2. Description of the Related Art
With the advancement of digital display technology, it has become possible to connect various external electronic devices that provide video content, such as a set-top box, a digital versatile disc (DVD) player, an audio, and the like, to a display apparatus such as a television.
Accordingly, multiple external electronic devices that serve as image sources may be connected to the display apparatus, and a user may switch among the numerous connected devices.
However, a related art display apparatus may not be able to recognize the exact type or manufacturer of the image source and may simply indicate the source names corresponding to the external electronic devices by the input ports through which the image sources are connected, such as High-Definition Multimedia Interface (HDMI) 1, HDMI 2, video graphics array (VGA), composite, etc. Thus, the user may have difficulty identifying which electronic device corresponds which port. For example, if the user wants to select the set-top box, the user needs to know whether the set-top box is connected to HDMI 1 or HDMI 2.
Accordingly, there exists a need to provide to the user more comprehensive and intuitive information about the external electronic devices connected to the display apparatus.

The remote control 300 may be implemented as various kinds of apparatuses that may transmit control signals for controlling other apparatuses. For example, the remote control 300 may be a dedicated remote control that is able to only control a specific apparatus, or be a multi-brand remote (MBR) which is able to control several apparatuses (otherwise known as a universal remote control), and may be a portable device such as a smartphone, a personal digital assistant (PDA), or the like.

As another example, the display apparatus 100 may update an apparatus name of the image providing apparatus 200 in the display apparatus 100 based on the obtained apparatus information of the image providing apparatus 200.
Hereinafter, the display apparatus 100 in the display system 1000 described above will be described in more detail.
As shown in
The communicator 110 is a component for performing wireless or wired communication with a variety of external devices. Specifically, the communicator 110 may include input/output ports for a wired connection with the external device, and various communication chips such as a Wi-Fi chip, a Bluetooth chip, an near-field communication (NFC) chip, a wireless communication chip, and the like for performing wireless communication.
The communicator 110 may communicate with the image providing apparatus 200 to receive the image from the image providing apparatus 200. In addition, the communicator 110 may transmit a control command allowing the remote control 300 to transmit a specific control signal to the remote control 300. According to an aspect of an exemplary embodiment, the communicator 110 may receive the control signal transmitted from the remote control 330 to control the image providing apparatus 200.
The display 120 is a component for displaying various screens according to a control of the processor 130.
The display 120 may be, for example, implemented as a liquid crystal display (LCD), a cathode-ray tube (CRT), a plasma display panel (PDP), an organic light emitting diode (OLED) display, a transparent OLED (TOLED) display, or the like. In addition, the display 120 may also be implemented in a form of a touch screen capable of sensing a touch manipulation of a user.
The display 120 may display the image provided from the image providing apparatus 200. In addition, the display 120 may display various user interface (UI) screens which are prestored.
The processor 130 is a component for controlling an overall operation of the display apparatus 100.
For example, the processor 130 may include a central processing unit (CPU), a random access memory (RAM), a read-only memory (ROM), and a system bus. Here, the ROM is a component in which an instruction set for booting a system is stored, and the CPU copies an operating system (OS) stored in a storage of the display apparatus 100 to the RAM according to an instruction stored in the ROM, and executes the operating system (OS) to thereby boot the system. When the booting is completed, the CPU copies a variety of applications stored in the storage to the RAM, and executes the applications, thereby making it possible to perform a variety of operations. Hereinabove, although the case in which processor 130 includes only one CPU is described, the processor 130 may be implemented by a plurality of CPUs (or digital signal processor (DSP), system on chip (SoC), etc.) at the time of being implemented.
In particular, the processor 130 may acquire the apparatus information of the image providing apparatus 200 in cooperation with the remote control 300. Specifically, in the case in which the remote control 300 is a dedicated remote control (hereinafter, referred to as a first remote control 300′) of the image providing apparatus 200, the apparatus information may be obtained according to exemplary embodiments to be described below.
The first remote control 300′ may transmit the optical control signal through the optical output unit 320. In this case, the optical output unit 320 may include an infrared-light emitting diode (IR-LED), and may generate an IR control signal according to a control of a processor of the first remote control 300′.
