In addition, it is equipped with the technology of IEEE 802.11 to compensate for the shortcomings of Ethernet, and it is located at the end of the Ethernet network to minimize unnecessary wiring work and maintenance costs.

In the following Embodiment 1, content playback based on location recognition of a terminal will be described.

The electronic tag 22 is provided in one or two or more terminals 10, respectively, and the tag reader 24 is installed in one or two or more spaces, respectively. The tag information of the electronic tag 22 led by the tag reader 24 is collected by the reader management server 26, and the reader management server 26, which is in wireless communication with the service server 30, is tagged with the service server 30. Send the information. And the service server 30 is built a system for controlling the terminal 10 to play the content corresponding to the received tag information. The electronic tag 22 used in the first embodiment may be an RFID tag that modulates a phase or an amplitude when an RF signal is input to return data stored in the tag to a reader. In addition, the tag reader 24 may be an RFID reader capable of transmitting and receiving information of the RFID tag. In addition, it is a matter of course that a sensor that performs a sensing role within a certain range and a device that transmits and receives a sensor to read information of the sensor may be applied.

The electronic tag 22 stores tag information for identifying the terminal 10 and transmits tag information to the outside. The sent tag information is read by the tag reader 24, and the reader management server which collects the tag reader information transmits the tag information to the service server 30. In this case, each terminal 10 in the service server 30 is identified by tag information stored in the electronic tag 22.

The terminal 10 may be composed of the middleware 14 and the content player 18 to play the content service received from the service server 30 while being in wireless communication with the service server 30. The terminal 10 recognizes the current position through a location recognition sensor such as RFID, and automatically plays back the contents such as a set video, flash, PPT, and the like.

The middleware 14 is a module that performs wireless communication with the service server 30 through a network, receives a service of the service server 30, and transmits information of the terminal 10. The middleware 14 in the embodiment includes the RFID middleware 14, and functions to collect, control, and manage identification code data continuously occurring in the RFID reader, and is hierarchically organized and distributed in connection with all components. A middleware 14 network having a structured structure is configured to communicate with each other.

The content player 18 plays the content corresponding to the content service of the server manager 36 of the service server 30 received through the middleware 14.

4A is a circuit flow diagram illustrating terminal location information and location change of a terminal according to terminal location information, and FIG. 4B illustrates a content reproduction state diagram of a terminal according to terminal location information and time information change. Referring to FIG. 4A, when the terminal plays content corresponding to an existing location and the position of the terminal changes, tag information of the electronic tag 22 is read by the tag reader 24 and the tag information is read. It is communicated to the terminal location recognition and analysis module 32 via the management server 26.

That is, if the terminal is outside the range that the tag reader 24 can detect, the terminal location recognition and analysis module 32 transmits the terminal location information to the server manager 36 indicating that the terminal cannot be recognized. The terminal provides a content service to play basic content. Next, when the terminal is located within the detection range of the tag reader 24 and is detected by the existing tag reader, the terminal location recognition and analysis module 32 transmits corresponding terminal location information to the server manager 36. Thus, the server manager provides a content service for the terminal to play the content corresponding to the existing location. Finally, when the terminal enters the detection range of the other tag reader, the terminal location recognition and analysis module 32 delivers the corresponding terminal location information to the server manager to provide the corresponding content service to the terminal so that the terminal is changed to the changed location. The corresponding content is played.

The configuration and operation of the middleware 14 and the content player 18 are the same as described above.

Proximity sensors 20a and 20b detect other terminals linked at the left and right sides of the terminal 10, and when the other sensors are detected by the proximity sensors 20a and 20b, the linked terminals are linked by the terminal recognition module 12. The recognition information is transmitted to the service server 30 and analyzed by the linked terminal analysis module 34. When N terminals 10 are connected to the currently playing terminal 10 through proximity sensors 20a and 20b such as IR and BLUETOOTH, the linked terminal may be automatically recognized to play contents composed of N split screens. At this time, the content service originally expands one piece of content and divides the content into parts, and divides the N-divided content into N terminals or has one first content and N second contents, respectively, and each of N pieces of content. When the two contents are combined, the first content is completed, and when N terminals are linked, various methods such as playing the second content may be applied.

