It is a schematic diagram of the channel allocation system 2 by the 2nd Embodiment of this invention.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, a channel allocation system 1 according to the first embodiment of the present invention includes a server 10 (corresponding to a channel allocation device of the present invention) and a mobile phone 20 (corresponding to a viewing terminal of the present invention). Composed. In FIG. 1, the number of mobile phones 20 is one, but actually there are a plurality of mobile phones 20 (the same applies to other drawings).

  The cellular phone 20 receives each channel transmitted through each transmission path of the plurality of transmission paths. Specifically, the mobile phone 20 includes a channel transmitted by a broadcast transmission path (indicated as “broadcast wave” in FIG. 1) by the broadcast facility 30 and a communication transmission path by the communication facility 40 (see FIG. 1). 1, the channel transmitted by “communication wave” is received. In addition, the mobile phone 20 stores a viewing record (denoted as “viewing log” in FIG. 1) of each channel. In addition, the mobile phone 20 transmits the viewing record to the server 10 (indicated as “upload” in FIG. 1). The mobile phone 20 may directly transmit the viewing record to the server 10 or may transmit the viewing record to the server 10 via another device.

  The server 10 acquires a viewing record stored in the mobile phone 20. The server 10 may acquire the viewing record directly from the mobile phone 20 or may acquire the viewing record via another device. The server 10 calculates a viewing rank (indicated as “popular ranking” in FIG. 1) based on the viewing record, and assigns a channel to be transmitted to each transmission path based on the viewing rank. Specifically, the server 10 assigns a broadcast transmission path to a channel whose viewing order is equal to or higher than a predetermined order, and assigns a communication transmission path to a channel whose viewing order is lower than the predetermined order. The predetermined order is an order according to the number of channels that can be allocated to the transmission line for broadcasting. That is, when the total number of channels received by the mobile phone 20 is T (T is a natural number) and the number of channels that can be allocated to the transmission line for broadcasting is N (N is a natural number less than T), the server 10 Broadcast transmission paths are assigned to the top N channels that are ranked N or more (1st,..., Nth), and the viewing order is less than N (N + 1,..., T). A transmission line for communication is assigned to a certain lower (TN) channel. In the example of FIG. 1 (T = 5, N = 3), the server 10 has the top three channels (channel 2, channel 3, channel) whose viewing order is third or higher (first, second, third). Broadcast transmission paths are allocated to 1), and communication transmission paths are allocated to the lower two channels (channel 4 and channel 5) whose viewing order is less than 3rd (4th and 5th).

  The functions of the mobile phone 20 and the server 10 will be further described with reference to FIG. The cellular phone 20 includes a viewing record storage unit 200, a program receiving unit 210, and a viewing record output unit 220 as a configuration according to the present invention. The server 10 includes a viewing record storage unit 100, a viewing record acquisition unit 110, a viewing order calculation unit 120, and a channel allocation unit 130 as a configuration according to the present invention.

  The program receiving unit 210 of the mobile phone 20 receives a channel program transmitted through a broadcast transmission path and a channel program transmitted through a communication transmission path. For example, when the program receiving unit 210 acquires identification information (hereinafter referred to as “channel ID”) for identifying a channel selected by the user from an input receiving unit (not shown) that receives input from the user, The program of the channel is received using the associated transmission line (either the transmission line for broadcasting or the transmission line for communication).

  The viewing record storage unit 200 of the mobile phone 20 stores the reception history of each channel by the program receiving unit 210 as a viewing record. For example, the viewing record storage unit 200 stores the viewing start date and time and the viewing end date and time for each channel, as shown in FIG. Further, for example, as shown in FIG. 3B, the viewing record storage unit 200 may store a channel (viewing channel) viewed in association with the viewing start date and time and the viewing end date and time.

  The viewing record output unit 220 of the mobile phone 20 outputs (transmits) the viewing record stored in the viewing record storage unit 200 to the server 10. For example, when the viewing record output unit 220 communicates with the server 10, the viewing record output unit 220 determines whether or not a viewing record of a predetermined amount or more is stored in the viewing record storage unit 200, and the viewing record of a predetermined amount or more is stored. If it is determined, the viewing record is output to the server 10. Further, for example, in addition to or instead of the above case, the viewing record output unit 220 determines whether or not a predetermined time has elapsed since the transmission of the previous viewing record when communicating with the server 10, and sets the predetermined time. The viewing record may be output to the server 10 when it is determined that the time has elapsed. Further, as shown in FIG. 3C, the viewing record output unit 220 totals the viewing records stored in the viewing record storage unit 200 (for example, totals the viewing time for each channel), The viewing record may be output to the server 10.

