(S812). On the other hand, if the confirmation result (S810), the digital information display device 120 is not reconnected through short-range communication, the user terminal 110 performs a process S810 to determine whether or not reconnected through the short-range communication.

In operation S814, the user terminal 110 may download and update the updated digital information item from the service providing apparatus 130, or may download the digital information based on the download address information and update the previously downloaded digital information.

Subsequently, the user terminal 110 may display the updated digital information to the user by executing an application corresponding to the updated digital information item (S816).

On the other hand, the above-described digital information synchronization method between the digital information display and the user terminal may be implemented in a software program and recorded in a computer-readable predetermined recording medium.

For example, the recording medium may be a hard disk, a flash memory, a RAM, a ROM, or the like as an internal type of each playback device, or an optical disc such as a CD-R or a CD-RW, a compact flash card, a smart media, a memory stick, or a multimedia card as an external type. have.

In this case, a program recorded on a computer-readable recording medium includes a digital information display process in which a digital information display device receives digital information related to a public place from a service providing device to display digital information, and the digital information display device and the user. A short-range communication connection process in which a terminal is connected through short-range communication, wherein the digital information display device requests the service providing apparatus to digitally synchronize the displayed digital information according to a digital information synchronization request of a user terminal connected through the short-range communication. An information synchronization request process, a digital information receiving process of receiving, by the user terminal, digital information from the service providing apparatus in response to the digital information synchronization request, and displaying the same to the user; Value and the user terminal is reconnected through short-range communication, the digital information update process of transmitting the updated digital information to the user terminal compared to the digital information transmitted to the reconnected user terminal, the user, and the user The terminal may include the update information display process of displaying the updated digital information received from the service providing apparatus to the user.

On the other hand, the program recorded on the computer-readable recording medium, the information providing process for providing digital information related to the public place to a digital information display device installed in a public place, request the digital information synchronization of the user terminal from the digital information display device The digital information transmission process of transmitting digital information to the user terminal upon receiving the digital information, and if the digital information synchronization of the reconnected user terminal is requested from the digital information display apparatus through short-range communication, whether to update the digital information previously transmitted to the user terminal. An update confirmation process for confirming and an update digital information transmission process for transmitting updated digital information to the user terminal as a result of the update confirmation may be executed.

On the other hand, a program recorded on a computer-readable recording medium is installed in a public place, the digital information receiving process for receiving and displaying digital information related to the public place from the service providing device, the user terminal and the short-range communication by connecting to the user An information receiving process of receiving digital information items and terminal information to be digital information synchronization targets from a terminal, an information synchronization request process of transmitting the received digital information items and terminal information to a service providing device and requesting digital information synchronization; and If the user terminal is reconnected through short-range communication, the terminal may include a terminal reconnection process of transmitting the terminal information of the reconnected user terminal and the selected digital information item to the service providing apparatus.

Functional operations and implementations described in the specification of the present invention may be implemented in digital electronic circuitry, computer software, firmware or hardware, or a combination of one or more of them. Implementations described in the specification of the present invention are one or more modules relating to computer program instructions encoded on a program storage medium of tangible type for controlling or by the operation of one or more computer program products, ie data processing apparatuses. It can be implemented as.

While the drawings of the present invention describe an operational process, it should not be understood that such operations must be performed in the specific order shown or that all illustrated operations must be performed in order to obtain desirable results. In certain cases, multitasking and parallel processing may be advantageous.

In addition, specific embodiments have been described in the specification of the present invention. Embodiments are within the scope of the following claims. For example, the actions recited in the claims can be performed in a different order while still achieving desirable results.

The above description is merely illustrative of the present invention, and various modifications may be made by those skilled in the art without departing from the technical spirit of the present invention. Therefore, the embodiments disclosed in the specification of the present invention are not intended to limit the present invention. The scope of the present invention should be construed by the claims below, and all techniques within the scope equivalent thereto will be construed as being included in the scope of the present invention.

According to the present invention, digital information displayed on a digital information display device installed in a public place is received and displayed to a user according to a digital information synchronization request of a user terminal, and the user terminal revisits the public place and displays the digital information display device. When reconnected with the mobile station, the updated digital information may be automatically synchronized with the service providing device. In this respect, the invention is a commercially available invention because the possibility of marketing or operating the applied device is not only sufficient for the use of the related technology, but also practically evident as it exceeds the limitation of the existing technology.
