Denon question

[Twotree]

I have a Denon AVR 2808 Receiver and a Sharp Blu-Ray player that
decodes DTS HD ,True HD and most of the other good sounds. My
question is: On the Denon display when the source is DTS the
display should read DTS-HD or DTS-HD Master, when a Dolby Digital
source of True-HD the display should read... DOLBY True HD. The
display reads only Dolby digital and I have it on standard. Some
movies will read just Dolby DTS when the correct source is there. Is
there a setting that I am missing or is there a way to get the Denon
to display correctly? I have a demo disc from the CES show in Las
Vegas with all the sounds and it will display DTS-ES Matrix 6.1 or
just DTS Surround. I hope that this is not too confusing. The movie
menus display the inputs and my Blu-Ray player decodes them but the Denon will
not display the correct readings and I would like to know if I am
getting the true sounds. Denon tech support told me this:

Since the player does the decoding then the only way to connect it to
the 2808 is to use the multi analog outputs on the back of the player
to the Ext. In on the 2808. The receiver will then need to be put in
the Ext. In mode and the display of the receiver will read Multi Ch
In. You will get the new HD audio formats but it is put out in LPCM format.

My response:

If what you say is true that your way is the only way to hook it up
then why do I get the output to read DTS and DTS-Ex Matrix 6.1?

Denon response:

Because you are getting the core data, not the HD audio formats.

I was under the assumption that you needed an HDMI cable for DTS-HD
ect. to get the sound to decode right.

Can anyone clarify this situation for me as I am not an audiophile?

THANK YOU

It depends on whether your BD player can bitstream the HD audio formats. If it can, then you only have to set it to HDMI bitstream and the Denon will do the rest.

If it cannot bitstream it then it most likely can send the decoded (LPCM) HD sound via HDMI and may be even the analog outs. In that case the Denon will just display multichannel (ext in for analogs) in. What is the model number of the Sharp?

The display function of a receiver will show the format of the incoming data. When you send DD/DTS/DD-EX/DTS-EX/etc to the receiver as a bitstream the receiver recognizes the format and does the decoding itself. Since it knows the format of the data it can display on the screen.

When the player does the decoding, it sends PCM and in the case of the new HD formats, multi-channel PCM. The receiver doesn't know what the original format of the data was and so would just show MPCM. You'd have to be using HDMI to get the multi-channel PCM. If you had the player configured to output PCM (and using optical or coax digital outputs) the receiver wouldn't show DD either, it will show 2 channel PCM.

If you are using the analog outputs of the player, not only is it decoding it to multi-channel PCM but also converting each channel to analog. Now your receiver really has no idea what the original format was and should show nothing but 'ext in'.

Denon's response was correct.

Thanks for the replies!
I have a Sharp Blu-Ray player model BD-HP20 and it is connected using HDMI. There are no multi channel outs on the player.

I did a search and could not find the HP20. I did find the HP20U. The 20U has multi channel analog outs, digital out, and HDMI out but its HDMI cannot bitstream.

O.K. Here is another stupid question? If the 5.1 outs of the Sharp (which are ctr ,sub ,fr l+r,rear l+r) connect to the multi channel
in of the Denon which has Surround back speaker connections how will I get 7.1 with no input? Also when using "ext-in" the Denon will display "ext-in". Then why does the reciever have all the different displays according to the input signals if all you can see is ext-in? Thanks again

You will only get Discrete 5.1 if you use the 5.1 Analog Output of the Sharp BD. You will not get discrete 7.1.

The only way to get discrete 7.1 is if your player has a 7.1 Analog Output or if you use HDMI.

Otherwise, you would have to use ProLogic IIx to MATRIX the 5.1 into 7.1.

When you use the Ext. In. (Analog Inputs) the receiver is not DECODING anything. It is just taking the Analog signal from the player and sending it straight to the amplifier section.

The different "displays" on the receiver for DTS Master, etc, are only there if the receiver itself does the decoding. Since it seems your player WILL NOT bitstream the audio, the player itself does the decoding and the receiver does not "know" what audio stream it was sent-it just see's it as LPCM (multi-channel). Therefore, it will not "lightup" the different DTS Master, DD+, etc displays on the receiver. You are still GETTING HD audio-don't worry. The only thing that is different is that your Bluray player is doing the decoding and not the receiver.

You may need to go into the settings of the player and set it to output LPCM (or a similarly named setting) b/c your receiver should NOT be saying Dolby Digital or DTS with the proper signal. As Denon said-you are receiving the lower bitrate core audio track if it is saying this.

Let us know if you have more questions.
