ABSTRACT:
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.
