[0016] Referring to the accompanying drawings, preferred embodiments of a content distribution device, a content reproduction device, a content distribution method, a content reproduction method, a content distribution program, a content reproduction program, and a recording medium according to the present invention will be described below. Will be described in detail.

[0017] (Embodiment)

(Functional configuration of content distribution device)

First, the functional configuration of the content distribution apparatus 100 that is relevant to the embodiment of the present invention will be described. FIG. 1 is a block diagram showing an example of a functional configuration of a content distribution apparatus that works according to the present embodiment. In FIG. 1, a content distribution apparatus 100 includes a receiving unit 101, a specifying unit 102, an acquiring unit 103, a setting unit 104, and a distribution unit 105.

[0018] The content distribution apparatus 100 is a server group that performs a subscription service. For example, the subscription service allows a user to pay a predetermined contract fee. It is a service that allows you to download and play downloaded content.

[0019] In general, the subscription service also has a service that performs playback by streaming. In this specification, the user pays a predetermined contract fee so that the content of a predetermined content group can be obtained during the contract period. Download Yes describes the mechanism for realizing a service that allows playback of downloaded content. In particular, in this specification, when a user renews the contract period by continuously paying a predetermined contract fee, the contents of a predetermined content group are downloaded or downloaded during the contract period. Describe how to implement a service to play back downloaded content.

[0020] Note that, in this specification, description will be made on the assumption that a content of a predetermined content group is downloaded using the subscription service or the downloaded content is played back. The content of the content group may be video data, music data, or other various information data. You can also distribute music by downloading communication functions, or record it on a recording medium and distribute it by mail!

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.

[0022] The distribution request is, for example, specific information for specifying the distribution target content desired by the user, or a device to which the distribution target content desired by the user is distributed (hereinafter referred to as “distribution target device” t ヽぅ) Including specific information to identify! Specific information that identifies the content to be distributed includes, for example, metadata such as the title name and author name of the content, a song ID (IDentifier) such as a copyright number, and an identification number in the subscription service. There may be. Further, it may be information including a feature amount of the content or a part of the content. By including the feature amount and part of the content, Even if it is a content, it can be easily identified when there is a difference in the version of the recording environment.

The identification unit 102 identifies a distribution target device that distributes the distribution target content based on the distribution request received by the reception unit 101. For example, when a plurality of playback terminals are registered by a contract with a user, the distribution target device is a device for which distribution of content to be distributed is desired by the user. Therefore, the distribution target apparatus may be an apparatus different from the apparatus that has received the distribution request by the receiving unit 101.

[0024] The acquiring unit 103 acquires billing information related to payment of the price of the distribution target content in the distribution target device specified by the specifying unit 102. The billing information is information related to a predetermined contract fee paid by the user to the provider for the implementation of the subscription service. Specifically, the billing information is, for example, payment information such as a monthly fee or an annual fee for the subscription service, and information such as a contract period.

[0025] In addition, the acquisition unit 103 acquires new billing information related to payment for the distribution target content in the distribution target device specified by the specification unit 102. The new billing information is information on a predetermined contract fee that the user newly paid to the operator for the implementation of the subscription service. Specifically, the new billing information is related to, for example, monthly payments for subscription services newly paid during the contract period, payment information such as annual charges, extension information for contract periods, or re-contracts. Payment information.

[0026] The setting unit 104 sets an effective period corresponding to the consideration in the billing information acquired by the acquiring unit 103 to the distribution target content. The valid period is, for example, the contract continuation period of the subscription service, and is information on the end date of distribution and viewing for the content to be distributed. In addition, the valid period may include information on the start date of distribution and viewing for the content to be distributed.

[0027] When new charging information is acquired by the acquisition unit 103, the setting unit 104 is set by the distribution unit 105 described later and set to the distribution target content already stored in the distribution target device. The valid period is changed to a valid period according to the consideration in the new billing information. The setting unit 104 has already used a communication medium or the like to store the recording medium of the distribution target device. Directly access the delivery target content stored in the body and change the validity period set for the delivery target content.

