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 differe

nt 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 c

ycle bases on the VSYNC count and is

selected by bit 4 of OSD control register 3.

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.

e display example attribute is shown in Figure 2.16.30. 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

2.16.30 (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 2.16.31).

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 2.16.31).

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

.31).

8: When use the italic character which the pre-divide ratio = 1, do not use the character in which dot data

exists for the right end of a font.
