Abstract
Abstract The present invention is directed to a method for relating indexing information associated with at least two indexing schemes to facilitate the play-back of user-specified digital video data. The method includes the steps of scanning a stream of digital video data for indexing information related to at least two indexing schemes prior to being stored in a video server, and generating a mapping table in order to convert indexing information associated with one of the at least two indexing schemes to corresponding indexing information associated with another one of the at least two indexing schemes. The indexing information identifies discrete portions of said stream of digital video data so that those portions can be accessed at a later time. The mapping table may be stored in a database. A video client is also provided according to the present invention which relates indexing information associated with at least two indexing schemes to facilitate the play-back of user-specified digital video data on a video display. The video client includes a loader and a video player. The loader scans the digital video data for indexing information and loads the digital video data into a video server. The loader includes a mapper which generates a mapping table relating indexing information associated with at least two indexing schemes. The video player controls the play-back of the digital video data using the mapping table which is retrieved by the video player when digital video data is to be displayed. The video server sends the digital video data in response to the control exercised by the player to the video display for display thereon.
