     BACKGROUND 
     1. Field 
     The present general inventive concept generally relates to a technology which transmits content between apparatuses and displays the content, and more particularly, to a display apparatus which displays content in an optimal state on a display screen according to a type of content, a source apparatus, and methods of providing content. 
     2. Description of the Related Art 
     In general, a display apparatus such as a digital TV is provided with and displays various types of content, such as moving pictures, photos, games, or the like, through a source apparatus such as a set-top box or through a network. 
     The display apparatus which displays various types of content as described above displays received content without considering or adapting to the type of content that is being displayed. In this case, content including noise is displayed on a screen. 
     Therefore, in order to respectively display the content in optimal screen sizes, a user directly sets screen sizes of each of the content that is received, respectively. Whenever the types of displayed content are changed as described above, the user sets screen sizes appropriate for the changed types of the content. Therefore, after a predetermined use time elapses, the user views the content without setting the screen sizes. As a result, the display apparatus has an application limit. 
     Also, an inexperienced user lacks a basic knowledge of types of content and may be inexperienced in setting of screen sizes and thus cannot view the content in an optimal state.

     DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS 
     Exemplary embodiments will be described in greater detail with reference to the accompanying drawings. 
     In the following description, the same drawing reference numerals are used for the same elements even in different drawings. The matters defined in the description, such as detailed construction and elements, are provided to assist in a comprehensive understanding of the exemplary embodiments. Thus, it is apparent that the exemplary embodiments can be carried out without those specifically defined matters. Also, well-known functions or constructions are not described in detail since they would obscure the exemplary embodiments with unnecessary detail. 
       FIG. 1  is a block diagram of a display apparatus according to an exemplary embodiment. 
     Referring to  FIG. 1 , the display apparatus includes a receiver  110 , a detector  120 , a storage unit  130 , a video processor  141 , and a display unit  150 . 
     The receiver  110  receives content data, and the detector  120  detects content type information of the content data received through the receiver  110 . The storage unit  130  (e.g., a storage) stores frame size information matching with each content type. The video processor  141  forms a content frame having a frame size corresponding to the content type information detected through the detector  120 , by using the frame size information stored in the storage unit  130 . The display unit  150  (e.g., a display) displays the content frame having the frame size adjusted through the video processor  141 . 
     In detail, the receiver  110  may receive content data from at least one of a source apparatus such as a set-top box, a broadcast transmitting apparatus, and an Internet terminal apparatus. Also, the content data may content types related to a graphic, a photo, a moving picture, and a game. If content data of one of the content types related to the graphic, the photo, the moving picture, and the game is received through the receiver  110 , the detector  120  detects content type information of the received content data. In detail, the content data includes content type information of a content which is to be displayed on a screen through the display unit  150 . According to an exemplary embodiment, if content data is received from a source apparatus through a High Definition Multimedia Interface (HDMI), an audio visual interleaved (AVI) infoframe including content type information may be included in the content data. Therefore, the detector  120  may acquire an AVI infoframe from the received content data and detect content type information of a content, which is to be displayed on the screen, from the acquired AVI infoframe. 
     If the content type information is detected through the detector  120  as described above, the video processor  141  acquires frame size information corresponding to the detected content type information with reference to the storage unit  130  which stores the frame size information matching with each of the content types. After that, the video processor  141  forms a content frame having a frame size corresponding to the acquired frame size information. Here, the frame size information of each of the content types stored in the storage unit  130  is set and stored by a user. Therefore, the display apparatus may store the frame size information of each of the content types, which is set by the user through an input unit  170  (e.g., an input) and a controller  180 , in the storage unit  130 . 
     Meanwhile, the storage  130  according to an exemplary embodiment may store scaling information which is matched for each content type. In this case, the video processor  141  may adjust the size of the content to be displayed based on the scaling information stored in the storage  130 . To do so, the video processor  141  may include a scaler (not shown). Specifically, if content type information is detected through the detector  120 , the scaler (not shown) obtains from the storage  130  scaling information corresponding to the content type information detected from the detector  120 . Subsequently, the scaler (not shown) may adjust the size of the content to be displayed based on the obtained scaling information. 
