Is not displayed. That is, for example, even if the content D has been downloaded, if the content D is a paid content and the billing process has not been completed, the content D is not presented to the user. . In such a case, for example, by setting “V-” as the attribute value of the Visible attribute of the file attribute information of the content D set by the broadcasting device 10, the content D is completely charged. When it is before, it will not appear in the list.
- step S155 if it is determined in step S155 that the check of the Visible attribute of all DL contents to be displayed in the list has been completed, the content list display process ends.
- the content list display process has been described.
- file attribute information of DL content that is the target of list display is acquired, and information on DL content for which “V +” is set as the attribute value of the Visible attribute is displayed in the list.
- Information regarding DL contents for which “-” is set is not displayed in the list. This makes it possible to switch between display and non-display of information related to DL content in accordance with the operation of the NRT service, so that various operation modes can be flexibly provided.
- step S211 the controller 101 determines whether or not the charging process for the downloaded paid DL content has been performed. If it is determined in step S211 that the charging process for the DL content has been performed, the process proceeds to step S212.
- step S212 the file attribute information setting unit 162 changes the attribute value of the Visible attribute of the file attribute information from “V ⁇ ” to “V +” for the DL content determined to have been charged in step S211. To do. Thereby, for example, for the paid content D, the attribute value of the Visible attribute of the file attribute information is changed from “V ⁇ ” to “V +”.
- the contents A, B, C, and E are displayed on the screen of the television receiver 30 as a list of contents as shown in FIG.
- the content D for which the accounting process has been completed is also displayed.
- the user can play the downloaded content D at the same time as the accounting process is completed without noticing that the content D has been downloaded in advance. If the download of the content D can be started only after the billing process is finished, the content D is not necessarily the target of distribution at the timing of the charge, and has been the target of distribution. However, if the download is started from that point, it takes a certain amount of time until it becomes reproducible, which makes the user feel inconvenient.
- the attribute value of the Visible attribute of the target DL content is changed from “V ⁇ ”.
- the information is changed to “V +” and the information is displayed in the list so that the downloaded content is immediately reproduced.
- the first file attribute information change process has been described as being executed at the timing when the charge process of the charged DL content is performed.
- the charge process is the first file attribute information change process. This is an example of processing that is a trigger for execution, and may be executed at a timing when processing other than billing processing is performed.
- the Visible attribute has been described as the file attribute information to be changed, but the attribute values of the Read attribute and Write attribute may be changed.
- the attribute value of the Read attribute of the target DL content is changed from “R-” to “ It is also possible to change to “R +”.
- the paid DL content is displayed in the content list but cannot be reproduced even before the accounting process is performed, and can be reproduced when the accounting process is completed.
- the first file attribute information change process has been described above.
- the file attribute information change process may be executed in response to execution of a script described in the data broadcasting application.
- the data broadcasting application is an application program for data broadcasting that is executed in conjunction with content such as a television program.
- the data broadcasting application is transmitted by broadcast waves or acquired from a predetermined server (not shown) connected to the Internet.
- step S251 the controller 101 executes the data broadcasting application at a predetermined timing during the reproduction of the DL content.
- step S252 the controller 101 determines whether or not an instruction to change file attribute information is given by executing a script described in the data broadcasting application. If it is determined in step S252 that the change of the file attribute information is not instructed, the determination process is repeated.
- step S252 determines whether the target DL content file is within the management range.
- the determination process is performed by storing the DL content file in a directory for each broadcasting station that performs NRT broadcasting when the DL content file is stored in the storage 106.
- the file attribute information setting unit 162 is a file in which the file instructed to change the setting contents of the file attribute information is stored in a hierarchy lower than the directory hierarchy of the broadcasting station that provides the data broadcasting application. Whether the file is within the management range is determined depending on whether it exists. In other words, only within a predetermined management range determined by the provider of the data broadcasting application provider and the provider of the file provider instructed to change the setting contents of the file attribute information by the data broadcasting application. The setting contents of the file attribute information can be changed.
- management range determination processing is merely an example, and other methods may be employed.
- step S253 the file attribute information setting unit 162 acquires the attribute value specified for each file by the argument of the script function.
- the attribute value is specified as, for example, chmod (file, 7).
- chmod file, 7
- a file whose file attribute information is to be changed is designated as the first argument
- a numerical value corresponding to the above-described three-digit notation using the attribute bits is designated as the second argument.
- R +”, W +”, and “V +” are set as attribute values of the Read attribute, Write attribute, and Visible attribute, respectively.
- step S255 the file attribute information setting unit 162 sets the acquired attribute value to each attribute of the file attribute information of the target DL content.
- step S253 if it is determined in step S253 that the target DL content file is out of the management range, the process proceeds to step S256.
- step S256 the file attribute information setting unit 162 notifies an error indicating that the file attribute information setting change has failed.
- step S255 or S256 When the process of step S255 or S256 is finished, the file attribute information change process is finished.
- the setting content of the file attribute information is changed according to the attribute value specified for each file by the argument of the script function described in the data broadcasting application. Accordingly, the setting contents of the file attribute information can be changed as appropriate according to the operation mode of the NRT service, so that various operation modes can be flexibly provided.
