According to an exemplary embodiment, an augmented remote controller may identify an object around a user (or about a user) and provide information related to the identified object to the user, thereby offering an augmented reality environment to the user. The object around the user may be an image display apparatus that is controllable using the augmented remote controller, an external device connected to the image display apparatus, contents available from the image display apparatus or the external device, and/or other types of objects.
The augmented remote controller may identify an object around the user by collecting user-related information. For example, the augmented remote controller may collect information regarding location or bearing of the user using a Global Positioning System (GPS) or a compass. Further, the augmented remote controller may capture an image of a real environment of the user by a camera and thus identify an object around the user. The augmented remote controller may also identify an object around the user using a Radio Frequency IDentification (RFID) reader.
The augmented remote controller may identify an object around the user, search for information related to the identified object, and display the detected (or determined) information. The type of the detected information may correspond to the type of the identified object.
For example, when the augmented remote controller identifies an image display apparatus or an external device around the user, it may search for information regarding a content list available from the image display apparatus or the external device. Additionally, the augmented remote controller may search for information regarding a user interface through which the image display apparatus or the external device can be controlled. The augmented remote controller may display the detected information regarding the image display apparatus or the external device to the user.
The augmented remote controller may identify contents provided by an image display apparatus or an external device around the user. The augmented remote controller may search for information regarding contents and display determined information to the user. The augmented remote controller may display a user interface through which the user can edit, play back, and/or transmit contents provided by the image display or the external device.
The augmented remote controller may identify any other type of object around the user (or about the user). For example, the user may capture an image of a piece of furniture around the user using a camera provided in the augmented remote controller. The augmented remote controller may identify that the object captured by the camera is a piece of furniture, referring to a database that stores information regarding images of a number of objects. The augmented remote controller may search for information regarding the furniture, such as name or manufacturer of the furniture, and display the detected information to the user.
The augmented remote controller may augment a real image captured by the camera with detected information regarding an object captured by the camera. For example, the augmented remote controller may display a real image captured by the camera on a display, search for information regarding an object included in the displayed real image, and display the determined information regarding the object on the display using a pop-up window or an icon. Additionally, the augmented remote controller may display the determined information regarding the object as an image or as text on the display.
The user may view the real image augmented with the information detected by the augmented remote controller, through the augmented remote controller. The user may identify information regarding the real image or an object included in the real image by the augmented information overlaid on the real image captured by the camera.
If the display that displays the augmented real image is a touch screen, the user may interact with the augmented remote controller by selecting a pop-up window, an icon, an image, and/or text representing the augmented information. For example, when the user selects a pop-up window representing first augmented information, the augmented remote controller may execute an application related to the first augmented information. The application may be an application that controls an object such as an image display apparatus or an external device included in the augmented real image.
If the augmented remote controller uses a transparent display, the augmented remote controller may display augmented information overlaid on a real image projected onto the transparent display. The augmented remote controller may search for information regarding an object included in the displayed real image and display the determined information as augmented information on the transparent display.
The augmented remote controller may wirelessly transmit signals to and receive signals from an image display apparatus or an external device connectable to the image display apparatus. The user may control the image display apparatus or the external device using the augmented remote controller. The augmented remote controller may receive information regarding operation status of the image display apparatus or the external device and display the received information on the display.
The augmented remote controller may be connected to a network including the Internet. The augmented remote controller may search for information regarding an identified object through the network and display the detected information on the display.

The demodulator 171 may demodulate a broadcast signal received from the broadcast signal receiver 110. For example, the demodulator 171 may receive a digital IF signal DIF from the broadcast signal receiver 110 and demodulate the digital IF signal DIF. The demodulator 171 may also perform channel decoding. For channel decoding, the demodulator 171 may include a convolutional decoder (not shown), a deinterleaver (not shown) and a Reed-Solomon decoder (not shown) and perform convolutional decoding, de-interleaving and Reed-Solomon decoding.
The demodulator 171 may perform demodulation and channel decoding on the digital IF signal received from the broadcast signal receiver 110, thereby obtaining a stream signal TS. The stream signal TS may be a signal in which a video signal, an audio signal and/or a data signal are multiplexed. For example, the stream signal TS may be an Moving Picture Experts Group-2 (MPEG-2) Transport Stream (TS) signal obtained by multiplexing an MPEG-2 video signal and a Dolby AC-3 audio signal. The MPEG-2 TS signal may include a 4-byte header and a 184-byte payload.
