Note that when the reception of the acquisition request content is completed and the reproduction of the image based on the acquisition request content is completed, the process of step S229 is ended, and the process of step S224 is performed again.

  In the reproduction process, after all the data of the acquisition request content is downloaded, a process of reproducing and displaying the content image based on the acquisition request content on the display unit 630 may be performed.

  As described above, according to the present embodiment, video display device 600 does not have user identification information that is issued only to registered devices, but has another device (communication terminal) having user identification information. The device 500) performs an authentication process on behalf of the device 500, and after the authentication process is completed, the acquisition request content is received from the service server 800A, and a content image based on the acquisition request content is reproduced and displayed on the display unit 630.

  Therefore, the communication terminal device 500 can centrally manage a plurality of user identification information respectively corresponding to a plurality of content sites. That is, it is not necessary to register the service server 800A (content site) with both the communication terminal device 500 and the video display device 600. As a result, there is an effect that the service can be easily enjoyed without wasting the user.

  Further, the video display device 600 may be used by unspecified people such as friends and acquaintances. Note that video display apparatus 600 in the present embodiment does not manage user identification information. Therefore, it is possible to prevent an illegal act such that an unspecified person downloads paid content from a content site without permission by operating the video display device 600.

<Second Embodiment>
In the present embodiment, a description will be given of a process in which a communication terminal device that has received an authentication proxy request makes an authentication proxy request to another communication terminal device, and the other communication terminal device performs an authentication process.

In the following description, it is assumed that the two communication terminal devices 500 perform processing to be described later on the video display device 600. Hereinafter, one communication terminal apparatus 500 is also referred to as communication terminal apparatus A. The other communication terminal apparatus 500 is also referred to as communication terminal apparatus B. Assume that the device ID of the communication terminal device A is “11MA”. Assume that the device ID of the communication terminal device B is “11 MB”. Note that the number of communication terminal devices 500 is not limited to two, and may be three or more.

  Since the network system in the present embodiment is similar to network system 1000 in the first embodiment, detailed description will not be repeated. The configuration of each of communication terminal device 500, video display device 600, and service server 800A is the same as that described in the first embodiment, and therefore detailed description thereof will not be repeated.

  Also in the present embodiment, it is assumed that each of communication terminal apparatus A and communication terminal apparatus B is performing the registration process described in the first embodiment. Therefore, for example, the user identification information registration data table D100 of FIG. 12 is stored in each storage unit 520 of the communication terminal device A and the communication terminal device B.

  Next, a process when either the communication terminal apparatus A or the communication terminal apparatus B and the video display apparatus 600 access a registered content site (hereinafter also referred to as content site access process A) will be described. The content site access process A is a process for the video display device 600 to have the communication terminal device having the user identification information perform the authentication process, and for the video display device 600 to enjoy the service provided by the content site. . The service is, for example, streaming reception or download of content.

  Content site access processing A is processing performed when communication terminal apparatus A is set to the remote control mode and remote control image MG100 of FIG. 9 is displayed on display unit 530. Here, the button image MBG 130 is pressed by the interface operation M, so that the site name shown in FIG. 12 among the plurality of types of content sites registered in advance by the above-described registration processing is “BB service”. ”Is set to perform processing for accessing the content site.

  The content site whose site name is “BB service” is assumed to be a content site provided by the service server 800A. That is, the data of the content site whose site name is “BB service” is stored in the storage unit 820 of the service server 800A. Hereinafter, a content site to be accessed is also referred to as an access target content site. Here, as an example, it is assumed that the access target content site is a content site whose site name is “BB service”.

  It is assumed that the access target content site permits distribution of the requested content by receiving the corresponding user identification information. For example, if the content site to be accessed is a content site whose site name is “BB service”, distribution of the requested content is received by receiving information “bbkk” shown in FIG. 12 as user identification information. to approve.

