For identifying each of the plurality of insertion phrases.

3 is configured by a processing device such as a CPU (Central Processing Unit), and controls the overall operation of the information generation system 300. Specifically, when the control device 31 executes a program stored in the storage device 33, a plurality of functions (a generation unit 312 and a signal for generating and distributing the distribution data Q are exemplified as illustrated in FIG. 3). A processing unit 314) is realized.

The generation unit 312 generates distribution data Q for the terminal device 400 to present the related information R related to the display information I to the user U from the display data W transmitted from the display control system 100. That is, the display data W for displaying the display information I on the display device 23 is also used for generating the distribution data Q. The distribution data Q is identification information for identifying a character string representing the related information R, and more specifically, the fixed phrase information DA representing the fixed phrase of the related information R and the inserted phrase information DB representing the insertion phrase of the related information R. Including. That is, the generation unit 312 identifies the fixed phrase information DA and the plurality of insertion phrase information DB corresponding to the display information I represented by the display data W, and the distribution data Q including the fixed phrase information DA and the insertion phrase information DB is obtained. Generate.

Specifically, the generation unit 312 first specifies an insertion phrase from the display information I obtained by analyzing the display data W, and acquires insertion phrase information DB corresponding to the specified insertion phrase from the insertion phrase information table TB1. . For example, display information I1 (11:27), display information I2 (express), display information I3 (Shibuya), display information I4 (second line), display information I5 (Ikebukuro), and display information I6 (Shinjuku) When the display data W is transmitted from the display control system 100, the generation unit 312 displays the display information I1 to “11:27”, “Express”, “Shibuya”, “Line 2”, “Ikebukuro”, and “Shinjuku”. I6 is obtained from the analysis of the display data W. The generation unit 312 specifies, for example, the display information I3 “Shibuya” obtained by the analysis as an insertion phrase corresponding to the insertion phrase information table TB1 and corresponds to the specified insertion phrase “Shibuya”. Insertion phrase information DB “205” is acquired. A plurality of insertion phrases can be specified from one display data W. For analysis of the display data W, a known technique can be arbitrarily adopted.

Further, the generation unit 312 acquires the fixed phrase information DA corresponding to the plurality of insertion phrase information DB acquired from the display data W from the fixed phrase information table TA1. For example, when the insertion phrase “express” indicating the type of train and “Shibuya” indicating the station name are identified from the analysis of the display data W, the generating unit 312 determines the fixed phrase “[] line indicating the departure guidance of the train. The next train of [] is [] hour [] minutes, [], [] line. Stop station is [], [].] Boilerplate information DA "101" corresponding to the boilerplate information table TA1 Get from. For example, if the insertion phrase “personal accident” indicating the cause of the delay is identified from the analysis of the display data W, the fixed phrase indicating the train delay guidance “This train is delayed by [] because of [].” The fixed phrase information DA “102” corresponding to is acquired from the fixed phrase information table TA1. The generation unit 312 generates distribution data Q including the fixed phrase information DA and the plurality of insertion phrase information DB specified by the procedure exemplified above. The method for specifying the boilerplate information DA is arbitrary. For example, the phrase information DA corresponding to the plurality of insertion phrase information DB acquired from the display data W is specified with reference to a table in which the phrase information DA and the insertion phrase information DB (or insertion phrase) are registered in association with each other. It is also possible. For example, the fixed phrase information DA can be specified from the display information I obtained by analyzing the display data W.

3 generates an acoustic signal SQ including the distribution data Q generated by the generation unit 312. The signal processing unit 314 illustrated in FIG. The acoustic signal SQ contains the distribution data Q as an acoustic component in a predetermined frequency band. Specifically, the frequency band of the acoustic signal SQ is a frequency band in which sound can be emitted by the sound emitting device 35 and collected by the terminal device 400, and voices that the user U listens in a normal environment and It is included in the range of a frequency band (for example, 18 kHz or more and 20 kHz or less) that exceeds the frequency band of sound such as musical sound. For the generation of the acoustic signal SQ by the signal processing unit 314, a known technique can be arbitrarily adopted. For example, the acoustic signal SQ is generated by frequency-modulating a carrier wave such as a sine wave having a predetermined frequency with the distribution data Q. A configuration in which the acoustic signal SQ is generated by sequentially executing the spread modulation of the distribution data Q using a spread code and the frequency conversion using a carrier wave of a predetermined frequency may be employed. Acoustic watermarking or fingerprinting techniques can also be employed to generate the acoustic signal SQ.

The sound emitting device 35 is an acoustic device (speaker) that emits sound according to the acoustic signal SQ generated by the signal processing unit 314. For example, the sound emitting device 35 can be attached to the display device 23. Therefore, if the user U goes near the display device 23, the terminal device 400 can collect sound corresponding to the sound signal SQ. As understood from the above description, the sound emitting device 35 functions as an element that transmits the distribution data Q to the terminal device 400 by acoustic communication using a sound wave that is air vibration as a transmission medium. According to the configuration in which the distribution data Q is distributed by sound emission from the sound emission device 35, the terminal device 400 does not need a communication device dedicated to wireless communication (for example, short-range wireless communication) using infrared rays or radio waves. Distribution data Q can be distributed. The D / A converter that converts the acoustic signal SQ from digital to analog is not shown for convenience. As understood from the above description, the signal processing unit 314 and the sound emitting device 35 function as the distribution unit 37 that distributes the distribution data Q generated by the generation unit 312 to the terminal device 400.

<Modification>
Each aspect illustrated above can be variously modified. Specific modifications are exemplified below. Two or more modes arbitrarily selected from the following examples can be appropriately combined within a range that does not contradict each other.

(1) In the first embodiment, the language (Japanese) expressing the related information R stored in the storage device 45 of the terminal device 400 is the same as the language (Japanese) expressing the display information I. The language that expresses the related information R stored in the device 45 may be different from the language that expresses the display information I. For example, the language expressing the display information I is Japanese, but the language expressing the related information R stored in the storage device 45 can be English.

(2) In each of the above-described forms, the phrase identification information is exemplified as the phrase information DA and the insertion phrase identification information is exemplified as the insertion phrase information DB. However, the contents of the phrase information DA and the insertion phrase information DB are as follows: It is not limited to the above illustration. For example, a configuration in which the fixed phrase information DA represents the character string of the fixed phrase or a configuration in which the insertion phrase information DB represents the character string of the insertion phrase may be employed. According to the above configuration, there is no need to store the fixed phrase presentation table TA2 and the insertion phrase presentation table TB2 in the storage device 45. On the other hand, according to each of the above-described embodiments in which the fixed phrase identification information is the fixed phrase information DA and the insertion phrase identification information is the insertion phrase information DB, the data amount of the distribution data Q can be reduced.

(3) In each of the above-described embodiments, the related information R is divided into the fixed phrase and the insertion phrase, but a configuration in which the distinction between the fixed phrase and the insertion phrase is omitted may be employed. For example, a plurality of related information R different in terms corresponding to the insertion phrase is prepared in advance, and the related information R specified according to the display data W among the plurality of related information R is distributed as distribution data Q. It is also possible. However, according to each of the above-described forms in which the related information R is classified into a fixed phrase and an inserted phrase, a single fixed phrase is shared for providing a plurality of related information R including different inserted phrases. It is possible to reduce the amount of data necessary for providing the related information R to the terminal device 400.

(4) In each form mentioned above, although the display data W included the text data showing each character string of the some display information I, the structure and kind of the display data W are not limited to the above illustration.
