Description

PRIORITY
• This application claims priority under 35 U.S.C. §119(a) to patent application Ser. No. 10-2011-0105490, filed on Oct. 14, 2011 in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference.
BACKGROUND
• 1. Field of the Invention
• The present invention relates generally to a user terminal device and a content-sharing method thereof, and more particularly, to a user terminal device capable of searching for and sharing content locally or via a network and a content-sharing method of the user terminal device.
• 2. Description of the Related Art
• Recent developments in electronic technology have paved the way for the development and commercialization of various types of electronic devices, and, particularly, user terminal devices with improved functionality such as, for example, smartphones, smart TeleVisions (TVs) and the like.
• Users connect their user terminal devices and various peripheral devices via a network by using, for example, a Digital Living Network Alliance (DLNA) function, which allows users to share content such as music, photos, videos, and the like between multiple devices.
• A device that provides content is referred to as a Digital Media Server (DMS), and a device that renders content provided by a DMS is referred to as a Digital Media Renderer (DMR) or a Digital Media Player (DMP).
• A user terminal device equipped with the DLNA function accesses a DMS, and shares content with the DMS. In response to the execution of the DLNA function, the user terminal device loads by searching for content from all devices that are connected to it via a network. Since loading generally takes some time, a user who is relatively unfamiliar with the DLNA function mistakenly terminates the DLNA function before the DLNA function is complete. Additionally, it is generally not easy for the user to select a DMS and a DMR and properly use the DLNA function.
• Therefore, there is a need for methods for the user to efficiently use the DLNA function.
SUMMARY

DETAILED DESCRIPTION OF EMBODIMENTS OF THE PRESENT INVENTION
• Hereinafter, certain embodiments of the present invention are described in greater detail with reference to the accompanying drawings. Similar components is designated by similar reference numerals although they are illustrated in different drawings. In the following description, a detailed explanation of known related functions and parts is omitted to avoid unnecessarily obscuring the subject matter of the present invention.
• FIG. 1 is a diagram illustrating a content sharing system according to an embodiment of the present invention. Referring toFIG. 1, the content sharing system includes auser terminal device100, an Access Point (AP)200, and a plurality ofdevices10,20,30, and40. Theuser terminal device100 and each of thedevices10,20,30, and40 form a network via the AP200. Theuser terminal device100 and thedevices10,20,30, and40 are illustrated inFIG. 1 as connected to one another via the AP200. Alternatively, theuser terminal device100 and thedevices10,20,30, and40 form a network via other types of relay devices or form a network by being directly connected to one another.
• In the case in which a content sharing function is selected, theuser terminal device100 searches for one or more devices that are connected to it via a network, i.e., thedevices10,20,30, and40, via the AP200. The term ‘content sharing function’ indicates a function of sharing content between multiple devices and allowing the multiple devices to reproduce the shard content. For example, the content sharing function is a Digital Living Network Alliance (DLNA) function.
• Theuser terminal device100 operates as a Digital Multimedia Server (DMS) that provides content or as a Digital Multimedia Renderer (DMR) or a Digital Multimedia Player (DMP) that reproduces or plays content provided by other devices. A device that reproduces content will be referred to as a rendering device.
• In the case in which a content sharing function is selected, theuser terminal device100 operates in local mode or network mode.
• The term “local mode” indicates a mode for providing content present in theuser terminal device100 to a rendering device. In local mode, theuser terminal device100 serves as a DMS. In local mode, theuser terminal device100 is prevented from accessing other DMSs or loading any content information, thus saving time. The operation of theuser terminal device100 in local mode also includes searching through one or more devices that are within a limited range of the user terminal device100 (for example, one or more devices that are connected to theuser terminal device100 via a local interface).