First, when the user presses down any key of the first remote control 300′ to transmit a control signal for controlling the image providing apparatus 200 ({circle around (1)}), the display apparatus 100 may receive the control signal through an optical receiving unit 140 ({circle around (2)}). This is referred to as IR sniffing.
In addition, the image providing apparatus 200 may receive the control signal, and transmit the image to the display apparatus 100 according to the received control signal ({circle around (3)}).
The display apparatus may also receive the control signal, and if an image change is sensed with respect to the image provided from the image providing apparatus 200, the received control signal and a current image may be analyzed ({circle around (4)}).
Specifically, the processor 130 may identify the received control signal based on a waveform of the control signal. In addition, the processor 130 may detect a control command corresponding to the control signal through the image analysis in which images before and after the reception of the control signal are compared. This will be described in more detail with reference to
As shown in
The processor 130 of the display apparatus 100 may compare the first image 410 with the second image 420 and determine that the control command corresponding to the control signal is the control command for performing a channel-up. Specifically, the processor 130 may extract a channel number region 41 of the first image 410, extract a channel number region 42 of the second image 420, and recognize channel numbers of the extracted regions through optical character recognition (OCR), to thereby determine that the channel number has changed from the number of 7 to the number of 8 and determine that the control command corresponds to performing the channel-up.
According to an aspect of an exemplary embodiment, the processor 130 may extract characteristics information of the first image 410 and the second image 420, and transmit the extracted characteristics information to an external server capable of recognizing the image based on the characteristics information of the image. In addition, the processor 130 may receive channel information corresponding to the first image 410 and channel information corresponding to the second image 420 to thereby determine that the channel-up is performed. Here, the characteristics information transmitted to the external server may be a water mark or a digital fingerprint, which is identity information of the image.
According to an aspect of an exemplary embodiment, the processor 130 may compare the images before receiving the control signal and after receiving the control signal, and may determine that the control command corresponding to the control signal is a command for volume control when it is recognized that a graphical object or a volume control on-screen display (OSD) element indicating that a volume is changed appears in the image after receiving the control signal.
Using various known image analysis technologies in addition to the methods described above, the processor 130 may determine which control command corresponds to the received control signal.
In addition, the processor 130 may obtain the apparatus information of the image providing apparatus 200 based on the determined control command and the received control signal. Specifically, the display apparatus 100 may store a plurality of control code sets corresponding to the image providing apparatuses of known manufacturers, and the processor 130 may detect a matching control code set for the received control signal and the determined control command among the plurality of preloaded control code sets to thereby obtain the apparatus information of the image providing apparatus 200. Meanwhile, although the control code sets of the respective manufacturers may be preloaded in the display apparatus 100 is described, the display apparatus 100 may also receive the control code sets of the respective manufacturers from an external server, if needed.
Meanwhile, even for devices designed by different manufacturers, the control signals corresponding to a specific control command may be identical to each other. For example, if a control signal for a channel-up operation in a control code set of manufacturer A and a control signal for a channel-up operation in a control code set of manufacturer B are identical to each other, it may be difficult for the display apparatus 100 to correctly identify the manufacturer of the image providing apparatus 200 by information obtained through the control signal analysis and the image change analysis alone.
Therefore, according to an aspect of an exemplary embodiment, if the image provided from the image providing apparatus 200 includes content capable of specifying the image providing apparatus 200, the apparatus information of the image providing apparatus 200 may be obtained through the image analysis.
For example, the processor 130 may sense a manufacturer's logo of the image providing apparatus 200 from the image provided by the image providing apparatus 200, and may obtain the apparatus information of the image providing apparatus 200 based on the sensed manufacturer logo. However, the method based on the logo recognition is merely one example, and any image may be used as long as the image includes the contents from which the apparatus information of the image providing apparatus 200 may be recognized through the image analysis.
As one example, obtaining the apparatus information through the logo will be described below in more detail with reference to
As shown in
As another example, the processor 130 may sense the channel number and the broadcast logo within the image provided by the image providing apparatus 200 to thereby obtain the apparatus information of the image providing apparatus 200.
