3, the smart device 100 constituting the multivision includes a short distance communication module 110, a touch sensing module 120, a video output module 130, a storage module 140, (150).

The short-range communication module 110 performs communication with other smart devices constituting the multivision. For example, a Bluetooth communication module.

The touch sensing module 120 senses a user's touch, and may include an illuminance sensor or a heat sensing sensor. More specifically, the touch sensing module 120 senses a grip state of a user performed for replacement of the corresponding smart device 120, and may be installed at the edge of the smart device 100, for example.

The image output module 130 displays and outputs the divided images provided from the control module 150.

The storage module 140 stores an application for performing an operation of providing a multivision service through the corresponding smart device and information including the corresponding smart device identification information. At this time, the application may be configured to operate as a sub-device application or a master device application according to an operation mode. That is, the application installed in the master device M is operated as a master device application and the application installed in the sub device S is operated as a sub device application.

In addition, a management table of a matrix structure is additionally stored in the storage module 140 provided in the master device M. [ This management table is generated by the master device application. As shown in FIG. 4, the management table is composed of a matrix structure corresponding to the number and layout of the smart devices constituting the multivision. In each storage area T, The smart device identification information and the divided image information corresponding to the smart device identification information are stored.

The control module 150 performs an overall control operation to the sub device S or the master device M according to the execution of the application stored in the storage module 140. [

That is, the sub-control module included in the sub-device S controls to receive and display the divided images provided from the master device M, and also receives a touch sensing signal of the user from the touch sensor 120 , And provides the identification information and the touch sensing signal to the master device (M) through the short distance communication module (110).

In addition, the master control module included in the master device M performs reception processing on an image provided from the outside, generates a management table having the same matrix structure as the shape of the multi-vision as shown in Fig. 4, And stores the received image in the corresponding storage area T of the management table by dividing the received image so as to correspond to the number and layout of the smart devices constituting the multivision.

In addition, the master control module sends the divided image to the sub-device S disposed at the corresponding position of the multivision, and displays and outputs the divided image corresponding to the position of the sub-device S.

In addition, when the touch sensing state information is supplied from the sub-device S, the master control module predicts that a change will occur in the smart device at the corresponding position, and sets the smart device to a replacement standby state. The smart device is registered and stored in the smart device storage location, thereby performing a content reconstruction process for providing a divided image of the corresponding location to the newly registered smart device.

At this time, when the touch sensing state information is applied from two or more sub-devices (S), the master control module sets a replacement waiting order for each smart device to correspond to the reception order, and then, And reset the corresponding smart device information so as to correspond to the waiting sequence.

In addition, in the master control module, when the touch sensing status information is applied from the two sub-devices S and a replacement waiting order is set for the corresponding smart device, a registration request for smart device information When the information is received, the storage locations of the identification information for the two smart devices set in the replacement standby state in the management table are exchanged.

At this time, the external image is configured to be provided to all the smart devices 100, and the smart device 100 set as the master device M may be configured to perform the dividing process and the management process for the external image.

Next, a content reconfiguration method in a multi-vision system using a smart device will be described.

FIG. 5 is a flowchart illustrating a content reconstruction method in a multivision system using a smart device according to the present invention. FIG. 6 is a flowchart illustrating a method of providing a service using a content reconstruction method in a multivision system using a smart device according to the present invention. Fig.

First, a plurality of smart devices 100 constituting a multivision are arranged in a matrix form. At this time, the smart device 100 is provided with an application for providing a multi-vision service.

In this state, the user sets any one of the plurality of smart devices 100 as the master device M (ST10). At this time, the remaining smart devices other than the master device M are set as the sub device S '. The initial setting of the master device M may be arbitrarily set by a user or may be automatically set to a predetermined position such as a smart device 100 disposed at a central portion of the multivision according to the arrangement of the smart device 100 constituting the multivision . The master device M transmits the "master registration" information in a multicasting manner and transmits its mode to the sub device (S) based on the reception of the "master registration" information in the other smart device, S). That is, the master device M and the sub device S execute the application so as to correspond to the operation mode set for itself.

Then, the master device M creates a management table of a matrix structure corresponding to the multivision arrangement shape based on the smart device identification information forming the multivision (ST20). That is, the user provides the layout configuration information of the multivision to the master device M. For example, the user provides the number of horizontal arrangement and the number of vertical arrangement of the smart device 100 forming the multivision with the master device M to form a management table of the matrix structure. At this time, the user can provide the smart device identification information forming the multivision to the master device M together with the location information. For example, when a user assigns an area code to each position of a multivision arrangement shape and arranges a plurality of smart devices to form a multivision, the multivision area code corresponding to the corresponding location is provided to the corresponding smart device, The smart device 100 may provide its own area code and identification information to the master device M so that the master device M can generate a management table having a structure as shown in FIG.

