metadata


The Dolby Laboratories, Inc. have introduced the “data about the audio data“, the Dolby metadata
which are intended to travel along with the multi channel bit stream from acquisition (point of audio
recording) to delivery (Dolby Digital decoder at home (either part of the TV / Set Top Box or the home
theater system). Those metadata may control the home equipment in a way that the sound impression is
as close as possible to what the producers intention was when mixing a movie sound track.

There is not enough room for explanation of the Dolby metadata system in a product manual like this.
We recommend to those who are not familiar with this quite complex matter, to study the many
publications from Dolby Inc. probably found here:

You can browse the Technical Library and for “Metadata”. Here you will find the
“Dolby

®

Metadata Guide” and other useful information regarding Dolby technologies as well.
