[Outline of output sharing system 1]
FIG. 1 is a diagram for explaining an outline of an output sharing system 1 which is a preferred embodiment of the present invention. The outline of the output sharing system 1 will be described based on FIG.

  The output sharing system 1 includes an output sharing terminal 10 that performs output sharing, a content sharing attribute management server 200, and one or more communication terminals 50.

  First, the output sharing terminal 10 that performs output sharing specifies the content currently being played on the output sharing terminal 10, acquires the content information of the content, and then acquires the content information to acquire the content sharing attribute. Is transmitted to the content sharing attribute management server 200 (step S01).

  Here, output sharing is obtained by expanding screen sharing to various output formats, not limited to image data displayed on the screen. That is, it means that an output such as an image or sound reproduced on the output sharing terminal 10 is transmitted as data to the communication terminal 50, and the communication terminal 50 reproduces it.

  The content information is information related to the content, including metadata such as extension, creator, and copyright information attached to the content, and all of the specified unified resource location specifier (URL) of the specified content. Or it may include a part and the kind of application which is reproducing contents, but it is not restricted to these.

  The content sharing attribute is an optional parameter related to content sharing, such as whether content can be shared or the number of simultaneous shares. The content sharing attribute is set to appropriately share the content for the convenience of the owner of the output sharing terminal 10 such as the viewpoint of privacy, the viewpoint of ownership including copyright, and the viewpoint of confidentiality. . The content sharing attribute is normally managed by the content sharing attribute management server 200, but each user may individually overwrite the setting regarding his / her terminal.

  Upon receiving the content information from the output sharing terminal 10, the content sharing attribute management server 200 extracts the content sharing attribute related to the content from the content sharing attribute management database 250 using the received content information (step S02).

  In FIG. 1, content acquired from two types of URLs is played on the browser of the output sharing terminal 10, and content sharing attributes are extracted from all or part of the two types of URLs. At this time, the most appropriate content sharing attribute is extracted with emphasis on the full path and domain of the URL. Further, the content information in the content sharing attribute management database 250 may be set in a pattern such as a regular expression.

  Then, the content sharing attribute management server 200 transmits the extracted content sharing attribute to the output sharing terminal 10 (step S03). In FIG. 1, a content sharing attribute is set such that content being played back at the top of the screen can be shared, but content being played back at the bottom of the screen cannot be shared.

  The output sharing terminal 10 that has received the content sharing attribute shares each content with the communication terminal 50 based on the content sharing attribute (step S04). In addition, when the output sharing terminal 10 shares all the outputs, such as performing remote control with the communication terminal 50, the output sharing other than the contents may be shared.

Further, in the content sharing attribute management server 200, the control unit 201 reads a predetermined program, thereby realizing the shared attribute extraction module 206 in cooperation with the storage unit 203.

[Output sharing processing]
FIG. 4 is a flowchart of output sharing processing executed by the output sharing terminal 10 and the communication terminal 50. The processing performed by the module of each device described above will be described together with this processing.

  First, the remote control module 16 of the output sharing terminal 10 starts remote control for the communication terminal 50 (step S11). In response to this, the remote control module 54 of the communication terminal 50 also starts remote control (step S12). Note that output sharing is not yet performed at this point, and communication for that purpose may be established. In addition, it is not a requirement of the present invention which one receives the remote control at this time, but it is considered that the output sharing terminal 10 often receives the remote control in view of sharing the output.

  Next, the playback content specifying module 18 of the output sharing terminal 10 specifies the content being played back on the output sharing terminal 10 (step S13). At this time, as an example of specific processing for specifying the content being played back, first, an application that outputs data to an output unit such as a speaker or a screen is specified, and then the external file that is the content is the application. Or whether the application itself is content. By repeating this procedure, the content being reproduced can be specified.

  Note that applications such as a browser, a chat application, a player application, and the like that can play back content or become content itself may be stored as a list or acquired from the content sharing attribute management server 200.

  Next, the content information acquisition module 19 of the output sharing terminal 10 acquires content information of the content being reproduced (step S14). Here, the content information is information related to the content, including metadata such as extension, creator, and copyright information attached to the content, and the unified resource locator (URL) of the specified content. It may include all or part and the type of application that is playing the content, but is not limited thereto.

