Description

[Technical field]

[0001] This specification discloses a technique related to a digital signage system. [Background technology]

[0002] A digital signage system is a system that transmits information by setting up video display devices such as displays and projectors in places where people gather, such as stores, commercial facilities, public facilities, stations, and offices (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3240922 Summary of the Invention [Problem to be solved by the invention]

[0004] There was a demand to use the digital signage system as a security system for the store. [Means for solving the problem]

[0005] A digital signage system according to one embodiment disclosed in the present specification includes a first video signal output device that outputs a first video signal showing a preset video, a second video signal output device that outputs a second video signal showing a video captured by a security camera, a signal switching device that selectively outputs either the first video signal or the second video signal, a video display device that displays a video based on the video signal output from the signal switching device, and an emergency notification device that can be operated by a store clerk in an emergency. The signal switching device normally outputs the first video signal to the video display device, and outputs the second video signal to the video display device in response to an operation of the emergency notification device. According to the digital signage system of this embodiment, when an emergency occurs and the emergency notification device is operated, the video displayed on the video display device can be switched to a video captured by a security camera. This allows many people to be notified of the occurrence of an emergency through the video captured by the security camera, and encourages a quick response to the emergency.

[0006] The technology disclosed in this specification is not limited to the form of a digital signage system, but can also be realized in the form of an apparatus that constitutes a digital signage system, a computer program for controlling a digital signage system, and a control method for a digital signage system. [Brief description of the drawings]

[0007] [Figure 1] FIG. 1 is an explanatory diagram showing a configuration of a digital signage system. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] FIG. 1 is an explanatory diagram showing the configuration of a digital signage system 100. The digital signage system 100 is a system that combines a digital signage function and a crime prevention function. The digital signage system 100 is a system that is installed in places where people gather, such as stores, commercial facilities, public facilities, stations, and offices. The digital signage system 100 includes a first video signal output device 110, a second video signal output device 120, a signal switching device 130, a video display device 140, and an emergency notification device 150.

[0009] The first video signal output device 110 in the digital signage system 100 is a first video signal output device that outputs a first video signal VS1 that displays a preset video. The first video signal output device 110 may be any device that outputs a video signal that can be played back on the video display device 140. For example, the first video signal output device 110 may be a DVD player, a personal computer, a tablet terminal, a smartphone, or the like. In this embodiment, the first video signal VS1 is a video signal that complies with the HDMI standard ("HDMI" is a registered trademark).

[0010] The second video signal output device 120 in the digital signage system 100 is a second video signal output device that outputs a second video signal VS2 that displays an image captured by a security camera 122. The second video signal output device 120 is a recording device (digital recorder) that records an image captured by the security camera 122 in the security camera system. The security camera 122 may be installed indoors or outdoors. In this embodiment, the second video signal VS2 is a video signal that complies with the HDMI standard.

[0011] The signal switching device 130 of the digital signage system 100 selectively outputs either the first video signal VS1 or the second video signal VS2. The signal switching device 130 is an HDMI switch (HDMI selector). The signal switching device 130 normally outputs the first video signal VS1 to the video display device 140. The signal switching device 130 outputs the second video signal VS2 to the video display device 140 in response to the operation of the emergency notification device 150.

[0012] The image display device 140 of the digital signage system 100 displays an image based on the image signal output from the signal switching device 130. The image display device 140 may be a transmissive LED display (seal-through LED display), a non-transmissive LED display, a liquid crystal display, a projector, or the like.

[0013] The digital signage system 100 may include an in-store monitor 160. The in-store monitor 160 is a video display device installed in the backyard of the store. Like the video display device 140, the in-store monitor 160 displays a video based on a video signal output from the signal switching device 130.

[0014] The emergency notification device 150 of the digital signage system 100 is a device configured to be operable by a store clerk in an emergency, a so-called emergency button. A signal indicating the operation of the emergency notification device 150 is input to the signal switching device 130 via the emergency receiving device 152. The signal switching device 130 outputs a second video signal VS2 to the video display device 140 in response to the signal from the emergency receiving device 152. The communication between the emergency notification device 150 and the emergency receiving device 152 may be wireless or wired. The digital signage system 100 may include a security rotating light 154 that operates in response to the operation of the emergency notification device 150.

[0015] According to the digital signage system 100 described above, when an emergency occurs and the emergency notification device 150 is operated, the image displayed on the image display device 140 can be switched to the image from the security camera 122. This makes it possible to notify many people of the occurrence of the emergency through the image from the security camera 122, and to encourage a rapid response to the emergency.

[0016] The technology disclosed in this specification is not limited to the above-mentioned embodiment, example, and modification, and can be realized in various configurations without departing from the spirit thereof. For example, among the technical features in the above-mentioned embodiment, example, and modification, those corresponding to the technical features in each form described in the summary of the invention can be appropriately replaced and combined to solve some or all of the above-mentioned problems or to achieve some or all of the above-mentioned effects. In addition, technical features that are not described as essential in this specification can be appropriately deleted. [Explanation of symbols]
