Window Size: Number of Character Rows and Character Columns
3.4.1
Window Horizontal Size
The window horizontal size defines the number of characters displayed for character row for each
separate OSD window. This value is selected by bits HSW1[4:0], HSW2[4:0], HSW3[4:0] and
HSW4[4:0], respectively.
The range of the window horizontal size is from 1 to 32 characters, in steps of 1 character each.
Each character is 12 pixels long. There is an offset of 1 character.
Window Horizontal Size = HSWi[4:0] +1 characters
The default values for the window horizontal size for each of the four OSD windows is given in
Table 10
.
3.4.2
Window Vertical Size
The window vertical size defines the number of character rows displayed for each separate OSD
window. This value is selected by bits VSW1[3:0], VSW2[3:0], VSW3[3:0] and VSW4[3:0],
respectively.
The range of the window vertical size is from 1 to 16 character rows, in steps of 1 character row
each. It is important to note that the height of each character row is defined by the row height
parameter. For more information, refer to
Section 4.4: Space Lines on page 21
. There is an offset of
1 character row.
Window Vertical Size = (VSWi[3:0] + 1) x Row_Height (in scan lines)
Row_Height = Character_Height + 2 x Space_Lines
The default values for the window vertical size for each of the four OSD windows is given in
Table 11
.