• The term “network mode” indicates a mode in which theuser terminal device100 searches content from its network and provides the identified content to a rendering device. In network mode, theuser terminal device100 requests content information by searching thedevices10,20,30, and40, which are connected to theuser terminal device100 via a network. For example, theuser terminal device100 broadcasts a data request signal via the
• AP200. In response to receiving the data request signal via theAP200, each of thedevices10,20,30, and40 transmits a response signal including device information relating to a corresponding device. Theuser terminal device100 accesses each of thedevices10,20,30, and40 based on the device information included in the response signal transmitted by each of thedevices10,20,30, and40, and thus acquires content information. One or more DMSs, among thedevices10,20,30, and40 that are connected to theuser terminal device100 via a network, transmits content information that the DMSs can provide to theuser terminal device100. Theuser terminal device100 acquires detailed content information relating to the content based on the information transmitted by the DMSs by using the Simple Object Access Protocol (SOAP). Theuser terminal device100 displays the detailed content information and allows a user to select desired content based on the detailed content information. If the user selects content, theuser terminal device100 requests a DMS having the selected content to transmit the selected content to a rendering device. The rendering device is one ofdevices10,20,30, and40 that are connected to theuser terminal device100 via a network or theuser terminal device100. If the rendering device is one of thedevices10,20,30, and40, theuser terminal device100 operates as a Digital Multimedia Controller (DMC), and controls the operation of the rendering device. The DMS transmits the selected content to the rendering device by using the HyperText Transfer Protocol (HTTP).
• In local mode, theuser terminal device100 cannot perform a browsing function to browse through other devices or a library function to provide a library to other devices, but can perform a rendering function to provide content to a rendering device or control the operation of a rendering device.
• The user selects one of the local mode and the network mode. In response to the selection of one of the local mode and the network mode by the user, theuser terminal device100 provides a UI that corresponds to the selected mode while operating in the selected mode.
• For example, in response to the selection of an icon for performing a content sharing function, theuser terminal device100 displays a UI that corresponds to whichever of the local mode and the network mode is set as default mode for the content sharing function. If the default mode for the content sharing function is the local mode, theuser terminal device100 searches for content therein and displays the identified content in a local mode UI so that the user selects content from the local mode UI. In response to the selection of content from the local mode UI, theuser terminal device100 displays a list of devices from which a target-rendering device to share the selected content with is selected. Alternatively, theuser terminal device100 reproduces the selected content and then displays the list of devices in response to the user selecting a menu for choosing the target-rendering device while viewing the selected content. In response to the selection of the target-rendering device from the list of devices by the user, the selected content is transmitted to the target-rendering device.
• A mode-switching area for switching from one mode to another mode is provided in the local mode UI. The user switches theuser terminal device100 from local mode to network mode by using the mode-switching area in the local mode UI.
• When theuser terminal device100 is switched from local mode to network mode, theuser terminal device100 searches for content from thedevices10,20,30, and40, which are all connected to theuser terminal device100 via a network, and displays the found content in a network mode UI. In response to the selection of content in the network mode UI, theuser terminal device100 displays a list of devices from which to select the target-rendering device. In response to the selection of the target-rendering device from the list of devices, theuser terminal device100 transmits a control signal to a DMS to send the selected content to the target-rendering device.
• Alternatively, theuser terminal device100 requests the DMS having the selected content to send the selected content. In response to receiving the selected content, theuser terminal device100 reproduces the selected content. In response to the user selecting a particular menu while viewing the selected content, theuser terminal device100 displays a list of devices, and allows the user to select the target-rendering device from the list of devices. In response to the selection of the target-rendering device, theuser terminal device100 directly transmits the selected content to the target-rendering device or transmits a control signal to the DMS having the selected content so that the DMS having the selected content transmits the selected content to the target-rendering device.
• The user selects theuser terminal device100 from a list of devices displayed by theuser terminal device100 as the target-rendering device.
• A mode-switching area is also provided in the network mode UI. The user switches theuser terminal device100 from the network mode to the local mode by using the mode-switching area in the network mode UI.
• In another example, in response to the execution of a content sharing function, theuser terminal device100 displays an initial UI to select one of the local mode and the network mode. In response to the user selecting the local mode from the initial UI, theuser terminal device100 searches for content therein, and displays the identified content in a local mode UI.