[0028] Furthermore, when new charging information is acquired by the acquiring unit 103, the setting unit 104 may transmit information on the validity period according to the consideration in the new charging information to the distribution target device. The setting unit 104 does not directly access the distribution target content already stored in the recording medium of the distribution target device using communication or the like, and transmits the effective period information so that the distribution terminal device can change the effective period. To do.

[0029] In addition, the setting unit 104 sets permission information regarding permission to reproduce the distribution target content when the date and time when the distribution target content is requested by the distribution request received by the reception unit 101 is within the valid period. The effective period of the content to be distributed is managed by the content distribution device 100. In other words, the distribution target content is not set with a valid period, but only permission information indicating whether or not to permit reproduction is set.

The distribution unit 105 distributes the distribution target content whose validity period is set by the setting unit 104 to the distribution target device. The distribution unit 105 distributes the distribution target content for which permission information is set by the setting unit 104 to the distribution target device.

[0031] (Functional configuration of content reproduction apparatus)

Next, a functional configuration of the content reproduction apparatus 200 that is relevant to the embodiment of the present invention will be described. FIG. 2 is a block diagram showing an example of a functional configuration of a content reproduction apparatus that is useful in the present embodiment.

In FIG. 2, the content playback apparatus 200 includes a recording unit 201, an input unit 202, an output unit 203, a playback control unit 204, a receiving unit 205, and a changing unit 206. It should be noted that a configuration for reproducing and outputting such as a reading unit for reading content is also provided!

[0033] The content playback device 200 is mounted on a mobile body, for example, and can play back content that can be viewed or listened to within a predetermined effective period (hereinafter referred to as time-limited content) using a subscription service. It is good to do. The recording unit 201 records content with a time limit on a recording medium (not shown) during a predetermined valid period. The recording unit 201 also downloads content managed by a device that distributes predetermined content. You may also download multiple contents at once. The content distribution device 100 may be the device that distributes the predetermined content.

The input unit 202 receives an input of a reproduction instruction for content with a time limit recorded by the recording unit 201. Also, the input unit 202 accepts an input of a reproduction instruction for content managed by a device that distributes predetermined content, and then records it in the recording unit 201.

[0035] The output unit 203 is controlled by a reproduction control unit 204, which will be described later, and the content is reproduced. Specifically, the output unit 203 is, for example, a speaker or a display.

[0036] The reproduction control unit 204 reproduces the time-limited content when the input unit 202 receives the input of the reproduction instruction and is within the predetermined validity period. The predetermined validity period is set for time-limited content. The date and time when the input of the reproduction instruction is accepted is obtained by a timer (not shown) provided in the content reproduction apparatus 200. Also, the playback control unit 204 plays back the time-limited content when the date and time when the input of the playback instruction is received by the input unit 202 is within the valid period changed by the changing unit 206 described later.

[0037] When the input of the playback instruction is received by the input unit 202, the playback control unit 204 controls playback of the content with a time limit based on permission information regarding permission for playback set for the content with a time limit. In this case, the expiration date is not set for the content with a time limit, and only information on whether or not to allow reproduction is set.

[0038] Further, the playback control unit 204 starts playback of the content with a time limit from the time when the input of the playback instruction is received by the input unit 202. Thereafter, the date and time when the playback instruction is received. If it turns out that it is not, playback of the content with a time limit may be stopped. Therefore, the user can listen to the content immediately after receiving the reproduction instruction. The time from when playback is started until the power stops is generally within the time allowed for auditioning, for example within 40 seconds.

[0039] The receiving unit 205 receives information about the validity period of the time-limited content from an apparatus that distributes the predetermined content. The valid period information includes specific information for identifying content with a time limit, valid period information for each content, and the like. In addition, the information on the validity period may be accompanied by a program for changing the validity period of the content. [0040] When the receiving unit 205 receives information on the validity period of the time-limited content, the changing unit 206 changes the predetermined valid period. The validity period may be changed by a program preliminarily set in the content reproduction apparatus 200 or a program included in the validity period information.

