CREATION OF DIGITAL PROGRAM PLAYBACK LISTS IN A DIGITAL DEVICE BASED ON HIERARCHAL GROUPING OF A CURRENT DIGITAL PROGRAM

摘要

Playback list creation for digital programs in a digital device utilizes navigation path used to locate a particular digital program in a hierarchally-ordered grouping of digital programs, the grouping based on organization parameters of the digital program. The playback list is created from digital programs within the navigation path used to reach the selected digital program. The playback list may be shuffle-played or played in order. Playback of a different digital program causes changes to the navigation path, which then changes the playback list. In an MP3 player, for example, ID3 tag attributes are used as organization parameters to provide hierarchal grouping of digital audio files.
