Here, the service information is information for driving the device 200, and more specifically, information indicating at least one or more types that are activated by driving the device 200.

FIG. 3 is a diagram illustrating an input value for an activation signal type subfield in the format shown in FIG. 2. As shown by way of example only in FIG. 3, the type of activation type is a first type (eg, Pop-UP type) for activating a guidance screen for the initiation of a broadcast service as a pop-up, a broadcast service. Is the second type (eg, Normal type) for activating the service list screen when there are a large number, and the third type (eg, Auto-Execute) for automatically executing the application program corresponding to the broadcast service when there is one broadcast service. Type), and the fourth type for activating the announcement about service unavailable when there is no broadcast service.

4 is a configuration diagram of the device 200 shown in FIG. 1. As shown only as an example in FIG. 4, the device 200 may receive a beacon signal transmitted from the wireless transmission apparatus 100 as it enters a short range area, and then may receive a broadcast service through reception of a beacon signal. The short-range wireless chip unit 210 for generating a service entry event for notifying the entry into the service coverage, which is a beacon after receiving the service entry event generated from the short-range wireless chip unit 210 through the continuously active program. An intermediary program execution unit for determining service information on a broadcast service included in a signal and forming control information for executing the broadcast service on the basis of a service execution route formed by applying the determined result to a preset service reception environment of a user ( 220, and receiving control information from the program execution unit 220 to start the broadcast service through this Or an application program execution unit 230 for displaying a guide screen on the terminal screen or starting an application program for execution of a broadcast service.

In addition, the device 200 further includes an output unit 240 for outputting a broadcast screen through execution of a guide screen or an application program to the terminal screen.

Here, the service reception environment set by the user is preferably set to any one or more of the first to fourth types mentioned above.

The intermediary program execution unit 220 compares the service information and the service receiving environment with each other, and then proceeds with a subsequent process for executing the broadcast service according to the extracted type information by extracting the type information matching each other as a result of the comparison.

If the program execution unit 220 compares the service information and the service reception environment with each other, but there is no matching type information, it is preferable to execute the broadcast service in a preset type as a default.

The type set to default may be set to any one of various types, and hereinafter, the type set to the second type will be described in detail.

FIG. 5 is a flowchart illustrating an operation of a system for driving the device 200 for receiving a broadcast service in the short range region illustrated in FIG. 1. As shown only as an example in FIG. 5, the method of driving the device 200 for receiving a broadcast service in the short range area includes a wireless transmission apparatus after the device 200 enters the short range area or after entering the short range area. As the 100 is reactivated, the process proceeds to receiving the beacon signal transmitted (S1 and S3).

Thereafter, the device 200 recognizes an entry into a service coverage that can receive a broadcast service through reception of a beacon signal, and generates a service entry event due to the recognition (S5 and S7).

After receiving the service entry event, the program execution unit 220 in the device 200 executes a subsequent process to determine service information on the broadcast service included in the beacon signal (S9), and sets the determined information in advance. The comparison is made by applying the service reception environment of the user (S11).

Thereafter, the intermediate program execution unit 220 sets an activation type of the device 200 for executing the broadcast service according to the comparison result (S13).

In step S13, when there is a type matching between the service information and the service receiving environment, the existing type is set as a type for activating the device 200 (S15).

When the type for activating is the first type (that is, the pop-up type), a guide screen for guiding the start of the broadcast service is popped up and displayed on the terminal screen, and when the user additionally receives an input for receiving the broadcast service. The broadcast service is executed (S17 and S19).

In step S15, if the type to be activated is a type other than the first type (that is, the pop-up type), is it executed by the user's selection of the broadcast service or is the broadcast service automatically executed? It is determined (S21).

In step S21, if the type of executing the broadcast service is selected by the user, it is additionally determined whether the number of broadcast services provided is more than zero (S23).

As a result of the determination, when there is no broadcast service provided, a guide line indicating that no search service is provided by the provided broadcast service is output to the terminal screen (S25).

In step S23, if there is a broadcast service provided, it is determined whether two or more are provided (S27).

In step S27, when two or more broadcast services are provided, a service list screen for allowing a user to select any one broadcast service is output to the terminal screen (S29).

Thereafter, the user selects and executes one broadcast service to be serviced through the service list screen (S31 and S33).

After receiving the broadcast service, the process is terminated through user setting for ending reception of the broadcast service (S35).

In step S13, when there is no type for activating the device 200, a process for executing a broadcast service is performed through a second type which is a general type set as a default (S37).

In addition, in step S21, when the type of broadcast service is set to be automatically executed, the corresponding application program is immediately executed to output the broadcast screen of the corresponding broadcast service to the terminal screen (S39).

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the following claims It can be understood that

In addition, the present invention is to support a variety of activation of the broadcasting service provided in the short-range area from the user's point of view, it is not only the possibility of commercialization or sales, but also the degree that can be clearly implemented in reality, industrial availability This is an invention.
