DTS specs

[Derrow]

Looking for some info on DTS audio.
I need it for the implementation into IfoEdits DVD-Authoring function.

Does anybody have seen a spec or so, anywhere?

Thanx.

Ah, viewing patents - something I know about. Although I was able to view the patent, despite the claim that the system would be unavailable until Monday.
If you are having trouble using the American patent office, try the European Patent Office, at http://ep.espacenet.com/
US patents can be viewed there (as well as most other countries) To view this patent go to the second box (view patent application) and enter "US5974380" then click "go". You will then be taken to a selection screen (which, since you were explicit, will contain only one choice)
That will lead you here: http://l2.espacenet.com/espacenet/viewer?PN=US5974380&CY=ep&LG=en&DB=EPD
The abstract, after which you can view the entire document using a pdf plugin.

Edit: I notice the USPTO left out the drawings, so I'm gathering the pdf version from EPO.

If you look again the latest specs are V1.2.1 (2002-12)

Anybody tried to use this documents? All DTS streams have a _different_ format. For example I have VERNUM=0xA when this doc desribes version 7 and nPCHS=1 that is not true...
