FIG. 5 is an explanatory diagram showing an example of processing operation of the in-center mediation server in FIG. 2, and FIG. 6 is an illustration of processing operation of the in-center mediation server in FIG. FIG. 7 is an explanatory diagram showing a detailed example and a processing operation example of the terminal device corresponding thereto, FIG. 7 is an explanatory diagram showing a format example of transmission data transmitted and received by the intermediary server in the center in FIG. 5, and FIG. 8 is a center in FIG. It is explanatory drawing which shows the structural example of the check table managed by the internal mediation server.

  In the remote operation technology described below with reference to FIGS. 2 to 8, the operation of the computer devices 1 a to 1 d (center management personally owned PC) from the terminal devices 2 a to 2 c (remote control terminal PC) is performed using a network using the Internet network. Done via. By using the Internet network in this way, if there is a terminal device (remote control terminal PC), the user can maintain and manage his / her own computer device (center-managed personally owned PC) and an individual anywhere in the world. Data can be used. In addition, data loss due to theft, loss, or physical damage of a mobile PC such as a notebook PC can be avoided.

  First, signal transmission in the remote control system in FIG. 2 will be described. The input / output control signals flowing in the network are transmitted in the upward direction from the terminal device (described as “remote control terminal PC” in the figure) 2a to the computer devices (described as “center management personally-owned PC” in the figure) 1a to 1d. In the input information for control from a mouse, a keyboard or the like, the down direction from the computer devices 1a to 1d to the terminal device 2a is output information such as screen information and audio information as a result of control.

  The dedicated adapter 1i is a device for converting input / output signals from the computer devices 1a to 1d into a network transmission format. The dedicated adapter 1i can be replaced by software processing in the computer devices 1a to 1d when the CPU power of the computer devices 1a to 1d is sufficient. The in-center mediation server 1j is a computer device provided with a function for mediating between the center side and an external network, such as authentication of a user who operates remotely.

  Dedicated software for remotely operating the computer devices 1a to 1d is installed in the terminal device 2a. The router 3 or the modem, the provider device (described as “provider” in the figure) 21, and the Internet network 20 are existing devices and services, and perform functions as usual.

  Hereinafter, the dedicated adapter 1i will be described with reference to FIG. A dedicated adapter 1i having an internal configuration shown in FIG. 3 is a device for connecting the computer devices 1a to 1d to the in-center mediation server 1j. The LAN board 32 for connection to the in-center mediation server 1j and the computer devices 1a to 1d A main board 31 having a USB 2.0 terminal 34 and a monitor input terminal 35 for interfacing with 1d, and further comprising a functional block for performing signal conversion between LAN and USB, and a functional block for performing MPEG4 video encoding; And a DC converter 33 for converting the AC power into DC.

  The signals flowing in the USB 2.0 cable connected to the USB 2.0 terminal 34 of the dedicated adapter 1i are “mouse control signal (compatible with existing USB mouse)” and “keyboard control signal (compatible with existing USB keyboard). "," Audio signal from PC (compatible with existing USB speakers) "," Current position of mouse cursor from PC (X position, Y position) ", etc., and monitor connected to monitor input terminal 35 As a signal flowing in the connection cable, there is “screen information from PC (compatible with existing VGA or DVI)”.

  A LAN cable is used for the interface with the intermediary server 1j in the center, and the “mouse control signal (compatible with the existing USB mouse)” converted by the LAN / USB signal conversion function block is used for this LAN cable. “Keyboard control signal (compatible with existing USB keyboard)” and “Audio signal from PC (compatible with existing USB speakers)” and “screen from PC” compressed with MPEG4 moving image encoding function block "Information (compatible with existing VGA or DVI)".

  Next, contents and paths of control input / output signals exchanged between the terminal devices 43 (2a to 2c) and the computer devices 41 (1a to 1d) will be described with reference to FIG. In particular, the processing contents through the dedicated adapter 42 (1i) shown in FIG. 2 will be described.

  In FIG. 4b, a user who has contracted to receive the provision of a centralized computer operation service on the center side operates a mouse and a keyboard based on information displayed on the screen of the terminal device 43, The terminal device 43 converts this operation content into a LAN signal and transmits it via the Internet (20).

