Next, with reference to Figure 4, functions that the personal computer 1 can perform executing predetermined programs will be described. Figure 4 is a block diagram of the functions of the personal computer 1, which can be performed by the central processing unit 11 executing the predetermined programs. The central processing unit 11 executes a content management program 111 consisting of several programs that include an EMD 131 selection program, an income / extraction management program 132, an encryption method conversion program 133, a compression method conversion program 134, an encryption program 135, a usage rule conversion program 136, a signature management program 137, an authentication program 138, a decryption program 139, a PD controller 140, and acquisition controllers 141 and 142. The content management program 111 has revolved instructions, encrypted instructions or the like, for example, to hide what has to be done with these instructions. That is, it is difficult to know what should be done according to the content management program 111. For example, even if the content management program 111 is read directly by some user, no instruction included in program 111 will be identifiable. When the content management program 111 is installed on the personal computer 1, the EMD 131 selection program will not be included in the content management program 111 but will be received through the EMD 3 server through the network 2 during EMD registration, which will be described in more detail later. The EMD 131 selection program is for selecting a connection with any of the EMD servers from 4-1 to 4-3 and makes an application program of purchases 115 or purchase controller 141 or 142 communicate with any of the EMD servers 4-1 through 4-3 (for example, downloading a content when purchasing a similar one). The income / extraction management program 132 must adjust either the revenue or the extraction, and extracted contents stored in content files 161-1 to 161-N to any of the portable devices 6-1 to 6-3 based on use rule files 162-1 to 162-N recorded in a content database 114 or enter contents stored in portable devices 6-1 to 6-3. Corresponding to any of the income or extraction adjustment above, the revenue / extractions management program 132 updates the usage rule data stored in usage rule files 162-1 to 162-N recorded in the database of content 114. The encryption method conversion program 133 ee to convert an encryption method that has been employed to encrypt a content that the purchase application program 115 has received from the EMD server 4-1 through the network 2 , a method that has been used to encrypt a content that the purchase controller 191 has received from the EMD server 4-2 through the network 2, or a method that has been used to encrypt a content that the purchase controller 142 to received from the EMD server 4-3 through network 2, to the same encryption method as the method that has been used to encrypt the contents stored in the content files 161-1 to 161-N that the content database 114 has registered there. Likewise, by transferring a content to the portable device 6-1 or 6-3, the encryption method conversion program 133 is used to convert an encryption method of a content to be extracted into a method in the portable device 6- 1 or 6-3. The compression method conversion program 134 is for converting a compression method that has been employed to compress a content that the purchase application program 115 has received from the EMD server 4-1 through the network 2, a method that has been integrated to compress a content that the purchase controller 141 has received from the EMD server 4-2 through the network 2 or a method that has been used to compress a content that the purchase controller 142 has received from the EMD server 4-3 through network 2, to the same compression method that has been employed to compress content stored in the 161-1 to 161-N content files and the 114 database has been recorded. Likewise, when a content is extracted to the portable device 6-1 or 6-3, the method conversion program of compression 134 is used to convert the compression method that has been employed for the purpose of compressing the tablet to be reviewed to a method that portable device 6-1 or 6-3 can employ. The encryption program 135 is for encrypting a content that has been read from a CD, for example, and supplied from a registration program 113 (not yet encrypted) by the encryption method that has been used to encrypt contents stored in the content files 161-1 to 161-N registered in the content database 114. The usage rule conversion program 136 is to convert the usage rule data for content that the purchase application program 115, the purchase control 141 or the purchase controller 142, has received from the EMD server 4-1, or 4-2, respectively, through network 2, in the same format as the format of the rule formats. use stored in the 161-1 to 161-N usage rule files registered in the content database 114. Likewise, when a content is extracted to the portable device 6-1 or 6-3, the conversion program Use rule 136 converts the usage rule for the content to extract in the usage rule data that the portable device 6-1 or 6-3 can use. The signature administration program 137, is to find, before entry or extraction, a contain any use-rule forgery based on the signature (to be described in more detail below) included in the usage rule data stored in the files in use rule files 162-1 to 162-N recorded in the content database 114, and updates the signature included in the usage rule data correspondingly to an update of the usage rule data stored in the usage rules files 162-1 to 162-N registered in the base of content data 114, the update occurred after the entry or extraction of the content. The authentication program 138 is to provide mutual authentication between the content management program 111 and the purchasing application program 115 and a mutual authentication in the content management program 111 and the purchase controller 141. Likewise, the program authentication 138 stores authentic keys for use in mutual authentication between the EMD server 4-1 and the purchase application program 115, a mutual authentication between the EMD server 4-1 and the purchase controller 141, and a mutual authentication between the EMD server 4-3 and the purchase controller 142. The authentication key used by the authentication program 138 for mutual authentication has not yet been stored in the authentication program 138 when the Administration program 111 is installed on the personal computer 1 but will be supplied to the EMD 3 registration server and stored in the authentication program 138 when by registration it has been effected successfully by a program of display of several operation / instructions 112 When the personal computer 1 reproduces contents stored in the contents files 161-1 to 161-N registered in the content database 114, the decryption program 139 is for deciphering the content. When a predetermined content is extracted to the portable device 6-2 or when a predetermined content is input from the portable device 6-2, the PD 140 controller must supply the portable device 6-2 with the content or a command for that the portable device 6-2 executes a predetermined operation. When a content is extracted from a predetermined content towards the portable device 6-1 or when a predetermined content is input from the portable device 6-1, the PD 140 controller must supply to a device driver 116-1 the content or a command for the device driver 116-1 to execute a predetermined operation. When a predetermined content is extracted to the portable device 6-3 or when a predetermined content from the portable device 6-3, the PD 140 controller must supply a device driver 116-2 with content or a command for the device driver 116-2 to perform a predetermined operation. The acquisition controller 141 is what is known as a plug-in program. It is installed together with the content management program 111, and is supplied from the EMD 3 registration server through the network 2 or in accordance with what is registered in the predetermined CD. Installed on the personal computer 1, the purchase controller 141 must send data to the content management program 111 and receive data from the content management program 111 through an interface of a predetermined type that has the content management program 111 The purchase controller 141 sends to the EMD server 4-2 through network 2 a request to send a predetermined content and receives the content from the EMD server 4-2. Likewise, the purchasing controller 141 makes an account when it receives content from the EMD server 4-2. The purchase controller 142 is a program that must be installed in conjunction with the content management program 111. A request for sending predetermined content must be sent to the EMD server 4-3 via network 2 and receives content from EMD server 4-3. Also, the purchase controller 142 makes an account when it receives content from the EMD server 4-3. The display program / operation instruction 112 should cause the display unit 20 to display a predetermined window image based on a filtering data file 181, display a data file 182, image files 173-1 to 183- K or story data file 184, and instructs content management program 111 through keyboard 18 or mouse 19 to enter or extract content. The filtering data file 181 has there stored data to weigh each of the contents stored in the content files 161-1 to 161-N recorded in the content database 114, and is recorded in the hard disk drive 21. The display data file 182 has stored there data corresponding to the contents stored in the contents files 161-1 to 161-N recorded in the content database 114, and is recorded in the hard disk drive. 