That is, the time synchronization units 177_1 and 177_2 may compare the identifiers of the scaled frames through communication with each other, and if the identifiers of the frames are the same, the time synchronization units 177_1 and 177_2 may output the corresponding frames to the display units 180. Accordingly, the timing of each frame is corrected, and as shown in FIG. 17D, an image of content may be displayed on one large screen.

Next, an embodiment in which the arrangement of each device is automatically or manually set for normal interworking between the screen of the first display device 100_1 and the screen of the second display device 100_2 will be described.

FIG. 18A illustrates a state in which the first display device 100_1 and the second display device 100_2 are normally disposed, and FIG. 18B illustrates the first display device 100_1 and the second display device ( 100_2) is abnormally disposed. That is, it is assumed that the first display apparatus 100_1 is disposed at the left side and the second display apparatus 100_2 is disposed at the right side in a normal arrangement.

When the first display device 100_1 and the second display device 100_2 are abnormally arranged, screen interlocking is also abnormally performed, and as shown in FIG. 18B, content playback is performed on one large screen. May not be displayed smoothly.

Referring to FIG. 19, each of the first display apparatus 100_1 and the second display apparatus 100_2 may display a plurality of batch setting items for batch setting. The plurality of arrangement setting items may include a left arrangement setting item 710 and a right arrangement setting item 720. When the left arrangement setting item 710 displayed on the screen of the first display apparatus 100_1 is selected through a button input of the remote control apparatus 200, the first display apparatus 100_1 may be set to be arranged on the left side. have. When the right arrangement setting item 730 is selected through the button input of the remote control apparatus 200 on the screen of the second display apparatus 100_2, the second display apparatus 100_2 may be set to be disposed on the right side. .

According to an embodiment, the arrangement setting item may be displayed when each display apparatus 100 enters the twin mode.

Referring to FIG. 20, the first display apparatus 100_1 may include a first left speaker 185_1 and a first right speaker 185_2, and the second display apparatus 100_2 may include a second left speaker 185_3. And a second right speaker 185_4. The remote control apparatus 200 may be positioned in front of the first display apparatus 100_1 and the second display apparatus 100_2, and the first display apparatus 100_1 and the second display apparatus 100_2 may be in close contact with each other. Assume

The control unit 170 of each display apparatus 100 may sequentially output a test voice signal through the provided speaker. For example, the test voice signal may be output in the order of the first left speaker 185_1, the first right speaker 185_2, the second left speaker 185_3, and the second right speaker 185_4. The strength of each test speech signal may be the same.

The microphone 291 of the remote control apparatus 200 may receive a test voice signal output from each speaker. The controller 280 of the remote control apparatus 200 may calculate a gain of each test voice signal based on the received test voice signal. For example, the gain G1 of the test voice signal output from the first left speaker 185_1 and the test voice signal output from the second right speaker 185_4 due to the distance difference between each speaker and the remote control apparatus 200. One of the gains G4 may be the highest gain and the other may be the lowest gain. In addition, since the first display apparatus 100_1 and the second display apparatus 100_2 are in close contact with each other, the gain G2 and the second left speaker 185_3 of the test voice signal output from the first right speaker 185_2 are output. The magnitude of the gain G3 of the tested test speech signal may be similar. The first display apparatus 100_1 may receive the gain of each test voice signal from the remote control apparatus 200, and may determine its own position and the position of the second display apparatus 100_2 based on the received gain. . For example, when the remote control apparatus 200 is located closest to the first left speaker 185_1, the test voice signal output from the first left speaker 185_1 has the largest magnitude, and the second right speaker ( The test voice signal output from 185_4 may be the smallest. Each of the first display apparatus 100_1 and the second display apparatus 100_2 recognizes a location of the provided speaker. Accordingly, since the test voice signal output from the first left speaker 185_1 has the largest magnitude, the first display apparatus 100_1 may recognize that the first display apparatus 100_1 is disposed on the left side of the second display apparatus 100_2. Since the test voice signal output from the speaker 185_4 is the smallest, it may be recognized that the second display apparatus 100_2 is disposed on the right side of the first display apparatus 100_2. In this case, the first display apparatus 100_1 may check that the arrangement of each display apparatus 100 is normal. If the first display apparatus 100_1 has an abnormal arrangement of each display apparatus 100, as shown in FIG. 22 to be described later, the first display apparatus 100_1 may display the screen arrangement guide window 731.

