         [0003]    Aspects of the present invention relate to a method of providing a multimedia content list and a multimedia apparatus applying the method, and more particularly, to a method of providing a multimedia content list including a broadcast program list, and a multimedia apparatus applying the method. 
         [0004]    2. Description of the Related Art 
         [0005]    Broadcast program information is conventionally provided using newspapers, televisions, and/or magazines). However, digital multi-channel broadcasting is provided via scores of channels, giving viewers a choice between a plethora of programs. As a result, the task of selecting programs has become much more complicated. Thus, digital multi-channel broadcasting provides, as a data service, an electronic program guide (EPG) that provides program tables and/or information regarding each program. 
         [0006]    Technological development has enabled users to access a wide range of broadcasts through various channels.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       [0037]    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 embodiments are described below in order to explain the present invention by referring to the figures. 
         [0038]      FIG. 1  is a block diagram of a digital television (DTV) according to an example embodiment of the present invention. Referring to  FIG. 1 , the DTV includes a broadcast receiving unit  110 , a signal separating unit  120 , an audio/video (AN) processing unit  130 , an audio output unit  140 , a graphical user interface (GUI) generating unit  150 , a video output unit  160 , a control unit  170 , a remote control receiver  180 , and a remote controller  190 . 
         [0039]    The broadcast receiving unit  110  receives a broadcast from a broadcast station or a satellite via a cable and/or wirelessly, and demodulates the received broadcast. The signal separating unit  120  separates the demodulated broadcast signal output from the broadcast receiving unit  110  into a video signal, an audio signal, and electronic program guide (EPG) information. The signal separating unit  120  transmits the video signal and the audio signal to the AN processing unit  130 , and the EPG information to the GUI generating unit  150 . 
         [0040]    The A/V processing unit  130  performs signal processing (such as video decoding, video scaling, audio decoding, etc.) on the video signal and the audio signal output from the signal separating unit  120 . Additionally, the A/V processing unit  130  transmits the processed video signal and the processed audio signal to the video output unit  160  and the audio output unit  140 , respectively. The audio output unit  140 , in turn, may output the audio signal transmitted from the A/V processing unit  130  through a speaker of the DTV, or may output the audio signal to an external device (for example, an external speaker) that is connected through an external output terminal 
         [0041]    The GUI generating unit  150  generates a GUI to be provided to a user, and displays the generated GUI (for example, superimposed over video output from the A/V processing unit  130 ). For example, the GUI generating unit  150  may generate a GUI for displaying a multimedia content list using the received EPG information. The multimedia content list corresponds to multimedia content that is viewable by a user (i.e., viewable by the user in the present or in the future). The video output unit  160  may display the video output from the A/V processing unit  130  on a display unit of the DTV, or may output the video to an external device (for example, an external display) that is connected through an external output terminal. 
         [0042]    The remote controller  190  receives user operating commands and transmits the received commands to the DTV via the remote control receiver  180 . The user may input desired keywords and/or may select content on the EPG using the remote controller  190 . 
         [0043]    The control unit  170  recognizes the user operating commands transmitted from the remote controller  190 , and controls the entire operation of the DTV in response to the user operating commands. Specifically, the control unit  170  generates a broadcast content list using the EPG information received from the broadcast station and searches for content associated with one or more keywords input by the user using the input keywords. 
         [0044]    The broadcast content list includes information on the broadcast content (such as the title, time, producer, star, and/or outline of the broadcast content transmitted from the broadcast station, and/or the location at which the broadcast content was filmed). Such information regarding the broadcast content is contained in the EPG information transmitted from the broadcast station. 
