For example, the subscription service pays a predetermined contract fee, and only during the contract period, the content of a predetermined content group, downloaded content, or distribution is distributed by the user's playback terminal. It is a service that can play back content.

[0023] In general, subscription services include streaming playback services. However, in this specification, the user pays a predetermined contract fee, and the content of a predetermined content group during the contract period. Is a service that allows playback of downloaded content or content recorded on recording media, etc. The mechanism to realize is described. In particular, in this specification, when a user renews the contract period by continuously paying a predetermined contract fee, the content of the specified content group is downloaded or downloaded during the contract period. This section describes the mechanism for realizing services that play back content recorded on content or recording media.

In the present specification, description will be made on the assumption that a subscription service is used to download a content of a predetermined content group or to play back a content recorded on a downloaded recording medium or a recording medium. The content of the content group may be video data, music data, or other various information data. In addition, music distribution may be performed using communication function download, or may be recorded on a recording medium and distributed by mail, for example.

The receiving unit 101 receives a distribution request for content to be distributed (hereinafter “distribution target content” t ヽぅ) from a device capable of communicating with the content distribution device 100. The content to be distributed is, for example, content that can be viewed or listened to only within a predetermined valid period provided by the subscription service described above. Here, the configuration is such that the viewing can be performed only within a predetermined effective period, but the configuration may be such that the downloadable period, the number of times of viewing (or listening), that is, the number of times of playback can be limited.

[0068] In the description of FIG. 5, the navigation device 502, the PC 503, and the playback terminal 504 may have different powers owned by the same user 550. Each may be owned by a user 550 such as a friend or family member.

[0069] The subscription service server 501 distributes music to the navigation device 502 and the PC 503 owned by the user 550 based on a contract for distribution of predetermined music with the IJ user 550. The music distribution may be performed to a terminal registered in accordance with a contract with the user 550, not limited to the navigation device 502 or the PC 503. In addition, the distributed music may be given information that permits duplication or information that restricts the number of duplications. The navigation device 502 or PC 503 receiving the music distribution may generate a copy within the permitted number of copies and send the copy to another terminal. At this time, if, for example, the same valid period as the original music is set for the copy, the other terminal that received the copy will also be based on a contract with the user 550 regarding the distribution of the predetermined music. Playback can be restricted during a limited period.

[0070] Specifically, for example, the subscription service server 501 allows the user 550 to use a subscription service through a predetermined terminal such as the registered navigation device 502 or PC 503 according to the contracted period. You can download or play as many songs as you like from the songs in the music group prepared by server 501 and listen to them.

[0071] More specifically, for example, the subscription service server 501 is a content server that stores and manages music data, an authentication server that sets and manages the terminal authentication of the user 550 and the validity period of the music, Management of contract information and billing information It may be configured as a server group power that has power such as a billing server. For example, the server group does not have to be three, and may be a server that has one or more functions of a content server, an authentication server, and a billing server and that can realize all functions.

Here, an overview of music distribution by the subscription service server 501 will be described. When the subscription service server 501 receives a music download request from a predetermined terminal such as the navigation device 502 or the PC 503 registered in accordance with the contract with the user 550, the function of the authentication server It is verified whether or not the user 550 has a valid contract.

[0073] Further, the subscription service server 501 sets music to be distributed from the music group stored and managed by the function of the content server in accordance with the contract information of the user 550 managed by the function of the accounting server. Specifically, for example, the music to be distributed is set with a valid period according to the contract information and billing information for the music for which power is required such as the navigation device 502 and the PC 503.

[0074] Here, the valid period may be updated according to, for example, the payment status of the user 550, and is not only the end date of distribution but also information including the start date and the end date. It's okay. Further, instead of the delivery date, information regarding whether or not playback is possible may be set by setting a reproducible date. The validity period may be changed as appropriate by the provider providing the subscription service.

In the first embodiment, the validity period is set by the subscription service server 50 1 for the music to be distributed, but may be configured by each terminal. Specifically, for example, the terminal may acquire contract information or billing information, and may reproduce music according to the contract information or billing information.

[0076] Further, for example, when the connection to the subscription service server 501 via the network 510 by the navigation device 502 is unstable, the PC 503 ^ ^ —and owned by the user 550 from the subscription service server 501 The music may be distributed, and then the PC503 power may be transferred to the navigation device 502 owned by the same user 550.

[0077] The navigation device 502 is mounted on a moving body such as a vehicle, and is used for route guidance of the vehicle. In addition, the content recorded on the recording medium and the content acquired by the communication function are played back.