In order to properly handle not only ATSC signals but also DVB signals, the demodulator 171 may include an ATSC demodulator and a DVB demodulator. The demodulator 171 may output the stream signal TS to the DEMUX 172.
The DEMUX 172 may demultiplex the stream signal TS, for example, an MPEG-2 TS into an audio signal, a video signal, and a data signal. The DEMUX 172 may receive the stream signal from the demodulator 171, the network interface 120, or the external device I/O unit 130.
The data signal obtained by demultiplexing the input stream signal may be a coded data signal. The coded data signal may include Electronic Program Guide (EPG) information that provides broadcasting information such as titles and start and end times of broadcast programs played on each broadcast channel. For example, the EPG information may be ATSC-Program and System Information Protocol (TSC-PSIP) information in case of ATSC, whereas it may be DVB-Service Information (DVB-SI) in case of DVB.
The decoder 173 may decode the demultiplexed signals. In this exemplary embodiment, the decoder 173 may include a video decoder for decoding the demultiplexed video signal, and a scaler for controlling resolution of the decoded video signal to a resolution level at which the decoded video signal can be output in the image display apparatus 100.
In accordance with an exemplary embodiment, the A/V processor 170 may further include a mixer for mixing an external video signal input to the image display apparatus 100 with a video signal generated from the user interlace controller. While the mixer may be incorporated into the formatter 175 in function, the mixer may be described herein as being separate from the formatter 175, for ease of convenience. The display 180 may display an image based on a mixed video signal. The mixer may output the mixed video signal to the formatter 175.
The formatter 175 may identify a format of the mixed video signal referring to a data signal related to the video signal. The formatter 175 may convert the video signal to a format suitable for the display 180 and output the converted video signal to the display 180.
In this exemplary embodiment, the image display apparatus 100 may display a 3D image on the display 180. The formatter 175 may create a 3D video signal in a predetermined format by separating the mixed video signal into multi-viewpoint image signals and may output the 3D video signal to the display 180. The display 180 may display a 3D image based on the 3D video signal.
A 3D image may be formed with multi-viewpoint images. The user may view the multi-viewpoint images with his or her left and right eyes. Disparity between the multi-viewpoint images viewed by the left and right eyes may provide the illusion of 3D to the user. The multi-viewpoint images that form the 3D image are a left-eye image perceivable to the left eye and a right-eye image perceivable to the right eye.
The format of a 3D video signal may be determined according to the layout of the left-eye and right-eye images of the 3D video signal. The left-eye and right-eye images may be provided on the left and right sides, respectively. This may be called a side by side format. The left-eye and right-eye images may be arranged vertically in a top-down format. A time-division layout of the left-eye and right-eye images may be called a frame sequential format. The left-eye and right-eye images may alternate with each other line by line. This may be called an interlaced format. The left-eye and right-eye images may be mixed in the form of boxes in a checker box format.
A video signal included in an external signal input to the image display apparatus 100 and a GUI video signal created from the user interface controller may be 3D video signals in which 3D images are realized. The mixer may mix these 3D video signals and output the mixed 3D video signal to the formatter 175.
The formatter 175 may identify the format of the mixed 3D video signal referring to a related data signal. The formatter 175 may process the 3D video signal according to the identified format and output the processed 3D video signal to the display 180. If limited 3D image formats are available to the display 180, the formatter 175 may convert the received 3D video signal to a 3D image format in which the display 180 can display a 3D image and output the converted 3D video signal to the display 180.
If the formatter 175 fails to identify the format of the mixed video signal referring to the related data signal, it may use a predetermined algorithm to thereby identify the format. For example, the formatter 175 may identify the format of an input 3D video signal by analyzing edges of an image created based on the input 3D video signal.
If the input mixed video signal is a 2D video signal that allows 2D visualization, the formatter 175 may generate a 3D video signal using a 2D-3D conversion algorithm.

The augmented remote controller 200 may identify or determine a content provided by the image display apparatus 100 or the external device 200 using metadata received from the image display apparatus 100, the external device 30, and/or the home server 50. That is, if an identification device such as the camera or the RFID reader provided in the augmented remote controller 200 points to the image display apparatus 100, the augmented remote controller 200 may identify or determine the image display apparatus 100 playing a content that the user wants to be identified and the augmented remote controller 200 may then identify the content being played in the image display apparatus 100 by using metadata related to the image display apparatus 100.
