The nanoVTV is a scan converter board that accepts non-interlaced VGA signals at up to 2048x1536 resolution from a PC or Macintosh computer for conversion to broadcast-quality NTSC/RS170 signals.

Unlike conventional scan converters, the nanoVTV features on-board Frame Store and a DSP unit which performs scan conversion, flicker filtering, scaling and colour space conversion in the digital domain. The processed video data is sent to the digital video encoder for conversion into broadcast-quality composite and S-Video NTSC or RS170.

The nanoVTV features a board micro controller allowing it to operate completely standalone without run-time control from an external system. The settings of the card can be modified via a serial link. Application-specific configuration is able to be stored to the non-volatile storage of the card.