  The viewing record acquisition unit 110 of the server 10 acquires a viewing record from the mobile phone 20. Note that the viewing record acquisition unit 110 acquires viewing records from the plurality of mobile phones 20. The viewing record storage unit 100 of the server 10 stores the viewing record acquired by the viewing record acquisition unit 110.

  The viewing order calculation unit 120 of the server 10 calculates the viewing order of each channel based on the viewing records stored in the viewing record storage unit 100. That is, the viewing order calculating unit 120 calculates the total viewing time for each channel by the plurality of mobile phones 20, and determines the viewing order of each channel in the order of the longest total viewing time. The viewing order calculation unit 120 supplies the viewing order calculation result to the channel assignment unit 130. FIG. 4A shows an example of the viewing rank calculation result. In the example of FIG. 4A, the viewing rank calculation unit 120 determines that the viewing rank “1st” is channel 2, the viewing rank “2nd” is channel 3, the viewing rank “3rd” is channel 1, and the viewing rank “4”. The “rank” is a calculation result calculated that the channel 4 and the viewing rank “fifth” is the channel 5.

  The channel assignment unit 130 of the server 10 assigns a channel to each transmission path based on the viewing order calculated by the viewing order calculation unit 120. Specifically, the channel assignment unit 130 assigns a broadcast transmission path to a channel whose viewing order is equal to or higher than a predetermined order, and assigns a communication transmission path to a channel whose viewing order is lower than the predetermined order. The channel allocation unit 130 outputs (transmits) the allocation result to the broadcasting facility 30 and the communication facility 40. FIG. 4B is an example of a channel assignment result. The example of FIG. 4B is an assignment result in which the channel assignment unit 130 assigns channels 1, 2, and 3 to the broadcast transmission path and assigns channels 4 and 5 to the communication transmission path.

  The broadcasting facility 30 that has acquired the allocation result from the channel allocation unit 130 of the server 10 transmits the corresponding channel through the broadcast transmission path based on the allocation result. For example, when the broadcast facility 30 acquires the allocation result shown in FIG. 4B, the broadcast facility 30 transmits the channels 2, 3, and 1 through the broadcast transmission path. Further, the communication facility 40 that has acquired the allocation result from the channel allocation unit 130 of the server 10 transmits the corresponding channel through the communication transmission path based on the allocation result. For example, when the communication facility 40 acquires the allocation result shown in FIG. 4B, the communication facility 40 transmits the channels 4 and 5 through the communication transmission path. Note that the broadcasting facility 30 and the communication facility 40 obtain program information for each channel from a content storage device (not shown). The server 10 may be a content storage device.

  Next, the operation of the channel assignment system 1 will be described using FIGS. 5 (a), 5 (b), and 5 (c). 5A is a flowchart showing the operation when the mobile phone 20 stores the viewing record, FIG. 5B is a flowchart showing the operation when the mobile phone 20 outputs the viewing memory, and FIG. 4 is a flowchart illustrating an operation when a server 10 assigns a channel. Note that FIG. 5D will be described later.

  The flowchart shown in FIG. 5A starts when the program receiving unit 210 acquires a channel ID from an input receiving unit (not shown). In addition, an input reception part (not shown) shall supply the channel ID of the said program to the program receiving part 210, when the input of a program selection is received from a user via a program schedule. In addition, the mobile phone 20 receives a program guide from the outside (for example, the server 10) as appropriate. Further, it is assumed that the program table stores associations between programs, channels, and transmission paths.

  The program receiving unit 210 that has acquired the channel ID stores the viewing record (viewing start date and time) in the viewing record storage unit 200 in association with the channel ID (step S100), and receives the program (step S110). Subsequently, the program receiving unit 210 determines whether or not the channel has been changed (step S120). For example, the program receiving unit 210 determines that the channel has been changed when a new channel ID (changed channel ID) is acquired from an input receiving unit (not shown).

