Just get some code monkeys working on it, and they'll figure something out. The only way I see this not working is if the PS4 is close enough to release (2 or 3 years) that Sony will just put its efforts into making the PS3 'get by' for now in regards to 3D. I didn't even know you could 'fake' 3D either. A nice, brief thought article their Paul. What are your thoughts on it since you posted it?
I agree they will come out with a workaround - the PS3 is the 800 pound gorilla. Perhaps that was the reason for the one month delay in releasing the PSe 3D Blu-ray update.

Question PS3: May not be able to do 3D and DTS-HD at the same time

Forgive me if this has been discussed already, but per the following website:

http://av.watch.impress.co.jp/docs/n...16_394194.html

(Yes it is in Japanese) it seems like (per what a Google translation is telling me) the PlayStation 3 will not be able to play DTS-HD audio tracks contained on 3D Blu-Rays. To quote the (translated) website:

"However, PS3 for Blu-ray 3D playback is limited to audio output, Dolby TrueHD audio output format, you also will be output as Dolby Digital, DTS-HD are output as the case of DTS."

This could easily be confirmed or denied this Tuesday when the new firmware update is released, but if this turns out to be true that could be bad, because for one thing most if not all (except MvA) 3D Blu-Rays have DTS-HD audio. This could be especially bad because Sony's own 3D Blu-Rays (Cloudy With A Chance of Meatballs and Monster House) have DTS-HD audio on them.

Anyone who might have a bit more knowledge on this subject care to weigh in?

I did the story last week that broke the lack of BD-J. I heard the same thing they did from TGS and have been waiting for confirmation. Unfortunately I did not and do not have confirmation on it like i had with BD-J, so I didn't run that part of it. However, AV Watch is fairly reputable, so if they're hearing the same things I am, I'd file it under "probably true" until proven otherwise on Tuesday.

BD-J was dropped due to the second 1080p stream eating too many cores. I'm guessing it's eating even more than originally thought.

Is that just for PCM output which I would guess (correct me please if I'm wrong) would required more processing power than bitstream, hence only the pre-slim models would be affected?

Why would it be more difficult to decode DTS-HD that Dolby TrueHD?

I am not sure why, but has it not been mentioned several times over the years that dts-ma is more processor intensive than TrueHD?

We will know tomorrow. I really can't see the PS3 not supporting all the sound formats. Perhaps that was why they did the slight delay in releasing the 3D firmware - to work out how to do it.

I would assume that bitstream would not be affected, since there's no way that even has the CPU overhead of decoding Dolby Digital

It does, that's why a lot of early players could only do DTS-HD and not the Master audio. As I understand it, the additional processing power required for muxing the core DTS and the HD parts and keeping them in sync. TrueHD is a straight decode.

Both lossless formats are affected, not just DTS

I just did a search on DTS-HD and DTS-HD Master Audio - I think they are the same - did you mean DTS vs DTS-HD Master Audio? What do you mean by both losless formats? - Dolby and DTS?

No they are not the same.

Yes. According to Wiki, "DTS-HD High Resolution Audio is supposed to be an alternative for DTS-HD Master Audio where disc space may not allow it".

It appears to be official - both lossless audio formats are NOT supported for 3D movies.

Well this is a serious limitation. The lack of BD-j was inconsequencial given that the best picture isn't really required for extras but lacking lossless audio is a serious limitation. The best video should not come at the expense of audio. Audio is half the experiance.

The biggest difference is that HR is lossy, MA is not.

Guess it really doesn't effect phats as they can't bitstream HD audio.

I guess we shouldn't be too surprised about this. Its remarkable the Playstation 3 can do 1080p 3D at all given its HDMI 1.3 product from 2006.

Can anyone answer the question if it can't pass lossless audio and 1080p 3D at the same time can it at least pass 1080i or 720p 3D and lossless audio at the same time? Cause I think a lower resolution 3D might be preferable to dumping lossless audio.

Either way this is the best reason ever to own a stand-alone 3D Blu-Ray player.

My Ps3 slim is updating as we speak. I'll try a few of my titles to see what happens.

I think phats are exactly the ones that are affected.

See I'm not surprised at all because we always heard right from the getgo that the PS3 had the power to decode 2 @ 40 Mbps AVC/MPEG-4 streams at the same time and MVC/MPEG-4 is only 50% headroom over a single stream.
