The AT-141 board also performs the audio signal processing such as the D/A conversion of the MIC
audio signal coming from the camera, the A/D conversion of the PGM signal, the A/D and D/A conversions of the INCOM audio, and the INCOM line switch with the external device. The AT-141 board
also performs interface processing of the TALLY signal.
The AT-141 board has an internal SG circuit for the HD and SD signal, establishes genlock between the
HD and SD, and also genlocks the system with the main reference that is input from the external source.
. PS-587 board
The PS-587 board is the power regulator that supplies +1.5 V and _2.0 V regulated powers that are
used for processing the serial data of the HD and SDI systems.
. RX-53 board
The RX-53 board is the interface board that has the function interface between the HD-SDI optical
signal and the camera head. The RX-53 board also performs the O/E and E/O conversions.
. DPR-163 board
The DPR-163 board interfaces the various signals with the camera head.
As to the HD video signal, it performs the processing of the two HD video channels of both the camera
picture and return picture. The processing includes the phase adjustment using the line memory and
exchange of the clock signal with another desired clock.
The DPR-163 board has a built-in color bar generator and performs the processing of the marker and
skin gate for the monitor.
It also performs embedding of the prompter signal into the signal of the return video signals and the
interface processing with the digital audio system.
. SDI-54A/SDI-82 board
The SDI-54A/SDI-82 board is an interface board for interfacing with the coaxial HD-SDI signal
supplied from external equipment.
It supplies the main line output signal, the monitor output signal and accepts the return (four systems) input,
the main reference input and the prompter input.
. RC-86 board
The RC-86 board performs the SD-conversion processing of the main line system HD signal and also
performs the HD-conversion processing of the SD signal of the return system.
As the interface with external equipment, it performs processing of the component SDI format signal.
The RC-86 board has a built-in color bar generator and a simplified composite encoder. These are used
to generate the composite analog signal for which the marker and skin gate processing has already been
performed, which are the two types used for monitoring.
. DIF-102 board
The DIF-102 board is an interface board used for interfacing the coaxial HD-SDI signal with external
equipment.
It accepts the SD-SDI main line output and the return (four systems) input, and also supplies the
composite analog output signal to be connected to the picture monitor and has a waveform monitor
control connector.

. IF-789A/789P board
The IF-789A/789P board is used in combination with the RC-86 board for interfacing the SD signal of
the main line using an analog interface.
It has a built-in digital composite encoder and color bar generator that are used to generate the composite output signal, the component output signal and the monitoring output. It also performs D/A conversion of these signals.
It has a return signal processing block that converts the analog composite input signal into the 4:2:2
digital component signal and interfaces it with the RC-86 board.
In addition, it has a built-in external sync circuit of the SC (sub-carrier).
. VDA-57 board
The VDA-57 board is an interface board that interfaces the SD analog signal with external equipment.
It supplies the composite and component SD analog signal, the monitor output, and SD-SYNC output,
and accepts the return input signals (four systems).

1-3. Circuit Description
1-3-4. HKCU-903
. FC-83 board
The FC-83 board is a frame conversion board that converts a 24P picture into a 60i picture using the 2
to 3 pull-down method.
The FC-83 board has three built-in converter circuits in total (two circuits for the main output and for
the circuit board in the bottom shelf of the main line system, and one conversion circuit for the return
system picture). In the return system circuit, the return signal undergoes reverse-conversion of that of
the main line signal.
The board is equipped with a monitor output for outputting the signals that have already undergone the
marker and skin gate processing to be used for monitoring.
It also has an auxiliary reference input circuit for operating at multiple frame frequency. The auxiliary
reference input circuit detects the frame sync point of both the main reference and sub reference
signals, and establishes the frame lock of the sub reference signal with the main reference signal.
. SDI-54B board
The SDI-54B board is an interface board that interfaces the coaxial HD-SDI signal with external equipment.
It supplies the main line output signal and the monitor output signal. It accepts the return (four systems)
input, sub reference input and supplies SYNC (two systems) output.

The LC-41 board is a line conversion board that converts the 1080-60i or 540-60P picture into the 72060P picture. It contains two converter circuits (for the main line system and return system). In the return
system circuit, the return signal undergoes reverse-conversion of that of the main line signal.
. SDI-54C board
The SDI-54C board is an interface board that interfaces the coaxial HD-SDI signal with external equipment.
