Abstract: Disclosed is an audio compact disc that includes a number of audio tracks, at least a portion of which are to be played at predetermined times when the audio disc is installed in a compact disc jukebox or similar player. Stored on the compact disc is a value indicating that at least a portion of the audio tracks are to be played at predetermined times. The stored value also specifies a predetermined sequence or play schedule that is to be used with the compact disc. When the compact disc is installed in a compact disc jukebox, the stored value is accessed by the jukebox controller and causes audio tracks that are scheduled for playing at predetermined times to be played at that time or immediately after any audio track that is being played at the predetermined time.

Abstract: An apparatus and method of scheduling audio tracks on audio compact discs in a CD jukebox to be played at predetermined times is disclosed. The method includes storing, in a CD audio track index location on an audio CD, a value indicating that the audio CD is a sequence CD containing audio tracks that are to be played at predetermined times. The stored value also specifies a predetermined sequence, or schedule to use with the sequence CD. A controller computer, within the CD jukebox and external to the CD player, utilizes CD-DA commands to query the CD player for the CD audio track index on each audio CD. The responses are used to distinguish normal audio CDs from sequence CDs. A periodic interrupt invokes a sequence interrupt handler that determines whether any audio tracks on any sequence CDs are scheduled to be played.
