Title
(EN) SELECTIVELY DISTRIBUTING UPDATES OF CHANGING IMAGES TO CLIENT DEVICES
(FR) DISTRIBUTION SÉLECTIVE DE MISES À JOUR D'IMAGES CHANGEANTES À DES DISPOSITIFS CLIENTS
Abstract
(EN)
A network server for sharing images with mobile electronic devices having one or more processors, and image sharing client application, and an image distribution application. The image sharing client application is to be executed on one or more of the processors to receive an update to an image being shared over a network with mobile electronic devices that each have their own current zoom level and their own currently visible area of the image. The image distribution application is to be executed on one or more of the processors to keep a record of the current zoom level and currently visible area for each of the plurality of mobile electronic devices and to selectively send image updates to the plurality of mobile electronic devices based on the current zoom level and currently viewable area of the mobile electronic devices.

La présente invention concerne un serveur de réseau pour partager des images avec des appareils électroniques mobiles ayant un ou plusieurs processeurs, une application client de partage d'images et une application de distribution d'image. L'application client de partage d'images doit être exécutée sur un ou plusieurs processeurs pour recevoir une mise à jour relative à une image qui est partagée sur un réseau avec des appareils électroniques mobiles qui ont chacun leur propre niveau de zoom actuel et leur propre zone actuellement visible de l'image. L'application de distribution d'image doit être exécutée sur un ou plusieurs des processeurs pour garder une trace du niveau de zoom actuel et de la zone actuellement visible pour chacun des différents appareils électroniques mobiles et pour envoyer de manière sélective des mises à jour d'image à la pluralité d'appareils électroniques mobiles sur la base du niveau de zoom actuel et de la zone actuellement visible des appareils électroniques mobiles.
