Description

  The present invention relates to a data depositing apparatus, a data depositing method, and a data depositing program for depositing data on a network, and more particularly to a technique when the same data is received from a plurality of apparatuses.

  Conventionally, data owned by individuals is prepared by recording a plurality of recording media such as video tapes for programs and CD-R or DVD-RAM (Digital Versatile Disk-Random Access Memory) for other data. Accumulated in the medium. And it is necessary to manage these recording media individually.

  At present, hard disk recorders that store broadcast programs have become widespread, particularly for moving image data. With a hard disk recorder, it is possible to record video data of many programs on the hard disk, and management of video data of programs has become easy. However, even if such a device is used, if the moving image data of the stored program increases, the capacity of the hard disk is naturally insufficient.

  In order to solve this problem, a technique has been proposed in which data owned by an individual is stored in a storage area provided on a network (for example, Patent Document 1). This technology has solved the problem of insufficient hard disk capacity and eliminates the need for complicated recording medium management.

  Exemplary embodiments of a data depositing apparatus, a data depositing method, and a data depositing program according to the present invention are explained in detail below with reference to the accompanying drawings.

(First embodiment)
FIG. 1 shows a network configuration of a moving image data depositing server 100 that implements the function of the data depositing device according to the first embodiment of the present invention and a home server 110A that manages home moving image data, and a moving image data depositing server and a home. It is a block diagram which shows the structure of a server. Of course, a plurality of home servers may be connected on the network.

  The moving image data deposit server 100 shown in FIG. 1 includes a storage unit 101, a communication unit 102, a determination unit 103, an authentication unit 104, and an addition unit 105. With these configurations, the moving image data depositing server 100 determines whether or not the same moving image data exists when receiving moving image data, and receives moving image data only when the same moving image data does not exist. Is possible.

  The storage unit 101 corresponds to the data storage unit and management information storage unit of the present invention, and stores moving image data and a moving image data management table. The moving image data is assumed to be moving image data transmitted from the home server.

  FIG. 2 is a diagram showing the configuration of the moving image data management table. As shown in the figure, the moving image data management table holds an identification ID, a data storage location, and a user ID in association with each other. The identification ID is a unique identification ID for each moving image data, and in this embodiment, 'start time'-'end time'-'channel number' and recording start time, recording end time, and numerical values indicating the recorded channel are set. It shall be combined. For example, the identification ID of the video data recorded with the channel number '1' from 12:00 on July 31, 2004 to 14:00 on July 31, 2004 is 200407311200-200407311400-1. Become. The moving image data management table associates and manages the identification ID and moving image data by holding the identification ID and the storage location of the moving image data in association with each other. The server ID is an ID indicating a home server that has transmitted or tried to transmit moving image data but did not transmit because there is already the same moving image data. By storing the server ID, the identification ID, and the storage location in association with each other, it is possible to record the program and specify the home server that attempted to upload the moving image data to the moving image data depositing server 100. Further, since the moving image data and the identification ID are stored in association with each other in the moving image data management table, the management is facilitated, and the identification ID for specifying the moving image data is easily compared with the identification ID received from the home server 110A. In addition, since the identification ID and the server ID are managed in association with each other, the home server that transmitted the moving image data can be easily specified.

  In addition, even if the start time and end time are specified in minutes in the identification ID, even if it is the same program, the time specified for each user may be different, but electronic program guides currently displayed on the television, etc. It is generally considered that the same start and end times are set for the same program.

  Returning to FIG. 1, the communication unit 102 includes a notification unit 121, an identification reception unit 122, a data transmission unit 123, and a data reception unit 124, and communicates with a home server 110A connected via a public network.

The home server capable of communication may be a home server having the same configuration as the home server 110A and connected to the network.

  The identification receiving unit 122 receives, from the home server 110A, an identification ID that identifies moving image data to be deposited together with a moving image data deposit request. The identification receiving unit 122 also receives an identification ID for specifying the moving image data together with the request for returning the moving image data from the home server 110A.

  As a result of the custody request, the notifying unit 121 made a custody request depending on whether or not there is a record having the same identification ID as the ID received together with the custody request in the moving image data management table by the determination unit 103 described later. The home server 110A is notified of the request result. That is, when it is determined that there is no record having the same identification ID as the identification ID received by the determination unit 103, a notification that the moving image data is not stored is sent together with the identification ID as a request result. Further, when it is determined that there is a record having the same identification ID as the identification ID received by the determination unit 103, a notification that the moving image data is stored is notified together with the identification ID as a request result.

  The data receiving unit 124 receives the video data specified by the identification ID received at the time of the custody request from the home server 110 </ b> A after the notification unit 121 is notified that the video data is not stored, and stores it in the storage unit 101. To do. In addition, the data receiving unit 124 receives a completion notification from the home server after receiving the moving image data.

  The data transmission unit 123 transmits the moving image data to the home server 110A that has deposited the moving image data when the authentication unit 104, which will be described later, properly authenticates.

  The determination unit 103 compares the identification ID received by the communication unit 102 together with the moving image data deposit request with the identification IDs of all the records included in the moving image data management table, and determines whether there is a matching record. Then, the determination unit 103 outputs a determination result indicating whether or not a matching record exists to the notification unit 121.

  The adding unit 105 adds information corresponding to the custody request from the home server to the moving image data management table stored in the storage unit 101. After the data receiving unit 124 receives the moving image data from the home server 110A and accumulates it in the storage unit 101, the adding unit 105 identifies the received moving image data, the ID where the moving image data is accumulated, the home server The server ID indicating 110A is associated and added to the moving image data management table.

