Reworked[edit]

I've moved the list of films to it's own article. I also moved the "8 channels is wierd" comments. SDDS is emulating the 70 mm magnetic format(s) which used 5 stage channels. I've also removed the Bluray speculation. Megapixie 03:34, 3 December 2005 (UTC)

Use of "to date"[edit]

I'm new to the backstage side of Wikipedia, but shouldn't phrases like "Out of the 1,400 plus films mixed in SDDS, only 97 of them to date have been mixed to support the full 8 channels" be given a date instead of the using the ambiguous "to date"? MRJayMach (talk) 09:34, 13 August 2008 (UTC)

effective bitrate[edit]

i talked to a tech with moderate knowledge of equipment (or maybe a manager). the total bitrate sounds familiar (i recalled 2-3mbit), but i thought i read somewhere that the usable bitrate was lower than that (somewhere around 700kbps) after the redundant/parity/ECC data was stripped away (because the edge of the film got destroyed the quickest/easiest). does this ring a bell with anyone? Plonk420 (talk) 11:00, 18 December 2008 (UTC)

this study pushes me towards 700kbps as it says a MiniDisc, which uses "5:1" compressed ATRAC, is about 300kbps for 2 channels of audio. 5 channels is 750, plus the sub. it MIGHT use "similar audio" between channels (joint-stereo/intensity stereo in the MP3 world). again, that 700kbps is "what comes to mind," not a number a stand by. some clairification on this subject would be nice.

References[edit]

The only citation listed in this article is a list of SDDS movies; no other references are given for the myriad of claims made within the article. If anyone out there knows where reliable reference sources might be found for this article, please get right in and add them! Without good references, this article is unfortunately filled with a wealth of great information that is unsourced and may be challenged and removed.

Still the best[edit]

Wow I didn't realize how old SDDS was, it started back in 1993, almost 20 years ago. I wonder why 10.2 or something similar is not catching on. Is it presumable that 7.1 is "enough" and or is it just not practical to mix over 10 channels? Daniel Christensen (talk) 01:20, 14 April 2010 (UTC)