21 The image files 183-1 to 183-K have images stored there corresponding to the contents files 161-1 to 161-N registered in the content database 114 or images corresponding to packets that will be described with further details, and recorded on the hard drive 21. Next, the image files 183-1 to 183-K will be known simply as "image files 183" when it is not necessary to identify them individually. The story data files 184 have stored history data therein including numbers of times that the contents stored in the content files 161-1 to 161-N recorded in the content database 114, have been extracted, the number of times that the contents stored in the contents files 161-1 to 161-N have been entered, the dates of the income and extractions, etc., and is recorded in the hard disk drive 21. For the record, the operation display / instructing program 112 must send a previously stored ID of the content management program 111 to the EMD 3 registration server through the network 2 while receiving an authentication key and program to EMD selection 131 from the EMD registration service 3, and supplies the content management program 111 with the authentication key and selection program EMD 131. The registration program 113 must extract data, eg registration time from data, etc., from CD which is the optical disc 42 placed in the unit 22 based on a operation performed through the keyboard 18 or mouse 19, while displaying a predetermined window image. The registration program 113 requests, through network 2, the sending to the server WWW 5-1 or 5-2 data corresponding to a CD (for example, album name, artist name, and cities) or data which correspond to contents recorded on a CD (for example, content names and the like) based on the time of recording content recorded on CD while receiving from the WWW server 5-1 or 5-2 data corresponding to a CD data that correspond to content recorded on CD. The registration program 113 must supply the received data corresponding to a CD or data corresponding to the contents recorded on the CD to the display program / operation instruction 112. When it is supplied with an instruction, registration, the registration program 113 of contents of a CD which is the optical disk 42 placed in the unit 22 and sends it to the content management program 111. The content database 114 stores in any of the content files 161-1 to 161-N contents supplied from the administration program 111, compressed by the predetermined method and encrypted by the predetermined method (i.e., they are recorded on the hard disk drive 21). The database 114 stores in any of the usage rule files 162-1 to 162-N corresponding to the content files 161-1 to 161-N, respectively, which have contents stored there use rule data corresponding to the contents stored in the content files 161-1 to 161-N, respectively (ie, they are recorded on the hard disk drive 21). The content database 114 may have either the 161-1 to 161-N content files or 162-1 to 162-N usage rule files stored therein as registers. For example, usage rule data that corresponds to a content stored in the 161-1 content file is stored in the usage rule file 162-1. Likewise, usage rule data corresponding to a content stored in the 161-N content file are stored in the 162-N usage file. The content files 161-1 to 161-N will then be known simply as 'content file 161' when they are not individually required to be identified, as well as the rule files for use 162-1 to 162- N will be known simply as 'use rule files 162' when it is not necessary to identify them individually. The personal computer 1-2 has a structure similar to the structure of the personal computer 1-1, the explanation is omitted. With reference to one of FIGS. 5, an example of usage rule data stored in the rule files is shown. of use 162-1 to 162-N. For the element 'Content ID', there is data set to identify a content stored in each of the content files 161-1 to 161-N For the element 'Possible extraction?', Either 'YES' is set NO. "When set to" YES "for this item, the content management program 111 can extract content identified with the" Content ID "to any of the portable devices 6-1 to 6-3 when" NO "is set. for the element 'Possible extraction?', the content management program 111 will not extract the content identified with 'Content ID' to any of the portable devices 6-1 to 6-3. For the element 'Number of possible extractions ", there is a set number of times that the content management program 111 can perform a content extraction. When the content management program 111 extracts a content at a time, the number for the element 'Number of possible extractions' is correspondingly decreased.When the content management program 111 enters a content once, the number for the element 'Number of possible extractions' is increased correspondingly. When the number for the element 'Number of extractions possible' changes from '1"to O" result of extractions made by the content management program 111, 'NO' is set for the element 'Possible extraction?' . When the number for the element 'Number of possible extractions' changes from O "to '1" as a result of making an entry for the content management program 111,' YES 'is set for the element' Extraction possible? "In the element 'Possible Movement?', There is either 'YES' or 'NO'. when 'YES' is set for this element, the content management program 111 may move a content identified with the 'Content ID'. When a 'NO' is set for the 'Possible Movement' element, the content management program 111 will not displace the content identified with the 'Content ID.' In the 'Possible copy?' Element, either 'YES " or not". When 'YES' is set for this item, the content management program 111 can copy content identified with the 'Content ID'. When 'NO' is set for this item, the content management program 111 will not copy content identified with the 'Content ID'. In the item 'Number of Possible Copies', a number of times that the content management program 111 can perform the content copy is set.In the 'Period of Use' element, a period is set during which a content identified with the 'Content ID' can be used (extraction or reproduction). At the time 'district usable for content', a district is established (for example, Japan or the world) where a content identified with The 'Content ID' can be used (extracted or reproduced) In the 'Signature' element, data (known as 'signature data') that generates the signature management program 137, based on data set in the elements 'Content ID' to 'District usable for the content.' The signature data is used to detect any falsification of usage rule data The algorithm employed by the signature management program 137 to generate the Signature data is a one-way function, since it is not disclosed to the public, it is difficult for any other person who was not the provider of the content management program 111 to generate data from correct signatures based on data set in the elements 'Content ID' to 'District usable for content'. The acquisition application program 115 is supplied from the EMD registration server 3 through the network 2 or in accordance with the predetermined CD register. The acquisition application program 115 is to request the EMD server 4-1 to send a predetermined content, it receives the contents of the EMD server 4-1 and supplies it to the content management program 111. Likewise, the procurement application program 115 performs an accounting when it receives the contents of the EMD server 4-1. Next, the correspondence between the data stored in the display data file 82 and the content files 161-1 to 161-N stored in the content database will be described: A content stored in any of the content files 161 -1 to 161-N belongs to a default package. With details, the package is an original package, the distribution package or a filtering package. More than a content belongs to the package to the original. The original package corresponds to the content classification in EMD servers 4-1 to 4-3 (for example, what is known as an album) or to a CD. The contents belong to any original package and can not belong to several original packages. The original package to which the contents belong can not be modified. The user can edit (add information or modify aggregate information) a part of the information that corresponds to the original package. With reference to Figure 6, an example of the relationship between the original package display data is shown 201 included in a display data file 182 and content files 161-1 to 161-N. The relationship will define the relationship between an original package and contents. The original package display data 201 includes packet display data 221-1 through 221-M. The display data of pack 221-1 is related to the content display data 221-1-1 to 221-1-1. The display data of the 221-1-1 package corresponds to a content stored in the contents file 161-1. The usage rules data for a content stored in the content file 161-1 are stored in usage rule 162-1. The content display data 221-1-2 corresponding to a content stored in the contents file 161-2. The usage rule data for a content stored in the content file 161-2 is stored in the use rule 161-2. The content display data 221-1-i corresponds to a content stored in the 161-q content file. The usage rule data to a content stored in the 161-q content file is stored in the usage rule 162-q. The packet display data 211-2 relates to the content display data 221-2-1 to 221-2-j. The content display data 221-2-1 corresponds to a content stored in the content file 161- (q + 1).

The usage rule data for a content stored in the content file 161- (q + 1). It is stored in the rule of use 162- (q + 1). The content display data 221-2-2 corresponds to a content stored in the content file 161- (q + 2). The usage rule data for a content stored in the content file 161- (q + 2) is stored in the usage rule 162- (q + 2). The content display data 221-2-j corresponds to a content stored in the 161-r content file. The usage rule data for a content stored in the 161-r content file is stored in the 162-r usage rule. Similarly, packet display data 211-M relates to content display data 221-M-1 through 221-M-p. The content display data 221-M-p corresponds to a content stored in the 161-N content file. The usage rule data for a content stored in the 161-N content file is stored in the usage rule 162-N. Next, the packet display data 211-1 to 211-M will be known simply as "packet display data 211" when it is not necessary to identify them individually, as well as the content display data 221-1- to 221. -Mp will be known simply as "content display data 221" when it is not necessary to identify them individually.Similarly, display and content data 161-1 to 161-N will be known simply as "content display data 161" when it is not necessary to identify them individually. The files of the usage rule 162-1 to 162-N will be known simply as "usage rule file 162" when it is not necessary to identify it individually. With reference to one of FIGS. 7A to 7C, an example of the composition of the display data file 182. Figure 7A shows an example of the packet display data 211. The packet display data 211 includes packet ID data to identify a packet, package type data to identify already either a My Selection package or filtering packet, package name data, artist name data, gender name data, content ID data indicating name of the image file where an image corresponding to a package is stored, as well as content ID data that correspond to more than a content belonging to a package.The information that corresponds to an original package added by the user is added to the packet display data 211. Figure 7B is an example of the display data of content 221. The content display data 221 includes content ID data, original packet ID data for the identification of an original packet to which a corresponding packet belongs, content name data, data as to the number of extractions , and data to indicate the name of an image file where an image corresponding to a content is stored. In addition, the display data file 182 may be constructed in such a manner as to correspond to a content ID and in such a manner that it has data type and data recorded therein, as shown in Figure 7C. The My Selection package has more than one content freely selected by the user. The user can freely make an edition in such a way that it has content that belongs to a My Selection package. A content may belong to more than one My Selection package, and may not belong to any My Selection package. Referring now to Figure 8, there is shown an example of a relationship between the My Selection package display data 241 pertaining to the display data file 182 and the 161-1 to 161-N content files. The relationship defines the relationship between a My selection and contents package. My Selection package display data 241 includes packet display data 251-l to 251-S.

