A video player, specially adapted to accommodate 'mixed field and frame' recordings, incorporates a frame store for playing back still pictures recorded on a magnetic disk as either single field or dual field (full frame) video signals. A repetitive, interlaced output signal is taken from the frame store either directly or through an interpolation circuit. While interpolation benefits single field playback, it is particularly useful for incrementally achieving full frame playback: An interpolated frame is provided for displaying a single field recording and for displaying a still picture before--and until--the second frame of a full frame recording is fully available from the frame store. Once both fields of the picture are stored in the frame store, then and only then is the disk drive motor turned off, albeit that an interpolated frame is displayed before this occurs.

Dual access frame store for field or frame playback in a video disk

A method is provided for establishing an electronic picture file composed of pictures prerecorded on a plurality of video disks that are disposed in a multi-disk video player. The arrangement and content of the picture file is determined by an editing procedure that specifies a plurality of attributes, such as image category, picture order, time allotted for viewing each picture, text to accompany each picture, and the like. The task of specifying these attributes is made manageable by partitioning the editing procedure into several levels, each level standing alone and undertaken separately as a complete, but simplified, editing procedure that produces an edited picture file ready for viewing.
