Shy HD and DD 5.1 over HDMI
 

I'm an idiot!

I should have checked before I bought a sony av amp to do the HDMI
switching. I have 3 HDMI inputs, SAT, DVD and BD only to discover that the
Sky HD box does not output DD 5.1 via HDMI. DD 5.1 is only output via
optical which doesn't match any of the video inputs!! So I can have Sky HD
with PCM 48 sound and picture or Sky HD with DD 5.1 (Video2) and no picture.
Unfortunately my TV only has one HDMI input.

It may save somebody else buying a modern amp which no longer matches the
now 'out of date' Sky HD box. As the current Sky HD box has been around for
a some time and HDMI standards have evolved, can I make an appeal that the
next release has DD 5.1 via HDMI.

HDMI has been designed NOT to allow you to decode 96kHz 24bit audio via an
AV amp or similar equipment if the content is copyrighted even on an HDCP
enabled amp. The ONLY way you are allowed to listen to it is via an ANALOGUE
5.1 output on your STB, DVD player, or Blu-Ray player, assuming you have a
spare 5.1/7.1 input on your AV amp, and don't expect to be able to use your
7.1 speaker system unless your box or player has 7.1 up-scaling built in. If
you do not have a 5.1/7.1 analogue input the only option open to you is a
downsampled 48kHz 16bit version.

HDMI was not designed to disallow anything. And HDCP was certainly
intended to convey the full audio from one HDCP enabled device to
another. I'd guess that you actually do have something in mind about
some problem with the implementation of this, so is there any chance that
you can switch yourself out of ranting ******** mode and actually state
what that is?

No it wasn't. It was designed to stop it outright. Read your player's
instruction manual.

I already posted about this over a year ago. Copyrighted audio over HDMI
(even with an HDCP enabled amp) is limited to 16bits at 48kHz.

How many channels? (this is CD quality by the way).

How does one lash up an AV amp and a screen to say a Blu Ray player? HDMI
to the screen and optical / coax to the amp, or will you have to take analog
from the player to the amp?

Nonsense. The HDMI and HDCP pages on Wikipedia say that HDMI can handle
multi channel audio and that HDCP is intended to limit audio on *non*
HDCP outputs. My instruction manual? So we *are* talking implementation
issues, then. So what are they?

I setup a PS3 to a Yamaha 7.1 AV amp the other day. output to SIM2 D80e
projector, KEF 5005.2 speaker package with 2 extra speakers for 7.1. The
PS3 connected only with HDMI to the amp detected 7.1 surround sound and
played audio in fun 5.1 and 7.1 as required on the bluray.

5.1 if the recording is in 5.1.

Nope. It limits HD audio on ALL outputs and inputs including those with
HDCP. If you want HD audio and it is copyrighted you are stuck with
analogue, ie. decoding by the player.

The HDCP spec is the issue. 96kHz 24bit audio transmission is forbidden for
all domestic interfaces.

Right. So was it 24bit 96kHz? I doubt it, if the copyright flag was set. It
was most probably down-sampled by the player before being passed to the amp.
