From 1982, Scottish image processing expert Donald F. McLean developed software to capture and restore the video recorded on the Phonovision discs. Analysis of the recordings by McLean revealed that serious problems had occurred during the making of the recordings, due mostly to the mechanical linkage that was necessary to allow simple playback. The problems were largely corrected by software, and the resultant images project a far better quality image than what would have been seen in Baird's laboratories at the time.
