Description

Electronic device and method of operation of electronic device

[0001] The present disclosure relates to an electronic device and a method of operating the electronic device. Specifically, it relates to an electronic device that transmits image data processed according to a modulation coding method and a method of operating the electronic device.

[0002] Recently, wireless connection services are being researched that wirelessly connect a source device that shares a screen and a sink device that receives the screen. The source device may be a device that generates or transmits content. The sink device may be a device connected to the source device that receives and outputs content from the source device.

[0003] A source device can receive and process various input signals and transmit content to a display device, which is an example of a sink device. The input signals may include video, audio, and additional information. The source device can connect external source devices to itself, process the input signals, and transmit them wirelessly to the display device.

[0004] For example, a source device can receive a digital broadcast signal (DTV) or an analog broadcast signal (ATV) from a broadcast network, digitize it, and transmit it to a display device. Alternatively, for example, the source device may be wired to external source devices, receive and process input signals from the external source devices via wires, and transmit them wirelessly to the display device.

[0005] Accordingly, the source device can transmit high-resolution video and audio data to the display device without other wired connections such as HDMI cables or USB. The display device can output the content received from the source device to the display.

[0006] In addition, depending on the communication environment between the source device and the sink device, the source device can determine the level of the modulation coding scheme of the data to be transmitted, and provide the data processed according to the determined level of the modulation coding scheme to the sink device through a channel of a specific frequency band.

[0007] One embodiment of the present disclosure provides an electronic device. The electronic device may include a memory in which a program or at least one instruction is stored. The electronic device may include at least one processor. By having at least one processor execute the program or at least one instruction stored in the memory individually or collectively, the electronic device may obtain a first quality evaluation score corresponding to the transmission quality of image data processed according to a first level Modulation and Coding Scheme (MCS) being transmitted through a first frequency band. The electronic device may obtain a second quality evaluation score corresponding to the transmission quality of image data processed according to a second level Modulation and Coding Scheme being transmitted through a second frequency band different from the first frequency band. The electronic device may compare each of the first quality evaluation score and the second quality evaluation score with a preset reference evaluation score. As the electronic device identifies that at least one of the first quality evaluation score or the second quality evaluation score is lower than the reference evaluation score, it can adjust the level of the modulation coding scheme of at least one frequency band corresponding to the quality evaluation score lower than the reference evaluation score so that it is lower. The electronic device can transmit image data processed according to the modulation coding scheme of the adjusted level of at least one frequency band through at least one frequency band.

[0008] In one embodiment of the present disclosure, a method of operating an electronic device may be provided. The method of operating an electronic device may include the step of obtaining a first quality evaluation score corresponding to the transmission quality of image data processed according to a first level modulation and coding scheme (MCS) being transmitted through a first frequency band. The method of operating an electronic device may include the step of obtaining a second quality evaluation score corresponding to the transmission quality of image data processed according to a second level modulation and coding scheme (MCS) being transmitted through a second frequency band different from the first frequency band. The method of operating an electronic device may include the step of comparing each of the first quality evaluation score and the second quality evaluation score with a preset reference evaluation score. As it is identified that at least one of the first quality evaluation score or the second quality evaluation score is lower than the reference evaluation score, the method of operating an electronic device may include the step of adjusting the level of the modulation and coding scheme of at least one frequency band corresponding to the quality evaluation score lower than the reference evaluation score so that it is lowered. The method of operation of an electronic device may include the step of transmitting image data processed according to a modulation coding method of a controlled level of at least one frequency band through at least one frequency band.

[0009] In one embodiment of the present disclosure, a computer-readable recording medium may be provided on which a program for performing at least one of the embodiments of the method of operating the disclosed electronic device is recorded on a computer.

[0037] Embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0038] FIG. 1 is a drawing for explaining the operation of an electronic device according to one embodiment of the present disclosure.

[0039] Referring to FIG. 1, in one embodiment of the present disclosure, FIG. 1 shows an electronic device (100) and a display device (200).

[0040] In one embodiment of the present disclosure, an electronic device (100) may provide image data (300) to a display device (200). The display device (200) includes a display (210) and may display an image (220) on the display (210) based on the image data (300) received through the electronic device (100).

[0041] In one embodiment of the present disclosure, the electronic device (100) may include a set-top box, a Blu-ray Disc player, a DVD (Digital Versatile Disc) player, a game console, a digital camera, a camcorder, a streaming device, a home theater, etc. In one embodiment of the present disclosure, the electronic device (100) may be referred to as a source device, a transmitting device, or a transmitter (TX).

[0042] However, the present disclosure is not limited thereto, and the electronic device (100) may include a device that performs the operation of receiving various content from an external device and providing it to a display device (200).

[0043] In one embodiment of the present disclosure, content may mean multimedia content and may include, but is not limited to, images, videos, audio, text, games, applications, broadcasts, etc.

[0044] In one embodiment of the present disclosure, an electronic device (100) may receive various content from an external device through an input / output interface or a communication interface. Additionally, in one embodiment of the present disclosure, the electronic device (100) may receive various applications, for example, OTT content provided by an OTT (Over-The-Top) service provider, through an input / output interface or a communication interface.

[0045] In one embodiment of the present disclosure, the electronic device (100) may receive broadcast content from a broadcast network. The broadcast content may be various forms of media composed of a collection of media components (e.g., video, audio, subtitles, service announcements, etc.) provided to a user using the display device (200).

[0046] In one embodiment of the present disclosure, an electronic device (100) can convert acquired content and provide acquired image data (300) to a display device (200).

[0047] In one embodiment of the present disclosure, the display device (200) may include various electronic devices including a display such as a TV, smartphone, tablet PC, mobile terminal, video phone, e-book reader, desktop PC, laptop PC, netbook computer, navigation, wearable device, head-mounted display device, etc.

[0048] However, the present disclosure is not limited thereto, and the display device (200) may include other types of devices capable of performing the operation of providing an image (220) to a user through a display (210) based on image data provided from an electronic device (100). In one embodiment of the present disclosure, the display device (200) may be referred to as a sink device, a receiving device, or a receiver (RX).

[0049] In one embodiment of the present disclosure, an electronic device (100) and a display device (200) may be connected to each other through a wireless communication network. Data communication between the electronic device (100) and the display device (200) may be performed through a communication interface included in the electronic device (100) and a communication interface included in the display device (200).