• In response to the user selecting the network mode from the initial UI, theuser terminal device100 searches its network for content and displays the found content in a network mode UI.
• In this example, a mode-switching area for switching theuser terminal device100 from the local mode to the network mode or vice versa is provided in the local mode UI and the network mode UI, respectively.
• Alternatively, a menu for returning to the initial UI is provided. The user returns to the initial UI by using this menu, and then switches theuser terminal device100 from the local mode to the network mode or vice versa.
• FIG. 2 is a block diagram illustrating a user terminal device according to an embodiment of the present invention. Referring toFIG. 2, theuser terminal device100 includes anetwork interface unit110, acontrol unit120, adisplay unit130, and astorage unit140. Thenetwork interface unit110 is connected to a network. For example, thenetwork interface unit110 is connected to a mobile communication network or a Wireless Fidelity (WiFi®) network by using a mobile communication protocol or a WiFi® protocol.
• Thestorage unit140 stores content or various programs. For example, various types of multimedia content items such as videos, photos, music, and etc is stored in thestorage unit140.
• Thedisplay unit130 displays various types of UIs under the control of thecontrol unit120. In the case in which thedisplay unit130 includes a touchscreen, the user enters a variety of user commands to theuser terminal device100 simply by directly touching a UI on thedisplay unit130. Alternatively, In the case in which thedisplay unit130 does not include a touchscreen, the user enters a variety of user commands to theuser terminal device100 by using various keys provided on the main body of theuser terminal device100 or various types of input tools that are connected to theuser terminal device100 such as, for example, a mouse, a keyboard, a joystick and the like.
• Thecontrol unit120 performs various functions by controlling the operation of theuser terminal device100 in response to receiving various user commands from the user. In the case in which a content sharing function is selected, thecontrol unit120 searches for and share content while operating in the local mode or the network mode.
• In the case in which the local mode is selected, thecontrol unit120 searches for content from thestorage unit130 and controls thedisplay unit130 to display the results of the search in a local mode UI.
• In the case in which the network mode is selected, thecontrol unit120 searches for all the devices that are connected to theuser terminal device100 via a network with the aid of thenetwork interface unit110, searches for content from the corresponding devices, and controls thedisplay unit130 to display the search results in a network mode UI.
• The local mode UI and the network mode UI each includes a mode-switching area for switching theuser terminal device100 from the local mode to the network mode or vice versa. In response to the manipulation of the mode-switching area, thecontrol unit120 switches theuser terminal device100 from the local mode to the network mode or vice versa. In the case in which one of the local mode and the network mode is set as the default mode, thecontrol unit120 controls thedisplay unit130 to display a UI for whichever of the local mode and the network mode is set as default mode first. Then, in response to a mode switch between the local mode and the network mode, thecontrol unit120 controls thedisplay unit130 to display a UI for the local mode or the network mode not set as default mode.
• FIG. 3 is a diagram illustrating a local mode UI, a network mode UI, and a method of switching from the local mode to the network mode in the case in which the local mode is set as default mode, according to an embodiment of the present invention.
• Referring toFIG. 3, in response to the selection of anicon50 for performing a content sharing function when a background screen (a) is displayed on thedisplay unit130 of theuser terminal device100, thedisplay unit130 displays a local mode UI (b).
• The local mode UI (b) includes animage area60 in which an image indicating that theuser terminal device100 is in the local mode is displayed, a mode-switchingarea70, and aninformation area80 in which the number of content items in each content category that are present in thestorage unit140 is displayed.
• The mode-switchingarea70 includes a bar-shaped section and a sliding switch that is provided in the bar-shaped section. The sliding switch slides within the bar-shaped section in response to being touched or dragged by the user. For example, a first end of the bar-shaped section corresponds to the local mode, and a second end of the bar-shaped section corresponds to the network mode. In this example, theuser terminal device100 is switched to the local mode in response to the sliding switch sliding toward the first end of the bar-shaped section, and is switched to the network mode in response to the sliding switch sliding toward the second end of the bar-shaped section.
