Common to HKCU-HB10 and HKCU-HB15
SDP-16 board
The SDP-16 board processes main-channel signals sent from the camera, HD TRUNK video signals,
return signals to the camera, and the HD PROMPTER signal. This board converts the main-channel serial
optical signal sent from the camera from optical to electrical signal and from serial to parallel signal.
Then, this board separates the digital audio signal and the commands multiplexed with the main-channel
signal Link A, and sends the main-channel video signal Link A to the DRX-5 board in slot 1, the main-
channel video signal Link B to the DRX-5 or DRX-8 board in slot 2, the digital audio signal to the AVP-6
board, and commands to the AT-167 board.
Also, the return video signal is sent from the DTX-5 board, the digital audio signal from the AVP-6 board,
and commands from the AT-167 board. Then this board multiplexes the digital audio signal and the com-
mands with the return video signal. Furthermore, the signal is multiplexed with the return signal and the
HD PROMPTER signal. The multiplexed signal is converted from parallel to serial signal and from
electrical to optical signal, and sent to the camera as the serial optical signal.

DRX-8 board
The DRX-8 board processes the main-channel signals from the camera.
. 3G-SDI/HD-SDIoutput
. Conversion (1080P Format → 720P Format) function as necessary
. Frame conversion function as necessary
. Down-conversion function as necessary
. Has the built-in 3G-SDI/HD-SDI signal color bar generator and supports multiple formats
. Phase adjustment and re-clocking using line memory
. Matches the MIC signal from the camera to the delay of the video signal, and then multiplexes it to the
SDI signal.
. Analog character output
HIF-57 board
The HIF-57 board has the coaxial connector for outputting the 3G-SDI/HD-SDI signals to external de-
vices.
It outputs two systems of the main-line system 3G-SDI/HD-SDI signals sent from the DRX-8 board, and
outputs two systems of the monitor-system 3G-SDI/HD-SDI signals.
