Hereinafter, embodiments will be described in detail.

(Embodiment 1)
In the first embodiment, a case where a service for distributing contents such as video, audio, and text information on the Internet (hereinafter referred to as an IPTV service) is used will be described as an example, but the present embodiment is not limited to the present embodiment. No.

<About IPTV service>
IPTV services are roughly classified into three services according to their form: streaming, download, and progressive download. In streaming, content data is sequentially distributed from the server to the client, and the client presents the data to the user by playing back video, audio, or the like from the arrived data. Therefore, when there is a network having a sufficiently wide bandwidth, the user can view the content in almost real time.

For download, the client acquires all of the content data from the server in advance and accumulates it, and after the accumulation is completed, viewing and playing is performed. Therefore, when it is not necessary to watch in real time, by completing and accumulating all the content data in advance, the user can watch it many times at a desired timing, and the network has a sufficiently wide bandwidth. The feature is that you can receive content distribution even if you are not.

In addition, the progressive download is located between these two, and before all the distribution of the content is completed, the progressive download is sequentially viewed from the stored in the terminal. This has the advantage that it is not always necessary to wait for the completion of storage, the storage time can be shortened even when the bandwidth is not wide enough, and the user can watch the video many times at the desired timing after the completion of storage. Can be provided.

In content distribution services including IPTV services, usage fees are often charged by service providers as compensation for users to receive distribution services. At this time, the user is registered in advance as a regular user, and various information such as a password, a name, and an address are managed by using an identifier such as an ID as a clue. The password may be biometric information such as a fingerprint.

In the case of distribution of paid content, it is possible to record billing information when accumulating or viewing, and it is confirmed that the usage fee can be paid by a payment method specified separately.

At the stage of using the distribution service, it is necessary to collate with the management information by the identifier and password of the registration information such as ID (IDentification) and to receive the user authentication to enable the service. This authenticated legitimate user is often provided with a content viewing portal screen for selecting and searching for content to be distributed and selecting other services such as information distribution.

In addition, it is confirmed by communication prior to the distribution service whether the device used by the user is the device recommended by the service provider or the program that receives the distribution service operating in the device is the recommended program. Often performs device certification. This will prevent acts that violate laws and regulations such as copyright law such as copying, moving, and modifying without permission, and unauthorized use of content.

At this time, the content is encrypted in advance by a common key cryptosystem so that only an authenticated legitimate user can decrypt it, or it can be decrypted only by an authenticated legitimate connected device. A key for decrypting the code may be separately received and held in association with the content so that it can be decrypted only by an authenticated legitimately connected device.

In addition, using the public key encryption method, the public key and private key are prepared by the connecting device or the service provider, and the private key is sent to the connecting device at the time of user registration, etc., and the service provider and the connecting device send the private key. It may be used for encryption and decryption, respectively.

Generally, these decryption keys are recorded together with the deadline and number of times the content is played back, and the playing conditions such as the user or device that can play the content. Hereinafter, the key for encryption is referred to as an encryption key, and the key for decryption is referred to as a decryption key.

In this way, the IPTV service provider acts on behalf of the content or service provider, and by associating the user authentication with the device authentication and the decryption key, the service provider acts on behalf of the content or service provider. Content distribution services and the like will be provided to users safely, and reliable billing will be made.

After that, the user receives the desired content and correctly gives and receives services such as content reproduction. Further, based on these, the user may be able to retain the linked content corresponding to the right to be reproduced based on the copyright.

The user plays back the content by a predetermined device using the content and the decryption key obtained in this way, but these are usually premised on the same device and the same user.

On the other hand, if the same user owns a plurality of devices and wants to play the same content on another device, there is an inconvenience that the same content will be charged again.

Therefore, there is a service that allows the same user who has the right to play the content to play the content on a plurality of devices within the range of the number of devices allowed by the service provider.

There is also a service in which application software is downloaded and purchased in the same way as content, and the function is enjoyed by operating the application software on the device side. Authorized authorized users are required to download applications on multiple devices within the number of devices allowed by the service provider if they are the same user who has the right to download the content as described above. Some services allow it.

In this case, the content / application synchronization processing unit 510 can synchronize the application between the wireless terminal 102 and the television receiver 101 by searching for a consistent application and downloading it from the content distribution server 106.

