At some point, you just have to know when to give up and enjoy your movies (in DTS-HD MA and LPCM

).

These guys (there's one in every village

can enjoy it on their shiny HD DUD movies

As for DD+ on Blu-Ray:

And even if you found it... it would still suck because it ai'nt LOSSLESS

Why is always important. To do otherwise is to dispose of rationality and delve into emotions.

Did you miss the shuttle to Vulcan or something?

P.S. Live long and prosper

OFF TOPIC --> to liven up this stale conversation... watch this hilarious youtube video from "The Office":

Which 3 and where? (besides Penton-man)

I sort of agree with this - but in a specific scenario.

First, a uncompressed DTS-MA file and a PCM file will be identical.

Now where I think the difference may happen, is that if your receiver or pre-pro is doing the uncompressing, it is using CPU cycles to do this. This takes away from the receiver's CPU power to perform post-processing (i.e. matrix 5.1 to 7.1, etc) since PCM would not have to deal with that...PCM would free up resources on the receiver to deal with post-processing (i.e. better matrixing).

Of course, if your player deals with the uncompressing, the above does not apply....

How much louder will it get when DTS HD MA gets implemented??

So, maybe this has been anwsered somewhere else but:
- What is better? Have the PS3 decode the soundtrack internally or have the PS3 pass the bitstream and have the receiver decode the soundtrack?
My early guess is depends on the quality of the DAC's found in the receiver?

I know one other, that's the sony insider, paidgeek.

One final note: why doesnt the PS3 just sends the bitstream of both DD HD MA and DTS HD MA?

(sorry if i asked a dumb question...)

Not dumb... just one that could have been answered with a tiny bit or research and/or the use of the "search" function.

The answer is: The current PS3 hardware is not capable of bitstreaming either Dolby TrueHD or DTS-HD MA and no amount of firmware will EVER make it able to do so.

Maybe a future edition of the PS3 will come with a revised/different HDMI chipset... but the current PS3's are incapable of it.

My preference - have the PS3 decode it locally and send it as pcm to the receiver or pre/pro for the reason right above your post....

Well, it depends on the quality of the chips, doesnt it? A high end receiver (Denon, Yamaha) would do a "better" job converting the bitstream wouldnt it?

I guess the big one is: why on hell didnt Sony enable a bitstream only option capable of passing DTS and DD HD formats?

Damn!

PNF · 03-19-2008, 12:54 AM

Is this a software or hardware change? (if so, adaptor??)

software update? or I have to buy a new PS3 that contains the truHD, HD MA?

Simplayer · 03-19-2008, 12:59 AM

It's a future software change (firmware update).

If the codec is lossless, I think it is no difference to be decoded by receiver or PS3. and the ps3 maybe preferable since
1. the cell processor of ps3 is power enough
2. you can save bunch of money w/o having to buy latest receivers that can decode dolby trueHD and DTS-HD MA.

Thx. I did SOME research about it when I was trying to find out if the PS3 was capable of outputting DTS HD MA. I did find out that the current HDMI chipset was not capable of doing it, even with a firmware update... guess I was wrong, according to this topic.

Peace!

I have another problem.

Since I heard PS3 is already support Dolby TrueHD. However, for my experience, for those titles which support both PCM and Dolby TrueHD, there would be a lot of difference to my ears between these 2 sound track. PCM seems much better than Dolby TrueHD. My PS3 was set to HDMI output for linear PCM. In theory, if ps3 support dolby truehd, there should no difference between PCM and trueHD, any settings I overlooked?

Simplayer · 03-19-2008, 02:13 AM

PCM is probably getting output about 4dB louder than Dolby TrueHD. Since loudness is generally perceived as clarity, that's probably it.