     The input unit  170  receives a setting command. If the setting command is input through the input unit  170 , the controller  180  controls the display unit  150  to display a user interface (UI) which is used to set a frame size of each of the content types. According to an exemplary embodiment, the user may request setting of a frame size of moving picture content. If a command to set the frame size of the moving picture content is input through the input unit  170 , the controller  180  controls the display unit  150  to display a UI which is used to set the frame size of the moving picture content. According to a control command, the display unit  150  displays the UI which is used to set the frame size of the moving picture content. If frame size setting information of the moving picture content is input through the input unit  170  when the UI to set the frame size of the moving picture content is displayed, the controller  180  stores frame size information of a moving picture content type input from the user in the storage unit  130 . 
     If frame size setting information of each of the content types is input from the user through the input unit  170 , the controller  180  may store the frame size information of each of the content types in the storage unit  130 . Therefore, the video processor  141  may acquire frame size information related to the content type information detected by the detector  120  from the storage unit  130  and form a content frame having a frame size corresponding to the acquired frame size information. 
     In detail, if the content type information of the content data is detected as a moving picture content type, the video processor  141  may form a content frame having a frame greater than a size of a display screen of the display unit  150  according to the frame size information of the moving picture content stored in the storage unit  130 . Therefore, as shown in  FIG. 2 , the display unit  150  may display a moving picture content, which is enlarged more than a real moving picture content displayed on the display screen, to display a moving picture content from which noise has been removed. 
       FIG. 2  is a view illustrating a moving picture content which is displayed in a size enlarged according to frame size information in a display apparatus, according to an exemplary embodiment. 
     If content data is received from a source apparatus as on the left side of  FIG. 2 , the video processor  141  forms a content frame from the received content data. If the content frame is formed, the display apparatus  150  may display the corresponding content frame to display moving picture content  220  on a display screen  210 . However, an outer area ‘a’ of the moving picture content  220  displayed on the display screen  210  includes a large amount of noise. Therefore, a user may not view the moving picture content  220  in an optimal state. Therefore, the video processor  141  forms a content frame of the moving picture content  220  in a frame size greater than a size of the display screen  210  of the display unit  150  in order to remove the noise of the outer area ‘a’ of the moving picture content  220 . As a result, as shown on the right side of  FIG. 2 , the display unit  150  may display a remaining area of the moving picture content  220 , except the outer area ‘a’ of the moving picture content  220  including the noise, on the display screen  210 . 
     According to an exemplary embodiment, the user may set the moving picture content  220  to be enlarged within an enlargement range between 0% and 10%. For example, if a setting command with respect to an enlargement condition of 20% from the enlargement range between 0% and 10% is input from the user, the controller  180  stores frame size information set under the enlargement condition of 20% in the storage unit  130 . Therefore, the video processor  141  may form a content frame of the moving picture content  220  corresponding to the frame size information set under the enlargement condition of 20%. As a result, the display unit  150  displays only a content frame corresponding to a size of 98% on the display screen  210 . Therefore, the outer area ‘a’ of the moving picture content  220  enlarged by a size of 2% may be removed from the display screen  210 . 
     If the content type information of the content data is detected as a graphic content type related to a webpage, the video processor  141  may form a content frame having a frame corresponding to the size of the display screen of the display unit  150  according to frame size information of a webpage-related graphic content stored in the storage unit  130 . 
     According to an exemplary embodiment, the user may set the webpage-related graphic content to be enlarged within an enlargement range between 0% and 100%. If a setting command with respect to an enlargement condition of 100% from the enlargement range between 0% and 100% is input from the user, the controller  180  stores frame size information set under the enlargement condition of 100% in the storage unit  130 . Therefore, the video processor  141  may form a content frame of the webpage-related graphic content corresponding to the frame size information set under the enlargement condition of 100%. In other words, the video processor  141  may form a content frame having a frame size corresponding to the size of the display screen with reference to a display area of a window control icon formed on an upper part of a side of the webpage-related graphic content and a vertex area of the display screen. Therefore, the display unit  150  may display the webpage-related graphic content on a whole part of the display screen. 
