However, each time the related information Q presented on the selection screen 60 is selected, A configuration in which the terminal device 16 acquires the content C corresponding to the information Q from the distribution device 12 may also be employed. In addition, when the identification information D is received from the information transmission device 14, the terminal device 16 acquires a plurality of contents C whose location information W includes the identification information D from the distribution device 12, and the user selects from the selection screen 60. It is also possible to reproduce the content C corresponding to the related information Q. The present invention can also be applied to the case where the content C is distributed from the distribution device 12 to the terminal device 16 by the streaming method. Further, in the configuration in which the content C is distributed from the distribution device 12 to the terminal device 16 in advance, the content C corresponding to all the exhibits P in the exhibition facility M is transmitted to the terminal device 16 collectively. A configuration in which contents C of a plurality of exhibits P included in some exhibition rooms A in the exhibition facility M are transmitted to the terminal device 16 or contents C of a plurality of exhibits P in one exhibition room A The structure transmitted to the terminal device 16 can also be suitably employed.

(3) In each of the above-described forms, as an example of an aspect in which the related information Q of the content C is preferentially presented, a configuration in which the user can easily view the information is displayed above the selection screen 60 of the display device 542. Although illustrated, the display mode for presenting specific related information Q preferentially is not limited to the above examples. For example, as illustrated in FIG. 10, the related information Q of the content C that is preferentially presented in the exhibition room A may be highlighted.

(4) In the above-described embodiments, the reproduction of the content C starts when the content C desired to be reproduced is selected from the related information Q (image G) of the plurality of contents C displayed on the display device 542. 11, the indicator V (V1 to V3) instructing the start of reproduction is displayed adjacent to the related information Q, for example, as illustrated in FIG. A configuration may be adopted in which a desired content C is reproduced by receiving an operation of pressing the indicator V from the user.

(5) Among the plurality of exhibition rooms A (A1, A2) in the exhibition facility M, it is possible to preferentially present the related information Q of the exhibit P in the specific exhibition room A. Specifically, as illustrated below, a configuration in which the related information Q of the exhibit P in the exhibit room A having a low degree of congestion among the plurality of exhibit rooms A is preferentially presented is preferable.

  The distribution apparatus 12 calculates the congestion degree α for each of the plurality of exhibition rooms A in the exhibition facility M. The congestion degree α of each exhibition room A is an index indicating the degree of congestion in the exhibition room A. Various methods can be employed for calculating the congestion degree α. For example, every time the identification information D is received from the information transmission device 14, a reception notification including the identification information D is transmitted from the terminal device 16 to the distribution device 12. In the configuration, the distribution device 12 can use as the congestion degree α by counting the number of times the distribution device 12 receives the reception notification from each terminal device 16 for each exhibition room A (for each identification information D). The distribution apparatus 12 notifies the congestion degree α of each exhibition room A to the terminal apparatus 16 that has transmitted the reception notification.

  The control device 42 of the terminal device 16 causes the selection screen 60 to preferentially display the related information Q of the exhibition room A having a low congestion degree α received from the distribution device 12 among the plurality of exhibition rooms A of the exhibition facility M. For example, FIG. 12 illustrates a selection screen 60 when the degree of congestion α1 of the exhibition room A1 of the exhibition room A1 and the exhibition room A2 in the exhibition facility M is less than the degree of congestion α2 of the exhibition room A2. As understood from FIG. 12, when the degree of congestion α1 is less than the degree of congestion α2, on the selection screen 60, the related information Q of each exhibit P in the exhibition room A1 is related information of each exhibit P in the exhibition room A2. It is displayed preferentially (specifically, above the selection screen 60) compared to Q. If the related information Q of the exhibit P in the exhibition room A with a low degree of congestion α is preferentially presented as illustrated above, it is possible to guide the user to the exhibition room A with a low degree of congestion.

(6) In each of the above-described embodiments, the identification information D is transmitted to each terminal device 16 by acoustic communication using sound as a transmission medium, but the communication method for transmitting the identification information D is not limited to acoustic communication. For example, the identification information D can be transmitted from the information transmission device 14 to the surroundings by wireless communication using electromagnetic waves such as radio waves and infrared rays as a transmission medium. As understood from the above examples, short-range wireless communication without the communication network 18 is suitable for transmission of the identification information D, and acoustic communication using sound as a transmission medium and wireless communication using electromagnetic waves as a transmission medium are suitable. It is an illustration of near field communication.

  For example, electromagnetic waves such as infrared rays used for wireless communication have high directivity or straightness, whereas sound used for acoustic communication can be propagated over a wide range. The identification information D can be transmitted to 16 in a batch. In addition, in the configuration in which the identification information D is transmitted by acoustic communication, for example, the existing sound emitting device 26 used for broadcasting in the exhibition facility M can be used for transmission of the identification information D, and used for voice calls and recording. The existing sound collecting device 56 can be used for receiving the identification information D. Therefore, there is an advantage that a wireless communication device dedicated to transmission / reception of the identification information D is unnecessary.
