-35- ABSTRACT A video amusement system in which a player must direct his craft along branching paths and the corresponding scenery ahead of the craft, as observed from the vantage of the craft's cockpit, is displayed on a scree. To eliminate discontinuities in the display of the scenery, the successive frames of scenery sequences corresponding to parrallel branching paths are interleaved. This allows the read head of the videodisc reader to read the frames of a praticular sequence without skipping more than a few tracks at a time, where on the skipped tracks are recorded the frames of the scenery sequences corresponding to parallel branching paths not selected by the player. In the first preferred embodiment the fields of each frame are recorded on opposing 180° portions of adjacent track, not successively on a 360° portion of track. The videodisc is read by skipping tracks during the blanking interval at the end of each field, in accordance with the fast forward mode. In the second preferred embodiment, the field of each frame are recorded in succession on a 360° portion of the track. In this case, the video disc is read by skipping tracks during the blanking intervals at the end of each frame.