[0041] (Content delivery processing procedure of content delivery device)

Next, the content distribution processing procedure of the content distribution apparatus 100 will be described with reference to FIG. FIG. 3 is a flowchart showing the content distribution processing procedure of the content distribution apparatus. In the flowchart of FIG. 3, the receiving unit 101 first waits until a distribution request regarding a request for content to be distributed is received from a device capable of communicating with the content distribution device 100 (step S301: No loop). The device that can communicate with the content distribution device 100 is, for example, a device that can communicate with the content distribution device 100 via a network and is included in a subscription service contract executed by the content distribution device 100.

In step S301, when a distribution request is received (step S301: Yes), the specifying unit 102 specifies a distribution target device (step S302). Then, the acquisition unit 103 acquires the billing information regarding the payment of the price of the distribution target content in the distribution target device specified in step S302 (step S303).

Next, the setting unit 104 sets an effective period corresponding to the consideration in the billing information acquired in step S303 for the distribution target content (step S304). Then, the distribution unit 105 distributes the distribution target content whose validity period is set in step S304 to the distribution target device (step S305).

[0044] Further, the process waits until new charging information is acquired by the acquiring unit 103 (step S3 06: No loop). When new billing information is acquired (step S306: Yes), the validity period set in the distribution target content distributed in step S305 by the setting unit 104 and already stored in the distribution target device is displayed in the step. The validity period corresponding to the consideration in the new billing information acquired in S306 is changed (step S307), and the series of processing ends.

[0045] In the flowchart of FIG. 3, the valid period is set in step S304. It is not limited to this. For example, permission information related to permission to play distribution target content may be set in the distribution target content.

In the flowchart of FIG. 3, the force for changing the effective period in step S307 is not limited to this. For example, the validating period information may be transmitted to the distribution terminal device by the setting unit 104 without using communication or the like to directly access the distribution target content already stored in the distribution target device.

[0047] As described above, according to content distribution apparatus 100 of the present embodiment, new billing information relating to payment of the price of distribution target content in the distribution target apparatus specified by specifying unit 102 is acquired. . Then, the setting unit 104 can change the effective period set for the distribution target content already stored in the distribution target apparatus to the effective period corresponding to the consideration in the new billing information.

[0048] Therefore, the setting unit 104 can automatically change the valid period of the content by paying a new subscription fee for the subscription service even when the valid period of the content has passed. This allows the user to extend the validity period without re-downloading the already downloaded music.

[0049] Also, according to content distribution apparatus 100 of the present embodiment, setting unit 104, when new charging information is acquired by acquisition unit 103, is valid according to the consideration in the new charging information. Can be transmitted to the distribution target apparatus.

[0050] Therefore, the setting unit 104 can change the effective period by transmitting information on the effective period to the distribution target apparatus even when the communication environment with the distribution target apparatus via the network is unstable. . As a result, the user can change the valid period set in the content even in a device having an unstable communication environment such as a navigation device mounted on a vehicle.

[0051] Also, according to the content distribution apparatus 100 of the present embodiment, when the requested date and time of the content to be distributed by the distribution request received by the receiving unit 101 is within the valid period, the setting unit 104 Permission information regarding permission to play content can be set. Therefore, when the distribution target content is played back by the distribution target device, the distribution target component is immediately checked without checking the validity period of the distribution target content. You can play the numbers. As a result, the user can start playback immediately when instructing playback of the content to be distributed.

[0052] (Content Playback Processing Procedure of Content Playback Device)

Next, the content playback processing procedure of the content playback device 200 will be described with reference to FIG. FIG. 4 is a flowchart showing the content reproduction processing procedure of the content reproduction apparatus. In the flowchart of FIG. 4, first, the time-limited content is recorded on the recording medium by the recording unit 201 for a predetermined valid period (step S401).

