DETAILED DESCRIPTION OF THE EMBODIMENTS
Reference will now be made in detail to the present embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The example embodiments are described below in order to explain the present invention by referring to the figures.
FIG. 1 is a schematic block diagram of an MP3 player according to an example embodiment of the present invention. It is understood that the MP3 player is provided as an example, and aspects of the present invention are not limited thereto. That is, aspects of the present invention are applicable to any multimedia reproducing or management apparatus. Referring to FIG. 1, the MP3 player includes an interface 110, a storage unit 120, a codec 130, an audio processing unit 140, an audio output unit 145, a video processing unit 150, a graphical user interface (GUI) generation unit 153, a video output unit 155, a control unit 160, and an input unit 170.
The interface unit 110 connects the MP3 player to a content storage device (such as a computer). The MP3 player downloads multimedia files from the content storage device through the interface 110, and uploads multimedia files to the content storage device through the interface 110. The storage unit 120 stores multimedia files (such as music files, video files, and text files), and an operation program to operate the MP3 player.
The codec 130 compresses or decompresses multimedia files. In detail, the codec 130 decompresses a multimedia file stored in the storage unit 120, transmits audio data of the decompressed multimedia file to the audio processing unit 140, and transmits video data of the decompressed multimedia file to the video processing unit 150. The audio processing unit 140 processes an audio signal received from the codec 130. For example, the audio processing unit 140 performs sound processing, noise removal, and equalization. Subsequently, the audio processing unit 140 outputs the processed audio data to the audio output unit 145. The audio output unit 145 outputs the audio data to a speaker or an external device (such as an ear phone or a headset) that is connected through an external output terminal. The video processing unit 150 processes a video signal received from the codec 130. For example, the video processing unit 150 performs video scaling, and subsequently outputs the processed video data to the GUI generation unit 153.
The GUI generation unit 153 generates a GUI to be displayed on the display, and adds the GUI to the video data output from the video processing unit 150. The video output unit 155 displays the GUI-added video output from the GUI generation unit 153 on the display, or outputs the GUI-added video to an external device connected through an external output terminal.
The input unit 170 receives user commands and transmits the user commands to the control unit 160. The input unit 170 may be implemented as key buttons, a wheel, a touch pad, or a touch screen.
The control unit 160 determines the user commands received from the input unit 170, and controls the overall operation of the MP3 player according to the user commands. In particular, the control unit 160 operates the GUI generation unit 153 to generate a GUI in which a list display area is divided into a plurality of areas, related lists are displayed on the areas, and a scroll direction of lists varies according to the plurality of areas. The related lists are a plurality of lists that are displayed on the plurality of areas and have higher and lower relationships therebetween. The plurality of lists may be a list regarding content, a list regarding categories, and/or a list regarding function menus.
The list regarding content is a list of content files stored in the storage unit 120. The list regarding content may express the title of content files as the list. For example, the list regarding music files includes “song 1,” “song 2,” “song 3,” “song 4,” etc. The list regarding categories is a list of categories of the content files. In general, categories may be formed based on the title of a folder including content files and/or metadata of content files. For example, the list regarding categories includes “artist 1,” “artist 2,” “artist 3,” “artist 4,” etc. The list regarding function menus is a list of menus regarding functions of the MP3 player. For example, the list regarding function menus includes “back,” “play,” “volume up,” “volume down,” etc.
The control unit 160 controls the plurality of lists to be displayed in respective different manners. For example, a certain list can be arranged as text in an area, and another list can be arranged as icons in another area. Furthermore, the control unit 160 independently decides a scroll direction of each list based on a ratio of a horizontal length to a vertical length of each area or the manner that each list is displayed. For example, if a horizontal length of a certain area is longer than a vertical length, the control unit 160 may provide the list to be horizontally scrolled. Alternatively, if a vertical length of a certain area is longer than a horizontal length, the control unit 160 may provide the list to be vertically scrolled. In addition, if a list is expressed in text and vertically arranged, the control unit 160 may provide the list to be vertically scrolled. Furthermore, if a list is expressed in icons and arranged in a matrix form, the control unit 160 may provide the list to be horizontally scrolled.
As another example, if the user inputs a mode change command through the input unit 170, the control unit 160 changes a list display mode of the MP3 player between a divided screen mode and a whole screen mode. In the divided screen mode, each of the lists is displayed on a respective area from among a plurality of divided areas. In the whole screen mode, a certain list is displayed on the entire display area. Furthermore, if the MP3 player is changed from the whole screen mode to the divided screen mode, the control unit 160 may firstly display an area for the list that was displayed in the whole screen mode, and then displays other areas. Accordingly, the user can intuitively recognize where the list displayed in the whole screen mode is displayed in the divided screen mode. However, it is understood that aspects of the present invention are not limited to this display method. For example, according to other aspects, the control unit may concurrently display the plurality of divided areas, and/or highlight or otherwise distinguish the area corresponding to the list that was displayed in the whole screen mode.
Hereinafter, the function of the control unit 160 is described in greater detail with reference to FIG. 2. FIG. 2 is a flowchart of a GUI providing method according to an example embodiment of the present invention. Referring to FIG. 2, the control unit 160 displays a certain list in the whole screen mode in operation S210. The certain list is a current list that is displayed on a list display area of the display.
