The video output 130 may be implemented as various displays including, without limitation, liquid crystal, plasma, light-emitting diode, organic light-emitting diode, surface-conduction electron-emitter, carbon nano-tube, and nano-crystal.
The video output 130 may further include additional elements depending on implementations of various embodiments. For example, the video output 130 may be implemented as a liquid crystal display, may include a liquid crystal display (LCD) panel, a backlight unit emitting light to the LCD panel and a panel driving substrate which drives the LCD panel.
The video output 130 displays a video thereon based on the video signal processed by the data processor 120. The video output 130 may include a LCD panel, a plasma display panel (PDP), an organic light emitting diode (OLED) panel, etc. to display a video thereon.
The storage 140 may include a writable ROM in which data remains even upon cutoff of power to the electronic device 1, and to reflect any change with respect to a user. That is, the storage 140 may be implemented as one of a flash memory, an erasable programmable read only memory (EPROM) and an electrically erasable programmable read only memory (EEPROM). The storage 140 may store therein setting information related to a video.
The audio output 170 may output an audio signal processed by the data processor 120. The audio output 170 may control an audio with respect to volume and sound by control of controller 100. The audio output 170 may adjust volume and sound according to various sound modes.
In response to the electronic device 1 being initially connected to data source devices 2 to 5 (see
The UI generator 150 may generate a UI to execute an application program. The generated UI includes a plurality of sub UIs which are provided in the form of icons or texts. In response to a user selecting a particular sub UI through the electronic device 1, the application program may be executed corresponding to the selected sub UI. That is, respective sub UIs may be generated for a plurality of functions or events to execute the application program that operates in the electronic device 1.
The UI generator 150 may be implemented as software and/or hardware to generate and control a UI displayed by the video output 130, and such functions may be performed by the controller 100 (to be described later). That is, the UI generator 150 may not be necessarily implemented as an additional chipset or an additional microprocessor. The UI generator 150 may generate a UI to change setting information of a video of the electronic device 1.
The user input 160 transmits preset various control commands or information to the controller 100 by a user's manipulation and input. The user input 160 is implemented as a menu key or an input panel that is installed in an external side of the electronic device 1, or as a remote controller that is separated/spaced from a user terminal. Otherwise, the user input 160 may be integrally formed in the video output 130. If the video output 130 is a touch screen, a user may touch an input menu (not shown) displayed by the video output 130 in order to transmit a preset command to the controller 100.
The user input 160 receives a user's motion. A user's motion includes a touch input. The user input 160 may directly receive a user's motion, or may receive information related to a user's motion from an external device.
The controller 100 may change setting information of at least one of a video and an audio which is transmitted by the data source devices 2 to 5, which corresponds to setting information of at least one of a video and an audio of the electronic device 1. A size of a video frame of a video that is transmitted by the data source devices 2 to 5 may be different from a setting of at least one of a video and an audio related to the electronic device 1. For example, a video frame that is transmitted by the data source devices 2 to 5 is 1280×1024. However, a screen setting of the electronic device 1 regarding a video may be 1920×1080. In such a case, the transmitted video may be displayed in a smaller size rather than being displayed in an entire screen of the video output 130 of the electronic device 1. To prevent the foregoing case, the controller 100 may change the setting of the transmitted video frame from 1280×1024 to 1920×1080 to display the video in the entire screen of the video output 130. A resolution of the transmitted video may be changed contrary to a user's desire, but it may be adjusted by a user. This also applies to an audio signal.
The controller 100 may compare setting information of at least one of a video and an audio, with setting information of at least one of a video and an audio of the electronic device 1. In response to the setting information not being identical, based on the comparison, the controller 100 may change the setting information of at least one of the video and the audio by using the generated UI. By changing the setting information, a transmitted video frame may be enlarged or reduced. A UI may be provided to various setting information. For example, a user may change setting information including sound/resolution/volume/brightness/contrast/chroma, etc., through a UI.
The controller 100 may register the data source devices 2 to 5 by using inherent information of the data source devices 2 to 5 regarding a wireless connection. For example, if a user receives at least one of a video and an audio from a smart phone of his/her friend through a user's smart phone by a wireless communication such as Wi-Fi direct, and if the friend's smart phone is connected to the user's smart phone through Wi-Fi direct, a user may register the friend's smart phone that is connected to a user's smart phone through Wi-Fi direct. The controller 100 may determine whether the wireless connection to the data source devices 2 to 5 is a particular wireless connection, and based on the determination result, may store changed setting information of at least one of a video and an audio of the data source devices 2 to 5. In response to the electronic device 1 being wirelessly connected to the data source devices 2 to 5 and receiving at least one of a video and an audio therefrom, the controller 100 may determine what wireless connection has been used. The controller 100 may store setting information according to connection methods, and in response to the electronic device 1 again being connected to the data source devices 2 to 5 by the same connection method, may output at least one of a video and an audio by using the stored data.