[0053] Next, the input unit 202 waits until it receives an input of a reproduction instruction for the time-limited content recorded on the recording medium by the recording unit 201 (step S402: No loop), and inputs the reproduction instruction. If it is received (step S402: Yes), it is determined whether or not the date and time when the input of the playback instruction is received in step S402 is within a predetermined valid period (step S403).

[0054] If it is within the predetermined valid period in step S403 (step S403: Yes), the playback control unit 204 controls to play the time-limited content to which the playback instruction is input in step S402 (step S404), A series of processing ends.

[0055] On the other hand, in step S403, if it is not within the predetermined valid period (step S403: No), the time-limited content to which the reproduction instruction is input in step S402 is not reproduced, Terminate the process.

In the flowchart of FIG. 4, the force for recording the time-limited content in step S401 is not limited to this. Specifically, for example, the input of a reproduction instruction may be accepted first, and then a device that distributes predetermined content via a network may be used to record downloaded content.

[0057] As described above, according to content reproduction device 200 of the present embodiment, if the date and time when input of reproduction instruction is accepted by input unit 202 is within a predetermined valid period, content with a time limit is reproduced. can do. As a result, the user can view the time-limited content many times within the effective period.

[0058] Also, according to the content reproduction apparatus 200 of the present embodiment, when the receiving unit 205 receives information on the validity period of the time-limited content, the changing unit 206 has a predetermined existence. The validity period can be changed. Therefore, the receiving unit 205 receives the information on the validity period from the device that distributes the predetermined content even when the communication environment with the device that distributes the predetermined content via the network is unstable. The validity period can be changed by 206. As a result, the user can change the valid period set in the content even in a device having an unstable communication environment such as a navigation device mounted on a vehicle.

[0059] Also, according to the content playback apparatus 200 of the present embodiment, the playback control unit 204, based on the permission information set in the time-limited content, when receiving an input of playback instruction by the input unit 202 Thus, it is possible to control the reproduction of time-limited content. Therefore, the playback control unit 204 may play back the time-limited content without waiting for the time to determine whether or not the date and time when the input of the playback instruction is received is within the validity period of the time-limited content. it can. As a result, even when the user issues a reproduction instruction for the distribution target content, the user can immediately start reproduction.

[0060] Also, according to the content playback apparatus 200 of the present embodiment, the playback control unit 204 starts playback of the time-limited content from the time when the input of the playback instruction is received by the input unit 202, and then the playback instruction If it is determined that the date and time when the request is received is not within the predetermined validity period, playback of the content with a time limit can be stopped. Therefore, the playback control unit 204 can play back the time-limited content without waiting for a time to determine whether or not the date when the input of the playback instruction is received is within the valid period of the time-limited content. As a result, even when the user gives an instruction to play the content to be distributed, the user can start playback immediately.

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.

[0066] Specifically, for example, the subscription service server 501 allows a 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. [0067] 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 music, Server group power may also be configured, such as a billing server that manages contract information and billing information with the subscriber 550. 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 outline 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.

[0069] 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 according to 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.

[0070] Here, the valid period may be updated according to the payment status of the user 550, for example, and is not only the end date of distribution but also information that combines the start date and 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 present embodiment, the validity period is set by the subscription service server 5001 for the music to be distributed, but it may be set by each terminal. Specifically, for example, the terminal may acquire contract information and billing information, and play music according to the contract information and billing information.

[0072] Also, for example, when the connection to the subscription service server 501 via the network 510 by the navigation device 502 is unstable, the subscription service server The PC 503 ^ ^ owned by the user 550 may be distributed from the server 501, and then the PC 503 power may be transferred to the navigation device 502 owned by the same user 550.

[0073] The navigation device 502 is mounted on a moving body such as a vehicle, and in addition to guiding the route of the vehicle, the navigation device 502 reproduces content recorded on a recording medium and content acquired by a communication function. .

Specifically, for example, music distributed by the subscription service server 501 can be listened to. The delivered music has, for example, a valid period for listening, and downloads the set music.

[0075] 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.

[0076] 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.

[0077] The music to be played back may be a 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.