[0050] In one embodiment of the present disclosure, an electronic device (100) and a display device (200) can perform data communication through a communication method such as Wireless LAN, Wi-Fi, Bluetooth, BLE (Bluetooth Low Energy), Zigbee, WFD (Wi-Fi Direct), NFC (Near Field Communication), WiMAX (World Interoperability for Microwave Access), SWAP (Shared Wireless Access Protocol), WiGig (Wireless Gigabit Alliance), or RF communication.

[0051] Hereinafter, in one embodiment of the present disclosure, an electronic device (100) and a display device (200) are described as performing data communication using a Wi-Fi communication method. A communication interface included in the electronic device (100) and a communication interface included in the display device (200) may each include a Wi-Fi chip capable of performing Wi-Fi communication.

[0052] In one embodiment of the present disclosure, an electronic device (100) and a display device (200) can perform data communication between the electronic device (100) and the display device (200) via a Wi-Fi Direct (WFD) method without passing through an Access Point (AP). However, the present disclosure is not limited thereto, and the electronic device (100) and the display device (200) may also perform data communication via Wi-Fi through an Access Point or router, such as an internet sharing device.

[0053] However, the present disclosure is not limited thereto, and it is obvious that the electronic device (100) and the display device (200) may use various communication methods capable of performing the operation of providing image data (300) from the electronic device (100) to the display device (200) in order to display an image (220) on the display (210).

[0054] In one embodiment of the present disclosure, the electronic device (100) can transmit and receive data with a display device (200) through a specific frequency band (e.g., a 2.4 GigaHerz (GHz) band, a 5 GHz band, or a 6 GHz band) while performing data communication using a Wi-Fi communication method.

[0055] Additionally, the electronic device (100) can transmit and receive data with the display device (200) through a channel included within a specific frequency band.

[0056] In one embodiment of the present disclosure, the electronic device (100) can perform data communication with the display device (200) simultaneously through two different frequency bands.

[0057] In one embodiment of the present disclosure, the electronic device (100) can perform data communication with the display device (200) using a frequency band of 5 GHz and a frequency band of 6 GHz.

[0058] This operation may be referred to as MLO (Multi Link Operation) when the electronic device (100) performs data communication using Wi-Fi 7, but it goes without saying that such a name may vary and is not limited.

[0059] In one embodiment of the present disclosure, as the electronic device (100) provides image data (300) using different frequency bands, the electronic device (100) can provide image data (300) to a display device (200) at a high speed.

[0060] Additionally, the electronic device (100) can provide image data (300) in one of the two frequency bands and obtain control signals or request signals, etc. from the display device (200) in the other frequency band, thereby preventing delay in data communication.

[0061] However, in one embodiment of the present disclosure, if the communication environment of any one of the different frequency bands is not smooth, the transmission of some data of the image data (300) transmitted from the electronic device (100) to the display device (200) through the said frequency band may be delayed or the quality may be lowered.

[0062] Accordingly, when converting acquired content into video data (300), the electronic device (100) can use the Modulation and Coding Scheme (MCS) level by adjusting it according to the communication environment of a specific frequency band.

[0063] At this time, "modulation coding scheme" may represent a combination of a modulation scheme used to transmit data through a wireless communication system, such as QPSK, 16-QAM, 64-QAM, etc., and a coding rate, such as 1 / 2, 3 / 4, 5 / 6, etc. "Level of modulation coding scheme" represents a combination of multiple modulation schemes and multiple coding rates provided by a wireless communication network, and a modulation coding scheme corresponding to each of the multiple levels may be defined.

[0064] In one embodiment of the present disclosure, as the level of the modulation coding scheme increases, a modulation coding scheme combining a higher-order modulation scheme and a high coding speed may be defined to correspond. As the level of the modulation coding scheme decreases, a modulation coding scheme combining a lower-order modulation scheme and a low coding speed may be defined to correspond.

[0065] In one embodiment of the present disclosure, as the level of the modulation coding scheme increases, the data transmission rate increases and high reception sensitivity may be required. In this case, the transmission rate may refer to the transmission speed. As the level of the modulation coding scheme decreases, the transmission rate decreases and low reception sensitivity may be required. Accordingly, as the level of the modulation coding scheme decreases, the error rate of data transmission may decrease.

[0066] Therefore, the better the state of the communication environment in the frequency band, such as the Channel Quality Indicator (CQI), the higher the level of modulation coding used to process and transmit data. Conversely, the less favorable the state of the communication environment in the frequency band, the lower the level of modulation coding used to process and transmit data.

[0067] However, if the electronic device (100) adjusts the level of the modulation coding method according to changes in the communication environment of the frequency band due to interference from external electronic devices, and the data transmission rate changes accordingly, the stability of the electronic device (100) in transmitting video data (300) to the display device (200) is lowered, and the quality of the video (220) provided to the user may also be lowered.

[0068] Additionally, as the electronic device (100) continuously adjusts the level of the modulation coding method and the modulation coding method of the data according to changes in the communication environment, unnecessary power may be consumed.

[0069] Accordingly, in one embodiment of the present disclosure, when transmitting image data (300) to a display device (200) through an electronic device (100) via two different frequency bands, the level of the modulation coding method to be used in each frequency band is adjusted by considering the communication environment of each frequency band, and data communication can be performed using the adjusted level of the modulation coding method.

[0070] In addition, in one embodiment of the present disclosure, the electronic device (100) can fix and use the level of the modulation coding method determined by considering the communication environment of each frequency band as the level of the modulation coding method in the corresponding frequency band, thereby preventing the operation of unnecessarily adjusting the level of the modulation coding method from being performed.

[0071] Additionally, in one embodiment of the present disclosure, the electronic device (100) may perform an operation to increase the level of a modulation coding method in a frequency band with a good communication environment in order to provide image data (300) to the display device (200) at a higher transmission rate than the required transmission rate of image data (300) required for the display device (200) to display the image (220) without interruption, based on the resolution or frequency of the image (220).

[0072] Through this, the electronic device (100) of the present disclosure can stably transmit image data (300) to a display device (200) and enable the display device (200) to provide a high-quality image (220) to a user. In addition, the power consumption required for the electronic device (100) to transmit image data (300) to the display device (200) can be reduced.

[0073] Hereinafter, the operation and configuration of the electronic device (100) will be described in FIGS. 2 to 9.

