D.6.1 Universal Parameters
All universal parameters are supported by Dolby E encoders and decoders; all except
Program Configuration and Program Description Text are supported by all Dolby Digital
encoders and decoders.
Program Configuration
This parameter determines how the audio channels are grouped within a Dolby E
bitstream. Up to eight channels can be grouped together in individual programs, where
each program contains its own metadata. The default setting is 5.1 + 2. Table D‐3 shows all
the available configurations.
Program Description Text
This is a 32‐character ASCII text field that allows the metadata author to enter a description
of the audio program. For example, this field may contain the name of the program (Movie
Channel Promo), a description of the program source (Football Main Feed), or the program
language (Danish).
Note: Universal parameters include both professional and consumer metadata.Table D‐1
on page 85 distinguishes between professional consumer parameters.
