DTS-HD decoding question

[CJS234]

Hey,

I have been wondering something for the past week or so. I am aware that the PS3 is not able to decode the DTS-HD codec yet. I will be setting up my new Onky receiver that is capable of decoding Dolby TrueHD and DTS-HD sometime this week. I was wondering if the DTS-HD audio can be sent from the PS3 under PCM via HDMI to the reciever and then the receiver recognize it as DTS-HD and play it as it is supposed to be played, and not downconverted or anything to PCM.

Thanks,
CJS

The PS3 cannot bitstream any HiDef audio as of yet, possibly down the road in a firmware update.

It sends all Hi-Def audio via PCM, and decodes everything internally, so you can get PCM, Dolby TrueHD, and the Core DTS track so far, but no DTS-MA.

If it is sent as PCM, then that means it has already been decoded. So no, the DTS-HD stream cannot be sent as PCM to your reciever from the PS3. The PS3 cannot bitstream these new audio codecs either. So you better hope that all the movies you watch either have PCM or TrueHD cause you can't get anything but the lossy core from DTS. I bought a new player in order to get DTS-MA and I'm so glad I did!

There's a chance that the PS3 will be upgraded to decode DTS-HD, but there's not a chance that it'll be upgraded to bitstream these new audio codecs.

I agree, and don't care as long as it will do dts-hd ma internally at least.

You might once you are able to hear it decoded. I felt the same way until I got my new player and can now compare the PCM trueHD track to the bitstreamed one. And in every test the one that is sent bitstream is better even though in theory they are the same.

Finally someone that verified what I've been trying to tell everyone here!
Audio is done best when dedicated audio equipment is doing its job.
Sad thing is that profile 1.1 pretty much assures that it needs to be decoded at the player for pip 2nd audio to work.

Why is that? Didn't Samsung just release firmware to allow for bitstreaming of Dolby TrueHD and DTS-MA?

This is not attacking your statement, but just wondering if that is a definate "no" or possibly "no". I only ask since if it seems possible to update via firmware, why wouldn't the PS3 be able to do that?

From what I've read, although it's HDMI 1.3, it's missing the hardware needed in order to bitstream the audio.

That would kind of be a bummer ...I hope it is possible for all of our sakes.

Thanks for the info.

There is conflicting information on this subject and it is quite possible that the newer PS3s have the correct chipset for this to be possible. Though, all might have the capability as of now but it is just not turned on in software.

Here is some older info I came across:

Now it’s worth noting the differences between the two chipsets, “The VastLane SiI 9133, an advanced dual-input HDMI receiver, will enable HDTVs to display Deep Color” whereas the 'SiI 9134’ transmitter is described as having the same capabilities as the 9133 but "with additional support for the latest high-quality audio formats, Dolby TrueHD and DTS-HD Master Audio.”