[0078] 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.

[0079] 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. [0080] 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, the playback of the music may be stopped within a time period generally allowing for listening, for example, within 40 seconds.

[0081] 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.

[0137] If the execution of the subscription service contract is accepted in step S1001 (step S1001: Yes), it is determined whether or not the content I / F714 has received the content download request from the distribution target device power ( Step S1002). The distribution target device is a navigation device 502 or a PC 503 that has been contracted by a contract user.

[0138] When a content download request is accepted in step S1002 (step S1002: Yes), the CPU 701 refers to the contract information recorded on the magnetic disk 705 or optical disk 707 and determines whether or not the user is a subscription service user. (Step S1003).

[0139] If it is determined in step S 1003 that the user is a user (step S 1003: Yes),

The CPU 701 determines the contract information recorded on the magnetic disk 705 or optical disk 707.

It is then determined whether the contract period is ongoing (step S1004).

[0140] If the contract period is ongoing due to step S1004 (step S1004: Yes), the CPU

701 sets a valid period for the content received in step S1002 (step S1005).

[0141] Then, by communication IZF714, the time-limited content whose validity period is set in step S1005 is distributed to the distribution target device (step S1006), and the series of processing ends. [0142] On the other hand, if the subscription service contract cannot be accepted in step S1001 (step S1001: No), or if the contract period is not ongoing in step S1004 (step S1004: No), step S1001 is entered.

Extend the contract period (step S1103). Then, the communication IZF 714 is connected to the distribution target device (step S 1104).

Next, whether or not there is a time-limited content already distributed by the subscription service server 501 among the content recorded in the distribution terminal device connected in step S 1104 by the communication IZF714. Is determined (step S1105). If it is determined in step S1105 that there is a time-limited content that has already been distributed (step S1105: Yes), then in step S1103, the contract is extended to the extended magnetic disk 705 or optical disk 707. The recorded contract information is confirmed (step S1106).

[0148] Based on the contract information confirmed in step S1106 !, the validity period is changed among the time-limited contents determined to have already been distributed in step S1105! It is determined whether or not there is a content with a time limit (step S1107).

If there is content with a time limit for changing the valid period in step S1107 (step S1107: Yes), CPU 701 changes the valid period (step S1108) and ends the series of processing.

[0150] As described above, according to the subscription service server 501 of the embodiment, new billing information regarding payment of the price of the distribution target content in the distribution target device specified by the specifying unit 102 is acquired. Then, the setting unit 104 can change the effective period set in the distribution target content already stored in the distribution target device to an effective period corresponding to the consideration in the new billing information.

Accordingly, the setting unit 104 can automatically change the valid period of the content by paying a new subscription fee for the subscription service even when the valid period of the content has passed. This allows the user to extend the validity period without re-downloading the already downloaded music.

[0152] Also, according to the subscription service server 501 of the embodiment, the setting unit 104, when new charging information is acquired by the acquiring unit 103, information on the validity period according to the consideration in the new charging information Can be transmitted to the distribution target device.

Therefore, the setting unit 104 can change the effective period by transmitting information on the effective period to the distribution target apparatus even when the communication environment with the distribution target apparatus via the network is unstable. . As a result, the user can change the valid period set in the content even in a device having an unstable communication environment such as a navigation device mounted on a vehicle.

[0154] Also, according to the subscription service server 501 of the embodiment, the date and time when the content requested by the distribution request received by the receiving unit 101 is within the valid period by the setting unit 104. In addition, permission information related to permission to play the content to be distributed can be set.

Therefore, when the distribution target content is reproduced by the distribution target device, the distribution target content can be reproduced immediately without checking the validity period of the distribution target content. As a result, the user issues an instruction to play the content to be distributed. If this happens, playback can be started immediately.

As described above, according to the content distribution device, content distribution method, content distribution program, and recording medium of the present invention, the subscription service server 501 records on the magnetic disk 705 or the optical disk 707.