  If the determination unit 103 compares the identification ID held in the moving image data management table with the identification ID received from the home server 110A and determines that a matching record exists, the adding unit 105 matches the moving image data management table. The server ID of the home server 110A that transmitted the identification ID is added to the server ID of the record having the identification ID. In this case, the data receiving unit 124 does not receive moving image data from the home server 110A. The server ID of the home server that has not transmitted the moving image data is also added to the moving image data management table, so that the moving image is transmitted from the home server specified by the added server ID even though the moving image data is not transmitted / received. It means that you have deposited your data. After that, by referring to this video data management table and authenticating whether or not to return the video data, regardless of whether the video data is actually transmitted or not, if it is a home server that has made a custody request, the video data Can be transmitted.

  For example, the data of the second record in the moving image data management table shown in FIG. 2 is a record added to the moving image data transmitted by the home server with the server ID A0001, and is later transmitted from the home server with the server ID B0003. If the identified ID matches the identification ID of the second record, the video data is not received from the home server that becomes B0003, and the adding unit 105 confirms that B0003 has been added to the server ID of the second record. Show.

  The authentication unit 104 transmits a server ID and an identification ID held in the video data management table, and a transmission when the identification receiving unit 122 receives a video data return request from the home server 110A together with an authentication ID for specifying the server ID and video data. The requested authentication ID and server ID are compared, and if there is a record that matches the moving image data management table, it is assumed that the authentication is properly performed. When the authentication is properly performed, the data transmission unit 123 transmits the moving image data specified at the storage location of the matched record to the home server specified by the server ID. By providing the authentication unit 104, the moving image data can be transmitted only to the home server that has previously requested that the moving image data be stored.

  The moving picture data depositing server 100 of the present embodiment is an example for realizing the present invention, and the moving picture data depositing server has already deposited the moving picture data in response to a request from the home server 110A. Any configuration is possible as long as it is possible to notify the home server 110A whether or not the home server 110A can receive from the home server 110A only when it is not stored.

  The home server 110A includes a storage unit 111, a communication unit 112, a deposit determination unit 113, a moving image acquisition unit 114, a moving image deletion unit 115, a reproduction processing unit 116, an identification ID generation unit 117, and an input processing unit 118. It is composed of The home server 110 </ b> A includes these configurations, thereby enabling the moving image data depositing server 100 to deposit the moving image data stored in the storage unit 111. The home server 110A is provided in each home and stores moving image data recorded in the home.

  The storage unit 111 stores moving image data and a moving image data identification ID management table. The moving image data is recorded and accumulated by the home server 110A or a recording device installed in the home connected to the home server 110A.

  FIG. 3 is a diagram showing a configuration of the moving image data identification ID management table. As shown in the figure, the moving image data identification ID management table holds the identification ID and the file name of the moving image data in association with each other. The identification ID is a unique identification ID for each moving image data, and is an identification ID having the same generation method as the identification ID held in the moving image data management table stored in the storage unit 101 by the moving image data depositing server 100 described above. The moving image data identification ID management table associates and manages the identification ID and moving image data by holding the identification ID and the file name of the moving image data in association with each other. In addition, a record in which the file name is not registered with only the identification ID indicates moving image data in which the moving image data is deposited in the moving image data depositing server 100.

  Returning to FIG. 1, the input processing unit 118 inputs an operation from a user via a pointing device, a keyboard, or another device connected via a home network. The input processing unit 118 inputs a user's operation when the user deposits moving image data, records moving image data, or reproduces moving image data in the moving image data depositing server 100. The input processing unit 118 allows the user to request processing from the deposit determination unit 113, the moving image acquisition unit 114, and the reproduction processing unit 116, which will be described later.

  The communication unit 112 communicates with the moving image data deposit server 100 connected via a public network. The communication unit 102 transmits a custody request for moving image data together with the identification ID associated with the moving image data, and further receives a request result for the custody request together with the identification ID from the moving image data deposit server 100.

  If the deposit determination unit 113 determines that the moving image data is to be transmitted after receiving the request result, the moving image data specified by the identification ID received together with the request result is transmitted. Further, the communication unit 112 transmits a completion notification to the moving image data depositing server 100 after transmitting the moving image data.

  In addition, when the fact that the moving image data to be reproduced together with the identification ID is input from the reproduction processing unit 116 described later, the communication unit 112 transmits to the moving image data depositing server 100 that the moving image data is returned together with the identification ID. When the authentication is properly performed by the moving image data depositing server 100, the communication unit 112 receives the moving image data specified by the identification ID transmitted from the moving image data depositing server 100.

  The deposit determination unit 113 determines whether to deposit the moving image data in the moving image data deposit server 100. The deposit determination unit 113 determines that the moving image data is to be deposited when there is a request from the user to deposit the moving image data or when the storage area in the storage unit 111 that can store the moving image data decreases. When the communication unit 112 receives the request result, the deposit determination unit 113 determines whether to transmit the moving image data based on whether the same moving image data indicated in the request result is already stored. . That is, when the same moving image data is deposited, the deposit determination unit 113 determines not to transmit the moving image data. If the same moving image data is not deposited, the deposit determination unit 113 determines to transmit the moving image data.

  The moving image acquisition unit 114 records moving image data being broadcast or acquires moving image data from a recording device that records the broadcast in a home connected to a home network, and stores the moving image data in the storage unit 111.

  The identification ID generation unit 117 generates an identification ID associated with the moving image data acquired by the moving image acquisition unit 114, and adds the generated identification ID to the moving image data identification ID management table in association with the file name of the moving image data. The identification ID generated by the identification ID generation unit 117 generates an identification ID having the same configuration as the identification ID of the moving image data management table stored in the storage unit 101 of the moving image data depositing server 100 described above. '-'End time'-'Channel number' is generated by a combination of a recording start time, a recording end time and a numerical value indicating the recorded channel. When the video data depositing server 100 performs recording, the recording start time, recording end time, and recorded channel are acquired from the settings made in the own apparatus. In the case of moving image data input from another recording device, the recording start time, recording end time, and recorded channel are acquired from the other recording device.

