HD to SD SDI / SD SDI to HD
Description Allows adjusting the secondary phase of the mainframe, that is
to say the relative phase of the:
• HD SDI outputs compared to the phase of the SD SDI
outputs with a 'Blackburst' genlock.
• SD SDI outputs compared to the phase of the HD SDI
outputs with a 'Tri-Sync' genlock.
This setting only applies to HD resolutions.
See "Video and Reference Settings" on page 44 for more
information on genlock type.
Values • If the Genlock type is set to ’BlackBurst’, the secondary
phase for HD to SD SDIcan be adjusted by steps of half
pixels (13.5 ns) between - 1000 ns and +1000 ns.
• If the Genlock type is set to 'Tri-Sync', the secondary phase
for SD SDI to HD can be adjusted by steps of half pixels
(37 ns) between - 400 ns and +400 ns.
Warning
• The SD phase is always adjusted according to the SDI outputs. Internal
CVBS outputs have a delay of 48 x 37 nsec compared to the corresponding
SDI outputs.
• The internal CVBS outputs cannot be used to feed directly a vision mixer or
any equipment performing video effects, since the phase of the chroma
subcarrier is not adjustable internally.