  FIG. 20 is a flowchart of the content site access process A. FIG. 20 shows processing performed in each of communication terminal apparatus A, video display apparatus 600, and service server 800A. Referring to FIG. 20, content site access processing A is not performed in steps S215, S216, S217, S245, and S246 as compared to content site access processing in FIG. 13, and steps S214A and S244A. The difference is that the processing is further performed. Other than that, it is the same as the content site access processing, and therefore detailed description will not be repeated. Hereinafter, processing different from the content site access processing of the first embodiment will be mainly described.

  In the content site access processing A, the processing performed in each of the communication terminal device A, the video display device 600, and the service server 800A until the processing in step S214 is performed in the content site access processing of the first embodiment. Since it is the same as the process which replaced the communication terminal device 500 with the communication terminal device A, detailed description is not repeated.

  In service server 800A, after the process of step S244, the process proceeds to step S244A.

In step S244A, an authentication determination process is performed.
In communication terminal apparatus A, in step S214, the same processing as that of the first embodiment is performed, and thus detailed description will not be repeated. In step S214, assuming that an authentication proxy request has been received, the process proceeds to step S214A. Note that the authentication proxy request includes the device data D300 of FIG.

  In step S214A, proxy request processing is performed to have other communication terminal devices perform authentication processing. Here, it is assumed that the other communication terminal apparatus is the communication terminal apparatus B.

  FIG. 21 is a flowchart of proxy request processing, processing performed in communication terminal apparatus B, and authentication determination processing. Referring to FIG. 21, in the proxy request process performed by communication terminal apparatus A, first, the process of step S311 is performed.

  In step S311, control unit 510 transmits (transfers) the received authentication proxy request to communication terminal apparatus B. Note that the authentication proxy request includes the device data D300 of FIG. Thereafter, the process of step S311 ends.

In communication terminal apparatus B, first, the process of step S331 is performed.
In step S331, control unit 510 determines whether an authentication proxy request has been received. If YES in step S331, the process proceeds to step S335. On the other hand, if NO at step S331, the process at step S331 is performed again.

  In step S335, control unit 510 generates authentication request image MG300 in FIG. 18 and causes authentication request image MG300 to be displayed on display unit 530. Then, the process proceeds to step S336.

  In step S336, control unit 510 determines whether or not there is an authentication process execution operation. The authentication process execution operation is an interface operation M for pressing the button image MBG380. If YES in step S336, the process proceeds to step S337. On the other hand, if NO at step S336, the process at step S336 is performed again.

  In step S337, authentication processing A is performed. In the authentication process A, the control unit 510 accesses the service server 800A having the authentication Web page specified by the authentication URL, and the user identification information corresponding to the access target content site and the device ID of the video display device 600 ( 11TA) is transmitted to the service server 800A. Here, it is assumed that the authentication URL is “http://www.bb.com/certification/certification.html”. Further, it is assumed that the access target content site is a content site whose site name is “BB service”. In this case, the user identification information is information “bbkk” shown in FIG.

  In the authentication determination process performed by service server 800A, first, the process of step S345 is performed.

  In step S345, control unit 810 determines whether or not the authentication URL is accessed and user identification information (bbkk) and device ID corresponding to the access target content site are received. If YES in step S345, the authentication is successful, and the process proceeds to step S346. On the other hand, if NO at step S345, the authentication is unsuccessful and the process at step S345 is performed again.

  In step S346, an authentication completion process is performed. In the authentication completion processing, the control unit 810 causes the storage unit 820 to store the received device data D300 including the device ID “11TA”. With this processing, the device ID “11TA” becomes a registered device ID.

  In addition, the control unit 810 transmits the authentication completion data to the communication terminal apparatus B that has accessed the authentication URL. The authentication completion data is data including a message for notifying that the authentication is completed. Then, the process of step S346 ends, the authentication determination process ends, the process returns to the process of service server 800A of FIG. 20, the process of step S244A ends, and the process proceeds to step S247.

  In communication terminal apparatus B, in authentication process A of step S337, when control unit 510 determines that authentication completion data has been received, an image for informing that authentication process has been completed is displayed on display unit 530. Thereafter, the process of step S337 ends, and the process proceeds to step S338.

