ABSTRACT:
The disclosure relates to a television titling apparatus which is substantially the same as a conventional television titling apparatus designed for left-to-right character presentation, but includes a novel subsystem and method which can be utilized to effect display of characters from right-to-left for languages which so require. Reverse image stroke representations are stored in a stroke generator. An auxiliary storage is provided for storing a scanline of stroke bits from the stroke generator. Scanlines of stroke bits are read out of the auxiliary storage in reverse order from the order in which they were read in; i.e., on a last-in-first-out basis. Preferably, the auxiliary storage includes first and second stores which are alternately operable to read in and read out successive scanlines of stroke bits so that one scanline of stroke bits is being read out while the next scanline of stroke bits is being read in.