  The moving image deletion unit 115 deletes the moving image data that the home server 110A has requested to be stored in the moving image data depositing server 100 regardless of whether the moving image data is actually transmitted to the moving image data depositing server 100 or not. At that time, the file name of the record indicating the deleted moving image data in the moving image data identification ID management table stored in the storage unit 111 is deleted. Thus, it is possible to determine whether the moving image data is stored in the storage unit or stored in the moving image data depositing server 100 by referring to the presence or absence of the file name in the moving image data identification ID management table.

  The reproduction processing unit 116 reproduces the moving image data when there is a request for reproducing the moving image data from the user. When the user selects moving image data to be reproduced from the moving image data managed in the moving image data identification ID management table, the reproduction processing unit 116 determines that the file name is input in the record of the selected moving image data. Play video data specified by file name. If no file name is input to the selected video data record, the video data return request is sent to the video data depositing server 100 via the communication unit 112 together with the identification ID held by the record and the server ID of the home server 110A. I do. Then, the reproduction processing unit 116 reproduces the moving image data transmitted from the moving image data depositing server 100 from the communication unit 112 via the storage unit 111. The display device that displays the reproduced moving image data is not particularly limited. For example, a display connected to the home server 110A or a device that can display moving image data connected to the home network is considered. It is done.

  The home server 110A enables not only the moving image data stored in the home server 110A but also the moving image data stored in the moving image data depositing server 100 to be reproduced. Accordingly, it is possible to hold reproducible moving image data that is greater than or equal to the moving image data that can be held in the storage area provided in the home server 110A. It should be noted that the time at which the moving image data is transmitted to the moving image data depositing server 100 is not limited, and the moving image data may be transmitted after the recording of the broadcast program is completed, or the broadcast program is being recorded. The transmission of moving image data may be started from.

  Next, in the moving image data deposit server 100 and the home server 110A according to the present embodiment configured as described above, after the home server 110A records the broadcast as moving image data, the moving image data deposit server 100 stores the moving image data. The processing up to deposit will be described. FIG. 4 is a flowchart showing a procedure of the above-described processing in the moving image data deposit server 100 and the home server 110A according to the present embodiment.

  First, the processing procedure of the home server 110A will be described. The moving image acquisition unit 114 of the home server 110A accumulates the moving image data obtained by recording the broadcast program or the moving image data acquired from the recording device in the storage unit 111 (step S311). Then, the identification ID generation unit 611 generates an identification ID for specifying the moving image data, associates the identification ID with the file name of the moving image data, and adds them to the moving image data identification ID management table (step S312). Next, the deposit judging unit 113 judges whether to record the recorded moving image data in the moving image data depositing server 100 based on the user request or the storage area of the storage unit 111 (step S313). If it is determined that the moving image data deposit server 100 does not deposit the moving image data (step S313: No), the processing is terminated without performing any particular processing.

  When the deposit determination unit 113 determines to deposit the moving image data (step S313: Yes), the communication unit 112 transmits a moving image data deposit request together with the moving image data identification ID to the moving image data deposit server 100 (step S314).

  And the communication part 112 receives the request | requirement result with respect to a custody request | requirement from the moving image data deposit server 100 (step S315). The deposit determination unit 113 determines whether to transmit moving image data to the moving image data depositing server 100 based on whether moving image data having the same request result has already been deposited (step S316).

  If the deposit determination unit 113 determines that the moving image data having the same request result has not been deposited and determines that the moving image data is to be transmitted (step S316: No), the communication unit 112 uses the identification ID received together with the request result. The specified moving image data is transmitted to the moving image data depositing server 100 (step S317). Then, after the transmission of the moving image data is completed, the communication unit 112 transmits a transmission completion notification to the moving image data depositing server 100 (step S318).

  Then, after the communication unit 112 transmits a transmission completion notification (step S318), or after the deposit determination unit 113 determines not to transmit moving image data from the request result (step S316: Yes), the moving image deletion unit 115 transmits The video data specified by the identification ID received together with the requested video data or the request result is deleted, and the file name is assigned to the record corresponding to the video data deleted in the video data identification ID management table stored in the storage unit 111. It deletes and complete | finishes (step S319).

  Next, the processing procedure of the moving image data depositing server 100 will be described. The identification receiving unit 122 receives the moving image data storage request together with the identification ID from the home server 110A (step S301). Then, the determination unit 103 compares the identification ID transmitted from the home server 110A with the identification ID included in the moving image data management table stored in the storage unit 101, and whether there is a record having an identification ID that matches the identification ID. It is determined whether or not (step S302). When the determination unit 103 determines that there is a matching record and the same moving image data already exists (step S302: Yes), the notification unit 121 identifies the request result that the same moving image data is deposited in the home server 110A. It transmits with ID (step S303). The adding unit 105 adds the server ID of the home server 110A to the server ID of the record having the received identification ID, and the process ends (step S304).

  When the determination unit 103 determines that there is no matching record and there is no same moving image data (step S302: No), the notification unit 121 identifies a request result that the same moving image data is not stored in the home server 110A. It transmits with ID (step S305). Then, the data receiving unit 124 receives moving image data from the home server 110A (step S306). Next, the data receiving unit 124 accumulates the received moving image data (step S307). Then, when the data receiving unit 124 receives the transmission completion notification from the home server 110A, it is assumed that the reception of the moving image data is completed (step S308), and the adding unit 105 stores the received identification ID and the moving image data in the received ID. A record in which the location is associated with the server ID of the home server 110A is added to the moving image data management table, and the process ends (step S309).