  When determining that the channel has been changed (step S120: Yes), the program receiving unit 210 stores the viewing record (viewing end date and time) in the viewing record storage unit 200 in association with the channel ID before the change (step S130). Returning to step S100, the viewing record (viewing start date and time) is stored in the viewing record storage unit 200 in association with the changed channel ID (step S100).

  On the other hand, when determining that the channel has not been changed (step S120: No), the program receiving unit 210 determines whether or not to end the viewing (step S140). For example, the program receiving unit 210 determines to end viewing when receiving a notification of viewing end from an input receiving unit (not shown). When the program receiving unit 210 determines not to end the viewing (step S140: No), the program receiving unit 210 returns to step S110. On the other hand, when the program receiving unit 210 determines to end the viewing (step S140: Yes), it stores the viewing record (viewing end date and time) in the viewing record storage unit 200 in association with the current channel ID (step S150). Then, the program reception ends (step S160). Then, the flowchart shown in FIG.

  The flowchart shown in FIG. 5B starts, for example, when the power supply of the mobile phone 20 is introduced. The viewing record output unit 220 determines whether an opportunity to communicate with the server 10 has occurred (step S200). For example, the viewing record output unit 220 determines that an opportunity to communicate with the server 10 has occurred when a notification to communicate with the server 10 is acquired from an input reception unit (not shown).

  When the viewing record output unit 220 determines that an opportunity to communicate with the server 10 has occurred (step S200: Yes), the viewing record output unit 220 determines whether or not a predetermined amount or more of the viewing record is stored in the viewing record storage unit 200 ( Step S210). When the viewing record output unit 220 determines that a predetermined amount or more of viewing records are not stored (step S210: No), the viewing record output unit 220 determines whether a predetermined time has elapsed since the transmission of the previous viewing record (step S210). S220).

  The viewing record output unit 220 determines that a predetermined amount or more of the viewing record is stored (step S210: Yes) or determines that a predetermined time has elapsed since the previous transmission of the viewing record (step S220). : Yes), the viewing record is output to the server 10 (step S230). When the viewing record output unit 220 outputs the viewing record to the server 10, the server 10 (viewing record acquisition unit 110) acquires the viewing record and stores it in the viewing record storage unit 100.

  The viewing record output unit 220 determines that the opportunity to communicate with the server 10 has not occurred (step S200: No), determines that the predetermined time has not elapsed (step S220: No), or step Subsequent to S230, it is determined whether or not the power is turned off (step S240). For example, the viewing record output unit 220 determines that the power is turned off when a power-off notification is acquired from an input reception unit (not shown). When the viewing record output unit 220 determines that the power is not turned off (step S240: No), the viewing record output unit 220 returns to step S200. On the other hand, when the viewing record output unit 220 determines that the power is turned off (step S240: Yes), the flowchart shown in FIG. 5B ends. Note that the mobile phone 20 may have a viewing record output mode in which viewing records are output under a predetermined condition, and a viewing record non-output mode in which viewing records are not output. When the mobile phone 20 has a viewing record output mode and a viewing record non-output mode, the flowchart shown in FIG. 5B starts when the user sets the viewing record output mode, and the user sets the viewing record non-output mode. Sometimes it ends.

  The flowchart illustrated in FIG. 5C starts, for example, when an instruction from the administrator of the server 10, a predetermined time, or a viewing record of a predetermined amount or more is stored in the viewing record storage unit 100. The viewing order calculation unit 120 calculates the viewing order of each channel based on the viewing record stored in the viewing record storage unit 100 (step S300). The viewing order calculation unit 120 supplies the viewing order calculation result to the channel assignment unit 130. Based on the calculation result of the viewing order, the channel assigning unit 130 assigns the channel whose viewing order is equal to or higher than the predetermined order to the broadcast transmission path (step S310), and sets the channel whose viewing order is lower than the predetermined order. A transmission line for communication is assigned (step S320). The channel allocation unit 130 outputs the allocation result to the broadcasting facility 30 and the communication facility 40. Then, the flowchart shown in FIG.

