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.
Accordingly, the present invention has been made to solve the above-stated problems occurring in the prior art, and an aspect of the present invention provides a user terminal device capable of effectively sharing content and a content-sharing method of the user terminal device.
According to an aspect of an embodiment, a user terminal device is provided. The user terminal device includes a network interface unit for connecting to a network; a storage unit for storing content; a control unit for operating in local mode to search for content from the storage unit or network mode to search for content from the network in response to a user's selection; and a display unit for displaying the local mode User Interface (UI) or the network mode UI in accordance with whether the control unit is operating in the local mode or the network mode, respectively.
According to another aspect of an embodiment, a content-sharing method of a user terminal device is provided. The content-sharing method includes displaying one of a local mode UI and a network mode UI, each UI including a mode switching area to switch from one mode to another mode; and displaying an other UI not yet displayed, in response to the switch from the one mode to the another mode, wherein the local mode UI is a UI corresponding to a local mode for searching for content from the user terminal device and providing the content to a rendering device and the network mode UI is a UI corresponding to a network mode for searching for content from a network to which the user terminal device is connected and providing the content to the rendering device.
The above and other aspects, features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which:
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.
In the case in which a content sharing function is selected, the user terminal device 100 searches for one or more devices that are connected to it via a network, i.e., the devices 10, 20, 30, and 40, via the AP 200. 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.
The user terminal device 100 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, the user terminal device 100 operates in local mode or network mode.
The term “local mode” indicates a mode for providing content present in the user terminal device 100 to a rendering device. In local mode, the user terminal device 100 serves as a DMS. In local mode, the user terminal device 100 is prevented from accessing other DMSs or loading any content information, thus saving time. The operation of the user terminal device 100 in local mode also includes searching through one or more devices that are within a limited range of the user terminal device 100 (for example, one or more devices that are connected to the user terminal device 100 via a local interface).
The term “network mode” indicates a mode in which the user terminal device 100 searches content from its network and provides the identified content to a rendering device. In network mode, the user terminal device 100 requests content information by searching the devices 10, 20, 30, and 40, which are connected to the user terminal device 100 via a network. For example, the user terminal device 100 broadcasts a data request signal via the
AP 200. In response to receiving the data request signal via the AP 200, each of the devices 10, 20, 30, and 40 transmits a response signal including device information relating to a corresponding device. The user terminal device 100 accesses each of the devices 10, 20, 30, and 40 based on the device information included in the response signal transmitted by each of the devices 10, 20, 30, and 40, and thus acquires content information. One or more DMSs, among the devices 10, 20, 30, and 40 that are connected to the user terminal device 100 via a network, transmits content information that the DMSs can provide to the user terminal device 100. The user terminal device 100 acquires detailed content information relating to the content based on the information transmitted by the DMSs by using the Simple Object Access Protocol (SOAP). The user terminal device 100 displays the detailed content information and allows a user to select desired content based on the detailed content information. If the user selects content, the user terminal device 100 requests a DMS having the selected content to transmit the selected content to a rendering device. The rendering device is one of devices 10, 20, 30, and 40 that are connected to the user terminal device 100 via a network or the user terminal device 100. If the rendering device is one of the devices 10, 20, 30, and 40, the user terminal device 100 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, the user terminal device 100 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, the user terminal device 100 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, the user terminal device 100 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, the user terminal device 100 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, the user terminal device 100 displays a list of devices from which a target-rendering device to share the selected content with is selected. Alternatively, the user terminal device 100 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 the user terminal device 100 from local mode to network mode by using the mode-switching area in the local mode UI.
When the user terminal device 100 is switched from local mode to network mode, the user terminal device 100 searches for content from the devices 10, 20, 30, and 40, which are all connected to the user terminal device 100 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, the user terminal device 100 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, the user terminal device 100 transmits a control signal to a DMS to send the selected content to the target-rendering device.
Alternatively, the user terminal device 100 requests the DMS having the selected content to send the selected content. In response to receiving the selected content, the user terminal device 100 reproduces the selected content. In response to the user selecting a particular menu while viewing the selected content, the user terminal device 100 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, the user terminal device 100 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 the user terminal device 100 from a list of devices displayed by the user terminal device 100 as the target-rendering device.
A mode-switching area is also provided in the network mode UI. The user switches the user terminal device 100 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, the user terminal device 100 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, the user terminal device 100 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, the user terminal device 100 searches its network for content and displays the found content in a network mode UI.
In this example, a mode-switching area for switching the user terminal device 100 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 the user terminal device 100 from the local mode to the network mode or vice versa.
The storage unit 140 stores content or various programs. For example, various types of multimedia content items such as videos, photos, music, and etc is stored in the storage unit 140.
