amirm confirms DTS output for the Xbox 360 HD DVD

"Just a quick FYI that we are looking at this problem. I don't have an update on it because I was on vacation for a while. But for now, wanted to let you know that we are finalizing our DTS encoder which once done, should produce the same experience as the Toshiba player which everyone was happy with...."

Time to return my HD-A1...

EDIT

Since so many people seem confused:

HD DVD DTS --> Decoded on Xbox 360 --> Player sounds mixed in --> Re-encoded to Dolby Digital 5.1 --> Output via SPDIF optical
HD DVD TrueHD --> Decoded on Xbox 360 --> Player sounds mixed in --> Re-encoded to Dolby Digital 5.1 --> Output via SPDIF optical
HD DVD Dolby Digital Plus --> Decoded on Xbox 360 --> Player sounds mixed in --> Re-encoded to Dolby Digital 5.1 --> Output via SPDIF optical

Thus, your receiver always receives Dolby Digital 5.1 (640 Kbps), regardless of what the original track was. However, some people have noted that on some tracks on some discs, the sound was a little bit flat.

Microsoft will be releasing an update that will allow:

HD DVD DTS --> Decoded on Xbox 360 --> Player sounds mixed in --> Re-encoded to DTS --> Output via SPDIF optical
HD DVD TrueHD --> Decoded on Xbox 360 --> Player sounds mixed in --> Re-encoded to DTS --> Output via SPDIF optical
HD DVD Dolby Digital Plus --> Decoded on Xbox 360 --> Player sounds mixed in --> Re-encoded to DTS --> Output via SPDIF optical

This new DTS output (1.5 Mbps) should hopefully correct the "flatness" some people have noticed with the previous Dolby Digital 5.1 output on the Xbox 360.

Timeline for the update? Weeks, months? Download or CD-ROM?

this is enough for me to maybe buy a 360 addon instead of a new denon DVD player, but we will see.

Yee haa!! nice to see improvements already on the way for the add-on. Wondering what "finalizing" means though... weeks or months?

I'm excited too... but what does it mean exactly? Haha.

Is everything going to be downconverted and sent through DTS at 1.5mbps now instead of DD5.1?

Precisely.

Hopefully this will correct the dynamic compression issues that have voices as loud as explosions and gunshots.

Ugh, I don't like this at all. I am not a big fan of DTS as the dialogue is always low, so I have to turn it up. But when there is some action, the audio is too loud. I wouldn't mind this, but I live above my landlord so I can't have it too loud.

Boo. I just won't update it or something.

I imagine there will be a new dashboard option to select DD or DTS output.

It would have to be. They can't replace dd with dts, since not every receiver out there supports dts.

I am curious, though, if this is basically an admission of sorts that dd output can't really get any better, so the fix is to add dts output.

Either way today I went into my dashboard, where the music controls are, selected the speaker icon and cranked it to 100% (it's set at about 30% by default) and then played King Kong. Noticed a big difference. I am wondering if this was the main problem all along.

Well... it didn't stop Toshiba from re-encoding to dts only over optical/coax.

I am confused. I just watched Riddick and selected DTS and DTS scrolled on my receiver. This already is able to pass DTS. What are you guys talking about?

Does this not also mean nearly tripling the bit rate from 640kbps to 1.5Mbps? Or is it going to be some sort of half-rate DTS implementation?

The statement that Amirm made didnt say that any DD or DD+, TrueHD would be re-encoded to DTS, it only states they are producing a DTS encoder. He did say that they were looking at the poor quality sound problem on the DD sountracks, it does not necessarily mean it will be fixed with the DTS update.....although I'm hoping it does!

Am I reading his statement wrong ?

HD DVD supports the new audio formats, which includes Dolby Digital Plus, Dolby TrueHD, and DTS-HD Master Audio. No receiver out today can decode these new formats, so in order to hear these formats the player or receiver will need to be able to decode them. The 360 can decode Dolby Digital Plus and Dolby TrueHD, but since it has no hdmi or 5.1 analog audio outputs, it must re-encode those new formats to Dolby Digital so that it can be sent via digital optical (or coax). So here, we're talking about the potential 360 functionality to re-encode to DTS for these new audio formats.

The Riddick HD DVD has a dolby digital plus soundtrack in addition to regular DTS.

But in my own way, I am King. Hail to the King, baby.

HD DVD. DVD version only has DD 5.1. I will say that DD 5.1 playback on Riddick on my 360 is less dynamic then the SD DD 5.1. DTS was much better but I have no way to compare DTS since the sd version has none.

I know this already but the subject of this thread was DTS coming to the 360 and since the 360 can pass it to any receiver, it seems confusing to me. If they are talking about the advanced audio options, it would seem that any change would have to be a hardware change since the XBOX doesn't have HDMI or 6 channel
audio outputs. Am I making sense. I hope so.

Could it be a firmware upgrade we are talking about MS doing and not a software upgrade to the add on or Xbox?