[0079] More specifically, for example, the navigation device 502 is owned by the user 550 who has made a contract for distribution of a predetermined music, and is used by a display unit, an audio output unit, etc. (not shown). It has a function to refer to a list and information of possible music pieces. Then, the selection of the music piece that the user 550 wants to listen to can be received from the user 550 through an operation unit (not shown) and the music piece can be reproduced.

[0080] The music to be reproduced may be downloaded from the subscription service server 501 or a plurality of music, for example. The downloaded music may be a music that can be listened to only for the valid period according to the contract.

[0081] The music to be played back may be music that has not been downloaded from the subscription service server 501. Specifically, for example, a music to be played may be selected from a music group stored and managed by the subscription service server 501, and then wait until the download is completed, and may be played along with the end of the download.

[0082] When playing a song, the navigation device 502 always obtains the valid period set for each song before accepting a playback instruction for each song, and if there is a song that is not within the valid period, The user 550 may be notified that the period is not valid. In addition to notifying the user 550, a billing instruction may be given to an Internet bank or the like.

[0083] Further, the navigation device 502 may not manage the validity period set for each piece of music, but may manage the validity period by a music reproduction program associated with each piece of music. In this case, a configuration may be adopted in which a song that is not valid is not played by a song playback program that accompanies the song.

[0084] Listening to music using the navigation device 502 is not limited to the valid period of listening when a playback instruction is received from the user 550, and is valid after the playback instruction is received. If it is determined that it is not within the period, generally try playing the song. It may be stopped within a time when listening is permitted, for example within 40 seconds.

[0085] When listening to a music piece by the navigation device 502, when a playback instruction is accepted, the past playback history recorded in the navigation device 502 is searched, and if the previous playback is within the valid period, When a song is played and then it is determined that the playback instruction is not within the valid period, playback of the song may be stopped within a time period generally accepted for audition, for example, 40 seconds. . Also, if the previous playback is outside the valid period, the music is not played immediately, the valid period of the music for which the playback instruction has been accepted is acquired, and the ability to play the music according to the obtained valid period is determined. It may be judged.

[0179] (Functional Configuration of Content Playback Device)

Next, a functional configuration of the content reproduction device 200 according to the second embodiment of the present invention will be described. The content reproduction device 200 according to the second embodiment requests a device that distributes predetermined content to set the effective period of the time-limited content when the effective time period is not set for the acquired time-limited content. Thus, the content playback apparatus 200 is different from that of the first embodiment. In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

[0180] Acquisition unit 207 acquires content that can be viewed or listened to in a predetermined effective period (hereinafter referred to as "time-limited content"). Specifically, for example, it is possible to obtain the device power for distributing predetermined contents via a network by downloading, or to obtain the power of a recording medium on which content with a fixed deadline is recorded. Also good.

[0181] When the validity period is not set in the time-limited content acquired by the acquisition unit 207, the requesting unit 208 requests the device that distributes the predetermined content to set the effective period of the time-limited content. Further, for example, when the time-limited content is acquired by the acquisition unit 207, the request unit 208 requests the device that distributes the predetermined content to set the effective period of the time-limited content. [0182] Furthermore, when the input unit 202 receives an input of a reproduction instruction for time-limited content, the request unit 208 may request the device that distributes the predetermined content to set a valid period of the time-limited content. . The request unit 208 acquires the content with a time limit by the acquisition unit 207, and sets the validity period of the content with a time limit to a device that distributes the predetermined content when an instruction to play the content with the time limit is issued for the first time. You may request. In this case, the playback control unit 204 may play back the content with a time limit if the date and time when the input of the playback instruction is received by the input unit 202 is within the valid period set according to the request by the request unit 208.ヽ.

[0183] Further, the request unit 208, for example, before the acquisition of the time-limited content by the acquisition unit 207, relates to the reproduction right with a time limit common to all content according to the subscription information of the subscription service.

In this case, the receiving unit 205 may receive information on the reproduction right with a time limit distributed by the acquisition request of the requesting unit 208. Then, the playback control unit 204 acquires the date and time when the input of the playback instruction is received by the input unit 202. If the playback is permitted according to the acquired playback right with a time limit, the playback control unit 204 acquires the playback unit 207. A configuration may be used in which a time-limited content is set and content with a time limit is played back.