  In the above-described processing procedure, the processing procedure performed between the video data depositing server 100 and the home server 110A has been described. However, the home server that transfers the video data depositing server 100 and the video data is limited to the home server 110A. Instead, any home server connected to the moving image data depositing server 100 via a public network and having the same configuration as the home server 110A may be used.

  The above-described processing procedure is an example of a processing procedure performed until the moving image data deposited between the moving image data depositing server 100 and the home server is transmitted, and the moving image between the moving image data depositing server 100 and the home server is illustrated. When depositing the data, any processing procedure may be used as long as the processing procedure is such that transmission is not performed when there is the same moving image data but transmission is possible when there is no same moving image data.

  FIG. 5 is a diagram illustrating a hardware configuration of a PC that executes a program for realizing the function of the moving image data depositing server 100. The moving image data deposit server 100 according to the present embodiment includes a control device such as a CPU (Central Processing Unit) 901, a storage device such as a ROM (Read Only Memory) 902 and a RAM (Random Access Memory) 903, and an HDD (Hard Disk). Drive), an external storage device 904 such as a CD drive device, a communication I / F 905 for communicating with an externally connected device, and a bus 906 for connecting them, and a hardware configuration using a normal computer It has become.

  The moving image data depositing program executed in the moving image data depositing server 100 of the present embodiment is a file in an installable format or an executable format, and is a CD-ROM, flexible disk (FD), CD-R, DVD (Digital Versatile Disk). And the like recorded on a computer-readable recording medium.

  Further, the moving image data depositing program executed by the moving image data depositing server 100 of the present embodiment may be provided by being stored on a computer connected to a network such as the Internet and downloaded via the network. good. Further, the moving image data depositing program program executed by the moving image data depositing server 100 of the present embodiment may be provided or distributed via a network such as the Internet.

  Further, the moving image data deposit program of the present embodiment may be configured to be provided by being incorporated in advance in a ROM or the like.

  The moving image data depositing program executed by the moving image data depositing server 100 according to the present embodiment has a module configuration including the above-described units (communication unit, determination unit, combining unit, adding unit, authentication unit), As the hardware, a CPU (processor) 901 reads out and executes the moving image data deposit program from the storage medium, so that each unit is loaded on the main storage device, and a communication unit, a determination unit, a synthesis unit, an addition unit, and an authentication unit Are generated on the main memory.

  In addition, since the video data depositing server 100 according to the present embodiment does not need to be transmitted when the data is the same, the communication time is shortened to transmit the data, and the resources of the video data depositing server 100 and the home server 110A are reduced. Can be suppressed. Since the moving image data depositing server 100 manages moving image data requested to be deposited from a plurality of home servers in common, the moving image data occupying the storage unit 101 is reduced and the storage area can be used effectively. . In addition, since the moving image data that has already been deposited is not transmitted when depositing, traffic on the network can be reduced. The data depositing apparatus and the system including this apparatus according to the present invention are effective when transmitting and receiving a particularly large amount of data such as moving image data.

  In this embodiment, the data to be deposited is video data. However, the data that can be deposited is not limited to only video data, and can be specified by an identification ID such as music data, image data, or document data. As long as the data is correct.

(Second Embodiment)
In the first embodiment, when the moving image data is deposited between the moving image data depositing server 100 and the home server 110A, if the same moving image data is already deposited, the moving image data is not transmitted. However, when the amount of data is large, such as moving image data, it may be possible to receive a request to deposit the same moving image data from another home server while receiving moving image data from one home server. Therefore, in the second embodiment, a moving image data depositing server considering a case where a request for depositing the same moving image data is received from another home server while moving image data is being received from one home server, and The home server.

  FIG. 6 shows a network configuration of a moving image data depositing server 400 that realizes the function of the data depositing device according to the second embodiment of the present invention, and home servers 410A and 410B that manage home moving image data, and a moving image data depositing server. 4 is a block diagram showing the configuration of 400 and home server 410A. A home server other than the home servers 410A and 410B may be connected to the network shown in FIG. Note that the home server 410B is a home server having the same configuration as the home server 110A, and a description thereof will be omitted.

  The moving image data depositing server 400 shown in FIG. 6 includes a storage unit 101, a communication unit 402, a determination unit 403, a combining unit 404, an adding unit 405, an authentication unit 104, and a moving image data sharing unit 401. Yes. The moving image data depositing server 100 according to the first embodiment described above is added with the moving image data sharing unit 401, the combining unit 404 is added, and the communication unit 102, the determining unit 103, and the adding unit 105 are different in processing. The difference is that the communication unit 402, the determination unit 403, and the addition unit 405 have changed configurations. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The communication unit 402 includes a notification unit 421, an identification reception unit 122, a data transmission unit 123, and a data reception unit 422, and communicates with the home server 410A and the home server 410B connected via a public network. Note that the reason why the home servers that perform communication are 410A and home server 410B is for ease of explanation, and communication is possible if the home server has the same configuration as home server 410A.

  In addition to notifying the result of the custody request performed by the notification unit 121 according to the first embodiment, the notification unit 421 further sets the sharing of the data portion for transmitting moving image data for each home server by the moving image data sharing unit 401 described later. If so, the home server 410A, 410B, etc. are notified of a request to change the sharing of the transmission part of the moving image data, the identification ID, and the set data part.

