Description

  The present invention relates to a print control apparatus corresponding to a print service for data broadcasting, and a control method for the print control apparatus.

  As one of data broadcasting services in terrestrial digital broadcasting, a data broadcasting printing service is provided. With this printing service, a user prints information related to a broadcast program, weather forecast, or news information by a printing device (hereinafter referred to as “printer”) connected to a digital television (hereinafter referred to as “DTV”). Print content. In addition, there is a need for broadcast program sponsors to effectively execute advertisements by distributing print contents such as discount coupons and catalogs of products and having the users print them.

Non-Patent Document 1 and Non-Patent Document 2 show digital broadcast standards and operational rules related to this print service. In the printing service based on Non-Patent Document 1 and Non-Patent Document 2, DTV can execute the following three printing modes.
Printing mode 1: A mode in which the DTV acquires print data included in a broadcast wave and requests the printer to print.
Printing mode 2: A mode in which a data broadcast screen being displayed by the DTV is captured and printing is requested from the printer.
Printing mode 3: A mode in which the DTV requests the printer to print the print data existing on the server on the Internet.

The printing form 1 is executed by an extension function included in data broadcast data in an MPEG2 transport stream (hereinafter referred to as “TS”) defined by Non-Patent Document 1 and Non-Patent Document 2. Specifically, the extension function is DOM (Document Object Model) -API (Application Program
Interface) printFile () and printTemplate (). printFile () acquires print data (printFile print data) from the TS obtained by the DTV receiving and demodulating the broadcast wave, and transfers the print data to the printer to make a print request. The print form 2 is executed by printStaticScreen () that is an extended function DOM-API included in the data broadcast data in the TS defined by Non-Patent Document 1 and Non-Patent Document 2. The print mode 3 is executed by printUri () that is an extended function DOM-API included in the data broadcast data in the TS defined by Non-Patent Document 1 and Non-Patent Document 2. printUri () causes the printer to acquire print data (printUri print data) that can be acquired with a URI (Uniform Resource Indicator) specified by the argument, and issues a print request. Normally, printUri print data exists in a content server that exists on the Internet.

  Hereinafter, data broadcast data including the extension functions DOM-API printFile (), printTemplate (), printStaticScreen () and printUri () will be described as “print control data”. In addition to printFile print data, the URI for printUri () is defined as print data. Therefore, the print data included in the broadcast signal refers to the printFile print data and the URI in printUri ().

  In addition, as users' lifestyles diversify, users sometimes record broadcast programs and watch them at their preferred time. For such a purpose, a DTV that incorporates a recording device such as a hard disk and can record a TS is known. However, since the recording device has a limited capacity, the user may be forced to delete, edit, or move the recorded broadcast program data, that is, TS, to another recording device. Therefore, in order to efficiently use the capacity of the recording device, the user may convert and re-record video and audio data included in the recorded TS, or may convert and record at the time of recording. Here, the conversion refers to converting the bit rate of video or audio data or converting the encoding method.

  Further, in Patent Document 1, in order to prevent a recorded program from being erased accidentally while the recorded program is not viewed by the recorder, who of the plurality of viewers on the recorded program list A system capable of displaying whether or not the user has watched is disclosed.

Japanese Laid-Open Patent Publication No. 2005-57637 Japan Radio Industry Association Standards “Data Broadcast Coding and Transmission Methods for Digital Broadcasting” ARIB STD-B24 Japan Radio Industry Association Technical Document “Digital Terrestrial Television Broadcasting Operation Rules” ARIB TR-B14

  Normally, print control data including printFile (), printTemplate () and printStaticScreen () which are extended functions DOM-API, and print data actually transmitted to the printing apparatus exist in the TS. Also, print control data including printUri () that is the extension function DOM-API exists in the TS. Further, print data referred to by printUri exists in a content server existing on the Internet. Therefore, when the user operates the recording device in the DTV and deletes or moves the TS, the print control data and the print data disappear, that is, the print control from the DTV cannot be performed.

  Similarly, if the user edits the TS of the recording device in the DTV and the TS portion including the print control data and the print data disappears, the print control from the DTV cannot be performed. In addition, when the user deletes the print control data or the print data by converting the TS of the recording device in the DTV to another encoding method or the bit rate in order to reduce the data amount, printing from the DTV is performed. It becomes impossible to control.

  In addition, even when the user records TS with another encoding method or by converting the bit rate in order to reduce the data amount, the print control data or the print data may be lost. Cannot perform print control from the DTV. In particular, when printing is not performed, the advertising effect by printing expected by the sponsor of the broadcast program does not increase. In addition, the opportunity to obtain print content useful for the user is lost.

  However, Patent Document 1 does not disclose means for performing display for preventing the user from accidentally erasing print control data and print data included in the TS. Therefore, it is difficult to satisfy the needs of broadcast program sponsors and to prevent losing the opportunity to obtain print content useful for the user.

  The present invention has been made in view of such circumstances. In an apparatus that acquires print data and performs print control processing, the present invention satisfies the needs of print content providers, and the user loses the opportunity to obtain print content. An object of the present invention is to provide a print control apparatus that does not.

  Accordingly, the present invention provides a print control apparatus capable of recording broadcast data including print data generated from a broadcast signal in a recording unit and transmitting the print data to the printing apparatus, the broadcast data recorded in the recording unit Printing based on the print data in response to the user instructing execution of a predetermined control process for the broadcast data determined to contain the print data by the determination means And control means for executing control for notifying the user that it is impossible to execute.

  The present invention also relates to a control method for a print control apparatus capable of recording broadcast data including print data generated from a broadcast signal in a recording unit, and transmitting the print data to the printing apparatus, which is recorded in the recording unit. A determination process for determining whether the broadcast data includes print data, and print data in response to a user instructing execution of a predetermined control process for the broadcast data determined to include print data by the determination process. And a control step of executing control for notifying the user that printing based on the above cannot be executed.

  According to the present invention, when the user instructs execution of a predetermined control process for the broadcast data recorded in the recording unit, if the broadcast data includes the print data, the print data Notify that printing is no longer possible. This notification satisfies the needs of the person who provides the print content, and the user can avoid losing the opportunity to obtain the print content.
