Performance of
the
FC8 (FRC) Circuit
“FC8” is a term for Hitachi’s original LSI having FRC function. “FRC” stands for Frame Rate
Converter. By using Frame Rate Converter technology for moving compensation, this circuit
creates higher picture quality and has the following function s:
1) Telecine performance (as applying “Film mode”): Judder Reduction
2) Improvement on PDP moving image by FRC from 50Hz to 60Hz.
From the perspective of hardware, this function is actuali s ed by newly mounting FC8 LSI and 3
sets of 256Mbit-DDR2 memories on the FC8 board (which is only for this function).
As a block component, the FC8 board is locate d in front of panel block. It inputs the picture signal
of the LVDS system (available: single/dual system) and then once processing the FRC as
mentioned above, it outputs the picture signal of LVDS system (available: single/dual system)
again in order to supply the panel. As the control of FC8 board, I/F of the original FC Bus system is
utili s ed.
2 power s upplies are necessary: 5.6V and 3.2V. The other necessary power s upplies are generated
on the FC8 board.
All of the above I/F are combined into 1 x 160-pin BtoB connector .