     According to another exemplary embodiment, the display apparatus may further include an audio processor  143  and an audio output unit  160  (e.g., an audio output). The audio processor  143  detects audio data of the content data received through the receiver  110  to generate an audio signal. The audio output unit  160  outputs the audio signal generated by the audio processor  143  through an output unit such as a speaker. In detail, the audio processor  143  acquires audio setting information related to the audio data of the content data from the storage unit  130  which stores the audio setting information. The audio processor  143  may generate an audio signal having an output characteristic corresponding to the acquired audio setting information. 
     According to an exemplary embodiment, the user may request an audio setting for each type of audio. For example, the user may request an audio setting according to each audio genre and each content type or may request a setting of an equalizer adjustment. If such an audio setting command is input through the input unit  170 , the controller  180  controls the display unit  150  to display a UI which is used to set an audio. According to a control command, the display unit  150  displays the UI which is used to set the audio. If setting information according to each audio genre or each content type, or with respect to an equalizer adjustment is input through the input unit  170  as described above when the UI to set the audio is displayed, the controller  180  stores the audio setting information input from the user in the storage unit  130 . 
     Therefore, if the audio data of the received content data is detected, the audio processor  143  acquires the audio setting information related to the detected audio data from the storage unit  130 . After that, the audio processor  143  may generate and output the audio signal corresponding to the acquired audio setting information. Therefore, the audio output unit  160  may output the audio signal generated by the audio processor  143  through the output unit such as the speaker, so that the user hears audio in various genre forms or audio output forms. 
     The elements of the display apparatus have been described in detail. An operation of transmitting content data from a source apparatus to a display apparatus will now be described in detail. 
       FIG. 3  is a block diagram of a source apparatus which provides content to a display apparatus, according to an exemplary embodiment. 
     Referring to  FIG. 3 , the source apparatus includes an interface unit  310  (e.g., an interface), a determiner  320 , and a controller  330 . The interface unit  310  receives characteristic information of the display apparatus. Here, the characteristic information of the display apparatus may include frame size information set according to each content type in the display apparatus, screen size information of the display apparatus, etc. Therefore, if the characteristic information of the display apparatus is received from the display apparatus through the interface unit  310 , the controller  330  stores the received characteristic information of the display apparatus in a storage unit  340  (e.g., a storage). 
     The determiner  320  determines whether a frame size of a content to be transmitted to the display apparatus is adjustable, by using the characteristic information of the display apparatus stored in the storage unit  340 . If the determiner  320  determines that the frame size of the content is adjustable, the controller  330  controls the interface unit  310  to transmit content data including content type information of the corresponding content to the display apparatus. Here, the content data may be at least one of a content related to a graphic, a photo, and a game and an audio content and may include content type information of each content type. 
     For example, if content data of moving picture content is transmitted through the interface unit  310  according to a request of a user, the determiner  320  checks whether frame size information of the moving picture content exists, with reference to the characteristic information of the display apparatus stored in the storage unit  340 . If it is determined that the frame size information of the moving picture content exists, the determiner  320  determines that a frame size of the moving picture content is adjustable in the display apparatus. If the determiner  320  determines that the frame size of the moving picture content is adjustable, the controller  330  controls the interface unit  310  to transmit content data including content type information of the moving picture content to the display apparatus. According to an exemplary embodiment, if content data is transmitted to the display apparatus through a HDMI, the controller  330  may include an AVI infoframe including the content type information in the content data. Therefore, the display apparatus may detect content type information of a content, which is to be played on a display screen, from the AVI infoframe of the content data. 