[0074] FIG. 2 is a block diagram for explaining the configuration of an electronic device according to one embodiment of the present disclosure.

[0075] Referring to FIGS. 1 and FIGS. 2, in one embodiment of the present disclosure, an electronic device (100) may include a memory (110), at least one processor (120), an input / output interface (130), and a communication interface (140).

[0076] However, not all of the components shown in FIG. 2 are essential components. The electronic device (100) may be implemented with more components than those shown in FIG. 2, or with fewer components.

[0077] In one embodiment of the present disclosure, a memory (110), at least one processor (120), an input / output interface (130), and a communication interface (140) may each be electrically connected to one another.

[0078] In one embodiment of the present disclosure, the memory (110) may store instructions, data structures, and program code that can be read by at least one processor (120). In one embodiment of the present disclosure, the memory (110) may be one or more. Operations performed by the electronic device (100) may be implemented by at least one processor (120) executing the instructions or code of a program stored in the memory (110).

[0079] In one embodiment of the present disclosure, the memory (110) may include at least one of a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (e.g., SD or XD memory, etc.), RAM (Random Access Memory), SRAM (Static Random Access Memory), ROM (Read-Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read-Only Memory), Mask ROM, Flash ROM, etc.), a hard disk drive (HDD), or a solid-state drive (SSD).

[0080] In one embodiment of the present disclosure, the memory (110) may not exist separately and may be configured to be included in at least one processor (120).

[0081] In one embodiment of the present disclosure, instructions or program code for performing functions or operations of an electronic device (100) may be stored in the memory (110). The instructions, algorithms, data structures, program code, and application programs stored in the memory (110) may be implemented in a programming or scripting language such as, for example, C, C++, Java, Python, assembler, etc.

[0082] In one embodiment of the present disclosure, various types of modules that can be used to perform the operation of an electronic device (100) may be stored in the memory (110).

[0083] In one embodiment of the present disclosure, the memory (110) may store a transmission quality evaluation module (111), a modulation coding method level adjustment module (112), a data processing module (113), a transmission speed comparison module (114), and a transmission method determination module (115). However, not all modules and configurations included in the memory (110) illustrated in FIG. 2 are required. More modules or configurations than those illustrated in FIG. 2 may be stored in the memory (110), or fewer modules or configurations may be stored.

[0084] In one embodiment of the present disclosure, a 'module' included in the memory (110) may mean a unit that processes a function or operation performed by at least one processor (120). The 'module' included in the memory (110) may be implemented as software such as instructions, algorithms, data structures, or program code.

[0085] In one embodiment of the present disclosure, the transmission quality evaluation module (111) may be composed of instructions or program code regarding an operation or function to evaluate the transmission quality of video data (300) transmitted in a specific frequency band through a communication interface (140).

[0086] In one embodiment of the present disclosure, the transmission quality evaluation module (111) may be composed of instructions or program code regarding an operation or function for evaluating the transmission quality of image data (300) based on at least one of the transmission failure rate of a packet of image data (300) transmitted through a frequency band, the number of packet retransmissions, the lifetime of a packet, or the latency of a packet.

[0087] In this case, "packetization" may refer to the operation of dividing data into small units of packets and adding a header containing information about the data to create a packet form. "Packet" may refer to a unit of image data (300) divided through the packetization operation.

[0088] In one embodiment of the present disclosure, a transmission quality evaluation module (111) can compare an acquired quality evaluation score with a preset reference evaluation score to identify whether the quality evaluation score, which indicates the transmission quality of video data transmitted through a specific frequency band, is lower than the reference evaluation score. At this time, the "reference evaluation score" may be a preset value to determine whether the communication environment of the frequency band is good or not smooth due to interference, etc.

[0089] In one embodiment of the present disclosure, a quality evaluation score may be obtained based on a packet transmission failure rate, which is the ratio of the number of at least one packet that failed to be transmitted to the number of packets of video data (300) transmitted through the corresponding frequency band. The transmission quality evaluation module (111) may be composed of instructions or program code regarding operations or functions that evaluate the quality evaluation score as higher the packet transmission failure rate is lower. In this case, the reference evaluation score may be set to a packet transmission failure rate of 10%.

[0090] In one embodiment of the present disclosure, a quality evaluation score may be obtained based on the number of retransmissions of packets of video data (300) transmitted through the corresponding frequency band. The transmission quality evaluation module (111) may be composed of instructions or program code regarding an operation or function that evaluates the quality evaluation score as higher the number of retransmissions of packets of transmitted video data (300) is lower. In this case, the reference evaluation score may be set to three times the number of retransmissions of packets of transmitted video data (300).

[0091] In one embodiment of the present disclosure, a quality evaluation score may be obtained based on the lifetime of a packet of video data (300) transmitted through the corresponding frequency band. The transmission quality evaluation module (111) may be composed of instructions or program code regarding an operation or function that evaluates the quality evaluation score as higher when the lifetime of the packet of the transmitted video data (300) is shorter. In this case, the reference evaluation score may be set to a lifetime of 1ms for the packet of the transmitted video data (300).

[0092] In one embodiment of the present disclosure, a quality evaluation score may be obtained based on the latency of a packet of video data (300) transmitted through the corresponding frequency band. The transmission quality evaluation module (111) may be composed of instructions or program code regarding an operation or function that evaluates the quality evaluation score as higher the shorter the latency of the packet of the transmitted video data (300). In this case, the reference evaluation score may be set to a latency of 1ms for the packet of the transmitted video data (300).

[0093] However, the present disclosure is not limited thereto, and it is obvious that the reference evaluation score may be set differently depending on the transmission rate or error rate of the data to be maintained when the electronic device (100) provides image data (300) using a wireless communication network.

[0094] In one embodiment of the present disclosure, by having at least one processor (120) execute instructions or program code of a transmission quality evaluation module (111), the electronic device (100) can evaluate the transmission quality of image data (300) transmitted over a specific frequency band. Additionally, the electronic device (100) can compare the acquired quality evaluation score with a preset reference evaluation score to identify whether the quality evaluation score, which indicates the transmission quality of image data transmitted over a specific frequency band, is lower than the reference evaluation score.

[0095] In one embodiment of the present disclosure, the modulation coding method level adjustment module (112) may be composed of commands or program code regarding an operation or function of adjusting the level of a modulation coding method for processing acquired content in order to transmit video data (300) through each channel.