A user changes the setting information of at least one of the video and the audio (S36).
The controller 100 stores the changed setting information corresponding to the registered data source devices 2 to 5 (S37).
In response to determining at operation S34 that the setting information are identical based on the result of the comparison, the operation of displaying the UI and changing and storing the setting information of at least one of the video and the audio is skipped and a next step may be performed. Since a user may set steps, the operation S35 may be performed to display the UI and to change and store the setting information of at least one of the video and the audio.

The controller 100 determines whether the connection of the electronic device 1 to the data source devices 2 to 5 is the particular wireless connection (S45).
In response to determining that the connection of the electronic device 1 to the data source devices 2 to 5 is the particular wireless connection, the changed setting information is stored corresponding to the data source devices 2 to 5 (S46).
Thereafter, the electronic device 1 is secondly connected to the data source devices 2 to 5 again (S47).
The electronic device 1 receives at least one of a video and an audio from the data source devices 2 to 5 (S48).
At least one of the video and the audio is output based on the stored setting information (S49).
In response to determining at operation S45 that the connection of the electronic device 1 to the data source devices 2 to 5 is not the particular wireless connection but rather is a wired connection, setting information related to at least one of the video and the audio of the electronic device 1 is updated (S50). In response to there being no setting information to be updated, an operation S54 is performed to output at least one of the video and the audio.
The updated setting information is stored corresponding to the data source devices 2 to 5 (S51).

The electronic device 1 receives at least one of a video and an audio from the data source devices 2 to 5 (S53).
At least one of the video and the audio is output based on the stored setting information (S54).
For example, the electronic device 1 may be wirelessly connected to a set-top box 2, a smart phone 3, a laptop computer 4 and a computer 5, and may receive a video and an audio therefrom. In response to the electronic device 1 receiving at least one of a video and an audio through a wireless connection and outputs at least one of the video and the audio, the video may be displayed differently from its original state due to a different video size and other various setting information. Since the data source devices 2 to 5 and the electronic device 2 may have different settings for displaying the video, a user should change such settings in order to satisfactorily view video through the electronic device 1.
The electronic device 1 displays the video that is transmitted by the data source devices 2 to 5, based on the original setting of the video, and thus the displayed video may be distorted, and the sound may be distorted as well as the audio and video may not be what a user desires.
After the electronic device 1 is wirelessly connected to one of the set-top box 2, the smart phone 3, the laptop computer 4 and the computer 5, e.g., to the smart phone 3, and receives a video therefrom and displays the video, the video may be displayed in a smaller screen (A) of the electronic device 1 in
Setting information related to a sound may be also changed and stored like the setting information related to the screen. A user may then listen to the sound through a speaker 10 that may be included in the electronic device 1 or may listen to sound from a speaker separated from the electronic device.
In response to the electronic device 1 being connected to the data source devices 2 to 5, the electronic device 1 checks whether the data source devices 2 to 5 are registered with the electronic device 1, and in response to the data sources not being registered, registers the data source devices 2 to 5. The electronic device 1 then stores the setting information related to at least one of a video and an audio, and in response to the same data source devices 2 to 5 being again connected to the electronic device 1, the electronic device 1 uses the stored setting information to output at least one of the video and the audio desired by a user. This prevents a repetitive setting changing process which should be otherwise performed whenever the electronic device 1 receives a video from the data source devices 2 to 5. Therefore, the electronic device 1 may receive at least one of the video and the audio and enable a user to easily and conveniently view the video or listen to the audio.
According to the exemplary embodiments, the electronic device checks whether the data source device is registered with the electronic device when the electronic device is connected to the data source device. In response to a determination that the data source device is not registered with the electronic device, the electronic device registers the data source device, stores setting information related to at least one of a video and an audio, and in response to the data source device again being connected to the electronic device, outputs the video and the audio as desired by a user by using the stored setting information. Since the repetitive setting changing process which should be otherwise performed whenever the electronic device receives a video and an audio from the data source device is prevented, the electronic device may receive the video and the audio and enables a user to easily and conveniently view the video and listen to the audio.
Although a few exemplary embodiments 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 inventive concept, the scope of which is defined in the appended claims and their equivalents.
