Up convert playback of SD clips containing closed caption data
When you up convert and play SD clips, EIA-608
compliant closed caption data in the clips is converted to
EIA-708 format, and then played and output according to
the EIA-708 standard.
However, settings are required for output of EIA-708
standard closed caption data by up convert playback.
Cross convert playback of HD clips containing closed caption data, and down convert playback
When you cross convert and play 1080 or 720 clips, EIA-
708 compliant closed caption data recorded in the clips is
played and output with no changes. By performing down
convert playback, you can also play and output EIA-608
standard closed caption data.
However, settings are required for output of EIA-708
standard closed caption data.
For details, see “To record and playback EIA-708-B
standard closed caption data in HDSDI signals”
(page 155).
