Hardware Requirements for HDDVD/BD

[TT-]

I recently bought a PS3 (yet to hook-up), and I have a question for those who've been in the HD games. Would I required to buy new receiver/processor in order for me to decode the True HD Dolby or the lossless DTS?

For TrueHD and DD+:
If your receiver has HDMI or 5.1 analog, you can decode these formats.


For DTS-HD:
I think the BD players are doing the decoding for this, since there are no DTS-HD receivers yet. However, I'm not sure that the PS3 can do this. Someone correct me if I'm wrong.

EDIT: The PS3 does not internally decode DTS-HD. However, it may be able to with a future firmware upgrade.

An answer should be forthcoming...ya gotta be a little patient though.

Well, I guess I have to buy a new receiver/processor in the near future for these new audio format. My receiver neither have HDMI nor 5.1 analog, but it does just about everything else. DTS ES, DD EX.. etc.

I'm planning to add a new amp anyway, maybe sometime down the road.. when the format war is "over," then I'll plunge down some cash to get the appropriate processor. Right now, I'm content with DVD and I don't see any reason yet to get either HD-DVD or Blu-Ray just because I can't afford both.

Thanks for the reply!

Keep in mind that your receiver will downmix the new audio formats via coax or optical, so it'll still sound good and you'll still have the awesome picture quality.

Good luck!

How can it if it can't decode the new formats? If his PS3 is connected via coax or toslink, won't the PS3 output DD or dts audio and not the new audio formats?

Peace...

I can't say for sure because I don't own a PS3, but if it operates like the A1, it will downmix the DD+ to DTS.

That sounds like the player will do the downmix, which makes sense. Your previous post implied the receiver would do the downmix vs the player doing it.

I could be totally backwards on this. It’s been a while since I messed with using coax or optical, but I believe it is the receiver that does the downmixing, at least with the A1. My original "it" implied the receiver.

The PS3 may be totally different.

I think you are confused. The receivers out today don't understand the new audio formats, obviously, so the player has to do any decoding or conversion. I believe the HD-A1 would convert Dolby TrueHD to dts before outputting via coax/toslink and I have no idea what the PS3 can do.

If the player outputs digital audio, it has to produce the digital output. At this point, only the players understand the new formats so how could the A/V receiver do any downmixing or conversion from the new audio format to DD or dts?

I think you mean the player will downmix Dolby TrueHD to DD or dts and output that via coax/toslink to his current receiver and that will still sound good anyway.

Peace...

That's very possible.

If SPDIF Audio Output is set to Bitstream (the default) you will get the new formats either transcoded or re-encoded to standard DD or DTS. The format depends on the disc, but the launch titles all use "Advanced Content" which is re-encoded to DTS at 1.5 Mbps by the XA1 and A1.

If SPDIF Audio Output is set to Bitstream (the default) standard DD or DTS streams on DVDs will be passed as that bitstream.
You can only get 2 channel PCM over SPDIF. If you set SPDIF Audio Output to PCM, you will only get 2 channels.

Which receiver do you have that has the common digital audio decoders but no 5.1 analog inputs?

I have a Sony ES receiver, I think it "might" do the 5.1 analog input (i haven't look in the back and haven't check the manual). I bought it 3 years ago so it's been a while since i got it setup. I doubt the PS3 will have a decoder that let me output 5.1 analog to the receiver.

The PS3 has a built in Dolby TrueHD decoder, but not DTS-HD. I was wondering about how I will be able to decode them — would seperate/external decoders be available, or would I have to look into another receiver? (or, you know... live with what i have!!?)