  The data receiving unit 422 receives moving image data from the home server and accumulates it in the storage unit 101 in the same manner as the data receiving unit 124 of the first embodiment, but further transmits the moving image data notified by the notification unit 421. Based on this sharing, it is possible to receive one data portion of the moving image data from the home server 410A and receive the other data portion of the moving image data from the home server 110B. In addition, when the transmission part of the moving image data is shared, the data reception unit 422 receives a completion notification from each shared home server.

  The determination unit 403 receives a video data custody request from the other home server (for example, the home server 410B) via the communication unit 402 while receiving the moving image data from the one home server (for example, the home server 410A). In this case, it is determined whether or not the recognition ID received from the home server 410B together with the custody request matches the recognition ID specifying the moving image data being received from the home server 410A. When the determination unit 403 determines that they do not match, the recognition ID received together with the custody request and the identification ID included in the moving image data management table of the storage unit 101 are determined in the same manner as the determination unit 103 in the first embodiment. A comparison is made to determine whether there is a matching record. Note that whether or not there is a matching record by comparing the recognition ID received together with the custody request with the identification ID of the moving image data management table of the storage unit 101 is the same as in the first embodiment. Description is omitted.

  If the determination unit 403 determines that the recognition ID received together with the custody request matches the recognition ID for specifying the moving image data being received, the moving image data sharing unit 401 described later transmits the moving image data to the two home servers. Share the parts. Note that when the determination unit 403 has not received moving image data from any home server, the processing in the case of receiving a moving image data custody request from a certain home server is the same as the processing of the determination unit 103 of the first embodiment. Since there is, explanation is omitted.

  The moving image data sharing unit 401 has an identification ID that identifies moving image data being received by one of the home servers (assumed to be the home server 410A) by the determination unit 403, and a deposit from the other home server (assumed to be the home server 410B) When it is determined that the identification IDs sent together with the request match, the video data transmitted to the home server 410A and the home server 410B is shared.

  The setting of the sharing part performed by the moving picture data sharing unit 401 of the present embodiment acquires the communication speed of the home server 410A and the home server 410B, and the data part that has not yet been received in the moving picture data is set to the communication speed of these home servers. Set according to the ratio. Then, the notification unit 421 notifies the home server 410A and the home server 410B of the setting range of the data portion to be transmitted together with the change of the sharing of the data portion to which the moving image data is transmitted.

  In addition, after the video data sharing unit 401 shares the above-described procedure, there is a video data storage request from another home server, and the identification ID received together with the storage request identifies the video data that has been shared If the ID matches, the three home servers share the data portion of the moving image data that has not yet been received. Further, even when the number of units further increases, the data portion to be transmitted is shared according to the number of units. Even when three or more home servers share the data, the data portion of the moving image data that has not yet been received is shared according to the communication speed ratio of the home servers.

  When the data receiving unit 124 accumulates a plurality of data portions of the same moving image data from a plurality of home servers in the storage unit 101, the combining unit 404 merges these data portions into the storage unit 101 as one moving image data. accumulate.

  The adding unit 405 adds a record to the moving image data management table stored in the storage unit 101. When the moving image data is shared by a plurality of home servers, the adding unit 405 stores in the moving image data management table the identification ID, the storage location of the moving image data merged by the combining unit 404, and all the homes that have transmitted the shared data. A record in which a server ID indicating a server is associated is added. Since the procedure for adding a record or the like in other cases performed by the adding unit 405 is the same as that of the adding unit 105 of the first embodiment, description thereof will be omitted.

  Note that the present invention is not limited to the method of sharing the data portion that has not yet been received according to the communication speed when sharing the moving image data according to the present embodiment. For example, one home server still receives the data portion. A method may be considered in which data is transmitted from the start portion of the data portion that is not performed, data is transmitted from the end portion of the moving image data in the other home server, and transmission is terminated when the transmitted data matches.

  The home server 410A includes a storage unit 111, a communication unit 412, a deposit determination unit 113, a moving image acquisition unit 114, a moving image deletion unit 115, a reproduction processing unit 116, an identification ID generation unit 117, and an input processing unit 118. And a range setting unit 411. The home server 410A is different from the home server 110A of the first embodiment in that a range setting unit 411 is added and the communication unit 112 is changed to a communication unit 412 that is different in processing. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The range setting unit 411 transmits the moving image data specified by the received identification ID from the setting range of the transmitted data portion received together with the identification ID, indicating that the sharing of the transmission portion is changed from the moving image data depositing server 400 Set the range of the part. Thereby, the home server 410A can transmit the moving image data according to the sharing set by the moving image data depositing server 400.

  The communication unit 412 communicates with the moving image data deposit server 400 connected via a public network. The communication unit 412 receives the setting range of the data part to be transmitted together with the request to change the sharing of the transmission part, and outputs the setting range of the data part to be transmitted to the range setting unit 411. The communication unit 412 transmits the data portion of the moving image data for the range set by the range setting unit 411. The other transmission / reception performed by the communication unit 412 is the same as the transmission / reception performed by the communication unit 102 of the first embodiment, and is therefore omitted.

  Next, in the moving image data depositing server 400 and the home servers 410A and 410B according to the present embodiment configured as described above, transmission for depositing the moving image data from the home server 410A to the moving image data depositing server 400 is performed. When the moving image data depositing server 400 receives a deposit request from the home server 410B, the processing until the home server 410B deposits the moving image data will be described. FIG. 7 is a flowchart showing the above-described processing procedure in the moving image data deposit server 400, the home server 410A, and the home server 410B according to the present embodiment. It should be noted that the process of whether or not the identification ID transmitted together with the custody request from the home server 410B matches the identification ID held in the moving image data management table must also be performed, but the same process as in the first embodiment This is a procedure and will be omitted for ease of explanation.

