ABSTRACT:
A compact disc-like display device is adapted to display a sequence of pictures which jointly represent a full-motion video scene, which picture sequence is digitized by means of some suitably chosen encoding algorithm. The digitized picture sequence comprises a series of video blocks. Since the disc continues to rotate at the normal speed when the picture sequence is displayed in slow motion, or in the case of a freeze, discontinuities in the display of the picture sequence are produced. To inhibit this, a header referring to a predetermined video block, preferably the next block, is associated with each video block so that the display device has information about that picture which is to be displayed next. The display device searches, reads and processes the associated video block on the disc.
