The present invention, however, may be realized as various types, and is not limited to the exemplary embodiments.

(7) FIG. 1 is a control block diagram of an image processing apparatus 100 according to an exemplary embodiment of the present invention. As shown therein, the image processing apparatus 100 includes a receiver 101, a communicator 103, a signal processor 105, a display unit 107, a user input unit 111, a UI generator 109, a storage unit 113 and a controller 115.

(8) The receiver 101 receives primary image content, and may include a tuning unit (not shown) to receive the primary image content.

(9) The tuning unit may include a single tuner or a plurality of tuners, a demodulator, a decoder, a multiplexer, etc. The tuner tunes a broadcasting signal having a frequency band corresponding to a tuning control signal of the controller 115 (to be described later). The broadcasting signal of the tuned channel is supplied as a transport stream which is packeted by time-division multiplexing a video signal, an audio signal and various data.

(10) For example, if a digital broadcasting signal is received, the demodulator performs vestigial side band (VSB) demodulation and corrects errors with respect to the received broadcast signal, and outputs the transport stream. The tuner includes an analog tuner and a digital tuner to receive both an analog broadcasting signal and a digital broadcasting signal.

(11) The communicator 103 communicates with at least one supply source to request related image content of the primary image content, and receives the related image content from the supply source according to control of the controller 115. The communicator 103 according to the present exemplary embodiment may communicate with the supply source connected through a wired/wireless LAN, modem, etc.

(12) The supply source supplies the primary image content, and may include broadcasting stations (e.g. terrestrial broadcasting stations such as SBS, KBS and MBC, regional broadcasting stations and cable broadcasting stations), and a server storing the primary image content.

(13) As shown in FIG. 2, the communicator 103 according to the present exemplary embodiment communicates with respective broadcasting stations 150, 160 and 170, each of which comprises a server which stores the primary image content therein, and receives the related image content stored in the server of the broadcasting stations 150, 160 and 170. The receiver 101 receives the primary image content supplied by the respective broadcasting stations 150, 160 and 170 in real-time through a radio frequency (RF) signal. The receiver 101 and the communicator 103 may be provided as an integrated chip (IC).

(14) The signal processor 105 processes the primary image content supplied by the communicator 103, and converts the primary image content into a format displayable as an image on the display unit 107, e.g. into a digital RGB signal, and outputs the signal to the display unit 107 under the control of the controller 115.

(15) The signal processor 105 may provide various functions corresponding to the format of the inputted image signal. For example, the signal processor 105 may provide functions such as an analog to digital (A/D) conversion function to convert various types of inputted analog image signals into digital signal in a particular format; a digital decoding function; a scaling function to scale a vertical frequency, resolution, or a picture ratio of an inputted digital image signal and/or analog image signal according to an output protocol of the display unit 107, and a predetermined formation conversion function.

(16) The display unit 107 displays the primary image content processed by the signal processor 105. The display unit 107 may comprise digital light processing (DLP) technology, a liquid crystal display (LCD) and a plasma display panel (PDP). Alternatively, the display unit 107 may be provided as an external unit.

(17) The UI generator 109 generates a user interface (UI) of a list illustrating at least one related image content supplied from the supply source under the control of the controller 115. The UI generator 109 may include an on screen display (OSD) generator or may be included in the signal processor 105 processing the primary image content. The generated UI is outputted and displayed on a part of the display unit 107.

(18) The user input unit 111 includes a key to select a command to play the related image content of the primary image content currently displayed. The user input unit 111 may include a remote controller or a menu key provided on a casing, and a key signal generator to generate a key signal corresponding to key manipulation. The related image content may include titles, content, genres, etc. of the primary image content, which will be described in more detail later.

(19) Particularly, the user input unit 111 according to the present exemplary embodiment may include a hot key to select a command to play the related image content while the received primary image content are displayed. The user input unit 111 may further include a number key and a direction key to select a channel, a function key to select a function provided in the image processing apparatus 100, etc.

(20) The storage unit 113 stores the primary image content processed by the signal processor 105 if the key to play the related image content is selected through the user input unit 111 and the related image content supplied from the supply source are played. The storage unit 113 may comprise at least one of a hard disk, a random access memory (RAM), a flash memory, etc.

(21) If the key used to input the command to play the related image content is selected through the user input unit 111 while the received primary image content is being processed, the controller 115 controls the signal processor 105 to process the related image content supplied from the supply source. The controller 115 may comprise a CPU, a microcomputer, etc.

(22) More particularly, if the primary image content is received through the receiver 101, the controller 115 controls the signal processor 105 to process the received primary image content and display it on the display unit 107. If a channel is selected through the user input unit 111, the controller 115 tunes to the selected channel to receive the primary image content, and processes and displays the received image content.

(23) The controller 115 determines whether the key to play the related image content is selected through the user input unit 111 while the primary image content is processed by the signal processor 105.

(24) The related image content may include image content such as titles, contents, genres, etc. of the currently-processed image content. Preferably but not necessarily, the related image content may include image content broadcast before the currently-viewed image content. For example, if the currently-viewed drama is the fifth episode, the related image content may comprise the fourth, third, second and first episodes.

