  The content acquisition unit 14 is a functional unit that acquires (downloads) content from the content providing device 4 based on operation information from the operation unit 13 based on a user operation. In the content acquired in this embodiment, in addition to the original image information of the content, identification information (for example, URL, content name) for identifying the content, and how much the content may be disclosed to others Including a disclosure level that indicates

  The content transfer display control unit 15 performs processing for displaying the content on the display unit 12, creates screen information for transfer to the display device 2 according to the disclosure level, and the like. Is a functional unit that transfers the data via the communication unit 11.

  More specifically, the content transfer display control unit 15 includes a content storage unit 151, a content display processing unit 152, a transfer screen information generation unit 153, a disclosure control unit 154, and a disclosure control information storage unit 155. The content storage unit 151 is a storage unit that stores the content acquired by the content acquisition unit 14. The content display processing unit 152 is a functional unit that performs processing for reading content from the content storage unit 151 and displaying the content on the display unit 12. For example, the content display processing unit 152 has a function for decoding encoded content and a graphic storage area ( Functions for graphic processing including graphic memory). The transfer screen information generation unit 153 is a functional unit that generates transfer screen information by performing non-disclosure processing or the like as necessary based on control information received from the disclosure control unit 154.

  The disclosure control unit 154 acquires the disclosure level of the content to be displayed from the content storage unit 151, refers to the disclosure control information table stored in the disclosure control information storage unit 155, and displays the disclosure control content for the content. It has a function of determining and passing the determination result to the transfer screen information generation unit 153 as control information.

The “computer” may be a mobile phone or the like having the function of “computer”.

(System operation)
Next, an example of the operation of the system in the present embodiment will be described with reference to the sequence chart of FIG.

  First, the display device 1 uses the content acquisition unit 14 to transmit a content request to the content providing device 4 (step 1), and acquires content from the content providing device 4 (step 2). The content acquisition unit 14 that has acquired the content stores the acquired content in the content storage unit 151.

  On the other hand, the display device 2 transmits a screen sharing request to the display device 1 (step 3), and the display device 1 transmits screen sharing permission to the display device 2, whereby screen sharing is started. Thereafter, the screen information displayed on the display device 1 (content acquired from the content providing device 4 in this embodiment) is also displayed on the display device 2. However, as will be described below, disclosure control is performed according to the disclosure level.

  In the example illustrated in FIG. 4, the screen sharing request is transmitted from the display device 2, and the display device 1 transmits the screen sharing permission to the display device 2. However, the screen sharing request is transmitted from the display device 1. The display device 2 may send a screen sharing permission to the display device 2. Moreover, starting the screen sharing process by transmitting and receiving a screen sharing request and a screen sharing permission is merely an example, and screen sharing may be started by another procedure. The timing for starting screen sharing is arbitrary, and for example, screen sharing may be started before content is downloaded.

  Subsequent to step 4, the user of the display device 1 performs an operation for content display. Then, the content display processing unit 152 performs processing for reading the content from the content storage unit 151 and displaying it on the display unit 12 (step 5). This is a normal content display process in the display device 1. On the other hand, as described below, processing for transferring content screen information including non-disclosure processing as necessary is performed.

  The disclosure control unit 154 of the content transfer display control unit 15 reads the disclosure level of the content from the content storage unit 151, and determines the disclosure control content corresponding to the disclosure level of the content by referring to the disclosure control information storage unit 155. Then, the contents are transferred as control information to the transfer screen information generation unit 153 (step 6).

  The transfer screen information generation unit 153 that has received the control information creates transfer screen information according to the control information (step 7), and the transfer screen information is transmitted to the display device 2 (step 8). Is displayed. In addition to the transfer image information, the content download destination URL, site name, and the like may be sent to the display device 2. As a result, the display device 2 stores the information in the device (bookmark registration), so that the display device 2 can access the content site.

  A specific example of the disclosure control process for each disclosure level shown in FIG. 3 will be described below.

(1) Case of “Disclosure” When the disclosure level is “Disclosure”, the content is disclosed to the display device 2 as it is. That is, in this case, the transfer screen information generation unit 153 acquires display image information (capture data of the display screen) of the target content from the content display processing unit 152, and uses the display image information as it is for transfer screen information. (Step 7) and transmitted to the display device 2 (step 8). The display image information may be compressed. As described above, when the display screen capture data is used, for example, the display image information acquisition of the content and the transfer screen information transmission are repeated at regular intervals. Further, instead of using the capture data as described above, the content read from the content storage unit 151 may be transmitted as it is to the display device 2 as transfer screen information.

