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, TP 1, -TPL, TP2, -TP2) IN A STORAGE MEDIUM (10) FOR EACH ONE OF A PLURALITY OF VIDEO PROGRAMS (PI, 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, TP 1, -TP 1, 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, TPL, -TPL, TP2, -TP2) RESPONSIVE TO A NEW REPRODUCTION SPEED; REPRODUCING (STEP 600) THE DIFFERENT ONE OF THE ENCODED SIGNALS (NP, -TP 1, 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 FIG 5
