Teletext Experimenter’s Board

A Teletext decoder and RGB display board based around the Philips SAA5246 Teletext decoder IC. This board can:

  • Decode teletext from a composite-video carrier
  • Display it on an RGB monitor
  • Allow you to read a decoded page back to your host device
  • Allow you to substitute your own page data, making a “teletext quality” graphics card
  • Be controlled entirely via I2C!