Additionally, the user may select a person for identification. In this example, the augmented remote controller 200 may read the face, the finger print, and/or the iris of the person by use of a camera, a finger print identifier, an iris identifier in the identification unit 250. The augmented remote controller 200 may identify the person by comparing the read information with information regarding the faces, finger prints, and/or irises of persons stored in a database.
The augmented remote controller 200 may also recognize a person from a voice input of the person.
The user may also select an object around him or her (e.g. a building, furniture, etc.). In this example, the augmented remote controller 200 may collect information regarding location or bearing of the user by GPS or compass. The augmented remote controller 200 may also capture an image of the object using the camera and identify the captured object, referring to image information regarding objects corresponding to the current user location or bearing in the database that stores information regarding objects by user location and bearing.
Information that the augmented remote controller 200 refers to for identifying an object may be stored in the image display apparatus 100, the external device 30, the storage 220 of the augmented remote controller 200, the home server 50, and/or the network server 300. Thus, the augmented remote controller 200 may search for information regarding an identified object in the image display apparatus 100, the external device 30, the storage 220 of the augmented remote controller 200, the home server 50, and/or the network server 300.
For example, when the augmented remote controller 200 identifies or determines the image display apparatus 100 or the external device 30, the augmented remote controller may search for a list of contents being played in the image display apparatus 100 or the external device 30. The augmented remote controller 200 may also search for a list of contents stored in the image display apparatus 100 or the external device 30. Additionally, the augmented remote controller 200 may search for information regarding a broadcast signal received at the image display apparatus 100. The augmented remote controller 200 may also search for information including menus with which to control the image display apparatus 100 or the external device 30.
When the augmented remote controller 200 identifies or determines a content being played or stored in the image display apparatus 100 or the external device 30, the augmented remote controller 200 may search for information related to the content. The content-related information may be a title of the content, shopping information for the content, etc.
If the augmented remote controller 200 identifies or determines a person, the augmented remote controller 200 may search for information regarding the person. The person-related information may specify a name, a age, a job and/or a phone number of the person, contents that the person prefers, and/or a history of contents that the person has viewed.
If the augmented remote controller 200 identifies or determines a real object around the user (e.g. a building, furniture, etc.), the augmented remote controller 200 may search for information related to the object. The object-related information may specify name, manufacturer, price, store, and/or use guide of the object.
The augmented remote controller 200 may display the detected information on the display 260. The detected information may be displayed in a pop-up window or as an icon. The detected information may be displayed as an image or as text. The augmented remote controller 200 may display the detected augmented information superimposed on an image captured by the camera.
The controller 280 may configure a screen of the display 260 such that determined information does not overlap with an object corresponding to the detected information from among the objects included in the real environment of the user. When displaying augmented information on the transparent display, the controller 280 may also configure a screen of the display 260 such that the augmented information is displayed without overlapping with an object corresponding to the augmented information.
As shown in
In this exemplary embodiment, the object 1001 identified by the augmented remote controller 200 is a real image of an object captured by the camera of the augmented remote controller 200. The object-related information 1002 and 1003 is augmented information including information detected by the augmented remote controller 200. As shown in

As shown in
According to the exemplary embodiment shown in
An operation for identifying or determining an external device may be performed along with an operation for generating a preview image by capturing the external device in the augmented remote controller 200. Accordingly, the augmented remote controller 200 may include the identification unit 250 such as a module for identifying an object, generating a preview image of the object, capturing an image, and storing the captured image. The augmented remote controller 200 may also include the display 260 for displaying and storing the preview image or stored image in real time.
The identification unit 250 of the augmented remote controller 200 may identify or determine an external device by an RFID tag. The augmented remote controller 200 may read or acquire external device identification information such as the serial number or product code of the external device. The augmented remote controller 200 may also use image data generated by capturing the external device to identify the external device. The image data may be streamed preview image data or image data that has been captured and stored.
The augmented remote controller 200 may search, in operation S820, for information regarding a content to be played back in the image display apparatus 100 (hereafter referred to as content information). A searched database, in which the content information is searched, may be stored in the image display apparatus 100 or in a server accessible to the augmented remote controller 200 over a wireless communication network. The server may be the above-described network server 300 or home server 40, for example. If the content is a video received from a broadcasting station, the broadcasting station may transmit the content information along with the content to the image display apparatus 100 or the augmented remote controller 200.
