`ply load new recordings into the memory of each com(cid:173)
`puter jukebox.
`Another object of the present invention is to elimi(cid:173)
`nate a necessity for routemen by enabling new record(cid:173)
`ings and selection menus to be downloaded to each
`computer jukebox via a transmission link. In that re(cid:173)
`gard, it is an object of the present invention to provide
`a method and apparatus which eliminates the material
`10 waste usually associated with updating jukeboxes. In(cid:173)
`stead of throwing away old recordings and replacing
`them with new ones, as is the conventional procedure,
`the present invention eliminates this waste by enabling
`new recordings to simply be downloaded into the mem-
`15 ory of each computer jukebox. The old recordings are
`simply erased, if necessary.
`Another object of the present invention is to provide
`a method and apparatus which is capable of remotely
`obtaining jukebox usage data, thus eliminating a neces(cid:173)
`sity for routemen to do this task. The present invention
`utilizes a computer jukebox, which as part of its soft(cid:173)
`ware programming, stores the number of times each
`musical recording is played and the number of credits
`that have been awarded. This data is uploaded to a
`central control device via a transmission link.
`An additional object of the present invention is to
`provide a method and apparatus utilizing modem com(cid:173)
`puter technology to digitally store and play musical
`records. The jukebox of the present invention is basi(cid:173)
`cally a computer having a sophisticated audio produc-
`tion capability, the computer storing digitized song data
`in a computer memory. Because conventional juke(cid:173)
`boxes maintain compact discs or records in the jukebox,
`theft of the compact disc/records has been a problem,
`this problem being eliminated by the present invention's
`utilization of a computer memory to store the digitized
`song data.
`A further object of the present invention is to provide
`a method and apparatus capable of being used with the
`remote management of jukeboxes via public telephone
`lines without interfering with establishments' use of
`their own phone lines.
`Other objects, features and advantages of the present
`invention will be readily apparent from the following
`description of certain preferred embodiments thereof
`taken in conjunction with the accompanying drawings,
`although variations and modifications may be effected
`without departing from the spirit and scope of the novel
`concepts of the disclosure.
`
`This is a continuation-in-part of U.S. patent applica- 5
`tion Ser. No. 07/538,981, filed Jun. 15, 1990 now aban(cid:173)
`doned.
`
`FIELD OF THE INVENTION
`The present invention relates generally to a jukebox
`system, and more particularly to such a system includ(cid:173)
`ing one or more computer jukeboxes that can be man(cid:173)
`aged from a remote location.
`
`BACKGROUND OF THE INVENTION
`Heretofore, an assortment of musical recordings
`found in a jukebox consists of a plurality of records,
`each record containing a specific recording. Tradition(cid:173)
`ally, these records are grooved phonograph records.
`After a patron makes a selection, the selected phono- 20
`graph record is mechanically removed from a storage
`rack within the jukebox, and the phonograph record is
`placed upon rotating platform. A stylus which is con(cid:173)
`nected to a speaker system is then placed upon the rotat(cid:173)
`ing phonograph record, resulting in the phonograph 25
`record being played by the jukebox. For each selection,
`a separate phonograph record must be removed from
`the storage rack in order to be played by the jukebox.
`Conventional jukeboxes have also implemented com(cid:173)
`pact disks as means for creating an assortment of musi- 30
`cal songs. Compact disks provide the improved sound
`quality made possible by digital recordings. The same
`technique, however, is used to play compact disks. A
`separate compact disk corresponding to each selection
`must be removed from a storage rack in order for the 35
`jukebox to play the selection.
`Updating conventional jukeboxes is a costly and time
`consuming task. Routemen must periodically travel to
`each jukebox location and replace the existing record(cid:173)
`ings of each jukebox with up-to-date records. The exist- 40
`ing recordings are no longer used by the jukebox once
`removed, thus making the conventional method waste(cid:173)
`ful.
`Routemen must also travel to each jukebox location
`to keep a tally of the number of times each musical 45
`recording is selected in order to determine royalty fees.
`It is known to provide a jukebox with a counter that
`keeps track of the number of times each musical record(cid:173)
`ing is selected, but routemen must still travel to each
`jukebox location to obtain this information. Such a 50
`process requires an excessive number of people to visit
`jukebox location periodically and visually read the in(cid:173)
`formation off the counter within each jukebox. Since
`the number of jukeboxes in operation is quite large, the
`employment of routemen to obtain such data involves a 55
`considerable expense. Furthermore, the ever changing
`nature of the recording industry requires that such data
`be gathered frequently in order to keep abreast of a
`continually changing market.

