To use this library you need an additional ATMega328P to act as a video processor, and a 74HCT166 shift register to generate the video bit stream.
The video processor hex file needs to be programmed into an ATMega328P with the following fuses set:
E6 D9 FF
In avrdude that is: (change the com port as appropriate)
avrdude -P COM3 -b 19200 -c avrisp -p m328p -n
avrdude -P COM3 -b 19200 -c avrisp -p m328p -U lfuse:w:0xe6:m
avrdude -P COM3 -b 19200 -c avrisp -p m328p -U hfuse:w:0xd9:m
avrdude -P COM3 -b 19200 -c avrisp -p m328p -U efuse:w:0xff:m
avrdude -P COM3 -b 19200 -c avrisp -p m328p -U flash:w:SBCVideo.hex
The video processor code is written by Grant Searle, based on code by Daryl Rictor.
