• Metadata Embedding Embedded Metadata Output enables SMPTE 2020-1 metadata

embedding in the SDI video output, as selected using controls described

above.

Embedded Output Line allows selection of SMPTE 2020-1 metadata

line

location within the VANC space for re-inserted Dolby

metadata.

(Range is 9 thru 41)

Note: • Although the output line drop-down will allow any choice within the

9 thru 41 range, the actual range is automatically clamped (limited

to) certain ranges to prevent inadvertent conflict with active

picture area depending on video format. See Ancillary Data Line

Number Locations and Ranges (p. 3-9) for more information.

• The card does not check for conflicts on a given line number.

Make certain the selected line is available and carrying no other

data unless existing metadata is to be intentionally overwritten.

Typically, when encoding is active it is recommended that any

metadata not specifically related to that being used by the

encoder be removed (or replaced with metadata being used by

the encoder), and also that the line number be set to overwrite

obsolete input VBI metadata. Also, the encoded pair carries the

up to date metadata within the encoded pair stream. Removing or

replacing obsolete metadata avoids any ambiguity of having

different metadata packets on multiple lines, or metadata that is

not related to the encoding being performed.

In this example, the on-card Dolby encoder is to receive external metadata over serial port B. Also, the new metadata from the

on-card decoder is to be inserted into the SDI output SMPTE 2020 VBI and exported from the card over serial port A.