The packet display data 251-1 is related to the content display data 221-1, 221-2-2 or 221-1-i corresponding to a setting set by the user. The package display data 251-2 is related to the content display data 221-2- j, 221-3-1 or 221-1-2 corresponding to a setting made by the user. Similarly, the packet display data 251-S is related to the content display data 221-2-2 or 221-1-i corresponding to a setting set by the user. Next, the packet display data 251-1 to 251-S will be known simply as "packet display data 251" when it is not necessary to identify them individually, since the packet display data 251 has a similar composition. to the composition of the packet display data 221 that has been previously described to Figure 7A, it will not be described further.Thus, the user can have a desired content belonging to a My Selection packet.A content belongs to several My Selection packages as the case may be, the filtration packet has a selected content based on filtering data stored in the filtering data file 181. The filtering data is supplied from the EMD servers 4-1 to 4-3 or WWW server 5-1 or 5-2 through network 2, or as registered on a predetermined CD. The user can edit filtering data stored in the filtering file 181. The filtering data is a reference for selecting a predetermined content or calculating a weight corresponding to a content. For example, using the filtering data corresponding to J-POP (Japanese pops) of the week, the personal computer 1 can identify 10 contents from the best place to the tenth place of the week. The filtering data file 181 includes, for example, filtering data for selecting the content in the descending order of the periods during which they were extracted in the last month, filtering data for selecting contents that have been frequently extracted during the last half. year or filtering data to select content that includes the word 'love' (love) in its name Thus, a content in the filtering package is selected by relating the content display data 221 that correspond to the content (including established data by the user in the content display data 221) or history data 184 with a filtering data With reference now to Figure 9, there is shown an example of the relationship between the display data of the filtering 281 belonging to the display data file 182 and content files 161-1 to 161-N. The relationship defines the relationship between a My Selection package and contents. The filtering display data 281 includes packet display data 291-1 through 291-A. The package display data 291-1 is related to the content display data 221-2-1, 221-1-2 or 221-M-p. The package display data 291-2 is related to the content display data 221-1-i, 221-2-j and 221-2-2. Similarly, packet display data 291-A is related to content display data 221-1-i, 221-2-j and 221-2-2. Next, packet display data 291-1 through 291-A will be known simply as "packet display data 291" when it is not necessary to identify them individually, since packet display data 291 has a similar composition. of the packet display data 221 which has been previously described with reference to Figure 7A, will not be described further.So, a predetermined content selected by the user operating the personal computer 1 belongs to a filtering packet and a content belongs to to several filtration packages as the case may be. reference to Figure 10. When the display program / operation instruction 112 is initially started with the content management program 111 and display program / operation instruction 112 installed on the personal computer 1, it references a resource locator uniform (URL) and the like previously stored there, and connects to the EMD 3 registration server through the network 2. The EMD 3 registration server sends data for display of a screen intended for registration to the display / instruction program of operation 112. The display program / operation instruction 112 will display a screen having an EMD registration button 311 placed therein in the display unit 20 as shown in Figure 11 for example. When the MD 311 registration button is selected with the mouse, e 1 display program / operation instruction 112 requests the EMD registration server 3 to send an authentication key 301 and a previously registered EMD 131 selection program on the? MD 3 registration server together with a pre-stored ID for the content management program 111 and data necessary for registration (eg, personal computer user's name 1 and credit number). When it is determined that the ID received for the program content management 111 is valid, the EMD registration server 3 sends the authentication key 301 and the EMD selection program 131 to the display program / operation instruction 112 through the network 2. On the contrary, when it is determined that the received ID for the content management program 112 is not valid, the registration server EMD 3 sends a predetermined error message to the display program / operations instruction 102 through the network 2. When the ID for the program of content management 111 is not valid, the display program / operation instruction 112 can not acquire an authentication key 301 and EMD selection program 131. Upon receipt of an authentication key 301 and the selection program of EMD 131 from of the EMD registration server 3, the display / operation instruction program 112 supplies an authentication key 301 and the program selection of EMD 131 to the content management program 111. When it receives the authentication key 301 and the EMD selection program 131 from the display program / operation instruction 112, the content management program 111 installs and starts the program. selection of EMD 131, and provides the key to authentication 301 to the authentication program 138. The authentication program 138 stores there the acquired authentication key 301. After startup, the EMD selection program 131 displays on the display unit 20, a window where buttons are found to start the connection with any of the EMD servers 4-1 through 4-3 as shown in Figure 12 for example. When an EXA-SOFT AUDIO 331 button is selected with the mouse for example, the content management program 111 starts an acquisition application 151 and connects the acquisition application 151 to the EMD server 4-1. At this time, the authentication program 138 employs the authentication key 301 to execute mutual authentication with the acquisition application 151 and causes the acquisition application 151 to perform mutual authentication with the EMD server 4-1. When the acquisition application 151 has successfully performed mutual authentication with the EMD server 4-1, it displays, in the display unit 20, a screen for acquiring a content as shown in Figure 13, for example. When a SOLID AUDIO 332 button is selected with the mouse, for example, as shown in Figure 12, the content management program 111 installs the acquisition controller 141 that a program, and connects the acquisition controller 141 to the EMD server 4-2. At that time, the authentication program 138 employs the authentication key 301 to execute mutual authentication with the management controller 141 and causes the acquisition controller 141 to perform mutual authentication with the EMD server 4-2. When the acquisition controller 141 has successfully performed mutual authentication with the EMD server 4-2, it displays on the display unit 20, a screen for acquiring a content as shown in Figure 14, for example. Similarly, when a button 333 is selected through the mouse for example, as shown in Figure 12, the content management program 111 connects the acquisition controller 142 to the EMD server 4-3. At this time, the authentication program 138 employs the authentication key 301 to execute mutual authentication with the EMD server 4-3 through the acquisition controller 142. Note that when a check button 334 (DIRECT CHECKOUT) (REMOVAL) DIRECT) Shown in Figure 12 is selected, a content received from any of the EMD servers 4-1 to 4-3 (ie, the content is acquired) is stored in the content database 114 and is drawn to any predetermined portable device selected among portable devices 6-1 to 6-3. Next, the reading of a content from a CD placed in the unit 22 and the recording of the content will be described. Referring now to Figure 15, there is shown an example of the display window / operation instruction that the display program / operation instruction 112 displays in the display unit 20 when the EMD registration starts thereafter. The display window / operation instruction has a button 341 for starting the registration program 113, a button 342 for starting the EMD selection program 131, a button 341 for displaying a field in which entry or extraction is selected, and a button 344 to display a field for the edition of a My Selection package, that is, the display data of My Selection 241 package. When a button 345 is selected, data corresponding to an original package is displayed in a field 351. When a button 346 is selected, data corresponding to a My Selection package are displayed in field 351. When a button 347 is selected, data corresponding to a filtering packet is displayed in data 351. The data displayed in field 351 is related yet package, and it is, for example, a package name or artist name. As shown in Figure 15, field 351 shows, for example, a package name 'FIRST' (FIRST) and artist name 'A TARO' stored in the package display data 221-1, a name of package 'SECOND' (SECOND) and an artist name 'A. TARO' stored in the package display data 221-1, etc. In a field 351, data corresponding to the contents belonging to selected packets in field 351 are displayed. Data displayed in this field 352 includes content name, playing time or number of possible extractions, etc., for example. In Figure 15, for example, since a packet corresponding to packet display data 221-2 is selected, a content name of "MINAMI-NO-SAKABA" and a number of possible ones are displayed in field 351. extractions' .. '(indicating three extractions) stored in the content display data 221-1 corresponding to contents belonging to a packet corresponding to the package display data 221-2, a content name' KITA- NO-HAKABA "and the number of possible extractions * .." (indicating two extractions) stored in the content display data 221-2, etc. Note that the number of possible extractions may not only be indicated with a number of predetermined forms (for example, star, moon as similar) as shown in Figure 15, but may also be represented by a number or a note or several notes (a note of a sixteenth for an extraction, two notes of a sixteenth or a note of an eighth for two extractions, three notes of a sixteenth or an eighth note with a dot for three extractions, etc.). Likewise, the display window / operation instruction has there placed a field 348 where an image or the like corresponding to a selected packet or content is displayed, and a button 349 for use for the reproduction of a selected content (output of sound corresponding to the contents of the horn 24). To play the selected content, the button 349 must be selected. By selecting a predetermined content name displayed in a field 352 and deleting an operation while displaying data corresponding to the original package displayed in field 351 with the button 345 activated, the display program / operation instruction 112 will cause the content management program 111 to erase a predetermined content stored in the content database 114 and corresponding to the selected content name. Referring now to Figure 16, there is shown, for explanation, a window that the registration program 113 displays or the display unit 20 when encompassed by selecting the button 341 with the mouse. The registration program 113 reads a playing time of a content from a CD placed in the unit 22, and displays it in a field 383. Since the name of the content is unknown, the registration program 113 will present 'UNKNOWN' (unknown) in a part of field 383 where a content name should be displayed Since both the title of a CD placed in unit 22 and the artist's name are unknown, registration program 113 will display 'UNKNOWN' (unknown ) in each of a field 381 where a CD title should be displayed and in a field 382 where an artist name should be displayed. The window displayed on the display unit 20 by the registration program 113 further has a button 384 that must be selected for the acquisition of information from a CD, and a button 385 for determining whether or not a content read from the CD must be automatically extracted to any of the portable devices 6- 1 to 6-3 when the content read is recorded in the content database 114. When the button 385, for example, is selected, the registration program 113 will cause the display unit 20 to display a selection menu showing the list of portable devices 6-1 to 6-3. When the user selects any of the portable devices 6-1 to 6-3 from the selection menu, the personal computer 1 will automatically extract a content registered from the CD to any of the portable devices 6-1 to 6-3. When the user selects 'NO CHECKOUT' from the selection menu, the personal computer 1 will not extract any content registered from the CD The window that the registration program 113 causes the display unit 20 to display also has placed there a button 386 for instructions as to the start of registration of a content registered on the CD With reference now to Figure 17, a property dialog box is displayed which the registration program 113 displays by the display unit 20 when it is necessary to acquire CD information from any of the WWW servers 5-1 and 5-2, and where it is selected from which of the WWW servers 5-1 to 5-2 the CD information must be acquired The property dialog box has connected there data 401 where it is selected from which of the WWW servers 5-1 and 5-2 the CD information must be acquired. When 'CDDB' for example is set in field 401, the registration box 113 will request that the WWW server 5-1 send the CD information when 'CDNEW JAPAN' is set. (for example, the name of a company or site that provides a service similar to 1 provided by CD NEW (trademark)) is set in field 401, registration program 113 will request that the WWW server 5-2 corresponding to CDDB send the CD information. When set to 'CDDB' is set in field 401, fields 402 and 403 will be ready for that adjustment URL in the first CDDB site should be set in field 402 while in the second CDDB site should be set in the field 403. When the CD information is received from any of the WWW servers 5-1 and 5-2, a directory in which the received information must be registered is established in a field 404 (any directory of the display unit 21). When a button 405 that is also in the property dialog box is selected through the mouse, the registration program 113 will have access, through network 2, to a predetermined server of the WWW servers based on URL previously stored in the registration program 113, will acquire information as soon as URL in the first CDDB site and URL in the second CDDB site and will establish the URL information in the first CDDB site as candidate information to be placed in field 402 while placing the URL information in the second CDDB site as candidate information to be placed in field 403, as shown in Figure 18. When button 384 shown in Figure 16 is selected after the user has established 'CDDB' in field 401, URL in the second CDDB site in field 402 and URL in second CDDB site in field 403 as shown in Figure 19, registration program 113 will connect to server 5-1 of WWW based on URL set in field 402 and URL will be set in field 403, it will request from WWW server 5-1 CD information following a procedure corresponding to 