Abstract:
1. A method of generating a random number associated with a user initiated interruption of a video sequence, comprising: sequentially presenting, by a playback device, to a user a plurality of group-of-picture (“GOP”) structures of an MPEG standard collectively providing a first video sequence, each group-of-picture structure having a predetermined seed component and a navigation component, the seed component having a seed value; in response to a user initiated interruption during the presentation of a GOP structure, receiving the seed component and the navigation component from the interrupted GOP structure; providing a random number based at least in part on the seed component wherein as a user initiated point of interruption will vary from one sequence presentation to another, the varying point of interruption to receive the seed component insures a random number as the random number is derived from the sum of a predetermined value and the seed value; and linking or jumping to a second video sequence identified by the navigational component.
