SYSTEM FOR PLAYING BACK A PROGRAMME RECORDED ON DISC - SHAPED RECORD CARRIER

摘要

the video disc has a spiral track in which a programe is recorded as TV signal in a sequence of two fields per turn of the track and consecutive scenes of the programe being constituted by consecutive fields. A read is provided with a control by realizing a still-picture mode where the same two consecutive fields are repeatedly read by the repeated screening of the same turn of the track.
