5.8 SCALER
The scaler of S5D4100X runs in the following 4 image scaling modes. (1:1 mode is Scale Up.)
5.8.1 HUPVUP (Horizontal-Scale-Up, Vertical-Scale-Up)
For ITU-R.656/601 input, the scaler guarantees clock speed of 80MHz to XGA output. The scaler supports scale-
up of up to 1024 pixels in horizontal direction, and up to 768 lines in vertical direction. The scaler supports scale-
up at different ratio in H/V direction respectively.
5.8.2 HDNVDN (Horizontal-Scale-Down, Vertical-Scale-Down)
For ITU-R.656/601 input, the scaler supports scale-down to 1/2 size. For NT input, the scaler supports scale-
down of up to 360 pixels in the horizontal direction, and up to 120 lines in the vertical direction. The scaler
supports scale-up at different ratio in H/V direction respectively.
5.8.3 HUPVDN (Horizontal-Scale-Up, Vertical-Scale-Down)
For ITU-R.656/601 input, the scaler supports scale-up of up to 1024 pixels in the horizontal direction, and scale-
down of up to 1/2 in the vertical direction. For NT input, the scaler supports scale-up of up to 1024 pixels in the
horizontal direction and scale-down of up to 120 lines in the vertical direction.
5.8.4 HDNVUP (Horizontal-Scale-Down, Vertical-Scale-Up)
For ITU-R.656/601 input, the scaler supports scale-down of up to 1/2 in the horizontal direction, and scale-up of
up to 768 lines in the vertical direction. For NT input, the scaler supports scale-down of up to 360 pixels in the
horizontal direction, and scale-up of up to 768 lines in the vertical direction.
5.9 OSD (ON-SCREEN DISPLAY)
OSD stores the Font RAM address and the font features in the Display RAM, displays the font and its features in
the designated location, and displays the features designated in OSD register on the screen.

Figure 17. OSD Font Structure
OSD font is configured with 12*18 (W*L) pixels, and is divided into character and raster when displayed on the
screen. Font color can be controlled with FC of Display RAM, and a font has 16 kinds of character color and 16
kinds of raster colors. FC value is used as the reference of LUT for controlling of character and raster.