The display unit 130 displays various types of UIs under the control of the control unit 120. In the case in which the display unit 130 includes a touchscreen, the user enters a variety of user commands to the user terminal device 100 simply by directly touching a UI on the display unit 130. Alternatively, In the case in which the display unit 130 does not include a touchscreen, the user enters a variety of user commands to the user terminal device 100 by using various keys provided on the main body of the user terminal device 100 or various types of input tools that are connected to the user terminal device 100 such as, for example, a mouse, a keyboard, a joystick and the like.
The control unit 120 performs various functions by controlling the operation of the user terminal device 100 in response to receiving various user commands from the user. In the case in which a content sharing function is selected, the control unit 120 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, the control unit 120 searches for content from the storage unit 130 and controls the display unit 130 to display the results of the search in a local mode UI.
In the case in which the network mode is selected, the control unit 120 searches for all the devices that are connected to the user terminal device 100 via a network with the aid of the network interface unit 110, searches for content from the corresponding devices, and controls the display unit 130 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 the user terminal device 100 from the local mode to the network mode or vice versa. In response to the manipulation of the mode-switching area, the control unit 120 switches the user terminal device 100 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, the control unit 120 controls the display unit 130 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, the control unit 120 controls the display unit 130 to display a UI for the local mode or the network mode not set as default mode.
Referring to
The local mode UI (b) includes an image area 60 in which an image indicating that the user terminal device 100 is in the local mode is displayed, a mode-switching area 70, and an information area 80 in which the number of content items in each content category that are present in the storage unit 140 is displayed.
The mode-switching area 70 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, the user terminal device 100 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.
The information area 80 displays various content categories. For example, referring to
In response to the sliding switch sliding toward the second end of the bar-shaped section, the control unit 120 switches the user terminal device 100 to the network mode, and a network mode UI (c) is displayed on the display unit 130.
The network mode UI (c) has the same configuration as the local mode UI (b). That is, the network mode UI (c) includes an image area 60, a mode-switching area 70, and an information area 80. In the image area 60 of the network mode UI (c), an image indicating that the user terminal device 100 is in the network mode is displayed. The information area 80 of the network mode UI (c) displays the total number of content items that are found from the network of the user terminal device 100, and thus provides different content quantities from the information area 80 of the local mode UI (b). In response to the user terminal device 100 being switched to the network mode, the user terminal device 10 searches for content in real time for a predefined amount of time (for example, less than a second) from the devices 10, 20, 30, and 40 that are connected to the user terminal device 100 via a network, and displays the number of content items in each content category that are found from the devices 10, 20, 30, and 40. The counting of content items is performed during or after the search of content from the devices 10, 20, 30, and 40. The information area 80 of the network mode UI (c) displays the total number of content items found from the devices 10, 20, 30, and 40 after the search of content from the devices 10, 20, 30, and 40, or displays the number of content items that are counted as they are found from the devices 10, 20, 30, and 40 in the course of the search of content from the devices 10, 20, 30, and 40. In the latter, the number of content items in each category is displayed in the information area 80 of the network mode UI (c) as incrementally increasing. In the mode switching area 70 of the network mode UI (c), unlike in the mode switching area 70 of the local mode UI (b), a sliding switch is displayed at a side of the mode switching area 70 corresponding to the network mode.
The user chooses one or more content categories to be displayed in the information area 80 of the local mode UI (b) or the network mode UI (c).
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 in
In the example illustrated in
A plurality of category tabs 81, 82, and 83 is displayed at the top of the list (d) or at the thumbnail view (e). The user selects one of the category tabs 81, 82, and 83 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). The control unit 120 reads out the selected content item from the storage unit 140, 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 the user terminal device 100 or selecting a particular key on the main body of the user terminal device 100 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, the control unit 120 transmits the read-out content item to the target-rendering device via the network interface unit 110.
In network mode, content is provided by various devices connected to the user terminal device 100 via a network. Thus, to allow the user to easily identify the source of each content item, device icons 91 and 92 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 icon 91) representing a mobile phone and an icon (i.e., the device icon 92) 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), the user terminal device 100 is provided with the selected content item from a DMS having the selected content item, and plays the selected content item. For example, the control unit 120 issues a request for the selected content item to the DMS. In response to receiving the selected content item from the DMS, the control unit 120 controls the display unit 130 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, the control unit 120 controls the display unit 130 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, the control unit 120 transmits a control signal to the DMS to request the DMS to transmit the selected content item to the target-rendering device.