  As described above, according to the channel assignment system 1, each channel can be rationally accommodated in each transmission path of the broadcast service. Therefore, the broadcasting service becomes efficient. Further, since the correspondence between programs, channels, and transmission paths is stored in the program guide, the user of the mobile phone 20 does not need to be aware of which transmission path the program to be viewed is transmitted. In addition, since the recorded information is output to the server 10 when an opportunity to communicate with the server 10 occurs, no burden is imposed on the user of the mobile phone 20.

(Second Embodiment)
Hereinafter, a second embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIG. 6, the channel allocation system 2 according to the second embodiment of the present invention includes a server 11 (corresponding to the channel allocation device of the present invention) and a mobile phone 21 (corresponding to the viewing terminal of the present invention). Composed.

  The mobile phone 21 receives each channel transmitted through each transmission path of the plurality of transmission paths. Specifically, the mobile phone 21 uses a channel transmitted by the broadcasting facility 31 through a transmission path for national broadcasting (indicated as “national broadcasting wave” in FIG. 6), a transmission for regional broadcasting by the broadcasting facility 31. The channel transmitted by the channel (indicated as “local broadcast wave” in FIG. 6) and the channel transmitted by the communication channel (indicated by “communication wave” in FIG. 6) by the communication facility 40 are received. . In addition, the mobile phone 21 stores a viewing record (denoted as “viewing log” in FIG. 6) of each channel. In addition, the mobile phone 21 transmits the viewing record together with the area information indicating the viewing area to the server 11 (indicated as “upload” in FIG. 1). The mobile phone 21 may directly transmit the area information and the viewing record to the server 11 or may transmit the area information and the viewing record to the server 11 via another device.

  The server 11 acquires area information and viewing records. The server 11 may directly acquire the area information and the viewing record from the mobile phone 21 or may acquire the area information and the viewing record through another device. The server 11 calculates the national viewing rank (indicated as “national popular ranking” in FIG. 6) and the regional ranking (indicated as “local popular ranking” in FIG. 6) based on the regional information and the viewing record, A channel to be transmitted is assigned to each transmission path based on the viewing order. Specifically, the server 11 assigns a transmission channel for national broadcasting to a channel whose national viewing rank is equal to or higher than the first predetermined rank, and the national viewing rank is less than the first predetermined rank and the local viewing rank. A channel for regional broadcasting is assigned to a channel whose rank is equal to or higher than the second predetermined rank, the national viewing rank is less than the first predetermined rank, and the local viewing rank is less than the second predetermined rank. Assign a transmission line for communication to the channel. The first predetermined order is an order according to the number of channels that can be allocated to the transmission path for national broadcasting. The second predetermined order is an order according to the number of channels that can be allocated to the transmission path for regional broadcasting. That is, the total number of channels received by the mobile phone 21 is T (T is a natural number), and the number of channels that can be allocated to the transmission path for national broadcasting is Nz (Nz is a natural number less than T, where T> Nz + Nt). When the number of channels that can be allocated to the transmission line for broadcasting is Nt (Nt is a natural number less than T, where T> Nz + Nt), the server 11 has a national viewing rank of Nz or higher (1st,... , Nz rank), a transmission channel for national broadcasting is assigned to the channel, the national viewing rank is less than Nz rank (Nz + 1 rank,..., T rank), and the local viewing rank is Nt rank (1st rank, .., Nt) is assigned to a channel for regional broadcasting, the national viewing order is less than Nz (Nz + 1,..., T), and the local viewing order is less than Nt. Nt + 1, ... Assigning a transmission path for communication channel is a position). In the example of FIG. 6 (T = 5, Nz = 2, Nt = 1), the server 11 is for national broadcasting on channels (channel 5 and channel 3) whose national viewing rank is 2nd or higher (1st and 2nd). For the local broadcasting channel (channel 2) with a national viewing rank of less than 2nd (3rd, 4th, 5th) and a local viewing rank of 1st or higher (1st) Channels that are assigned a transmission channel and have a national viewing rank of less than 2nd (3rd, 4th, 5th) and a local viewing rank of less than 1st (2nd, 3rd, 4th, 5th) ( Channels 1 and 4) are assigned transmission paths for communication. Note that the first predetermined order and the second predetermined order may be the same.