(Content distribution processing procedure of content distribution device)

Next, the content distribution processing procedure of the content distribution apparatus 100 according to the second embodiment will be described with reference to FIG. FIG. 13 is a flowchart of a content distribution processing procedure of the content distribution apparatus according to the second embodiment. In the flowchart of FIG. 13, first, the receiving unit 101 waits until a valid period setting request for requesting the setting of the valid period of the content with a time limit is received from a device capable of communicating with the content distribution apparatus 100 (step S1301: No loop). The device that can communicate with the content distribution device 100 is, for example, any device that can communicate with the content distribution device 100 via a network, and is not included in the subscription service contract executed by the content distribution device 100. It ’s a device!

[0185] When a valid period setting request is received in step S1301 (step S 1301: Yes), the valid period setting request received in step S1301 by the specifying unit 102 A device capable of communicating (hereinafter, “device to be set” t) is transmitted (step S 13 02). Then, the acquisition unit 103 acquires billing information related to the payment of the price for the time-limited content in the setting target device specified in step S1302 (step S1303).

Next, the setting unit 104 determines whether or not there is content with a time limit that is already distributed and stored in the setting target device (step S1304). If it is determined in step S1304 that there is a time-limited content stored (step S1304: Yes), the validity period corresponding to the consideration in the billing information acquired in step S1303 is set (step S1305), A series of processing ends. On the other hand, if it is determined that there is no time-limited content stored (step S1304: No), the series of processing ends. When the receiving unit 101 receives an acquisition request for information related to a reproduction right with a time limit common to all contents, the setting unit 104 distributes information regarding the reproduction right with a time limit.

In the flowchart of FIG. 13, the force for which the effective period is set in step S1305 is not limited to this. For example, permission information related to permission to play content with a period may be set in the setting target content.

Further, in the flowchart of FIG. 13, the force for which the effective period is set in step S1305 is not limited to this. For example, the setting unit 104 may transmit information on the validity period to the setting target device without directly accessing the distribution target content already stored in the setting target device using communication or the like.

As described above, according to content distribution apparatus 100 of Embodiment 2, receiving section 101 receives an effective period setting request for requesting an effective period setting for communicable apparatus power-limited content. Then, every time the receiving unit 101 receives a valid period setting request, the setting unit 104 can perform distribution and set the valid period of the time-limited content stored in the setting target device.

[0190] Therefore, time-limited content with no valid period set can be distributed by a server that can be downloaded by any device, or can be distributed by a CD or the like. This allows users to download content, for example. Even if you don't need it, you can save time and effort for downloading by downloading the contents together on a device with a good communication environment or distributing the contents recorded on a recording medium such as a CD. Can do.

[0191] Furthermore, according to the content distribution apparatus 100 of the second embodiment, the setting unit 104 can set the valid period to the content with a time limit every time the receiving unit 101 receives the valid period setting request. Therefore, the validity period of the content with a time limit stored in the setting target device can be set for each content. As a result, the user can set the effective period of time-limited content without spending time.

[0192] (Content playback processing procedure of content playback device)

Next, the content reproduction processing procedure of the content reproduction apparatus 200 according to the second embodiment will be described with reference to FIG. FIG. 14 is a flowchart of a content reproduction processing procedure performed by the content reproduction apparatus according to the second embodiment. In the flowchart of FIG. 14, first, the acquisition unit 207 acquires time-limited content within a predetermined valid period (step S 1401).

Next, it is determined whether or not a valid period is set for the time-limited content acquired in step S1401 (step S1402). If the validity period is not set in step S1402 (step S1402: No), the request unit 208 requests the device that distributes the predetermined content to set the validity period of the time-limited content (step S1403). .

[0194] Next, the input unit 202 waits until an input of a playback instruction for a content with a time limit acquired in step S1401 is received (step S1404: No loop), and when an input of a playback instruction is received ( Step S1404: Yes), it is determined whether or not the date and time when the input of the reproduction instruction is accepted in Step S1404 is within the predetermined valid period set by the request from the request unit 208 (Step S1405).

[0195] In step S1405, if it is within the predetermined valid period (step S1405: Yes), the playback control unit 204 controls to play the time-limited content to which the playback instruction is input in step S1404 (step S1406). ), A series of processing ends. [0196] On the other hand, when the valid period is set in step S1402 (step S1402: Yes), the process proceeds to step S1404, the process up to step S1406 is performed, and the series of processes is terminated. If it is not within the predetermined valid period in step S 1405 (step S 1405: No), the series of processing is terminated as it is without reproducing the time-limited content for which the reproduction instruction is input in step S 1404.

