Block Diagram Overview
(JKIB Assembly)
All inputs Video and Audio (Composite, Component Beta or SMPTE,
S-Video, DV, Balanced and Unbalanced Audio) enter and pass
though the JKIB assembly and enter the AVIB assembly. If using the
composite input in through mode the unprocessed audio and video
pass back directly to the JKOB output assembly for monitor viewing.
(AVIB)
Video and Audio signals entering the AVIB assembly are subject to
analog to digital conversion, time based correction and digital noise
reduction will be added if selected by the user. On this assembly the
signals next are MPEG encoded and sent out to the PCIB assembly.
(PCIB)
The two main functions of the PCIB assembly are.
1. RS422 control interface.
2. PCI interface for the MPEG encoded signals.
Output signals from this board enter the PC Mother board (PCI slot 3)
(DECB)
The DECB assembly receives its input from the PC Mother board
(PCI slot 2) into its PCI interface conversion IC. After conversion back
to a MPEG stream the signals pass through the MPEG decoder and
digital to analog converters for both audio and video. At this point the
analog video and audio output to the JKIB assembly.
(JKOB)
The JKOB or jack panel output board receives input audio and video
signals from the JKIB assembly. In turn it outputs directly to the back
panel.

Block Diagram Overview
(PC Mother Board)
The main circuit board assembly in this device is a very high quality
Pentium based personal computer main board. It interfaces directly
with the front panel control by an RS232 connection on COM 2. In
addition it has front and rear USB ports, a RS232 connection for a
UPS, 3 PCI slots (2 used), an Ethernet connection and VGA output.
Main system processor (Intel Celeron 2 GHz) with 256 Mb ram.
(ATX Power)
The ATX power assembly is similar to a home or office PC supply. It
provides +12, -12, +5, -5 and +3.3 voltage supplies to the PWRB
assembly.
(PWRB)
This main power supply assembly provides DC supply to all circuit
boards and drives 3 of the 5 fans used in this product.
(JKDB)
This assembly contains the RS422 interface and output RS422
connector. It also interfaces the external sync input to the DECB
board and the LTC (linear time code) to the PCIB board.
(422IB)
The RS422 input connector assembly provides input to the 422 driver
IC located on the JKDB board.
(HPVB)
Headphone output volume and driver assembly. Located on the front
panel.
(FLKB)
Front panel assembly. This board includes the florescent display
driver and IR remote control decoder. This board along with its main
CPU communicate directly to the PC motherboard through the RS232
Com 2 port.
