That is beside the point. The problem is not the drawing of letters, but the extraction of pixel data from a Transport Stream packets. The specification of the DVB-subtitles mentions two variants: (1) string of characters, (2) pixel colorvalues to be looked up in a 16-value CLUT. The stream I have at hand consists of pixel data in a 720x36 rectangle. Furthermore different broadcast stations use different lettertypes. Of course it would be nice if I could simply extract the letters, but for the moment this surpasses my abilities.