(2) Case of “disclosure for a certain period” Next, “disclosure for a certain period” will be described. “Disclosed for a certain period” assumes that the content is mainly a moving image, but may be a still image. When the disclosure level is “disclosure for a certain period”, the transfer screen information generation unit 153 displays the content only for a predetermined period (time) from the start of the content display process (content display instruction by the user). To be disclosed. That is, in this case, the transfer screen information generation unit 153 acquires display image information (capture data of the display screen) of the target content from the content display processing unit 152, and uses the display image information as transfer screen information. (Step 7) The process of transmitting to the display device 2 (Step 8) is repeated from the start of the content display process until a predetermined period.

  Then, after a predetermined period has elapsed, an image obtained by masking the display image information of the content is set as transfer screen information and transmitted. Here, the processing to be performed for non-disclosure may be processing that hides everything like a mask, or processing that hides and hides each part of an image so that the contents of the image are not known, such as a mosaic. Alternatively, instead of creating the transfer screen information by masking the display image information of the content, a mask image may be prepared and transmitted without using the display image information of the content. Good. Further, the content name (video program name or the like) may be acquired from the content identification information, and an image having the name described on the mask may be transmitted as transfer screen information. An example of display transition in the case of “disclosure for a certain period” is shown in FIG.

(3) In the case of “non-disclosure” When the disclosure level is “non-disclosure”, the transfer processing of the image subjected to the mask or the like described above is performed from the start of the content display processing.

(4) In the case of “disclosure if paying” When the disclosure level is “disclosure if paying”, the content to the display device 2 when the fee for disclosure to the display device 2 is paid to the content provider. Disclosure is to be made. Processing in this case will be described with reference to FIG. In the process shown in FIG. 6, the process after step 6 is different from the process shown in FIG.

  When it is determined in step 6 that the control of “disclosure if paying” is performed, the disclosure control unit 154 indicates the content indicating “disclosure if paying” on the display unit 12 (that is, content inquiring content purchase). When the user gives a purchase permission operation (step 11), the disclosure control unit 154 transmits a content purchase request to the content providing apparatus 4 using the identification information of the content (step 11). Step 12). Thereafter, billing processing (payment processing for content) is performed between the display device 1 (disclosure control unit 154) and the content providing device 4 (step 13).

  After the payment is made in this way, for example, the display device 1 receives the permission information indicating the disclosure permission from the content providing device 4, and the disclosure control unit 154 confirming that the payment has been performed, The transfer screen information generation unit 153 is notified of the control information shown. The subsequent processing is the same as the processing when the disclosure level is “disclosure” (steps 7 and 8).

  Further, when the disclosure level is “disclosure if paying”, the processing procedure shown in FIG. 7 may be used. In this case, when it is determined in step 6 that control corresponding to “disclosure by payment” is performed, the disclosure control unit 154 displays a content purchase request (including information that can identify the content such as a content name). It transmits to the apparatus 2 (step 21). On the display unit of the display device 2, content indicating “disclosure if paid” (that is, content for inquiring content purchase) is displayed on the screen, and a purchase permission operation is performed by the user of the display device 2 (steps). 22) The display device 2 transmits a content purchase request to the content providing device 4 using the identification information of the content (step 23). Thereafter, billing processing (payment processing for content) is performed between the display device 2 and the content providing device 4 (step 24).

  After the payment is made in this way, for example, the display device 1 receives permission information indicating disclosure permission from the content providing device 4, and the disclosure control unit 154 generates screen information for transfer by displaying control information indicating disclosure permission. Notification to the unit 153. The subsequent processing is the same as the processing when the disclosure level is “disclosure” (steps 7 and 8).

(5) In the case of “alternative image” When the disclosure level is “alternative image”, content that is an alternative to the content displayed on the display device 1 (for example, content such as another image that promotes the content) is displayed. Displayed on the display device 2. Processing in this case will be described with reference to FIG. In the process shown in FIG. 8, the process after step 6 is different from the process shown in FIG.