If the user selects a mode change using the input unit 170 (operation S220-Y), the control unit 160 changes a list display mode from the whole screen mode to the divided screen mode in operation S230. That is, the control unit 160 divides the list display area into a first area and a second area.
The control unit 160 displays the certain list on the first area and displays a hierarchically lower list on the second area in operation S240. The hierarchically lower list is a list that belongs to one of the items in the certain list. For example, if the certain list is a list regarding “artist,” and if “artist” includes items “artist 1,” “artist 2,” “artist 3,” and “artist 4,” the hierarchically lower list may be a list regarding “artist 2” and include the albums belonging to “artist 2.” That is, the items of the hierarchically lower list may include “album 1,” “album 2,” “album 3,” etc.
As an example, the control unit 160 controls the certain list on the first area to be displayed in the form of icons and be arranged in the form of a matrix, and controls the hierarchically lower list on the second area to be displayed in the form of text and be vertically arranged. Accordingly, the control unit 160 decides that the first area is horizontally scrolled and the second area is vertically scrolled in operation S250. Following operations S210 through S250, the control unit 160 changes the list display mode from the whole screen mode to the divided screen mode.
The configuration of the display in the divided screen mode is described in greater detail with reference to FIG. 3. FIG. 3 illustrates a display area of a GUI and functions of each of the divided areas according to an example embodiment of the present invention. Referring to FIG. 3, the display screen of the multimedia reproducing or management apparatus includes an information display area 301, a second area 302, a second scroll bar 303, a border line 304, a first area 305, a first scroll bar 306, and a tool bar 307.
The information display area 301 displays simple information on a currently displayed screen. For example, if a current screen relates to listening to music, “music” is displayed. Similarly, if a current screen relates to viewing a movie, “movie” is displayed. The second area 302 displays a hierarchically lower list as described above. The hierarchically lower list displays a list that belongs to one of the items in a certain list displayed on the first area 305. The second scroll bar 303 scrolls the list displayed on the second area 302. The border line 304 displays a border between the second area 302 and the first area 305, and may be moved by manipulation of the user.
The first area 305 displays a certain list as described above. The first scroll bar 306 scrolls the certain list displayed on the first area. The tool bar 307 displays menus to perform diverse functions. For example, as shown in an example screen 310, the tool bar 307 displays buttons “back,” “menu,” “widget,” and “whole.” The “whole” button is a button that changes the list display mode from the divided screen mode to the whole screen mode.
The example screen 310 shows how a list display screen is actually displayed in the divided screen mode. In the example screen 310, the first area 305 displays a list of genres including “genre 1” through “genre 4”, and the second area 302 displays a list of artists including “artist 1” to “artist 3.” In general, since a certain genre includes many artists, the list of genres on the first area 305 is a hierarchically higher list than the list of artists on the second area 302. Furthermore, since the first scroll bar 306 is horizontally provided and the second scroll bar 303 is vertically provided, the scroll directions on the first area 305 and the second area 302 are different. Accordingly, a GUI in which the list display area is divided as in FIG. 3 is displayed.
As described above, the first area 305 and the second area 302 display their respective lists in different manners, so the list displayed on the first area 305 and the list displayed on the second area 302 can be distinctively provided. For example, if both the first area 305 and the second area 302 are displayed in the form of text and vertically arranged, it is difficult for the user to distinguish the first area 305 from the second area 302. However, if the first area 305 and the second area 302 are displayed in different manners, the user can recognize the different lists with greater ease.
Moreover, the user can scroll a desired list more easily by differentiating the scroll direction on the first area 305 and the second area 302. For example, if both the first area 305 and the second area 302 are vertically scrolled, when the user vertically scrolls on, for example, a touch screen to scroll the first area 305, there is a possibility that the list on the second area 302 may be scrolled. However, if the scroll direction of the first area 305 and the second area 302 are different, such a malfunctioning can be prevented.
Though the example embodiment described with reference to FIG. 3 provides a hierarchically lower list above a hierarchically higher list, it is understood that aspects of the present invention are not limited thereto. For example, the hierarchically lower list may be provided below or to a side of the hierarchically higher list, or two displayed lists may not have a hierarchical relation.
Hereinafter, a method of changing a position of the border line is described with reference to FIG. 4. FIG. 4 illustrates a method of changing the position of the border line according to an example embodiment of the present invention. Specifically, FIG. 4 illustrates cases where the ratio of the second area to the first area is 2:2, 3:1, and 1:3. If the display of the multimedia reproducing or management apparatus is implemented as a touch screen, the user can change the position of the border line 304 by a simple touching. Therefore, the user can more conveniently use the multimedia reproducing or management apparatus by more easily adjusting a desired area.
