Control framework and services scenarios of provisioning n-screen services in interactive digital signage

In this article, we present the control framework and services scenarios of provisioning N-Screen services in interactive digital signage. Digital Signage provides a variety of high-resolution content and information displays at different public places and events. Provisioning N-Screen services in interactive digital signage enables the service providers to provide content to heterogeneous devices, allows the end user to share content from the digital signage to the user N-Screen devices and vice versa at different locations and times. We provide N-Screen services in interactive digital signage by adapting the content user interface according to user's N-Screen device size, layout, localized content adaptation, synchronization and session continuity over heterogeneous devices. We introduce the N-Screen User Interface Management Server (NUIMS), Digital Signage Management Server (DSMS), and Localized Content and Session Management Agent (LCSMA) to support N-Screen services. Furthermore, the N-Screen Devices Repository (NDR) at the DSMS keeps the users N-Screen devices static profile in order to share the content across all of their devices, and the LCSMA maintains the dynamic profile to synchronize content on heterogeneous devices. In addition, we suggest procedures, protocols and service scenarios to share the content of the digital signage to user’s N-Screen devices, methods to synchronize the content display over heterogeneous signage displays with content session continuity and to share with other users using the user information server.
