Trick-play control for pre-encoded video

Abstract

An inventive method provides various reproduction modes by controlled selection of replay locations. Selection within a video stream or between separate video streams derived for selected trick-play speeds may be facilitated. The method allows selections to be decoded and displayed independently of previously video stream selections. The method comprises the steps of: identifying (step 200) a digitally encoded set of signals (NP, TP1, -TP1, TP2, -TP2) in a storage medium (10) for each one of a plurality of video programs (P1, P2, P+n) for reproduction of each one of said plurality of programs at a plurality of reproduction speeds; reproducing one of the encoded signals (NP, TP1, -TP1, TP2, -TP2) from the store (10) responsive to a program selection and a reproduction speed; calculating an address (step 375) for initiating reproduction of a different one of the encoded signals (NP, TP1, -TP1, TP2, -TP2) responsive to a new reproduction speed; reproducing (step 600) the different one of the encoded signals (NP, -TP1, TP2, -TP2) from the address in the store (10); and, decoding the reproduced signals for display of the selected program at the selected new reproduction speed.
