We use the ADV7623 for superimpose textdata on the hd-video (1080p) . Runs perfect, but the
text is very small, so we tried to scale it with TBOX_V_SCALE and TBOX_H_SCALE, without success.
If we want to increase the text size, have we to change the font data??
Another problem occured: when we tried to show a sentence with more than 16 characters, we need to use
more "words". But how can we get the information where the first "word" ends to continue with the next one?
Thanks for your help!

Hello Poornima
I created the FLASH_ROM_CHAR data with the ADI_Character OSD tool.
