interface and receives/transmits data via I 2 C-firmware user-interface. The slicer combined with
dedicated hardware stores TTX data in a VBI buffer of 1 Kilobyte. The Microcontroller firmware
performs all the acquisition tasks (hamming-and parity-checks, page search and evaluation of
header control bits) once per field. Additionally, the firmware can provide high-end Teletext-
features like Packet-26-handling, FLOF, TOP and list-pages.
