BACKGROUND
1. Field
One or more embodiments described herein relate to a display device.
2. Background
Generally, a television is provided with external input terminals for receiving various inputs from a video 1, a video 2, a component 1, a component 2, and a RGB, as well as a sky wave, that is, a RF (radio frequency) through an antenna. In this state, the television receives video and audio signals from the external input terminals, and outputs image and voice. Accordingly, a user can use various external devices of a VCR, a cable, a game, a DVD, and a set-top box connected with the respective external input terminals.
However, if the user cannot memorize respective connections between the external input terminals and the external devices, the user cannot directly change the external device to a desirable input source. For example, if the user desires to watch the DVD, the user cannot directly change to the corresponding input source. That is, there is requirement for sequentially selecting the respective input sources by using a remote control key, and checking the image according to the selected input source. Also, on inputting the input source, the image of the presently selected input source is displayed on a screen of the television. However, it is impossible for the user to check that the displayed image of the selected input source is outputted from which of the external devices.
In the television according to the related art, the user has to check the external device connected by the input terminal of the television and a signal line, for selection of the desirable input source.

DETAILED DESCRIPTION
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
FIG. 1 illustrates a display device (e.g., a television system) having an input source labeling function according to the present invention. As shown in FIG. 1, a tuner 21 tunes a terrestrial or cable broadcasting signal. Then, an audio/video switch 22 receives audio and video signals (AV signals) from various AV input sources (external devices), as well as the turned signal outputted from the tuner 21, and selects any one among the received signals, and then outputs the selected signal. For example, the audio/video switch 22 selects one of the AV signals from a VCR (video cassette recorder), a cable box, a video game system, a DVD (digital video disc) player, a set-top box, a camcorder, and a computer, and then outputs the selected signal. The signals received by the audio/video switch 22 include at least one of video, voice, supplemental information, and text data.
A controller 27 displays a menu for labeling the AV input sources on a display unit 25. Also, if a user inputs representative identifications (IDs) of the AV input sources and a system information of the AV input sources, the controller 27 stores the inputted the representative identifications and the system information in a memory 26. For example, the system information of the AV input sources includes a system type, a manufacturer, a serial number, and a format of data outputted from the AV input source.
In addition, a user interface 28 receives a user's command, and transmits the user's command to the controller 27. The user interface 28 may be a remote controller or a key panel of the display device. The memory 26 stores the representative identifications of the AV input sources, and/or the system information of the AV input sources.
A signal processor 23 receives the AV signal outputted from the audio/video switch 22, and converts the signal to image and sound. That is, the signal processor 23 divides the received signal into a video signal and an audio signal, and it converts the video signal to a displayable image signal and converts the audio signal to a signal suitable for being outputting through a speaker 24. The signal processor 23 may include a video processor and an audio processor in order to perform these functions.
The display device according to the present invention includes a plurality of input terminals connected with the external AV input sources. For example, the display device according to the present invention, includes at least one of a video input terminal, a component input terminal, and an RGB input terminal, at the rear thereof, and includes a front input terminal at the front thereof. The input terminals are respectively connected with the external AV input sources, and the input terminals transmit the signals outputted from the external input sources to audio/video switch 22.
An AV input source labeling method according to the present invention will be described as follows. FIG. 2 illustrates a flow chart of illustrating the AV input source labeling method according to the present invention.
The controller 27 determines whether the user selects a menu key of the user interface 28 (S31). In this case, if the user selects the menu key, a menu window of an OSD (on screen display) type is displayed (S32).
Next, the controller 27 determines whether the user selects an option (Aux. Label) for labeling the AV input sources connected to the display device from the menu window (S33). If the user selects the option (Aux. Label), the controller 27 reads input terminal information stored in the memory 26. The input terminal information includes titles of the input terminals, a data format suitable for the input terminals, and a kind of the external AV input sources suitable for the input terminal.
After selecting the option (Aux. Label) for labeling the input sources, as illustrated in FIG. 3, the controller 27 displays an input source label menu on a screen. The input source label menu includes a list of options for selecting one of pre-stored representative identifications of the AV input sources corresponding to the input terminals and an input field for manually inputting the representative identifications of the AV input sources corresponding to the input terminals. For example, the input source label menu includes a list of the input terminals such as a video 1, a video 2, a front video, a component 1, a component 2, and an RGB, and also includes the option list for selecting the external AV input sources (VCR, cable box, game, DVD, set-top box, computer, etc.). Also, the controller 27 may display the input terminal information.
FIG. 4 illustrates the representative identifications selected or inputted for each AV input source. Referring to FIG. 4, it is possible for the user to select or input the representative identifications corresponding to the input terminals on the input source label menu by using the remote controller or the key panel of the display device. Also, the user may input the system information of the AV input sources by using the input source label menu. The system information of the AV input sources includes the class of the external device, the name of manufacturing company, the serial number, and the format of data outputted from the AV input sources.
On selecting the representative identifications of the AV input sources (S36), the user selects an option (Menu Prev.) for storing the selected representative identifications of the AV input sources and the system information of the AV input sources. After selecting the option (Menu Prev.), the controller 27 generates label information inclusive of the representative identifications and the system information of the AV input sources, and then stores the label information in the memory 26 (S36).
As described above, after labeling the AV input sources, the user may check or change the labeled AV input sources. If the user selects a main input option, the controller 27 reads the label information stored in the memory 26, and then displays a list of the labeled AV input sources on the screen, on the basis of the label information, as shown in FIG. 5.
After labeling the AV input sources, the user may change the AV input sources providing the A/V signal during watching broadcasting. For example, the user selects the menu key of the user interface 28, as shown in FIG. 5, the controller 27 displays the list of the labeled AV input sources on the screen. Then, if the user selects one desirable AV input source from the list of the labeled AV input sources (S37), as shown in FIG. 6, the controller 27 displays the image outputted from the selected AV input source on the screen, and simultaneously, displays the representative identification (VCR) of the selected AV input source corresponding to the input terminal (Video 1) on one portion of the screen (S38). In this state, the corresponding input terminal (video 1) and the system information of the selected AV input source are also displayed on the screen. The representative identification (VCR) of the selected AV input source may be displayed on the screen during a predetermined time period, or may be displayed on the screen during an entire time period for displaying the image of the selected AV input source. If the representative identification of the AV input source is not displayed on the screen during playing the image of the selected AV input source, the user may select a confirmation key in order to display the representative identification of the selected AV input source on the screen.
Also, the user may use a hot key of the user interface 28 in order to display the representative identifications of the AV input sources along with the images of the AV input sources in sequence on the screen.
