5 shows a conceptual diagram of a DLNA network.

The DLNA is a representative name of a standardization mechanism that enables sharing of contents such as music, moving pictures, and still pictures among electronic devices through a network.

The DLNA is based on the Universal Plug and Play (UPnP) protocol.

The DLNA network 200 includes a digital media server 210 (digital media server (DMS)), a digital media player 220 (digital media player, DMP), a digital media renderer 230 (digital media renderer, DMR), and It may include a digital media controller 240 (DMC).

The DLNA network may include one or more of the DMS 210, the DMP 220, the DMR 230, and the DMC 240, respectively. In this case, the DLNA may provide a standard so that each of the devices are compatible with each other. In addition, the DLNA network may provide a standard for interoperability between the DMS 210, the DMP 220, the DMR 230, and the DMC 240.

The DMS 210 may provide digital media content. That is, the DMS 210 may store and manage content. The DMS 210 may receive various commands from the DMC 240 and perform a command. For example, when the DMS 210 receives a play command, the DMS 210 may search for content to be played and provide the content to the DMR 230. The DMS 210 may include, for example, a PC, a personal video recorder (PVR), and a set top box.

The DMP 220 may control the content or the electronic device, and allow the content to be played back. That is, the DMP 220 may perform the functions of the DMR 230 for regeneration and the DMC 240 for control. The DMP 220 may include, for example, a TV, a DTV, and a home theater.

The DMR 230 may play content. The content provided from the DMS 210 may be played. The DMR 230 may include, for example, an electron frame.

The DMC 240 may provide a control function. The DMC 240 may include, for example, a mobile phone and a PDA.

In addition, the DLNA network may consist of the DMS 210, the DMR 230, and the DMC 240, or the DMP 220 and the DMR 230.

In addition, the DMS 210, the DMP 220, the DMR 230, and the DMC 240 may be terms that functionally distinguish electronic devices. For example, when the mobile phone has a control function as well as a playback function, the mobile phone may correspond to the DMP 220. When the DTV 100 manages contents, the DMP 220 may be used as well as the DMP 220. FIG. It may also correspond to).

6 shows functional components according to DLNA.

For example, a simple service discovery protocol (SSDP) may be used for device discovery. You can also use the simple object access protocol (SOAP) for control.

The media transport layer may use HTTP 1.0 / 1.1. For streaming playback. Alternatively, real-time transport protocol (RTP) can be used.

The media format layer may use images, audio, AV media, and XHTML (Extensible Hypertext Markup Language) documents.

7 is a flowchart illustrating an operation process of a mobile terminal according to an embodiment of the present invention.

As shown in these drawings, the controller (180 of FIG. 1) of the mobile terminal 100 according to an embodiment of the present invention may allow the step (S10) of executing the first content to proceed.

The first content may be one of various contents stored in a memory (160 of FIG. 1) of the mobile terminal 100. The storage may include not only a case where the mobile terminal 100 is permanently or semi-permanently stored in the memory (160 of FIG. 1) but also a case where the storage is temporarily received by a streaming method from the outside. The content may be various types such as web documents, video, audio, still images, Ani-Gifs, and the like that may be executed in the mobile terminal 100 and other devices (1000, 2000 of FIG. 11). Furthermore, the content may be sub-content included in one content. For example, in the case of a web document, a sub document such as a video and a still image may be included in the content of the web document.

The first content may be selected and executed by a user's selection or a control signal of the controller (180 of FIG. 1). The selected first content may be executed in the mobile terminal 100. That is, it means that it can be output through the output unit (150 of FIG. 1) of the mobile terminal 100. For example, when the first content is a web document, it means that the web document may be displayed through the display 151.

While the first content is being executed, a step S20 of determining whether to execute other content may be performed.

