A system and method which displays a graphical icon, such as a slider bar, on a subscriber's television or display unit for indexing to different positions in a video stream in an interactive video delivery system. The interactive video delivery system preferably comprises at least one media server which stores one or more video streams, and one or more subscribers which each include a display device, such as a television. The television displays a slider bar or other graphical icon, and the slider bar is used to index to different locations in the video stream. During video delivery, the user may use or adjust a knob on the slider bar, preferably using a remote control device, to indicate a desire to "jump" to a different location in the movie or video stream. The media server receives the slider bar user input from the subscriber device and begins outputting the normal play stream at the desired position. |

DETAILED DESCRIPTION The present invention comprises a system and method which displays a graphical icon, such as a slider bar, on a subscriber's television or display unit for indexing to different positions in a video stream in an interactive video delivery system.
The interactive video delivery system preferably comprises at least one media server which stores one or more video streams, and one or more subscriber units which each include a display device, such as a television.
A set top box or other device used with each television displays a slider bar or other graphical icon, and the slider bar is used to index to different locations in the video stream.
In the preferred embodiment, the media server stores normal play streams, and may store one or more corresponding trick play streams, i.
e.
, fast forward and/or fast reverse video streams, for each of the normal play streams.
In the preferred embodiment, the media server stores normal play video streams which are preferably compressed using any of various types of video compression methods, preferably an MPEG method.
The system of the present invention generates an index table or look-up table for each normal play stream which enables indexing to different positions in the stream.
In creating an index table for a normal play stream, the system first analyzes the normal play stream and preferably creates a normal play time standard based on presentation timestamps comprised in the normal play stream.
The system then preferably creates an index table or look-up table for the normal play stream using the normal play time standard.
Each index table comprises an array of two-tuples, wherein the two-tuples are the normal play time standard and an index or offset into the respective stream.
The index tables enable indexing to different locations in the stream.
If the media server stores trick play streams, the system also preferably creates index tables for the trick play streams which enable indexing between the normal play and trick play streams
