3.23.4 SMPTE 2020
Audio metadata defined in SMPTE 2020 will be transferred for any video standard or format
conversion. Up to eight different packet IDs are supported on any single video field.
The ANC packets are placed in VANC on first available line from line 9 in HD/3G, from line 8
in 625i25, and from line 12 in 525i29. Note that all the SMPTE 2020 packets may not all fit in
the same line.
There will be no rerouting or change in the audio metadata, so the user must make sure that
audio routing and inserted audio from AES adhere to what is specified in the SMPTE 2020
packet.
This transfer is automatic depending on input detection and can be disabled in Multicon
GYDA.