The determined content information may be customized for the user of the image display apparatus 100. That is, content information edited or amended to be suitable for the user of the image display apparatus 100 from among the content information regarding the image display apparatus 100 may be a target to be searched for and received. Personalized content information and an associated personalized content guide image may be described below in detail with reference to
The augmented remote controller 200 may receive the determined content information through the wireless communication module 210 in operation S830. If the augmented remote controller 200 detects or determines the content information from the content information database stored in the network server 300 or the home server 50, the augmented remote controller 200 may download the content information from the network server 300 or the home server 50.
The controller 280 of the augmented remote controller 200 may generate a content guide image based on the received content information. The display 260 of the augmented remote controller 200 may then display the content guide image in operation S840. Along with the content guide image, an image of the identified image display apparatus 100 and an image corresponding to the content being played back in the image display apparatus 100 may be displayed on the display 260.
As shown in
The user authentication may be carried out in various manners. For example, the augmented remote controller 200 may identify or determine a face of a user by the camera of the identification unit 250. That is, the augmented remote controller 200 may generate image data regarding the face of the user. The augmented remote controller 200 may search for a user matching a pattern of the face by comparing the image data about the face of the user with image data about users' faces stored in a database, thus performing the user authentication. In the presence of the matching image data, the user authentication may be successful. On the other hand, in the absence of the matching image data, the user authentication may fail.
Alternatively or additionally, a predetermined signal (such as a password) may be used for the user authentication. More specifically, the augmented remote controller 200 may receive a password from a user through the user interface 230, the sensor unit 240, and/or the identification unit 250 in advance and store the password in the storage 220. Thereafter, upon receipt of a security signal from the user through the user interface 230, the sensor unit 240, and/or the identification unit 250, the controller 280 may compare the received security signal with the stored password. Only if the received security signal is identical to the stored password, the controller 280 may determine that the user authentication is successful.
Besides a text signal (such as a security number or password), the security signal may take the form of a voice signal, a finger print image, and/or the like. The same thing may apply to the pre-stored password. Voice-based user recognition may include both authenticating a user by analyzing voice features of the user and authenticating a user by recognizing a message that the user tells. The controller 280 of the augmented remote controller 200 may carry out user authentication by finger print recognition, iris recognition, voice recognition, and/or user's gesture sensing.
If the user authentication is successful in operation S920, the augmented remote controller 200 may search, in operation S930, for personalized content information which is related to the image display apparatus 100 or a content being played back in the image display apparatus. For example, the augmented remote controller 200 may search for information regarding a preferred channel registered by the user or information regarding a channel set for the user. When the user has already set an information category from among information available as content information, only content information that falls into the category may be searched for. For example, it is assumed that contents are stored in the image display apparatus 100 and the user has designated file format, file name, and saved date as search categories. In this example, when the augmented remote controller 200 searches for content information after the user authentication, the augmented remote controller 200 may search only information about file formats, file names, and saved dates of the stored contents.
The augmented remote controller 200 may search for appropriate content information according to the identified image display apparatus 100, success or failure of the user authentication, and/or the identified user, and then receive search results in operation S940.
If the user authentication fails in operation S920, an operation of the image display apparatus 100 or the augmented remote controller 200 may end, while a function not related to the personalized information may continue in operation S950. For example, the augmented remote controller 200 may provide the user that has failed in the user authentication with content information according to a default setting, irrespective of personalized settings for the user. Thus content information that the user has set as locked (or in a locked status) and content information that the user has not requested are not provided. In
The augmented remote controller 200 may display, in operation S970, a content guide image based on the received content information. When searching for and receiving personalized content information after the user authentication, the augmented remote controller 200 may provide a personalized content guide image. The arrangement of the content information included in the content guide image or settings of the content guide image as well as the content information itself may vary according to the user's personalized information. The augmented remote controller 200 may display, on the display 260, information about a preferred channel set for the user or information regarding a channel released from a locked state.