Specifically, if the image providing apparatus 200 is a set-top box, even though the channel number is identical for each of the manufacturer of the set-top box, images of different broadcasting stations are provided. For example, it is assumed that a channel 1 in the set-top box of a company A corresponds to CBS, and a channel 1 in the set-top box of a company B corresponds to NBC. The processor 130 may analyze the image provided from the image providing apparatus 200 to determine that the image providing apparatus 200 is the set-top box of the company A when the channel number is 1 and the sensed broadcast logo is CBS, and to determine that the image providing apparatus 200 is the set-top box of the company B when the channel number is 1 and the sensed broadcast logo is NBC. This will be described in more detail with reference to
As shown in
That is, as such, after the processor 130 receives the control signal for controlling the image providing apparatus 200 from the first remote control 300′, when the image is provided from the image providing apparatus 200 and a change is sensed in a current image, the processor may obtain the apparatus information of the image providing apparatus 200 by analyzing the changed image.
Meanwhile, if the image analysis technology as described above returns more than one matching results, recognition accuracy of the logo or the channel number may decrease, and it may be difficult to pinpoint any one manufacturer.
Therefore, in this case, if the method for analyzing the control signal and the image change, and the method for analyzing the contents indicating the manufacturer within the image are simultaneously used, the apparatus information of the image providing apparatus 200 may be more accurately obtained. That is, the processor 130 may receive the control signal transmitted from the first remote control 300′, determine the control command corresponding to the control signal through the image changed to correspond to the control signal, and sense a specific object such as the logo or the channel number within the image provided from the image providing apparatus 200, to thereby finally obtain the apparatus information of the image providing apparatus 200.
As such, the display apparatus 100 may autonomously obtain the apparatus information of the image providing apparatus 200. Alternatively, the display apparatus 100 may obtain the apparatus information of the image providing apparatus 200 by means of the server. Specifically, the processor 130 of the display apparatus 100 may transmit the determined control command and control signal to the server to thereby control the communicator 110 to receive the apparatus information of the image providing apparatus 200 from the server. In addition, the display apparatus 100 may receive data required to analyze the image, for example, information on the logo of the manufacturer, or the like, from the server.
Meanwhile, the data for obtaining the apparatus information of the image providing apparatus 200 through the image analysis, for example, the logo for each of the manufacturers, or the like, may be stored in the display apparatus 100, or may be stored in the external server. In the case in which the data is stored in the external server, the display apparatus 100 may transmit the image provided from the image providing apparatus 200 to the external server to thereby obtain the apparatus information of the image providing apparatus 200 from the external server, or receive the data from the external server, if needed. Meanwhile, if the display apparatus 100 fails to obtain the apparatus information, the display apparatus 100 may transmit the failure result to the external server to thereby receive additional data from the external server and update the data of the display apparatus 100, and the external server may perform a supplementary task so that an accurate image recognition may be performed, based on the failure result.
Meanwhile, the processing for obtaining the apparatus information of the image providing apparatus 200 as described above may be initiated on condition that the image providing apparatus 200 is newly discovered and the control signal for controlling the image providing apparatus 200 is received. Therefore, because the processing for obtaining the apparatus information is performed only when the control signal is received, a waste of a memory may be reduced. Meanwhile, newly discovering the image providing apparatus 200 may mean that a new image providing apparatus 200 is sensed by the display apparatus 100, and may specifically mean that the new image providing apparatus 200 is connected to an input port of the display apparatus 100.
As described above, if the display apparatus 100 obtains the apparatus information of the image providing apparatus 200 in cooperation with the first remote control 300′, it is possible to control the image providing apparatus 200 using another remote control (hereinafter, referred to as a second remote control) instead of the dedicated remote control of the image providing apparatus 200.
Specifically, the display apparatus 100 may control the communicator 110 so as to transmit the control code set corresponding to the obtained apparatus information to the second remote control. In this example, the second remote control is an apparatus that may perform wireless communication such as Bluetooth, and the display apparatus 100 may transmit the control code set via a wireless communication scheme such as Bluetooth through the communicator 110. In addition, the second remote control may control the image providing apparatus 200 using the received control code set.
