Every day now there is at least one or two new posts on it.

The PS3 will convert TrueHD and DTS-HD MA to PCM and stream that, it CAN NOT bitstream DTS-HD MA. Your receiver can not get the signal from the PS3 so it will not say DTS-HD MA and will not need to be able to decode it either, as long as it supports PCM.

That pretty much sums it up. That's exactly what the sticky should say. Well, maybe another line that says, "Next question please".

The chipset in the PS3 is HDMI 1.3 not 1.3a. There will never be bitstreaming capabilities, unless there is a hardware change. You really don't need it anyway.

Thanks for the links
I just wish people would read them more .

The funny thing about this is that I got a $1000 receiver that was being discontinued, so I only paid about $600 (or so) for it. I find it does not support the latest HDMI either, but I don't need it to. My PS3 handles everything else I need!! Awesome.

(I got my receiver last year for $800, and it does not decode TrueHD or DTS-HDMA so yeah, I'm happy that the PS3 decodes these internally).

I'm sure there are very audible differences between internal and external decoding, given gear of appropriate quality (Bose speakers need not apply!). If one accepts that some processors have better decoding than others (e.g., the Onkyo 605 vs Denon's most recent processor), then it also stands to reason that the PS3's decoding ability will also be somewhere on that varying scale.

I guess these are the new topics thats replaced the old one's.......when in ps3 gettting dts-hd..........so now we have to deal with a million threads on whats the difference between dts,pcm,and tru-hd. and the award winner, will the ps3 bitstream dts-hd. oh well what are we gonna do.

I haven't been so happy for a F'n filmware update in my life Something special needs to be said for the Ps3, its got to be one of the 'Top' gadgets of all time , like the iphone, which is way ahead of its time. I feel very privileged to own 3 Ps3's & an iphone. I can't wait to be able too watch my Blu's on my iphone.............incredible......

It's really not a HDMI 1.3 vs. 1.3a issue since with both include bitstreaming support for the advanced audio formats as an optional feature. The PS3's HDMI transmitter chip (i.e., SiL 9132) just doesn't implement this option.

Cheers, Doc.

It's nice to see that you have so much time to "SKIM" each post. I on the other hand don't and would'nt do it even if I did.

I feel that says it all.

As for me, I want a real bitstream of hd audio from my bd player to my avr.

From my personal experience, the LFE channel audio is sometimes (a lot) weaker via HDMI or analog 5.1 when a player (any player) internally decodes any audio track....especially DTS tracks or TrueHD or DTS-HD MA. Mind you... I'm a LFE freak and love to feel the soundtrack in big movie moments. I don't want a whimpy experience, I want a "wow, I think I just wet myself from being so giddy about the sound" experience.

For instance, Transformers blu-ray produces better bass that rumbles my theater when I bitstream the basic DD core track to my receiver via HDMI. It's a shame as the rest of the audio track is truly more awesome when the PS3 internally decodes the TrueHD track. It's just the base that is good but not GREAT when docoded internally (by PS3)!

Another example (and there are many in this category) that bass is really weak ... and noticeably weak ... Try this ... listen to any "big roar or stomping moment" in the DTS version of Jurassic Park DVD. The PCM stream version is good but weak ... the bitstreamed version ROCKS THE HOUSE!! It's night and day difference nearly every time on any variety of mix of dvd players or av receivers.

This been the case with any player I've ever had including HD-DVD and upscale DVD players that internally decode audio tracks versus bitstreaming to my audio-video receiver. The only thing that I've not extensively tested is true bitstreaming of all the hd encodes to a compatible HDMI av receiver. Until recently, no players (with reasonable price tags) were available to joe six pack that could produce your choice of full bistream or internal decoding of all audio codecs from one player.

I've tested hundreds of DVDs and Blu-ray discs to the same effect on various Yamaha, Denon, Onkyo, and Sony (and Sony ES) model receivers. From DVD players from Panasonic, Toshiba, Oppo, Sony, Samsung, etc ...

Bitstream is FOR ME is when ultimate sound purity AND the almighty awesome room shaking bass for blu-ray will come together and blow people's minds. So far, blu-ray audio is good (perhaps even great!) but not freakin' AWESOME!! .... again from the PS3.

