Description
Embedded Audio may be inserted in the ancillary data space of the SD, HD, and 3Gb video
outputs.
SD, HD and Level A 3Gb: 16 channels in 4 groups in each link; 8 AES/EBU audio pairs.
Level B 3Gb: 32 channels in 4 groups in each link; 16 AES/EBU audio pairs.
10 Hz to 20 kHz in half Hz steps.
-60 to 0 dBFS in 1 dB steps.
ATC-LTC and ATC-VITC can be inserted in the signal as a user-defined time or, if Option GPS
is present, the timecode can be the time of day of the GPS or GLONASS signal.
Arbitrary Type 2 ANC data packet with user selectable DID (8 bits, 01h-7Fh), SDID (8 bits,
01h-FFh), Data Count (DC) (numeric, 0-255 words), User Data Words (UDW) (hex, 0-3FF per
word). Number of editable words in string indicated by DC value. User specifiable location (for
example, HANC/VANC, line number) for this packet.
SMPTE 352 Embedded Ancillary Data is placed on the video outputs as per SMPTE 425M.
