ADV7623 scale text

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!

  • Hi,

    Swap RAM should be done after setting TBOX_V_SCALE and TBOX_H_SCALE value.But the font quality will decreased  when using Horizontal or Vertical scaling value,

    Hence, More than one font can be used to increase the text size programmatically.

    We can find the next word (TBOX) location by calculating the offset of the each glyphs.

    Thanks,