[0197] In the flowchart of Fig. 4, it is assumed that content with a time limit is acquired in step S1401, but the present invention is not limited to this. Specifically, for example, it may be acquired by downloading the device power that delivers predetermined content via the network! /, And you can get it by inserting a CD with content recorded into the drive.

[0198] Also, in the flowchart of FIG. 14, when a time-limited content is acquired in step S1401, if the valid period is set in step S1402: No! However, this is not limited to the force that requests to set the validity period. Specifically, for example, when an input of a playback instruction is accepted in step S1404: Yes, it is determined whether or not the validity period is set, and it is determined that the validity period is set and that it is ヽ. You may be asked to set a validity period!

[0199] As described above, according to the content reproduction device 200 of the second embodiment, when the valid period is not set in the time-limited content acquired by the acquisition unit 207, the request unit 208 A device that distributes content can be requested to set a validity period for time-limited content.

[0200] Therefore, if the user subscribes to the subscription service even if the time-limited content with no valid period set or the time-limited content set to not viewable is recorded, the time limit is set. It is possible to set the validity period of attached content. As a result, for example, even if the communication environment is unstable, the user can download the contents collectively on a device with a good communication environment, or set the validity period for the content obtained from a CD, etc. You can watch it just by doing so, so you can save time and effort for downloading.

[0201] Also, according to the content reproduction device 200 of the second embodiment, the acquisition unit 207 determines the time limit. When the attached content is acquired, the request unit 208 can request the device that distributes the predetermined content to set the validity period of the time-limited content. Therefore, content with a time limit that does not have a valid period or a valid period is set! Because of this, it is set so that it cannot be viewed! / When the content with the time limit is acquired, if the user subscribes to the subscription service, the validity period of the time limit content can be set. As a result, for example, when a user acquires a content with a time limit that is not set to a valid period or a content with a time limit that is set to be unviewable, the user views all the content from the time of acquisition. be able to.

[0202] Note that according to the content playback device 200 of the second embodiment, when the valid period is not set in the acquired content with a time limit, or when viewing is disabled, the request unit 208 performs the predetermined processing. For example, before acquiring content with a time limit, depending on the subscription of the subscription service of the user, It may be possible to acquire a reproduction right with a time limit common to all contents. In this case, even if time-limited content with no valid period set or content with time limit set to not be viewable is acquired, it is necessary to request the device that distributes the predetermined content to set the valid period. Playing back the content acquired according to the time-limited playback rights acquired in advance, or setting the valid period on the content playback device 200 based on the time-based playback rights acquired in advance. Good.

[0203] Also, according to the content reproduction device 200 of the second embodiment, when the input unit 202 receives an input of a content reproduction instruction with a time limit, the validity period of the content with a time limit to a device that distributes the predetermined content Can be requested. Therefore, if a user subscribes to a subscription service when trying to play a content with a time limit that is not set to a valid period or a content with a time limit that cannot be viewed, It is possible to set the validity period of the content with a time limit. As a result, for example, if a user obtains a time-limited content that is set so that viewing is not possible if the content with a time limit is not set, the user himself / herself Since it only takes time to set the effective period for the content to be viewed, the time to set the effective period can be saved.

Example 2

[0204] Example 2 of the present invention will be described below. In the second embodiment, for example, the content distribution apparatus 100 according to the second embodiment of the present invention is implemented by a subscription service server that provides a subscription service, and a vehicle (including a four-wheeled vehicle and a two-wheeled vehicle) is used. An example will be described in which the content reproduction apparatus 200 according to the second embodiment of the present invention is implemented by a navigation apparatus mounted on a moving body. In the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

[0205] (Example of subscription service server valid period setting process)

Next, an example of a valid period setting process of the subscription service server 501 according to the second embodiment will be described with reference to FIG. FIG. 15 is a flowchart of an example of the validity period setting process of the subscription service server according to the second embodiment.

[0206] In the flowchart of FIG. 15, the subscription service server 501 first waits until it receives a valid period setting request for a device capable of communication by communication IZF714 (step S1501: No loop), and sends a valid period setting request. If accepted (step S1501: Yes), the CPU 701 identifies the requesting user based on the contract information recorded on the magnetic disk 705 or the optical disk 707 (step S1502).

