DESCRIPTION MORE

DETALLLEE

In the different figures, designate identical elements or the same similar references.

FIG. 1 shows a network 1 for broadcasting digital content comprising a plurality of devices

display digital 2, including each a screen digital 3. The content digital in question can

include videos and still images.

This digital content can be transmitted to the digital display devices 2 from at least one remote server 4, by any wide area network (“WAN”), in particular by the internet network 5. The wide area network may possibly include one or more radio links 6 (e.g. LTE standard or other) to all or part of the digital display devices 2.

The digital display devices 2 can be arranged in particular in public places, that is to say all places accessible to the public such as public thoroughfare, stations, airports, shopping centers, etc. They can be spread over a wide area, for example one or more continents.

As shown in FIG. 2, each digital display device 2 comprises a screen control computer 7 which may in particular include a central unit 8 (UC1) such as a processor controlling the digital screen 3, a communication interface 9 (MODEM) adapted to communicate with the wide area network 5, 6, and a mass memory 10 (M) for storing digital content.

The central unit 8 is adapted to communicate with the server 4 to receive digital contents to be displayed and to store them in the memory 10.

In particular, the memory 10 contains at least one list of digital contents (“playlist”) to be displayed on the screen 3 and the central unit 8 is programmed to automatically display the digital contents of this list by the digital screen 3 (the list of digital contents can in particular be played in loop on the digital screen 3). The list of digital contents can be received already made up of the server 4, or else can be determined by the central processing unit 8 according in particular to predefined criteria, starting from the whole of the digital contents received from the server 4.

More specifically, the central unit 8 executes screen control software which is adapted to communicate with the server 4, possibly determines the list of digital contents to be displayed by the digital screen 3 and controls the digital screen 3.

Furthermore, the digital display device 2 comprises at least one interface adapted to interact with a local environment located near the digital screen 3.

This interface can for example include at least one radio communication interface 13, 14 adapted to communicate with a mobile terminal 16 (in particular “smartphone”, “smartpad” or the like) used by a member of the public located near the digital display device 2.

This radio communication interface can be chosen in particular from a Wi-Fi interface 13 (which can also serve as a free Wi-Fi access point for members of the public), an NFC interface 14, a long-distance RFID interface, a Bluetooth interface and an http interface ("WebSocket").

The interface can also include a detector 15 adapted to detect a presence and / or a movement and / or behavior at least one person public and / or d 'a vehicle (in which is or can himself find an user ) · This detector can understand a camera, through example a suitable camera to make analysis Image and detect at less a characteristic of at least

a member of the public (in particular gender (male / female), average age, expression, orientation of the face, position of the hand or of an object visible from the camera, a camera adapted to measure a number and / or a flow of people , Or other.

The interface can also include an input interface that can be activated by a member of the public by physical contact on the display device 2 (for example a button, or the digital screen 3 if it is tactile), or an interface contactless input such as time of flight sensor (including LIDAR or other), infrared sensor, or other.

The interface 13, 14, 15 is connected to an electronic central unit 12 (UC2) such as a processor, which is itself in a local network with the central unit 8 of the screen control computer 7 The central units 8, 12 can be linked together by a wired link (Ethernet cable, USB cable or other), or by a wireless link.

The central processing unit 12 and the user interface (s)

13-15 can form a set or kit 11. It is thus easy to add the kit 11 to a preexisting digital display device 2.

The kit 11 may possibly be in the form of a box which is simply connected to the electrical supply and to the central unit 8 as explained above.

When an interface

13-15 interacts with a member of the public (detection of one or more persons or vehicles or their movement, or detection of characteristics of persons of the public, or detection of an actuation of an input interface of the device digital display 2, or radio communication between

The interface (in particular 13, and a mobile terminal of a member of the public),

The central unit 12 transmits information relating to screen control interactions between the interface 13-15 and said person of the public.

This information can be used to control the control computer the screen control computer for, depending on a screen interaction 7. In particular, can be programmed between the interface and at least one member of the public, modify the digital content displayed by the digital screen 3.

More particularly, the screen control software can be adapted to receive display instructions from the server 4. These display instructions can be received from the server 4 by a software port, in particular a determined TCP port (for example TCP port 2324). Advantageously, the same software port is used to communicate the screen control software with the central unit 12. This communication can be done for example in XML language.

For example, the central unit 12 can be adapted to transmit to the screen control software, predefined orders making it possible to at least partially modify the list of contents to be displayed, or to display specific digital content which may be either a digital content stored in memory 10, either content available on the internet, or other.

In this way, the screen display can be modified according to interactions between the interface and members of the public, which makes it possible, for example, to carry out dynamic advertising campaigns.

By way of example, if a member of the public approaches their mobile terminal 16 provided with NFC functions during the display of a certain predetermined advertisement on the digital screen 3, the central unit 12 of the kit can for example send by the NFC interface 14, on the mobile terminal 16, a link to a website allowing to learn about the product concerned and / or to buy it, the central unit 12 of the kit can also send a voucher or the like on the mobile terminal 16, and said central unit 12 can display on the digital screen 3 (via the aforementioned software port), a specific page in connection with the interaction which took place with the mobile terminal (for example a page congratulating the public on having received a voucher).

According to another example, as illustrated in FIG. 3, if a member of the public U approaches his mobile terminal 16 provided with Wi-Fi functions under certain predefined conditions, the central unit 12 causes the operation of the screen control software to change to no longer display a list of posters running in a loop, but for example an internet page, in particular an internet game. In this case, the user's mobile terminal 16 can be used as an input interface to control actions in the game (in particular by the touch screen of the mobile terminal and / or by detection of movements of the mobile terminal by means of accelerometers integrated into this mobile terminal 16). It may thus be possible to play, alone or with others, on the digital display device 2 for a certain predefined time.

As a variant, instead of having the members of the public U play, it is possible to authorize them to modify the display of the digital display device 2, for example to type text and have it displayed, or to display emoticons or other predetermined objects.

In all cases, the interaction between the display and the members of the public is local (user U is within sight of screen 3), therefore very reactive, regardless of the bandwidth between the device. digital display 2 and server 4.

More generally, the aforementioned interface could interact with the local environment of the digital display device 2, which may include an interaction with a user U close to the display device or with other aspects of the local environment.

For example, the sensor 15 could, instead of being a presence or movement detector, comprise for example an air pollution sensor and / or an ultraviolet sunshine level sensor and / or a rain sensor and / or a temperature sensor, or the like (or the device could comprise a sensor 15 which may be a presence or movement detector, and an environmental sensor 15 such as those mentioned above). In this particular example, the predetermined interaction which triggers the modification of the digital content displayed, can in particular be the detection of certain ambient conditions, in particular level of air pollution and / or level of ultraviolet sunshine and / or noise and / or odors and / or rain detection and / or temperature level detection.