FIG. 3A illustrates a circuit flow according to linked terminal information, and FIG. 3B illustrates a state in which the linked terminal divides and plays the content, and the individual terminal 10b reproduces the content. When the ten terminals 10a, 10b, 10c, and 10d are linked, the server manager 36 of the service server 30 causes the contents to be divided into four divided screens, and thus linked four terminals 10a, 10b, 10c, and 10d. Provides a content service capable of playing one piece of content to the four terminals 10a, 10b, 10c, and 10d. That is, when the proximity sensor detects another terminal, the linked terminal recognition module 12 reads whether the link is between the terminals. If the proximity sensor does not link between the terminals, individual terminal contents are played. However, if the link of the terminal is recognized, the linked terminal identification information is transmitted to the linked terminal analysis module 14. The linked terminal analysis module 14 detects the quantity and order of the linked terminals and transmits the linked terminal information to the server manager 36. The server manager 36 analyzes the linked terminal information to operate whether there is a content service corresponding to the linked terminal setting details. If there is a content server corresponding to the setting details, the content service is transmitted to the terminal to play the content corresponding to the content service. If not, the terminal plays the individual content.

The service server 30 includes a server manager 36 and a terminal manager 38 as described above, and further includes a terminal location recognition and analysis module 32 and a linked terminal analysis module 34.

The tag reader 24 installed in the space periodically reads the terminal 10 identification electronic tag 22 within the tag recognition range. The terminal location recognition and analysis module 32 compares the previously recognized tag information with the currently recognized tag information. If there is no change in the information, the terminal location recognition and analysis module 32 does nothing. However, if there is a change, the newly recognized tag information is transmitted to the server manager 36.

At this time, the server manager 36 modifies the terminal position information of the database unit of the content to be reproduced, and transmits the content service to the terminal 10 to display the content corresponding to the case where one terminal 10 exists in the space. In this case, the terminal 10 entering the space activates the content corresponding to the received content service.

The flow in the case where one terminal 10 further enters the space will be described below.

The tag reader 24 periodically reads the electronic tag 22 within the tag recognition range. The terminal location recognition and analysis module 32 compares the previously recognized tag information with the currently recognized tag information to check whether there is a change. If there is no change, the terminal location recognition and analysis module 32 does nothing. However, if there is a change, the recognized tag information is transmitted to the server manager 36. At this time, the server manager 36 modifies the terminal position information of the database unit corresponding to the content to be played. The server manager 36 transmits a content service corresponding to the case where one terminal 10 exists in the entered space to the additionally entered terminal 10, and the additionally entered terminal 10 transmits to the content service. Play the corresponding content.

Each terminal 10 periodically transmits unique information of each terminal 10 through proximity sensors 20a and 20b provided at left and right sides, and performs a reception standby state. When other terminals are located in close proximity and are interlinked, the proximity sensors 20a and 20b sense unique information of the other terminals. At this time, the linked terminal recognition module 12 transmits the detected unique information of the terminal 10 to the linked terminal analysis module 34 of the service server 30, the linked terminal analysis module 34 is linked The linked terminal analysis information analyzing the quantity and order of the terminals is transmitted to the server manager 36.

In addition, the linked terminal recognition module 12 recognizes the first terminal 10a on the left side and the third terminal 10c on the right side, and in the linked terminal recognition module 12 of the first terminal 10a, The second terminal 10b is recognized, and the linked terminal recognition module 12 of the third terminal 10c recognizes the second terminal 10b on the left side. The linked terminal identification information is received by the linked terminal analysis module 34 of the service server 30 and analyzed as the number of linked terminals. In the linked terminal analysis module 34, the second terminal 10b is disposed at the center, the first terminal 10a is disposed at the left side, and the third terminal 10c is disposed at the right side. Therefore, the three terminals 10a, 10b, and 10c located in the first space play the linked content which is interoperable with each other.
