Abstract
A digital video cassette recorder operates by the selection of predetermined replay speeds and the allocation of specific locations within each track from which data may be reproduced. These specific track locations are utilized during recording to place advance television image data for reproduction during trick play operation. The trick play image data is also reproduced during normal playback but may not be utilized. The specific track locations are selected to facilitate trick play operation at a plurality of speeds in both forward and reverse directions. Since the advanced television signal comprises a plurality of predicted frames, transition from trick play to normal speed replay requires a control function which is responsive to the reproduction, at normal replay speed, of an inter frame coded frame. Various methods of reproduced image transition are used for selecting both to and from trick play reproduction.
