[0041] FIG. 1 is a drawing for explaining an embodiment.

[0042] FIG. 1 illustrates a multi-display system in which an electronic device (100) according to one embodiment operates with a plurality of display devices (e.g., 200, 300, 400).

[0043] Referring to FIG. 1, an electronic device (100) according to one embodiment can provide content such as video, audio, etc. to a first display device (200), a second display device (300), and a third display device (300). The electronic device (100) may include various types of electronic devices capable of providing content to the first display device (200), the second display device (200), and the third display device (300), such as, for example, a set-top box, a DVD player, a Blu-ray disc player, a PC, a game console, etc. (but not limited thereto). The electronic device (100) may be referred to as a source device in terms of providing content, and may also be referred to as a host device, a content providing device, a computing device, etc.

[0044] Referring to FIG. 1, a first display device (200), a second display device (300), and a third display device (400) according to one embodiment can display content received from an electronic device (100) on a screen. The first display device (200), the second display device (300), and the third display device (400) may include various types of electronic devices capable of receiving and outputting content, such as, for example, a smart TV, a network TV, an internet TV, a web TV, an IPTV, a PC, etc. (but not limited thereto). The first display device (200), the second display device (300), and the third display device (400) may be referred to as display devices in terms of receiving and displaying content, and may also be referred to as content receiving devices, sink devices, electronic devices, computing devices, etc. The electronic device (100) may be referred to as the primary device and the display devices (200, 300, 400) may be referred to as secondary devices.

[0045] According to one embodiment, through a multi-display system comprising a plurality of display devices, an image can be displayed on a larger screen by displaying the image on a plurality of display devices arranged side by side. The multi-display system may include various structures, such as arranging the plurality of display devices horizontally, arranging the plurality of display devices vertically, or arranging the plurality of display devices in an NxN configuration. For example, hundreds of display devices may be installed in an NxN configuration in an outdoor public place or on the exterior wall of a building.

[0046] Referring to FIG. 1, a first display device (200), a second display device (300), and a third display device (400) are arranged side-by-side and connected horizontally so that an image can be displayed on a larger screen. According to one embodiment, an electronic device (100) can transmit video frames to provide content to a plurality of display devices (200, 300, 400). Video frames can be transmitted from the electronic device (100) to the first display device (200), the second display device (300), and the third display device (400) in the direction (1).

[0047] Meanwhile, a multi-display system according to one embodiment may require diagnosis of the state of each of the multiple display devices. For example, since a display device installed outdoors is exposed to the external environment, it may be necessary to diagnose whether it maintains a temperature, humidity, etc. suitable for operating the display device. The electronic device (100) may perform diagnosis of the state of the temperature, humidity, etc. of each display device when installing the multiple display devices or at a predetermined interval.

[0048] According to one embodiment, when transmitting a video frame, the electronic device (100) may transmit the frame by including a command requesting status data for diagnosing a display device in the remaining data space other than the video data space of the frame. The electronic device (100) may include a command requesting status data of a type to be collected from each display device in a part of the data space of the video frame.

[0049] According to one embodiment, when an electronic device (100) transmits a video frame, it may transmit the frame by including control data that commands each display device to perform an action in the remaining data space other than the video data space of the frame.

[0050] Referring to FIG. 1, an image frame transmitted from an electronic device (100) is sequentially transmitted to a first display device (200), a second display device (300), and a third display device (400) in the direction (1), and based on a command requesting state data included in the image frame, a request for and acquisition of state data can be performed from each of the first display device (200), the second display device (300), and the third display device (400). After the acquisition of state data from the third display device (400) is completed, the image frame containing the state data of the first, second, and third display devices (200, 300, 400) can be transmitted to the electronic device (100) in the direction (2), which is the reverse direction of the transmission direction.

[0051] According to one embodiment, an electronic device (100) can transmit a command requesting status data for all of a plurality of display devices (e.g., 200 displays) in a loop format that is sequentially transmitted to a plurality of display devices, with the command carried in the data space (e.g., 74 Kbyte) remaining outside the image data space in a single image frame (e.g., 16 msec). As the image frame is transmitted to each display device, status data is collected from each display device, and once the status data of the last display device is collected, the image frame containing the status data of all display devices can be transmitted to the electronic device (100) in the reverse direction of transmission. Accordingly, the electronic device (100) can collect status data for all display devices in a short period of time.

[0052] According to one embodiment, the electronic device (100) requests and collects one type of status data for each of the multiple display devices or all requestable types of status data for each of the multiple display devices through the transmission and reception of a single image frame, rather than requesting one type of status data for any one of the multiple display devices through the transmission and reception of a single image frame, thereby improving the diagnostic speed based on status data for all of the multiple display devices and shortening the diagnostic time.

[0053] In addition, according to one embodiment, by transmitting control data for each of the plurality of display devices using a single image frame, the control speed for all of the plurality of display devices can be improved and the control time can be shortened.

[0054] Accordingly, when using a multi-display system, efficient diagnosis and control of multiple display devices can be achieved.

[0055] FIG. 1 is illustrated to explain one embodiment and is not limited thereto.

[0056] FIG. 2 is a drawing for explaining an example of a multi-display system arranged in an NxN shape according to one embodiment.

[0057] FIG. 2 illustrates a multi-display system in which nine display devices (200, 300, 400, 500, 600, 700, 800, 900, 1000) according to one embodiment are configured in a 3x3 shape.