62 to 68, it is assumed that audio channels of the display apparatuses 100_1 and 100_2 are two channels, and screens are linked to each other to provide content. When the audio channel is two channels, each display apparatus 100_1 and 100_2 may include two speakers. In FIG. 62, each of the two speakers is illustrated as being implemented at the lower left and lower right portions of the display apparatus 100, but the positions of the two speakers are not limited thereto.

For convenience of description, in FIG. 62, two display apparatuses 100_1 and 100_2 are linked to each other to provide one content. However, the number of display apparatuses that are linked is not limited thereto.

Referring to FIG. 62A, when an image of content is displayed on a merged screen of the first display apparatus 100_1 and the second display apparatus 100_2, a sound image of audio of the content may be formed. Can be. In order to form a sound image suitable for an image of content, the first left speaker 185_1 and the first right speaker 185_2 included in the first display device 100_1 positioned on the left output only left audio L. FIG. The second left speaker 185_3 and the second right speaker 185_4 included in the second display apparatus 100_2 located on the right may output only right audio R. FIG.

The sound image refers to a focal point in which each of the sounds (eg, vocals, musical instruments, etc.) included in the audio of the content is virtually formed. Accordingly, the user may feel that each of the sounds are heard at the corresponding focus. For example, when a sound image of a sound corresponding to the piano is formed on the left side of the user, the user may recognize that the sound of the piano is generated from the left side, and a sound image of a sound corresponding to the human voice is formed on the front of the user. In this case, the user can recognize that the human voice is generated from the front.

When video and audio of content are simultaneously provided through a display device such as a TV, an optimized content may be provided when the position of an object displayed on the screen matches the position of a sound image of audio generated by the object. have.

However, in the case of FIG. 62A, a virtual sound source may be formed between the speakers 185_1 and 185_2 or 185_3 and 185_4 that output the same audio. As the virtual sound source is formed, the audio of the output content may not have a sound image as much as the image of the content, and the sound image may be formed as narrow as the interval between the audio VLA and the VRA output from the virtual sound sources. Therefore, since the image of the content and the sound of the audio do not match, it may not be able to provide an optimized content viewing environment.

Referring to FIG. 62B, in order to prevent the sound image from being narrowly formed by the virtual sound sources as shown in FIG. 62A, the first display apparatus 100_1 uses the first left speaker 185_1. The left audio LA may be output through the first audio LA, and the audio may not be output through the first right speaker 185_2 (MUTE). The second display apparatus 100_2 may output the light audio RA through the second right speaker 185_4, and may not output the audio through the second left speaker 185_3 (MUTE). In this case, since the virtual sound source is not formed, the audio of the output content may have a sound image that is as wide as the image of the content. However, since the first right speaker 185_2 and the second left speaker 185_3 do not output audio, the output levels of the audio output by the first left speaker 185_1 and the second right speaker 185_4 are all. The speaker 185_1 to 185_4 may be lower than the audio output level when audio is output. Therefore, in the case of FIG. 62B, the sound image may be blurred.

Referring to FIG. 62C, in order to solve the above-described problems, the first display apparatus 100_1 according to an embodiment of the present invention may include left audio LA or left audio LA and right audio RA. Center audio (LCA) can be generated. In addition, the second display apparatus 100_2 may generate the center audio RCA based on the right audio RA or the left audio LA and the right audio RA. The center audio LCA generated by the first display apparatus 100_1 and the center audio RCA generated by the second display apparatus 100_2 may be the same or different.

Accordingly, the sound image may be formed as wide as the image of the content, and the output level of the audio may also be higher than that of FIG. 62 (b).

Referring to FIG. 63, the first display apparatus 100_1 may include the first left speaker 185_1 and the first right speaker 185_2 as the audio signal processor 178_1, the amplifier 184_1, and the audio output unit. It may include.