Next, connection is made to the setting target device by communication IZF714 (step S1503). Furthermore, the communication IZF714 determines whether there is content with a time limit that has already been distributed by the subscription service server 501 among the content recorded in the setting terminal connected in step S 1503! (Step S1504). If it is determined in step S1504 that there is time-limited content already distributed (step S150 4: Yes), the contract information recorded on the user's magnetic disk 705 or optical disk 707 identified in step S1502 is confirmed. (Step S 1505).

[0208] Based on the contract information confirmed in step S 1505 !, the validity period is set in the time-limited content determined to have already been distributed in step S 1504! In step S 1506, it is determined whether there is time-limited content. [0209] If the valid period is set in step S 1506! And there is content with a time limit (step S1506: Yes), CPU 701 sets the valid period (step S 1507), A series of processing ends.

[0210] On the other hand, if there is no time-limited content already delivered in step S1504 (step S 1504: No), the valid period is set in step S 1506! In such a case (step S 1506: No), the series of processing ends.

[0211] In the flowchart of FIG. 15, the force for identifying the user in step S1502 is not limited to this. Specifically, for example, if you are a subscriber to a subscription service, you may display a message prompting you to sign up for a subscription service, or you can end the series of processes.

[0212] Further, in the flowchart of FIG. 15, the power for determining whether or not there is a time-limited content already distributed in step S1504 is not limited to this. Specifically, for example, it may be determined whether or not there is a content with a time limit that is not distributed by the subscription service server 501 but distributed by a predetermined CD or the like.

[0213] In the flowchart of FIG. 15, it is determined in step S1506 whether there is content with a time limit for which the validity period is not set, but this is not restrictive. Specifically, for example, without determining whether or not the validity period is set, the process proceeds to step S1507, and for all the contents that have been determined to be time-limited content already distributed in step S1504. A valid period may be set.

[0214] As described above, according to the subscription service server 501 of the second embodiment, the receiving unit 101 receives an effective period setting request for requesting setting of an effective period for a content with a time limit even with a communicable device power. Then, every time the receiving unit 101 receives a valid period setting request, the setting unit 104 can perform the distribution and set the valid period of the time-limited content stored in the setting target device. Note that the receiving unit 101 also has a time limit reproduction that is common to all contents from a communicable device only by receiving an effective period setting request for requesting the setting of an effective period for content with a time limit. A right acquisition request may be received. In this case, In response to reception of the request for acquisition of reproduction rights with a time limit from the reception unit 101, the determination unit 104 delivers information on the reproduction rights with a time limit.

[0215] Therefore, time-limited content with no valid period set can be distributed by a server or CD that can be downloaded to any device. As a result, for example, even if the user does not download the contents individually, the contents are downloaded together on a device having a communication environment, or the contents recorded on a recording medium such as a CD are downloaded. By distributing it, you can save download time and effort.

[0216] Also, according to the subscription service server 501 of the second embodiment, the setting unit 104 can set the valid period to content with a time limit every time the receiving unit 101 receives a valid period setting request. Therefore, it is possible to set the validity period of the time-limited content stored in the setting target device for each content. As a result, the user can set the effective period of the time-limited content without consuming much time.

As described above, according to the content distribution device 100, the content distribution method, the content distribution program, and the recording medium according to the second embodiment of the present invention, in the subscription service server 501 according to the second embodiment. When the valid period setting request is received from the setting target device, it is possible to set the valid period of the already distributed content. As a result, even if content with a time limit that has not been set in advance is distributed in a batch, the user can view content with a time limit only by setting the time limit. Therefore, even in a device with an unstable communication environment, it is possible to save the download effort, so that various contents can be viewed.

[0218] (Example of playback processing of navigation device)

Next, an example of a reproduction process of the navigation device 502 according to the second embodiment will be described with reference to FIG. FIG. 16 is a flowchart of an example of the reproduction process of the navigation device according to the second embodiment.

[0219] In the flowchart of FIG. 16, first, the navigation device 502 acquires content by the communication IZF814, the optical disk drive 806, or the magnetic disk drive 804. If the content is acquired (step S1601: Yes), wait until the content playback instruction is received by the input device 811 (step S1602: No loop).

[0220] When a content playback instruction is received (step S1602: Yes), the CPU 801 uses the subscription information recorded on the magnetic disk 805 or the optical disk 807 to change the content acquired in step S1601 to the subscription service. It is determined whether or not the content with a time limit distributed by the server 501 is available (step S1603). The contract information may be the same as the contract information described in Fig. 10 or Fig. 11! /.

