METHOD AND APPARATUS FOR NAVIGATING THROUGH A VIDEO SIGNAL

摘要

Circuits (1) for navigating in a user- friendly way through video signals comprising shots and scenes shots are provided with shot boundary detectors (3) for detecting shot boundaries between shots and with scene boundary detectors (2) for detecting scene boundaries between scenes and with controllers (4) for controlling the boundary detectors (2,3) for said navigating. Scene control parts (42) control the scene boundary detectors (2) for finding one or more shots at the start or at the end of a particular scene and shot control parts (43) control the shot boundary detectors (3) for finding a particular shot. Direction control parts (44) control the scene control parts (42) for detecting scene boundaries in one of two opposite directions and control the shot control parts (43) for detecting shot boundaries in the other one of the two opposite directions. Output parts (71-73) of output interfaces (7) provide first images of first shots and second images of second shots for being displayed simultaneously. Selection control parts (45) select the first and second images.
