Author Topic: SDDS and ATRAC Nic Margherio Film Handler Posts: 91 From: St. Louis MO, USA Registered: Dec 1999 posted 01-09-2004 12:45 PM                     The ATRAC codec has undergone much refinement since its introduction with the MiniDisc in 1992. I'm curious to know how much of this refinement can be relized by the SDDS format. Are the advancements primarily on the encoding end and thus able to benefit SDDS or is it more of a hardware issue? Are there differences between the decoding in the DFP-2000 and DFP-3000?  |  IP: Logged Michael Schaffer "Where is the Boardwalk Hotel?"

I have the specifications of the SDDS ATRAC, but when I moved to the US a few months ago, I left those documents at home. I thought I wouldn`t need them anymore since Sony dropped the format. Sorry! Sony also doesn`t fully support ATRAC anymore either. They are using more and more other encoding technologies, and had 2 new standards in the making, but I haven`t followed up on that. They planned to introduce a home standard for DVD based on SDDS (I think it was to be called SMDS), but apparently nothing came of that either.  |  IP: Logged Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 01-09-2004 10:55 PM                    So unlike Sony to drop an audio format. This is not at all like the Elcaset.  |  IP: Logged System Notices Forum Watchdog / Soup Nazi Posts: 215 Registered: Apr 2004 posted 01-04-2006 12:20 PM                 It has been 725 days since the last post.  |  IP: Logged Max Biela Film Handler Posts: 89 From: Dortmund, Germany Registered: Sep 2003 posted 01-04-2006 12:20 PM                     Hi, I don't think that the ATRAC decoding in SDDS units is something special. Take a look at the ICs inside the SDDS unit and do a search at google. In both the 2000 and the 3000 you will find ATRAC 2. Or am I missing something? Max  |  IP: Logged
