[Explanation of Operation] Next, the operation of the program type identification processing executed by the display information generating apparatus 100 will be described.

FIG. 7 is a diagram showing a flow of the program type identification processing. The program type identification process may be performed periodically (for example, once a second, once at a predetermined time longer than that, or once at a predetermined time shorter than that, or at a cycle of FIG broadcast frequency, for example. ) Started.

First, the program type identification unit 122 reads the FIC from the transmission frame received from the antenna 50 of the display information generating device 100 (step S001).

Then, the program type identification unit 122 extracts a plurality of FIBs from the FIC (step S002).

Then, the program type identification unit 122 extracts a plurality of FIGs from the FIB (step S003).

Then, the program type identification unit 122 reads the definition of the Program Type by the predetermined FIG and identifies the program type (step S004).

The above is the flow of the program type identification processing. According to the program type identification processing, it is possible to appropriately obtain the program type information from the DAB and identify the program type.

FIG. 8 is a diagram showing a flow of the output information generation processing. The output information generation process is started when the display information generation device 100 starts receiving the DAB.

First, the reception control unit 121 receives DL data and DL plus tag data (step S101). Specifically, the reception control unit 121 extracts the DL data included in the received DAB transmission frame and the DL plus tag data.

Then, the output information generation unit 124 specifies the number of items to be extracted from the DL data according to the display device (step S102). Specifically, the output information generating unit 124 specifies the number of items to be displayed according to the display capability of the display device 200 specified by the necessary information specifying unit 123. For example, the output information generation unit 124 specifies the number of items to be extracted as “2” when the display device 200 has a display area of two lines.

Then, the output information generation unit 124 specifies priority display tags of the number of items to be extracted in order of priority (step S103). Specifically, the output information generation unit 124 specifies the program type 132A of the priority information storage unit 132 by using the information of the program type specified by the program type specification process for the number of items to be extracted specified in step S102. DL plus tags are specified in descending order of priority.

Then, the output information generation unit 124 extracts the DL plus object text of the priority display tag using the data of the DL plus tag (step S104). Specifically, the output information generation unit 124 is designated by the DL plus tag from the DL data using the offset information and the length information included in the DL plus tag for the priority display tags in the order specified in step S103. The text information of the range is extracted as DL plus object text.

Then, the output information generation unit 124 generates output information using the extracted DL plus object text (step S105). Specifically, the output information generation unit 124 uses the DL plus object text extracted in step S104 to generate display information that can be displayed on the display device 200, and stores the display information in the output information storage unit 133. The stored output information is transferred to the storage unit 230 of the display device 200 via the connection establishing unit 222, and the display control unit 221 reads the output information storage unit 231 of the storage unit 230 and controls the display.

The above is the flow of the output information generation processing. According to the output information generation processing, the amount of text information that can be displayed on the display device 200 is appropriately extracted from the DL data according to the type of content, and the display information is appropriately generated as text on the display device 200. Can be output.

FIG. 9 is a diagram showing a specific example of generating the DL plus object text. The received DL data 400 has 43 characters including spaces, and the content is “Now Playing: Sing For The Moment by Enimen.”. Of these, the "Now Playing :" part is a fixed phrase for explaining the content being reproduced, and the "Sing For The Moment" part is the title information of the song. The "Enimen" part is the artist information.

In the information of the attached DL plus tag, the tag having the tag name “Item.title”, which is the first priority DL tag, is described, and “13” that specifies the “start marker”, that is, the start offset position. And "length marker", that is, the information that the length of the title information from the start offset position is "19" is included.

Further, in the information of the attached DL plus tag, a tag having a tag name of “Item.artist”, which is a second priority DL tag, is described, and “start marker”, that is, a start offset position is specified. 36” and “length marker”, that is, information that the length of the artist information from the start offset position is “6” is included.

Here, when the number of lines that can be displayed as text on the display device 200 is two, both the first priority DL tag and the second priority DL tag are used by the output information generation unit 124, and “1” is used as the title, respectively. "Sing For The Moment" and "Enimen" as an artist are read as DL plus objects from the offset information, and each is displayed as text on the first and second lines of the display device 200. The program type is assumed to be "Jazz music (0x18)".

When the number of lines that can be displayed as text on the display device 200 is 1, the output information generation unit 124 uses the first priority DL tag, and “Sing For The Moment” is DL plus from the offset information as the title. It is read as an object and displayed as text on the first line of the display device 200.

However, the present invention is not limited to this. For example, instead of specifying the item to be displayed from the received information of the DAB, the CDC (Compact Disc Data Base) information or the like is read by searching the TOC (Table Of Contents) of the CD to search for the content genre. A display item that matches may be acquired. By doing so, it is possible to easily obtain appropriate information regarding the content regardless of the acquisition route of the content.

The above is the display information generation system according to the first embodiment. According to the first embodiment, it can be said that the display information can be appropriately generated.

However, the present invention is not limited to the above embodiment. The first embodiment described above can be variously modified within the scope of the technical idea of the present invention.

For example, in the first embodiment, the display information generating device 100 and the display device 200 are separate devices, but the present invention is not limited to this, and an integrated device may be used. It may be implemented by a distributed type device in which casings are finely divided according to functions and wireless communication such as Bluetooth (registered trademark) or Wifi (registered trademark) is adopted for mutual communication.

The present invention has been described above with reference to the embodiments. However, the present invention is not limited to this, and the characteristic processing described in the above embodiments may be applied to another device (for example, applied to a detachable smartphone, a mobile terminal such as a tablet device, or the like).