  Further, as a specific example of the content information acquisition method, a content information acquisition method may be defined for each type of application. For example, if the browser application is running, the page URL is acquired, and all URLs of external files read from the page URL in a format such as a link are acquired. In the case of a player application, the URL of each media file such as music, video, image, storage location, file attribute, etc. are acquired.

  Next, the output sharing terminal 10 executes content sharing attribute acquisition processing together with the content sharing attribute management server 200 in order to acquire the sharing attribute of each content being played back (step S15).

[Content sharing attribute acquisition processing]
FIG. 5 is a flowchart of content sharing attribute acquisition processing executed by the output sharing terminal 10 and the content sharing attribute management server 200. The processing performed by the module of each device described above will be described together with this processing.

  First, the shared attribute acquisition module 14 of the sharing terminal 10 transmits the acquired content information to the content sharing attribute management server 200 for each of the content being played back specified above (step S21).

  The content information receiving module 204 of the content sharing attribute management server 200 receives the content information (step S22), and the shared attribute extraction module 206 extracts the content sharing attribute from the content sharing attribute management database 250 using the received content information. (Step S23).

  FIG. 7 is an example of a content sharing attribute management table in the content sharing attribute management database 250. In the content sharing attribute management table, content information, information type, sharing availability, and sharable number are set. Here, based on the information type and value of the received content information, the availability of sharing and the number of shares that can be shared are extracted. Note that the URL may be set separately for the URL form and the domain name. If both are applicable, priority is given to matching the entire URL. Specifically, such a setting is used when most files in a certain domain can be shared but only specific files cannot be shared.

  Here, the sharable number represents the upper limit of the number that can share each content at the same time. In addition to remote control, applications that share and execute a single screen, such as cooperative and competitive games, can be limited by the number of shares that can be shared. It is also possible to set the number of shares that can be shared indefinitely and not limit by the number.

  Returning to the process, the content sharing attribute extracted by the content sharing attribute transmission module 205 of the content sharing attribute management server 200 is transmitted (step S24), and the shared attribute acquisition module 14 of the sharing terminal 10 receives this (step S25).

  The above is the procedure of the content sharing attribute acquisition process. This process is executed for all of the specified contents being reproduced.

  Returning to the output sharing process, the output sharing module 17 of the sharing terminal 10 transmits the output as data to the communication terminal 50 based on the received sharing attribute of the content (step S16).

  Here, based on the content sharing attribute, for content that can be shared, output is shared as usual, and for content that cannot be shared, the output of the application that is playing the content is excluded from sharing targets. Or forcibly terminating the application itself, or waiting for output sharing until the user terminates the application. In this process, if a part corresponding to the content in the output of the application can be specified, only a part of the output of the application can be excluded from the sharing target.

  Even if the content can be shared, the content exceeding the sharable number is handled in the same manner as the content that cannot be shared. Further, the output other than the content may be transmitted as it is.

  Finally, when the output data receiving module 55 of the communication terminal 50 receives the shared output data (step S17), the output data output module 56 outputs the output data (step S18).

  FIG. 6 is an example of the output of the output sharing terminal 10 and the communication terminal 50 that are performing output sharing. In FIG. 6, the output sharing terminal 10 displays the browser application in full screen and reads the content specified by the URL 61. Further, an embedded video 62 and an image link 63 are set for the content that is a web page.

  Here, as a result of the output sharing terminal 10 acquiring the sharing attribute of each content, the moving image 62 can be shared, but the image used as the image link 63 is acquired from another domain and cannot be shared. Suppose. In this case, the embedded moving image 64 is output as the output of the communication terminal 50, but the image of the image link 65 is excluded from sharing targets.

  With the above processing, it is possible to appropriately share the output of the content being played on the output sharing terminal 10 based on the sharing attribute. The above is the procedure of the output sharing process.

  The means and functions described above are realized by a computer (including a CPU, an information processing apparatus, and various terminals) reading and executing a predetermined program. The program is provided in a form recorded on a computer-readable recording medium such as a flexible disk, CD (CD-ROM, etc.), DVD (DVD-ROM, DVD-RAM, etc.), for example. In this case, the computer reads the program from the recording medium, transfers it to the internal storage device or the external storage device, stores it, and executes it. The program may be recorded in advance in a storage device (recording medium) such as a magnetic disk, an optical disk, or a magneto-optical disk, and provided from the storage device to a computer via a communication line.
