of the oldest Schemas, and one that perhaps needs a little
tweaking..</FONT></DIV>

<DIV><FONT face="Arial" size="2">As I see
it, there are two approaches Frank: </FONT></DIV>
<DIV><FONT face="Arial"
size="2"></FONT> </DIV>
<DIV><FONT face="Arial" size="2">You can
either add additional TEXT2= TEXT3= TEXT4= and so on to the bottom of the
OSD Message, which I would imagine will burn that ram pretty fast
(although, you could use an I2C Ram chip easily, if you go down the
picbasic route)</FONT></DIV>
<DIV><FONT face="Arial"
size="2"></FONT> </DIV>
<DIV><FONT face="Arial" size="2">The Other
would be to not clear the screen with each message, add a DELAY=0,
and use the ROW= and COLUMN= tags to display a series of messages
where you wanted on screen.</FONT></DIV>
<DIV><FONT face="Arial"
size="2"></FONT> </DIV>
<DIV><FONT face="Arial" size="2">That would
probably work best with a "clear" command of some kind, but the
OSD Schema doesn't have one at present.. lets have a think about this for a
bit.</FONT></DIV>
<DIV><FONT face="Arial"
size="2"></FONT> </DIV>
<DIV><FONT face="Arial" size="2">It's
pretty important that we get the Schema right at this point: just now we
have only a few OSD Devices (Tivo, Slimp3, VFD, and your STV) in the
future, there will be many more. It's kinda important to make sure the
schema works across more display devices.</FONT></DIV>

<DIV><FONT face="Arial" size="2">I'm
screaming busy today again, but I'll try to get something
together.</FONT></DIV>

Just some
questions regarding sending several lines of text.....The Stv???
has 11 lines to send text messages and i think 27 characters per
line which is approx 297 characters which is a lot of
ram ....Is there a need for a Number of lines to be sent as part
of the initial message and then send as several xpl messages
????</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Arial" size="2">Hope this
makes sense what im trying to say</FONT></DIV>