Next, when the cursor / decision button 1307 on the operation screen 1301 of the wireless terminal 102 is tapped, "operation information (selection)" is transmitted in the same manner as in the process of step S1203, and the television receiver 101 receives the received "operation information (selection)". Based on the "operation information (selection)", for example, the icon 1402 of the "content distribution service" in the App menu screen 1401 is selected (step S1204).

Various application units 508 of the television receiver 101 receive a command to start the browser and start the browser engine 502 (step S1205). The browser engine 502 refers to the user profile information saved in the process of step S1009 of FIG. 10 and accesses the content distribution server 106 of the content viewing portal preset in the wireless terminal 102.

Here, the address of the content viewing portal may be selected from the address list preset in, for example, "favorite setting" in the setting parameter of the user profile information, or the last accessed address is saved. You may set aside and access that address.

Then, the browser engine 502 sends a request message requesting resources such as Web contents conforming to HTTP (HyperText Transfer Protocol) from the external network 105 to the content distribution server 106 via the communication I / F 212 and the wireless router 104. Send.

The content distribution server 106 creates and returns a response message according to the received request message. The returned response message is input to the browser engine 502 via the external network 105.

An HTML document is embedded in the response message. The HTML parser 503 of the browser engine 502, the database generation unit 504, the rendering unit 505, and the image processing unit 506 work together to generate a browser display screen based on the HTML document, and the login screen of the content viewing portal is displayed on the display unit 210. Is displayed (step S1206).

On the login screen displayed by the above process, the control unit 214 notifies the browser engine 502 of the login information of the input user name and password by the same operation information as the process of step S1203, and requests the received character string. It is transmitted as a message to the content distribution server 106 (step S1207).

The content distribution server 106 refers to the user authentication information stored in the user authentication information 407 by the user management unit 701, and authenticates the user if it is a legitimate registered user (step S1206).

Here, in FIG. 12, in the process of step S1206, the login screen is displayed on the assumption that the user profile information is selected not to include the user authentication information for security reasons. However, it is also possible to automatically perform the authentication process by referring to the user ID and password of the user profile information saved in the process of step S1009 of FIG. In this case, the process of step S1206 can be omitted.

Subsequently, the content management unit 702 of the content distribution server 106 returns the content list information as a response message to the browser engine 502 when the authentication of the process in step S1208 is completed (step S1209).

The content list information transmitted here is information for displaying a list of contents managed by the content management unit 702, and includes information for identifying the managed contents.

When the browser engine 502 receives the content list information from the content management unit 702, the browser engine 502 includes the content ID for uniquely identifying the content, the content description information (genre title, performer, content, etc.), and the content reproduction. The content list display screen as shown in FIG. 15 is displayed on the display unit 210 with reference to the viewing charge, viewing period, and the like (step S1210). The content explanation information includes a genre title, performers, and content.

FIG. 15 is an explanatory diagram showing an example of display on the content list display screen of the television receiver 101 included in the network terminal system of FIG.

FIG. 15 shows that the Japanese movie button 1504 in the movie genre is selected. The end button 1505 is an operation unit for instructing to stop viewing the content by tapping.

On the screen shown in FIG. 15, when the title 1502 of the content to be viewed is selected on the content list display screen based on the operation information of the wireless terminal 102, the content detail display screen 1601 shown in FIG. 16 is displayed.

FIG. 16 is an explanatory diagram showing an example of display on the content detail display screen of the television receiver 101 included in the network terminal system of FIG.

In FIG. 16, the content detail section 1602 displays a title, performers, content details, and the like. The preview button 1604 is an operation unit for instructing the display of a part of the content in order to confirm a part of the content before purchasing. The index screen 1603 is a still image representing a scene of the content, and a part of the content can be displayed as a moving image by selecting the preview button 1604.

The purchase buttons 1605a and 1605b are operation units for selecting and purchasing content. In FIG. 16, in order to select and purchase HD (High Definition) image quality and SD (Standard Definition) image quality contents, purchase buttons 1605a and 1605b associated with each are provided. The back button 1606 is an operation unit for returning to the content list display screen of FIG. 15, that is, instructing switching of the display to the content list display screen.

