Title (EN) LI-FI COMMUNICATIONS FOR SELECTING CONTENT FOR DISTRIBUTION ACROSS A SEQUENCE OF DISPLAYS ALONG A VEHICLE PATHWAY
(FR) COMMUNICATIONS LI-FI POUR SÉLECTIONNER DU CONTENU EN VUE D'UNE DISTRIBUTION SUR UNE SUCCESSION D'AFFICHAGES LE LONG D'UN PARCOURS DE VÉHICULE
Abstract:
(EN) A content distribution node that distributes content to display devices which are arranged in a spaced apart sequence along a pathway of vehicles for display to passengers. The content distribution node receives from a mobile gateway node of a vehicle, through a Light Fidelity signal receiver circuit, a profile message containing profile information related to the vehicle. The content distribution node selects, from among content files available in a content repository, a set of video frames for distribution to the display devices based on the profile information. The content distribution node distributes different video frames among the set of video frames to different ones of the display devices with timing of the distribution that allows the video frames among the set to be displayed on respective ones of the display devices in the sequence before arrival of the vehicle within a field-of-view of at least one of the display devices.
(FR) L'invention concerne un nœud de distribution de contenu qui distribue du contenu à des dispositifs d'affichage qui sont disposés en une succession espacée le long d'un parcours de véhicules en vue d'une présentation à des passagers. Le nœud de distribution de contenu reçoit en provenance d'un nœud de passerelle mobile d'un véhicule, via un circuit récepteur de signal Li-Fi, un message de profil contenant des informations de profil liées au véhicule. Le nœud de distribution de contenu sélectionne, parmi des fichiers de contenu disponibles dans un référentiel de contenu, un ensemble de trames vidéo en vue de leur distribution aux dispositifs d'affichage selon les informations de profil. Le nœud de distribution de contenu distribue différentes trames vidéo parmi l'ensemble de trames vidéo à des dispositifs différents parmi les dispositifs d'affichage avec une chronologie de distribution permettant aux trames vidéo de l'ensemble d'être affichées sur des dispositifs respectifs parmi les dispositifs d'affichage dans la succession avant l'arrivée du véhicule dans un champ de vision d'au moins un des dispositifs d'affichage.