         [0045]    Additionally, the control unit  170  controls the GUI generating unit  150  to generate a GUI representing a broadcast content list in which content associated with one or more keywords is distinguished from other content. The control unit  170  displays icons related to the one or more keywords on the broadcast content list, and causes the content associated with the one or more keywords to be distinguished from other content. The control unit  170  displays the icons related to the one or more keywords so that the icons may be connected to areas in which content associated with the one or more keywords is located (hereinafter, referred to as keyword content areas). For example, the control unit  170  may display the icons and the content so that the keyword content areas are connected to the icons with lines or so that the icons are in contact with the keyword content areas in order to indicate that the content is associated with the one or more keywords. In other words, the control unit  170  displays the icons such that the icons are linked to the keyword content areas, so that it is possible to provide the user with an easy way to search for content associated with the one or more keywords. 
         [0046]    Additionally, the control unit  170  may display the keyword content areas differently from other areas on which content other than the content associated with the one or more keywords is displayed, so that the content associated with the one or more keywords is distinguished from other content. For example, the areas may differ in colors and/or font styles (such as a font type, a font size, a font color, etc.). 
         [0047]    Hereinafter, a process by which the control unit  170  provides the broadcast content list will be described in detail with reference to  FIGS. 2 to 5 .  FIG. 2  is a flowchart explaining a process for providing an EPG in which icons are displayed representing content associated with keywords, according to an example embodiment of the present invention. 
         [0048]    Referring to  FIG. 2 , the control unit  170  generates a broadcast content list based on the EPG information in operation S 210 . The control unit  170  receives one or more keywords input by the user using the remote controller  190  in operation S 220 . The user inputs the one or more keywords in order to search for desired programs. For example, the user may input the name of his or her favorite actor and/or his or her favorite genre as keywords. The user may manually input the one or more keywords using character input keys on the remote controller  190 , and/or may select the one or more keywords from a window on which information about a currently broadcast program is displayed. If the user manually inputs keywords using the character input keys on the remote controller  190 , the control unit  170  provides a character input window. 
         [0049]    An example process by which the user manually inputs keywords will now be described. The user selects keyword fields, such as director, star or theme. The user inputs keywords, such as the name of his or her favorite actor or sport. Subsequently, the user determines what form icons indicating the input keywords are to be displayed. The input keywords may be indicated either by a keyword icon in text form, or by a photographic icon in photographic form representing photographs associated with the keywords. The user determines whether to perform an automatic recording function. The user manages the input keywords using a keyword management screen (such as is shown in  FIG. 4 ), which will be described in detail later. 
         [0050]    Alternatively, if the user selects keywords from a window showing information about the currently broadcast program, a keyword registration screen may be used, as illustrated in  FIG. 3 . 
         [0051]      FIG. 3  illustrates the keyword registration screen, according to an example embodiment of the present invention. Referring to  FIG. 3 , the keyword registration screen includes a content display window  310  and a content information window  320 . 
         [0052]    The content display window  310  displays currently viewed broadcast content. The content information window  320  shows information regarding the currently viewed broadcast content. Accordingly, the user may check the information regarding the currently viewed broadcast content (such as information on the title, star, producer, and/or filming location of the currently viewed broadcast content) using the content information window  320 . Additionally, the user may select the information displayed on the content information window  320  to register the selected information as keywords. 
         [0053]    For example, the content information window  320  of  FIG. 3  shows information regarding persons appearing in the currently viewed broadcast content. If the user selects “Ji-hye HAN”  330  from the content information window  320 , the control unit  170  registers “Ji-hye HAN”  330  as a keyword. The user can thereby register keywords using the content information window  320 . Additionally, since the registered keywords are stored in a storage device of the TV, there is no need to further input keywords that have already been registered. 
         [0054]    Referring back to  FIG. 2 , the control unit  170  searches for content associated with the one or more keywords using the EPG information in operation S 230 . Furthermore, the control unit  170  may generate an additional list including the content associated with the one or more keywords found as a result of the search (operation S 230 ). 
         [0055]    Additionally, the control unit  170  may separately provide the keyword management screen with which the user may check the registered keywords. The keyword management screen will now be described in detail with reference to  FIG. 4 . 
         [0056]      FIG. 4  illustrates a keyword management screen, according to an example embodiment of the present invention. In  FIG. 4 , the one or more keywords input by the user are arranged and displayed according to fields in the keyword management screen. 