  4A, in the computer centralized operation center system (1), the user operation information from the terminal device 43 is received by the mediation server (1j) in the center and is taken into the dedicated adapter. The dedicated adapter 42 decodes the captured user operation information (LAN signal) into a mouse / keyboard operation signal, and then passes it to the computer device 41 with which the user has a contract.

  The computer device 41 performs processing based on the mouse / keyboard operation signal, outputs a screen and sound reflecting the signal contents, compresses the processing result in a moving image in the dedicated adapter 42, and performs intermediary server (1j) ) To the terminal device 43 via the Internet (20). In FIG. 4B, the terminal device 43 displays and outputs a screen on which the result of the user operation on the own device is fed back.

  Next, the in-center mediation server 1j in FIG. 2 will be described with reference to FIG. The role of the intermediary server 53 (1j) in the center is data mediation between the dedicated adapter 51 (42, 1i) and the terminal device 55 (43, 2a), and between the LAN (1) 52 in the center and the Internet network 54. The gateway function converts the destination IP address, and the upstream transmission data is transmitted to the dedicated adapter 51 and the downstream transmission data is transmitted to the terminal device 55.

  The intra-center mediation server 53 has a user authentication function using a check table (TBL), and an example of an authentication processing operation by this user authentication function will be described with reference to FIG. FIG. 6 shows a processing procedure of user authentication performed between the intermediary server 53 in the center and the terminal device 55, and mutual communication is added to the headers of “uplink transmission data” and “downlink transmission data”. Controlled by a disposable account.

  That is, as shown in FIG. 6a, when the intermediary server 53 in the center receives the uplink transmission data from the terminal device 55 (step S601), it determines the account with reference to the check TBL (step S602) and is effective. In such a case, after the upstream transmission data is mediated to the dedicated adapter 51 (step S603), a new account is issued if necessary according to the account deadline (steps S604 and 605). In addition, it mediates to the terminal device 55.

  If the account is not valid in step S602, user authentication is performed using the user ID and password (step S609). If the authentication is successful, the process proceeds to step S605. If the authentication is not successful, the terminal of the downlink transmission data is obtained. The mediation to the device 55 is stopped (step S607).

  As shown in FIG. 6b, the terminal device (remote control side PC) 55 sends the upstream transmission data to the intra-center mediation server 53 to perform user authentication (steps S610 and S611). The added new account is added to the upstream transmission data to continue communication with the in-center mediation server 53 (steps S612 to S615).

  Since the account has an expiration date and is updated every time communication is performed, it is possible to prevent unauthorized access due to impersonation of another person that may occur if the account leaks to the outside. Further, by appropriately shortening the expiration date of the account, it is possible to stop transmission of “downlink transmission data” when the remote operation is not performed, and to reduce the load on the network.

  A format (example) of such transmission data will be described with reference to FIG. As shown in FIG. 7, an account is added to the header of the transmission data for both upstream and downstream, and is used for user authentication in the center mediation server 53. RQ (request code) is a code indicating the data content of transmission data. In FIG. 7, '01' to '40' are uplink transmission data and '80' to '90' are downlink transmission data. Of the upstream transmission data, the destination of “30” “media exchange” is transmitted not to the dedicated adapter 51 but to the file server of the shared storage device (shared disk).

  FIG. 8 shows a configuration example of a check table 81 (check TBL) provided in the intra-center mediation server 53 in FIG. 5, and this check table 81 includes an account table (TBL) 82 and a user ID table (TBL). 83 and three databases of a dedicated adapter table (TBL) 84.

  When logging in for the first time, a record of the account table 82 is generated from the user ID table 83 and the dedicated adapter table 84. The account added to the transmission data is checked by determining whether the account exists in the account table 82 and the effective date and time. When the account is reissued, the old account is discarded and deleted from the account table 82.

  Next, the centralized management operation of each computer apparatus of the computer centralized operation center system in FIG. 1 will be described with reference to FIGS. Thus, by centrally managing a plurality of personally owned computer devices at the center, the user (user) can obtain the following merits.

  That is, the user does not have to place the hardware to be used at home (workplace). This eliminates the need to secure the installation location of the computer device, secure a large-capacity power supply, and prevent cooling fan noise. In addition, since the initial setting / part replacement of the computer device is performed on the center side, the user can use the latest or special hardware without hardware expertise. Furthermore, since the board in the computer apparatus is replaced on the center side, the user side does not need to make a repair request or prepare a substitute PC when a hardware failure occurs. Further, since the shared disk is maintained on the center side and the backup of the dedicated disk is also performed via the shared disk, the user can obtain a safe, simple, and reliable data maintenance service.