  When it is determined in step 6 that the control corresponding to the “substitute image” is performed, the disclosure control unit 154 transmits a substitute image information request (including content identification information) to the content providing apparatus 4. (Step 31), substitute image information (for example, the substitute image itself or access destination information (URL or the like) to the substitute image) is acquired from the content providing device 4 (step 32). Then, the substitute image information is transmitted to the display device 2 by the content transfer display control unit 15 (step 33).

  If the substitute image information is the substitute image itself, the display device 2 displays the substitute image. If the substitute image information is access destination information to the substitute image, the display device 2 uses the access destination information to acquire and display the substitute image from the content providing device corresponding to the access destination information.

  In the example of FIG. 8, the alternative image information is acquired from the content providing device 4 in steps 31 and 32. Instead of such processing, the alternative image information is included in the content downloaded in step 2. In other words, after the display device 1 acquires and stores the substitute image information in step 2 and decides to perform the substitute image display control in step 6, the substitute image information may be transmitted to the display device 2. Good.

<Second Embodiment>
Next, a second embodiment will be described. In the second embodiment, functions such as the disclosure control unit 154 in the display device 1 described in the first embodiment are provided as a disclosure control server 5 connected to the communication network 3 outside the display device 1. It is a form to be. FIG. 9 shows a functional configuration example of the display device 1 and the disclosure control server 5 in the present embodiment. The disclosure control server 5 may be configured as one function in the content providing device 4, or the disclosure control server 5 and the content providing device 4 may be configured as separate devices.

  The display device 1 according to the present embodiment does not include the disclosure control unit 154 and the disclosure control information storage unit 155 as compared with the display device 1 according to the first embodiment, and the content transfer display control unit 15 A function of communicating with the disclosure control server 5 via the communication network 3 is included. Other functions are the same as those in the first embodiment. However, in the present embodiment, the content acquired from the content providing apparatus 4 includes content identification information, but the disclosure level may not be included.

  The disclosure control server 5 includes a communication unit 51, a disclosure control unit 52, and a content management information storage unit 53. The communication unit 51 is a functional unit for performing data communication via the communication network 3. The disclosure control unit 52 receives content identification information from the content transfer display control unit 15 of the display device 1, refers to the content management information storage unit 53, determines the disclosure control content for the content, and indicates the disclosure control content It has a function of notifying information to the content transfer display control unit 15 of the display device 1.

  An example of a content management table stored in the content management information storage unit 53 is shown in FIG. As shown in FIG. 10, the content management information storage unit 53 stores the disclosure level and the corresponding control content for each content (identification information). The disclosure level and the type of control content here are the same as those described in the first embodiment.

  The basic processing of the system in the second embodiment will be described with reference to FIG.

  First, the display device 1 uses the content acquisition unit 14 to transmit a content request to the content providing device 4 (step 101), and acquires content from the content providing device 4 (step 102). The content acquisition unit 14 that has acquired the content stores the acquired content in the content storage unit 151.

  On the other hand, the display device 2 transmits a screen sharing request to the display device 1 (step 103), and the display device 1 transmits screen sharing permission to the display device 2 (step 104), whereby screen sharing is started. . In the example illustrated in FIG. 11, the screen sharing request is transmitted from the display device 2, and the display device 1 transmits the screen sharing permission to the display device 2. However, the screen sharing request is transmitted from the display device 1. The display device 2 may send a screen sharing permission to the display device 2. Moreover, starting the screen sharing process by transmitting and receiving a screen sharing request and a screen sharing permission is merely an example, and screen sharing may be started by another procedure. The timing for starting screen sharing is arbitrary, and for example, screen sharing may be started before content is downloaded.

  Following step 104, it is assumed that the user of the display device 1 performs an operation for content display. Then, the content display processing unit 152 performs processing for reading the content from the content storage unit 151 and displaying it on the display unit 12 (step 105). This is a normal content display process in the display device 1. On the other hand, as described below, processing for transferring content screen information including non-disclosure processing as necessary is performed.

  The content transfer display control unit 15 reads the content identification information from the content storage unit 151 and transmits it to the disclosure control server 5 (step 106). In the disclosure control server 5, the disclosure control unit 52 refers to the content management information storage unit 53 using the identification information, thereby grasping the disclosure level of the content and determining the disclosure control content corresponding to the disclosure level. Then, the content is transmitted as control information to the display device 1 (step 108).