• Theinformation area80 displays various content categories. For example, referring toFIG. 3, theinformation area80 displays a “Videos” category, a “Photos” category, and a “Music” category. However, there is no restriction as to the types of content categories that is displayed in theinformation area80.
• In response to the sliding switch sliding toward the second end of the bar-shaped section, thecontrol unit120 switches theuser terminal device100 to the network mode, and a network mode UI (c) is displayed on thedisplay unit130.
• The network mode UI (c) has the same configuration as the local mode UI (b). That is, the network mode UI (c) includes animage area60, a mode-switchingarea70, and aninformation area80. In theimage area60 of the network mode UI (c), an image indicating that theuser terminal device100 is in the network mode is displayed. Theinformation area80 of the network mode UI (c) displays the total number of content items that are found from the network of theuser terminal device100, and thus provides different content quantities from theinformation area80 of the local mode UI (b). In response to theuser terminal device100 being switched to the network mode, theuser terminal device10 searches for content in real time for a predefined amount of time (for example, less than a second) from thedevices10,20,30, and40 that are connected to theuser terminal device100 via a network, and displays the number of content items in each content category that are found from thedevices10,20,30, and40. The counting of content items is performed during or after the search of content from thedevices10,20,30, and40. Theinformation area80 of the network mode UI (c) displays the total number of content items found from thedevices10,20,30, and40 after the search of content from thedevices10,20,30, and40, or displays the number of content items that are counted as they are found from thedevices10,20,30, and40 in the course of the search of content from thedevices10,20,30, and40. In the latter, the number of content items in each category is displayed in theinformation area80 of the network mode UI (c) as incrementally increasing. In themode switching area70 of the network mode UI (c), unlike in themode switching area70 of the local mode UI (b), a sliding switch is displayed at a side of themode switching area70 corresponding to the network mode.
• The user chooses one or more content categories to be displayed in theinformation area80 of the local mode UI (b) or the network mode UI (c).
• FIG. 4 is a diagram illustrating selecting content using a local mode UI, according to an embodiment of the present invention. Referring toFIG. 4, in response to a content category (for example, a “Videos” category) being selected from aninformation area80 of a local mode UI (b), the local mode UI (b) displays information on one or more content items that belong to the “Videos” category as a list or as a thumbnail view. For example, in response to the selection of the “Videos” category or a “Music” category, a list (d) including one or more content items included in the selected category is displayed. Alternatively, in response to the selection of a “Photos” category, a thumbnail view (e) displaying one or more photos included in the “Photos” category is displayed.
• The user easily identifies each photo from the thumbnail view (e) without having to see text data. The user easily identifies each video or music content from the list (d) with the aid of text data relating to the title or other identification information of each video or music content. In the example illustrated inFIG. 4, the manner in which content information is displayed varies from one content category to another content category. In another example, content information is uniformly displayed either as a list or as a thumbnail list irrespective of content category.
• In the example illustrated inFIG. 4, the list (d) also provides the representative image of each content item. In another example, no representative image is provided for each content item classified into the “Music” category.
• A plurality ofcategory tabs81,82, and83 is displayed at the top of the list (d) or at the thumbnail view (e). The user selects one of thecategory tabs81,82, and83 to view a list of content items or a thumbnail view relevant to the selected category tab. If too many content items are displayed in a list or a thumbnail view, the user is allowed to scroll up and down or left and right in the list or the thumbnail view to identify content information relating to each of the content items.
• The user selects a content item from the list (d) or the thumbnail view (e). Thecontrol unit120 reads out the selected content item from thestorage unit140, and plays the read-out content item. To play the read-out content item, one or more additional elements such as, for example, an audio processor for processing an audio signal, a speaker for outputting an audio signal, a video processor for processing a video signal, and the like, are required. However, since these additional elements are well known to one of ordinary skill in the art, detailed descriptions and illustrations of these additional elements will be omitted.