  The functions of the mobile phone 21 and the server 11 will be further described with reference to FIG. The cellular phone 21 includes a viewing record storage unit 200, a program receiving unit 211, and a viewing record output unit 221 as a configuration according to the present invention. The server 11 includes a viewing record storage unit 101, a viewing record acquisition unit 111, a viewing order calculation unit 121, and a channel allocation unit 131 as a configuration according to the present invention.

  The program receiving unit 211 of the mobile phone 21 includes a channel program transmitted by a national broadcasting transmission path, a channel program transmitted by a regional broadcasting transmission path, and a channel transmitted by a communication transmission path. Receive the program. When the program receiving unit 211 obtains a channel ID from an input receiving unit (not shown), the program receiving unit 211 transmits a transmission path associated with the channel (a transmission path for national broadcasting, a transmission path for regional broadcasting, or a communication channel). The program of the channel is received using any one of the transmission paths.

  Similar to the viewing record storage unit 200 of the mobile phone 20 according to the first embodiment, the viewing record storage unit 201 of the mobile phone 21 stores the reception history of each channel as a viewing record.

  The viewing record output unit 221 of the mobile phone 21 outputs (transmits) the viewing record stored in the viewing record storage unit 200 together with the area information to the server 11. The mobile phone 21 stores in advance predetermined (fixed) area information (for example, where the mobile phone 21 is contracted), and the viewing record output unit 221 outputs the predetermined area information to the server 11. Also good. Further, the mobile phone 21 may output position information when outputting the viewing record to the server 11 instead of the predetermined area information. The manner in which the viewing record output unit 221 outputs the viewing record to the server 11 is the same as that of the viewing record output unit 220 of the mobile phone 20 according to the first embodiment.

  The viewing record acquisition unit 111 of the server 11 acquires area information and viewing records from the mobile phone 21. The viewing record acquisition unit 111 acquires area information and viewing records from the plurality of mobile phones 21. The viewing record storage unit 101 of the server 11 stores the area information and the viewing record acquired by the viewing record acquisition unit 111.

  The viewing rank calculation unit 121 of the server 11 calculates the national viewing rank and the regional viewing rank of each channel based on the regional information and the viewing record stored in the viewing record storage unit 101. That is, the viewing rank calculation unit 121 calculates the total viewing time for each region and channel by the plurality of mobile phones 21 and calculates the national viewing rank and the regional viewing rank for each channel. The viewing order calculation unit 121 supplies the viewing order calculation result to the channel assignment unit 131. In addition, FIG.4 (c) is an example of the calculation result of a national viewing ranking and a regional viewing ranking. In the example of FIG. 4C, the viewing ranking calculation unit 121 determines that the national viewing ranking “1st” is channel 5, the national viewing ranking “2nd” is channel 3, and the national viewing ranking “3rd ranking” is channel 1, nationwide. Viewing order "4th" is channel 4, national viewing order "5th" is channel 2, regional viewing order "1st" is channel 2, regional viewing order "2nd" is channel 3, regional viewing order "3rd" Is a calculation result that channel 1 is calculated, channel viewing order "4th" is channel 4, and local viewing order "5th" is channel 5.

  The channel allocating unit 131 of the server 11 allocates a transmission channel for national broadcasting to a channel whose national viewing order is equal to or higher than the first predetermined order, and the national viewing order is less than the first predetermined order and regional viewing. A channel for regional broadcasting is assigned to a channel whose rank is equal to or higher than the second predetermined rank, the national viewing rank is less than the first predetermined rank, and the local viewing rank is less than the second predetermined rank. Assign a transmission line for communication to the channel. The channel allocation unit 131 outputs (transmits) the allocation result to the broadcasting facility 31 and the communication facility 40. FIG. 4D is an example of the channel assignment result. In the example of FIG. 4D, the channel allocation unit 131 allocates channels 5 and 3 to the national broadcasting transmission path, allocates channel 2 to the regional broadcasting transmission path, and sets channel 1 to the communication transmission path. This is the assignment result of assigning 4.

