data packets are not present. Dolby E VANC packets are identified by DID: 0x45 and
SDID: 0x01 - 0x09. This alarm is enabled by SDID value.

Dialnorm : The Dialnorm alarm occurs when the Dolby E VANC metadata dialnorm
value for the enabled program falls outside selected minimum and maximum values for
the duration. If the Dialnorm Source in the Dolby Setup menu is set to VANC, the
dialnorm value from the Dolby D Essential payload is the specific dialnorm value used
for this alarm. If the Dialnorm Source is set to Dolby Decoder, the dialnorm value is
extracted from the metadata in the audio stream specified by the Input selection in the
Dolby Setup menu.This alarm is enabled by program.