[0157] (Example of playback processing of navigation device)

Next, with reference to FIG. 12, an example of the reproduction process of the navigation device 502 that is useful in the present embodiment will be described. FIG. 12 is a flowchart showing an example of the reproduction process of the navigation device that is useful in this embodiment.

[0158] In the flowchart of FIG. 12, first, the navigation apparatus 502 waits until a content playback instruction is received by the input device 811 (step S1201: No loop), and receives a content playback instruction. (Step S1201: Yes), the CPU 801 determines whether the content accepted in Step S 1201 is delivered by the subscription service server 501 based on the contract information recorded on the magnetic disk 805 or the optical disk 807. Is determined (step S1202). The contract information may be the same as the contract information described in Figure 10 or Figure 11! /.

[0159] If it is determined in step S 1202 that the content has a time limit (step S 1202: Yes), the current date and time is acquired by a timer (not shown) provided in the navigation device 502 (step S1203). Then, the CPU 801 determines whether or not the current date and time acquired in step S 1203 is within the effective period set in the time-limited content (step S 1204).

[0160] If it is determined in step S 1204 that it is within the valid period (step S 1204: Yes), the magnetic disk drive 804 or the optical disk drive 806 is controlled by the CPU 801, and the magnetic disk 805 or The content recorded on the optical disk 807 is played back (Step S 1205).

[0161] On the other hand, if it is not content with a time limit in step S1202 (step S1202 ) Since there is no restriction on reproduction, the process proceeds to step S1205 to reproduce the content. If it is not within the valid period in step S 1204 (step S 1204: No), the video iZF 812 displays on the display 813 that it is not within the valid period (step S 120 6). The process ends.

[0162] In the flowchart of Fig. 12, the reproduction processing 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.

[0163] As described above, according to the navigation device 502 of the embodiment, if the date and time when the input of the playback instruction is received by the input unit 202 is within a predetermined valid period, the time-limited content can be played back. it can. As a result, the user can view the time-limited content many times within the effective period.

Further, according to the navigation device 502 of the embodiment, when the information on the validity period of the content with a time limit is received by the receiving unit 205, the predetermined valid period can be changed by the changing unit 206.

[0165] Therefore, the receiving unit 205 can receive information on the validity period of the device that distributes the predetermined content even when the communication environment with the device that distributes the predetermined content via the network is unstable. The valid period can be changed by the changing unit 206. As a result, the user can change the valid period set in the content even in a device with unstable communication environment such as a navigation device mounted on a vehicle.

[0166] Also, according to the navigation device 502 of the embodiment, when the input of the playback instruction is received by the input unit 202, the playback control unit 204 has a time limit based on the permission information set for the time-limited content. Content playback can be controlled.

[0167] Therefore, the playback control unit 204 can play back the time-limited content without waiting for the time to determine whether the content within the effective period of the date / time power / time limit content received the input of the playback instruction is valid. . As a result, even when the user issues a reproduction instruction for the distribution target content, the user can immediately start reproduction.

[0168] Also, according to the navigation device 502 of the embodiment, the playback control unit 204 starts playback of the time-limited content from the time when the input unit 202 receives the input of the playback instruction, Thereafter, when it is determined that the date and time when the playback instruction is received is not within the predetermined valid period, playback of the content with a time limit can be stopped.

[0169] Therefore, the playback control unit 204 can play back the time-limited content without waiting for the time to determine whether the content within the effective period of the date-time power content that has received the input of the playback instruction is valid or not. . As a result, even when the user issues a reproduction instruction for the distribution target content, the user can immediately start reproduction.

As described above, according to the content playback apparatus, content playback method, content playback program, and recording medium of the present invention, the date and time when the playback instruction is received by the input device 811 in the navigation device 502 is determined. If the content is within the valid period set, the content can be viewed. As a result, the user can view the content with a time limit many times within the effective period.

[0171] Note that the content distribution method and content reproduction method described in the present embodiment can be realized by executing a prepared program on a computer such as a personal computer or a workstation. . This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM ゝ MO, and a DVD, and is executed by being read by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