  First, the processing procedure of the home server 410A will be described. The communication unit 412 of the home server 410A has already transmitted moving image data (step S531). Then, the communication unit 412 confirms whether or not the notification of the setting range of the data portion to be transmitted together with the identification ID has been received from the moving image data depositing server 400 to change the sharing of the data portion to be transmitted of the moving image data (step S532). . When the communication unit 412 receives the above notification (step S532: Yes), the range setting unit 411 sets the range of the data portion to which the moving image data is transmitted from the setting range of the data portion to be transmitted of the moving image data obtained by the notification. Set (step S533).

  The communication unit 412 of the home server 410A transmits the data portion of the moving image data based on the set range (step S534). Further, when the communication unit 412 does not receive the above-described notification and the range of the moving image data has never been set, the communication unit 412 determines that the moving image data is set as a range for transmitting all parts of the moving image data. Send.

  Then, the communication unit 412 of the home server 410A determines whether or not the data portion of the moving image data in the set transmission range has been transmitted (step S535). When the transmission of the moving image data has not ended (step S535: No), the communication unit 412 performs processing from the determination of whether or not the above-described notification has been received (step S532).

  In addition, when the communication unit 412 of the home server 410A ends the transmission of the moving image data (step S535: Yes), the communication unit 412 transmits a transmission completion notification to the moving image data depositing server 400 (step S536). Then, the moving image deletion unit 115 deletes the corresponding moving image data, and further deletes the file name of the record corresponding to the deleted moving image data in the moving image data identification ID management table stored in the storage unit 111, and the process ends (step S537). .

  Next, a processing procedure of the moving image data depositing server 100 will be described. The data receiving unit 422 receives moving image data from the home server 410A (step S511). Then, the data receiving unit 422 accumulates the received moving image data in the storage unit 101 (step S512). Then, the identification receiving unit 122 determines whether or not a video data storage request has been received from another home server (the home server 410B in this processing procedure) (step S513).

  When the identification receiving unit 122 receives a custody request for moving image data from the home server 410B (step S513: Yes), the determination unit 403 receives the moving image data received from the home server 410A with the identification ID received together with the custody request. It is determined whether or not it matches the identification ID to be identified (step S514). When it is determined that the determination unit 403 does not match (step S514: No), the determination unit 403 further determines whether or not it matches the identification ID of the moving image data management table stored in the storage unit 101. Since this is the same as the processing procedure shown in the first embodiment, description thereof is omitted (not shown).

  When it is determined that the determination unit 403 matches (step S514: Yes), the moving image data sharing unit 401 uses the home server 410A and the home server 410B to store the data portion of the moving image data being received that has not been transmitted yet. Sharing according to the communication speed (step S515). And the notification part 421 transmits the setting range of the data part transmitted with identification ID to the home server 410A and the home server 410B to the effect of changing the sharing of the data part which transmits moving image data (step S516).

  Then, the data receiving unit 422 receives moving image data from the home server 410B and the home server 410A (step S517). If the identification IDs of the moving image data transmitted from the home server 410B and the home server 410A by the determination unit 403 match, the data portion set by sharing the same moving image data is received from the home server 410A and the home server 410B. .

  Then, the data receiving unit 422 accumulates the received moving image data in the storage unit 101 (step S518). When the same moving image data is shared by the home server 410A and the home server 410B, the combining unit 404 merges the data portions of the moving image data received from the home servers. When different moving image data is received from the home server 410A and the home server 410B, the merge is not performed and the moving image data is accumulated.

  Then, the data receiving unit 422 confirms whether or not a transmission completion notification has been received from the home server (step S519). If the data receiving unit 422 shares the moving image data, the data receiving unit 422 confirms whether or not the transmission completion notification has been received from all the home servers that have been shared. When the video data is not shared, the transmission completion notification is not received from each home server. When the video data is shared, the transmission completion notification is not received from all the home servers (step S519: No), it starts again from the confirmation of whether or not the identification receiving unit 122 has received a custody request for moving image data from the home server (step S513).

  When the video data is not shared, when the transmission completion notification is received from each home server, and when the video data is shared, when the transmission completion notification is received from all the home servers (step S519: Yes), The adding unit 405 uses the identification ID of the moving image data as an identification ID for the moving image data management table in the storage unit 101, and specifies the identification ID, the storage location of the moving image data, and the home server that transmitted the moving image data A record is added in association with the ID (step S520). When moving image data is shared by a plurality of home servers and transmitted, the server IDs of all these home servers are added to the record.

  Next, a processing procedure of the moving image data depositing server 100 will be described. The communication unit 412 of the home server 410B transmits a custody request to the video data depositing server 400 together with an identification ID that identifies the video data (step S501). Then, the communication unit 412 confirms whether or not the notification of the setting range of the data portion to be transmitted is received from the moving image data depositing server 400 together with the change of the sharing of the data portion to which the moving image data is transmitted (step S502). When the communication unit 412 does not receive a notification to change the sharing of the data portion transmitted (step S502: No), the communication unit 412 receives the request result from the moving image data depositing server 400, and the moving image data depositing server 400 The processing is performed based on whether or not the same moving image data is stored, but the description is omitted (not shown) because it is the same as the processing from step S314 to step S315 shown in FIG. 4 of the first embodiment. .

  Then, in the home server 410B, similarly to steps S533 to S537 of the home server 410A, the transmission range of the moving image data is set by notification, the moving image data is transmitted by this setting, and after the transmission, the moving image data is deleted and the processing ends. Steps S503 to S507).

  In the above-described processing procedure, the processing procedure performed between the video data depositing server 400, the home server 410A, and the home server 410B has been described. However, the home server that transfers the video data to the video data depositing server 100 is referred to as the home server. The home server is not limited to 410A and 410B, and may be any home server connected to the moving image data depositing server 400 via a public network and having the same configuration as the home server 410A. In the processing procedure described above, the transmission of moving image data is shared by the home server 410A and the home server 410B, but the transmission of moving image data may be shared by a larger number of home servers.

