For example, when a smartphone and a TV share music, a music video is displayed through a TV, and a music video is output through a smart phone, thereby performing multichannel music video sharing.

The present invention can control diverse devices so that each device can perform different unique functions when content is shared. The function control may be directly controlled by the device requesting the content or automatically controlled according to the type of the opponent device in the device receiving the content request. In order to control the functions, each device can perform short-range communication and wireless communication.

In the present invention, a device requesting content sharing may operate as a master device, and a device that requests content sharing may operate as a slave device.

For example, if smartphones, pads, and TVs share a picture together, the TV acts as a viewer, and a smartphone or pad can act as a control device to control the display of pictures and edit pictures. As another example, when playing a game using a smart phone or a TV, the TV can display a game screen and the smart phone can act as a joystick for manipulating the game.

As another example, the present invention can create new content through various content sharing. In this case, two or more devices sharing the contents are devices capable of bidirectional input and control, and are performed between devices having the same inherent functions.

For example, when images or text data are shared between two smartphones, each user can memorize images or text to create new content, i.e., images or text data containing memos. In another example, when sharing music between two smartphones, a new music chorus content may be created using the calling function.

In yet another embodiment, the present invention provides a communication function for real-time content sharing so that meaningful data can be continuously stored and reused.

For example, when sharing photos, videos, and web pages, chat and comments are provided to enable communication between shareholders and to create shared histories.

Accordingly, the present invention can provide a more convenient and rich experience for users by playing the role of each device in content sharing.

3 shows a device applied to content sharing.

3, the content device may be implemented between a mobile terminal (eg, a smart phone) 100, an image display device (eg, TV) 200, a notebook 300 and pads 400 . The device has a data transmission / reception function and a display unit capable of displaying contents. The devices can perform wireless communication as well as wireless communication with each other, and each device stores ID and history information of a device sharing content. When a user wishes to share content with a new device, he or she can directly enter new device information in the shared device list or automatically register device information using proximity device detection. For convenience of explanation, the configuration of the mobile terminal will be described with reference to FIG.

4 is a flowchart illustrating a content sharing method according to an embodiment of the present invention.

As shown in FIG. 4, the user selects contents to be shared on the display unit 151 of the device 1 (S100). The content to be shared may be content viewed by the user or content in the form of a list. When the content is selected, the user selects a desired device 2 from a plurality of devices (S110). The plurality of shared devices include homogeneous and heterogeneous devices. The plurality of shared devices may be provided in the form of a device name or a name of a portable user.

After the device 2 is selected and the sharing button is pressed, the control unit of the device 1 transmits the shared content information to the device 2 through the wireless communication unit (S120). The control unit of the device 2 displays a message asking whether to perform the content sharing, and performs content sharing according to the response of the user. The shared content information may include a device ID, a shared content, or an identifier (e.g., a URL) of the shared content.

The control unit of the device 2 determines the shared device type using the device ID requesting the content sharing, and performs the sharing function stored in the memory 170 corresponding to the determined shared device type (S130). For example, if Device 1 is a smart phone and Device 2 is a TV, the control unit of the TV displays the shared content on the screen (viewer function).

When the content sharing is started, the control unit of the devices 1 and 2 provides a communication function such as a chat window according to the currently shared content type (S140). For example, when sharing pictures, videos, web pages, etc., chat and comment functions are provided to enable communication among the sharers.

In addition, the control unit of the devices 1 and 2 stores new contents or data generated by content sharing, and can continuously store and reuse the shared history (S150).
