System Architecture

This document will include an overall system architecture building upon the high level model presented here, covering overall system design, functional specifications for each of the WP5 components and high level component interactions. This document will also capture key technical decisions on areas such as: • Device / service discovery (e.g. UPnP) • Choice of client application environment (e.g. HbbTV2.0) • Media Application Component technology (e.g. HTML/JS/CSS) • Approach to device and content synchronisation (likely building upon second screen sync technology such as UPnP Multiscreen, DIAL, DVB CSS etc.) • Orchestration & Authoring approach, including • Layout and composition model • Production presentation requirements vocabulary
