Linear Acoustic AERO.one V3 User Guide
4.5.13 SDI Out Destination (Channels 1-16)
Selects source of audio for re-embedding into an applied SDI signal. Choices are Mute,
AES (corresponding pair), and any of the SDI pairs. This menu can be used as a router or
pair shuffler within SDI.
4.5.14 Metadata Setup
The AERO.one has been designed to take best advantage of metadata. The incoming Dol-
by or Dolby-compatible metadata stream is parsed on a program-by-program basis, and
the dialog loudness and audio coding mode (channel count) parameters are used to scale
processing and control upmixing respectively. Setup of metadata can be accomplished in
the AERO Setup -> I/O menu.
AERO.one Metadata Setup Procedure:
•
Source: RS485/VANC- Selects between the RS-485 serial metadata input and meta-
data extracted from the Vertical Ancillary (VANC) of an applied HD-SDI signal. For
VANC metadata there are several other settings:
•
•
•
•
•
•
•
MD = 2/0 Pgm Sel: Describes which consumer metadata program will be used to
control the processing. Default and most common is Pgm 1 and this is the default.
•
MD = 2/0 Function: Describes what will be controlled when the selected metadata
program has an audio coding mode (acmod) of 2/0. Selections include:
VANC MD is Async: Disabled for standard VANC metadata, Enabled for
CBS-style VANC metadata. Default is Disabled.
VANC MD DID: Selects the Data ID of the metadata signal in hex. SMPTE
RP2020 recommends this value be set to 0x45. Currently CBS network uses
0x50 but will be changing to 0x45. Default is 0x45.
VANC MD SDID: Selects the Secondary DID of the VANC metadata signal
in hex. SMPTE RP2020 recommends this value be set to 0x01 and this is the
default.
VANC MD Line: Selects the video line to extract VANC metadata from.
SMPTE RP2020 recommends that metadata be inserted on Line 9, but we have
seen a great deal of variation, thus the default is Auto.
Pri MD Pgm Sel: Selects the source for metadata for the Primary program.
Default is Pgm 1 (i.e. in a 5.1+2, Pgm 1 is the 5.1).
Sec MD Pgm Sel: Selects the source for metadata for the Secondary program.
Default is Pgm 2 (i.e. in a 5.1+2, Pgm 2 is the 2.0).