`
`OBffiCTSANDSUMMARYOFTHE
`INVENTION
`Accordingly, it is a primary object of the present
`invention to provide a method and apparatus for man(cid:173)
`aging a plurality of computer jukeboxes which is capa- 65
`ble of eliminating the necessity for routemen to change
`records in the jukeboxes. The computer jukeboxes store
`recordings in memory, thus enabling routemen to sim-

`DESCRIPTION OF THE PREFERRED
`EMBODIMENTS
`In accordance with the present invention as shown in
`FIG. 1, a central management system 11 monitors and
`updates the available selection of music at a number of
`remotely located jukeboxes such as a jukebox 13. Par(cid:173)
`ticularly, the central management system 11 monitors
`each jukebox 13 to determine the number of times each
`song has been played. From these numbers, the central
`management system 11 can calculate the royalty pay(cid:173)
`ments that are due. More importantly, the central man(cid:173)
`agement system 11 can identify those specific songs
`which need to be replaced in each jukebox on an indi(cid:173)
`vidual basis, the central management system communi(cid:173)
`cating replacement songs to each jukebox 13 to update
`the available music selection therein as needed.
`Each jukebox 13 is basically a computer having so(cid:173)
`phisticated audio production capability wherein each
`computer jukebox 13 is programmed to play songs that 20
`have been digitally compressed and stored in a large(cid:173)
`volume data storage unit 93. The storage unit 93 may be
`a optical memory or any other available large volume
`nonvolatile computer memory that provides both read
`and write access.
`The central management system 11 communicates
`with each computer jukebox 13 via a transmission link
`15. The central management system 11 and each juke(cid:173)
`box 13 use respective modems 17 and 19 to maintain
`serial communication on the transmission link 15. The 30
`transmission link 15 may be a cable system such as pub-
`lic or private telephone lines or the like. However, the
`modems 17 and 19 may be replaced with RF (radio
`frequency) transceivers and associated antennas. In the
`latter instance the transmission link 15 is an RF link.
`Specifically, the central management system 11 in(cid:173)
`cludes a host computer 21 which maintains a master
`library 23 of songs and associated graphics which are
`stored in a compressed digital form in a bulk storage
`unit 25. The bulk storage unit 25 is capable of storing 40
`vast amounts of digital data, and may be take the form
`of a read-write optical storage device. The host com(cid:173)
`puter 21 indexes the master library 23 by using a master
`catalog 27 which is also maintained in the bulk storage
`unit 25.
`The master catalog 27 stores a song record 29, as
`illustrated in FIG. 2, for each song stored in the master
`library 23. Each song record 29 associates information
`in the following fields: a) a title field 31, containing the
`name of the song; b) a classification field 33, containing 50
`the type of music, i.e., country, pop, jazz, classical, etc.;
`c) a song address field 37, containing the beginning
`address in the bulk storage unit 25 of the compressed
`digital data of the song; d) a song size field 39, contain(cid:173)
`ing the number of bytes in length of the compressed 55
`digital data; e) a graphics address field 41, containing
`the beginning address in the bulk storage unit 25 of the
`compressed digital data of a graphics image, if any, to
`be associated with the song; f) a graphics size field 43,
`containing the number of bytes in length of the com- 60
`pressed graphics image; and g) a play count field 45,
`containing a count which indicates the number of times
`this specific song has been played. By parsing the mas(cid:173)
`ter catalog 27, the host computer 21 can quickly locate
`all available information relating to any available song. 65
`The master catalog 27 also stores data particular to each
`jukebox such as the number of times each available song
`has been played, the coin intake for that jukebox, etc.
`
`4
`The data particular to each jukebox is uploaded from
`the jukebox to the central management system 11 to
`update the master catalog 27.
`Returning to FIG. 1, in order to add to the master
`5 library 23 and associated master catalog 27, the host
`computer 21 receives, has compressed and stores in the
`bulk storage unit 25 digital data representing the new
`song and associated pictorial graphics. The host com(cid:173)
`puter 21 receives the digital data for storage from three
`10 sources: 1) a compact disc read only memory
