I wasn't sure where to ask this.I am looking at getting a Bluray player. i have been doing reviews. I am interested in the Ps3 because of value and upgradability (you also get SACD). I was wondering about the Dolby TruHD. Here is a article i read in a review and I don't quite unsderstand it.:
HD movies look superb on the PS3, which can output video at full 1080p resolution via its HDMI 1.3 port. Audio support is also top notch: the PS3 decodes Dolby TrueHD and DTS-HD Master Audio soundtracks internally, outputting them as linear PCM, which should deliver impeccable lossless surround when connected to most HDMI-equipped AV receivers. Sticklers may lament the lack of "bit stream" audio output or multichannel analog connectors--if either is an issue for you, than you're in the small minority who should opt for one of those more expensive standalone Blu-ray player.
I am using a Denon 3808. Will i get degraded quality. Wasn't sure what linear PCM meant. Thank
Follow Ups:
The following pertains to the lossless codecs and transmission via HDMI:
Where the lossless codecs are concerned, they have to be decoded to PCM somewhere. The decoding can happen in the player or in the receiver/processor. If the player does the decoding, multiple channels of PCM are output to the receiver/processor via HDMI. If the player is capable of sending the compressed track over HDMI (not all players can do this), then it's up to the receiver/processor to do the decoding of the compressed track to PCM. Not all receivers/processors can decode the new lossless codecs. There are also players which can do both (but not at the same time), decode internally and bitstream (send the track over HDMI without decoding it first).
The PS3 will decode the Dolby TrueHD soundtrack from its losslessly compressed state (similar to a zip file for computers) into multiple channels of PCM (similar to what's on a CD, except more channels). The multiple channels of PCM can then be transmitted over the HDMI cable to your Denon receiver. The receiver will show something like Multi-Channel PCM on the display. It won't show Dolby TrueHD because the PS3 has decoded the compressed data, which is the Dolby TrueHD soundtrack, into PCM.
As for SACD, the 20, 60 and current 80GB models play SACD. The 40GB model doesn't play SACDs (except for the CD layer). I believe there's a new model 80GB to be released (or it may already be out) that doesn't play SACDs. Make sure that if you want SACD playback, the model that you get will actually read the SACD layer of SACDs.
thanks everyone. Joe, yes the new 80 gig models are out now without the sacd at the stores. I have been looking for an older one. My son has an 80 gig model that I got him for Xmas that has sacd and backwards compatability with PS2 games. I told him i would buy him a new one if he gives me that one so I can have the sacd functionality. He lives with my ex so his ps3 isn't over at my place all the time.He doesnt play ps2 games anymore so he agreed. He's 13 yrs old and thought I was trying to con hm at first. Hehehe.
Chrisc I don't know what all that means either, I can tell you I just bought a ps3 and use toslink to my reciever and component to a pioneer elite and it is awesome. It beats directv high def on my RP elite.
To take advantage of the Blu-ray audio formats you need an HDMI cable to carry the PCM output by the PS3, as stated in the initial post.
-------------Call it, friendo.
Your right Toslink will not transfer optimum high rez multichannel audio but older rear projectors like my elite do not accept HDMI, however, IMO it is unbeatable for picture resolution...
