At this time, the content list can display and display the content list according to the type of the content and the type of the device including the content.

FIG. 9 is a diagram illustrating another embodiment of displaying tag information in a device sharing contents according to the present invention. It can be seen that a list is generated by distinguishing a content list according to a device including a content. The tag information of the content included in the first device 910 is connected and the tag information of the content included in the second device 920 is connected. Among the illustrated tag information, there is tag information 930 included in both the first device 910 and the second device 920.

Also, by generating and displaying different sizes of the graphic data for the first device 910 and the second device 920, it can be seen that the first device 910 has a high weight. For example, the first device 910 may be in a good communication state or may have a large number of content holders, depending on the object to which the weight is set.

In addition, as shown in FIG. 9, there is an advantage in that, when devices are on the same network, shared tag information is visualized based on a device basis, thereby preventing the phenomenon of concentrating on a specific device when a content is transmitted.

FIG. 10 shows another embodiment of displaying tag information in a device sharing contents according to the present invention. It can be seen that tag information is displayed separately for each content type. That is, the music content 1000, the movie content 1010, and the photo content 1020 are distinguished, and the tag information included in the category is displayed. Accordingly, there is an advantage that the user can find desired tag information and contents more quickly.

The user can select desired tag information and contents using the pointer 1301 corresponding to the remote controller 1300. [ This will be described with reference to Figs. 12 to 13. Fig.

Further, when the user selects specific tag information, the user can view the contents list including the specific tag information, and can select and receive specific contents from the contents list. However, there is a disadvantage in that it is difficult to confirm whether the content desired by the user is correct only by the information displayed in the content list received through the tag information. Accordingly, it is possible to provide a user interface having an additional menu for confirming contents such as preview, preview, and the like of the contents before requesting transmission of the specific contents.

FIG. 11 is a diagram illustrating an example of displaying content using tag information in a device sharing content according to an embodiment of the present invention. Referring to FIG. 11, a user inputs 'Boa' through a pointer 1301 corresponding to a remote control 1300, Quot ;, a preview menu 1100 of the music content, which is a content including the tag information, is displayed. Therefore, the user has the advantage of being able to judge whether the user is listening to a part of the album jacket or music and whether the content is the content desired by the user. Accordingly, the contents viewing menu, the tag information re-searching menu, and the like other than the transmission request menu for the contents are provided, thereby enhancing user convenience.

If the content intended by the user is correct, the controller 250 may control the network interface 215 to receive the content including the selected tag information according to the tag selection signal.

As such, the controller 250 may request another device to receive the content. However, it is also possible to transmit the tag information about the stored content to another device, and transmit the content to another device according to the tag information, and the same can be applied as described in the control section for the mobile device.

Meanwhile, before the controller 250 transmits a content request signal for requesting tag information to another device, the user interface 240 receives a search word for receiving the shared tag information from the user, You can choose.

As described above, when the tag information can be received by limiting the search word or the type of the content before receiving the tag information, there is an advantage that the accuracy of the received tag information can be enhanced. In addition, there is an advantage that the contents can be transmitted and executed immediately without needing to check the contents of the contents accordingly, which is quick.

Of course, various types of contents can be linked to the same tag information before the tag information is received, thereby increasing the selection possibility of the user. However, in this case, it is inefficient to receive all of the contents including the tag information. Therefore, the controller 250 receives the metadata of the contents including the selected tag information, and transmits the metadata including the selected tag to the contents To generate a list for the user.

Accordingly, the user can select a specific content using the metadata of the content. When receiving a request signal for a specific content through the user interface 240, the user can control to receive the content, thereby reducing the network load.

By providing the remote controller 1300 in this manner, the user can easily select the tag information received from the peripheral device, and can conveniently transmit the request signal for the content corresponding to the tag information.

FIG. 14 is a diagram illustrating a data transfer protocol between devices sharing content according to an embodiment of the present invention. Referring to FIG. 14, an embodiment of a data transfer protocol between devices sharing content is described. 14, it is assumed that the first device transmits a content request signal to the second device and the third device.

The first device searches for a communicable device (S1300). And transmits a content request signal to the searched device (second device, third device). Since the content request signal has been described above, a detailed description will be omitted.

The second device and the third device transmit tag information shared with the first device (S1310, S1320). The first device receiving the shared tag information generates and displays graphic data corresponding to the tag information (S1330). At this time, weights may be given based on the number of devices including the tag information, the recommended number of times, etc., and the size, color, and the like of the graphic data may be different according to the weights.

When the user interface receives the tag selection signal from the user (S1340), the content is requested to the device including the selected tag information (S1350). In Fig. 14, it is assumed that the second device has content.

However, in order to directly connect the tag selection signal to the device having the corresponding content, it is assumed that the tag information and the content match one-to-one. If one-to-one matching does not occur, if the tag information is selected, the contents list including tag information can be displayed to select the contents.

The second device transmits the requested content to the first device (S1360). However, if the user of the second device attempts to turn off the power before the transmission is completed, the power off signal is received from the user interface of the second device (S1370). Then, after notifying the first device of power off (S1380), the transmission is stopped (S1400), and the second device is turned off (S1390).

If the controller of the first device receives a power off signal from the second device, the controller of the first device requests a power hold so that the power of the second device is turned off after the content transmission is completed Signal to the second device.

However, if the power of the second device is turned off before the transmission is completed, the first device requests the content including the selected tag information to another device (S1410). In Fig. 14, it is assumed that a request is made to the third device.

