Furthermore, although terms such as "first," "second," etc. may be used herein to describe various elements, such terms are used only to distinguish one element or operation from another element or operation described in the same technical terms. Unless the context clearly dictates otherwise, the terms do not specifically refer or imply an order or sequence nor are they intended to limit the invention.

Fig. 1 shows an audio/video playback system 100 according to an embodiment of the disclosure. The video playback system 100 includes a first playback device 110, a second playback device 120, and a processing device 200. The first playback device 110 is disposed on a first side (e.g., left side) of the av playback system 100. The second playback device 120 is disposed on a second side (e.g., right side) of the av playback system 100. In one embodiment, the first playback device 110 and the second playback device 120 are display devices (e.g., panel screens) for displaying video and audio. In other embodiments, the first playback device 110 and the second playback device 120 can be speakers or speakers installed on the display for playing audio only.

The processing device 200 may be a Central Processing Unit (CPU), a System on Chip (SoC), an application processor, or a server with a specific function. The processing device 200 is electrically connected to the first playback device 110 and the second playback device 120, and the processing device 200 can determine the relative positions (e.g., left and right) of the first playback device 110 and the second playback device 120 according to the first position parameter corresponding to the first playback device 110 and the second position parameter corresponding to the second playback device 120. The first position parameter and the second position parameter are obtained in a manner to be described in detail later.

The processing device 200 is configured to receive video and audio data Ds, such as: data transmission is performed through a transmission line and the Internet. The video and audio data Ds may come from a server, a storage unit (e.g. a usb disk) or other electronic devices. In one embodiment, the video data Ds includes audio data D10. After the processing device 200 receives the video data Ds, the processing device 200 obtains the first channel audio D11 and the second channel audio D12 from the audio data D10 according to the first position parameter and the second position parameter, and transmits the first channel audio D11 to the first playback device 110 and the second channel audio D12 to the second playback device 120.

Accordingly, the processing device 200 can transmit different channel audio according to the positions of the first playback device 110 and the second playback device 120, so the audio transmission effect is more stereoscopic and the sound channel situation is improved. For example, the first channel audio D11 may be a left channel audio, the second channel audio D12 may be a right channel audio, and the processing device 200 determines the positions of the playing devices 110 and 120 according to the position parameters, so that the first playing device 110 on the left side can play the left channel audio and the second playing device 120 on the right side can play the right channel audio. As shown in fig. 1, although the first playing device 110 has two speakers 110L, 110R, the two speakers 110L, 110R will be used to play the same first channel audio D11 under the control of the processing device 200. Similarly, the two speakers 120L, 120R of the second playing device 120 are also used to play the same second channel audio D12.

In another embodiment, the video data Ds further includes video data D20, such as picture data. The first playback device 110 and the second playback device 120 can receive the video data D20 through the processing device 200 to display corresponding video frames. In some embodiments, the processing device 200 is further configured to obtain the first position image D21 and the second position image D22 from the image data D20 according to the first position parameter and the second position parameter, so as to transmit the first position image D21 to the first playback device 110 and transmit the second position image D22 to the second playback device 120. For example, the first position image D21 and the second position image D22 can be a left half and a right half of a full image, respectively, and the first playback device 110 and the second playback device 120 are used to display the left half or the right half of the full image, respectively, so as to merge the full image.

In fig. 1, two speakers 110L and 110R are respectively disposed on the left side and the right side of the first playback device 110. The left and right sides of the second playback device 120 are also respectively provided with two speakers 120L, 120R. However, the speaker is not limited to the arrangement shown in fig. 1. In other embodiments, the first playback device 110 may comprise a display and a speaker, and the display and the speaker are connected to the processing device 200 respectively. Alternatively, in other embodiments, the speaker may be mounted inside, behind, or below the playback device.

The processing device 200 is used for obtaining the subwoofer audio D13 from the audio data D10 according to the third position parameter corresponding to the third playback device 130, and transmitting the subwoofer audio D13 to the third playback device 130. That is, in this embodiment, the third playing device 130 located at the center is dedicated to playing the subwoofer audio D13.

In another embodiment, the processing device 200 does not transmit the subwoofer audio D13 to the third playback device 130. Referring to fig. 2B, the third playback device 130 includes a first channel speaker 130L and a second channel speaker 130R. The processing device 200 transmits the first channel audio D11 to the first channel speaker 130L and the second channel audio D12 to the second channel speaker 130R to enhance the stereoscopic effect of the first channel audio D11 and the second channel audio D12. In this embodiment, the third playback device 130 has set therein position parameters (e.g., left channel and right channel) corresponding to the first channel speaker 130L and the second channel speaker 130R, so that the processing device 200 can determine the relative positions of the first channel speaker 130L and the second channel speaker 130R accordingly.