[0096] In one embodiment of the present disclosure, the modulation coding method level adjustment module (112) may be composed of instructions or program code regarding an operation or function of adjusting the level of the modulation coding method to be lowered or to be raised.

[0097] By having at least one processor (120) execute instructions or program code of the modulation coding method level adjustment module (112), the electronic device (100) can adjust the level of the modulation coding method for processing acquired content to transmit video data (300) through each channel. Additionally, the electronic device (100) can adjust the level of the modulation coding method to be lowered or to be raised.

[0133] In step S120, the electronic device (100) can use the transmission quality evaluation module (111) to obtain a second quality evaluation score corresponding to the transmission quality of image data processed according to a second level modulation coding method and transmitted through a second frequency band.

[0134] In one embodiment of the present disclosure, the first frequency band may be a 5 GHz (GigaHertz) band. Specifically, the first frequency band may include a range of 5.180 to 5.850 GHz. The second frequency band may be a 6 GHz band. Specifically, the second frequency band may include a range of 5.925 GHz to 7.125 GHz.

[0135] However, the present disclosure is not limited thereto, and it is understood that either of the first frequency band and the second frequency band may have a 2.4 GHz band, and the other frequency band may have a 5 GHz or 6 GHz band. Furthermore, the first frequency band may mean a 6 GHz band and the second frequency band may mean a 5 GHz band. Hereinafter, the first frequency band will be described as a 5 GHz band and the second frequency band as a 6 GHz band.

[0136] In one embodiment of the present disclosure, a plurality of channels may be included in the first frequency band and the second frequency band, respectively. Each channel may have a width of tens to hundreds of MHz (MegaHertz), and the number of channels included in the first frequency band and the second frequency band may vary depending on the width of the channel.

[0137] In one embodiment of the present disclosure, image data transmitted through a first frequency band may include being transmitted through any one of a plurality of channels included within the first frequency band. Image data transmitted through a second frequency band may include being transmitted through any one of a plurality of channels included within the second frequency band.

[0138] In one embodiment of the present disclosure, the operation of step S110 and the operation of step S120 may be performed in a single step (S100) of obtaining a channel quality evaluation score. The electronic device (100) may obtain a first quality evaluation score in a first frequency band and a second quality evaluation score in a second frequency band in step S100.

[0139] In one embodiment of the present disclosure, a method of operating an electronic device (100) may include a step (S200) of comparing each of a first quality evaluation score and a second quality evaluation score with a preset reference evaluation score. Step S200 may include a step of identifying whether each of the first quality evaluation score and the second quality evaluation score is lower than the preset reference evaluation score.

[0140] In step S200, the electronic device (100) can use the transmission quality evaluation module (111) to compare the first quality evaluation score and the second quality evaluation score, respectively, with a preset reference evaluation score. The electronic device (100) can use the transmission quality evaluation module (111) to identify whether the first quality evaluation score and the second quality evaluation score, respectively, are lower than the preset reference evaluation score.

[0141] In one embodiment of the present disclosure, the method of operation of an electronic device (100) may include a step (S300) of adjusting the level of a modulation coding scheme of at least one frequency band corresponding to a quality evaluation score lower than the reference evaluation score so that it is lowered, as it is identified that at least one of a first quality evaluation score or a second quality evaluation score is lower than the reference evaluation score.

[0142] In step S300, the electronic device (100) can use a modulation coding method level adjustment module (112) to adjust the level of the modulation coding method of at least one frequency band corresponding to a quality evaluation score lower than the reference evaluation score so that it is lower.

[0145] In step S400, the electronic device (100) can transmit video content to the display device (200) through the communication interface (140) via the first frequency band and the second frequency band, respectively.

[0146] The detailed operation of steps S200, S300, and S400 below will be described later in FIG. 5.

[0147] FIG. 4 is a diagram illustrating a method of transmitting image data to a display device using an electronic device according to one embodiment of the present disclosure.

[0148] Referring to FIGS. 1, FIGS. 2 and FIGS. 4, in one embodiment of the present disclosure, FIG. 4 illustrates a first case (400), a second case (430) and a third case (440) in which an electronic device (100) provides image data (300) to a display device (200) in different ways through a wireless communication network.

[0149] In one embodiment of the present disclosure, the first case (400) may be a diagram showing a case in which an electronic device (100) operates to provide image data (300) to a display device (200) through two channels (411, 421) included in different frequency bands (410, 420).

[0150] In one embodiment of the present disclosure, the first frequency band (410) may mean a 5 GHz frequency band. The second frequency band (420) may mean a 6 GHz frequency band. The first channel (411) may mean any one of a plurality of channels included within the first frequency band (410). The second channel (421) may mean any one of a plurality of channels included within the second frequency band (420).

[0151] In one embodiment of the present disclosure, in the first case (400), the electronic device (100) can provide the first image data and the second image data to the display device (200) through the first channel (411) and the second channel (421), respectively, which are included in different frequency bands.

[0152] At this time, the first image data may be processed according to a modulation coding method of a level adjusted considering the communication environment of the first channel (411). The second image data may be processed according to a modulation coding method of a level adjusted considering the communication environment of the second channel (421).

[0153] In one embodiment of the present disclosure, the sum of the first image data and the second image data may be the same as the image data that the electronic device (100) intends to provide to the display device (200) by converting the acquired content. The display device (200) may display an image (220) based on the first image data and the second image data.

[0154] Additionally, the electronic device (100) may transmit video data to either the first channel (411) or the second channel (421), and receive a control signal or a request signal from the display device (200) to the other channel.

[0155] In one embodiment of the present disclosure, as the sum of the transmission speed of the first image data and the transmission speed of the second image data is equal to or greater than the required data transmission speed required for the display device (200) to display the image (220), the electronic device (100) can operate in the manner of the first case (400) to transmit image data to the display device (200).

[0156] In one embodiment of the present disclosure, when the electronic device (100) and the display device (200) perform data communication using Wi-Fi 7, the first case (400) may be a case where image data is transmitted using the MLO method.

[0157] In one embodiment of the present disclosure, the second case (430) may be a diagram illustrating a case in which an electronic device (100) operates to provide image data (300) to a display device (200) through channels (412, 413) included in a first frequency band (410) in a multi-input multi-output manner.