  Further, the processing procedure described above is an example of a processing procedure shared by transmission of moving image data, and transmission of moving image data may be shared by another processing procedure.

  In addition, the moving image data depositing server 400 according to the present embodiment shares the same moving image data with a plurality of home servers and transmits the same moving image data, so that the moving image data depositing server 400 receives a data amount equal to or higher than the communication speed of the home servers 410A and 410B. It is possible to reduce the communication time for transmitting moving image data. Further, since it is not necessary for all the home servers 410A and 410B to transmit moving image data, it is possible to reduce the amount of data transmitted from each home server and to suppress a decrease in resources. The data depositing apparatus and the system including this apparatus according to the present invention are effective when transmitting and receiving a particularly large amount of data such as moving image data.

(Third embodiment)
In the first embodiment and the second embodiment, the same moving image data is handled for the same time and the same channel. However, if the moving image data is analog broadcasting, the data is different due to the difference in the environment on the receiving side, while the moving image data of digital broadcasting is kept completely identical. Therefore, in the third embodiment, analog broadcasting and digital broadcasting are discriminated, and a moving image data depositing server and a home server that share only moving image data of digital broadcasting with a plurality of home servers are used.

  FIG. 8 shows a network configuration of a moving picture data depositing server 600 that realizes the function of the data depositing apparatus according to the third embodiment of the present invention, and home servers 610A and 610B that manage home moving picture data, and a moving picture data depositing server. It is a block diagram which shows the structure of a home server. A home server other than the home servers 610A and 610B may be connected to the network shown in FIG. Note that the home server 610B is a home server having the same configuration as the home server 110A, and a description thereof will be omitted.

  The video data deposit server 600 shown in FIG. 8 includes a storage unit 101, a communication unit 402, a determination unit 602, a synthesis unit 404, an addition unit 405, an authentication unit 104, a video data sharing unit 401, a broadcast It consists of a form acquisition unit 601. The moving image data depositing server 400 according to the second embodiment described above has a configuration in which a broadcast form acquisition unit 601 is added and the determination unit 602 is different in processing from the determination unit 403. Different. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The determination unit 602 determines whether or not the identification ID received by the identification receiving unit 122 together with the moving image data deposit request matches the identification ID of the moving image data management table, and determines that the determination unit 602 matches. In this case, the identification ID is output to a broadcast form acquisition unit 601 described later, and it is determined whether the moving image data is a digital broadcast based on the result input from the broadcast form acquisition unit 601. If the determination unit 602 determines that the identification IDs match and that the moving image data is based on digital broadcasting, the notification unit 421 indicates that the same moving image data has already been stored, and the home request transmission request is transmitted. Send to server. If the determination unit 602 determines otherwise, the notification unit 421 transmits a request result indicating that the moving image data is transmitted to the home server (home server 610A or home server 610B in this embodiment) that transmitted the custody request. .

  In addition, when the data receiving unit 422 receives moving image data from one home server and the identification receiving unit 122 receives a moving image data storage request from the other home server, the determination unit 602 receives the moving image data together with the storage request. It is determined whether or not the recognized ID that identifies the received moving image data matches, and if the determination unit 602 determines that they match, the identification ID is further output to the broadcast form acquisition unit 601 and the broadcast form acquisition unit Based on the result input from 601, it is determined whether the moving image data is a digital broadcast. Then, when the determination unit 602 determines that the identification IDs match and the moving image data is from digital broadcasting, the moving image data sharing unit 401 determines that the moving image data has two home servers as in the second embodiment. The video data is shared, and the range of the data part to be transmitted to each home server is set. Further, when it is determined that it is other than that, the notification unit 421 transmits a request result to the effect that the moving image data is transmitted to the other home server that transmitted the custody request. The identification ID to be output to the broadcast mode acquisition unit 601 to determine whether the digital broadcasting or not when the identification ID matches may be one received from either the home server for identification ID matches.

  The broadcast form acquisition unit 601 acquires whether the broadcast in which the moving image data is recorded is a digital broadcast or an analog broadcast from the input identification ID. In the present embodiment, the identification ID is a combination of a recording start time, a recording end time, a numerical value indicating a recorded channel, and an identifier for determining whether the broadcast is digital broadcast or analog broadcast, and 'start time'- 'End time'-'Channel number'-'Broadcast form identifier'. The broadcast form identifier is “D” for digital broadcasting and “A” for analog broadcasting. For example, the identification ID of the moving image data recorded on the digital broadcast with the channel number '1' from 12:00 on July 31, 2004 to 14:00 on July 31, 2004 is 200407311200-200407311400 -1-A. Then, the broadcast form acquisition unit 601 extracts a broadcast form identifier from the identification ID, and outputs the digital broadcast or the analog broadcast to the determination unit 602. In the case of the identification ID of the example shown above, the broadcast form acquisition unit 601 outputs to the determination unit 602 that it is an analog broadcast.

