will the PS3 bitstream DTS MA

[blueraybum]

Or will it send it out as pcm just like it does with TrueHd.

[BStecke]

PCM only.

For now it might just be PCM, however; with the firmware updates, who knows how far the PS3 will go.

The PS3 will never bitstream TrueHD or DTS-HD. It does not have the correct hardware to do so.

[Petra_Kalbrain]

All HD audio coming out of the PS3 will ALWAYS be decoded by the PS3 itself and sent to the receiver as a PCM signal!!! This is never going to change.

PS3 CANNOT AND WILL NOT EVER BITSTREAM HD AUDIO, period.

optional upgraded chipset's for pre order yet? ............

Although I wish it had bitstream, I do laugh that this is the final little piece of desperation that HD-DVD owners are clinging to in the hopes of calling the PS3 a bad machine.

That's what they said about DTS-HD MA internal decoding too, but now, just wait for April 15th.

The PS3 uses the Silicon Image SiI9032, which transmits HDMI 1.3 protocols. It supports deep color and advanced audio transmission.

Whether the SiI9032 supports bitstream transmission of Dolby TrueHD and dts-HD Master Audio or not is still a debate. It has not proven to support bitstreaming, but it has not been proven otherwise either.

Just hang on, there could be another surprise.

Why does it give bitstream options in under BD/DVD settings? Or is that for dvds only?

That's for old audio encoding, Dolby Digital & DTS Surround only.

For those wondering about bitstreaming, just do this test.

Set your BD audio output to bitstream, and then watch a BD with the legacy Dolby Digital (NOT TrueHD) track.

Then change the audio output back to PCM, and play the same movie again with the same audio track. How does it compare?

Well, I've done it myself, the result is, I don't need to bitstream, decoding the audio internally by PS3 is just the same, if not better. But that's to my ears. How about you guys?

[zdefonte]

Is there really an audible difference whether the codec is decoded internally by the player or decoded by the receiver?!? I don't think there is...so I do not see why it is important for bistreaming, other than justifying your purchase of a more expensive A/V receiver.... (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).

It looks like the hardware has the power. Amazing design. PS3 RULZ!!!!!!!!!!!!!!!!

I'm wondering this too.

There never really was a serious question whether the PS3 could do DTS HD-MA decoding and output via LPCM since this was strictly a software (firmware) upgrade. This only real issue is the PS3 using a SiL 9132 HDMI transmitter chip that according to the only information available from the chip manufacturer does not support the advanced audio. Their SiL 9134 that is used in standalone BD players does add this capability. Below is a copy of info I posted over on the AVS Forum a few months ago.

According to the brief feedback provided from the chip's manufacturer provided in this thread, the SiL9132 cannot support bitsteaming for the advanced audio formats. As for the old news release from SIL the final sentence of the following paragraph could be read that the SiL 9134 has the additional capability, beyond that supported by the PS3, to output the advanced audio formats via bitstream:

“Sony has indicated that the PlayStation 3 is expected to ship in November of this year with the ability to render the highest-quality video ever seen in a consumer device,” said Dale Zimmerman, vice president of marketing at Silicon Image. “The SiI 9133 receiver matches the capabilities of the PlayStation 3 and makes it possible for HDTV manufacturers to ship products this year that are capable of displaying Deep Color images, for the highest-quality gaming experience and fullest enjoyment of high-definition movies. The SiI 9134 brings these same benefits to next generation DVD players, with additional support for the latest high-quality audio formats, Dolby TrueHD and DTS-HD Master Audio.”

As for sound quality when using bitstream out of the BD player and the AVR doing the decoding versus decoding in the BD player (e.g. PS3) and outputting to the AVR using LPCM, here is my 2 cents worth. It is technically possible to deliver equal performance but some AVRs and preamp/processors don't. Passing LPCM via HDMI is known to introduce additional jitter (timing errors between bits) and many AVRs will pass these data timing errors onto their Digital-to-Analog converters and this can degrade sound quality. However, it is relatively easy to include a data buffer and reclocking of the LPCM data steam within the AVR and if this is done then the level of jitter need be no more than for the case where an encoded bitstream is being passed from the source device and the AVR in this case is forced to provide the clocking for the decoded bit string that it sends to the D-to-A converters. Thus there is no absolute answer possible as to which is better since it depends on the specific hardware implementation in the AVR or preamp/processor. My own background is 30+ years as an electronics engineer dealing with digital communications systems and digital signal processing.

MIGHT nuthin'... Because of the HDMI chips that are used in the PS3 - Bitstreaming of lossless info (True HD and DTS-HD MA sound files) is

Impossible

Search function is your friend... please use it if you can

Cheers, Doc.

No matter how it does it or if it is possible, the PS3 is still a mindblowing system. I'm amazed at all of the recent updates, and now the one on the
15th. Whether it decodes to LPCM or bitstream or if it can't the PS3 still makes my BD movies look and sound amazing, and that's what matters most.

Thanks for your input Ron. That's as clear and concise as I've ever heard it. Nice to have an electronics engineer on board who can contribute that kind of additional info.

If we don't already have one, I think we need a sticky that goes over DTS-HD MA and TrueHD on the PS3.
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.