(25) If the key to play the related image content is selected through the user input unit 111, the controller 115 checks additional information included in the primary image content. The additional information may include a broadcasting station transmitting the image content, the title, contents, playing time, file size of the image content, etc.

(26) The controller 115 requests the broadcasting station transmitting the primary image content, i.e. the supply source through the communicator 103 to supply the related image content, based on the checked additional information. If the supply source transmits the related image content in response to the request, the controller 115 controls the signal processor 105 to process the transmitted related image content to be played.

(27) The controller 115 generates a query to request the list of the related image content to the supply source transmitting the image content, by using the additional information. If the supply source transmits the list of the related image content in response to the query, the controller 115 controls the UI generator 109 to generate a UI of the list.

(28) For example, the related image content may include the previously broadcast image content. In this case, if a user is currently viewing the 17th episode of a drama, a UI A may be generated as shown in FIG. 3. The user may select one of the related image content on the list displayed in the UI A through the direction key provided in the user input unit 111.

(29) If one of the related image content in the UI A is selected through the user input unit 111, the controller 115 controls the communicator 103 to request the supply source to transmit the selected related image content. If the supply source supplies the selected related image content, the controller 115 controls the signal processor 105 to play the supplied related image content.

(30) If the signal processor 105 processes the related image content, the controller 115 controls the storage unit 113 to store the primary image content received by the receiver 101 and processed by the signal processor 105.

(31) Moreover, the controller 115 controls the signal processor 105 to process and display the primary image content stored in the storage unit 113 or controls the UI generator 109 to generate a UI of a list illustrating the stored primary image content if the processing of the related image content is finished.

(32) Thus, a user may select and view the related image content of the currently-viewed primary image content through simple key manipulation. If the related image content of the displayed primary image content is selected, the currently-viewed image content is additionally stored so that a user may view the stored primary image content after viewing the related image content.

(33) A control method of the image processing apparatus 100 according to the exemplary embodiment of the present invention is hereinafter described with reference to FIG. 4.

(34) As shown therein, if the primary image content is received (operation S1), the controller 115 controls the signal processor 105 to process and display the received primary image content (operation S3).

(35) The controller 115 determines whether a user selects the key to play the related image content of the displayed primary image content (operation S5).

(36) If it is determined at operation S5 that the key to play the related image content is selected, the controller 115 requests the supply source supplying the primary image content to transmit the related image content (operation S7).

(37) If the supply source supplies the related image content, the controller 115 controls the signal processor 105 to process and play the related image content (operation S9).

(38) The control method of the image processing apparatus 100 according to the exemplary embodiment of the present invention will be described in more detail with reference to FIG. 5.

(39) As shown in FIG. 5, if the primary image content are received (operation S11), the controller 115 controls the signal processor 105 to process and display the received primary image content (operation S13).

(40) The controller 115 determines whether a user selects the key to play the related image content of the primary image content (operation S15). If the key to play the related image content is selected, the controller 115 requests the supply source to transmit a list of the related image content (operation S17).

(41) The controller 115 checks the additional information included in the primary image content, generates and transmits a query requesting the list of the related image content to the supply source supplying the primary image content, by using the additional information of the image content.

(42) The controller 115 controls the UI generator 109 to generate the UI of the list illustrating the related image content supplied from the supply source (operation S19).

(43) If the related image content selected from the UI through the user input unit 111 is to be played (operation S21), the controller 115 requests the supply source to supply the selected related image content (operation S23).

(44) If the supply source supplies the related image content, the controller 115 controls the signal processor 105 to process and play the supplied related image content (operation S25).

(45) If the related image content is played, the controller 115 controls the storage unit 113 to store the primary image content received by the receiver 101 and processed by the signal processor 105 therein (operation S27).

(46) As described above, the controller 115 may control the signal processor 105 to resume playing the stored primary image content or control the UI generator to generate the UI of the list illustrating the stored primary image content if the playing of the related image content is finished.

(47) Thus, a user may select and view the previously-broadcasted related image content of the currently-viewed primary image content through simple key manipulations. As the image processing apparatus 100 requests the related image content, a user does not need to search the related image content one at a time.

(48) Additionally, if the related image content of the displayed primary image content is selected, the currently-displayed primary image content is additionally stored. Thus, a user may consecutively view the primary image content after viewing the related image content.

(49) As described above, the exemplary embodiment of the present invention provides an image processing apparatus which may be easily manipulated to select and view related image content of currently-viewed primary image content, and a control method thereof.

(50) Additionally, the exemplary embodiment of the present invention provides an image processing apparatus and a control method thereof which automatically requests, receives and displays related image content selected by a user, and improves user's convenience as a user does not need to search the related image content one at a time.

(51) Further, the exemplary embodiment of the present invention provides an image processing apparatus which additionally stores a currently-displayed primary image content if related image content of the displayed primary image content are selected so that a user may consecutively view the primary image content after viewing the related image content, and a control method thereof.

(52) Although a few exemplary embodiments of the present invention 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.