Other content may be selected by a user's selection or a control operation of the controller 180 of FIG. 1. The mobile terminal 100 according to an embodiment of the present invention may allow content currently being executed in another device (1000, 2000 of FIG. 11) to be executed if other content is selected in addition to the content currently being executed. In other words, rather than performing multi tasking in one terminal, it means that the multi tasking may be performed using other devices (1000, 2000 of FIG. 11) that exist around. By sending the content that was initially being executed to another device (1000, 2000 of FIG. 11) and allowing the selected new content to be executed, the mobile terminal 100 has more resources for executing the newly selected content. ) Can be assigned. Therefore, the user can expect the improvement of the device performance. Furthermore, the user can enjoy the content more effectively by sending the content that was originally executed to the other device (1000, 2000 of FIG. 11) optimized therein.

The other content may be sub content included in one content. For example, as described above, when the content is a web document, only the still image included in the web document may be executed on another device (1000,200 in FIG. 11).

If it is determined to execute the other content, the step S30 of transmitting the first content to another device (1000, 2000 of FIG. 11) may proceed.

Other devices 1000, 2000 of FIG. 11 may be appropriately selected. This means that an optimized device can be selected according to the characteristics of the first content to be transmitted. For example, if the first content to be transmitted is an HD video, it can be transmitted to a nearby HD-TV. If the first content to be transmitted is an MP3 music file, it can be transmitted to a nearby MP3 player. Which device to transmit may be determined by various criteria, which will be described in more detail in the corresponding section.

The transmission of the first content may include the case of streaming or fully transmitting the first content to another selected device (1000, 2000 of FIG. 11). Streaming may refer to the case of continuously transmitting data to other selected devices (1000, 2000 of FIG. 11) without actually transmitting the content itself completely. In contrast, the transmission may mean a case where the content is transmitted to another device (1000, 2000 of FIG. 11) substantially selected all at once.

In operation S40, the second content may be executed.

Since the mobile terminal 100 no longer executes the first content, the mobile terminal 100 can concentrate system resources on the execution of the second content. Therefore, the execution of the second content can proceed smoothly.

8 is a view schematically showing the operation of the mobile terminal of FIG.

As shown in the drawing, the mobile terminal 100 according to an embodiment of the present invention can transmit the content being executed to another device and execute new content.

As shown in FIG. 8A, the mobile terminal 100 may be executing A content. While executing content A, the user may execute content B and transmit A to the first device 1000 which is another device.

As shown in FIG. 8B, the controller (180 of FIG. 1) may transmit A content to the first device 1000. In this case, as described above, the A content may be transmitted to the first device 1000 in one of a streaming method and a transmission method. The A content may be transmitted to the first device 1000, and the mobile terminal 100 may execute the B content. The mobile terminal 100 and the first device 1000 may communicate according to the DLNA standard.

Some of the contents stored in the mobile terminal 100 are executed in the first device 1000, and others are executed in the mobile terminal 100, thereby multi-testing without excessive load on the resources of the mobile terminal 100. You can have a king environment built.

FIG. 9 is a signal flow diagram illustrating a signal flow between the mobile terminal of FIG. 7 and another device.

As shown, the mobile terminal 100 according to an embodiment of the present invention may execute the first content (S10).

While the first content is being executed, the second content may be selected (S20). The second content may be selected by a control operation of the user or the controller 180 of FIG. 1. When the second content is selected, the selected second content may be executed in the mobile terminal 100 and the first content may be executed in another device.

The device to transmit the first content may be selected (S24). The device to transmit the first content may be selected based on a predetermined criterion. For example, it may be selected based on the type of the first content, the communication state according to the distance to the mobile terminal 100, and the like.

When the device to transmit the first content is selected as the first device 1000, the first content may be transmitted (S30). The first device 1000 that has received the first content may execute the first content (S32).

The mobile terminal 100 transmitting or transmitting the first content to the first device 1000 may execute the selected second content (S40). At this point, the first and second contents may be simultaneously executed in the first device 1000 and the mobile terminal 100.

The third content may be selected (S52). When the third content is selected, the second content currently being executed in the mobile terminal 100 can be transmitted to another device. Therefore, the device to transmit the second content may be selected (S54).

When a device for transmitting the second content is selected, the second content may be transmitted to the selected second device 2000 (S60).