'CDDB' established in field 401, and it will receive CD information from server 5-1 of WWW . Referring now to Figure 20 a window is shown that the registration program 113 causes the display unit 20 to display when it has received the CD information from the WWW server 5-1 with the selection of the button 384. Based on the CD information received from the WWW server 5-1, the registration program 113 will display a CD title such as "synchronized" in field 381, and also an artist name such as "KUWAI" in the field 382. Based on the CD information received from the WWW server 5-1, the registration program 113 will display content names such as 'HIT', 'PLANET', 'BLACK', 'SOUL', etc. For example, in a part of field 383 where a content name must be displayed, and also an artist name, for example, 'KUWAI', for example in a part of field 383 where a name of When you have received more than two CD information from the WWW server 5-1, the registration program 113 will cause the display unit 20 to display a dialog box as shown in Figure 21 for selection by the user. Any of the CD information Figure 22 shows a dialog box that the registration program 113 causes the display unit 20 to display when the button 384 is selected with 'CDNEW JAPAN' set in field 401 and in which set a search key As shown in Figure 22, the dialog box has buttons 431, 432, 433, and 434 there. The button 431 must be activated by selecting with the mouse to search CD information by taking an album name as a search key. The search key for the album name is set in a field 441 also placed in the box dialogue. The button 432 must be activated by selecting the mouse CD information search by taking an artist name as a search keyword. The search key for the artist name is set in a field 442 also placed in the dialog box. The button 433 must be activated by selecting CD information search by taking a content name as the search keyword. The search key for the content name is set in a field 443 also placed in the dialog box. Button 434 must be activated by selecting CD information search by taking the product number as the search keyword. The search keyword for the product number is set in a field 444 also placed in the dialog box. To search CD information, at least one of buttons 431 to 434 is activated. When CD information is searched by taking an artist name as a search keyword as shown in Figure 23, button 434 is activated, and set a string of characters in field 442 that indicate the name of the artist, such as "KUWAI." When the search button placed in the dialog box to set a search keyword is selected, the registration program 113 will connect to the server 5-2 of WWW based on a previously stored URL or similar, it will request to the server 5-2 of WWW CD information following a procedure corresponding to 'CDNEW JAPAN "established in field 401 and based on the search keyword set in the dialog box and you will receive the CD information from the WWW server 5-2.The WWW server 5-2 will send the CD information along with data to view an image which will prompt the user to acquire a CD related to the searched CD information to the personal computer 1 as shown in Figure 24. The user of the personal computer 1 can acquire a predetermined CD through the network 2 based on the data to display the image that prompts the user to acquire the CD With reference now to Figure 25, there is shown, for example, a window that the registration program 113 makes the display unit 20 visua Check when you have received the CD information from WWW server 5-2 after selecting the search button 384 placed in the dialog box to set the search keyword. Based on the CD information received from the WWW server 5-2, the registration program 113 displays a CD title such as "synchronized", for example, in field 381, and also an artist name, for example 'KUWAI' in field 382. Based on the CD information received from WWW server 5-2, registration program 113 will display content names such as 'HIT', 'PLANET', 'BLACK', 'SOIL' , etc., for example in a part of field 383 where a content name must be displayed, and also an artist name, for example, 'KUWAI' for example in a part of field 383 where it should be displayed an artist's name After the registration program 113 has received a predetermined CD information, it will store the CD information in the directory on the hard disk drive 21, designated in field 404. When it receives instructions to acquire CD information by the fact that the user selects the button 384 with the mouse or similarly, the registration program 113 first searches for the directory on the hard disk drive 21, designated in the field 404. When the CD information is stored in the directory in a unit of hard disk 21, designated in field 404, registration program 113 displays a dialog box 461 illustrated in Figure 26 to prompt the user to select whether to use the CD information stored in the directory designated in field 404 When button 386 for instruction for registration starts of any of the contents displayed in the window that the registration program 113 causes the display unit 20 to display is selected through the mouse, the registration program 113 reads the contents from a CD placed in the unit 22 and supplies the content read from the CD together with the CD information to the content management program 111. The compression method conversion program 134 in the content management program 111 compresses the content supplied from the registration program 113 to through a predetermined compression method, and the encryption program 135 encrypts the compressed content. The usage rule conversion program 136 generates usage rule data corresponding to the compressed and encrypted content. The content management program 111 thus supplies the compressed and encrypted content together with the usage rule data to the content database 114. The content database 114 generates the content file 161 and the file of the content. use rule 162 corresponding to the content received from the content management program 111, and store the content in the content file 161 and the usage rule data in the usage rule file 162. When the content and data of rule of use that correspond to the content are stored in the base of content data 114, the content management program 111 supplies the CD information and usage rule data received from the registration program 113 to the display program 112 / operation instruction. The display program / operation instruction 112 generates the original package display data 201 and content display data 221 based on the CD usage and information rule data corresponding to the content stored in the content database 114 for the record. As shown in Figure 27, when the engine 345 is selected, the name of the original package (CD title) corresponding to the content stored in the database 114 by the record is displayed in field 351 in the display window /operation instruction. When the package is selected, a content name corresponding to the content read from the CD is displayed in field 352. When the content read from the CD is recorded in the content database 114 and when the button 385 is selected in the window that the registration program 113 causes the display unit 20 to be displayed (when said button is activated), the display program / operation instruction 112 displays in the display window / operation instruction, a field 481 in which to visualize, as shown in Figure 28, the name of a content stored in a previously designated portable device selected from portable devices 6-1 to 6-3. The display program / operation instruction 112 causes the content management program 111 to extract the content read from the CD and registered in the content database 114 to any of the portable devices 6-1 to 6-3, previously designated . Thus, only by keeping the button 385 activated in the window that the registration program 113 causes the display unit 20 to display, when the content of the read from the CD is recorded in the content database 114, the personal computer 1 it can extract the content read from the CD to any of the portable devices 6-1 to 6-3, previously designated. When the display program / operations instruction 112 has displayed field 431 in the display window / operation instruction, it also displays, in the display window / operation instruction, a field 482 where the name of a package is displayed portable to which a content stored in any of the portable devices 6-1 to 6-3, previously designated (ie, a packet to which a content stored in any of the portable devices 6-1 to 6-3 belongs) belongs, a button 483 for closing the field 481 and a button 484 for executing ingress or extraction.

Further, when the display program / operation instruction 112 has displayed field 481 in the display window / operation instruction, it displays, in the display window / operation instruction, also a button 491 to extract a content corresponding to a content name selected in field 352, a button 492 to set the entry of a content corresponding to a content name selected in field 481, a button 493 to set the entry of all contents corresponding to content names displayed in field 481 and a button 494 to cancel the entry or extraction establishment. Next, the establishment of income or extraction and execution of said income or extraction will be described. When the button 343 for displaying a file in which an entry or extraction is to be made is selected with the mouse, the display program / operation instruction 112 displays, in the display window / operation instruction, the field 481 in where the name of a content stored in any of the portable devices 6-1 to 6-3, previously designated, must be displayed. For example, when content names 'MIAMI-NO-SAKABA', 'KOTA-NO-HAKABA' and 'SHICHINARABE' displayed in field 352 are selected as shown in Figure 29 and when the button 491 is selected with the mouse, the display program / operation instruction 112 establishes the extraction of contents corresponding to the content names' MINAMI-NO-SAKABA ", 'KITA-NO-HAKABA' and 'SHICHINARABE' , respectively, and display the content names 'MINAMI-NO-SAKABA,' 'KITA-NO-HAKABA' and 'SHICHINARABE' in field 481, as shown in Figure 30. At this time, the visualization program / operation instruction 112 changes a number of possible extractions' ... " (which indicates three extractions) for the content name 'MINAMI-NO-SAKABA ", in field 352, a' .." (which indicates two extractions), a number of possible extractions '.. "for the content name' KITA-NO-HAKABA", also in field 352, a '. "(which indicates a single extraction), and a number of possible extractions' ..", for the content name 'SHICHINARABE "and also in field 352, a' ..", and displays the changed numbers of possible extractions in field 352. For example, when it is in the state shown in Figure 30, the content name 'KITA-NO-HAKABA' is selected in field 481 and button 492 is selected through the mouse, the program 112 of visualization / instruction of operations establishes the entrance of the content that corresponds to the name of content 'KITA- NO-HAKABA "and delete this content name from field 481, as shown in Figure 31. At this time, the display program / operation instruction 112 changes the number of possible extractions for the content name 'KITA-NO -HAKABA "". " (which indicates an extraction) displayed in field 352 to '.. "(which indicates two extractions), and displays the changed number of possible extractions, by dragging and leaving a package name displayed in field 351 to field 481 is set to extraction of all contents belonging to the packet corresponding to the packet name left and dragged in. With entry or extraction set only through the operation of buttons 491 through 494, the personal computer 1 does not execute any input or extraction.When the button 484 is selected via the mouse after the establishment of ingress or extraction through the operation of the buttons 491 to 494, the display / operation instruction program will cause the content management program 111 executes the registration or extraction, that is, when the button 484 is selected through the mouse, the program of display / operation instruction 112 will cause the content management program 111 to send either content to any of the portable batteries 6-1 to 6-3, or a predetermined command corresponding to input (for example, a command to erase a predetermined content stored in any of the portable devices 6-1 to 6-3), based on the input or extraction settings, and erasure usage rule data stored in the usage rule file 162 that corresponds to the content or command sent. When the entry or extraction is effected, the display program / operation instruction 112 updates a history data in the history data file corresponding to the content or command sent. The history data includes information to identify the content or data entered or extracted in which the content has been entered or extracted, and the name of any of the portable devices 6-1 to 6-3 to which the content has been extracted. Since the income extraction can be established in a short period of time, the user can quickly know the status after the execution of the input or extraction. Thus, the number of income or withdrawals that is made can be reduced to shorten the overall time necessary for income or extraction (including the time to establish and execute the income or extraction). Next, the edition of the My package will be described Selection, for example, adding a desired content or a My Selection preset. As shown in Figure 32, when the button 344 is selected to display a field in which a My Selection package is edited, the display program / operation instruction 112 displays, in the display window / operation instruction, a field 501 in which a content name must be indicated that corresponds to a content belonging to a My Default Selection package. At this time, the display program / operation instruction 112 is displayed, in the display window / operation instruction, a field 502 in which a selected My Selection package (stored in the package display data) should be displayed. 251-1 to 251-S). When the name of a My Selection to edit package is placed in field 502, the display program / operation instruction 112 displays, in field 501, a content name corresponding to the My Selection field that has the package name ( stored in a content display data 221 related to any of the packet display data 252-1 to 252-S). In addition, when the display program / operation instruction displays the field 101 in the window display / operation instruction, displays, in the display window / operation instruction, a button 521 for an operation so that it has a content corresponding to a content name selected in field 352 with content to a My Selection package whose name is displayed in field 502 (can store a content ID of the selected content display data 221 in any of the packet display data 251-1 to 251-S), a button 522 for an operation to erase the content that corresponds to the content name selected in field 501 from the My Selection package whose name is displayed in field 502 (to clear the content ID of the selected content display data 221 from any of the package display data 251-1 to 251-S), and a button 523 for an operation to cancel a previous operation (so that the content also belongs to the paq My Selection or to delete the contents of the My Selection package). For example, by displaying field 501 in the display window / operation instruction the user can make a package name 'My Best 1' be displayed in field 502, a content named 'North Star', a named content 'Shooting Star', a content named 'Multimillionaire' and a content named 'Slotl'.