  Note that the broadcasting equipment 31 that has acquired the allocation result from the channel allocation unit 131 of the server 11 transmits the corresponding channel through the transmission path for national broadcasting or regional broadcasting based on the allocation result. For example, when the allocation facility shown in FIG. 4D is acquired, the broadcasting facility 31 transmits the channels 5 and 3 through the transmission channel for national broadcasting and transmits the channel 2 through the transmission channel for regional broadcasting.

  Next, the operation at the time of channel assignment by the server 11 will be described with reference to FIG. The flowchart shown in FIG. 5D starts when, for example, an instruction from the administrator of the server 11, a predetermined time, or a viewing record of a predetermined amount or more is stored in the viewing record storage unit 101. The viewing order calculation unit 121 calculates the national viewing order based on the regional information and the viewing record stored in the viewing record storage unit 101 (step S400), and calculates the local viewing order (step S405). The viewing order calculation unit 121 supplies the calculation results of the national viewing order and the regional viewing order to the channel assignment unit 131. The channel allocation unit 131 allocates a transmission channel for national broadcasting to a channel whose national viewing order is equal to or higher than the first predetermined order based on the calculation results of the national viewing order and the regional viewing order (step S410). A transmission channel for regional broadcasting is assigned to a channel whose rank is less than the first predetermined rank and the regional viewing rank is equal to or higher than the second predetermined rank (step S415), and the national viewing rank is the first predetermined rank. A communication transmission path is assigned to a channel that is less than the rank and has a local viewing rank less than the second predetermined rank (step S420). The channel assignment unit 131 outputs the assignment result to the broadcasting equipment 31 and the communication equipment 40. Then, the flowchart shown in FIG.

  As described above, according to the channel assignment system 2, each channel can be reasonably accommodated in each transmission path of the national broadcasting service and the regional broadcasting service. Therefore, the broadcasting service becomes efficient. In addition, since the correspondence between programs, channels, and transmission paths is stored in the program guide, the user of the mobile phone 21 does not need to be aware of which transmission path the program to be viewed is transmitted. In addition, since the recorded information is output to the server 11 when an opportunity to communicate with the server 11 occurs, no burden is imposed on the user of the mobile phone 21.

  In the second embodiment, when the server 11 stores area information in advance in association with terminal identification information for identifying the mobile phone 21, the mobile phone 21 uses the terminal identification information instead of the area information. At the same time, the viewing record may be output to the server 11. Examples of the terminal identification information include a telephone number, an e-mail address, and identification information (for example, a registration number for the channel allocation system 2) separately given to the mobile phone 21 in the channel allocation system 2.

  Further, as the plurality of transmission lines, an example in which the transmission line for broadcasting and the transmission line for communication are divided in the first embodiment will be described, and in the second embodiment, the transmission line for broadcasting is further arranged nationwide. Although an example of dividing into broadcasting and regional broadcasting has been described, the division of a plurality of transmission paths is not limited to the above example. For example, a satellite broadcast transmission line and a terrestrial transmission line may be divided, or a pay broadcast transmission line and a free broadcast (non-paid broadcast) transmission line may be divided. Good.

  Note that the mobile phone 20 in the first embodiment is an example of a viewing terminal. The viewing terminal may be, for example, a notebook computer, a game device, a musical sound playback device, a car navigation system main body, or the like. The same applies to the mobile phone 21 in the second embodiment.

  Note that a program for executing each process of the channel assignment systems 1 and 2 according to the embodiment of the present invention is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read by the computer system. By executing, the above-described various processes related to the channel assignment systems 1 and 2 according to the embodiment of the present invention may be performed. Here, the “computer system” may include an OS and hardware such as peripheral devices. Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used. The “computer-readable recording medium” means a flexible disk, a magneto-optical disk, a ROM, a writable nonvolatile memory such as a flash memory, a portable medium such as a CD-ROM, a hard disk built in a computer system, etc. This is a storage device.

  Further, the “computer-readable recording medium” means a volatile memory (for example, DRAM (Dynamic DRAM) in a computer system that becomes a server or a client when a program is transmitted through a network such as the Internet or a communication line such as a telephone line. Random Access Memory)), etc., which hold programs for a certain period of time. The program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the “transmission medium” for transmitting the program refers to a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. The program may be for realizing a part of the functions described above. Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, and what is called a difference file (difference program) may be sufficient.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes designs and the like that do not depart from the gist of the present invention.
