Overview

Functions of the BKPF-206/206R

The BKPF-206/206R is a video/audio demultiplexer
board that demultiplexes digital audio signals from a
multiplexed 4:2:2 component or 4fsc NTSC composite
serial digital video signal and directly converts the
demultiplexed audio signals to analog audio signals.
With a single BKPF-206/206R board, separation of
audio signals of 4 channels is achieved.
For a 4:2:2 component serial digital signal, a total of
16 channels can be extracted by connecting four
BKPF-206/206R boards in parallel or cascade.
Serial digital video signal selection
Switching between 4:2:2 component and 4fsc NTSC
composite is achieved via the internal D1/D2 (SDI
signal selection) switch on the board.
Note
Because of the limited space to indicate the signal
formats, 4:2:2 component is referred to as "D1" and
4fsc composite as "D2" in the indications on the board.
Demultiplexing audio group selection (with
4:2:2 component serial digital video signal
selected)
For a 4:2:2 component serial digital video signal, an
audio signal group of 4 channels (group 1: channels 1
to 4, group 2: channels 5 to 8, group 3: channels 9 to
12, group 4: channel 13 to 16) to be extracted can be
selected with an internal switch on the board.
The demultiplexed digital signals are converted and
output from the ANALOG OUT AUDIO connectors as
4-channel analog audio signals.
Function selection for channels 3/4
Audio signals of channels 1/2 (5/6 in group 2, 9/10 in
group 3, or 13/14 in group 4) can be duplicated to
channels 3/4 (7/8 in group 2, 11/12 in group 3, or 15/
16 in group 4) with an internal switch setting.
Using this function, you can obtain the same signals
from the ANALOG OUT AUDIO connectors 3 and 4
as those from the connectors 1 and 2 even when only
the audio signals of channels 1/2 (5/6 in group 2, 9/10
in group 3, or 13/14 in group 4) have been
multiplexed.