[0158] In one embodiment of the present disclosure, the second case (430) is illustrated as transmitting image data (300) through two channels (412, 413) included in the first frequency band (410), but the present disclosure is not limited thereto. In the second case (430), the width of the channels included in the first frequency band (410) may be wider than the width of the channels in the first case (400). Additionally, in the second case (430), the first channel (411) may also be used, and data communication may be performed in a multiple-input multiple-output manner through the first channel (411) using spatial multiplexing.

[0159] In one embodiment of the present disclosure, the image data (300) in the second case (430) may be processed according to a modulation coding method of a level adjusted considering the communication environment of the channels (412, 413) included in the first frequency band (410). The image data (300) in the second case (430) may be processed according to a modulation coding method of the same level.

[0160] In one embodiment of the present disclosure, the electronic device (100) can transmit video data (300) processed by a modulation coding method of a level adjusted to be lowered in consideration of the communication environment of the second channel (421) when the communication environment of the second channel (421) is poor. In this case, as the video data (300) is provided to the display device (200) at a transmission speed lower than the required data transmission speed required by the display device (200), the quality of the image (220) displayed by the display device (200) may be lowered.

[0161] Accordingly, the electronic device (100) can transmit image data (300) to the display device (200) by utilizing the frequency band of the first channel (411) where the communication environment is determined to be good, in a multi-input multi-output manner.

[0162] In one embodiment of the present disclosure, the third case (440) may be a diagram illustrating a case in which an electronic device (100) operates to provide image data (300) to a display device (200) through channels (422, 423) included in a second frequency band (420) in a multi-input multi-output manner.

[0163] In one embodiment of the present disclosure, the third case (440) is illustrated as transmitting image data (300) through two channels (422, 423) included in the second frequency band (420), but the present disclosure is not limited thereto. In the third case (440), the width of the channels included in the second frequency band (420) may be wider than the width of the channels in the first case (400). Additionally, in the third case (440), the second channel (421) may also be used, and data communication may be performed in a multiple-input multiple-output manner through the second channel (421) using spatial multiplexing.

[0164] In one embodiment of the present disclosure, the image data (300) in the third case (440) may be processed according to a modulation coding method of a level adjusted considering the communication environment of the channels (422, 423) included in the second frequency band (420). The image data (300) in the third case (440) may be processed according to a modulation coding method of the same level.

[0165] In one embodiment of the present disclosure, the electronic device (100) can transmit video data (300) processed by a modulation coding method of a level adjusted to be lowered in consideration of the communication environment of the first channel (411) when the communication environment of the first channel (411) is poor. In this case, as the video data (300) is provided to the display device (200) at a transmission speed lower than the required data transmission speed required by the display device (200), the quality of the image (220) displayed by the display device (200) may be lowered.

[0166] Accordingly, the electronic device (100) can transmit image data (300) to the display device (200) by utilizing the frequency band of the second channel (421) where the communication environment is determined to be good, operating in a multi-input multi-output manner.

[0167] FIG. 5 is a flowchart illustrating an operation to adjust the level of a modulation coding method of image data transmitted through a first frequency band and a second channel frequency band according to an embodiment of the present disclosure.

[0170] In one embodiment of the present disclosure, an electronic device (100) may obtain a first quality evaluation score based on at least one of the transmission failure rate of a packet of image data that is processed by a first level modulation coding method and transmitted through a first frequency band, the number of packet retransmissions, the lifetime of the packet, or the delay time of the packet. The electronic device (100) may identify whether the first quality evaluation score is lower than the reference evaluation score by comparing the reference evaluation score set according to each evaluation criterion with the first quality evaluation score.

[0171] In one embodiment of the present disclosure, step (S200) may include step (S220) of identifying whether the second quality evaluation score is lower than a preset reference evaluation score.

[0172] In step S220, the electronic device (100) can use the transmission quality evaluation module (111) to compare the second quality evaluation score with the reference evaluation score and identify whether the second quality evaluation score is lower than the reference evaluation score.

The electronic device (100) may identify whether the second quality evaluation score is lower than the reference evaluation score by comparing the reference evaluation score set according to each evaluation criterion with the second quality evaluation score.

[0174] In one embodiment of the present disclosure, as it is identified in step S210 that the first quality evaluation score is lower than the reference evaluation score, the method of operation of the electronic device (100) may include a step (S310) of adjusting the level of the modulation coding scheme of the first frequency band to be lowered.

[0175] In step S310, the electronic device (100) can use the modulation coding scheme level determination module (112) to adjust the level of the modulation coding scheme of the first frequency band to be lowered as it is identified that the first quality evaluation score is lower than the reference evaluation score.

[0176] In one embodiment of the present disclosure, the method of operation of the electronic device (100) may further include the step of comparing a first quality evaluation score and a reference evaluation score of image data that is processed and transmitted using a modulation coding method of a level adjusted in a first frequency band.

In one embodiment of the present disclosure, the operations of step S210 and step S310 may be repeated until it is identified that the first quality evaluation score is equal to or higher than the reference evaluation score.

[0178] At this time, the first quality evaluation score of the image data processed and transmitted using a modulated level coding method may also be referred to as the corrected quality evaluation score.

[0179] In one embodiment of the present disclosure, as it is identified in step S210 that the first quality evaluation score is equal to or higher than the reference evaluation score, the method of operation of the electronic device (100) may include the step (S320) of maintaining the level of the modulation coding scheme of the first frequency band.

[0180] In step S320, the electronic device (100) can maintain the level of the modulation coding scheme of the first frequency band without correction.

[0181] In one embodiment of the present disclosure, as the first quality evaluation score obtained in step S110 is identified as being equal to or higher than the reference evaluation score in step S210, the level of the modulation coding scheme of the first frequency band may be maintained at the first level in step S320.

[0182] However, the present disclosure is not limited thereto, and after the level of the modulation coding method of the first frequency band is adjusted to be lowered through step S310, if the first quality evaluation score is identified as being equal to or higher than the reference evaluation score in step S210, the level of the modulation coding method of the first frequency band may be maintained at the adjusted level in step S320.

[0183] In one embodiment of the present disclosure, as it is identified in step S220 that the second quality evaluation score is lower than the reference evaluation score, the method of operation of the electronic device (100) may include a step (S330) of adjusting the level of the modulation coding scheme of the second frequency band to be lowered.

[0184] In step S330, the electronic device (100) can use the modulation coding scheme level determination module (112) to adjust the level of the modulation coding scheme of the second frequency band to be lowered as it is identified that the second quality evaluation score is lower than the reference evaluation score.

