C signal:U gain, V gain, HUE and Burst amplitude adjustment
Trap filter
Trap filters locate on the Y signal pass to reduce cross color interference. The trap strength is adjustable by
register setup.
Built-in color bar
This is for system test and level adjustment.
10 bit DAC with 75Ω driver
A high accuracy video DAC of 10bit is built-in. Its DAC output is able to be connected to TV input or any
image devices, thanks for its 75Ω driver built-in.
•
It mounts 16Mbit SDRAM to store multiple VGA size images. Since it has the arbitration function built-in, the
access timing from CPU for drawing can be used without any care of real-time access condition for TV display.
VGA 30fps performance can be achieved with appropriate setting of system clock, the burst size of SDRAM,
scaling ratio etc.
•
The OSD function is installed. OSD images consist of binary pixel data to display over the original image. The
Alfa-blend display is also available.
•
Scaling from
×1
up to
×4
in two independent directions, horizontally and vertically, is available.
256 step arbitrary enlargement is given by register settings. The image rotation is available when writing as well.

•
The high-speed clock for SDRAM is generated internally by built-in PLL.
•
CPU-IF with 8/9/16/18/24 bit width data transfer is available.
•
Built-in VIDEO-IF supports receiving video rate image input with Hsync/Vsync/Dotclcok signals.
It accepts various digital image formats of 18bit-RGB666, 16bit-RGB565, 16bit-YUV422, 8bit-YUV422,
8bit-YUV422 (BT656) and so on. In addition, it accepts both interlace and non-interlace format.
•
The Autoview function executes automatic writing/reading sequence. Once all the relevant commands are set, then
this function properly updates the image banks to write and to read. This bank arbitration avoids well the tearing
image (reading outruns writing).
•
The FilckerFreeFilter effectively decreases the line flicker, a substantial phenomena of the interlace method.
•
High performance C-signal band-limit filter is built-in. The thorny ‘dot crawl’ is thus decreased.
•
CGMS-A/WSS data multiple functions are built-in.
•
The I/O voltage of the CPU/Video interface is 1.6V-3.4V.
•
Macrovision™ Encoding (Revision 7.1.L1 in NTSC and PAL standards for Composite video output applications)
are built-in. (LC822973-04VM-E only)*