• In response to the user selecting a menu in a particular area on the screen of theuser terminal device100 or selecting a particular key on the main body of theuser terminal device100 during the play of the read-out content item, a list of one or more rendering devices from which to select a target-rendering device to share the read-out content item with is displayed. In response to the selection of one of the rendering devices, thecontrol unit120 transmits the read-out content item to the target-rendering device via thenetwork interface unit110.
• FIG. 5 is a diagram illustrating a method of selecting content using a network mode UI, according to an embodiment of the present invention. Referring toFIG. 5, the user identifies content information relating to each content item in each content category by selecting one of a plurality of content categories displayed in aninformation area80 of a network mode UI. The identified content information is displayed as a list (d) or a thumbnail view (e).
• In network mode, content is provided by various devices connected to theuser terminal device100 via a network. Thus, to allow the user to easily identify the source of each content item,device icons91 and92 are additionally provided on the list (d) or the thumbnail view (e). Various types of icons such as, for example, an icon (i.e., the device icon91) representing a mobile phone and an icon (i.e., the device icon92) representing a TV, are displayed on the list (d) or the thumbnail view (e) along with content information relating to each content item.
• In response to the selection of a content item from the list (d) or the thumbnail view (e), theuser terminal device100 is provided with the selected content item from a DMS having the selected content item, and plays the selected content item. For example, thecontrol unit120 issues a request for the selected content item to the DMS. In response to receiving the selected content item from the DMS, thecontrol unit120 controls thedisplay unit130 to play the selected content item. In response to the user selecting a menu for selecting a target-rendering device during the play of the selected content item, thecontrol unit120 controls thedisplay unit130 to display a list of one or more rendering devices from which to select the target-rendering device. In response to the selection of the target-rendering device, thecontrol unit120 transmits a control signal to the DMS to request the DMS to transmit the selected content item to the target-rendering device.
• Alternatively, thecontrol unit120 directly transmits the selected content item provided by the DMS to the target-rendering device.
• Alternatively, in response to the selection of a content item from the list (d) or the thumbnail view (e), thecontrol unit120 controls thedisplay unit130 to display a list of one or more rendering devices from which to select the target-rendering device, and controls the DMS to transmit the selected content item to the target-rendering device.
• In the above examples, theuser terminal device100 serves as a DMC in response to the provision of content to the target-rendering device. That is, thecontrol unit120 controls thedisplay unit130 to display a control UI for controlling the operation of the target-rendering device. The control UI displays various control menus that are selected or manipulated by the user. In response to the selection of one of the various control menus by the user, thecontrol unit120 performs various operations such as, for example, playing, stopping, and pausing content, and the like.
• In response to the selection of a content item from the list (d) or the thumbnail view (e), theuser terminal device100 is provided with the selected content item from theuser terminal device100 is provided with the selected content item from a DMS having the selected content item, and plays the selected content item. For example, thecontrol unit120 issues a request for the selected content item to the DMS. In response to receiving the selected content item from the DMS, thecontrol unit120 controls thedisplay unit130 to play the selected content item. In response to the user selecting a menu for selecting the target-rendering device during the play of the selected content item, thecontrol unit120 controls thedisplay unit130 to display a list of one or more rendering devices from which to select the target-rendering device. In response to the selection of the target-rendering device, thecontrol unit120 transmits a control signal to the DMS to request the DMS to transmit the selected content item to the target-rendering device.
• In local mode, theuser terminal device100 collects content information relating to each content item that is stored in thestorage unit140.
• Alternatively, in network mode, theuser terminal device100 needs to collect content and content information relating to the content from each DMS that is connected to theuser terminal device100 via a network, and displays the collected content and the collected content information in a list or a thumbnail view. The term “content information” includes a representative image, text data, a thumbnail image, and various information such as, for example, the creator of content, and the name of a DMS that provides content. Collecting of content information is referred to as gathering.