The above operation may be summarized, by an example. If the image display apparatus 100 is displaying an EPG or a channel browser, the augmented remote controller 200 may identify the displaying of the EPG or channel browser in the image display apparatus 100 and search for personalized data related to the EPG or the channel browser. In an exemplary embodiment, personalized data may be information regarding preferred contents registered according to the user, or information regarding locked content or unlocked contents for the user. Accordingly, the personalized data related to the EPG or the channel browser may be information regarding a preferred channel set for the user or a channel set as locked or released from the locked state. After the user authentication by face recognition, etc. for example, the augmented remote controller 200 may display, on the display 260, information regarding a preferred channel set by the user or information regarding a channel set to be displayed for the user.
As shown in
If the augmented remote controller 200 accesses the network server 300, the wireless communication module 210 may be connected to the network server 300 over an IP network. If the augmented remote controller 200 accesses the home server 50, the wireless communication module 210 may be connected to the home server 50 over the home network 40. It is assumed that a database of content information may be stored in the network server 300 or the homer server 50.
After accessing the server, the augmented remote controller 200 may search, in operation S1030, for content information related to the identified image display apparatus 100. If a user has already been identified or authenticated, the controller 280 of the augmented remote controller 200 may search for personalized content information for the user. Identification information of the identified image display apparatus 100 and/or identification information of the user may be used in searching for the content information or the personalized content information. Additionally, if there is a past history of searching for content information and displaying a content guide image in relation to the same image display apparatus 100 and/or the same content, the previous content guide image may exist in the database of content information. In this example, the augmented remote controller 200 may search for and receive the same content guide image.
The augmented remote controller 200 may receive, in operation S1040, the detected content information, the personalized content information, and/or the content guide image through the wireless communication module 210. The augmented remote controller 200 may display, in operation S1050, the content guide image based on the received information on the display 260.
As shown in
The augmented remote controller 200 may determine, in operation S1120, whether the image display apparatus 100 is on or off. It may be determined in various manners whether the image display apparatus 100 is on or off. For example, in absence of a signal received from the image display apparatus 100 or in absence of metadata received through the image display apparatus 100, the augmented remote controller 200 may determine that the image display apparatus 100 is off. To determine that the image display apparatus 100 is off in the example where non-signal transmission and reception lasts for a predetermined time or longer, a timer may be used. The augmented remote controller 200 may determine the power-off of the image display apparatus 100 by analyzing an image of the image display apparatus 100 captured by the camera. The determination as to the power-on or the power-off of the image display apparatus 100 may also be made through the home server 50.
In the example of the power-off of the image display apparatus 100, the augmented remote controller 200 may access the home server 50 through the wireless communication module 210 in operation S1130. In this exemplary embodiment, the augmented remote controller 200 may search for content information for a user of the image display apparatus 100 in the power-off state in the home server 50. The content information is information regarding a content played back in the image display apparatus 100. This content information may be personalized information for the user that has been identified or authenticated. A user identification operation may be performed before accessing the server. The augmented remote controller 200 may search for the content information in the home server 50 and receive the determined content information from the homer server 50 in operation S1140. If the image display apparatus 100 is powered-on, the augmented remote controller 200 may search for the content information through the image display apparatus 100 in operation S1150. The content information may be searched for through the home server 50 or the network server 300 in operation S1150.
Upon receipt of the content information for the user from the image display apparatus 100 or the home server 50, the controller 280 of the augmented remote controller 200 may create a content guide image using the received content information and the display 260 may display the content guide image in operation S1160.
That is, the personalized information related to the image display apparatus 100 in the power-off state may be information regarding the content played back in the image display apparatus 100. For example, the content information may be information regarding a preferred channel in the image display apparatus 100 or information regarding a history of contents played back in the image display apparatus 100.
The augmented remote controller 200 may display the detected information on the display 260. Accordingly, the user may identify the personalized information related to the image display apparatus 100 without turning it on, even if the image display apparatus 100 is off.
As shown in
Identifying a main image may mean identifying a content being played back at a moment that the image display apparatus 100 is identified. The content may be a multimedia content including a video or both a video and an audio. The augmented remote controller 200 may generate a preview image simultaneously with capturing the image display apparatus 100 that is displaying a main image by playing back a content, or storing the image of the image display apparatus 100, during identifying the image display apparatus 100 and the main image.
The image display apparatus 100 may be identified in various manners. The augmented remote controller 200 may receive metadata related to the main image from the image display apparatus 100. The augmented remote controller 200 may also identify or determine the main image by receiving metadata related to the content corresponding to the main image or metadata related to the user interface image from a broadcasting station that transmits the content or the user interface image, and/or from the network server 300.
