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

You are pretty close regarding unprotected analog and digital outputs
(including VGA) being grandfathered for some period of time at some down
res'd number of pixels corresponding to a few hundred lines.

[RH]" I'm also concerned whether they are going to enforce encryption in
order to play back the hi-rez Surround Sound tracks.  That would force
most of us to buy a new Surround Sound Receiver that has an HDMI sound
interface.  [Bye, Bye DD Optical and Coax.]"

S/PDIF is bye, bye for reasons other than encryption.  It will only pass
a couple of what are now Legacy codecs (DD and DTS+) and 2 channel PCM.


HD disc players decode and mix 7.1 channels of high quality PCM or
packed PCM, newer versions of DD+ and DTS+HD (lossy and lossless), and
newer high efficiency codecs optimize for download and streaming
efficiency.  Once those signals are decoded, channel mapped, mixed,
etc.; it is painful but possible to re-compress the PCM result into 5.1
ch 448kHz or 640kHz DD or 1.5 Mbps DTS+ to output to 40 million existing
AVRs over S/PDIF. =20

The copy protection related sunset for S/PDIF just came and went (was
extended), so who knows when it will really go dark (not until something
takes its place is my guess). Yes, an HDMI audio receiver is probably in
your future.

I also believe this story has been mis-reported.
Presuming that the HD-DVD/Blu-Ray Players would follow the lead of
current Upconverting
DVD Players (lo-rez only via Component Video and hi-rez only via HDCP
covered DVI/HDMI),
I would expect the following: =20
=20
1. The HDMI port would only work with HDCP compliant DVI and HDMI ports
for hi-rez.
2. Since most current HDTVs will only accept 480p/720p/1080i, the HDMI
port should
        selectively down convert anything that is higher than this (e.g.
1080p).
3. HDTV's with non-HDCP compliant DVI ports would only work lo-rez (if
at all).
             [That's why I insisted my HDTV had a HDCP capable DVI
port.]
             [Sorry Charlie, if yours doesn't do HDCP correctly.]
4. Component Video interface would only work at lo-rez (if any are even
allowed).
             [Sorry Charlie, if yours doesn't have DVI/HDCP or HDMI.]
             [At least you can still watch lo-rez DVD's and HD
Television.]
=20
I'm also concerned whether they are going to enforce encryption in order
to play back the hi-rez Surround Sound tracks.  That would force most of
us to buy a new Surround Sound Receiver that has an HDMI sound
interface.  [Bye, Bye DD Optical and Coax.]

HDMI Spec seems to indicate that up to 8 channels of 192 kSps Audio can
be supported concurrently with the highest resolution/refresh setting of
1920x1080p at 60 Hz.
This seems to be within the 165 Mpixel/sec limit of a Type A HDMI
(Single Channel) interface.
So why is a Type B HDMI (Dual Channel) interface included in the HDMI
spec if it is never needed????
Under what conditions would we be surprised (again!!!), forcing yet
another upgrade to a Dual Channel capable system???
=20
Of course, we won't actually know until we see these players from a
variety of suppliers.
=20
FCC??? Since when does the FCC have any jurisdiction over HD-DVD
Players???
=20

Unlike DVI, HDMI automatically includes HDCP.

I believe this story has been mis-reported. For HD DVD, DVI with=20
HDCP should work just fine for all output resolutions except 1080p.