When the master device M receives a video signal from the outside (ST30), the master device M divides the received video into a matrix corresponding to the multi-vision arrangement shape (ST40). For example, when the management table is a matrix structure of "3 × 3" type, the master device M generates 9 divided images of 3 × 3 type.

The master device M transmits the divided images generated in step ST40 to the smart devices stored in the storage area T corresponding to the corresponding multivision area in the management table (ST50). That is, the master device M stores the divided images in the storage area T of the management table corresponding to the corresponding multi-vision position, and stores the divided images in the storage area T, And provides the divided images stored in the storage area T to the corresponding smart device. For example, the divided images stored in the first area of the management table shown in FIG. 4 are provided to the smart device stored in the first area.

Then, each of the smart devices 100 forming the multivision displays and outputs the divided images provided to the smart device 100 (ST60). At this time, the master device M sends the divided images to all the sub-devices S, and then provides the agreed "video output start" information to all the sub-devices S in a multicasting manner, ) Can display and output the divided images corresponding to one image at a time.

If the user wants to replace the smart device due to a failure of the smart device at a certain position in the above state and the user grips the arbitrary smart device forming the multivision, And transmits the touch sensing state information to the master device M. [ At this time, the touch sensing status information includes the smart device identification information.

The master device M receives the touch sensing status information from the arbitrary smart device 100, more specifically, the sub device S (ST70), and determines the position of the sub device S that transmitted the touch sensing status information And sets a replacement standby state for the sub-device S (ST80). That is, the master device M sets the replacement standby smart device by searching the management table for the corresponding smart device identification information included in the touch sensing status information.

Thereafter, when the user places the smart device 100 at a position corresponding to a vacant position of the multivision or a storage area in which the replacement standby state is set, the corresponding smart device 100 transmits its identification information to the master device M And transmits the registration request information including the registration request information.

When the registration request information is received from the arbitrary smart device 100 (ST90), the master device M updates the smart device, that is, the sub-device information requesting registration, to the storage location of the sub- (ST100). At this time, when the touch state sensing information is received from the plurality of sub devices S, the master device M stores the touch state sensing information reception order, and then, for the smart device newly requesting registration, The arrangement position is changed and set so as to correspond to the reception order of " In this case, when replacing at least two smart devices, the user should assume a relocation operation of the smart device corresponding to the removal order of the smart devices to be replaced.

Then, the master device M provides a divided image corresponding to the corresponding position in each sub-device S based on the management table reconstructed in step ST100 (ST110).

Meanwhile, in the present invention, there may be a case where the position between the sub-apparatuses S forming the multivision is changed as necessary. In consideration of this, the master apparatus M may be provided with two sub- When the touch state detection information is received from the smart device identification information and the registration request information including the same smart device identification information as the replacement smart device identification information is received, It is also possible to perform mutual replacement storage.

FIG. 6 illustrates a service in a case where the position of the sub-device S3 in the third position and the sub-device S4 in the fourth position in the multi-vision are exchanged.

(1) First, when the user grips the sub-device S4 at the fourth position and separates the sub-device S4 from the multi-vision, the sub-device S4 at the fourth position transmits the touch sensing status information to the master device M. At this time, the master device M sets a replacement standby state for the sub-device S4 at the fourth position. In the multi-vision environment, the fourth position is empty.

(2) If the user then disconnects the sub-device S3 at the third position from the multi-vision, the sub-device S3 at the third position sends the touch-sensitive status information to the master device M. [ At this time, the master device M also sets the replacement standby state for the sub-device S3 at the third position.

If the user places the sub-device S3 at the third position in the fourth position in the above-described state, the sub-device S3 at the third position previously transmits the registration request information to the master device M. [ At this time, the third position becomes empty in the multi-vision environment.

When the user places the sub-device S4 at the fourth position at the third position, the sub-device S4 at the previous fourth position sends the registration request information to the master device M. [

(3) If the master device M confirms the registration request information in order and transmits the touch state detection information, if the identification information is the same as that of the smart device in the replacement standby state, the master device M stores Store the locations interchangeably.

Accordingly, the master device M provides the divided contents corresponding to the fourth position to the previous third position smart device S3 newly arranged at the fourth position, So that the divided contents corresponding to the fourth position are displayed and output.

(4) Further, the master device M provides the divided contents corresponding to the third position to the previous fourth position smart device S4 newly arranged at the third position, The divided contents corresponding to the third position are displayed and output through the step S4.

In the above embodiment, only the reset process for the sub-device S among the smart devices forming the multivision has been described. However, the master device may be replaced. That is, when the user touches the master device M and tries to replace the master device M, the master device M provides the master information to the peripheral device S, The device M can be changed and set. Here, the master device information includes a management table. At this time, the image signal provided from the outside is configured to be provided to all the smart devices 100, and the division process and the management process for the corresponding image are performed only in the smart device 100 operated by the master device M It would be desirable to assume the premise.
