The terminal device  2  is, for example, a smartphone or a tablet personal computer. 
         [0017]    As shown in  FIG. 2 , the digital signage device  1  includes a controller  11 , a display unit  12 , an input unit  13 , a communication unit  14 , and a storage unit  15 , and the storage unit  15  includes an image data storage unit  151  and an audio data storage unit  152 . 
         [0018]    The controller  11  is constituted by a Central Processing Unit (CPU) and the like and includes the CPU that executes various programs stored in the storage unit  15  to perform predetermined calculation and control each unit and a memory serving as a working area when the programs are executed (both are not shown). 
         [0019]    The display unit  12  is a projector that converts image data output from the controller  11  into projected light to irradiate a screen with the projected light. 
         [0020]    For example, as a projector, it is possible to apply a Digital Light Processing (DLP) (registered trademark) projector including a digital micromirror device (DMD) which is a display element that performs display operation by turning on/off individual inclination angles of a plurality of (in the case of XGA, horizontal 1024 pixels×vertical 768 pixels) micromirrors arranged in an array at a high speed and forms an optical image with the use of reflected light thereof. 
         [0021]    The input unit  13  accepts content change operation and the like from a user. The communication unit  14  transmits and receives a radio signal based on the BLE via an antenna (not shown). The communication unit  14  broadcasts a Beacon (advertise) based on the BLE, receives a connection request transmitted from the terminal device  2  in response to the Beacon, then establishes connection, and receives language information from the terminal device  2 . 
         [0022]    The storage unit  15  includes the image data storage unit  151  storing image data to be projected and the audio data storage unit  152  storing audio data to be output in accordance with the image data. The audio data storage unit  152  stores a plurality of pieces of audio data of languages in various countries, such as Japanese, English, and Chinese, corresponding to image data. 
         [0023]      FIG. 3  is a block diagram of a configuration of the terminal device  2 . The terminal device  2  includes a controller  21 , a display unit  22 , an input unit  23 , a communication unit  24 , and a storage unit  25 , and the storage unit  25  includes a language information storage unit  251 . 
         [0024]    The controller  21  is constituted by a Central Processing Unit (CPU) and the like and includes the CPU that executes various programs stored in the storage unit  25  to perform predetermined calculation and control each unit and a memory serving as a working area when the programs are executed (both are not shown). 
         [0025]    The display unit  22  includes, for example, a Liquid Crystal Display (LCD) or an Electroluminescence (EL) display. 
         [0026]    The input unit  23  is, for example, a touchscreen, is provided on the display unit  22 , and is an interface used for inputting content of operation performed by a user. The touchscreen includes, for example, a transparent electrode (not shown). In the case where a finger or the like of a user is touched, the touchscreen detects a position where a voltage is changed as a touch position and outputs information on the touch position to the controller  21  as an input instruction. 
         [0027]    The storage unit  25  includes the language information storage unit  251  storing language information used by a user. 
         [0028]      FIG. 4  shows a sequence of wireless communication for acquiring language information according to this embodiment. 
         [0029]    First, the digital signage device  1  broadcasts a Beacon with the use of the communication unit  14  (Step S 41 ). The Beacon contains identification information of the digital signage device  1 . 
         [0030]    Then, the terminal device  2  that has received the broadcasted Beacon specifies the digital signage device  1  on the basis of the identification information contained in the Beacon and transmits a connection request to the digital signage device  1  (Step S 42 ). 
         [0031]    The digital signage device  1  that has received the connection request establishes communication with the terminal device  2 , and the terminal device  2  acquires used language information from the language information storage unit  251  and transmits the language information to the digital signage device  1  (Step S 43 ). 
         [0032]      FIG. 5  is a flowchart of content output processing of the digital signage device  1 . The digital signage device  1  refers to the image data storage unit  151  and projects a content. The digital signage device  1  acquires audio corresponding to the content from the audio data storage unit  152  and reproduces the audio. 
         [0033]    First, the digital signage device  1  broadcasts a Beacon (Step S 51 ). The digital signage device  1  determines whether or not a connection request has been received from the terminal device  2  in response to the Beacon broadcasted in Step S 51  (Step S 52 ). 
         [0034]    In the case where the connection request has not been received (Step S 52  NO), the processing returns to Step S 51  and the digital signage device  1  broadcasts a Beacon again. In the case where the connection request has been received (Step S 52  Yes), the digital signage device  1  establishes connection with the terminal device  2  (Step S 53 ). 
         [0035]    After connection with the terminal device  2  is established, the digital signage device  1  determines whether or not language information has been received from the terminal device  2  (Step S 54 ). In the case where it is determined that the language information has not been received (Step S 54  NO), Step S 54  is repeated until the language information is received. 
         [0036]    In the case where the language information has been received (Step S 54  YES), the digital signage device  1  compares language information of audio that is currently reproduced with the language information transmitted from the terminal device and determines whether or not those pieces of language information match with each other. 
         [0037]    In the case where those pieces of language information match, reproduction is continued. In the case where it is determined that those pieces of language information do not match, the processing proceeds to Step S 56 , and the digital signage device  1  changes the language by referring to the audio data storage unit  152  to acquire audio data matching with the language information transmitted from the terminal device and reproducing the audio data. 
         [0038]      FIG. 6  is a flowchart of content output processing of the terminal device  2  according to this embodiment. 
         [0039]    The terminal device  2  determines whether or not a Beacon has been received from the digital signage device  1  (Step S 61 ). In the case where it is determined that the Beacon has not been received (Step S 61  NO), Step S 61  is repeated until the Beacon is received. 
         [0040]    In the case where it is determined that the Beacon has been received in Step S 61 , the terminal device  2  specifies the digital signage device  1  that has transmitted the Beacon on the basis of identification information contained in the Beacon, transmits a connection request to the digital signage device  1  (Step S 62 ), and establishes connection with the digital signage device  1 . 
         [0041]    After transmitting the connection request to the digital signage device  1 , the terminal device  2  refers to the language information storage unit  251  to acquire a language set as a used language. After the used language is acquired, the terminal device  2  transmits language information on the used language to the digital signage device  1  (Step S 63 ). 
         [0042]    As described above, in this embodiment, the digital signage device  1  changes a language by acquiring language information from the terminal device  2 . Therefore, it is possible to reproduce a content suitable for each user. 
         [0043]    In this embodiment, only audio data is changed and image data is not changed. However, this embodiment is not limited thereto, and moving image data in which image data and audio data are integrated may be changed. 
         [0044]    In the case where there is no audio data matching with language information acquired from the terminal device  2 , audio data may be changed to audio data of a language which is likely to be understood, i.e., audio data may be set to, for example, English. 
         [0045]    The embodiment described above is presented merely as an example and does not intend to limit the gist of the invention. The above new embodiment can be implemented in other various forms, and various kinds of omission, replacement, and modification can be performed within the scope of the invention.