According to an aspect of an exemplary embodiment, the display apparatus 100 may store information regarding a correspondence relationship between a button of the first remote control and the control code for controlling the image providing apparatus 200. Therefore, a first control signal generated from the second remote control may be converted into a second control signal that is suitable for the control of the image providing apparatus 200. Specifically, if the user selects a specific button in the second remote control, the second remote control transmits the first control signal corresponding to the selected button. The display apparatus 100 receives the first control signal, and transmits a command transmitting the first received control signal and the second control signal corresponding to the apparatus information of the image providing apparatus 200 to the second remote control. In addition, the second remote control may control the image providing apparatus 200 by transmitting the second control signal according to the command received from the display apparatus 100.
In this scheme, the second remote control may be operated as a multi-brand remote (i.e., universal remote control) capable of controlling various image providing apparatuses. In particular, if the second remote control is a remote control capable of controlling the display apparatus 100, it may be more convenient for the user because the user may control the image providing apparatus 200 as well as the display apparatus 100 using only the second remote control instead of having to use multiple remote controls.
Meanwhile, when the apparatus information of the image providing apparatus 200 is obtained, the display apparatus 100 may display a UI screen informing the user that the second remote control may be used instead of the first remote control 300′. This will be described below with reference to
A shown in
Alternatively, the notification UI 715 may also be provided to have a relatively small size within the screen so as not to disturb a viewing of the current image 710, and may be set so that the notification UI 715 automatically disappears after a predetermined time lapses.
According to an aspect of an exemplary embodiment, the display apparatus 100 may transmit the control command for generating the screen such as the notification UI 715 to the second remote control via the wireless communication scheme such as Bluetooth. Accordingly, the screen such as the notification UI 715 may be displayed on a display included in the second remote control. Therefore, the user may be provided with the notification UI 715 from the second remote control without covering the screen of the display apparatus 100.
Alternatively, the display apparatus 100 may transmit a control command outputting a voice informing that the second remote control may control the image providing apparatus 200 to the second remote control. Accordingly, such information may also be output as the voice through a speaker included in the second remote control.
According to the exemplary embodiment described above, because the user does not need to manually input the apparatus information of the image providing apparatus 200 to the display apparatus 100 as in the related art in order to use the second remote control as the multi-brand remote, and it is possible to appropriately inform the user that the second remote control may be used as the multi-brand remote, utilization of the second remote control as the multi-brand remote may be increased.
Meanwhile, the apparatus information of the image providing apparatus 200 obtained by the display apparatus 100 may be used for a multi-brand remote setting of the second remote control, and may also be utilized for a source name update of the image providing apparatus 200 in the display apparatus 100. This will be described with reference to
Specifically, if the processor 130 obtains the apparatus information of the image providing apparatus 200 as in the exemplary embodiments described above, the processor 130 may update a source name corresponding to the image providing apparatus 200 using the obtained apparatus information of the image providing apparatus 200.
As shown in
In addition, the manufacturer information as well as information on a kind of device may also be provided to the updated source list 820. For example, the update source list 820 may include the manufacturer information and the device type if the image providing apparatus 200 is a set-top box, and may include the device type if the image providing apparatus 200 is Blue-ray player, a digital video recorder (DVR), a home theater system (HTS) apparatus, and may include manufacturer information and a device name in the case in which the image providing apparatus is an over-the-top (OTT) and a game device. The information on the kind of device may be obtained by different schemes depending on the device. For example, the information on the kind of device may be obtained by directly inputting, by the user, the information on the kind of device to the display apparatus 100, or may be obtained by only a connection with the display apparatus 100.
Meanwhile, the apparatus information of the image providing apparatus 200 may be used for the source name update as described above, and may be transmitted to the external server to be collected. Accordingly, the external server may provide a service suitable for the business operator of the image providing apparatus 200 through the display apparatus 100. For example, the external server may provide an EPG corresponding to the business operator of the image providing apparatus 200 to the display apparatus 100. As well, the apparatus information of the image providing apparatus 200 may also be used for a statistic purpose.
