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!

    I took the ADV7625 SW manual and compared it with the ADV7623 Manual. The register functions are not similar.

    Addr. OSD 0x10: ADV7625-->osd_Transparant_colour,  ADV7623--> OSD_Filled_Box_enable
    Have only seen that OSD Addr. 0x09 - 0x0f are not defined.

    Also tried to change reg. OSD(0x0c) like described by you, without any effect.

    Kind regards