That is, in response to a predetermined operation, the display program / operation instruction 112 stores in the package display data 251 where the package name 'My Best 1' is stored, the Ids for the content named 'North' Star ", the content called 'Shooting Star', and the content called 'South-Alpe', the content 'Multimillionaire', and the content named 'Slot 1', respectively. Likewise, when the package name displayed in field 351 is dragged and left in field 501, all the contents belonging to a packet corresponding to the packet dragged and left can belong to the My Selection packet whose name is displayed in the field 502. When the button 346 displayed in the display window / operation instruction to display, in field 351, data corresponding to the My Selection packet is activated, the display program / operation instruction 112 will display, in field 351, package names that correspond to the My Selection package (for example 'My Best 1', 'My Best 2', 'Snow Drive', 'MINAMI-NO-SHIMA-Select', 'Traveling Abroad', etc.) and in the field 352 names of contents that belong to a My Selection package that corresponds to a selected package name, as shown in Figure 33. When the name of a default content displayed in field 352 is selected and when the delete operation is performed while data corresponding to a My Selection packet have been displayed in field 351 with button 346 activated, the display program of operation instruction 112 will erase only the data of a content ID corresponding to a content belonging to the package included in the package display data 251, but no predetermined content stored in the content database 114. The presentation corresponding to a package of filtering and relating the filtering pack to a desired content: When the button 347 placed in the display window / operation instruction to display, in field 351, data corresponding to a filtering packet is activated, the display program / operation instruction displays, in field 351, packet names corresponding to the packet e filtering (for example, 'the 10 best pop songs', 'the 10 best rock and roll', 'the 10 best ENKA's', 'Love Songs Standards', 'Songs pops from the 80's recommended', etc. .), and, in field 352, names of contents belonging to the filtering packet corresponding to the package name selected as shown in Figure 34. Referring now to Figure 35, generation is explained of a filtration pack. The display program / operation instruction 112 generates packet display data 291-1 based on the content display data 221-1-1 to 221-Mp stored in the display data file 182 and stored history data in the history data file 184 or any of them and filtering data 551-1 stored in the filtering data filter 181. The packet display data 291-1 has stored there an ID for a content belonging to the corresponding filtration package. For example, packet display data 291-1 stores Ids for 10 predetermined contents (for example, those corresponding to the top 10 pops songs) designated with filtering data 551-1. The display program / operation instruction 112 generates packet display data 291-2 based on the content display data 221-1-1 to 221-Mp stored in the display data file 182 and stored history data in the history data file 184 or in any of them and filtering data 551-1-2 stored in the filtering data filter 181. The packet display data 291-2 has stored there an ID for a content that belongs to a package of corresponding filtration. For example, packet display data 291-2 stores Ids for contents whose names contain a predetermined string of characters eg, content names including the "love" characters designated by filtering data 551-2. similarly, the display program / operation instruction 112 generates package display data 291-3 through 291-A. Each of the package display data 291-3 through 291-A has there stored an ID for a content which belongs to a corresponding filtering packet For example, packet display data 291-4 stores Ids for 10 selected contents based on the history data stored in the history data file 184 and which have been extracted with greater frequency during the last week Likewise, the display program / operation instruction 112 generates 291-2 package display data based on display data. Content stream 221-1-1 to 221-Mp stored in the display data file 182 and history data stored in the history data file 184 or any of them and filtering data 551-1-1 to 551 -1-A stored in the filter data file 181.

The filtering data 551-1 to 551-A are downloaded from a predetermined server through the network 2, or supplied in accordance with what is registered in a predetermined CD from the unit 22. Likewise, the user himself can can generate the filtering data 551-1 to 551-A. For example, operating personal computer 1 to generate a new filtering packet by downloading and updating filtering data 551-1 to 551-A from more than one server through network 2 at a predetermined time Without modifying the content recorded in the content database 114, the user can use the new generated filtering packet to enjoy different combinations of contents. Next, an image displayed in field 348 will be described. As shown in FIG. 36, when a packet name displayed in field 351 is selected while a content name displayed in field 352 has not been selected (accordingly, a content has not been reproduced), the display program / operation instruction 112 displays in field 348 an image related to a packet corresponding to the selected package name. That is, with reference to data indicating the image file name stored in the package display data 211, 251 or 291, the display program / operation instruction 112 selects any of the image files 183-1 to 183-K, reads image data stored in the selected file from image files 183-1 to 183-K, and displays in field 348, an image corresponding to the image data. For example, when the package name 'Second' of the original package is selected while the content name displayed in field 352 is not selected, the display program / operation instruction 112 refers to data indicating a file name of image to a signal in the packet display data 211, reads image data stored in a predetermined file between the image files 183-1 to 183-K, which displays in field 348 an image corresponding to the image data Likewise, when a predetermined image is dragged and left in field 348 with the package name displayed in field 351 and selected and when the content name displayed in field 352 is not selected, the display program / instruction of operation 112 causes the dragged and left image to correspond to a packet corresponding to the selected packet name, i.e., the display instruction program / operation 112 converts the coding method through which the dragged and left image has been encoded to a predetermined method (e.g.