[0185] In one embodiment of the present disclosure, the method of operation of the electronic device (100) may further include the step of comparing a second quality evaluation score and a reference evaluation score of image data that is processed and transmitted using a modulation coding method of a level adjusted in a second frequency band.

[0186] In one embodiment of the present disclosure, as it is identified that the second quality evaluation score is lower than the reference evaluation score, the method of operation of the electronic device (100) may perform the operation of step S330 again. In one embodiment of the present disclosure, the operations of step S220 and step S330 may be repeated until it is identified that the second quality evaluation score is equal to or higher than the reference evaluation score.

[0187] At this time, the second quality evaluation score of the image data transmitted after being processed by a modulated level coding method may also be referred to as the correction quality evaluation score.

[0189] In step S340, the electronic device (100) can maintain the level of the modulation coding scheme of the second frequency band without correction.

[0190] In one embodiment of the present disclosure, as it is identified in step S220 that the second quality evaluation score obtained in step S120 is equal to or higher than the reference evaluation score, the level of the modulation coding method of the second frequency band may be maintained at the second level in step S340. However, the present disclosure is not limited thereto, and after the level of the modulation coding method of the second channel is adjusted to be lowered through step S330, as it is identified in step S220 that the second quality evaluation score is equal to or higher than the reference evaluation score, the level of the modulation coding method of the second channel may be maintained at the adjusted level in step S340.

[0191] In one embodiment of the present disclosure, the method of operation of an electronic device (100) may include the step (S400) of transmitting image data processed according to a modulation coding method of a controlled level through a first frequency band and a second frequency band, respectively.

[0192] In step S400, the electronic device (100) can transmit image data processed according to a modulation coding method of a controlled level through the communication interface (140) to each of the first frequency band and the second frequency band.

[0193] In one embodiment of the present disclosure, step S400 may include a step (S410) of transmitting first image data processed according to a modulation coding method of a level adjusted through a first frequency band.

[0194] In step S410, the electronic device (100) can transmit first image data processed according to a level modulation coding method adjusted to a first frequency band through the communication interface (140) to the display device (200).

[0195] The level of the modulation coding method determined in step S410 may refer to a correction level adjusted to a level lower than the first level in step S110 via step S310 according to the identification result of step S210. Additionally, the level of the modulation coding method determined in step S410 may refer to a level determined to maintain the first level in step S110 via step S320 according to the identification result of step S210.

[0196] Accordingly, the electronic device (100) can transmit first image data processed according to the level of a modulation coding method adjusted to have a first quality evaluation score equal to or higher than a reference evaluation score through a first frequency band.

[0197] In one embodiment of the present disclosure, step S400 may include a step (S420) of transmitting second image data processed according to a modulation coding method of a level adjusted through a second frequency band.

[0198] In step S420, the electronic device (100) can transmit second image data processed according to a modulation coding method of a level adjusted to a second frequency band through the communication interface (140) to the display device (200).

[0199] The level of the adjusted modulation coding scheme in step S420 may refer to a correction level adjusted to a level lower than the second level in step S120 via step S330 according to the identification result of step S220. Additionally, the level of the determined modulation coding scheme in step S420 may refer to a level determined to maintain the second level in step S120 via step S340 according to the identification result of step S220.

[0200] Accordingly, the electronic device (100) can transmit second image data processed according to the level of a modulation coding method adjusted to have a second quality evaluation score equal to or higher than a reference evaluation score through a second frequency band.

[0201] FIG. 6 is a flowchart illustrating a method of operation for an electronic device that operates such that the sum of the data transmission speed through a first frequency band and the data transmission speed through a second frequency band is greater than the required data transmission speed, according to one embodiment of the present disclosure. Hereinafter, the same reference numerals are assigned to steps identical to those described in FIG. 3 and FIG. 5, and redundant descriptions are omitted.

[0202] In one embodiment of the present disclosure, FIG. 6 may be an example in which, in step S210, the first quality evaluation score of the first frequency band is identified as lower than the reference evaluation score, and through step S310, the level of the modulation coding method of the first frequency band is adjusted to be lowered, and in step S220, the second quality evaluation score of the second frequency band is identified as equal to or higher than the reference evaluation score, and through step S340, the level of the modulation coding method of the second frequency band is maintained.

[0203] However, the present disclosure is not limited thereto, and depending on the communication environment of each frequency band, the level of the modulation coding method of the first frequency band may be maintained, and the level of the modulation coding method of the second frequency band may be adjusted to a lowered level. Furthermore, it is obvious that the levels of the modulation coding methods of each of the first frequency band and the second frequency band may both be adjusted to a lowered level.

[0204] Referring to FIGS. 2, FIGS. 3, FIGS. 5 and FIGS. 6, in one embodiment of the present disclosure, the method of operation of an electronic device (100) may further include the step (S500) of obtaining a first data transmission rate in which first image data processed according to a modulation coding method of a level adjusted through a first frequency band is transmitted.

[0205] In one embodiment of the present disclosure, step S500 may be performed after step S320.

[0206] In step S500, the electronic device (100) can obtain a first data transmission speed through the transmission speed comparison module (114) in which first image data processed according to a modulation coding method of a level adjusted through the first frequency band is transmitted.

[0207] In one embodiment of the present disclosure, the method of operation of the electronic device (100) may further include the step (S510) of the electronic device (100) obtaining a second data transmission rate in which second image data processed according to a modulation coding method of a level adjusted through a second frequency band is transmitted.

[0208] In one embodiment of the present disclosure, step S510 may be performed after step S340.

[0209] In step S510, the electronic device (100) can obtain a second data transmission speed through the transmission speed comparison module (114) in which second image data processed according to a modulation coding method of a level adjusted through the second frequency band is transmitted.

[0210] In one embodiment of the present disclosure, the method of operation of an electronic device (100) may include a step (S600) of comparing the sum of a first data transmission speed and a second data transmission speed with a preset required data transmission speed. In one embodiment of the present disclosure, step S600 may mean a step of identifying whether the sum of the first data transmission speed and the second data transmission speed is lower than the required data transmission speed.

[0211] In one embodiment of the present disclosure, the required data transmission speed may be pre-set to "300 Mbps (Mega bit per second)". However, this is an example embodiment and the present disclosure is not limited thereto. Of course, the required data transmission speed may be set smaller than the above value or larger depending on the resolution of the image (220) to be displayed through the display device (200) or the frequency of the image (220).

