Based on a select-from-20-speaker Digital Cinema
standard called SMPTE 429M
, Dolby, DTS, and Blu-Ray came up with a 7.1 channel concept that would allow BD content providers to mix audio in several new 7.1 speaker configurations. A touch of 'magic' in the Dolby or DTS decoder would remap
the 6.1/7.1 content decoded from the BD into any other 6.1/7.1 speaker layout the homeowner had in place. Several problems ensued:
(1) the content providers basically stuck with 5.1, and a few (re)mixes into the 6.1 and 7.1 standard
configurations, (2) the consumers (mostly) didn't understand it or want speaker layouts other than 6.1 or 7.1 standard
, and (most importantly) (3) the receiver manufacturers did not support remapping into speaker configurations other than 6.1, or 7.1 standard
Dolby seems to have said very little about the whole process (and, in any event, there are only a few 7.1 TrueHD BDs), but DTS made it something of a centerpiece in their DTS-HDMA advertising...
As always, things might be different next year...
[In any event, we will probably get the chance to be confused again, about (10.1 to) 22.2 channel audio speaker layouts related to 4th generation optical storage for movies/tv, in 7 to 10 years...?!