  The transfer screen information generation unit 153 in the content transfer display control unit 15 that has received the control information creates transfer screen information according to the control information (step 109), and transmits the transfer screen information to the display device 2 (step 109). 110).

  In the present embodiment, the specific processing content of the display device 1 corresponding to each disclosure level is the same as the processing content in the first embodiment.

  The disclosure control server 5 can also be configured to create and transfer screen information for transfer. Hereinafter, this case will be described.

  A functional configuration example of the display device 1 and the disclosure control server 5 in this example is shown in FIG. The configuration illustrated in FIG. 12 is a configuration in which a transfer screen information generation / transmission unit 54 is added to the disclosure control server 5 with respect to the configuration illustrated in FIG. 9.

  Processing in this example will be described with reference to FIG. In the processing shown in FIG. 13, the processing up to step 106 is the same as the processing shown in FIG.

  After step 106, in the disclosure control server 5, the disclosure control unit 52 grasps the disclosure level of the content by referring to the content management information storage unit 53 (FIG. 10) using the identification information, and the disclosure level. The disclosure control content corresponding to is determined, and the content is transferred as control information to the transfer screen information generation / transmission unit 54 (step 111).

  The transfer screen information generation / transmission unit 54 that has received the control information creates transfer screen information in accordance with the control information (step 112), and transmits the transfer screen information to the display device 2 without going through the display device 1. (Step 113).

  For example, if the disclosure level is “disclosure”, the transfer screen information generation / transmission unit 54 transmits the target content to the display device 2 as transfer screen information. The content may be received from the display device 1 in step 106, or the transfer screen information generation / transmission unit 54 may acquire the content from the content providing device 4 using the identification information. Further, what is transmitted to the display device 2 as the transfer screen information may be the content itself, or the same data as the screen data (capture data) displayed on the display device is created and transmitted as the transfer screen information. May be.

  For example, if the disclosure level is “non-disclosure”, the transfer screen information generation / transmission unit 54 generates a mask image or a mosaic image and transmits it to the display device 2 as transfer screen information. Further, the content name (program name or the like) is acquired based on the content identification information, an image in which the name is described on the mask image or the mosaic image is generated, and the generated image is transferred to the display device 2 as screen information for transfer. It is good also as transmitting.

  If the disclosure level is “disclosure for a certain period”, the transfer screen information is transmitted to the display device 2 in the same manner as in the case of “disclosure” from the start of transfer until the predetermined period. When the time has elapsed, the same transfer screen information as in the case of “non-disclosure” is transmitted to the display device 2.

  Further, when the disclosure level is “substitute image”, for example, the transfer screen information generation / transmission unit 54 substitutes image information corresponding to the content identification information (substitute image itself or access destination information to the substitute image ( URL))) is acquired from the content providing apparatus 4 and transmitted to the display apparatus 2 as transfer screen information.

  If the substitute image information is the substitute image itself, the display device 2 displays the substitute image. If the substitute image information is the access destination information of the substitute image, the display device 2 acquires and displays the substitute image from the content providing device corresponding to the access destination information using the access destination information.

  Further, in preparation for the case where the disclosure level is “substitute image”, a substitute image information table in which content identification information and substitute image information are associated with each other as shown in FIG. In addition, when the disclosure level is “substitute image”, the substitute image information may be read from the substitute image information table and transmitted.

  The disclosure control server 5 may first transmit the transfer screen information to the display device 1 instead of transmitting it to the display device 2. In this case, the display device 1 transfers the transfer screen information to the display device 2.

  The disclosure control server 5 can be realized by causing a computer including a CPU, a memory, a communication interface, and the like to execute a program describing processing corresponding to each functional unit. The program can be recorded and distributed on a recording medium such as a portable memory. It is also possible to download the program from a server on the network and install it.

  The present invention is not limited to the above-described embodiments, and various modifications and applications are possible within the scope of the claims. For example, content related to disclosure control and alternative content include not only images (moving images, still images, etc.) but also text information and audio information (speech, music, ringtones, etc.). For example, when the content is music information such as ringtones, only a music intro or a CD jacket image can be used as an alternative content in the disclosure control.