In
In addition, the display apparatus 100 may obtain the apparatus information of the image providing apparatus 200, based on an image provided from the image providing apparatus 200 after receiving the control signal, and the received control signal (S920).
According to an aspect of an exemplary embodiment, the display apparatus 100 may compare the image provided from the image providing apparatus 200 before the first remote control 300′ transmits the control signal, and the image provided from the image providing apparatus 200 after the first remote control 300′ transmits the control signal, to thereby sense an image change type, and may obtain the apparatus information of the image providing apparatus 200, based on the sensed image change type and the control signal received by the display apparatus 100 from the first remote control 300′.
However, if multiple apparatus candidates are obtained based on the image change type and the control signal, the display apparatus 100 may narrow the choices down to one apparatus based on the contents from which a manufacture of the image providing apparatus 200 may be recognized (e.g., the logo (see
According to an aspect of an exemplary embodiment, the display apparatus 100 may detect contents from which the manufacturer of the image providing apparatus 200 may be detected in the image provided from the image providing apparatus 200, and may select one apparatus from multiple apparatus candidates based on the image change type and the control signal as additionally described in the case in which multiple apparatus candidates are obtained based on the detected contents.
That is, as a method for obtaining, by the display apparatus 100, the apparatus information of the image providing apparatus 200 using the first remote control 300′, (1) a method based on the control signal for which the IR sniffing is performed and the image change is sensed, (2) a method for sensing manufacturer-specific content in the image provided from the image providing apparatus 200, or (3) a method for simultaneously performing the method (1) and the method (2) may be used.
Meanwhile, in the methods (1) and (3), because an information obtaining process may be initiated only if the display apparatus 100 performs sniffing for the IR signal, there is an advantage that memory waste may be reduced.
Overlapping descriptions of the same operations as those described above of the operations of the communicator 110, the display 120, and the processor 130 will be omitted.
The communicator 110 may include an antenna input port 111, HDMI input ports 1 to n (112-1 to 112-n), a USB port 113, a component input jack 114, a PC input jack 115, a button 116, a Bluetooth chip 117, an optical receiver 140, and the like.
The optical receiver 140 may receive an optical signal such as an IR signal through an optical window. The IR signal received through the optical receiver 140 may be a signal for controlling the display apparatus 100, or may be a signal received by performing IR sniffing for a signal for controlling other apparatuses.
The processor 130 may analyze a waveform of the IR signal received with IR sniffing to thereby identify the IR signal. In addition, the processor 130 may analyze the image received through the communicator 110 to thereby sense a change in the image corresponding to the IR signal, and may detect the sensed image change type to thereby determine the control command corresponding to the IR signal. In addition, the processor 130 may obtain the apparatus information corresponding to the determined control command and the IR signal as the apparatus information of the image providing apparatus 200.
The communicator 110 may include a communication chip such as the Bluetooth chip 117. In addition, the communicator 120 may include various communication chips such as a Wi-Fi chip, an NFC chip, a wireless communication chip, and the like. If the Bluetooth chip 117 is used, the communicator 110 may first transmit and receive a variety of access information such as a service set identifier (SSID), a session key, and the like; perform a communication connection using the variety of access information; and then transmit and receive a variety of information.
The display apparatus 100 may include a tuner for selecting a broadcast channel received through the antenna input port 111.
The processor 130 may transmit a variety of control commands to the remote control 300 through the communicator 110 in the Bluetooth communication scheme. In particular, the processor 130 may transmit the control command including the IR code set to the remote control 300 in the Bluetooth scheme.
The button 116 may be, for example, a power button, a mute button, a volume change button, or a channel change button.

The storage 150 may store various data, programs or applications for driving and controlling the display apparatus 100 by the control of the processor 130.
The storage 150 may be a non-volatile memory, a volatile memory, a hard disk drive (HDD), or a solid-state drive (SSD). In addition, the storage 150 may be a memory card (e.g., a micro Secure Digital (SD) card, a USB memory) mounted in the display apparatus 100.
The storage 150 may store various modules such as an image processing module, an image recognition module, an IR sniffing module, and the like.
