Does Dolby plan to introduce higher data-rate versions of Dolby Digital?
While all Dolby Digital decoders are capable of handling data rates as high as 640 kbps, the 448 kbps rate used on DVDs (the maximum allowable) provides sound quality that critical listening tests have consistently confirmed as on a par with original master tapes. It would require the introduction of a new delivery format before the option to use more than 448 kb/s could even be considered.
