BKPF-L613C SDI Distributor with Analog
Monitor Out (Component)
This board distributes a component serial digital video
signals to four outputs, and converts it to an analog
signal for monitoring.
BKPF-L632 Monitoring Composite Encoder
Board
This board converts a 4:2:2 component SDI signal to
an NTSC or PAL composite analog video signal. The
unit accepts two channel signals, each of which is
divided into three and output.
BKPF-L641 NTSC/PAL to 4:2:2 Board
This board converts analog NTSC/PAL composite
video signals to 525/625-line 4:2:2 component serial
digital video signals.
BKPF-L642 4:2:2 to NTSC/PAL Board
This board converts 525/625-line 4:2:2 component
serial digital video signals to analog NTSC/PAL
composite video signals.
BKPF-L703A Analog Video Distributor
This board distributes a serial digital video signal to
eight outputs.
BKPF-L704 Black Burst Regenerator Board
This board generates a black burst signal which is
synchronized with an input signal. The board supplies
six output signals whose phase can be adjusted
between –4H and +4H continuously. Setup up to
about 40 IRE can be added.
BKPF-L723 Video Delay Distribution Board
The signal input to this board is delayed up to 1.5
µsec, and the delayed signal is supplied to up to six
output lines. The amount of delay can be adjusted in
three steps of 350 nsec, five steps of 75 nsec, or five
steps of 15 nsec, and also up to 15 nsec by fine
adjustment. Cable compensation up to 300 meters
long is also available.
BKPF-L751 Audio A/D Converter Board
This board converts the four-channel analog audio
signals to AES/EBU format digital audio signals,
which are supplied to two audio lines. The sampling
frequency is 48 kHz, and a ∆Σ-system A/D conversion
IC with 24-bit resolution is used. The signals input to
channels 1/2 and 3/4 can be supplied to either the
AES/EBU 1 or 2 output. As a reference signal, a 525/
625 video signal, an HD 3-value sync signal, or a 48
kHz word clock can be used, and the word clock signal
can be output as a reference signal.
BKPF-L752 Audio D/A Converter Board
This board converts the AES/EBU format digital audio
signals of two lines to analog audio signals, which are
output as the four-channel analog audio signals. The
sampling frequency is 48 kHz, and a ∆Σ-system D/A
conversion IC with 24-bit resolution is used. The de-
emphasis function is set to ON or OFF.
BKPF-L753A Analog Audio distributor
This board divides a pair of analog stereo audio
signals, and distributes them to four lines, or one
monaural audio signal to eight lines, and supplies the
divided signals. The gain of the input and output
signals can be selected with the switches on the board
among from –8, –4, 0, +4, and +8 dB, and it can also
be continuously adjusted with the control on the board
within the range of ±2 dB for each selected gain.
BKPF-L754 Audio Signal Generator Board
This board generates 400 Hz (or 440 Hz) and 1 kHz
signals, which are output from two output lines. The
output-signal frequency can be set for each line, and
the output signal level can be set to 0 dBm, +4 dBm, or
+8 dBm or can be controlled continuously with the
control knob.