Alternatively, the control unit 120 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), the control unit 120 controls the display unit 130 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, the user terminal device 100 serves as a DMC in response to the provision of content to the target-rendering device. That is, the control unit 120 controls the display unit 130 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, the control unit 120 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), the user terminal device 100 is provided with the selected content item from the user terminal device 100 is provided with the selected content item from a DMS having the selected content item, and plays the selected content item. For example, the control unit 120 issues a request for the selected content item to the DMS. In response to receiving the selected content item from the DMS, the control unit 120 controls the display unit 130 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, the control unit 120 controls the display unit 130 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, the control unit 120 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, the user terminal device 100 collects content information relating to each content item that is stored in the storage unit 140.
Alternatively, in network mode, the user terminal device 100 needs to collect content and content information relating to the content from each DMS that is connected to the user terminal device 100 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, the control unit 120 generates a DMS content table, generates a network mode UI based on the DMS content table, and provides the network mode UI to the display unit 130. 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, the user terminal device 100 displays the network mode UI based on previously-loaded content information without the need to perform gathering. Alternatively, if new content is found, the user terminal device 100 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 the user terminal device 100. The control unit 120 performs gathering periodically to collect information necessary for updating.
Since gathering generally takes time, the user often mistakenly determines that the user terminal device 100 is malfunctioning or has stopped operating even when the user terminal device 100 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, the control unit 120 displays a Graphic User Interface (GUI) indicating the progress of gathering on the screen of the user terminal device 100 so that the user easily identifies the progress of gathering.
In
When the gathering operation for the current device is complete, the control unit 120 controls the display unit 130 to apply a graphical effect to the device icon corresponding to the current device, i.e., the device icon 310. For example, when the gathering operation for the current device is complete, the display unit 130 displays one or more content icons 310-1 to 310-5, representing one or more content items that is provided by the current device, along with a graphical effect of the device icon 310 exploding and the content icons 310-1 to 310-5 pouring out of the device icon 310. However, there is no restriction on the type of graphical effect that may be applied by the display unit 310.
When gathering for one device is complete, the control unit 120 initiates gathering for another device. That is, the control unit 120 sequentially performs gathering for one device and gathering for another device. Therefore, when gathering for the current device is complete, the control unit 120 displays a GUI 400 over the device icon 320 corresponding to a subsequent 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, the control unit 120 stops the gathering operation. In this example, the control unit 120 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 the user terminal device 100 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 the user terminal device 100 via a network, the user shares the content present in the user terminal device 100 simply by selecting a content item from the user terminal device 100 and selecting a rendering device to share the selected content item with. In the above-mentioned examples, the local mode is set as default mode. In another example, the network mode is set as default mode.
According to the above-mentioned examples, it is possible to provide not only a local-mode UI and a network-mode UI but also an initial mode and allow at least one of the local mode and the network mode to be realized on the initial UI.
The operation of the user terminal device in local mode and the operation of the user terminal device the network mode have already been described above, and thus, detailed descriptions thereof will be omitted.
Referring to
A mode-switching area is provided on the local mode UI. A user switches the user terminal device from the local mode to network mode by manipulating the mode-switching area.
The user terminal device is maintained in the local mode until switched to the network mode. In step S935, the user selects a content item by using the local mode UI. In step S940, the user also selects a target-rendering device to share the selected content item with by using the local mode UI. In step S945, the user terminal device transmits the selected content item to the target-rendering device.
In step S930, in response to the user terminal device being switched from the local mode to the network mode, one or more devices that are connected to the user terminal device via a network is searched for. In step S955, content is searched for from each of the network-connected devices. In step S960, a network mode UI is displayed. The network mode UI displays the network-connected devices and the content present in each of the network-connected devices.
In step S965, in response to receiving a user command to identify each content item on the network mode UI, the user terminal device performs a gathering operation to collect content information relating to each content item provided by each of the network-connected devices. A GUI indicating the progress of the gathering operation is additionally displayed on a content information list or a thumbnail view.
The content-sharing method illustrated in
In step S970, the user selects a content item from among a number of content items obtained by the gathering operation performed in step S965. In step S975, the user selects a target-rendering device. In step S980, the user terminal device controls the transmission of the selected content item such that the target-rendering device plays the selected content item. The user terminal device is provided with the selected content item from a DMS and provides the selected content item to the target-rendering device. Alternatively, the user terminal device controls the DMS to transmit the selected content item directly to the target-rendering device.
The local mode UI displayed in step S925 and the network mode UI displayed in step S960 both include an information area, as illustrated in
The operation of the user terminal device in local mode and the operation of the user terminal device in network mode have already been described with reference to
According to the example illustrated in
Similarly, a content sharing function is referred to as a DLNA function, a convergence function or the like.