  9 is an explanatory diagram showing an example of the management configuration of the computer apparatus in the computer management service network system in FIG. 1, FIG. 10 is a block diagram showing an example of the configuration of the disk connection apparatus in FIG. 9, and FIG. 10 is an explanatory diagram showing an example of processing functions of the disk connection device in FIG. 10, and FIG. 12 is an explanatory diagram showing an example of usage of the disk connection device in FIG.

  In FIG. 9, in order to centrally manage a plurality of computer devices (center management personally owned PCs), each computer device is constituted by a board 92b composed of a mother boat and a video cart, and is stored together in a storage rack 92. Yes. This saves installation space and improves maintainability. The computer function of each computer device (substrate 92b) is not changed from that of a normal computer, and a commercially available PC substrate can be used as it is. In addition, a dedicated adapter 92a and a disk connection device 92c are connected to the external intermediary center server 91, the shared disk management file server 93, and the shared disk storage rack 94 storing a plurality of general-purpose PC 5-inch hard disks. Via the intra-center LAN.

  The dedicated adapter 92a has already been described with reference to FIGS. 2 to 4 and the like, and the disk connection device 92c will be described below. Since the computer apparatus (center management personally owned PC) is remotely operated, an external storage device using an exchangeable recording medium such as a CD-ROM cannot be used, so it is connected to the disk connection device 92c as an alternative.

  As shown in FIG. 10, the disk connection device 92c includes a main board 921, a LAN board 922, a DC converter 923, and a hard disk 924, and is connected to a serial ATA (ATA attachment) (1) 1002, (2) for connection to a computer device. ) 1001.

  The serial ATA (1) 1002 is connected to a built-in dedicated hard disk 924 (PC startup system drive) and assigned to a drive. The serial ATA (2) 1001 is connected to the LAN device / serial ATA signal conversion function block on the main board 921, and is assigned to a shared storage device (shared disk) via the LAN via the LAN board 922. Also, it has a CD / DVD emulator function as means for accessing data stored in a shared storage device (shared disk).

  As a signal flowing through the serial ATA (1) cable via the serial ATA (1) 1002, there is a hard disk signal corresponding to the serial ATA, and format conversion for this signal is unnecessary. In addition, as a signal flowing in the serial ATA (2) cable via the serial ATA (2) 1001, a signal compatible with a serial ATA compatible CD / DVD signal (during CD / DVD emulation), a serial ATA compatible signal There is a signal that is compatible with the hard disk signal (when accessing a file on the shared disk), and a LAN cable is used as an interface with the shared storage device (shared disk), and the serial ATA (2) described above is used for this LAN cable. A signal flows through the cable.

  An example of the processing operation of the disk connection device 92c having such a configuration will be described with reference to FIG. The signal via the serial ATA (1) from the computer device (center management personally owned PC) is directly passed to the dedicated disk 924, and the signal via the serial ATA (2) is sent to the CD / DVD emulator in the internal signal converter 925. The signal is divided into a signal passed to 926 and a signal passed to the LAN / serial ATA signal conversion processing unit 927.

  The LAN / serial ATA signal conversion processing unit 927 converts the serial ATA (2) signal into a LAN signal and manages it on the shared storage device (shared disk) managed by the disk management device (shared disk management file server 93) 1102. Files (CD / DVD image file 1103, shared file 1104) can be handled as files on a normal hard disk.

  The CD / DVD emulator 926 performs an emulation process for causing the computer device (center management personally owned PC) to recognize the CD / DVD image file 1103 on the shared storage device (shared disk) as an actual CD / DVD medium. Note that a technique for causing a computer to recognize such a CD / DVD image file as a CD / DVD is possible with commercially available software.

  Next, a usage form of the disk connection device 92c will be described with reference to FIG. FIG. 12 shows an example of using a CD / DVD medium at the time of CD / DVD emulation. Various CD / DVD image files are stored on the shared disk 1201, and a terminal device (remote control terminal PC) 1204 is stored. The user on the remote side can use only those who have the license 1202 among them.