     According to another exemplary embodiment, the source apparatus may further include a content processor  350  which adjusts a frame size of content. In detail, if the determiner  320  determines that the frame size of the content to be transmitted to the display apparatus is not adjustable, the controller  330  controls the content processor  350  to adjust the frame size of the content according to a size of a display screen of the display apparatus and a type of the content with reference to the characteristic information of the display apparatus stored in the storage unit  340 . If the frame size of the corresponding content is adjusted by the content processor  350  according to the above control command, the controller  330  controls the interface unit  310  to transmit content data having the adjusted frame size to the display apparatus. 
     For example, if it is determined that the frame size of the moving picture content is not adjustable in the display apparatus, the controller  330  controls the content processor  350  to adjust the frame size of the moving picture content according to the size of the display screen of the display apparatus and a type of the moving picture content. According to the above control command, the content processor  350  may adjust the frame size of the moving picture content so that the moving picture content has a frame greater than the size of the display screen of the display apparatus. In other words, the content processor  350  may enlarge the frame size of the moving picture content to display only an area corresponding to a preset condition from a whole display area of the moving picture content displayed on the display screen of the display apparatus. 
     If the content processor  350  adjusts the frame size of the content as described above, the controller  330  may control the interface unit  310  to transmit content data having the adjusted frame size of the corresponding content to the display apparatus. As described above, the source apparatus may determine whether a frame size of each content type of the display apparatus is adjustable to adjust an unadjustable frame size of a content so that the unadjustable frame size of the corresponding content is appropriate for the size of the display screen of the display apparatus in order to provide the corresponding content to the display apparatus. 
     According to another exemplary embodiment, if the content processor  350  adjusts a frame size of content, the controller  330  may control the interface unit  310  to transmit content data including a message, which acknowledges that the frame size of the corresponding content has been adjusted, to the display apparatus. If the content data including the message, which acknowledges that the frame size of the content has been adjusted, is transmitted to the display apparatus as described above, the user may check that a content displayed in the display apparatus has been adjusted to be appropriate for the display screen of the display apparatus. 
     The elements of the source apparatus which provides content to the display apparatus have been described in detail. A method of providing content in the display apparatus and a method of providing content from the source apparatus to the display apparatus will now be described in detail. 
       FIG. 4  is a flowchart illustrating a method of providing content in the display apparatus, according to an exemplary embodiment. 
     Referring to  FIG. 4 , in operation S 410 , the display apparatus receives content data from at least one of a source apparatus such as a set-top box, a broadcast transmitting apparatus, and an Internet terminal apparatus. Here, the content data may be a content type related to a graphic, a photo, a moving picture, and a game. If content data of one of the content is received, the display apparatus checks whether the received content data includes content type information, in operation S 420 . If it is determined that the received content data does not include the content type information, the display apparatus forms a content frame from the received content data and displays the corresponding content frame on a screen. 
     If it is determined that the received content data includes the content type information, the display apparatus detects the content type information from the content data in operation S 430 . According to an exemplary embodiment, if the content data is received from the source apparatus through a Direct Media Interface (DMI), the content data may include an AVI infoframe including the content type information. Therefore, the display apparatus may acquire the AVI infoframe from the received content data and detect content type information of a content to be displayed on the screen from the acquired AVI infoframe. 
     If the content type information is detected from the received content data as described above, the display apparatus forms a content frame having a frame size corresponding to the detected content type information with reference to a storage unit which stores frame size information matching with each content type, in operation S 440 . Next, the display apparatus displays the content frame in operation S 450 . Here, the frame size information of each content type stored in the storage unit may be set and stored by a user, i.e., may be stored through a method as illustrated in  FIG. 5 . 
       FIG. 5  is a flowchart illustrating a method of storing frame size information of each content type in the display apparatus, according to an exemplary embodiment. 
     Referring to  FIG. 5 , in operation S 510 , the display apparatus receives a setting command from a user. In operation S 520 , the display apparatus displays a UI, which is used to set a frame size of each content type, on a screen. According to an exemplary embodiment, the user may request setting of a frame size of moving picture content. If a setting command to set the frame size of the moving picture content is input, the display apparatus displays a UI which is used to set the frame size of the moving picture content. If frame size setting information of the moving picture content is input when the UI to set the frame size of the moving picture content is displayed, the display apparatus stores frame size information of a moving picture content type input from the user in a storage unit in operation S 530 . 
