Randomized playback of tracks in a multimedia player

摘要

An audio reproduction apparatus randomizes or shuffles the playback order of tracks from a prerecorded media such as a compact disc within a multiple-disc changer. Shuffle sequences are generated using a linear congruential random number generator (LCRNG). The shuffle sequence does not have to be stored since a next track in the sequence can always be generated from the LCRNG using a particular set of parameters. The parameters are determined in response to the number of track (or discs) in a sequence and include elements obtained from a lookup table and elements that are randomly selected so that the same sequence is not always generated for a certain sequence length.