[0212] In step S600, the electronic device (100) can compare the sum of the first data transmission speed and the second data transmission speed with the required data transmission speed through the transmission speed comparison module (114).

[0213] In step S600, as it is identified that the sum of the first data transmission speed and the second data transmission speed is equal to or greater than the required data transmission speed, the method of operation of the electronic device (100) can perform step S400.

[0214] In step S600, as it is identified that the sum of the first data transmission speed and the second data transmission speed is less than the required data transmission speed, the method of operation of the electronic device (100) may further include a step (S700) of adjusting the level of the modulation coding method of the second frequency band to be increased.

[0215] In one embodiment of the present disclosure, as the transmission quality of the second image data processed by a second level modulation coding method provided through a second frequency band is good, in step S700, the electronic device (100) can adjust the level of the modulation coding method in the second frequency band to be higher than the second level. In one embodiment of the present disclosure, when the second level is "5", the electronic device (100) can adjust the second level to be higher to "6".

[0216] In one embodiment of the present disclosure, image data processed using a modulation coding method of a level adjusted to be higher may be referred to as third image data. The transmission speed of the third image data may be faster than the transmission speed of the second image data processed using a modulation coding method of a second level. Accordingly, the sum of the transmission speed of the first image data provided by the electronic device (100) through a first frequency band and the transmission speed of the third image data provided through a second frequency band may be equal to or greater than the required data transmission speed.

[0217] At this time, among the first frequency band and the second frequency band, the first frequency band determined to be at a level adjusted so that the level of the modulation coding method is lowered through steps S210 and S310 may be referred to as any one frequency band. Additionally, the second frequency band maintained without lowering the level of the modulation coding method through steps S220 and S340 may be referred to as the remaining frequency band.

[0218] In one embodiment of the present disclosure, the method of operation of the electronic device (100) may include, after step S700, a step (S410) of transmitting first image data processed according to a modulation coding method of a level adjusted through a first frequency band. Additionally, the method of operation of the electronic device (100) may include a step (S430) of transmitting third image data processed according to a modulation coding method of a level adjusted through a second frequency band.

[0219] In one embodiment of the present disclosure, step S410 may be referred to as a step of transmitting first image data processed according to a modulation coding method of a level adjusted to be lowered through one frequency band. Step S430 may be referred to as a step of transmitting third image data processed according to a modulation coding method of a level adjusted to be higher through the remaining frequency band.

[0220] In step S410, the electronic device (100) can transmit first image data processed according to a level of modulation coding method controlled through a first frequency band via a communication interface (140). In step S430, the electronic device (100) can transmit third image data processed according to a level of modulation coding method controlled through a second frequency band via a communication interface (140).

[0221] However, the present disclosure is not limited thereto, and it is understood that the operations of steps S410 and S430 may be performed in a single step.

[0222] FIG. 7a is a flowchart illustrating an operation to adjust the level of a modulation coding method of image data transmitted through a first frequency band according to an embodiment of the present disclosure. FIG. 7b is a flowchart illustrating an operation to adjust the level of a modulation coding method of image data transmitted through a second frequency band according to an embodiment of the present disclosure. Hereinafter, the same reference numerals are assigned to steps identical to those described in FIG. 3 and FIG. 5, and redundant descriptions are omitted.

However, the present disclosure is not limited thereto, FIGS. 7a and FIGS. 7b may include the operation when the electronic device (100) uses one of a plurality of channels included in the 5 GHz band, which is the first frequency band, as the first channel and one of a plurality of channels included in the 6 GHz band, which is the second frequency band, as the second channel to transmit image data (300) to a display device (200).

[0226] In one embodiment of the present disclosure, the "first level" and the "second level" may each have a value of "5". However, the present disclosure is not limited thereto, and the first level and the second level may each be arbitrarily set to any one of a plurality of MCS levels included in an MCS Table provided by a wireless communication network used by the electronic device (100) and the display device (200).

[0227] In one embodiment of the present disclosure, the electronic device (100) may compare a first quality evaluation score with a reference evaluation score in step S210 and compare a second quality evaluation score with a reference evaluation score in step S220.

[0228] In one embodiment of the present disclosure, the electronic device (100) determines that the communication environment of the first frequency band is not smooth as it is identified in step S210 that the first quality evaluation score is lower than the reference evaluation score, and can adjust the level of the modulation coding method in the first frequency band to be lowered. In one embodiment of the present disclosure, the adjusted level may be determined to be "4", which is lower than "5".

[0229] In one embodiment of the present disclosure, the electronic device (100) may compare the correction quality evaluation score of the image data processed by the modulation coding method determined as "4" in step S210 with the reference evaluation score again. At this time, the first image data processed by the modulation coding method of level "5" and the image data processed by the modulation coding method of level "4" may differ in modulation method or coding speed, etc.

[0230] As the electronic device (100) determines in step S210 that the correction quality evaluation score is equal to or higher than the reference evaluation score, it may determine the level of the modulation coding method of the first frequency band to "4" according to step S320. As the electronic device (100) determines in step S210 that the correction quality evaluation score is lower than the reference evaluation score, it may adjust the level of the modulation coding method of the first frequency band to "3" according to step S310 and repeat the operation of step S210.

[0231] In one embodiment of the present disclosure, the electronic device (100) can determine the level of the modulation coding scheme of the second frequency band to "5" in step S340, as in step S220, the second quality evaluation score is identified as being equal to or higher than the reference evaluation score.

[0236] In one embodiment of the present disclosure, the method of operation of the electronic device (100) may further include the step (S800) of transmitting second image data in a multi-input multi-output manner through a second frequency band as it is identified that the sum of the first data transmission rate and the second data transmission rate is lower than the required data transmission rate.

[0237] In step S800, the electronic device (100) can determine the transmission method of the electronic device (100) that transmits image data (300) through the transmission method determination module (115) as a multi-input multi-output method. The electronic device (100) can transmit the second image data through the communication interface (140) via the second frequency band in a multi-input multi-output method.

[0238] At this time, in one embodiment of the present disclosure, since the communication environment of the second channel within the second frequency band is smooth, the electronic device (100) can transmit the second image data processed according to a level modulation coding method that does not lower the level to the display device (200) in a multi-input multi-output manner through the channel within the second frequency band (e.g., the second channel, a channel with an increased width of the second channel, or a channel different from the second channel).

