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.

Claims

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.

2. The data format of claim 1, wherein said first header includes a bit rate used for decoding said contents of said memory.

3. The data format of claim 1, wherein said first header specifies an algorithm used to encode said contents of said memory.

4. The data format of claim 1, wherein said second header includes a data field designating a category of music corresponding to one of said individual tracks of audio stored on said music chip.

5. The data format of claim 1, wherein said second header includes a data field having stored therein a code representative of an artist, said artist having a work included as a corresponding one of said individual tracks of audio.

6. The data format of claim 1, wherein said second header includes addressing information corresponding to said individual tracks of audio.

7. The data format of claim 6, wherein said addressing information includes a begin and end address for each of said individual tracks of audio.

8. The data format of claim 6, wherein said second header includes data fields of fixed widths, and wherein said addressing information includes only an end address for each of said individual tracks of audio, whereby a corresponding begin address is implied.

9. The data format of claim 1, wherein said first header includes data pertaining to distribution of said pre-recorded music.

10. The data format of claim 5, wherein said code representative of said artist includes a binary coded abbreviation of said artist.

11. The data format of claim 4, wherein said category code includes a binary code corresponding to a specific music type.

12. The data format of claim 1, wherein said at least one second header includes a data field corresponding to song titles and play times.

13. The data format of claim 4, wherein said music categories are selected from the group consisting of Classical (CLS);

Country (CTY);

Gospel (GOS);

Jazz (JAZ), Popular (POP);

Rap (RAP);

14. The data format of claim 1, wherein information included in said first and second header is automatically downloadable from said music chip upon power-up.

15. The data format of claim 1, wherein said at least one second header follows said first header and said second header includes a data field designating a music category followed by a data field designating a musical artist followed by a data field designating addressing information for a corresponding one of said individual tracks of audio.

16. The data format of claim 15, wherein said addressing information includes a begin and end address for each of said individual tracks of audio.

19. The data protocol of claim 18, wherein said global header specifies a bit rate to be used in decoding said pre-recorded audio stored in memory.

20. The data protocol of claim 18, wherein said individual header includes a data field indicative of a music category for an associated track of audio.

21. The data protocol of claim 18, wherein said individual header includes a data field representative of an artist associated with said individual track.
