A method for generating an overlay directory for a video signal, the method comprising employing a computer having stored thereon computer-executable instructions for: displaying static images of candidate objects on a screen; assigning for each of said static images a respective index with an initial value; initializing an interruption period; producing a display of said video signal on said screen; in response to pointing to both a position within each of selected appearances of an object image in said display and a respective static image: entering information relevant to said object image in a specific section of said overlay directory provided that a particular index corresponding to said respective static image equals said initial value; determining, for each appearance of said object image, a pointing time based on said interruption period and a current time indication at which said computer detects said pointing; interrupting said display; determining respective coordinates of a spatial contour overlapping said object image; entering said pointing time and respective coordinates in said specific section; updating said particular index; resuming said display; and increasing said interruption period by a time gap between said interrupting and said resuming.