If the content requested by the third device is transmitted (S1420), the first device determines whether it is the same content as the content received previously (S1430). Whether or not the same content is available can be determined through the metadata of the content. If it is determined that the same content is the only content, the received content is continuously received (S1450). If the same content is not found, the content is requested to another device.

At this time, if the power of the second device is on, it can be retransmitted from the second device, so it can be checked whether the power is on (S1440). If there is no other device having the same content even though the power is not on, the controller of the first device can wait to take over the content when the power of the second device is turned on.

Up to now, a device sharing content using tag information has been described. As described above, embodiments in which contents are shared using tag information will be described in more detail.

As a first embodiment, media contents can be shared with each other. The tag information includes content recommendation information, a viewing count, a viewing time, a display expansion history, a sharing status, an illegal download history, . Accordingly, it is possible to receive the list of favorites of the user A by using the tag information of the media content, or to select and download the specific music content stored in the favorites. In this manner, the media itself can also be made into contents by using the tag information, and the contents can be shared by sharing the usage pattern information.

As a second embodiment, the photo content can be shared. As the tag information of the photographic contents, it is possible to store photographic contents including the person in the photograph, the location of the photographed photograph, the print, the web link information, the camera mode information, and the like, . It is possible to collect only the photo contents of the photo contents in the peripheral device that have not been printed and to print the image contents of the other users by adding tag information of the photo of the other user as tag information.

The movie contents can be shared as the third embodiment. The genre, the favorite genre, the leading actor, the director, the number of plays, the recommendation, and the comment are stored as the tag information, and only the movie contents corresponding to the favorite genre can be received. It is also possible to receive only recommended movie contents. When it is desired to view the movie content that matches the screen resolution of the other device, the resolution may be included in the tag information to receive only the movie content of the resolution appropriate.

Fig. 15 is a flowchart of a method of controlling a device sharing content according to an embodiment of the present invention. Referring to Fig. 15, an embodiment of a method of controlling a device sharing content is described. However, the same elements as those described in the device sharing the contents are not described in detail.

First, a communication-enabled device is searched (S1500). It is preferable to use a short-range communication such as Bluetooth, Zigbee, or wi-fi. However, the present invention is not limited to short-range wireless communication.

The shared tag information is received from the searched device (S1510). The tag information may include at least one of metadata of the content, keyword information of the content, usage pattern information of the content, and recommendation information of the content, and may be set differently according to the type of the content.

Based on the received tag information, graphic data for displaying a weight is generated (S1520). A weight can be given according to a predetermined reference including at least one of the number of devices sharing the tag information, the signal strength with the device sharing the tag information, and the type of the content including the tag information. Also, graphic data can be generated by varying at least one of the size, color, thickness, and movement speed of the graphic data corresponding to the tag information according to the weighted value.

The generated graphic data is displayed (S1530), and a tag selection signal is received from the user through the user interface (S1540). The metadata of the content is received from the device including the selected tag (S1550), and the list of the contents including the selected tag is displayed using the received metadata (S1560).

The list of contents can be displayed by being classified according to the type of the content or the type of device including the content, and it is possible to use the metadata of the content.

Further, the list of contents can be generated by assigning priorities according to preset criteria. The predetermined criteria may include at least one of a search ranking, a recommendation ranking, a reproduction count, and a content type for the content including the selected tag, and is available using the tag information.

In this manner, when a list of contents is ranked and displayed or divided according to the content type or the device, the user can quickly find a specific content desired by the user.

Upon receiving a request signal for a specific content included in the list from the user interface (S1570), the device is controlled according to the request signal. The request signal may be at least one of a preview signal for a specific content, a preview signal, a file copy signal, a file transmission signal, a print request signal, a reproduction request signal, and a rediscovery signal.

A file transfer signal, a print request signal, and a reproduction request signal may be transmitted to a device that stores a specific content, Lt; / RTI >

In addition, the re-search signal means that the content included in the list is not the content desired by the user. Therefore, if the request signal is a re-search signal, the range of the content including the selected tag can be set separately, and the metadata of the content including the selected tag can be re-received within the set range.

Alternatively, the re-search signal means that the content included in the list is not the content desired by the user, so that the content including the selected tag may be searched from the web. Browsing the content provided on the Web on the device is a known technique and thus a detailed description thereof will be omitted.

FIG. 16 is a flowchart of a method of controlling a device sharing content according to another embodiment of the present invention. Referring to FIG. 16, another embodiment of a method of controlling a device sharing content is described. The same points as those described above in FIG. 15 will not be described in detail.

First, a communication-enabled device is searched (S1600) and shared tag information is received from the searched device (S1610). Generates graphic data corresponding to the received tag information (S1620), and receives a tag selection signal for selecting specific graphic data using graphic data (S1630). And receives a content including tag information selected according to the tag selection signal from the external device (S1640).

In the control method of the device sharing the contents described in Fig. 15, if the contents are shared by receiving the contents metadata list using the selected tag information and receiving the contents selected in the list, And the content is directly shared.

However, if the power of the external device is turned off before completing the content reception (S1650), another device storing the tag information about the content is searched (S1660). If another device has the same content, the content is transferred (S1670), and the content transfer can be completed (S1680).

However, if it is difficult to search another device, it may wait until the power of the external device that is transmitting the content is turned on, and then receive the content when the power is turned on.

Furthermore, although the drawings are shown for convenience of explanation, it is also possible to design a new embodiment to be implemented by merging the embodiments described in each drawing. It is also within the scope of the present invention to design a computer-readable recording medium in which a program for executing the previously described embodiments is recorded according to the needs of those skilled in the art.