The augmented remote controller 200 may receive, in operation S1220, additional information regarding the main image that has been identified together with the image display apparatus 100, through the wireless communication module 210. The additional information regarding the main image may be received from the image display apparatus 100, the broadcasting station that transmits the content corresponding to the main image, the network server 300, and/or the home server 50. To receive the additional information, the augmented remote controller 200 may transmit a signal requesting the additional information regarding the content to the image display apparatus 100, the network server 300, the broadcasting station, etc.
The additional information may specify at least one of the sound features, aspect ratio, image quality, genre, title, synopsis, characters, and play time of the content. The additional information may also provide a channel list that lists channels on a time zone basis, on which multimedia contents are transmitted often to the image display apparatus 100. The additional information may further provide a list of channels that are often transmitted in a current time zone or a list of preferred channels in the current time zone.
Upon receipt of the additional information regarding the content, the augmented remote controller 200 may display, in operation S1230, a content guide image including the additional information. The content guide image may be displayed together with the main image on the display 260.
When the augmented remote controller 200 identifies the image display apparatus 100 that is displaying an image based on a video signal received from a broadcasting station, the augmented remote controller 200 may identify a user and display an EPG or a channel browser for the identified user on the display 260. The EPG or channel browser for the user may be information personalized for the user.
That is, the augmented remote controller 200, which has identified a content based on a broadcast signal as an object, may identify a user, and display an EPG or channel browser for the user authenticated by user authentication. The EPG or channel browser for the user may be an EPG configured to display user-preferred information or a channel browser with information about user-preferred channels.
As shown in
The content guide image may function as a user interface image. Accordingly, the user may input a specific signal such as a user command according to what is displayed or indicated in the content guide image so as to control the augmented remote controller 200 and/or the image display apparatus 100.
The user may enter a user signal according to the content guide image. Thus, the augmented remote controller 200 may receive the user signal through the user interface 230 in operation S1340. The augmented remote controller 200 may generate a remote control signal according to the user signal and transmit the remote control signal to the image display apparatus 100 in operation S1350.
If the content guide image provides a channel list or an EPG, upon input of a user signal to select a channel or a program, the controller 280 of the augmented remote controller 200 may generate a remote control signal based on the user signal and transmit the remote control signal to the image display apparatus 100. The image display apparatus 100 may change a channel or select a program based on the remote control signal.
As shown in
The image display apparatus 100 may be playing a specific content and thus a main image 1400 may be displayed on the display 180. As the augmented remote controller 200 identifies the image display apparatus 100, the augmented remote controller 200 may display an image 1405 of the image display apparatus 100 and the channel list image 1410 as the content guide image on the display 260.
The channel list image 1410 may be a user interface image that provides a list of a channels transmitting the current content, channels adjacent to the current channel, and/or similar channels. The channel that is broadcasting the current content may be indicated by an indication ‘current channel’ in the channel list image 1410.
In the example where a user authentication is performed along with identification of the image display apparatus 100, the channel list image 1410 may provide channel list information edited based on personalized information for the authenticated user. For example, in presence of different preferred channel information registered for different users, when one of the users is authenticated, the augmented remote controller 200 may display a list of preferred channels registered by the user as content information. If different content information is stored for users and a locking function is set, the authenticated user may prevent other users from viewing information registered by the user.
As shown in
It is assumed that the image display apparatus 100 is playing a specific content and the content is a broadcast program received from a broadcasting station. In this example, a broadcast image is displayed as the main image 1400 on the display 180. As the augmented remote controller 200 identifies or determines the image display apparatus 100, the display 260 of the augmented remote controller 200 may display the image 1405 of the image display apparatus 100 and the EPG image 1510 as the content guide image.
The EPG image 1510 may be a program guide image including information regarding the broadcast program corresponding to the broadcast content displayed as the current main image 1400.
To provide personalized EPG information to a user, the user may be authenticated in advance. The user authentication is a process of determining whether the user has been registered or identifying the user from among registered users. Thus only an authorized user can receive content information based on the personalized information. The user may use a content guide image mainly with information edited to increase the user's convenience through the user authentication.
