New HD decoding-Do they Exist?

[Harrison476]

First, as a new member I would like to “score one” to the Audioholics site and members!!! For excellent discussions and reviews!
Recently like a whole bunch of US consumers I decided to Jump into the HDTVworld, so I started by researching HDTV ( a month later) confused but Hooked I decided on a HDTV. Next, I needed more power (lol) to my receiver. So I started researching new receivers. I can not believe it but I finally threw down an got one of those! Next, I have to add to my existing speakers, so i'm 7.1 now, up from 5.1.

Well, I am impressed with all the new things and set ups I have. I made one big mistake it seems. During the purchase of my new TV (all excited an all) I bought a BD player without researching! Now to my real question and reason for the post:

Dolby Digital plus, Decoding, Dolby TrueHD, dts-decoding, dts-HD (there is a #1 and #2?)And please excuse my language, Damn, A MASTER???

Could someone put all this decoding stuff in perspective? I am beginning to wonder after trying to talk to one of the major manufacture in the world several times an I have yet gotten the technical support people to address questions regarding Audio capabilities of their own product, if there is such a thing as TrueHD sound?

I'm not sure I follow the question - are you asking do Dolby True HD and DTS-HD exist? If so, the answer is YES. Can you play them back? It depends...what receiver did you get and does it have HDMI? Dolby TrueHD and DD+ can be decoded by some receivers. Right now, I am not sure there are many or any that can do DTS-HD MA right now, but both will be able to soon enough. TrueHD and DTS-HD are backwards compatible as well - you can play them back via standard digital, though you get only 5.1 and possibly a lower bitrate than the original this way. It still sounds very good though. Another option is, if the player can do the decoding, you can use the multichannel analog outs from the player to the receiver. Note that these formats exist only on Blu-ray and HD-DVD discs.

Thanks! I really didnt want to state the products I bought, but since your feedback is striking some of my mental recall I will take advange and see if you can help this old guy.
equipment:
blue ray- sony s-300
receiver-onkyo 875
tv-sony Xbr

The problem I am having besides the fact that I am just learning most of the terms is:
While playing a blue Ray disc, I can not seem to get an indication from the receiver that a HD format is playing. Example: I have seen dolby digital and dolby EX , but never True HD? Or any of the newer formats.

All my connections are through HMDI
thanks again for your response

Your receiver probably shows the signal PCM or some variation of that. This is because unlike what most people have their dvd players set to, bitstream, most HD players only decode the HD audio formats internally and send out an already uncompressed, decoded, signal hence the PCM signal rather than HD.

Since your receiver can internally decode HD audio formats if your Blu-ray player has had a firmware update to send a bitstream signal to the receiver then it would show TrueHD or DTS-MA on the faceplate.

To ensure you have the HD audio setting if you can't use bitstream just click the language/audio option on the BD before you start up and then choose the HD format so you know it is running.

FYI: Bitstream is an unaltered, decoded, version of the audio while PCM is an already decoded version. Either way you will get the same sound quality unless your receiver does a better job decoding than the BD player which I would doubt.
