Abstract
Method and apparatus for enabling a user of a video laser disc to interact with the video image being displayed so as to provide capabilities which are either not available or difficult to implement using prior art techniques. An example of the use of the present invention would be to enable a user, while viewing a music video or movie, to be presented with a menu specifying choices which the user may make wherein the next program played is an item from the menu selected by the user. A branch table is encoded within what is known as a subcode channel of a laser video disc, which table is loaded into a memory and specifies information which identifies segments on the laser video disc to which the playback head of the laser video disc should go when a particular control button is pressed on a remote control.
