Data protocol and method for segmenting memory for a music chip
DC CAFCFirst Claim
1. A data format for use in an audio system wherein pre-recorded music is digitally encoded in memory of an integrated circuit music chip, and said music is decoded and reproduced by means of an associated audio player, said data format for storing information pertaining to the contents of said music chip, wherein individual tracks of audio are stored in designated locations in said music chip, said data format including:
- first header having parameters stored therein for use by said audio player in decoding said digitally encoded music stored in said memory; and
at least one second header, said second header including selectable categorical information relating to said individual tracks of audio stored in said memory.

Abstract
A protocol for labeling various types of data contained in a music chip. The protocol includes a hierarchical arrangement of headers for storing information about selections on the chip and the method in which they were coded in the memory of the chip. A global header located at the very start of memory will specify information needed to successfully decode the content of the music chip. This will include, for example, the necessary bit rate, as well as information pertaining to a specific PAC (Perceptual Audio Coding) algorithm employed in recording audio on the chip. In addition to the global header, each chip will have a section of memory allocated to a table of contents. The table of contents will include information on play times, song titles, music category and artist. Individual track selections will be listed as part of the table of contents by individual headers. The individual header contains a music field to which a track belongs, for example, classical, jazz, country, rock, etc., an artist field, and an address field which pertains to the information for addressing each track selection. Information from the headers is self-registered or automatically downloaded when a chip is loaded into a player/juke box device. The concept of self-registering general information included within the headers allows a user to select by type of music, artist, etc. for music selections made over a period of time. In addition, the present invention provides a method for segmenting memory in an integrated circuit chip wherein the integrated circuit chip is adapted for use in an audio player and the memory has pre-recorded audio stored therein. The method includes the steps of storing in a global header parameters corresponding to encoding techniques used in storing the pre-recorded audio in memory and coding in at least one individual header data fields indicative of general description information for individual tracks of the pre-recorded audio.