In yet another embodiment, the processing device 200 does not transmit the subwoofer audio D13 to the third playback device 130. Referring to fig. 2C, when the processing device 200 transmits the first channel audio D11 to the first playback device 110 and transmits the second channel audio D12 to the second playback device 120, the processing device 200 may be further configured to turn off the first channel speaker 130L and the second channel speaker 130R of the third playback device 130. In this embodiment, the processing device 200 transmits the video data D20 to the third playback device 130, so that the third playback device 130 is only used for displaying video images, and does not need to play audio.

In the above embodiment with three playback devices, the processing device 200 obtains the third position video D23 from the video data D20 according to the third position parameter, so as to transmit the third position video D23 to the third playback device 130. For example, the third position image D23 may be a middle part image of a full image, so that the first playback device 110, the second playback device 120, and the third playback device 130 can be merged to display a complete full image.

In another embodiment, please refer to fig. 2D, the video playback system 100 includes a plurality of first playback devices 110, second playback devices 120, and third playback devices 130. The third playback device 130 is disposed between the first playback device 110 and the second playback device 120, and stacked up and down. As in the foregoing embodiments of fig. 2A-2C, the processing device 200 may transmit the subwoofer audio D13 to the third playback device 130, or transmit the first channel audio D11 and the second channel audio D12 to the first channel speaker 130L and the second channel speaker 130R, respectively. Similarly, the processing device 200 can also turn off the first channel speaker 130L and the second channel speaker 130R of the third playback device 130.

Referring to fig. 3, an embodiment of "there are a plurality of other playback devices between the first playback device 110 and the second playback device 120" is described herein. In fig. 3, similar components related to the embodiment of fig. 1 are denoted by the same reference numerals for easy understanding, and the specific principles of the similar components have been described in detail in the previous paragraphs, which are not repeated herein if necessary for description if they have a cooperative relationship with the components of fig. 3.

In an embodiment, the video playback system 100 further includes a fourth playback device 140 and a fifth playback device 150. The playback devices 110, 120, 140, and 150 are arranged along a horizontal or vertical direction, and the processing device 200 may also store position parameters corresponding to the playback devices 110, 120, 140, and 150. The fourth playback device 140 is disposed between the first playback device 110 and the second playback device 120, and is adjacent to the first playback device 110. The fourth playback device 140 includes a third channel speaker 140L and a fourth channel speaker 140R. The fifth playback device 150 is disposed between the first playback device 110 and the second playback device 120, and is adjacent to the second playback device 120. The fifth playback device 150 includes a fifth channel speaker 150R and a sixth channel speaker 150L.

The fourth playback device 140 stores speaker position parameters representing the relative positions of the third channel speaker 140L and the fourth channel speaker 140R on the fourth playback device 140. Similarly, the fifth playback device 150 stores position parameters representing the relative positions of the fifth channel speaker 150R and the sixth channel speaker 150L on the fifth playback device 150. The processing device 200 can obtain the position parameters to transmit the corresponding audio.

In another embodiment, the fourth playback device 140 and the fifth playback device 150 can be used for playing back subwoofer audio. When the processing device 200 transmits the first channel audio D11 (e.g., left channel audio) to the first playback device 110 and the second channel audio D12 (e.g., right channel audio) to the second playback device 120, the processing device 200 is further configured to transmit the first channel audio D11 to the third channel speaker 140L and the second channel audio D12 to the fifth channel speaker 150R. In addition, the processing apparatus 200 obtains the subwoofer audio D13 from the audio data D10, and transmits the subwoofer audio D13 to the fourth channel speaker 140R and the sixth channel speaker 150L to enhance the stereo effect of the audio.

In yet another embodiment, the fourth playback device 140 and the fifth playback device 150 can be used to enhance the first channel audio D11 and the second channel audio D12. When the processing device 200 transmits the first channel audio D11 (e.g., left channel audio) to the first playback device 110 and the second channel audio D12 (e.g., right channel audio) to the second playback device 120, the processing device 200 transmits the first channel audio D11 to the third channel speaker 140L, but turns off the fourth channel speaker 140R. Similarly, the processing device 200 transmits the second channel audio D12 to the fifth channel speaker 150R, but turns off the sixth channel speaker 150L. By adjusting the audio configuration, the same audio can be played in a centralized manner, and the influence of the fourth channel speaker 140L and the fifth channel speaker 150R located in the center on the stereo playing effect of the audio can be avoided.

Fig. 4 is a flowchart illustrating an audio/video processing method according to an embodiment of the disclosure. The video and audio processing method comprises steps S401 to S404.
