Dolby E/AC-3 Metadata
Metadata (Dialnorm and Program config) information contained in a Dolby E audio stream
can be exposed on the monitor wall in text form. Dolby E and PCM audio levels can be
displayed via audio monitors. Decoding of Dolby E metadata embedded as ancillary data
(VANC) in the video stream is also supported.
• If multichannel audio (up to 8 channels) is coded in a Dolby E stream and transported
over a single AES channel, metadata and audio levels are extracted from the Dolby E
stream:
• Limited to 1 embedded audio source, selectable, no ABT support
• VU and Peak meters (8 channels), for each source
• Program config, for each source
• Dialnorm for program 1, for each source
• If multichannel audio (up to 16 channels) is transported as regular AES channels (up
to
8) in the SDI embedded audio, metadata is extracted from VANC packets:
•Program config
• Dialnorm for program 1
• VU and Peak meters come from the AES in PCM
