Dts Hd

[Mulder]

I know this has probably been asked before so I'm sorry. From the threads I've searched, it seems that the only signals one can receive throughb an optical or coaxial cable is DD 5.1 and DTS. Can someone confirm this for me? Are these really the only two signals? I have a FOX BD which uses DTS HD and the sound is not really working with my current setup. Any info please!

i need the answer too

If you have optical/toslink, you will only receive the core DTS audio. While it has a higher bitrate than you would get from your regular DVD, it is not the HD version. Still sounds good, but could be much better.

Not sure as to which source products decode the DTS HD audio. I know that the PS3 currently does not.

It's an issue of bandwith. The older optical/coax pipeline can't handle the higher resolutions, so you're stuck with a max of DD at up to 640k/s or DTS at up to 1.5m/s.

DTS HD and DTS HDMA have a "core" that can be extracted and sent via coax/optical at 1.5m/s and sounds really good, but is not the full HD or lossless HD Master Audio.

Exception: if you only want to get 2 channels, and your BD or HD-DVD player can decode it, you can have DTS HD or Master Audio send via coax/optical at full resolution (since it's just 2 channels).

Right now there are no players that can decode DTS-HD or Master Audio that I am aware of. Many new receivers can now decode it, but to do that they need to have the original signal sent as a bitstream from the player, and very few players can do that right now (the PS3 can not, for instance).

So if I play DTS HD through an optical I'll end up getting normal 5 channel DTS? Do I have that right?

This is an excerpt...

The audio carried by HDMI seems a bit confusing right now because ear-candy like DTS-HD Master Audio, and Dolby True HD can only be run through HDMI, not Toslink or Co-ax but the fine gent I talked to at DTS via phone and e-mail, added that their backwards compatible core can be decoded at 1.509Mbps by your legacy receiver. That’s pretty much the highest your current receiver can do depending on the manufacturer. That, is still greater than what you’ve been pushing with standard DVD which was encoded pretty much with 758kbps—usually to save space. This is why, when you hear ‘regular’ DTS (or possibly DD as well but this is not confirmed), on your current system from Blu-Ray or HD-DVD, the voices are more distinct, the LFE is tighter… not as muddied and your steering tends to be a bit more precise. I’ve definitely confirmed that on my setup at home.

According to the DTS website, Blu-Ray’s HD audio capacity has a higher ceiling for the new ‘Hi-Definition’ audio than HD-DVD. How much higher? Well, with Blu’, the site states 24.5Mbps per HD Master Audio compared to 18.0 on HD-DVD. The DTS High Resolution Audio is 6.0Mbps on Blu and just 3.0 on HD-DVD. That’s not a choice, it’s simply the space restriction on the latter format. The other important thing to note about the new HD audio formats, is that you DON’T necessarily need HDMI 1.3 to carry them. My contact at HDMI says all previous versions of HDMI will carry the new HD audio paths. DTS on the other hand says that’s not entirely true. DTS says more specifically, that if the PCM output is used, the DTS-HD can be run through analog outputs but add, earlier versions of HDMI were tested in their labs and as a result, any previous version of HDMI other than 1.3, will NOT carry DTS-HD via bitstream. That, you need 1.3 for. Since HDMI’s inception, it’s always been able to pass 8 channel 192khz/24 bit but the boys at HDMI add that if you want your AV receiver to perform the decoding INSTEAD of your source such as a Blu-Ray player, 1.3 will be necessary. DTS agrees.

Hi Mulder -- Yes, you'll get the 'core' DTS signal at 1.5m/s over optical from any player (as long as your settings are right). It's what I'm set up for with my older receiver and it sounds really good. Your other option is to get a player that decodes internally and has 5.1 analog out (assuming your receiver has 5.1 analog inputs). If my PS3 did this I would be in heaven. HOWEVER, I'm not aware of Any players that currently decode DTS Master Audio (maybe a few decode DTS-HD, but hardly any movies use just the 'HD' -- FOX etc use DTS-HDMA).

It's good to look at the specs on the source equipment. Some players may not be capable of outputting 6 channel out the optical. Isn't that the case with the PS3?

the panny does DTS HD high resolution, not DTS HD Master, via analog outs... It stills sounds amazing though.
