When the output control unit 1024 detects access to the non-contact IC card reader 1026 during the reproduction of the content information, the control information storage unit 1023 displays the non-contact IC provision information associated with the identifier of the content information being reproduced at that time. The non-contact IC provision information is given to a device (such as Osaifu-Keitai (registered trademark)) that has read the content table stored in the transmission content table and accessed the non-contact IC card reader 1026. The device that has accessed the non-contact IC card reader 1026 obtains data such as a URL of a homepage related to the content information being reproduced, a map of the store, and coupons and points that can be used at the store.

  According to the present embodiment described above, by providing information to digital signage using terrestrial digital broadcast waves, communication costs can be reduced as compared to information provision via a conventional network.

  In addition, since the content information is transmitted by the SDTV at the time of multi-organization broadcasting, the broadcasting station can provide a service for digital signage at the same time while performing normal broadcasting.

  Further, since the content information received by the digital signage 1020 is held in the storage means, even when the digital signage repeatedly reproduces the same content, the broadcast wave does not need to be repeatedly transmitted, and the content is efficiently transmitted. be able to. Also, by holding the content in the storage means, it is possible to play back the content with a different playback schedule for each digital signage.

  Also, even if the same broadcast wave is sent to multiple digital signage, each digital signage selectively acquires only the necessary content according to the broadcast schedule, so select the content to be played back for each digital signage can do.

  Also, since the broadcast schedule is sent from the information transmission means and set in the digital signage, there is no need to input the broadcast schedule on the digital signage side.

  In addition, since each digital signage reproduces content according to an individual reproduction schedule, the content can be reproduced at an appropriate timing for each digital signage.

  Since the reproduction schedule is sent from the information transmission means and registered in each digital signage, the operation of inputting the reproduction schedule on the digital signage side is unnecessary.

  In addition, since information linked to the content being reproduced is given to the user through the non-contact IC card reader, the user can be given an incentive to use digital signage.

    [Acquisition of Content Entity Data: Modification of First Embodiment]

  In the first embodiment, the transmission content table (list) of FIG. 15 is passed from the information transmission means to the digital signage prior to the transmission of the content information, but other embodiments are also conceivable.

  For example, a broadcast schedule of contents to be acquired for each digital signage may be set manually. If data corresponding to the transmission schedule table is registered in the control information storage means of the digital signage, the same information acquisition operation and information reproduction operation as in the first embodiment described above can be realized.

  Further, for example, the first row of data in the sending content table of FIG. 15 is sent out without passing all of the sending content table (list) of FIG. 15 to the digital signage at the same time. Send out the corresponding content information, then send out the data in the second row of the sending content table, and then send out the content information corresponding to the data in the second row, etc. And content information may be sent alternately. In this way, it is not necessary for digital signage to store the entire content table to be transmitted, so that the storage area of digital signage can be saved.

    [Acquisition of Content Entity Data: Second Embodiment]

  Next, a second embodiment of the present invention will be described. Since the entire configuration of FIG. 12 is the same as that of the first embodiment, description thereof is omitted.

  FIG. 13 is a configuration diagram of the broadcasting system 1010A. In the present embodiment, the broadcast wave generating means 1013 sends both content information and control information on the data broadcast band. FIG. 17 illustrates a state in which both content information and control information are placed on the data broadcast band. Data broadcasting data is described in BML. Content information is embedded as mono media in the BML description and transmitted in the data broadcasting band. The content information may be divided and embedded. In this case, in order to combine the divided content information on the digital signage 1020 side, a link is set between each BML file of the divided content information. Alternatively, a common content information identifier is added to each BML file of the divided content information. In addition, in order to transmit the content information and the control information in association with each other, a link is set between both BML files. Alternatively, a common content information identifier is added to both BML files.

  Here, when the broadcasting station simultaneously performs both normal broadcasting and provision of information for digital signage, both data broadcasting data are mixed in the data broadcasting band. In such a state, the digital signage 1020 needs to extract only the data broadcast data transmitted to the digital signage 1020. There are several possible methods for this.

  One is a method of inserting a unique statement (tag) into BML. BML is described by the specifications of XML (Extensible Markup Language) / XHTML (Extensible HyperText Markup Language), but when a unique tag is inserted into BML, a general BML browser ignores tags that cannot be understood by the system. There are features. Therefore, a unique tag is added to the data for digital signage, and the BML browser mounted on the digital signage 1020 has a function to identify the unique tag and determine that the data is for digital signage. Add In this way, even when data broadcast data transmitted from a broadcasting station is received by a device other than the digital signage 1020 of the present embodiment, the operation is affected by ignoring the unique tag. On the other hand, when the digital signage 1020 of this embodiment receives the unique tag, the BML browser to which the function is added is data for the digital signage 1020 based on the unique tag. Can be identified and data can be acquired.

  Similarly, instead of inserting a unique tag, by adding an attribute to the tag and expanding the tag, it is possible to identify the data for the digital signage 1020. When a unique attribute name is added to a tag, a general BML browser has a feature of ignoring it as an instruction that cannot be understood. Therefore, a tag including a unique attribute name is added to the data for the digital signage 1020, and at the BML browser side mounted on the digital signage 1020, the unique attribute name is identified to be data for the digital signage. A function is added so that can be determined. Even if it does in this way, the effect similar to the above can be acquired.

  As another method, a method using an ECMAScript “function for acquiring remaining capacity” in BML can be considered. As a hidden function of this function, it is known that a magic number indicating a receiver manufacturer, a receiver manufacturing date, a BML browser version, and an ECMAScript engine version can be acquired. Using this function, it is possible to determine whether or not the receiver is a digital signage 1020. By branching the BML processing according to the determination result, the digital signage 1020 receives data for digital signage. The data can be acquired and other devices can acquire data for each device. Even if it does in this way, the effect similar to the above can be acquired.

  Next, FIG. 15 is a transmission content table introduced in the first embodiment. In the second embodiment, both control information and content information are transmitted in the data broadcast band. By associating the line data with the corresponding content information, this transmission content table may be omitted. It is assumed that the subsequent control information includes data for one row of the transmission content table. However, there is no need for broadcast schedule data.

  FIG. 16 is a configuration diagram of the digital signage 1020. In this embodiment, the information acquisition unit 1021 acquires both content information and control information from data of data broadcasting, and stores them in the content information storage unit 1022 and the control information storage unit 1023, respectively. The content information and control information are stored in an associated state by adding a link between files or a content information identifier common to the files.

  When acquiring the control information and content information, the information acquisition unit 1021 selects and acquires only the data for digital signage by determining the BML tag or function described above.

  In addition, the information acquisition unit 1021 determines the reception terminal identifier included in the control information at the time of acquisition, and selects and acquires only the control information and content information whose terminal identifier matches the terminal identifier of the own device.

  The output control unit 1024 monitors the reproduction schedule of content information included in the control information stored in the control information storage unit 1023. When a playback schedule arrives for certain content information, the output control unit 1024 reads content information associated with the playback schedule from the content information storage unit 1022 and outputs an output device (such as a display unit 1025 or an audio output device) according to the playback schedule. To play. In addition, the operations of the output control unit 1024, the display unit 1025, and the non-contact IC card reader are the same as those in the first embodiment.

  According to the second embodiment described above, in addition to the same effects as the first embodiment, both content information and control information are transmitted in the data broadcast band, so the broadcasting station is broadcasting HDTV Even when all channels are used for normal broadcasting on SDTV during multi-organization broadcasting, information can be sent for digital signage.
