Clears current text, displays text message over video (default) or blank
background. The built-in character generator can accept up to 40
characters of text (including carriage returns), 28 characters per line. Use
a hex $0D or decimal 13 in the text as a carriage return, which will
advance CG to the next line, first space on the right.
Start Line - 1-11
Text Color - 1-7= White
Text Background Color – 0-7=Transparent (no background)
Full screen background – 0=normal insert over video, 1=blue screen
Size and Shadow – 0-3=small text with drop shadow
Time-Out – 0=15-second display, 1=persistent
Persistent text stays on screen until the next DM, or new Menu or channel.
Ex1: “$A5,,10,„DM‟, 2,7,0,0,1,0,‟TEST‟ ” displays the word
TEST on the second line, white text, inserted over video, small size with
drop shadow, and timing out after 15 seconds.
Ex2: “$A5,,2,„DM‟ ” clears on-screen display, also clears
persistent text
The IRC and VDC use white text and clear backgrounds when it receives a
Text or Background Color parameter between 1 and 7, and accepts values
0-3 for text size and shadow. This allows compatibility with Smart TVs