The authenticated user may receive an EPG image that has been edited according to the personalized information. That is, the augmented remote controller 200 may create an EPG image based on the personalized information for the user. For example, when the user registers a time zone or a preferred channel whose information is to be included in an EPG image, the augmented remote controller 200 may search for and collect content information based on the registered time zone or preferred channel and thus generate an EPG image using the collected content information. A broadcast program corresponding to a current content being broadcast may be indicated by an indication ‘current program’ in the EPG image 1510.
As shown in
The augmented remote controller 200 may display, on the display S260, the image 1405 of the image display apparatus 100 that is displaying the main image 1400 as the content is played. Along with the image 1405, the augmented remote controller 200 may also display a user interface image 1610 to allow the user to select information to be received. The user interface image 1610 may include two or more available menu items, and more specifically ‘view channel information’, ‘view program information’, and ‘view additional information’. In the example of
If the current content is a broadcast program received from the broadcasting station, the augmented remote controller 200 may receive metadata related to the content directly from the broadcasting station or through the image display apparatus 100. To display additional content information, the augmented remote controller 200 may use the metadata related to the content in searching for content information.
The additional information displayed as the content information may be information regarding what the content is about, such as title (or name), genre, cast, etc. of the content, and/or information regarding attributes of the content such as an aspect ratio, sound setting information, etc. The augmented remote controller 200 may receive this information from the image display apparatus 100 or the broadcasting station. The augmented remote controller 200 may also acquire this information by searching for related information in a Web page in the network server 300. In this example, the augmented remote controller 200 may display more detailed additional content information based on the metadata related to the content or already obtained partial content information.
As shown in
As shown in
A main image 1700 displayed on the image display apparatus 100 may result from playing a content. The main image 1700 may also be a user interface image provided to the user by the image display apparatus 100. The user interface image displayed as a main image may be a channel list image representing a list of channels available in the image display apparatus 100 or the EPG image 1700 that specifies TV programs received at the image display apparatus 100. With reference to
Referring to
As shown in
For example, the additional EPG information may be user channel information regarding channels pre-registered by the user, channel category information indicating a user-preset channel category, and/or information regarding adjacent channels to a channel on which a main image is received. The user channel information may provide a list of channels registered according to tastes or needs of the user. For example, the user channel information may be information regarding a list of channels listed according to preferences of the user or information regarding channels that the user mainly enjoys at each time zone. The channel category information may indicate a genre of a broadcast program received on a channel or a genre of broadcast programs that the user mainly enjoys from among broadcast programs received on the channel.
Information regarding channels before and after a channel that transmits a broadcast program displayed as a main image may be provided as additional EPG information. Further, information regarding time zones in which the authenticated or identified user mainly use the image display apparatus 100 and information regarding channels that the user mainly views in the time zones may be displayed as additional EPG information on the display 260.
As the image 1405 of the image display apparatus 100 displaying the EPG image 1700 is displayed on the display 260, when the user selects a program or channel on the display 260, additional EPG information regarding the selected program or channel may be provided. Information indicating that the program or channel is a preferred program or channel pre-registered by the user and information regarding other programs or channels in a similar category to the program or channel are provided as the additional EPG information.
Additional EPG information may provide various pieces of information and take various forms. Meanwhile, in
The user may input a user signal through the user interface 230 of the augmented remote controller 200 in order to view the thumbnail image 1720 or other additional information. If the augmented remote controller 200 is equipped with a touch screen function, the user signal may be input through the display 260.
As is apparent from the above description, an image display apparatus or an external device connected to the image display apparatus may be controlled by use of a single remote controller. Additionally, a user can efficiently use and manage contents played or stored in the image display apparatus or the external device connected to the image display apparatus, and information related to the contents.
Detailed information may be provided in addition to a user interface or content information provided through the image display apparatus. Personalized information may be provided to a user after user identification or authentication and security of the personalized information can be maintained.
A method for operating the augmented remote controller may be implemented as code that can be written on a computer-readable recording medium and may thus be read by a processor. The computer-readable recording medium may be any type of recording device in which data is stored in a computer-readable manner. Examples of the computer-readable recording medium may include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disc, an optical data storage, and a carrier wave (e.g., data transmission through the internet). The computer-readable recording medium may be distributed over a plurality of computer systems connected to a network so that computer-readable code is written thereto and executed therefrom in a decentralized manner. Functional programs, code, and code segments needed for realizing embodiments herein may be construed by one of ordinary skill in the art.
