A number of original BBC Domesday AIV LaserDisc sets have been archived in the Internet Archive. These images are LaserDisc samples created using the Domesday Duplicator and suitable for decoding using ld-decode.
All images have been captured using calibrated equipment and, where multiple copies are available, can be median-stacked to produce high-quality video, audio and data.