Referring back to FIG. 2, in the divided screen mode, if the user selects one item from the list on the first area (operation S260-Y), the control unit 160 displays a hierarchically lower list of the selected item on the second area in operation S265. For example, in the example screen 310 of FIG. 3, if the user selects “genre 2” displayed on the first area, “genre 2” is highlighted and the artists “artist 1,” “artist 2,” and “artist 3” corresponding to “genre 2” are displayed on the second area. If the user selects one item from the hierarchically lower list on the second area (operation S270-Y), the control unit 160 displays a hierarchically lower list of two classes of the selected item on the first area and the second area, respectively in operation S275. This will be described below in greater detail with reference to FIG. 6. Furthermore, if the user selects a mode change using the input unit 170 (operation S280-Y), the control unit 160 displays a highlighted list from among the first area and the second area in the whole screen mode in operation S285. Following this process, the control unit 160 provides a GUI displaying the lists in the divided screen mode.
Hereinafter, the process of changing the list display mode is described in more detail with reference to FIGS. 5 and 6. As an example, the display of the MP3 is implemented as a touch screen, though it is understood that aspects of the present invention are not limited thereto. For example, separate input keys or devices may be implemented as an input unit. FIG. 5 illustrates screens on which a list display mode is changed according to an example embodiment of the present invention. Referring to FIG. 5, a screen 510 in the whole screen mode displays a divide button 515 as a mode change button on a tool bar. In addition, a screen 520 in the divided screen mode displays a whole button 525 as a mode change button on the tool bar. If the user touches the divide button 515 on the whole screen 510, the control unit 160 changes the screen from the whole screen 510 to the divided screen 520. In addition, if the user touches the whole button 525 on the divided screen 520, the control unit 160 changes the screen from the divided screen 520 to the whole screen 510.
Moreover, one item from a list of texts on the second area is highlighted on the divided screen 520, so if the screen changes to the whole screen 510, the list of texts that is displayed on the second area of the divided screen 520 is displayed on the whole screen 510. That is, if the divided screen mode changes to the whole screen mode, a list that is activated by the user selecting from among the first area and the second area is displayed on the whole screen 510
Hereinafter, the mode change process is described in greater detail with reference to FIG. 6, which illustrates a process of sequentially displaying lists according to an example embodiment of the present invention. FIG. 6 illustrates five example screens 610 to 650 in the whole screen mode, and two example screens 660 to 670 in the divided screen mode. A first whole screen 610 is shown as an initial screen to play back music in the MP3 player or a multimedia reproducing or management apparatus. If the user touches “genres” from the list displayed on the first whole screen 610, a second whole screen 620 including a list of genres is displayed. If the user touches “genre 2” from the list of genres displayed on the second whole screen 620, a third whole screen 630 including a list of artists belonging to “genre 2” is displayed. If the user touches “artist 1” from the list of artists displayed on the third whole screen 630, a fourth whole screen 640 including a list of albums belonging to “artist 1” is displayed. If the user touches “album 1” from the list of albums displayed on the fourth whole screen 640, a fifth whole screen 650 including a list of songs belonging to “album 1” is displayed. As described above, in the whole screen mode, the user selects a desired song through the screens 610 to 650 in five steps.
In the divided screen mode, however, if the user touches “genres” on the first whole screen 610, a first divided screen 660 is displayed. If the user touches “genre 2” on a first area of the first whole screen 610, a list of artists are displayed on a second area of the first whole screen 610. If the user touches “artist 1” on the second area of the first whole screen 610, a list of albums and a list of songs, which are hierarchically lower lists of two classes belonging to “artist 1”, are displayed on the first area and the second area, respectively, of a second divided screen 670. That is, in the divided screen mode, if one item is selected from the list on the second area, hierarchically lower lists of two classes of the selected item are displayed on the first area and the second area, respectively. Therefore, in the divided screen mode, the user selects a desired song through the screens 610, 660, and 670 in three steps.
As described above, the number of screens used to select a desired song in the divided screen mode is lower than the number of screens used to select the desired song in the whole screen mode. Accordingly, in the divided screen mode, the user can find a desired song with greater ease and convenience.
Furthermore, the user can change the list display mode between the whole screen mode and the divided screen mode by touching the “divide” button or the “whole” button. For example, when the first divided screen 660 is displayed and the first area displaying the list of genres is activated (for example, an item in the list of genres is highlighted), the screen 660 changes to the second whole screen 620 displaying the list of genres if the user touches the “whole” button. When the first divided screen 660 is displayed and the second area displaying the list of artists is activated, the screen 620 changes to the third whole screen 630 displaying the list of artists if the user touches the “whole” button. If the user touches the “divide” button from the second whole screen 620 or the third whole screen 630, the screen changes to the first divided screen 660. Following the process described above, the user can display and switch between lists in both the whole screen mode and the divided screen mode.
Hereinafter, graphical effects occurring when the list display mode is changed are described in more detail with reference to FIGS. 7 to 16. FIG. 7 illustrates graphical effects when the second whole screen 620 in FIG. 6 changes the first divided screen 660 in FIG. 6 according to an example embodiment of the present invention. Referring to FIG. 7, when the whole screen mode changes to the divided screen mode, the screen changes in the following order: the second whole screen 620→screen 710→screen 720→screen 730→screen 740→the first divided screen 660. In the divided screen 730, a list of genres on the first area is firstly displayed. The list of genres is the list displayed on the first whole screen 620.