`(CDROM) reader 51, which reads CDROMs; 2) a
`graphics scanner 53, which digitizes pictorial graphic
`images; and 3) an analog to digital (A/D) reader/con(cid:173)
`verter 55, which reads analog data from both tapes and
`15 records and then converts the analog data into digital
`data. A compression circuit 52 using an adaptive-delta,
`pulse-code-modulation compression
`scheme com(cid:173)
`presses the digital data before it is stored. Other com-
`pression schemes may also be used. The compression
`circuit 52 might also be fully replaced by a software
`algorithm which is executed by the host computer 21.
`FIG. 3 more specifically illustrates the operation of
`the host computer 21 in adding new songs to the master
`library 23. At a block 61, the user is initially prompted
`by the host computer 21 to enter a new song title and
`category. The host computer 21 writes this information
`into the title field 31 and classification field 33 of a new
`song record 29 at a block 63. Next, at a block 65, the
`host computer 21 prompts the user to place either a
`CDR OM into the reader 51 or a record or tape into the
`reader/converter 55. After the user has completed this
`placement, at a block 67 the host computer 21 identifies
`available storage space in the bulk storage unit 25 by
`analyzing the space in use as described in the current list
`of song records 29 in the master catalog 23. The begin(cid:173)
`ning address of this available storage space is placed in
`the song address field 37 of the new song record 29.
`Thereafter, at a block 69, the host computer 21 provides
`a read enable signal on a bus 50 to either the reader 51
`or reader/converter 55. Either the reader 51 or reader/(cid:173)
`converter 55 responds by reading and sending digital
`data representing the new song to the host computer 21
`via the bus 50. Utilizing a bus 54, the host computer 21
`forwards the digital data received to the compression
`circuit 52, receives compressed digital data from the
`compression circuit 52 and writes the compressed digi-
`tal data into the bulk storage unit 25. At a block 71,
`upon reaching the end of the digital data output, i.e., the
`end of a song, the host computer 21 writes the byte
`length of the digital output into the song size field 39.
`The host computer 21 at a block 73 prompts the user
`to load a picture, such as an album cover, into the
`graphics scanner 53. At a block 75, the host computer
`21 identifies further available storage space in the bulk
`storage unit 25 and places the beginning address thereof
`into the graphics address field 41. Once a picture is
`loaded, the host computer 21 at block 77, using the bus
`50, provides a read enable signal to the scanner 53
`which responds via bus 50 by digitizing the picture and
`transferring the digitized output to the host computer
`21. At a block 79, using the bus 54, the host computer 21
`forwards the digitized data of the picture to the com(cid:173)
`pression circuit 52, receives compressed digitized data
`from the compression circuit 52, and writes the com(cid:173)
`pressed digitized data into the bulk storage unit 25. At a
`block 81, upon reaching the end of the digitized output,
`i.e., the end of the picture, the host computer 21 places
`the byte length of the digitized output into the graphics

`Returning to FIG. t, each computer jukebox t3 plays
`Thereafter, at a block tOS, by examining each play
`count field 4S in the copy ofthe catalog 9S received, the
`songs and displays graphics which are stored locally in
`the large-volume data storage unit 93. The storage unit 10 management system 11 determines the royalty amount
`due per song and whether to replace or update specific

`in the master library 27 maintained by the central man-
`song entries stored in the jukebox t3. The management

`box t3. The storage unit 93 also stores a catalog 9S that
`branches to a block t09 to terminate communication
`with the jukebox t3. If, however, replacements are

`management system 11 downloads to the jukebox t3 the
`transmission link tS. The jukebox t3 permits this moni-

`toring and updating at any time with no impact on its
`replacement song. In a corresponding block t43, the
`25 jukebox t3 replaces the song record 29 in the catalog
`end-user performance.
`The jukebox t3 also includes a processing circuit t2t
`9S. Thereafter, the jukebox t3 identifies available star-

`dress thereof into the song address field 37 in a corre-
`processor UtA operates in accordance with the soft- 30 sponding block t4S. Afterwards, at a block 113, the
`central management system 11 downloads the com-
