8.11.10 Attribute
The attributes (flash, underline, italic) are controlled to the character
font. The attributes to be controlled are different depending on each
mode.
CC mode .................... Flash, underline, italic for each character
OSD 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 di-
rection 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 is con-
trolled by RC15 of OSD RAM. The ON/OFF for flash is controlled
by bit 3 of the OSD control register 1 (refer to Figure 8.11.3).
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 V
SYNC
count.
<NTSC method>
·
V
SYNC
cycle
48
≈
800 ms (at flash ON)
·
V
SYNC
cycle
16
≈
267 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 of attribute is shown in Figure 8.11.30. 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 thepre-divide ratio = 2, the italic character
with slant of 1/2 dot
10 steps is displayed (refer to Figure 8.11.30
(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 8.11.31).
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 8.11.31).
7:
When displaying the 32nd character in the italic and when solid space
is off (OC14 =
“
0
”
), parts out of character area is not displayed (refer
to Figure 8.11.30).
