Abstract:
1. A method for identifying the contents of a compact disc, said method comprising receiving a table of contents (TOC) identifier associated with a compact disc, said TOC identifier comprising a string formed by the concatenation of a number indicative of the number of tracks on the compact disc, a series of numbers corresponding to track offsets for each track of the compact disc, and a number indicative of the lead out value of the tracks on the compact disc; parsing said string into the number indicative of the number of tracks on the compact disc, the series of numbers corresponding to track offsets for each track of the compact disc, and a number indicative of the lead out value of the compact disc; determining the first number from said series of numbers; subtracting said first number from each number in said series of numbers to form an altered series of numbers; concatenating said altered series of numbers to form an altered string that comprises the altered TOC identifier; and comparing said altered TOC identifier to a plurality of canonical TOC identifiers, each of said canonical TOC identifiers associated with a particular album, to identify the contents of the compact disc.