  If control unit 510 does not receive authentication completion data even after a predetermined time (for example, 5 minutes) has elapsed after transmitting the above-described data to service server 800A, control unit 510, for example, “authentication” The display unit 530 displays an image displaying a message “failure”. In this case, the process of step S336 is performed again.

  In step S338, control unit 510 transmits (transfers) the received authentication completion data to communication terminal apparatus A that has transmitted the authentication proxy request. Thereafter, the process of step S331 is performed again.

In the communication terminal device A, the process proceeds to step S318 after the process of step S311.
In step S318, control unit 510 determines whether or not authentication completion data has been received. If YES at step S318, control proceeds to step S319. On the other hand, if NO at step S318, the process at step S318 is performed again.

  If control unit 510 does not receive authentication completion data even after a predetermined time (for example, 5 minutes) has elapsed after transmitting the above-mentioned authentication proxy request to communication terminal apparatus A, control unit 510 may, for example, The display unit 530 displays an image displaying a message “Authentication failed”. In this case, the process of step S311 is performed again.

  In step S319, an authentication completion image display process is performed. In the authentication completion image display process, control unit 510 generates authentication completion image MG400 of FIG. 19 using received authentication completion data, and causes authentication unit MG400 to be displayed on display unit 530. Thereafter, the process of step S319 ends, the proxy request process ends, the process returns to the process of communication terminal apparatus A in FIG. 20, the process of step S214A ends, and the process proceeds to step S218.

  In step S218, the same processing as in the first embodiment is performed, and thus detailed description will not be repeated. Here, assuming that there is a reproduction operation, the process proceeds to step S219.

  In step S219, the same processing as in the first embodiment is performed, and thus detailed description will not be repeated. Through this process, a reproduction instruction including the title of the content to be acquired is transmitted to the video display device 600. Here, it is assumed that the title of the content to be acquired is “G movie”.

In the video display device 600, the process proceeds to step S228 after the process of step S227.
In step S228, the same processing as in the first embodiment is performed, and therefore detailed description will not be repeated. Here, assuming that a reproduction instruction has been received, the process proceeds to step S229.

  In step S229, the same processing as in the first embodiment is performed, and thus detailed description will not be repeated. By this processing, the control unit 610 accesses the service server 800A having the content specified by the URL of the acquisition target content corresponding to the title of the acquisition target content included in the received reproduction instruction with reference to the content list data D200. At the same time, the device ID of the device itself is transmitted to the service server 800A. Assume that the URL of the content to be acquired is “http://www.bb.com/down/content3.mpg”. It is assumed that the device ID of its own device is “11TA”.

  In service server 800A, the same processing as in the first embodiment is performed in step S247, and therefore detailed description will not be repeated. Here, assuming that the device ID is received, the process proceeds to step S248.

  In step S248, the same processing as in the first embodiment is performed, and thus detailed description will not be repeated. Through this process, the acquisition request content is streamed to the video display device 600. When the distribution of the acquisition request content ends, the process of step S248 ends, and the process of step S242 is performed again.

  In video display device 600, the same processing as in the first embodiment is performed in the reproduction processing in step S229, and therefore detailed description will not be repeated. By this processing, an image based on the acquisition request content is reproduced and displayed on the display unit 630. When the process of step S229 ends, the process of step S224 is performed again.

  As described above, according to the present embodiment, a communication terminal apparatus that has received an authentication proxy request makes an authentication proxy request to another communication terminal apparatus, and the other communication terminal apparatus performs an authentication process. Even in this case, the effect of the first embodiment can be obtained.

<Third Embodiment>
In the present embodiment, processing for displaying a list for selecting content in communication terminal device 500 will be described.

  Since the network system in the present embodiment is similar to network system 1000 in the first embodiment, detailed description will not be repeated. The configuration of each of communication terminal device 500, video display device 600, and service server 800A is the same as that described in the first embodiment, and therefore detailed description thereof will not be repeated.

