HD DVD's Managed Copy with Xbox 360 Extender
Button member Neon asked a
question about HD
DVD's Managed Copy with Xbox 360 and I thought I would post a bit of the
information here too, since many people have the question on their minds.
The question was asked by Neon, “With Vista there will
be the ability to make a Managed Copy of HD DVD, but the question remains what
format will it copy too, and will it be able to be played on an Extender or 360?”
There will be much more information on this in the upcoming
months. However, AACS is going to define a "Managed
Copy" as making available the same resolution and functions (user
experiences, menu features, etc) as the licensed physical content. This would lead
most to think that it will be an exact copy in its original form.
Now, AACS is also going to include WMRM (aka WMDRM, I like
to leave out the "D" since "DRM" makes people uneasy) which
is Windows Media Digital Rights Management as an "Authorized Digital
Output". Your Xbox 360 supports WMRM and even better it support WMRM-ND. That -ND stands for Network Devices which is
approved for "Remote Viewing" which everyone basically calls streaming.
I'm not sure what the plan is for streaming the content
around (in terms of the format), but if on-the-fly converting to WMV9 could be
done I would think that would be choice for bandwidth considerations. I don’t know if WMRM can be applied if the
content isn’t ASF/WMV, it will be interesting to see and again it’s still going
to be a bit before all details are released.
The Xbox 360 is going to have to get a software update (unless
it’s already in place: InterVideo?!) when Microsoft releases the External
HD DVD Drive since it will need to be able to decode MPEG-4 AVC, in
addition to MPEG-2 and VC-1.
The way I'm reading things you still need HDCP output to get
full resolution playback, so Microsoft is going to have to release
a new dongle which will most likely have HDMI in order for the Xbox 360 to
output full resolution. Unprotected output with WMRM is not allowed from what I
Note: I have seen Blu-ray presentations that say BD+
doesn’t interfere with Managed Copy.
So, if true the above relating to Managed Copy would also apply to Blu-ray once released (one would think).