  The media exchange is performed by selecting a media name from the possessed license list, and an exchange instruction is given from the terminal device (remote control terminal PC) 1204 to the shared disk 1201 via the center intermediary server 1203. For example, when the computer device (center management personally owned PC) 1101 is reset from the OS, the current media on the shared disk 1201 is set to the OS CD-ROM, and the boot drive for starting the PC is dedicated on the BIOS setting screen. By changing from the disk (C drive) 924 to the CD / DVD emulator drive (D drive) 926 and restarting, the installation process from the OS CD-ROM can be started.

  Next, the management operation of the shared storage device (shared disk) of the computer centralized operation center system 1 in FIG. 1 will be described using FIG. 13 and FIG. In the centralized computer operation center system 1 of this example, the disk management device 1f centrally manages the data possessed by each user on the shared disk, thereby eliminating duplicate files and similar files, and limited physical storage. With the capacity, the logical storage capacity per user can be dramatically increased. In addition, even when a file is exchanged between remote users, since it is performed in the center and does not go through the Internet, there is an advantage that the communication time due to a delay in network transmission is close to zero.

  FIG. 13 is an explanatory diagram showing an example of file management in the shared recording device of the computer management service network system in FIG. 1, and FIG. 14 is a flowchart showing an example of processing operation of the disk management device in FIG.

  Differences between the shared storage device (shared disk) and the dedicated storage device (dedicated disk) will be described with reference to FIG. 13 (1) shows the structure of a file management system of a conventional file management system, and FIG. 13 (2) shows the structure of a shared disk file management system.

  In the conventional file management system shown in (1) of FIG. 13, there is no function to check even if duplicate files (“A”) and similar files (“B”, “B ′”) exist on the same volume. However, in the shared disk file management system of this example shown in (2) of FIG. 13, the entity file is managed via the property information. For this reason, when registering a file, there is no need to store the actual file by consuming the disk area allocated exclusively for itself.

  In such a file management technique, as the number of remote users who use a shared disk increases, the sharing probability of the actual file and the number of simultaneous shares increase, and the consumption of physical disk space can be saved. Note that a technique for eliminating duplicate files and similar files used for disk sharing has already been described as a data compression technique, and will not be described here.

  Note that data not to be shared is stored in a dedicated disk in the same manner as in a conventional file management system. The reason for the existence of such a dedicated disk in the PC centralized management system is that the access user is narrowed down to the owner in comparison with the shared disk, so that the security is excellent and the file management system is simple. Yes, the disk access performance is high. The purpose of the dedicated disk is to install a system drive (for example, C drive) that is always dedicated to the OS of the computer device (center management personally owned PC), or to store unique and non-public data owned by a corporate user. .

  It should be noted that merely excluding duplicate files and similar files existing on the shared disk is not sufficient for improving the disk utilization efficiency. For example, as shown in FIG. Sometimes the user is notified in advance of the number of occurrences of file sharing, and if the number of disk sharing increases to n, the disk consumption (≈ billing) will also be reduced to 1 / n. It is effective to promote unification of storage formats (compression / archive format, etc.).

  In FIG. 14, when a registered file designation is received from the user (step S1401), a file that is duplicated or similar to the file on the shared disk is searched and investigated (step S1402), and the number of shares is totaled ( In step S1403), the consumed disk amount is calculated (step S1404), and the calculation result is displayed as a message on the screen of the user terminal (step S1405).

  When the user selects a registration instruction as a duplicate file or similar file on the shared disk of the file with reference to the message (confirmation of file registration) 1400 displayed in this way (step S1406), the file is stored on the shared disk. Are registered as duplicate files and similar files (step S1407).

  If the number of shared disk users increases after registration of such duplicate files, the disk consumption of the next month will decrease from the displayed value. Conversely, if the number of shared users decreases, the disk consumption of the next month will increase from the displayed value. .

  Next, the copyright protection management operation using the shared storage device (shared disk) of the computer centralized operation center system 1 in FIG. 1 will be described with reference to FIGS. In the centralized computer operation center system 1 of this example, CD-ROM data for installation of commercial applications and commercial copyright data that are run on each of the computer devices 1a to 1d are stored in a shared disk that is centrally managed by the disk management device 1f. . This eliminates the need to obtain a copy for backup or to move data to a removable medium or the like in order to avoid a shortage of disk capacity in the computer apparatuses 1a to 1d, thereby facilitating copyright protection measures. .

