This is a list of some of the elements in the Dolby Status application. For a
complete list of the elements that might appear, see the Dolby Metadata Guide
available at
www.dolby.com
.
Program Description Text:
A 32-character ASCII text field used by the program
author to describe the audio program; for example, the name of the program
(Movie Channel Promo), the program source (Football Main Feed), or the program
language (Danish).
Dolby Format:
Indicates the Dolby Format. This indicator is also tied to the Dolby
Format Error/Alarm: if the Alarm is asserted, the Dolby Format is displayed in red.
Channel Mode (or Audio Coding mode):
Indicates the active channels within the
encoded bit stream, representing it in a ratio, X/Y, where X is the number of front
channels (Left, Center, Right) and Y is the number of rear (Surround) channels. If
the LFE Channel is present, an L is appended at the end of the channel mode.
Program Configuration:

Dolby E bitstream. Up to eight channels can be grouped together in individual
programs, where each program contains its own metadata.
Metadata Source:
Indicates the input from which the Dolby Content is sourced.
Dolby Data Rate:
For Dolby E it indicates the data rate that would be used to
encode a Dolby Digital bitstream.
Bitstream Mode:
Describes the audio service contained within the Dolby Digital
bitstream. A complete audio program may consist of a main audio service (a
complete mix of all the program audio), an associated audio service comprising a
complete mix, or a main service combined with an associated service. For more
information about possible values, see the instrument online help; when the Dolby
Status display is active in a tile, select the HELP button.
