Composite Text Video Display
This system can generate a 25 × 40 character display on a standard television screen through the composite video input jack. The ATmega8 microcontroller-based circuit supports the NTSC and PAL standards. The efficient software uses only 3 KB of program memory, which leaves enough space for a 512-character font.
