A panel driver (not shown) drives the display panel to display images, but is not limited thereto.
The storage unit 120 stores information regarding a content according to control by the controller 140. The storage unit 120 may store information regarding first contents when a second content is executed while the first contents are running. The stored information may include the kind of first contents, a time at which the contents are paused, a screen at a time of pausing the contents, and the like. The storage unit 120 may be configured as a storage device including a nonvolatile memory, e.g., a hard disk drive, embedded in the display apparatus 100, but is not limited thereto.
The UI generation unit 130 generates a UI regarding a content. In particular, the UI generation unit 130 may generate and display on display unit 110 a UI regarding the first contents, which are shut down. The UI displayed on the display unit 110 may include a plurality of UIs which respectively correspond to the first contents, and the UIs may be displayed corresponding to respective categories by classifying the contents by category.
Here, the UIs may be displayed as a thumbnail image which corresponds to a screen at a time when the first contents are shut down. Accordingly, a user may easily recognize a layout of the entire screen presented at the time of shutting down the contents, which correspond to the respective UIs.
The controller 140 controls overall operations of the display apparatus 100. The controller 140 may include a control program, a nonvolatile memory, such as a read-only memory (ROM) storing the control program and a flash memory, a volatile memory, such as a random-access memory which at least part of the stored control program is loaded into, and a microprocessor, such as a central processing unit (CPU) running the loaded control program and a micro-control unit (MCU), which are not shown in FIG. 1.
When receiving input of an instruction to execute the second content which is different from the first contents, through a key input unit (not shown) or a remote controller (not shown) provided on the display apparatus 100, while running the first contents, the controller 140 may run the second content and shut down the first contents being executed. Accordingly, only a single content may be run at a given time.
When the first contents are shut down, the controller 140 controls the storage unit 120 to store the information regarding the first contents which were shut down. As described above, the information stored in the storage unit 120 may include the kind of first contents, a time at which the contents are paused, a screen at a time of pausing the contents, and the like.
Further, when the first contents are shut down, the controller 140 may control the UI generation unit 130 to generate the UI regarding the first contents which have been shut down, for display on the display unit 110. The UI regarding the first contents may be displayed as a thumbnail image which corresponds to a screen at a time when the first contents are shut down, with information such as the kind and title of the contents being presented together.
When executing a third content, different from the first contents and the second content, while the second content is running, the controller 140 may perform control to display together, the UI regarding the first contents and a UI regarding the second content. Accordingly, a history of contents run in the display apparatus 100 may be readily identified.
As shown in FIG. 2, UIs corresponding to each category may be inclusively displayed in a contents bar 200. That is, UIs classified by category, e.g., recently viewed channel 210, recently connected Allshare 220, recently used application 230, recently retrieved website 240 and recently connected image source 250, may be displayed. For example, as a broadcast channel, a channel last tuned to based on channel tuning by a tuner is displayed. In multimedia files through Allshare, a last played scene is displayed. A site retrieved the most recently in the history of a web browser is displayed as a website.
As illustrated, a category name of a content, a thumbnail of a screen at a time of shut down and a subtitle of a content may be displayed together. When a user selects a particular UI, a content shut down the most recently or a content executed the most frequently may be run among contents included in the category.
As shown in FIG. 3, UIs respectively corresponding to shut down contents are included in a contents bar 300, being displayed in order of latest shut down. That is, the UIs may be displayed in sequence of channel 7 310, channel 8 320, game A 330, HDMI connected DVD 340 and channel 12 350 in order of latest to earliest shut down contents.
A user may select a UI corresponding to each content through the key input unit or the remote controller to conveniently run the content. Further, when a user pushes a particular button on the key input unit or remote controller, the display apparatus 100 according to an exemplary embodiment may enable immediate execution of a latest run content (channel 7 in FIG. 3). Accordingly, except for a content currently running, a previously executed content is conveniently selected and run, providing convenience to the user.
Alternatively, the controller 140 may control display of a plurality of UIs in the order of execution frequency. That is, as shown in FIG. 3, the UIs corresponding to respective contents may be inclusively displayed in the contents bar 300 in order of highest execution frequency for a particular period of time.
When a user selects a particular UI from among the UIs through the key input unit or remote controller, the controller 140 controls, according to a user input, the running of a content which corresponds to the selected UI. Here, the controller 140 may resume execution of the content from a time of shutting down the previous content. Accordingly, when the user reruns the previously run content after changing a content, the user may conveniently resume the content from a part being run at the time of shut down. In particular, when only a single content is allowed to run due to limitations in hardware, the user may arbitrarily conduct a change of contents.
Hereinafter, a display apparatus 100 according to a second exemplary embodiment is described. Descriptions of the same features as in the first embodiment are omitted for purposes of clarity and conciseness.
A controller 140 classifies contents according to category based on a user history of contents use. The use history corresponds to a list of contents run through the display apparatus 100. The controller 140 controls display UIs in each category on a display unit 110.

The display apparatus 100 according to this exemplary embodiment may be used not only for watching broadcasts but for utilizing various contents. The display apparatus 100 executes contents and displays an image including the contents (S110). When receiving input of an instruction from a user (S120) to run a second content, which is different from the first contents being executed, the display apparatus 100 runs and displays the second content according to the user input (S130) and shuts down the first contents being executed (S140). Accordingly, only a single content may be run at a given time.
When the first contents are shut down, the display apparatus 100 stores information about the shut down first contents (S150) which have been shut down. Here, the stored information may include the kind of first contents, a time at which the contents are paused, a screen at a time of pausing the contents, and the like. The information may be stored in a storage device including a nonvolatile memory, e.g., a hard disk drive, embedded in or communicating with the display apparatus 100.
The display apparatus 100 generates and displays a UI regarding the shut down first contents (S160). Here, the displayed UI may include a plurality of UIs which respectively correspond to the first contents, and each of the UIs may be displayed as a thumbnail image which corresponds to a screen at a time when the first contents are shut down, with information such as the kind and title of the contents being presented together.
When executing a third content, different from the first contents and the second content, while the second content is running, the display apparatus 100 may display together the UI regarding the first contents and a UI regarding the second content. Accordingly, a history of contents run through the display apparatus 100 may be readily identified.
The UIs may be displayed in order of latest shut down or execution frequency, which has been described with reference to FIG. 3.
A user may select a particular UI from among the displayed UIs and run a content which corresponds to the selected UI. Here, the display apparatus 100 may resume execution of the content from a time of shutting down the content. Accordingly, when the user reruns the previously used content after changing a content, the user may conveniently resume the content from a part of the content that was being run at the time of shut down. In particular, when only a single content is allowed to run due to limitations in hardware, the user may arbitrarily conduct a change of contents.
FIG. 5 is a first flowchart illustrating a control process of the display apparatus 100 according to an exemplary embodiment.
The display apparatus 100 executes contents and displays an image including the contents (S210). The display apparatus 100 classifies the contents according to a category based on a user history of contents use (S220). The use history corresponds to a list of contents run through the display apparatus 100.
The display apparatus 100 displays UIs in each category (S130). An illustrative example of displaying UIs has been described above with reference to FIG. 2.
When a UI in a particular category is selected according to a user's input, a content that was most recently shut down may be run among contents included in the category. Alternatively, a content executed that is most frequently may be run among contents included in the category.
Although a few exemplary embodiments have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