  Also in the present embodiment, it is assumed that communication terminal apparatus 500 performs the registration process described in the first embodiment. Therefore, for example, the user identification information registration data table D100 of FIG. 12 is stored in the storage unit 520 of the communication terminal device 500.

  Next, processing when the communication terminal device 500 and the video display device 600 access a registered content site (hereinafter also referred to as content site access processing B) will be described. The content site access process B is a process for the video display device 600 to have the communication terminal device 500 having the user identification information perform an authentication process, and for the video display device 600 to enjoy a service provided by the content site. is there. The service is, for example, streaming reception or download of content.

  Content site access processing B is processing performed when communication terminal apparatus 500 is set to the remote control mode and remote control image MG100 of FIG. 9 is displayed on display unit 530. Here, the button image MBG 130 is pressed by the interface operation M, so that the site name shown in FIG. 12 among the plurality of types of content sites registered in advance by the above-described registration processing is “BB service”. ”Is set to perform processing for accessing the content site.

  The content site whose site name is “BB service” is assumed to be a content site provided by the service server 800A. That is, the data of the content site whose site name is “BB service” is stored in the storage unit 820 of the service server 800A. Hereinafter, a content site to be accessed is also referred to as an access target content site. Here, as an example, it is assumed that the access target content site is a content site whose site name is “BB service”.

  It is assumed that the access target content site permits distribution of the requested content by receiving the corresponding user identification information. For example, if the content site to be accessed is a content site whose site name is “BB service”, distribution of the requested content is received by receiving information “bbkk” shown in FIG. 12 as user identification information. to approve.

  FIG. 22 is a flowchart of the content site access process B. FIG. 22 shows processing performed in each of communication terminal device 500, video display device 600, and service server 800A.

  Referring to FIG. 22, content site access processing B is different from content site access processing in FIG. 13 in that step S218B is performed instead of step S218, and step S219B is performed instead of step S219. The difference is that step S222B is performed instead of step S222 and step S241B is performed instead of step S241.

  Further, in the content site access process B, compared to the content site access process, steps S223, S224, S225, S226, S242, S243, and S244 are not performed, and steps S217A, S217B, S217C, S227A, and S227B are performed. Furthermore, it is different from what is done. Other than that, it is the same as the content site access processing, and therefore detailed description will not be repeated. Hereinafter, processing different from the content site access processing of the first embodiment will be mainly described.

  In the content site access process B, the communication terminal device 500 first performs the process of step S210.

  In step S210, the same processing as in the first embodiment is performed, and therefore detailed description will not be repeated. Here, assuming that there is a site access operation, the process proceeds to step S211.

  In step S211, the same processing as in the first embodiment is performed, and thus detailed description will not be repeated. By this processing, a site access remote control signal as an access instruction is transmitted to the video display device 600. Thereafter, the process of step S211 ends.

In video display device 600, first, the process of step S220 is performed.
In step S220, the same processing as in the first embodiment is performed, and thus detailed description will not be repeated. Here, assuming that a site access remote control signal as an access instruction has been received, the process proceeds to step S221.

  In step S221, the same processing as in the first embodiment is performed, and thus detailed description will not be repeated. By this processing, the control unit 610 accesses the content site to be accessed. Therefore, the video display apparatus 600 accesses the service server 800A that provides the access target content site. Here, it is assumed that the content site to be accessed is a content site whose site name is “BB service”.

In service server 800A, first, the process of step S240 is performed.
In step S240, the same processing as in the first embodiment is performed, and thus detailed description will not be repeated. Here, assuming that the access target content site provided by service server 800A has been accessed, the process proceeds to step S241B.

In step S241B, control unit 810 transmits the content list data and the above-described authentication URL to video display device 600 that has accessed the access target content site. Assume that the content list data is the content list data D200 in FIG. The authentication URL is, for example, “http://www.bb.com/certification/certification.html”. Note that the authentication Web page data is stored in the storage unit 820. Thereafter, the process of step S241B ends. In video display device 600, the process proceeds to step S222B after the process of step S221.