  15 is an explanatory diagram showing an example of folder management of the shared storage device by the disk management device in FIG. 1, and FIG. 16 is a flowchart showing an example of access control processing to the shared storage device by the disk management device in FIG. .

  First, an example of copyright protection technology using a shared storage device (shared disk) 1501 will be described with reference to FIG. In this example, the files in the shared storage device (shared disk) 1501 are managed by dividing them into attributes of the center management folder 1502 and the personal management folder 1503. The center management folder 1502 stores data that should not be copied, such as commercial applications, and the personal management folder 1503 stores personal data.

  Here, by prohibiting the downloading of files other than the files in the personal management folder 1503 to the terminal device (remote control terminal PC) 1504 (2a to 2c), illegal data copying and the computer centralized operation center system (1 ) Can be prevented from flowing out. A file operation tool for performing such control will be described with reference to FIG.

  FIG. 16 shows an example of the processing procedure of the file operation tool according to the present invention. The conventional file operation tool also has a function of prohibiting copying by providing a restriction of “reference authority only (read only)”. However, the personal file management tool 1502 in the same storage device (shared disk) Data copy to the management folder 1503 is possible.

  According to the file operation tool of this example, at the time of start-up, the program itself is checked to confirm whether or not modification has been added (step S1601). After that, the license owned by the user is confirmed, and the center management folder and personal management folder owned by the user are displayed (steps S1603 and S1604).

  When the user selects a file (step S1605), it is determined whether the file is in the center management folder 1502 or the personal management folder 1503 based on the property information of the selected file (step S1606), and the file in the center management folder 1503 is determined. If so, file operation functions such as copy, drag and drop, and download are invalidated (steps S1607 and S1608).

  Further, applications that can be activated in association from file attributes (extensions) are also limited to reproduction-only applications that take into account copyright protection designated by the center (step S1609). For example, copyright data README. The program for checking the contents of TXT is not a text editor that can save a file in another area, but a text viewer that cannot copy and paste the selected character string or save the file.

  Then, a file operation corresponding to the user's remote operation is performed (step S1610). In the determination process in step S1606, if the selected file is a file in the personal management folder 1503, the file operation function restriction in steps S1607 to S1608 is not performed.

  Next, the operation of effectively using surplus CPU power by the computer centralized operation center system 1 in FIG. 1 will be described with reference to FIGS. Since the computer devices 1a to 1d managed by the computer centralized operation center system 1 do not always use 100% of the CPU, the surplus CPU power can be allocated to other uses such as scientific and technical calculations. .

  For example, SETI (Search for Extra-Terrestrial Intelligence) that searches for extraterrestrial civilization using a large number of computers connected to the Internet is known as a conventional technique for effectively utilizing such surplus CPU power. In this example, the computer devices 1a to 1d managed by the computer centralized operation center system 1 have high-speed access to the network resources in the center outside the computer device, so calculation by data I / O (input / output) etc. There are few occurrence points of processing bottlenecks, the surplus CPU power can be systematically and effectively utilized than the PC on the Internet, and the utilization result can be easily returned to the user.

  FIG. 17 is an explanatory diagram showing an example of surplus CPU power utilization processing of the computer management service network system in FIG. 1, and FIG. 18 is an explanation showing an example of management control of surplus CPU power by the computer management service network system in FIG. 19 is an explanatory diagram showing an example of task assignment processing to a surplus CPU by the computer management service network system in FIG. 1, FIG. 20 is a flowchart showing an example of task assignment processing operation by the task server in FIG. 19, and FIG. FIG. 20 is a flowchart showing an example of task assignment processing operation based on a request from an external requester of the task server in FIG.

  FIG. 17 shows an example of the result of management control of surplus CPU power by the computer management service network system (1) of this example, and the task manager 1701 before improvement detects that the CPU idle rate (System idle) is 60%. As a result of assigning the scientific and engineering calculation task to the computer device, the task manager 1702 after the improvement has detected that the CPU idle rate has been improved from 60% to 5%.

  FIG. 18 shows a layout example of a task priority setting screen in the terminal devices (2a to 2c) operated by the user. In the task priority setting screen 1801 of this example, the task for effectively utilizing the surplus CPU power hinders the use of the remote user who is the owner of the computer devices (1a to 1d) equipped with the CPU. The processing priority is changed so that it is lower than normal.