  The home server 610A includes a storage unit 111, a communication unit 412, a deposit determination unit 113, a moving image acquisition unit 114, a moving image deletion unit 115, a reproduction processing unit 116, an identification ID generation unit 611, and an input processing unit 118. And a range setting unit 411. The home server 610A is different from the home server 410A of the second embodiment in that the configuration is changed to an identification ID generation unit 611 that is different in processing from the identification ID generation unit 117. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The identification ID generation unit 611 generates an identification ID associated with the moving image data acquired by the moving image acquisition unit 114, and adds the generated identification ID to the moving image data identification ID management table in association with the file name of the moving image data. Further, unlike the second embodiment, the identification ID generated by the identification ID generation unit 117 is a combination of a recording start time, a recording end time, and a recorded channel with a broadcast form identifier added, Time '-' end time '-' channel number '-' broadcast form identifier '. The broadcast form identifier is “D” for digital broadcast and “A” for analog broadcast. Whether the moving image data is based on digital broadcasting or analog broadcasting is acquired from the setting made on the device itself. Further, in the case of moving image data input from another recording device, it is acquired from another recording device whether or not it is a digital broadcast.

  The home server 610A of the present embodiment has the above-described configuration, so that when the moving image data depositing server 600 receives the identification ID, it can be determined whether the moving image data is a digital broadcast or an analog broadcast. Become.

  Next, in the moving image data depositing server 600 and the home server 610A according to the present embodiment configured as described above, after the home server 610A records the broadcast as moving image data, the moving image data depositing server 600 stores the moving image data. The processing up to deposit will be described. FIG. 9 is a flowchart showing a procedure of the above-described processing in the moving image data deposit server 600 and the home server 610A according to the present embodiment.

  First, the processing procedure of the home server 610A will be described. The processing procedure of the home server 610A is similar to steps S311 to S319 in FIG. 4 of the first embodiment, from broadcast recording to deletion of moving image data (steps S812 to S820). That is, home server 610A determines whether or not to transmit moving image data based on the request result received from moving image data depositing server 600 after transmitting the deposit request. Then, the home server 610A deletes the moving image data. Note that the identification ID generated by the identification ID generation unit 611 in step S813 is different from the identification ID of the first embodiment only in that an identifier for specifying whether the broadcast is analog broadcast or digital broadcast is added.

  Next, a processing procedure of the moving image data depositing server 600 will be described. The communication unit 402 receives the moving image data storage request together with the identification ID from the home server 610A (step S801). Then, the determination unit 602 compares the identification ID transmitted from the home server 610A and the identification ID included in the moving image data management table stored in the storage unit 101, and the moving image data having the matching identification ID by the presence or absence of a matching record. Is checked (step S802). When the determination unit 602 determines that the moving image data specified by the identification ID that matches the identification ID is stored (step S802: Yes), the broadcast form acquisition unit 601 extracts the broadcast form from the input identification ID. The result is output to the determination unit 602 (step S803).

  Then, the determination unit 602 determines whether the moving image data is based on digital broadcasting based on the result input from the broadcast form acquisition unit 601 (step S804). If the determination unit 602 determines that the moving image data is based on digital broadcasting (step S804: Yes), the determination unit 602 transmits a request result indicating that the same moving image data is stored in the home server 610A by the communication unit 402 (step S805). . Then, the adding unit 405 adds the server ID of the home server 610A to the server ID of the matched record, and the process ends (step S811).

  When the determination unit 602 determines that there is no matching identification ID (step S802: No), or when it is determined that the moving image data is not based on digital broadcasting (step S804: No), the first embodiment Similar to steps S306 to S309 in FIG. 4, a request result indicating that the same moving image data is not deposited is transmitted and the moving image data management table is updated (steps S806 to S810). That is, the moving image data received from the home server 610A is stored as no matching moving image data.

  If there is a matching identification ID and the moving image data is analog broadcast, the moving image data is received. Therefore, a plurality of records with the same identification ID are registered in the moving image data management table, and the moving image data cannot be specified. There is a possibility. However, even if the identification ID is the same, if the file name of the moving image data is changed or stored differently for each server, and the file name is searched based on the identification ID and the server ID, the moving image data transmitted by each home server is obtained. It becomes possible to specify. Although there are no particular restrictions on the method of changing the file name or the method of setting the storage location, in the case of moving image data of analog broadcasting, it is conceivable to always add a server ID to the received file name and store the file.

  In the present embodiment, when the video data depositing server 600 receives video data from the home server 610A, when there is a custody request from the home server 610B, the identification ID for identifying the video data being received and the custody If the identification IDs received together with the request match, the determination unit 602 further determines whether the broadcast is a digital broadcast, and is shared only when it is determined that the broadcast is a digital broadcast. The method for determining whether or not it is digital broadcasting is the same as the processing procedure shown in FIG. 9, and the sharing method after it is determined that it is digital broadcasting is the same as the processing procedure shown in FIG. Description is omitted.

  With this processing procedure, the data portion to be transmitted is shared only in the case of moving image data by digital broadcasting, and in the case of analog broadcasting, each home server transmits moving image data independently. In the case of moving image data by digital broadcasting, transmission of moving image data may be shared by a larger number of units, as in the second embodiment.

  In the present embodiment, when data is deposited from a plurality of home servers to a video data depository server, analog broadcast video data whose data differs depending on the environment or the like is held for each home server, and digital broadcasting in which identity is maintained It is possible to provide the same video data as the video data recorded in the home such as a home server, and the same video data as the video data deposited by the user can be provided. It becomes possible to satisfy the request of having acquired. Also, by storing the digital broadcast moving image data in common, the storage area occupied by the moving image data in the storage unit 101 of the moving image data depositing server 600 is reduced, and the storage area of the storage unit 101 can be used effectively. It becomes. In addition, since the moving image data is not received when it is a digital broadcast, the data transmission amount is reduced, and the communication time can be shortened.

  Whether the moving image data is digital broadcasting is determined by a method in which the home server embeds the identification ID and the moving image data depositing server 600 determines whether the moving image data is digital broadcasting based on the identifier extracted from the identification ID. The method is not limited, and any method may be used as long as it can determine whether the moving image data acquired from the home server is a digital broadcast.