On the content detail display screen shown in FIG. 16, when any of the purchase buttons 1605a and 1605b is selected based on the operation information of the wireless terminal 102 (step S1211), the control unit 214 tells the content distribution server 106 the content. The selection information is transmitted (step S1212).

The content selection information includes information for identifying desired content and, if necessary, information for identifying whether the desired content has HD image quality or SD image quality.

The content distribution server 106 generates key information for decrypting the content identified based on the content selection information, and transmits the key information to the television receiver 101 (step S1213).

The key information includes a decryption key for decrypting the encrypted content information, a content ID, an expiration date, an expiration date, and the like for each content. The key information transmission step (step S1213) may be omitted when the content requires encryption and is not required.

The television receiver 101 receives the key information from the content distribution server 106, and when the preparation for receiving the content is completed, transmits the content distribution start request (step S1214). The content distribution unit 703 of the content distribution server 106 that has received the distribution start request from the television receiver 101 starts content distribution to the television receiver 101 (step S1215).

In the screen shown in FIG. 11B, when the "playback" of the operation screen 1213 is tapped by the user's operation via the input unit 311 (step S1216), the wireless terminal 102 refers to the television receiver 101. Operation information ((reproduction) is transmitted (step S1217).

In the television receiver 101 that has received the operation information (reproduction), the content reproduction unit 507 performs the content reproduction processing. At this time, if there is a decryption key, the information of the encrypted content is decrypted by using the decryption key, and the reproduction of the content is started (step S1218).

When the operation button for the stop operation of the operation screen 1304 is selected on the operation screen shown in FIG. 13B (step S1219, the wireless terminal 102 transmits the operation information (stop) to the television receiver 101 (step S1220). ), The television receiver 101 transmits a distribution stop request to the content distribution server 106 (step S1221).

When the content distribution server 106 receives the distribution stop request from the television receiver 101, or the content distribution server 106 detects the end of the content (step S1222), the content distribution server 106 stops the distribution of the content (step S1223), and the television. A content distribution end notification is transmitted to the receiver 101 (step S1224).

Upon receiving the content distribution end notification, the television receiver 101 stops playing the content (step S1225). Here, when the television receiver 101 stops the reproduction in the process of step S1219, the television receiver 101 may return to the state before the start of the content reproduction.

Further, in the case of playback stop after the processing of step S1219, the information on the playback stop position of the content is stored as resume information in the profile information of the user of the wireless terminal 102 of the storage 216.

Then, when the playback operation is performed again via the wireless terminal 102 and the playback of the same content by the same user is resumed, the content playback unit 507 of the television receiver 101 acquires the position data at which playback has stopped from the resume information. , Playback can be resumed with that as the playback start position.

Further, the information of the content playback stop position can be held on the content distribution server 106 side. In this case, the content distribution server 106 transmits the information of the content playback stop position together with the content information in the process of step S1215.

As a result, the television receiver 101 can start distribution from the playback start position calculated based on the playback stop position information acquired from the content distribution server 106 together with the content information.

Further, the operation flow when the content is distributed from the content distribution server 106 and the content is reproduced has been described. However, all the content data is acquired and accumulated at the timing of the process of step S1215 in FIG. 12, and after the accumulation is completed. It may be viewed and played back. In this case, the process of step S1222 and the process of step S1223 in FIG. 12 are unnecessary.

Further, in the process of step S1213 for transmitting the key information, the television receiver 101 can also store the key information received from the content distribution server 106 in the storage 216. Alternatively, the key information can be discarded each time, and the key information can be acquired from the content distribution server at the timing of the process of step S1218 each time the content is played back.

Further, when the content downloaded from the content distribution server 106 is played back halfway on the wireless terminal 102 and the continuation is to be played back and viewed on the TV receiver 101, the content application synchronization of the TV receiver 101 is performed based on the user profile information. It is also possible to synchronize the downloaded contents between the wireless terminal 102 and the television receiver 101 by the processing unit 510.

Here, when the wireless terminal 102 is used alone, the content reproduction unit 607 performs the content reproduction processing in the same manner as the content reproduction unit 507 of the television receiver 101.

Next, the wireless terminal 102 and the wireless terminal 103 access the television receiver 101 at the same time, the television receiver 101 and the content distribution server 106 exchange content information, and the content list is displayed on the television receiver 101. The operation when the operation is performed will be described with reference to FIG.