The audio signal processor 178_1 may receive an audio signal of content from the demodulator 132, the network interface unit 133, or the external device interface unit 135. For example, when the audio signal of the content is a two-channel stereo signal, the audio signal processor 178_1 may receive a left audio signal and a right audio signal as the audio signal of the content.

The audio signal processor 178_1 may process the audio signals (the left audio signal and the write audio signal) of the received content and output the audio signal of the processed content to the amplifying unit 184_1. For example, the audio signal processor 178_1 may perform a processing operation to reduce a noise component of the audio signal of the content, or may output an audio signal of the content based on an audio output mode and / or an audio effect of the first display apparatus 100_1. Can be processed. The audio output mode is automatically or manually set according to the category of the content, and may include, for example, a movie mode, a sports mode, a general mode, and the like. The audio effect may mean a stereoscopic effect, equalizing, or the like. The audio output mode and the audio effect are not limited to the above examples, and may include various audio output modes and audio effects that can be set in a known display device.

The audio signal processor 178_1 may be included in the controller 170 illustrated in FIG. 1 or may be implemented as a single chip with the controller 170, but is not limited thereto. It may be implemented as.

The amplifier 184_1 may receive an audio signal (left audio signal and / or write audio signal) of the content processed by the audio signal processor 178_1 and amplify the received audio signal. The voltage level of the audio signal of the content processed by the audio signal processor 178_1 may have a low voltage level (eg, less than 1 mV). In order for the first left speaker 185_1 and the first right speaker 185_2 to output audio corresponding to the audio signal of the content, the voltage level of the audio signal to be output must be equal to or greater than a predetermined level (for example, 0.1V or more). Therefore, the amplifier 184_1 amplifies the audio signal of the content so that the audio signal of the content can be output through the first left speaker 185_1 and the first right speaker 185_2, and the audio of the amplified content is amplified. The signal may be transmitted to the first left speaker 185_1 and the first right speaker 185_2.

Structures and operations of the elements 178_1, 184_1, 185_1, and 185_2 of the first display apparatus 100_1 illustrated in FIG. 63 may be substantially the same or similarly applied to the second display apparatus 100_2.

Referring to FIG. 64, the first display apparatus 100_1 may be connected to the second display apparatus 100_2 to operate in a twin mode (S1000).

The twin mode may be a mode in which a first screen of the first display apparatus 100_1 and a second screen of the second display apparatus 100_2 may be linked to each other and used as one merged screen. As described above, detailed description thereof will be omitted.

The display apparatus 100 may receive an audio signal of content (S1100).

For example, when the audio signal of the content is a two-channel stereo signal, the display apparatus 100 may receive a left audio signal and a right audio signal as the audio signal of the content.

When the content is broadcast content, the tuner 131 receives a broadcast signal for a specific broadcast channel, and the demodulator 132 separates the received broadcast signal into a video signal, an audio signal, and a data signal associated with a broadcast program. Can be.

According to an embodiment, the display apparatus 100 may receive an audio signal of content through the network interface unit 133 and the external device interface unit 135.

The display apparatus 100 may generate a center audio signal based on the audio signal of the received content (S1200).

When the first display apparatus 100_1 generates the center audio signal LC, the center audio signal LC may be generated by the audio signal processor 178_1 or the amplifier 184_1. The center audio signal LC may be substantially the same as or similar to the mono audio signal.

The display apparatus 100 may transmit one audio signal among the audio signals of the received content and the generated center audio signal to each of the speakers (S1300).

Any one audio signal may correspond to a position where the display apparatus 100 is disposed. For example, when the first display apparatus 100_1 is disposed at the left side and the second display apparatus 100_2 is disposed at the right side as illustrated in FIG. 62C, the first display apparatus 100_1 is left audio. The signal L may be transmitted to the first left speaker 185_1, and the center audio signal LC may be transmitted to the first right speaker 185_2. The second display apparatus 100_2 may transmit the center audio signal RC to the second left speaker 185_3, and may transmit the write audio signal R to the second right speaker 185_4.

Steps S1200 and S1300 will be described in detail with reference to FIGS. 65 to 68.

