- a downlink radio interface for receiving broadcast digital content from a service platform
- a filtering unit for selecting at least one digital content among the digital contents received on the radio interface unit, according to an identifier of the access device
- a storage unit for storing said at least one selected digital content
- a management unit for selecting a first digital content if the storage unit stores a plurality of digital contents, for triggering the reading of said first digital content and for transmitting the first digital content selected on the digital screen via a transmission interface.
- the present invention provides for the broadcasting of digital content by a broadcast operator using at least one non-connected broadcast technology, such as DVB (Digital Video Broadcasting), DVB-T , DVB-H, etc.) or DAB (for Digital Audio Broadcasting), DAB +, DMB (for Digital Multimedia Broadcasting) or T-DMB, or ATSC, ISBT or 3GPP / LTE Simless standards eMBMs, which is out of step with prior art techniques that use point-to-point links in connected mode of telecommunication operators, expensive and uncertain as to the area covered.
- the aforementioned broadcasting technologies have much larger average coverage radii (about 30 km against 3 km for the connections in connected mode) and the surface cost of a coverage area is actually much lower.
- the invention thus makes it possible to reduce costs since it is no longer necessary to contract a subscription from a telecommunications operator for each of the digital screens and makes possible scale effects to significantly reduce the cost of dissemination for a set of digital screens.
- Access to the service platform is also less dependent on the coverage area of network operators, considering that the offer of a broadcasting operator is more attractive because it offers much larger coverage areas, including rural area.
- the same digital contents are thus broadcast by the service platform and are filtered by the access device, which makes it possible to maintain a differentiation in the displayed digital contents, while limiting costs.
- the invention makes it possible to decouple the reception mechanisms of the digital and reading contents.

- the identifier may be a unique identifier stored in the access device.
- a unique identifier in addition to the use of the location of the access device, makes it possible to personalize the contents displayed on the digital screens, even in cases in which a location signal (GPS for example) can not be picked up by the access device.
- a location signal GPS for example
- the use of a unique identifier makes it possible to keep the locations of the digital screens confidential, which is particularly advantageous when the organization in charge of the service platform is distinct from the organization in charge. a set of screens digital.
- the management unit may be able to delete a stored digital content when a storage capacity of the storage unit is insufficient to receive a new digital content selected by the filtering unit, or to replace one of the digital contents stored by a new digital content selected by the filter unit.
- the management of the stored digital contents is thus ensured by the access device.
- Digital content can thus be regularly updated without requiring significant storage capacity at the access device.
- the device may further comprise at least one sensor capable of detecting an event, and the management unit may be able to select and trigger the reading of the first digital content according to a event detected by the sensor.
- the digital contents displayed on a digital screen can thus be adapted dynamically to the environment of the digital screen.
- the downlink radio interface may further be adapted to receive a command from the service platform, the control comprising a digital content identifier and access device identifier data, and the filtering may be able to transmit the command to the management unit if the access device identifier data correspond to the identifier of the access device, and the first digital content may be the digital content corresponding to the access device identifier. digital content identifier of the order.
- the service platform dynamically manages the display of contents stored locally on the access devices. Indeed, little bandwidth is consumed by sending commands containing only identifiers.
- the display of content can thus be adapted to one-off events, which makes it possible to better target the audience of the digital screen.
- the command may furthermore comprise a reading instant, and the management unit may be able to trigger the reading of the first digital content at the time of reading the command.
- the service platform can thus anticipate the display of digital contents adapted to a future event.
- the transmission interface may be adapted to transmit first digital contents respectively to several digital screens.
- Such an embodiment makes it possible to minimize the costs by pooling the access device, without however preventing different digital contents being displayed on the digital screens connected to the access device.
- the command may furthermore comprise a digital screen identifier
- the management unit may be able to transmit the first digital content corresponding to the digital content identifier of the command, to the digital screen corresponding to the numerical screen identifier of the command.
- the access device may further comprise an uplink radio interface unit for transmitting supervisory data or contextual data to the service platform.
- the access device may further comprise a decryption unit capable of decrypting the digital content selected by the filtering unit.
- the digital content broadcast by the service platform can thus be encrypted, which prevents interception and display by third-party devices.
- a second aspect of the invention relates to a digital content display system comprising an access device according to the first aspect of the invention and at least one digital display.
- a third aspect of the invention relates to a method of accessing a service platform for at least one digital screen, the method being implemented in an access device connected to said at least one digital screen, and comprising the following steps : - receiving broadcast digital content from a service platform;
- a fourth aspect of the invention relates to a computer program comprising instructions for implementing the method according to the third aspect of the invention, when this program is executed by a processor.
