2.16.10 Attribute
The attributes (flash, underline, italic fonts) are controlled to the character font. The attributes for each
character are specified by RC14 to RC16 of OSD RAM (refer to Figure 2.16.26). The attributes to be
controlled are different depending on each mode.
CC mode ................... Flash, underline, italic for each character
OSDS/P mode .......... Border (all bordered, shadow bordered can be selected) for each block
(1) Under line
The underline is output at the 23rd and 24th lines in vertical direction only in the CC mode. The
underline is controlled by RC16 of OSD RAM. The color of underline is the same color as that of the
character font.
(2) Flash
The parts of the character font, the underline, and the character background are flashed only in the CC
mode. The flash for each character is controlled by RC15 of OSD RAM. The ON/OFF for flash is
controlled by bit 3 of the OSD control register 1 (refer to Figure 2.16.3). When this bit is “0, ” only
character font and underline flash. When “1,” for a character without solid space output, R, G, B and
OUT1 (all display area) flash, for a character with solid space output, only R, G, and B (all display
area) flash. The flash cycle bases on the VSYNC count.
<NTSC method>
s When bit 4 = “0” · VSYNC cycle ! 24 ≈ 400 ms (at flash ON)
· VSYNC cycle ! 8 ≈ 133 ms (at flash OFF)
s When bit 4 = “1” · VSYNC cycle ! 48 ≈ 800 ms (at flash ON)
· VSYNC cycle ! 8 ≈ 133 ms (at flash OFF)
(3) Italic
The italic is made by slanting the font stored in OSD ROM to the right only in the CC mode. The italic
is controlled by RC14 of OSD RAM.
The display example attribute is shown in Figure 2.16.33. In this case, “R” is displayed.
Notes 1: When setting both the italic and the flash, the italic character flashes.
2: When a flash character (with flash character background) adjoin on the right side of a non-
flash italic character, parts out of the non-flash italic character is also flashed.
3: OUT2 is not flashed.
4: When the pre-divide ratio = 1, the italic character with slant of 1 dot ! 5 steps is displayed ;
when the pre-divide ratio = 2, the italic character with slant of 1/2 dot ! 10 steps is displayed
(refer to Figure 2.16.32 (c), (d)). However, when displaying the italic character with the pre-
divide ratio = 1, set the OSD clock frequency to 11 MHz to 14 MHz.
5: The boundary of character color is displayed in italic. However, the boundary of character
background color is not affected by the italic (refer to Figure 2.16.33).
6: The adjacent character (one side or both side) to an italic character is displayed in italic even
when the character is not specified to display in italic (refer to Figure 2.16.33).
7: When displaying the 32nd character (in 32-character mode)/42nd character (in 42-character
mode) in the italic and when solid space is off (OC14 = “0”), parts out of character area is not
displayed (refer to Figure 2.16.33).
