Abstract: A method for navigating through video matter by means of displaying a plurality of key-frames in parallel, whilst allowing selective accessing of displayed keyframes for thereupon controlling actual access to said video matter as representing a mapping of so accessed keyframes, said method being characterized by allowing within a single user interface organization to select between a first operative mode for arranging keyframes in a temporally ordered manner on the screen and a second operative mode for arranging keyframes with multiple selectible granularities between contiguous keyframes as displayed.

Abstract: The invention aims at recording a data reduced digital video signal on a longitudinal record carrier (40) by a recording apparatus of the helical scan type. The apparatus is adapted to generate signal blocks of information of the trick play video signal and to generate signal blocks of information of the data reduced digital video signal. A signal block of information of the data reduced digital video signal comprising a first frame (I-frame) and at least one second frame (B- or P frame) of the data reduced digital video signal. The apparatus is adapted to record each time after each other a signal block of information of the digital trick play video signal and a signal block of information of the data reduced digital video signal on the record carrier. A signal block of information of the trick play video signal is recorded in n subsequent tracks (T.sub.2) on the record carrier, where n is a constant integer for which holds n.gtoreq.