  FIG. 19 shows an example of the control operation when allocating such surplus CPU power to the calculation work. In the function (task server 1902) of the center control device (1h), the calculation from the computer 1903 outside the center is performed. Subcontracting work (JOB), assigning calculation processing to computer devices (center management personal PCs) 1901a to 1901c with sufficient CPU power, collecting and aggregating each calculation result, to the requesting computer 1903 outside the center The result is returned, and charging is performed according to the usage amount of each CPU power.

  In the computer centralized operation center system (1), the fee obtained from the off-center computer 1903 as the request source is applied to the center operating cost, and the monthly monthly usage fee for each computer device (center management personal PC) 1901a-1901c. Return to the remote user by pulling down.

  A processing operation example of the task server 1902 will be described with reference to FIG. When the task server 1902 receives a JOB request from a computer 1903 outside the center (step S2001), the task server 1902 divides the JOB into tasks (step S2002), determines the order of each task (step S2003), and each computer apparatus to be assigned a task. Log in to the 1901a-1901c (center management personal PC) via the intra-center LAN (step S2004), execute the task (step S2005), and calculate the CPU power of each computer device 1901a-1901c (center management personal PC) (Step S2006).

  When all the tasks are completed (step S2007), each computer apparatus 1901a to 1901c (center management personal PC) is logged off (step S2008), each processing result is totaled (step S2009), and each CPU power is totaled and charged. After performing (step S2010), the calculation (JOB) result is transmitted to the requesting outside center computer 1903 and billing is performed (step S2011).

  Next, the execution of JOB in the center will be described with reference to FIG. When there is no calculation (JOB) request from outside the center, it is also possible to make a job request to the task server 1902 from the computer devices 1901a to 1901c owned by the remote user. A job that can be requested is a designated process in which a task division procedure is prepared in advance.

  When a remote user starts a job request application, a job list menu is displayed (step S2101), and the remote user selects, for example, “JOB which compresses a DV moving image shot by a video camera with MPEG2” from the job list menu. (Steps S2102 and S2103), an input file and an output file are designated, and the task server 1902 is requested to execute the job (steps S2104 and S2105).

  When the task server 1902 receives the input file (step S2106), the task is divided (step S2107), the order of each task is determined (step S2108), and each computer device (center management personal PC) subject to task assignment (1901a) To 1901c) via the intra-center LAN (step S2109), the task is executed (step S2110), the CPU power of each computer device is counted (step S2111), and all tasks are completed (step S2112). ), Log off from each computer device (step S2113), and perform output file transmission (step S2114).

  Note that the upper limit of the use of a JOB request is up to the cumulative value of the surplus CPU power provided in the past by the requesting computer apparatus, and the remaining CPU power accumulated value of the requesting computer apparatus becomes “0” during JOB execution. In the case of the failure, the task server 1902 logs in to the requester computer device, executes the task only with the CPU power of the requester computer device, and continues the job.

  Next, a high-quality reproduction operation of copyright data by the media server 5 in the computer centralized operation center system 1 in FIG. 1 will be described with reference to FIGS. The media server (5) is a device for using the copyright data existing on the shared storage device (shared disk) 1e other than the terminal devices 2a to 2c. By using the media server 5 in the computer centralized operation center system 1, the copyright data can be reproduced with higher quality than the terminal devices 2 a to 2 c, and there are the following merits.

  (1) Since each copyright data is stored in the shared storage device (shared disk) 1e, there is no need to store media such as CD / DVD at home or exchange media during playback. Is possible. In order to increase the commercially available content on the shared storage device (shared disk) that can be used by the user, it is performed by “purchasing” a license permitting download / playback from the center side.

  (2) Data recorded on a fixed medium such as a CD / DVD has a high risk of being released with the passage of time even if strong copy protection protection is applied. The copyright data distributed to 5 can change the data format encryption method at any time, and the decoding / playback program on the media server 5 can be updated from the center via the network, so that dynamic copyright protection measures can be taken. .

  (3) The recording of terrestrial / BS digital TV broadcasting has a “light at once” limitation, and the current hard disk recording device has a physical upper limit of the recording capacity, but on the shared storage device (shared disk) 1e. If the data is recorded on the media server 5, there is no upper limit of the recording capacity, and the media server 5 can be downloaded and played back at any time.