  In step S222B, reception processing is performed. In the reception process, control unit 610 receives content list data D200 and authentication URL transmitted from service server 800A, and stores received content list data D200 and authentication URL in storage unit 620. Thereafter, the process proceeds to step S227.

  In step S227, authentication proxy request transmission processing is performed in the same manner as in the first embodiment, and therefore detailed description will not be repeated. Through this process, an authentication proxy request for proxying the authentication process is transmitted to communication terminal apparatus 500. The authentication proxy request includes the device data D300 of FIG.

  In the authentication proxy request transmission process, the control unit 610 generates the following request display image G200 and causes the display unit 630 to display the request display image G200. Thereafter, the process of step S227 ends. Note that the process of displaying the request display image G200 on the display unit 630 may not be performed.

  FIG. 23 is a diagram showing a request display image G200 as an example. Referring to FIG. 23, message image G110 is arranged in request display image G200. Message image G110 displays a message requesting that authentication processing be performed by the communication terminal device. The message is, for example, a message “Please perform authentication processing at the communication terminal device”.

  Referring to FIG. 22 again, communication terminal apparatus 500 proceeds to step S214 after the process of step S211.

  In step S214, the same processing as in the first embodiment is performed, and thus detailed description will not be repeated. Here, assuming that an authentication proxy request has been received, the process proceeds to step S215.

  In step S215, the same processing as in the first embodiment is performed, and thus detailed description will not be repeated. By this processing, the authentication request image MG300 of FIG. 18 is displayed on the display unit 530. Thereafter, the process proceeds to step S216.

  In step S216, the same processing as in the first embodiment is performed, and thus detailed description will not be repeated. Here, assuming that there is an authentication process execution operation, the process proceeds to step S217.

  In step S217, authentication processing is performed as in the first embodiment. Specifically, control unit 510 accesses service server 800A having the authentication Web page specified by the authentication URL, and also identifies the user identification information corresponding to the content site to be accessed and the device ID of video display device 600 ( 11TA) is transmitted to the service server 800A. Here, it is assumed that the authentication URL is “http://www.bb.com/certification/certification.html”. Further, it is assumed that the access target content site is a content site whose site name is “BB service”. In this case, the user identification information is information “bbkk” shown in FIG.

  In service server 800A, the process proceeds to step S245 after the process of step S241B.

  In step S245, the same processing as in the first embodiment is performed, and thus detailed description will not be repeated. Here, assuming that the authentication URL is accessed and the user identification information (bbkk) and device ID corresponding to the access target content site are received, the process proceeds to step S246.

  In step S246, the same processing as in the first embodiment is performed, and thus detailed description will not be repeated. By this processing, device data D300 including the device ID “11TA” is stored in the storage unit 820. That is, the device ID “11TA” is a registered device ID.

  In addition, the control unit 810 transmits authentication completion data to the communication terminal device 500 that has accessed the authentication URL. The authentication completion data is data including a message for notifying that the authentication is completed.

  In communication terminal device 500, in authentication processing of step S217, when control unit 510 determines that authentication completion data has been received, authentication completion image display processing is performed. In the authentication completion image display process, control unit 510 generates authentication completion image MG400 of FIG. 19 using received authentication completion data, and causes authentication unit MG400 to be displayed on display unit 530. Thereafter, the process of step S217 ends.

  If control unit 510 does not receive authentication completion data even after a predetermined time (for example, 5 minutes) has elapsed after transmitting the above-described data to service server 800A, control unit 510, for example, “authentication” The display unit 530 displays an image displaying a message “failure”. In this case, the process of step S216 is performed again.

Referring to FIG. 22 again, after the process of step S217, the process proceeds to step S217A.
In step S217A, control unit 510 transmits a list request to video display device 600. The list request is a request for acquiring a list of a plurality of contents that can be streamed or downloaded from the service server 800A.

