SDI7 module
ID TEXT submenu
Use this menu to
create text or to select a text file that will be overlaid on the
output test signal, and to set the display position of the text.
NOTE. You can store overlay functions, including text, in the mainframe presets
so that the overlay is restored on power up.
Displaying Text. To display a text overlay using the ID TEXT submenu, you
need to either enter a text string or create a text file (.txt) and download it to the
SDI7/TEXT
folder using FTP. The instructions for using FTP are located in the
How to transfer u ser files using FTP section of this manual. (See page 2-67.)
When the s
tring is entered from the front panel, it is limited to 30 characters in
length, and may contain only s tandard ASCII characters. When a text file is used,
any Unicode character supported by the default font can be displayed. The text
file can be encoded as plain 7-bit ASCII text, or UTF-8 encoding when extended
Unicode characters are used. T he text file can also include embedded newline
characters to create text overlays spanning multiple lines.
Font Files. The SDI7 module uses a TrueType font to render text overlays; the
default typeface is Deja Vu Sans. The font file is named “default.ttf” and is stored
in the SDI7 directory of the TG8000 mainframe memory.
The SDI7 module supports Latin, Cryillic, Greek, and symbol character sets for
use with the text overlay. Using FTP, you can download an alternate TrueType font
file. Make sure that the font file is renamed to “default.ttf” and that the TG8000 is
rebooted for the new font to take effect. The instructions for using FTP are located
in t
he How to transfer user files using FTP section of this manual. (See page 2-67.)
TheoriginalDejaVuSansfile can be recover ed from the TG8000 SW Library
an
d Documentation DVD if necessary.