  22 is an explanatory diagram showing an example of data distribution processing operation of the computer management service network system in FIG. 1, FIG. 23 is a block diagram showing a configuration example of the media server in FIG. 1, and FIG. 24 is a media in FIG. It is a flowchart which shows the processing operation example of a server.

  First, the usage form of the media server will be described with reference to FIG. In FIG. 22, 2201 is a computer centralized operation center system, 2202 is a shared storage device (shared disk), 2203 is a file server 2203 as a function of the disk management device, 2204 is a router (modem), 2205 is a media server, Reference numeral 2206 denotes an HDTV, and 2207 denotes various AV devices.

  When using copyright data managed by the center on the shared storage device (shared disk) 2202 from the terminal device, the service obtained by the remote user can be obtained from a computer device owned by the computer centralized operation center system 2201. PC screen information and audio information provided in real time.

  However, with only the provision by the real-time method, those that require transfer of large-capacity data such as moving picture information on the HDTV 2206 are limited by the speed of the network line and cannot maintain the reproduction quality as it is. In order to realize high-quality data reproduction, it is necessary to once download and store data on the remote user side. As a download destination, not the terminal device (remote control terminal PC) that is likely to release the copyright protection function of the downloaded digital data by a software program, but the media server 2205 that is hardware dedicated to reproduction is used.

  As shown in FIG. 23, the media server 2205 of this example includes a semiconductor substrate as a small-capacity volatile storage device, a main board 2301 equipped with a GPU and other video / audio playback decoder function, and a large-capacity nonvolatile storage device. A hard disk 2302, a LAN board 2303, a DC converter 2304, and the like are included.

  The media server 2205 having such a configuration temporarily stores (caches) the copyright data downloaded from the shared storage device (shared disk) 2202 of the computer centralized operation center system 2201, and then installs the HDTV 2206 installed at home or the like. Or the various AV devices 2207 and the like. At this time, in order to prevent illegal copying of the copyright data, the file server 2203 (disk management device) stores the data to be transmitted in advance at predetermined intervals. The data is divided into a plurality of partial data having a predetermined amount of data and the remaining data, and the remaining data is collectively transmitted to the media server 2205. With respect to the plurality of partial data, each of the remaining data in the media server 2205 is transmitted. Divide and send along with data playback.

  In the media server 2205, the remaining data is stored in the hard disk 2302 that is a large-capacity nonvolatile storage device, and the partial data is stored in the semiconductor memory on the main board 2301. Note that the copyright data is reproduced by a decoding device (decoder) for reproducing moving images / sounds provided on the main board 2301. Also, a LAN cable is used for the interface to the router 2204, and an AV output terminal, an optical audio output terminal, and a D4 terminal are used for the interface to the HDTV 2206 and various AV devices 2207.

  Hereinafter, an example of the processing operation of the media server 2205 will be described with reference to FIG. The media server 2205 downloads and displays a list of reproducible possessed licenses from the shared storage device (shared disk) 2202 of the computer centralized operation center system 2201 before reproducing the copyright data (steps S2401 and S2402). The user designates reproduction of copyright data by selecting a menu from this list (step S2403).

  After the menu selection is finished, the playback data ("remaining data" with some partial data removed so that it cannot be played alone) is downloaded from the shared storage device (shared disk) 2202 and recorded in the hard disk (nonvolatile storage device) 2302 (Step S2404). After the playback data has been downloaded, the system waits until a playback start instruction is issued.

  If there is an instruction to start reproduction, partial data (reproduction control data) is downloaded from the shared storage device (shared disk) 2202 and recorded in the semiconductor memory (volatile storage device) on the main board (step S2405). A portion that can be reproduced by the partial data (reproduction control data) recorded in the semiconductor memory and the reproduction data recorded in the hard disk (nonvolatile storage device) 2302 is reproduced (step S2406).

  During this reproduction, partial data (reproduction control data) is downloaded from the shared storage device (shared disk) 2202 and recorded in the semiconductor memory (volatile storage device) at regular intervals, and the media server 2205 performs reproduction processing. Is performed with reference to this partial data (reproduction control data) from start to finish.