In video display device 600, the process proceeds to step S227A after the process of step S227.
In step S227A, control unit 610 determines whether a list request has been received. If YES in step S227A, the process proceeds to step S227B. On the other hand, if NO at step S227A, the process at step S227A is performed again.

  In step S227B, simple list data transmission processing is performed. In the simple list data transmission process, the control unit 610 generates simple list data obtained by extracting only “title” as content information from the content list data, and transmits the generated simple list data to the communication terminal device 500. Assume that the content list data is, for example, the content list data D200 in FIG. In this case, the simple list data is the following simple list data D400. Thereafter, the process of step S227B ends.

  FIG. 24 is a diagram showing simple list data D400 as an example. Referring to FIG. 24, simple list data D400 is different from content list data D200 in FIG. 14 in that there are no “reproduction time” and “URL” items. Other than that, it is the same as content list data D200, and therefore detailed description will not be repeated.

  In step S222B described above, content list data A including information on the title, playback time, and URL of each of a plurality of contents in a certain genre (for example, sports) may be received. In this case, the content list data A is, for example, data obtained by replacing a plurality of titles with, for example, sports-related titles in the content list data D200 of FIG. In this case, the simple list data is data obtained by replacing a plurality of titles with, for example, sports-related titles in the simple list data D400.

  Referring to FIG. 22 again, communication terminal apparatus 500 proceeds to step S217B after the process of step S217A.

  In step S217B, control unit 510 determines whether or not simple list data has been received. If YES in step S217B, control unit 510 causes received simple list data to be stored in storage unit 520, and proceeds to step S217C. On the other hand, if NO at step S217B, the process at step S217B is performed again. Here, assuming that the simple list data D400 is received, the process proceeds to step S217C.

  In step S217C, control unit 510 generates a content list image using a plurality of content titles included in the received simple list data, and causes display unit 530 to display the content list image. Thereafter, the process of step S217C ends. Here, the simple list data is assumed to be simple list data D400, and the generated content list image is assumed to be the following content list image MG300.

  FIG. 25 is a diagram showing a content list image MG500 as an example. Referring to FIG. 25, list image MG510 and button image MBG585 are arranged in content list image MG500.

  List image MG510 displays titles of a plurality of contents shown in simple list data D400. The title of the content is content information.

  In list image MG510, a frame MSR512 is further arranged. A frame MSR512 is a frame for selecting a title displayed in the list image MG510. The frame MSR 512 moves up and down by a short press operation of the direction button 541A and the direction button 541B, respectively.

  The button image MBG585 is a button image for causing the content of the title selected by the frame MSR512 to be reproduced and displayed on the display unit 630 of the video display device 600 by being pressed by the interface operation M.

  Referring to FIG. 22 again, after the process of step S217C, the process proceeds to step S218B.

  In step S218B, control unit 510 determines whether or not there is a content reproduction operation. The content reproduction operation is an interface operation M for pressing the button image MBG585 in a state where a title is selected by the frame MSR512 in the content list image MG500. If YES at step S218B, the process proceeds to step S219B. On the other hand, if NO at step S218B, the process at step S218B is performed again.

  Here, as an example, it is assumed that there is a content reproduction operation for reproducing the content titled “G movie”, and the process proceeds to step S219B. Hereinafter, the content of the title selected by the frame MSR 512 when the button image MBG585 is pressed is also referred to as selected content.

  In step S219B, control unit 510 transmits a playback instruction for playing back the selected content to video display device 600. The reproduction instruction includes the title of the selected content. Here, it is assumed that the title of the selected content is “G movie”. Then, the process of step S219B ends, and the process of step S214 is performed again.

In video display device 600, the process proceeds to step S228 after the process of step S227B.
In step S228, the same processing as in the first embodiment is performed, and therefore detailed description will not be repeated. Here, assuming that a reproduction instruction has been received, the process proceeds to step S229.

  In step S229, a reproduction process is performed. In the reproduction process, the control unit 610 refers to the content list data D200 and accesses the service server 800A having the content specified by the URL of the selected content corresponding to the title of the selected content included in the received reproduction instruction.
