Abstract

A method and apparatus wherein video images are recorded on a plurality of tracks of a tape such that, for playback in a search mode at a speed, higher than the recording speed the displayed image will consist of a plurality of contiguous parts, some of the parts being read out from tracks each having a different frame recorded thereon.

Claims

1. A longitudinal record carrier having a plurality of oblique tracks, digital data for creating a plurality of images being recorded on said tracks, each of said tracks having a sequence defining, on display, a first contiguous area of one of said images recorded thereon, said sequence comprising a plurality of sub-sequences each defining, on display, a second contiguous area, the second contiguous areas being lined up along a first axis, each of said sub-sequences comprising a plurality of basic segments each defining, on display, an incremental area of said one of said plurality of images, the incremental areas being lined up along a second axis orthogonal to said first axis, each basic segment consisting of blocks of coded data including a plurality of pixels defining, on display, a rectangular area of said one of said plurality of images wherein the recorded images are reproducible by a reproduction apparatus in a reproduction mode.