         [0057]    “Field” on the keyword management screen indicates categories to which keywords belong. For example, in  FIG. 4 , the keywords are classified into “director,” “star,” and “theme” on the keyword management screen. “Keyword” on the keyword management screen indicates keywords registered by the user. “Screen display” on the keyword management screen represents forms of icons displayed together with corresponding content associated with the keywords. For example, “T” shown on “Screen display” indicates that a keyword icon is displayed together with content associated with the corresponding keyword, and a photograph shown on “Screen display” indicates that a photographic icon is displayed together with content associated with the corresponding keyword. The type of icons (such as text icons or photographic icons” may be selected by the user. 
         [0058]    “Automatic recording” on the keyword management screen indicates whether the user desires to perform automatic recording of broadcast content associated with the corresponding keyword. The control unit  170  automatically records broadcast content for which “Yes” is indicated at the corresponding broadcast time. For example, referring to  FIG. 4 , the control unit  170  automatically records broadcast content items corresponding to the keywords “Stanley Kubrick” and “Tennis.” Additionally, the user may select “Input new keyword” to input new keywords. As described above, the user may check which keywords he has inputted, using the keyword management screen. 
         [0059]    Referring back to  FIG. 2 , the control unit  170  determines whether an icon indicating the one or more keywords is set to be a keyword icon in operation S 240 . If it is determined that the icon is set to be a keyword icon (operation S 240 -Y), the control unit  170  displays the keyword icon on the keyword content area on the EPG in operation S 245 . As an example, the control unit  170  displays the keyword icon to contact the keyword content area so that the user can more conveniently know that the corresponding content is associated with the keyword. 
         [0060]    If the icon is set to be a photographic icon in operation S 250 -Y, the control unit  170  displays the photographic icon on the keyword content area of the EPG in operation S 255 . The photographic icon displays an image related to the keyword, and may be selected by the user or may be captured from a scene of the broadcast content. 
         [0061]    Alternatively, if the icon type is not set to be a photographic icon in operation S 250 -N, the control unit  170  receives information regarding the icon type set by the user in operation S 260 . For example, the control unit  170  displays a screen (such as the keyword management screen of  FIG. 4 ) to enable the user to input the icon type. 
         [0062]    Hereinafter, the process described above will be described in detail with reference to an EPG screen shown in  FIG. 5 .  FIG. 5  illustrates an EPG screen in which icons are displayed representing content associated with keywords, according to an example embodiment of the present invention. 
         [0063]    Referring to  FIG. 5 , the EPG screen includes a broadcast content list  510  and a detailed information window  520  to display detailed information regarding broadcast content. If the user selects broadcast content using the remote controller  190 , the control unit  170  displays detailed information regarding the selected broadcast content on the detailed information window  520  on a lower portion of the EPG screen. It is understood that aspects of the present invention are not limited to the detailed information window  520  being located on the lower portion of the EPG screen. For example, the detailed information window may be located on an upper portion of the EPG screen, or elsewhere. The detailed information window  520  displays information regarding the program, producer, star, and filming location, based on EPG information. 
         [0064]    The broadcast content list  510  is displayed according to channels and/or time slots. A vertical axis of the EPG screen shown in  FIG. 5  indicates each channel, and a horizontal axis thereof indicates each time slot. As an example, referring to the broadcast content list  510 , broadcast content entitled “Likable or Not” is broadcast from 20:20 to 20:57 pm. 
