Us Again. . .???!!!

Boy; that one snuck up on us like a garbage truck with no muffler.

The thing that really drove HDMI was cable settop boxes, when the CE
industry was informed by MPA, etc. they weren't going to be connecting
high quality content to HD screens over unprotected digital connections.

Then the Broadcast Flag was going to require HDMI (or DVI/HDCP) output
from tuner to glass for everything but commercials, apparently.

The HD disc formats are following several years of precedent, it
shouldn't be a surprise.

Of more interest to me is that HDMI as usually implemented isn't
sufficient for the 1080P24 movies and most (film) television production
available on the new disc formats.  HDMI sources (like HD DVD-V players)
usually have to interlace the content and apply 3:2 pull down and
interlace filtering to convert to the brain dead 60 Hz 540 line
broadcast transmission standards of 50 years ago implemented in most
HDMI displays.  With the new "HD Ready" European displays that support
both 50 and 60 Hz, they'll get to enjoy 3:2 interlace judder from
progressive content also. =20

What really pisses me off is that these "raster refresh" interface
standards have nothing to do with modern display technology that will
have to try to remove the repeat fields, won't be able to put back the
lost resolution of capturing or filtering for 540 lines, and will have
to resample both spatially and temporally to update most display
technologies.  If you just send 1080P24 over the wire, the display can
handle it at the highest quality and lowest cost.  Since something like
80% of TV is produced progressively, on film, it might be good to pay
attention to that entry in the non-existent Table 3 for broadcast.  For
movie disc formats its mandatory.

PS.  Name another audio interface other than HDMI that will deliver 8
channels of uncompressed digital audio at 96kHz/24-bit.  The 40 million
audio receivers in place now can only handle 2 channel Red Book LPCM,
multichannel AC-3 at 448kHz or 640kHz, or multichannel DTS up to 1.5
Mbps over S/PDIF.  Unfortunately, there's nothing to connect HDMI to (no
AV receivers under $10K with HDMI input, approximately zero installed
base). =20

The only interface that can handle HD discs today is six analog audio
cables (same as used for DVD-Audio and SACD), and 3 three analog video
cables YPrPb.  But those are unprotected, so they are not worthy.

The article starts out...

Here's a piece of really bad news for all 10 million of us who own=20
digital television sets that are more than six months old. You won't be=20
able to watch the new high-definition DVDs in high definition unless you

buy a new TV. Whose to blame for this? Hollywood, of course.

Toshiba, the primary backer of HD DVD, one of the two competing=20
high-definition formats, let it slip during road shows in Europe and the

United States last month that the one and only high-definition output=20
from its players will be HDMI, the digital input of choice on most new=20
digital TVs. As recently as a year ago, DVI, not HDMI, was the input of=20
choice, but even TVs with that older and still copy-protected input will

not be able to watch HD DVDs in high definition.

My first questions are... Will HD-DVD (or BlueRay for that matter) ever=20
make it? Will there me the financial incentive to move towards it? Can=20
Mr./Mrs./Ms. "Average American" see the difference?

Then I ask... If it DOES succeed, who will compensate me for having=20
bought a set that does not have HDMI?

I believe there are more instances
of the abridgment of the freedom of
the people by gradual and silent
encroachments of those in power than
by violent and sudden usurpations.