Referring to FIG. 65, the audio signal processor 178_1 of the first display apparatus 100_1 and the audio signal processor 178_2 of the second display apparatus 100_2 are written as left audio signals L and light as audio signals of content. The audio signal R may be received.

Each of the audio signal processors 178_1 and 178_2 may generate center audio signals LC and RC based on the left audio signal L and the right audio signal R, respectively.

Referring to FIG. 66, the audio signal processor 178_1 or 178_2 may synthesize (or sum; L + R) the left audio signal L and the right audio signal R to generate a center audio signal LC or RC. Can be. According to an embodiment, as illustrated in FIG. 66, the controller 170 of the first display apparatus 100_1 or the second display apparatus 100_2 gives a preset weight to the synthesized center audio signal LC or RC. (E.g., 50%) or adjust the output level of the synthesized center audio signal (LC or RC) (e.g., adjust the output level of the center audio signal by about -6 to -8 dB, i.e. reduce the output level). The audio signal processor 178_1 or 178_2 may be controlled.

The generated center audio signal LC or RC may be substantially the same as or similar to a mono audio signal. The operation of the audio signal processor 178_1 or 178_2 to generate the center audio signal LC or RC based on the left audio signal L and the right audio signal R is not limited to the method described with reference to FIG. 65. The audio signal may be generated by various known algorithms or methods for generating a mono audio signal using the stereo audio signal.

65 and 66, when a center audio signal is generated, the center audio signal LC generated by the first display apparatus 100_1 and the center audio generated by the second display apparatus 100_2 are generated. The signal RC may be the same. However, when generating the center audio signals LC and RC through known algorithms or methods, the center audio signal LC generated by the first display apparatus 100_1 and the second display apparatus 100_2 may be generated. The generated center audio signal RC may be different from each other.

The audio signal processor 178_1 or 178_2 transmits one of the left audio signal L and the right audio signal R and the generated center audio signal LC or RC to the amplifying unit 184_1 or 184_2. Can be.

Referring to FIG. 62C, the first display apparatus 100_1 is disposed at the left side, and the second display apparatus 100_2 is disposed at the right side. Accordingly, the audio signal processor 178_1 of the first display apparatus 100_1 transmits the left audio signal L and the center audio signal LC to the amplifier 184_1 and the audio signal of the second display apparatus 100_2. The processor 178_2 may transmit the center audio signal RC and the write audio signal R to the amplifier 184_2.

The amplifier 184_1 of the first display apparatus 100_1 amplifies each of the received left audio signal L and the center audio signal LC, and amplifies the left left audio signal AL by the first left speaker 185_1. The amplified center audio signal ALC may be transmitted to the first right speaker 185_2.

The amplifier 184_2 of the second display apparatus 100_2 amplifies each of the received center audio signal RC and the right audio signal R, and converts the amplified center audio signal ARC to the second left speaker 185_3. The amplified light audio signal AR may be transmitted to the second right speaker 185_4.

Since the amplifier 184 does not synthesize the left audio signal L and the right audio signal R, the audio signal processor 178 transmits only one audio signal of the audio signal of the content to the amplifier 184. Can be. Any one audio signal transmitted by the audio signal processor 178 may correspond to a position where the display apparatus 100 is disposed. That is, as illustrated in FIG. 67, the audio signal processor 178_1 of the first display apparatus 100_1 transmits only the left audio signal L to the amplifier 184_1 and the audio signal of the second display apparatus 100_2. The processor 178_2 may transmit only the write audio signal R to the amplifier 184_2.

The amplifier 184 may generate the center audio signal LC or RC using only one of the received audio signals L or R. To this end, the amplifier 184 may include a filter. In the audio of the content, a low frequency frequency sound, which generally occurs from a human voice or an object, may correspond to a mono component. Accordingly, the center audio signal LC or RC may be formed around a low frequency component corresponding to a human voice or an object sound. The low frequency component may mean a frequency component less than a reference frequency of any one of 1 kHz to 4 kHz, but is not limited thereto.