NOTE: Included blu-ray PCM audio tracks are the exception to my rant here. PCM audio tracks, and many will agree with me on this, have been so far some of the best sounding audio tracks available on home video. PCM LFE output is awesome and way better than anything I've heard from a TrueHD track (via PS3 decode).

I was sad to see Sony start using TrueHD as their new de facto hd encode moving away from some pretty impressive PCM tracks. I do applaud Fox and Universal for choosing DTS-HD MA .... they rock in my book!

Color me confused but,... my Sub has a volume control knob on the back and I use Digital Video Essentials on Blu Ray to balance it's output with the mains. So.... I really don't understand your comment. If the channels are balanced then the bass reproduction is correct to the limitations of your system and room.

EDIT- Actually thinking this over for a while ... from your description it would seem you would need to balance the channel output for each mode of your AVR ... which certainly is a lot of work. That's actually one of the nice things about having the PS3 output PCM for everything... it makes setting up the AVR a little easier.

Can PS3 Stream out DTS-HD Master Audio to my AVR?

No. But it doesn't need to. PlayStaion 3 decodes DTS-HD Master Audio internally, then sends PCM (upto 7.1 channels) to your AVR via HDMI.

It's not a bad machine, just not the best when to comes to PQ, the main aspect of watching blu-ray.

[DaViD Boulet]

I compared the PS3 head-to-head against the Panny BD50 using Video essentials for my review of the BD50 at dvdfile.

No difference in PQ. None.

Especially funny given that whatever HD DVD player they have probably neither internally decodes DTS-HD MA nor bitstreams it.

BTW, regarding the conversation about audio quality...

I found that the Panny BD50 sounded CLEARLY better than the PS3... but it wasn't a matter of bitstreaming or extracting to PCM! The Panny just sounded better regardless... whether it bitstreamed or extracted to LPCM, it blew my PS3 away with the sonic improvement. So much so that this is the ONLY reason I'm now looking to replace my PS3 with a forthcoming BD55.

Any idea why? Are they just using better parts in the BD50 for audio or something along those lines or could it be some sort of PS3 software issue?

[DaViD Boulet]

No idea why. Jitter? Some sort of processing by the PS3 (along the lines of dialog norm?) that's degrading the sound? Whatever the case, the sound of the Panny was literally like having an entirely new blu-ray collection in regards to audio... and I had heard the same improvement months before with the BD30 so it's not just a fluke. It was almost as singificant an improvement over the PS3 as lossless is over lossy. Now I'm saving my pennies!

[prerich]

Sorry to say - but its easy to best the PS3's audio - that's its weakness. I don't know if it's the DAC's or a number of other possiblities - but my HTPC's 7.1 analog outs sound better than my friends PS3 via HDMI. I believe you David!

So the PQ was equal? the BD50 wasn't sharper or anything? as for the audio, it wasn't a volume thing? what else could it be? the cell processer is no slouch. did you try playing with the ps3's volume control? from lossy to lossless,thats a pretty big statment.

[saprano]

prerich i dont know about weakness, that may be going a little to far. i can hear a big difference from lossy to uncompressed on my ps3,the audio sounds amazing to me.

Whenever you have analog outs, that involves DACs. The PS3 has 2.0 DACs only as evidenced when you use the MultiAV out port. So obviously, there is no DACs for multichannel audio, just decompression for DTS HDMA and TrueHD. The signal stays digital through the HDMI pipeline until it is passed to the receiver.

If what David say is true, then there's two viable explanations:

1) The PS3 decompression for DTS HDMA and TrueHD is incorrect, which causes the PCM to be defective. If this is so, then a firmware correction can be made easily since this is a software decompression. What's intriguing about this explanation is that the PS3's SACD decompression and bit-conversion technique are the best out there, according to Sony's SACD engineers.

2) The PS3 decompression for DTS HDMA and TrueHD is correct, which means that something within the BD50 circuits, either in the DACs, the decompression algorithms, or within the receiver, that is sweetening the audio. If this is so, a similar firmware correction to the PS3 can also be made easily to fix the problem.

Well if it's ether 1 or 2 i dont see sony updating it cause nobody has been compaining about the audio aspects of the ps3.
