5. Video Processing System
The Digital Reality Creator (DRC) is a line doubler and noise reduction
circuit for the 480i signal. The DRC up-converts the 480i signal to a 1080i
signal (High Definition Format). The DRC acts only as a noise reduction
circuit fir the 1080i signal since it is already in a High Definition format.
The IFP IC4610 takes the 1080i (from the DRC), 720p, or the 480p
(from the CCP-X IC7701) and performs the Interlace to Progressive scan
conversion, and also performs the signal scaling process to develop a
signal to equal to the resolution of the particular size LCD panels. The IFP
also performs the same process on the sub-picture signal for developing
the picture for the right pane in twin picture display mode, however, the
sub-picture is only at the 480i format resolution level.
The IFP IC4610 receives the PC Input directly on the DSU-Board. The
IFP is compatible with the VGA, SVGA, XGA, WXGA, and the SXGA
formats at the 60hz vertical frequency rate.
The properly scaled IFP output signal (1080p) on the DSU-Board is sent
to the C-board and the ROOK & LCD Drivers IC's. The ROOK IC9102
performs gamma control, and white balance control signal processing.
The LCD drivers perform the actual individual pixel control for picture
display. The SXRD panel has the full high-definition resolution of 1920 X
1080.