JPEG (Joint Photographic Experts Group) or similar), adjust the size of the image (for example to 30 pixels by 30 pixels or similar), subtract the colors (for example 256 colors or similar), record the image in the image file 183, and register the name of the image file 183 in which the image has been recorded as data indicating any image file name in the package display data 211, 251 or 291 corresponding to the package name. As shown in Figure 37, when a content name displayed in field 352 is selected as long as no content is reproduced, the display program / operation instruction 112 displays, in field 348, an image related to a content that corresponds to the selected content name. That is, the display program / operation instruction 112 refers to data indicating an image file name stored in the content display data 221 corresponding to the content corresponding to the selected content name, reads image data stored in a predetermined file of the image files 183-1 to 183-K, and displays, in a file 348, an image corresponding to the image data. For example, when the package name 'Second' of the original package is selected and the content name 'South Alps' displayed in field 352 is selected while the content "South Alps" has not been reproduced, the display program / operation instruction 112 refers to a corresponding image file stored in the content display data 221 corresponding to a content which corresponds to the content name 'Sout Alps', reads data from images stored in a predetermined file of the image files 183-1 to 183-K, and displays, in field 348, an image corresponding to the image data . At that time, when the button 345 is activated while data indicating an image file name are not set in the content display data 221 correspond to a content corresponding to a selected content name, the display program / instruction operation 112 refers to the data indicating an image file name stored in the content display data 221 to which it belongs, reads image data stored in a predetermined file archives 183-1 to 183- K, and displays, in field 348, an image corresponding to the image data. Similarly, when the button 346 is activated while no corresponding image file is set in the content display image 221 corresponding to a content corresponding to a selected content name, the display program / operation instruction 112 refers to data indicating an image file name stored in the package display data 251 to which the content belongs, reads data from images stored in a predetermined file of the image files 183-1 to 183-K, and displays, in field 348, an image corresponding to the image data. Similarly, when the button 347 is activated while no corresponding image file is set in the display and content data 221 corresponding to a content corresponding to a selected content name, the display program / operation instruction 112 refers to data indicating an image file name stored in the package display data 291 to which the image data content stored in a predetermined file of the image files 183-1 to 183-K belongs, and displays, in field 348, an image corresponding to the image data. Likewise, when a predetermined image is dragged and left in the field 348 while the content name displayed in the field 352 is selected, the display program / operation instruction 112 refers to the image dragged and left with corresponding content. to the selected content name. That is, the program display / operation instruction 112 converts the coding method through which the drag and drop image has been encoded to a predetermined encoding method, adjusts the size of the image, subtracts the colors, records the image in the image file 183 , and registers the name of the registered image file 183, wherein the image has been stored as data indicating any image file name in the image display data 221 corresponding to the content name. As shown in Figure 38, when a content corresponding to a content name displayed in field 352 has been reproduced (when a sound has been emitted from speaker 24), the display program / operation instruction 112 displays in field 348, an image indicating a signal level in each frequency band (i.e., in each eighth) of the output sound (i.e., image in a spectrum analyzer). Also, as shown in Figure 39, when a content corresponding to a content name displayed in field 352 has been displayed in accordance with a user setting, the display program / operation instruction 112 displays in the field 348 an image indicating a signal level corresponding to a period of time of the output sound during a predetermined period. Also, when the display program / operation instruction 112 does not display fields 351 and 352 in accordance with a user setting, the display program / operation instruction 112 will display, in field 348, an image indicating a level of signal in each frequency band of the output sound when a content has been reproduced, and an image corresponding to a selected package content when no content has been reproduced, as shown in Figures 40 and 41. Next, they will be described, with reference to the flow chart illustrated in Figure 42, operations for a recording performed when the display program / operation instruction 112 is initial booted with the content management display program 111 and the display program / operation instruction 112 installed on the personal computer 1. In step Sil, the display program / operation instruction 1 12 installed on the personal computer 1 refers to predetermined URL and network 2 and connects to the EMD registration server 3. In step S12, the display program / operation instruction 112, sends to the EMD registration server 3, the Content management program ID 111, previously stored in the content management program 111, together with the necessary data for registration (such as the name of a user of personal computer 1 and credit number). Note that in step S12, the display program / operation instruction 112 may send to the EMD registration server 3 the display program ID / operation instruction 112 previously stored in the display program / operation instruction 112 together with the necessary data for the registration. In step S13, the EMD registration server 3 receives the content management program 111. In step S14, the EMD registration server 3 determines whether the content management program ID 111 is valid. When it is determined that the content management program ID 111 is valid, the operation continues to step S15 where the EMD registration server 3 will register the user of the personal computer 1 based on the user's name and credit number. , and sends a predetermined number of authentication keys (use for mutual authentication with the EMD servers 4-1 to 4-3, for example) to the personal computer 1. In step S16, the display program / operation instruction 112 receives the predetermined number of authentication keys sent from the EMD registration server 3. In step S17, the EMD registration server 3 sends the EMD selection program 131 to the personal computer 1. In step S18, the display program / operation instruction 112 receives the EMD selection program 131 sent from the EMD registration server 3. In step S19, the display program / operation instruction 112 supplies the received EMD selection program 131 to the content management program 111. In step S20, the content management program 111 starts the EMD selection program 131. Thus, the Registration procedure is complete. If, in step S14 it is determined that the content management program ID 111 is not valid, the operation proceeds to step S21 where the EMD registration server 3 will send a predetermined error message to the personal computer 1 without make any record. In step S22, the display program / operation instruction 111 receives the error message sent from the EMD registration server 3. In step S23, the display program / operation instruction 112 displays the received error message. Thus, the procedure for registration has ended. When the display program / operation instruction 112 starts up, the personal computer 1 acquires the authentication keys used for mutual authentication with the EMD servers 4-1 to 4-3 and the selection program EMD 131, for example. Then, the record from a CD in accordance with the registration program 113 will be described with reference to the flow chart of Figure 43. In step S41, the registration program 113 activates the unit 22, reads data corresponding to a content registered on the CD placed in unit 22 (number of contents or playing time) and displays a list of contents registered on the CD in a predetermined window. In step S42, the registration program 113 determines whether the button 348 for information acquisition corresponding to the CD has been selected. When it is determined that the button 384 has been selected through the mouse, the operation proceeds to step S43 where the registration program 113 acquires the information corresponding to the CD. The acquisition of information corresponding to the CD will be described in more detail below with reference to the flow chart of Figure 44. In step S44, the registration program 113 displays in a predetermined window, the information corresponding to the CD, which has been acquired by the operation in step S43. If in step S42, it is determined that the button 384 for acquiring information corresponding to a CD has been selected, it is not necessary to acquire the information corresponding to the CD in such a way that the operation skips the steps S43 and S44 and proceeds to step S45. In step S45, the registration program 113 determines whether the button 386 for instruction to initiate registration of a content recorded on the CD has been selected by the mouse. If it is determined that button 386 has not been selected, the operation returns to step S45 where it is repeatedly determined whether button 386 has been selected by the mouse, until it is determined that button 386 has been selected. When it is determined, in step S45, that the button 386 has been selected through the mouse, the operation proceeds to step S46 where the registration program 113 will acquire, based on a revision acknowledgment corresponding to a name of content in field 383, content selection information that indicates which of the contents recorded on the CD can be registered. In step S47, the registration program 113 reads a content selected from the CD based on the content selection information. In step S48, the registration program 113 causes the compression method conversion program 134 in the content management program 111 to compress the content read from the CD through a predetermined conversion method such as ATRAC3. In step S49, the registration program 113 causes the encryption method conversion program 135 in the program content management 111 encrypt the compressed content through a default encryption method such as DES. In step S50, the registration program 113 causes the content database 114 to store the compressed and encrypted content. In step S451, the registration program 113 generates usage rule data corresponding to the content stored in the content database 114, and causes the content database 114 to store usage rule data generated in the use rule file 162 (in relation to the content stored in the content data base 114). In step S52, the registration program 113 updates the display data file 182 based on the usage rule data generated or information corresponding to the CD. In step S53, the registration program 113 determines whether the button 385 to establish an extraction, or no extraction of the content read from the CD 3nacia any of the portable devices 6-1 to 6-3 (automatic extraction) is activated . When it is determined that the button 385 is active, the operation proceeds to step S54 where the display program / instruction 112 starts. In step S55, the registration program 113 causes the display program / operation instruction 112 extract the content stored in the content database 114 to any of the portable devices 6-1 to 6-3. Thus, the procedure is complete. If it is determined in step S53 that button 385 is not active, it is not necessary to extract the content, the operation ends with skipping steps S54 and S55. When the record from the CD is made with the button 385 in active state, the personal computer stores the content read from the CD in the content database 114 and automatically extracts it to any of the portable devices 6-1 to 6-3. . Similarly, when the display program / operation instruction 112 receives content from any of the EMD servers 4-1 through 4-3 while a revision is performed with the 334 review button, it stores the received content in the base of content data 114 and causes the content management program 111 to extract content to any of the portable devices 6-1 to 6-3. Next the acquisition of information corresponding to a CD, made through the registration program 113 and in step S43 in Figure 43 will be described with reference to the flow chart of Figure 44: In step S71, the program Register 113 searches for information registered in a predetermined directory, (for example directory on hard disk drive 21, designated in field 404 in dialog box 461). In step S72, the registration program 113 determines based on data that corresponds to a content registered in a CD placed in the unit 22, (for example, number of contents in playback time), if the information corresponding to the CD is registered in the default directory. If it is determined that the information corresponding to the CD is not registered in the predetermined directory, the operation proceeds to step S73 where it is determined based on a series of characters found in field 401, if CDNEW has been selected. When it is determined in step S73 that CDNEW has been selected, the operation proceeds to step S74 where the registration program 113 will connect to a server corresponding to CDNEW (eg WWW server 5-2) through the network 2. In step S75, the registration program 113 causes the display unit 20 to display a screen for entering a keyword (for example, when the dialogue is shown in Figure 22). In step S76, the registration program 113 sends to a server corresponding to CDNEW, a search keyword entered based on the screen, for example the album name, artist name, content name, product number, or similar.