• In response to a switch from the local mode to the network mode, thecontrol unit120 generates a DMS content table, generates a network mode UI based on the DMS content table, and provides the network mode UI to thedisplay unit130. The DMS content table displays various information such as, for example, DMS information, content type information, folder names, file names, and the like. If no new content is found, theuser terminal device100 displays the network mode UI based on previously-loaded content information without the need to perform gathering. Alternatively, if new content is found, theuser terminal device100 needs to perform gathering to collect content information relating to the new content. For example, the new content is gathered from an existing DMS or from a new DMS that is newly added to the network of theuser terminal device100. Thecontrol unit120 performs gathering periodically to collect information necessary for updating.
• Since gathering generally takes time, the user often mistakenly determines that theuser terminal device100 is malfunctioning or has stopped operating even when theuser terminal device100 is still performing gathering. Moreover, since it is generally difficult for the user to precisely determine when gathering is complete, the user stops gathering even when gathering is not yet complete.
• To address these problems, thecontrol unit120 displays a Graphic User Interface (GUI) indicating the progress of gathering on the screen of theuser terminal device100 so that the user easily identifies the progress of gathering.
• FIG. 6 is a diagram illustrating an example of a GUI image that is additionally displayed on a thumbnail view. Referring toFIG. 6, thedisplay unit130 displays a thumbnail view of one or more previously loaded content items, and also displaysdevice icons310,320, and330 that respectively represent devices each having new content items. AGUI400 is displayed over a device icon corresponding to a current device on which a gathering operation is being performed, for example, thedevice icon310, to indicate the progress of the gathering operation.
• InFIG. 6, theGUI400 is implemented as a progress bar. That is, in another example, theGUI400 may be implemented as a progress circle that is gradually filled clockwise or counterclockwise as the gathering progresses. Alternatively, in another example, theGUI400 may be implemented as an image indicating a percentage that expresses the progress of gathering.
• When the gathering operation for the current device is complete, thecontrol unit120 controls thedisplay unit130 to apply a graphical effect to the device icon corresponding to the current device, i.e., thedevice icon310. For example, when the gathering operation for the current device is complete, thedisplay unit130 displays one or more content icons310-1 to310-5, representing one or more content items that is provided by the current device, along with a graphical effect of thedevice icon310 exploding and the content icons310-1 to310-5 pouring out of thedevice icon310. However, there is no restriction on the type of graphical effect that may be applied by thedisplay unit310.
• When gathering for one device is complete, thecontrol unit120 initiates gathering for another device. That is, thecontrol unit120 sequentially performs gathering for one device and gathering for another device. Therefore, when gathering for the current device is complete, thecontrol unit120 displays aGUI400 over thedevice icon320 corresponding to a subsequent device that is subject to gathering after the current device.
• FIG. 7 is a diagram illustrating a GUI that is additionally displayed on a list. Referring toFIG. 7,device icons510,520, and530 respectively representing devices each having new content items is displayed at the bottom of a list of content items, and aGUI600 is displayed next to a device icon corresponding to a current device on which gathering is being performed, i.e., thedevice icon510, to indicate the progress of the gathering operation for the current device. When the gathering operation for the current device is complete, thedevice icon510 disappears, and a content item510-1 that is provided by the current device is added to the list, and aGUI600 is displayed next to thedevice icon520 corresponding to the device that is subject to gathering after the current device.
• If, during a gathering operation for a particular device, a device icon corresponding to the particular device is touched, thecontrol unit120 stops the gathering operation. In this example, thecontrol unit120 is configured to initiate a gathering operation for another device or to perform no gathering any longer.
• According to the above-mentioned examples, the user chooses between the local mode and the network mode with convenience. A content sharing function is used to transmit content present in theuser terminal device100 to another device such as, for example, a TV or and to allow the TV to play the content. In this example, since there is no need to search for content from all the devices that are connected to theuser terminal device100 via a network, the user shares the content present in theuser terminal device100 simply by selecting a content item from theuser terminal device100 and selecting a rendering device to share the selected content item with.