[0221] If it is determined in step S1603 that the content is time-limited (step S1603: Yes), it is determined whether or not a valid period is set for the content determined to be time-limited content in step S1603 ( Step S1604) o If the valid period is set in step S1604 (step S1604: No), request the substituting service server 501 to set the valid period by communication IZF814 (step S1605) o Then, the effective period is set according to the content requested in step S1605 (step S1606).

[0222] Next, the current date and time is acquired by a timer (not shown) provided in the navigation device 502 (step S1607). Then, the CPU 801 determines whether or not the current date and time acquired in step S1607 is within the valid period set for the time-limited content (step S1608).

[0223] If it is determined in step S1608 that it is within the valid period (step S1608: Yes), the magnetic disk drive 804 or optical disk drive 806 is controlled by the CPU 801, and the content recorded on the magnetic disk 805 or optical disk 807 is recorded. Is played (step S1609), and the series of processing ends.

[0224] On the other hand, if it is not content with a time limit in step S1603 (step S1603: No), there is no restriction on reproduction, so that the process proceeds to step S1609, the content is reproduced, and the series of processing ends. If a valid period is set in step S1604 (step S1604: Yes), the process proceeds to step S1607, and the subsequent processing is repeated.

[0225] Furthermore, in step S 1608! /, If it is not within the valid period! /, (Step S 1608: No) The image IZF812 displays on the display 813 that the valid period is not within the valid period (step S1610), and the series of processing ends.

[0226] In the flowchart of Fig. 12, the playback process of the navigation device 502 has been described, but the present invention is not limited to this. Specifically, for example, the reproduction processing in FIG. 12 may be performed by the PC 503 or the reproduction terminal 504.

[0227] As described above, according to the navigation device 502 of the second embodiment, when the valid period is not set in the time-limited content acquired by the acquisition unit 207, the request unit 208 supplies the predetermined content. It is possible to request the delivery device to set the validity period of the time-limited content.

[0228] Therefore, even if a time-limited content with no valid period set or a content with a valid period set and thus not viewable is recorded, the user cannot record the time-limited content. If you are subscribed to a subscription service, you can set a validity period for time-limited content. As a result, for example, even if the communication environment is unstable, the user can download the data collectively on a device with a stable communication environment, or set the validity period for content acquired by a CD. Since it can be viewed by itself, it can save download time and effort.

[0229] Also, according to the navigation device 502 of the second embodiment, when the content with a time limit is acquired by the acquisition unit 207, the request unit 208 adds the content with the time limit to the device that delivers the predetermined content. It is possible to request the setting of the validity period. Therefore, if the user has subscribed to the subscription service when the time-limited content with no valid period set or the time-limited content set to be unavailable for viewing is acquired, the time-limited content is set. It is possible to set the valid period of. As a result, for example, if a user acquires a content with a time limit that is not set to a valid period and a content with a time limit that cannot be viewed, the user can view all the content from that time. can do.

[0230] Also, according to the navigation device 502 of the second embodiment, when the input unit 202 receives an input of a content-limited content reproduction instruction, the device distributes predetermined content. It is possible to request the setting of the validity period of the content with a time limit. Therefore, if a user subscribes to the subscription service when trying to play a content with a time limit that has not been set, or a content with a time limit that cannot be viewed, It is possible to set the validity period of attached content. As a result, for example, if a user acquires time-limited content that has not been set for a valid period or content that has been set to be non-viewable, the user can set the valid period for the content that he / she views. Since it only takes time, the time for setting the validity period can be saved. Note that, in the navigation device 502 of the second embodiment, the requesting unit 208 simply requests the setting of the effective period when the effective period of the time-limited content acquired by the acquiring unit 207 is not set. Prior to acquiring the content with a time limit according to 207, a request for acquisition of a reproduction right with a time limit common to all the contents may be made. Then, the valid period acquired by the acquisition unit 207 is set by the information on the limited playback right delivered in response to the request! .

[0231] As described above, according to the content reproduction apparatus 200, the content reproduction method, the content reproduction program, and the recording medium according to the second embodiment of the present invention, in the navigation apparatus 502 according to the second embodiment, Communication If the expiration date is not set for the content with a time limit acquired in IZF814, when the content with a time limit is acquired, or when a playback instruction for the content with a time limit is received by the input device 811, the setting of the effective period is set. Can be made. Therefore, it is possible to distribute time-limited content regardless of whether or not you are subscribed to a subscription service. As a result, even if the communication environment is unstable even if the communication environment is unstable, the user can set the effective period for the content distributed in advance using the optical disc 807 or the like. This saves time to download content.