In step S77, the registration program 113 receives information corresponding to the CD from a server corresponding to CDNEW. In step S78, the registration program 113 relates the information corresponding to the content CD, and the procedure ends. If it is determined in step S73 that CDNEW has not been selected, the operation proceeds to step S79 since CDDB has been selected. In step S79, the registration program 113 connects to a server corresponding to CDDB (eg, WWW server 5-1) through the URL-based network 2 of the first CDDB side established in step 402 and the second URL. CDDB site established in field 403. In step S80, the registration program 113 sends to a server corresponding to CDDB, data corresponding to a playback time of a content registered in the CD. In step S81, the registration program 113 receives information corresponding to the CD from the server corresponding to CDDB. In step S82, the registration program 113 determines whether data corresponding to the CD received from the server corresponding to the CDDB includes more than two candidates. When it is determined that more than two candidates are available, the operation continues until step S83 wherein a table of Dialog will be displayed to allow the user to select the use or non-use of the information that corresponds to any CD. In step S84, the registration program 113 selects any of the candidates based on an entry to the dialog box, and the operation proceeds to step S78 where the registration program 113 relates the information corresponding to the CD to the content . This is how the procedure ends. If it is determined in step S82, that only two candidates are available, the operation proceeds to step S78 where the registration program 113 relates the information corresponding to the CD that has been received from the server corresponding to CDDB, and in this way the procedure is complete. When it is determined, in step S72, that the information corresponding to the CD is registered in a predetermined directory, the operation proceeds to step S85 where the registration program 113 reads the registered information corresponding to the CD and proceeds to step S78 where it relates the information read that corresponds to the CD with the content, and therefore the procedure ends. As in the previous case, the registration program 113 acquires information corresponding to CD of any of two or more different servers in a search procedure. Likewise, when the information corresponding to the CD has been acquired and registered, the registration program 113 uses the recorded information. Next, the generation of a flow packet made by the display program / operation instruction 112 will be described when the button 437 is selected, with reference to the flow diagram of Figure 45. In step S 101, the display program / operation instruction 112 selects a first filtering data 551, eg, filtering data 551-1, stored in filtering data file 181. In step S102, the display program / operation instruction 112 calculates a weight for the content based on data stored in the display data file 182 and history data stored in the history data file 184 or any of them and the selected filtering data 551. In step S103, the program display / operation instruction 112 a content belonging to a filtering packet corresponding to the selected filtering data 551 is selected with basis in weight for the content, calculated in step S102. In step S104, the display program / operation instruction 112 records the content that has been selected in step S103 in a filtration packet corresponding to the selected filtering data 551. That is, the display program / operation instruction 112 stores an ID for the selected content in the optionally replaced display data of packets 291 corresponding to the filtering packet corresponding to the selected filtering data 551. In step S105, the program display / operation instruction 112 determines whether the content has been recorded in the filtering packet corresponding to all the filter data 551 stored in the filtering data file 181. If it is determined that the content has not been registered in the filtering packet corresponding to all of the filtering data 551, the operation proceeds to step S107 wherein a next filtering data 551 stored in filtering data file 181 is selected and then returned to step S102 where it is will repeat the content record. If, in step S105, it is determined that the content has been recorded in a filtering packet corresponding to all the filtering data 551 the procedure ends. As above, the display program / operation instruction 112 will select a content based on data stored in the display data file 182 and history data stored in the data file of History 184 or any of them and the selected filtering data 551, and will record the selected content in the filtering packet. Next, it will be described with reference to the flow diagram of Figure 46 in extracting or entering content made by the display program / operation instruction 112 and content management program 111 when field 481 is displayed in the window display / operation instruction for example. In step S121, the display program / operation instruction 112 reads a number of possible extractions corresponding to the content of the display data file 18. In step S122, the display program / operation instruction 112 displays the number of possible extractions that has been read in step S121. In step S123, the display program / operation instruction 112 determines whether the extraction selection button 491 or the input selection button 492 has been selected through the mouse. When it is determined that button 491 or button 492 has been selected, the operation proceeds to step S124 where a content corresponding to a content name selected in field 352 is extracted or n where content is entered that corresponds to the content name selected in field 481. In step S125, the display program / operation instruction 112 updates the number of possible extractions in the content display data 222 in the display data file 182 corresponding to the setting of extraction of the content corresponding to the content name selected in field 352 or to the content entry establishment corresponding to the content name selected in step 481, which is done in step S124, and returns to step S121 where the same procedure will be repeated. If it is determined, in step S123 that none of the extraction adjustment button 491 or input adjustment button 492 has been selected by the mouse, the operation proceeds to step S126 where the display program / operation instruction 112 will determine if button 484 to perform the entry or extraction has been selected by the mouse. When it is determined in step S126 that the button 484 has been selected by the mouse, the operation proceeds to step S127 where the display program / operations instruction 112 will cause the revenue / extraction management program 132 in the program of content management 111 perform the extraction or entry corresponding to the adjustment of the extraction or entry of content. The revenue / extraction management program 132 determines, based on the usage rule data stored in the usage rule file 162 whether each content can be extracted or entered. When the program 132 determines that it is possible to extract or enter said content, it will do so. When it is determined that income extraction is not possible, the income / extraction management program 132 will not do so. In step S128, the display program / operation instruction 112 causes the input / extraction management program 132 in the content management program 111 to update the number of possible extractions for the usage rule data stored in the file of rules of use 162 in the content database 114 (corresponding to a content extracted or entered) corresponding to the execution of the extraction or entry of the content. In step S129, the display program / operation instruction 112 causes the input / extraction management program 132 to read the number of possible extractions from the usage rule data stored in the usage rules file 162, corresponding to the content extracted or entered. In step S130, the display program / instruction of operation 112 updates the number of possible extractions related in the history data file 184, and updates the content display data 221 in the display data file 182 based on the number of possible extractions that has been read in step S129. Then return to step S121 where the same procedure is repeated. When it is determined, in step S126, that the button 484 has not been selected through the mouse, no extraction or no entry is made. Thus, the operation returns to step S121 where the same procedure is repeated. As in the previous case, the display program / operation instruction 112 changes the display correspondingly to the extraction or entry determination, and causes the content management program 111 to execute an extraction or an entry based on the determination of extraction or income. Next, the image glue, performed by the display program / operation instruction 112, will be described when a predetermined image has been dragged and left in field 348, with reference to the flow diagram of FIG. 47. In step S151, the display program / operation instruction 112 determines whether a package has been selected. When it is determined that a package has been selected, the program proceeds to step S152 where the dragged and dropped image will be changed to a predetermined size, and subjected to a color coding and subtraction method conversion. In step S153, the display program / operation instruction 112 stores the image subjected to the color coding and subtraction method conversion in step S152 in the image file 183. In step S154, the display program / Operation instruction 112 determines whether a content has been selected. When it is determined that no content has been selected, the operation proceeds to step S155 where the image file 183 and the selected packet will be related to each other (i.e., the name of the image file 183 where the content is registered). records as data indicating a file name of images in any of the packet display data 211, 251 or 291 corresponding to the selected packet), and thus the procedure ends. If it is determined, in step S154, that a content has been selected, the operation proceeds I to step S156 where the display program / operation instruction 112 relates the image file 183 to the selected content (i.e. the name from the image file 183 in which the content is recorded is recorded as data indicating an image file name in the content display data 221 corresponding to the selected content), and thus the procedure ends. If it is determined, in step S151, that no packet has been selected, there is no object with which the image is related, such that the operation proceeds to step S157 where the display program / operation instruction 112 will display a default error message and therefore the procedure ends. As in the previous case, the display program / operation instruction 112 can paste the dragged and left image into a package or content (image and package or content are related to each other). Next, the image display performed by the display program / operation instruction 112 will be described with reference to the flow diagram of Figure 48. In step S181, the display program / operation instruction 112 determines whether a content has been reproduced If it is determined that no content has been reproduced, the operation proceeds to step S182 where it is determined whether a package has been selected. If it is determined, in step S182, that no packet has been selected, the operation proceeds to step S183 where the display program / operation instruction 112 will display, in field 348, a predetermined image (e.g., an image showing the provider of the display program / operation instruction 112) and the operation will return to step S181 where the same procedure will be repeated. When it is determined, in step S182, that a packet has been selected, the operation proceeds to step S184, wherein the display program / operation instruction 112 is determined if a content has been selected. If it is determined, that in step S184, that no content has been selected, the operation proceeds to step S185, where the display program / operation instruction 112 will display, in field 348 an image related to the selected package ( the display program / operation instruction 112 refers to data indicating an image file name stored in the packet display data 211, reads image data stored in a predetermined file among the image files 183-1 to 183 -K, and displays in field 348, an image corresponding to the image data), and returns to step S181 where it repeats the same procedure. If it is determined, in step S184, that a content has been selected, the operation proceeds to step S186 where the display program / operation instruction 112 will determine whether an image related to the content selected is available. If it is determined, in step S186, that there is an image related to the selected content, the operation proceeds to step S187 where the display program / operation instruction 112 displays, in field 348, the image related to the content selected (the display program / operation instruction 112 refers to data indicating an image file name stored in the content display data 221 corresponding to the selected content, reads image data stored in a predetermined file among the files of images 183-1 to 183-K, and displays, in field 348, an image corresponding to the image data), and proceeds to step S181 where the same procedure is repeated. If it is determined, in step S186, that there is no image related to the selected content, the operation proceeds to step S188 where the display program / operation instruction 112 will display in field 348, an image related to the content selected. Then the operation returns to step S181 where the same procedure is repeated. If it is determined, in S181, that a content has been reproduced, the operation proceeds to step S189 where the display program / operation instruction 112 will determine whether the display of a signal level of a sound corresponding to each frequency band has been established. If it is determined that the display has been established, the operation proceeds to step S190 where the signal level of a sound corresponding to each frequency band will be displayed in field 348. The operation returns to step S181 where the same procedure is repeated. If it is determined, in step S189, that the display of a signal level of a sound corresponding to each frequency band has not been established, the operation proceeds to step S191 where the display program / operation instruction 112 displays, in field 348, a waveform of an output sound (signal level corresponding to a period of time of the output sound), and returns to step S181 where the same procedure is repeated. As in the previous case, corresponding to the selection of a content package