         [0065]    Keyword icons or photographic icons are displayed above some content items on the broadcast content list  510 . For example, a keyword icon, “Travel,”  530  is displayed above content entitled, “Special Focus.” Referring to  FIG. 4 , the keyword “Travel” belongs to a field “Theme.” Accordingly, the broadcast content “Special Focus” is a program regarding travel. Additionally, a keyword icon “Ji-hye HAN”  540  is displayed above the content entitled “Likable or Not” on the EPG screen of  FIG. 5 . Referring to  FIG. 4 , the keyword “Ji-hye HAN” belongs to a field “Star,” and the actress “Ji-hye HAN” appears in a program entitled, “Likable or Not.” Furthermore, a photographic icon  550  is displayed above content entitled “ShinHan Bank Pro-League” on the EPG screen of  FIG. 5 . Referring to  FIG. 4 , the photographic icon  550  corresponds to a keyword “Yo-han LIM” belonging to a field “Star.” Accordingly, it is possible to know that Yo-han LIM appears on a program entitled, “ShinHan Bank Pro-League.” As described above, the icons are displayed above or near the corresponding content associated with the corresponding keywords on a screen showing the broadcast content list  510 , so the user can easily check which content is related to the registered keywords. 
         [0066]    The control unit  170  may display a keyword content area indicating content associated with keywords differently from other areas showing content other than the content associated with keywords. The differently displayed areas may be distinguished by colors and/or fonts. 
         [0067]    For example, the background color of the content entitled “Likable or Not,” “Special Focus,” and “ShinHan Bank Pro-League” of  FIG. 5  may be displayed in red, while other content is displayed without the background color. Accordingly, the broadcast content list  510  may be displayed so that the content associated with the keywords is distinguished from other content. 
         [0068]    While a photographic icon is used to represent keywords, it is understood that aspects of the present invention are also applicable to various types of images related to the keywords. For example, keywords may be represented by thumbnail icons or character icons. 
         [0069]    In the example embodiment of the present invention described above, the broadcast content list generated using the EPG information is displayed together with icons. However, it is understood that aspects of the present invention are equally applicable to a multimedia content list (for example, a video-on-demand (VOD) service content list of an Internet protocol (IP) TV or an Internet moving image file list). 
         [0070]    Additionally, while the DTV is applied as a multimedia apparatus according to the exemplary embodiment of the present invention described above, there is no limitation to the type of multimedia apparatus to which aspects of the present invention are applicable. For example, aspects of the present invention are equally applicable to a portable TV, a personal multimedia player (PMP), and a moving picture experts group-1 audio layer 3 (MP3) player. 
         [0071]    As described above, according to aspects of the present invention, a multimedia content list is provided in which content associated with keywords is distinguished from other content, so the user is able to use TV multimedia content more conveniently. Additionally, icons indicating keywords are displayed relative to the content associated with the keywords on an EPG screen, so the user can more easily check a program related to the keywords he has registered. 
         [0072]    Aspects of the present invention can also be embodied as computer-readable codes on a computer-readable recording medium. Also, codes and code segments to accomplish the present invention can be easily construed by programmers skilled in the art to which the present invention pertains. The computer-readable recording medium is any data storage device that can store data which can be thereafter read by a computer system or computer code processing apparatus. Examples of the computer-readable recording medium include read-only memory (ROM), random-access memory (RAM), CD-ROMs, magnetic tapes, floppy disks, and optical data storage devices. The computer-readable recording medium can also be distributed over network-coupled computer systems so that the computer-readable code is stored and executed in a distributed fashion. Aspects of the present invention may also be realized as a data signal embodied in a carrier wave and comprising a program readable by a computer and transmittable over the Internet. 
         [0073]    While there have been illustrated and described what are considered to be example embodiments of the present invention, it will be understood by those skilled in the art and as technology develops that various changes and modifications, may be made, and equivalents may be substituted for elements thereof without departing from the true scope of the present invention. Many modifications, permutations, additions and sub-combinations may be made to adapt the teachings of the present invention to a particular situation without departing from the scope thereof For example, an already-generated broadcast content list may be modified and displayed according to aspects of the present invention (i.e., without generating a new broadcast content list). Furthermore, multiple keywords may be applied to one icon. Accordingly, it is intended, therefore, that the present invention not be limited to the various example embodiments disclosed, but that the present invention includes all embodiments falling within the scope of the appended claims.