Therefore, the filter is implemented as a low pass filter (LPF) or a band pass filter (BPF) for filtering only the corresponding frequency components in the left audio signal (L) or the right audio signal (R). It may be, but is not limited thereto. For example, the frequency component filtered using the low pass filter or the band pass filter may include a frequency component less than a reference frequency of any one of 1 kHz to 4 kHz. The amplifier 184 may filter the left audio signal L or the right audio signal R using the filter, and generate a center audio signal LC or RC similar to the mono audio signal as a result of the filtering.

Referring to FIGS. 68A and 68B, when the filter included in the amplifier 184 is a low pass filter, the amplifier 184_1 included in the first display apparatus 100_1 may be described with reference to FIG. As shown in a), the left audio signal L may be filtered to generate the center audio signal LC, and the amplifier 184_2 included in the second display apparatus 100_2 may be illustrated in FIG. 68B. As shown in FIG. 5, the center audio signal RC may be generated by filtering the light audio signal R. FIG.

In this case, the center audio signal LC generated by the first display apparatus 100_1 and the center audio signal RC generated by the second display apparatus 100_2 may be different from each other.

In FIG. 67, the amplifier 184 includes a filter for convenience of description, but the filter is not necessarily included in the amplifier 184, and may be disposed between the audio signal processor 178 and the amplifier 184. It may be implemented.

The amplifier 184 may amplify any one audio signal L or R and the center audio signal LC or RC, and transmit each of the amplified audio signals to each of the speakers as described with reference to FIG. 65.

64 will be described again.

Each of the speakers may output audio corresponding to each of the received audio signals (S1400).

The first left speaker 185_1 of the first display apparatus 100_1 outputs left audio corresponding to the received left audio signal, and the first right speaker 185_2 outputs center audio corresponding to the received center audio signal. can do. The second left speaker 185_3 of the second display apparatus 100_2 may output center audio corresponding to the center audio signal, and the second right speaker 185_4 may output light audio corresponding to the write audio signal.

As a result, a sound image as shown in Fig. 62C can be formed. Therefore, when providing one piece of content by interworking with the first display device 100_1 and the second display device 100_2, the size of the image of the content provided on the merged screen of the display devices 100_1 and 100_2 is optimized. Audio may be provided. This will be described with reference to FIG. 69.

Referring to FIG. 69, the arrangement of sound sources formed according to an embodiment of the present invention may be based on the BS775-1 standard of the International Telecommunication Union-Radiocommunication Sector (ITU-R). Recommended speaker layout for channel playback ”.

According to the recommended speaker arrangement, the display apparatuses 100_1 and 100_2 according to the embodiment of the present invention may have a sound source of left audio LA and a sound source of light audio RA based on the viewing position W_POS of the user. It may be arranged to achieve about 60 degrees.

In addition, the virtual center audio VCA may be formed by the center audios LCA and RCA. According to the recommended speaker arrangement, the distances of the sound source of the left audio LA, the sound source of the light audio RA, and the sound source of the virtual center audio VCA may be the same from the viewing position W_POS of the user.

Accordingly, the display apparatus 100_1 or 100_2 may reduce the output level of the center audios LCA and RCA in order to cause the sound source of the virtual center audio VCA to be formed behind the center audios LCA and RCA. Can be. That is, the controller 170 of the display apparatus 100_1 or 100_2 may determine the output levels of the first right speaker 185_2 and the second left speaker 185_3 and the first left speaker 185_1 and the second right speaker 185_4. The output level of the center audios LCA and RCA can be reduced by decreasing the output level of the audio. For example, the display apparatuses 100_1 and 100_2 may adjust the output level of the center audios LCA and RCA to -6dB to -8dB, but the output level to be adjusted is not limited thereto.

However, when the display apparatuses 100_1 and 100_2 are implemented as curved TVs according to an exemplary embodiment, the center audios of the curved TVs are located behind the center audios LCA and RCA illustrated in FIG. 69. can do. Therefore, the display apparatuses 100_1 and 100_2 may not adjust the output level of the center audios or change the degree of adjustment as appropriate.

That is, the display apparatuses 100_1 and 100_2 according to the embodiment of the present invention may provide an effect of improving the realism and immersion by providing an optimized audio output when the user views the content.

The present invention described above can be embodied as computer readable codes on a medium in which a program is recorded.
