Return Video Signal Input and Output
Return video signals input to this unit are sent to the
camera adaptor as HDSDI signals. The camera adaptor
switches between the return video signal received from
this unit and the signal received from the camcorder, and
outputs the signal from the MONI.OUT connector. The
XDCA-55 sends return video received from this unit to the
camcorder via its camcorder connection connector
(50-pin).
As return video signals, this unit accepts HDSDI signals,
SDSDI signals, and SD analog composite signals. HDSDI
and SDSDI return video signals are input from the unit's