The second device 2000 having received the second content may execute the second content in operation S62, and the mobile terminal 100 may execute the third content in operation S70. At this point, the first, second, and third contents may be simultaneously executed in the first and second devices 1000 and the mobile terminal 100. That is, the content stored in the mobile terminal 100 is multi-tasked and executed in a plurality of devices.

10 to 12 illustrate the operation of the mobile terminal according to the signal flow diagram of FIG. 9.

As shown in these figures, content may be transmitted to and executed by other devices 1000 and 2000.

As illustrated in FIG. 10C, the A content may be transmitted to the first device 1000, and the B content may be executed in the mobile terminal 100.

As shown in FIG. 11, while the B content is being executed in the mobile terminal 100, the A content may be executed in the first device 1000. Furthermore, the user or the controller (180 of FIG. 1) may want to transmit the B content to the computer that is the second device 2000.

As shown in FIG. 12, the B content is transmitted to the second device 2000 to be executed, and the mobile terminal 100 may execute the C content. In this case, the mobile terminal 100 may transmit content data in a streaming manner. That is, the mobile terminal 100 may directly or indirectly control the execution of content in the first and second devices 1000 and 2000. Although it is possible to control the execution on other devices, the mobile terminal 100 executes only the C content directly. Therefore, even if three contents are executed, the mobile terminal 100 can execute C contents smoothly. Such a point means that effective resource allocation is possible considering the limited resources of the mobile terminal 100 having a mobile characteristic.

FIG. 13 is a signal flow diagram illustrating a signal flow between the mobile terminal of FIG. 7 and another device.

As shown, the mobile terminal 100 according to an embodiment of the present invention may be executing the third content (S70). In addition, the first and second devices 1000 and 2000 may be executing the first and second contents (S32 and S62).

An operation signal for the first content may be obtained (S80). The operation signal for the first content may be obtained from the user of the mobile terminal 100 or from the controller (180 of FIG. 1) of the mobile terminal 100. As described above, even when the content is transmitted to the first and second devices 1000 and 2000, the mobile terminal 100 may have a control right for executing the content. Therefore, the user can manipulate the reproduction of the first content by operating the mobile terminal 100.

The obtained operation signal may be transmitted to the first device 1000 (S82). The operation signal for the first device 1000 may be made according to the DNLA rule.

After acquiring the manipulation signal, the first device 1000 may change an execution state of the first content (S84). Meanwhile, the first device 1000 may transmit (S86) the mobile terminal 100 having the control right to the execution state of the first content at an appropriate time.

An operation signal for the second content may be obtained (S90). The mobile terminal 100 may also have a control right for the second content. Accordingly, the user may manipulate the execution state of the second content by manipulating the mobile terminal 100 without directly manipulating the second device 2000.

When the operation signal is transmitted to the second device 2000 (S92), the second device 2000 changes the execution state of the second content (S92), and transmits the execution state to the mobile terminal 100 (S96). can do.

FIG. 14 is a diagram illustrating an operation of a mobile terminal according to the signal flow diagram of FIG. 13.

As shown in the drawing, the mobile terminal 100 may be executing C content. At the same time, the A device may be executed in the first device 1000, and the B content may be executed in the second device 2000.

The mobile terminal 100 may transmit a control signal to the first device 1000 executing the A content. The first device 1000 receiving the control signal may change the execution state of the A content according to the control signal.

The mobile terminal 100 may control the second device 2000 executing the B content. The second device 2000 receiving the control signal from the mobile terminal 100 may stop or stop the execution of the B content.

For example, in the case of moving image content, it means that it may be a method of continuously providing the portion necessary to play the content to the first device 1000. By transmitting data in a streaming manner, it is possible to minimize the memory capacity required for the first device 1000.

The method of completely transmitting data may refer to a method of copying or moving content data from the mobile terminal 100 to the first device 1000. If the data is completely transmitted to the first device 1000, the load associated with the transmission of the content may not be generated in the mobile terminal 100 after the transmission. Therefore, the mobile terminal 100 can control the first device 1000 with only a minimum control signal.

FIG. 16 is a diagram illustrating a screen for managing content transmitted from another mobile terminal to another device.