[0239] That is, the electronic device (100) can provide the second image data, processed according to a modulation coding method of a level adjusted to "5", to the display device (200) in a multi-input multi-output manner using a channel included in the 6GHz band.

[0240] Through this, the electronic device (100) can provide image data (300) to the display device (200) at a speed equal to or higher than the required data transmission speed by transmitting image data (300) to the display device (200) in a multi-input multi-output manner using a channel within a second frequency band where the communication environment is good.

[0241] Referring to FIG. 7b, the electronic device (100) can obtain a first quality evaluation score of first image data processed by a first level modulation coding method in a first frequency band and a second quality evaluation score of second image data processed by a second level modulation coding method in a second frequency band in step S100.

The electronic device (100) can transmit the first image data through the communication interface (140) via the first frequency band in a multi-input multi-output method.

[0252] At this time, in one embodiment of the present disclosure, since the communication environment of the first channel within the first frequency band is smooth, the electronic device (100) can transmit the first image data processed according to a level modulation coding method that is not adjusted to lower the level to the display device (200) in a multi-input multi-output manner through the channel within the first frequency band (e.g., the first channel, a channel with an increased width of the first channel, or a channel different from the first channel).

In one embodiment of the present disclosure, the first correction level may be determined to be "4", which is lower than "5".

[0261] In one embodiment of the present disclosure, the electronic device (100) may compare the correction quality evaluation score of the image data processed by the modulation coding method determined as "4" in step S210 with the reference evaluation score again. As the electronic device (100) determines in step S210 that the correction quality evaluation score is equal to or higher than the reference evaluation score, it may determine the level of the modulation coding method of the first frequency band to "4" according to step S320.

[0262] In one embodiment of the present disclosure, the electronic device (100) may determine a second correction level by adjusting the level of the modulation coding scheme in the second frequency band to be lower through step S330, as it is identified in step S220 that the second quality evaluation score is lower than the reference evaluation score.

[0263] In one embodiment of the present disclosure, the electronic device (100) may compare the correction quality evaluation score of the image data processed by the modulation coding method determined as "4" in step S220 with the reference evaluation score again. As the electronic device (100) determines in step S220 that the correction quality evaluation score is equal to or higher than the reference evaluation score, it may determine the level of the modulation coding method of the second frequency band to "4" according to step S340.

[0264] In one embodiment of the present disclosure, the electronic device (100) may obtain a first data transmission speed in which image data processed by a modulation coding method of a first correction level determined as "4" is transmitted through a first frequency band in step S500.

[0277] In one embodiment of the present disclosure, the first graph (900) may represent the transmission speed of image data over time processed according to a high level, for example, a level of "9" modulation coding scheme. Referring to the first graph (900), the image data processed according to the high level modulation coding scheme may continue to have a transmission speed over time compared to the second graph (910) and the third graph (920).

[0278] In one embodiment of the present disclosure, the second graph (910) may represent the transmission speed over time of image data that is processed according to a high-level modulation coding method in some sections of the entire section and according to a low-level modulation coding method in other sections.

[0279] In one embodiment of the present disclosure, the first section (930) and the second section (940) of the entire section may be sections where the communication environment of the channel transmitting video data is not smooth. The second graph (910) illustrates the transmission speed of video data when the level of the modulation coding method is lowered in order to lower the required reception sensitivity and the error rate of data transmission in the first section (930) and the second section (940). The transmission speed of video data may be lowered in the first section (930) and the second section (940).

[0280] The second graph (910) shows the transmission speed of video data processed with a high-level modulation coding method to transmit at a high transmission speed in the remaining sections, excluding the first section (930) and the second section (940) of the entire section.

[0281] However, in this case, during the process of adjusting the level of the modulation coding method according to the communication environment, the reception sensitivity of the image data required by the electronic device (100) or the display device (200) changes, and the transmission speed of the image data changes excessively, so a point (950) occurs where the electronic device (100) cannot stably transmit image data to the display device (200). Accordingly, the quality of the image (220) displayed through the display device (200) may be degraded.

[0282] The electronic device (100) of the present disclosure, with reference to the operation of FIGS. 3 to 8, can adjust the level of the modulation coding method to be lowered when it is identified that the communication environment of the channel is not smooth, and can use the adjusted level by fixing it. At this time, the fixed level may be a level that can satisfy the reception sensitivity and transmission speed of image data required by the display device (200) even if the wireless communication environment between the electronic device (100) and the display device (200) is not smooth.

[0283] Accordingly, the electronic device (100) can transmit image data so that the reception sensitivity and transmission speed of image data required by the display device (200) are satisfied regardless of changes in the communication environment. In addition, unnecessary power consumption that may occur while adjusting the level of the modulation coding method according to changes in the communication environment can be prevented.

[0284] In one embodiment of the present disclosure, the third graph (920) shows the transmission speed of image data processed with a fixed-level modulation coding method over the entire section.

[0285] In one embodiment of the present disclosure, compared with the first graph (900) and the second graph (910), the transmission speed of image data processed with a fixed-level modulation coding method may be lower than the transmission speed of image data processed with a high-level modulation coding method.

[0286] However, the transmission speed of the image data processed using a fixed-level modulation coding method may be equal to or higher than the required data transmission speed required by the display device (200) to display the image (220). Additionally, the level of the modulation coding method does not change in the first section (930) and the second section (940), so the image data can have a stable transmission speed throughout the entire section.

[0287] Accordingly, the electronic device (100) can stably provide image data for displaying an image (220) on a display device (200) regardless of changes in the communication environment, and can reduce power consumption.

[0313] To solve the technical problem described above, one embodiment of the present disclosure provides an electronic device. The electronic device may include a memory in which a program or at least one instruction is stored. The electronic device may include at least one processor. By having at least one processor execute the program or at least one instruction stored in the memory individually or collectively, the electronic device may obtain a first quality evaluation score corresponding to the transmission quality of image data processed according to a first level Modulation and Coding Scheme (MCS) being transmitted through a first frequency band.

The electronic device may compare each of the first quality evaluation score and the second quality evaluation score with a preset reference evaluation score. As the electronic device identifies that at least one of the first quality evaluation score or the second quality evaluation score is lower than the reference evaluation score, it can adjust the level of the modulation coding scheme of at least one frequency band corresponding to the quality evaluation score lower than the reference evaluation score so that it is lower.