     If frame size setting information of each content type is input from the user as described above, the display apparatus may store the input frame size information of each content type in the storage unit. If the frame size information of each content type is stored in the storage unit according to a request of the user, the display apparatus may acquire frame size information related content type information from the storage unit and form a content frame having a frame size corresponding to the acquired frame size information through operation S 440  of  FIG. 4 . 
     In further detail, if the content type information of the received content data is detected as a moving picture content type, the display apparatus may form a content frame having a frame greater than a size of a display screen according to the frame size information of the moving picture content stored in the storage unit. Therefore, as described with reference to  FIG. 2 , the display apparatus may display a moving picture content, which is enlarged more than the moving picture content actually displayed on the display screen, to display a moving picture content from which noise has been removed. 
     According to an exemplary embodiment, the user may set the moving picture content to be enlarged within an enlargement range 0% and 10%. Therefore, the display apparatus may form a content frame of the moving picture content corresponding to frame size information set under an enlargement condition of 2%. As a result, the display apparatus may display only a content frame corresponding to a size of 98% on the display screen and may remove an outer area of the moving picture content, which is enlarged by a size of 2%, from the display screen. 
     If the content type information of the received content data is detected as a webpage-related graphic content type, the display apparatus may form a content frame having a frame corresponding to a size of the display screen according to frame size information of a webpage-related graphic content. 
     According to an exemplary embodiment, the user may set the webpage-related graphic content to be enlarged within an enlargement range between 0% and 100%. If a setting command with respect to an enlargement condition of 100% from the enlargement range between 0% and 100% is input from the user, the display apparatus stores frame size information, which is set under the enlargement condition of 100%, in the storage unit. Therefore, the display apparatus may form a content frame of the webpage-related graphic content so that the content frame corresponds to the frame size information set under the enlargement condition of 100%. In other words, the display apparatus may form a content frame having a frame size corresponding to the size of the display screen with reference to a display area of a window control icon formed on an upper part of a side of the webpage-related graphic content and a vertex area of the display screen. Accordingly, the display apparatus may display the webpage-related graphic content on a whole part of the display screen. 
     As described above, the display apparatus may adaptively adjust a screen size of content according to frame setting information set related to content type information of content data to display the content in an optimal state. 
     If the received content data includes audio data, the display apparatus may adjust the audio data through a method illustrated in  FIG. 6 . 
       FIG. 6  is a flowchart illustrating a method of outputting audio data of content data in the display apparatus, according to an exemplary embodiment. 
     Referring to  FIG. 6 , if content data is received through operation S 410  of  FIG. 4 , the display apparatus determines whether the received content data includes audio data. If it is determined that the content data includes the audio data, the display apparatus detects the audio data from the content data in operation S 610 . After that, the display apparatus acquires audio setting information related the audio data of the content data from a storage unit which stores the audio setting information. In operation S 620 , the display apparatus converts the audio data into an audio signal having an output characteristic corresponding to the acquired audio setting information. In operation S 630 , the display apparatus outputs the audio signal through an output unit such as a speaker. 
     According to an exemplary embodiment, a user may request audio setting with respect to each audio type. For example, the user may request audio setting according to each content type or setting of an equalizer adjustment. If an audio setting command as described above is input, the display apparatus displays a UI which is used to set an audio as described above. If setting information with respect to each audio genre, each content type or an equalizer adjustment is input from the user when the UI to set the audio is displayed, the display apparatus stores audio setting information input from the user in the storage unit. 
     Therefore, if the audio data of the received content data is detected, the display apparatus may acquire audio setting information related to the detected audio data and convert the audio data into an audio signal corresponding to the acquired audio setting information. If the audio data is converted into the audio signal corresponding to the audio setting information, the display apparatus may output the audio signal through the output unit such as the speaker. Therefore, the user may hear an audio in various genre forms or an audio output form 
     The method of providing content in the display apparatus has been described in detail. A method of providing content from the source apparatus to the display apparatus will now be described in detail. 