  In this way, partial data (reproduction control data) can be downloaded in a divided manner at a certain time interval as required, or by using a volatile storage device (semiconductor memory) as a download destination for partial data (reproduction control data). It is possible to prevent all reproduction information from being stored in the volatile storage device (hard disk 2302), thereby preventing illegal copying of copyright data due to data dumping from the nonvolatile storage device (hard disk 2302).

  As described above with reference to FIGS. 1 to 24, in this example, a plurality of computer devices 1a to 1d are collectively installed in a centralized operation center, not in their respective use locations, and each computer is installed on the center side. In addition to maintenance management of the devices 1a to 1d, allocation of the recording area of the shared storage device (shared disk) 1e, provision of commercially available data via the shared storage device (shared disk) 1e, and surplus of each computer device 1a to 1d Use the CPU power for other purposes. The user operates his / her terminal devices 2a to 2c (for example, a notebook PC), the cellular phone 7, and the like to connect his / her own computer devices (1a to 1d) installed in the computer central operation center via a network such as the Internet. Remote control. Further, commercially available video / music data is read from the shared storage device (shared disk) 1e and distributed to the reproduction-only media server 5 prepared by the user.

  Thus, in this example, on the center side, in addition to the collective maintenance management of the computer devices 1a to 1d, the distribution of the shared storage device (shared disk) 1e, the commercial data via the shared storage device (shared disk) 1e, It is possible to provide and divert the surplus CPU power of each of the computer devices 1a to 1d to other uses, and each user is concerned with maintenance and management while maintaining the merit of personally using the functions of the PC, for example. In addition to reducing the burden on individuals, it is possible to take advantage of the benefits that can be realized through centralized management (reuse of surplus CPU power for other uses, sharing of hard disk recording data). It is possible to eliminate the uneconomical effect of the PC that the utilization rate of the capacity is low. Furthermore, on the user side, by downloading commercially available video / music data from a shared storage device (shared disk) to a prepared media server, high-quality playback is possible via HDTV or the like.

  Further, the user can use the center PC set for himself / herself from any PC at work or travel destination, and the necessity of carrying his / her mobile PC is reduced. Further, the center PC can be used as an execution environment for batch-type processing with a high processing load such as TV broadcast PC recording and video camera video encoding, and can be used as a personal second PC. Further, the center PC can be used for data backup. In addition, the center PC can be used as a server that is always energized and operated. For example, a large-capacity file server (in this case, an additional dedicated disk) or an application server for small and medium-sized corporations (commercial services such as online shops) Service), or as an online game server hosted by an individual.

  Furthermore, by using the Internet network for remote operation of the center PC from the remote control terminal PC, it is possible to use personal computers and personal data maintained and managed anywhere in the world as long as there is a remote control terminal PC. it can. In addition, data loss due to theft, loss, or physical damage in a conventional mobile PC can be suppressed.

  Further, by centrally managing personally owned PCs at the center, it is not necessary to place the hardware to be used at home (workplace), thus eliminating the need for a PC installation location, securing a large-capacity power supply, and cooling fan noise measures. Also, the latest or special hardware can be used without hardware expertise. In other words, initial setting of PC and replacement of parts are performed on the center side. In addition, it becomes easy to request a repair when a hardware failure occurs and to prepare a substitute PC. That is, the PC board is replaced on the center side. In addition, data can be backed up safely, easily and reliably, so data maintenance is easy. That is, the shared disk is maintained on the center side, and the dedicated disk is backed up via the shared disk.

  In addition, this invention is not limited to the example demonstrated using FIGS. 1-24, In the range which does not deviate from the summary, various changes are possible. For example, in this example, terminal devices 2a to 2c such as notebook PCs or a mobile phone 7 are used as the terminal device at hand that is operated by the user. For example, by operating a PDA (not shown) or the like. The local computer apparatus (1a to 1d) installed in the computer centralized operation center system 1 is remotely operated via the network, and the shared storage device 1e is connected to the media server 5 which is a reproduction-only device prepared on the user side. Commercially available video / music data may be downloaded from HDTV 4a and various AV devices 4b.

  Also, the computer configuration example of this example may be a computer configuration without a keyboard or optical disk drive. In this example, an optical disk is used as a recording medium, but an FD (Flexible Disk) or the like may be used as a recording medium. As for the program installation, the program may be downloaded and installed via a network via a communication device.