or the reproduction of a content, the display program / operation instruction 112 will display, in field 348, any image related to the package, image related to the content, signal level of a sound that corresponds to each frequency band and a waveform of the output sound. In the previous description, with reference to the diagram flow of Figure 43, when the button 385 is set as active in the record from the CD by the registration program 113, the personal computer 1 extracts all the contents read from the CD to any of the portable devices 6-1 to 6 -3 after reading. However, it may also be possible that, after reading a content from the CD, the extraction of the already read content begins at the same time that the reading of the following content begins. Figure 49 illustrates an example of a window presented in the display 20 by a registration program 113 when the registration program 113 starts in a case in which the content reading and the extraction of the recorded content are executed at the same time. In the window shown in Figure 49 there is added a registered side display column 601, a register status display bar 602 and a register status display column 603 to the window illustrated in Figure 16. The The registered side display 601 visually presents devices on the registered side and presents 'HDD and portable device 6-1' in the present case Thus, it shows that the button 385 is selected by the mouse and that the portable device 6-1 is selected from portable devices 6-1 to 6-3 to be removed. same, 'HDD' is displayed as a registered side of the content, that is, when 'no extraction' is selected from the selection menu, only "OD" is displayed in the display column of the registered side 601. When selected any of the portable devices 6-1 to 6-3 (in the present case), the selected portable device as well as the HDD is displayed in the display column of the registered side 601. The registration status display bar 602 presents the proportion of the respective processes in relation to the entire process including the process of registering all the selected content and the extraction process, to show a progress status of the process where the contents are recorded and a progress status of the process where the Registered contents are extracted, for example, when the button 386 to start the process is selected through the mouse in a state in which it is selected. Check boxes for view numbers 5, 7, 9 to 11 in field 383 (the other contents are already registered), that is, in a state in which the five contents are registered to start the registration as shown in Figure 49, the bars to show the progress status of the respective processes of the record and the extraction are displayed as shown in Figure 50. That is, in the registration status display bar 602 there is a red portion 602a showing the progress status of the registration process and a brown portion 602b showing the progress status of the extraction, and as the processes progress, the portions move from the left to the right in the figure. When the red portion 602a and the brown portion 602b are displayed in the entire area of the register status display bar 602, it shows that the entire process (the process of recording the contents of the tracks 5, 7, 9 to 11 and the extraction process of all the contents recorded in the present case) ends. In the present case, approximately half of the whole is finished (the red portion 602a is displayed, starting from the left approximately in the central portion of the registration status display bar 602) in the content registration process, while approximately a quarter of the total is finished (the brown portion 602b is displayed in the portion representing a quarter from the left of the registration status display bar 602) in the process of extracting the Registered contents Meanwhile, as the process of registering the contents is carried out before the process of extracting the recorded contents, the red portion 602a is displayed in the registration status display bar 602a. first and then the brown portion 602b standing on the red portion 602a. As a result, when the entire process is finished, only the brown portion 602b is displayed in the registration status display bar 602. It will be noted that another combination of colors as well as red and brown may be possible in relation to The colors displayed in the bar are displayed in register status 602. The register status display column 6C3 is displayed as an active state while the registration and extraction processes are taking place (for example, 'in the process of registration'). "is expressed in a reverse state as shown in Figure 50. When the extraction process is in progress, the registration program 113 displays a dialog box 611 in the window to show that the process is taking place, as shown in FIG. Figure 50. In dialog box 611, the following is displayed: 'The input / extraction process is being carried out, please do not disconnect the devices or media external (will cause an interruption) "and a status display of input / extraction status 611a below. The entry / extraction status display bar 611a shows the input / extraction progress status for a content, and the bar displayed there continues from the left to the right as the process progresses. income / extraction. For example, in the present case the '30% 'is displayed to show that 30% of the content of track number 9 is already registered (30% of the process of registering the content of track number 9 is finished) is shown in field 383. Thus, since the tracks number 5 and 7 are already registered, the progress status of the process of extracting the content in any of the tracks number 5 or 7 that is the registered content is shown in the display bar 611. The dialog box 611, which shows that the process is in progress, is hidden when the extraction of each content ends, and it is displayed again when the next extraction is started (that is, the The dialog is alternatively displayed and hidden while the extraction is taking place.) Also, below the 611a input / extraction status display bar, a revision table 611b is provided, beside which it is visualized. iza 'This message will not be visualized in the future. " If the revision box 611b is selected, the dialog box 611 is set in such a way that it is not displayed in future registration processes. When a button is selected through the mouse 611c shown as 'interrupt', the registration status (including the extraction process is suspended). Likewise, when a 611d button is selected shown as "Hidden display" hides the visualization of the dialog box 611 in processing Next, a simultaneous extraction process in which registered contents are extracted at the same time as the contents are extracted will be described with reference to the flow chart of Figure 51. registered In the step S201, the registration program 113 reads contents selected from the CD based on the content selection information In one case in Figure 49, the contents corresponding to the tracks numbers 5, 7, 9 to 11 are read from the CD In step S202, the registration program 113 allows the compression method conversion program 134 of the content management program 111 to compress the contents read from the CD in a predetermined method, for example, ATRAC 3. In step S203, the registration program 113 allows the encryption program 135 of the content management program 113 to encrypt the compressed contents in a predetermined method, for example, DES. In step S204, the registration program 113 allows the content database 114 to store the data contained and encoded therein. In step S205, the registration program 113 generates the usage rule data corresponding to the contents stored in the content database 114 and allows the content database 114 to store the usage rule data generated in the usage rule file 162. Similarly, the registration program 113 updates the display data file 182 based on the rule data of use generated or based on the information corresponding to the CD. In step S206, the registration program 113 determines whether or not the registration of a track has been terminated and proceeds with processing until the registration of a track is completed. If it is determined, in step S206 that the registration of a track has terminated, the registration program 113 adds the recorded contents to the list of extraction processes possessed by the display program / operation instruction 112 in step S207. In step S208, the display program / operation instruction 112 determines whether or not the extraction process is running through the content management program 111. If the display program / operation instruction 112 determines that said process of extraction is in the process of execution, the process proceeds to step S209. In step S209, the registration program 113 determines whether or not the registration of all the tracks has ended. If it is determined that the record of all the tracks has not yet been completed, the process returns to step S201 to repeat the Next steps. If it is determined that the extraction process has not been executed in step S209, the display program / operation instruction 112 allows the content management program 111 to execute (start) the extraction process. The extraction process will be explained below with reference to a flow chart of Figure 52. The process is initiated by the process in the previous step S210. In step S221, the content management program 111 determines whether or not the contents to be extracted are entered (written) in the extraction process list that the display program / operation instruction 112 has. If it is determined that there are contents to extract, the process proceeds to step S222. In step S222, the content management program 111 allows a predetermined portable device to extract the contents entered in the extraction process list. In step S223, the content management program 111 determines whether or not the extraction has been complete, and repeats the process until its completion. If it is determined that the process has ended, the process proceeds to step S224. In step S224 the content management program 111 allows the display program / operation instruction 112 to delete the contents entered in the extraction process list, and for the process to return to step S221 to repeat the following steps. If it is determined in step S221 that the contents to be extracted are not entered in the list of extraction processes, the process ends. It may be possible, when the recording of the content and the extraction are carried out simultaneously (when the extraction process is carried out as a background process) in accordance with what is described above, the reproduction process takes place during the registration process and extraction in relation to the contents in which registration and extraction are commanded simultaneously, for example, lanes numbers 5, 7, 9 to 11 where review tables are selected as shown in Figure 49. It is preferred that the simultaneous process of the content and extraction record (process in the flow diagram in Figure 51) and the collective extraction process after registering all the contents are used selectively according to the environment of use. For example, if mutual authentication between personal computer 1 and portable devices 6-1 to 6-3 is required in the extraction process, mutual authentication must be performed each time a content is extracted. Therefore, when the portable device can not perform the mutual authentication process of high-speed extraction, the collective extraction process after registration of all contents is preferably selected to accelerate the entire process. Note that in accordance with a setting made by the user, the display program / operation instruction 112 may display in field 348, an image indicating the level of a sound currently extracted when a content has been reproduced. Likewise, it will be noted that even though it has been accurately described that the content compression method adopted by the personal computer 1 is ATRAC3, by way of example, the method is not limited to ATRAC3 but can be any of MP3 (Moving Picture Experts Group 2 Audio Layer 3), TwinQV (registered trademark), AAC (MPEG2 Advance Audio Coding), etc. Note that even though it has been previously described that the content encryption method adopted by personal computer 1 is DES as for example, the method is not limited to DES, but can be any of IDEA (International Data Encryption Algorithm), RAS which is a public key encryption method, elliptical encryption, etc. Likewise, the content management program 111 can be executed in a provided equipment independently within the personal computer 1, and that the content management program 111 can not directly read. Likewise, the equipment for executing the content management program 111 can be designed in such a way that it has resistance to unauthorized use. The aforementioned series of operations can be carried out through a team, but can also be executed through a programmatic one. If the series of operations must be executed through a programmatic, programs that make up the programmatic are installed from a program storage medium, in a computer incorporated in a dedicated computer or in a personal computer for general purposes, for example , whose various functions can be performed with several programs installed there. The storage medium for programs for storing programs installed on a computer and which can be executed from the computer can be formed of a magnetic disk 41 or 91 (including a floppy disk), optical disk 42 or 92 (including CD-ROM ( compact read-only memory disk), DVD (versatile digital disk), magneto-optical disk 43 or 49 (including MD (mini disk)), packaging medium such as semiconductor memory 44 or 94, ROM 12 or 62 , where the programs will be stored provisionally or permanently, or HDD 21 0 71, as shown in Figures 2 and 3. The programs are stored in the program storage medium through an interface such as, for example, communication unit 25 or 73, using a means of communication by cable or radio, such as network 2. which includes a local area network or Internet, or digital satellite broadcasting. Note that the operation steps with reference to a program stored in the program storage medium, described herein, include operations performed in series in time in the described sequence as well as operations not performed in series over time but in parallel or individually. I Note also that the "system" mentioned herein encompasses a complete set of several apparatuses Industrial Exploitation As described above, in accordance with the present invention, when at least one of at least two contents to be registered has been registered in the registration step in the registration medium and the registration of the other content has started, the content is extracted to a device connected to an information processor that carries out the method or program, so that the registered content can be extracted quickly.