       FIG. 7  is a flowchart illustrating a method of providing content from the source apparatus to the display apparatus according to an exemplary embodiment. 
     Referring to  FIG. 7 , in operation S 710 , the source apparatus receives characteristic information of the display apparatus from the display apparatus and stores the characteristic information. Here, the characteristic information of the display apparatus may include frame size information settings according to each content type by the display apparatus, screen size information of the display apparatus, etc. Therefore, the source apparatus may be connected to the display apparatus to receive the characteristic information of the display apparatus or may receive the characteristic information whenever the characteristic information is updated. If the characteristic information of the display apparatus is received from the display apparatus, the source apparatus stores the characteristic information of the display apparatus in a storage unit. 
     In operation S 720 , the source apparatus checks whether a frame size of a content to be transmitted to the display apparatus is adjustable, by using the characteristic information of the display apparatus stored in the storage unit, in order to transmit the content to the display apparatus according to a request of the user. If it is determined that the frame size of the content is adjustable, the source apparatus transmits content data including content type information of the content to the display apparatus in operation S 730 . Here, the content data may be at least one of a content related to a graphic, a photo, a moving picture, a game, and an audio content and may include content type information of each content type. 
     For example, if the source apparatus transmits content data of moving picture content to the display apparatus according to a request of the user, the source apparatus checks whether frame size information of the moving picture content exists, with reference to the characteristic information of the display apparatus stored in the storage unit. If it is determined that the frame size information of the moving picture content exists, the source apparatus determines that the frame size of the moving picture content is adjustable in the display apparatus. If it is determined that the frame size of the moving picture content is adjustable, the source apparatus transmits content data including content type information of the moving picture content to the display apparatus. 
     According to an exemplary embodiment, if the source apparatus transmits content data to the display apparatus through a HDMI, the source apparatus may include an AVI infoframe including content type information in the content data. Therefore, the display apparatus may detect content type information of a content to be played on a display screen from the AVI infoframe of the content data. 
     If it is determined in operation S 720  that the frame size of the content to be transmitted to the display apparatus is not adjustable, the source apparatus adjusts the frame size of the corresponding content according to a size of the display screen and a type of the correspond content and transmits the content having the adjusted frame size to the display apparatus in operation S 740 . For example, if it is determined that the frame size of the moving picture content is not adjustable in the display apparatus, the source apparatus adjusts the frame size of the moving picture content according to the size of the display screen of the display apparatus and a type of the moving picture content with reference to the characteristic information of the display apparatus stored in the storage unit. After that, the source apparatus may adjust the frame size of the moving picture content so that the moving picture content has a frame greater than the size of the display screen of the display apparatus. In other words, the source apparatus may enlarge the frame size of the moving picture content to display only an area corresponding to a preset condition from a whole display area of the moving picture content displayed on the display screen of the display apparatus. 
     If the frame size of the content is adjusted as described above, the source apparatus transmits content data having the adjusted frame size of the corresponding content to the display apparatus. If the source apparatus determines that a frame size of each content type of the display apparatus is not adjustable, the source apparatus may adjust the frame size of the corresponding content so that the frame size of the corresponding content is appropriate for the size of the display screen of the display apparatus and provide the content having the adjusted frame size to the display apparatus. 
     According to another exemplary embodiment, if a frame size of content is adjusted, the source apparatus may further include a message, which acknowledges that the frame size of the corresponding content has been adjusted, in content data and then transmit the content including the message to the display apparatus. Therefore, the user may check that a content displayed on the display apparatus has been adjusted to be appropriate for the display screen of the display apparatus. 
     The foregoing exemplary embodiments and advantages are merely exemplary and are not to be construed as limiting. The present teaching can be readily applied to other types of apparatuses. Also, the description of the exemplary embodiments is intended to be illustrative, and not to limit the scope of the claims, and many alternatives, modifications, and variations will be apparent to those skilled in the art.
