DIGITAL VCR WITH TRICK PLAY IMAGE CONTROL

摘要

A digital video cassette recorder (350) operates by the selection of predete rmined replay speeds and the allocation of specific loca tions within each track from which data may be reproduced. These specific track lo cations are utilized during recording to place advance t elevision image data for reproduction during "Trick Play" operation. The "Trick Play" image data (353) is also reproduced during normal playba ck but may not be utilized. The specific track locations are selected to facili tate "Trick Play" operation at a plurality of speeds in both forward and reverse directions. Since the advanced television signal comprises a plu rality of predicted frames, transition from "Trick Play" to normal speed replay requires a control function which is responsive to the reproduc tion, at normal replay speed, of an interframe coded fra me. Various methods of reproduced image transition are used for selecting both t o and from "Trick Play" reproduction.
