This paper presents the concept of the Media State Vector (MSV), an implementation of uni-dimensional motion in real time. The MSV is intended as a general representation of media navigation and a basis for synchronization of multi-device media presentations. The MSV is motivated by the idea that media navigation can be decoupled from media content and visual presentation, and shared across a network. Implementation of the MSV concept for the Web allows us to construct navigable, synchronized, multi-device, multimedia presentations, spanning computers across the Internet. In particular, media presentations may be hosted by regular Web browsers on a range of devices, including smart phones, pads, laptops and smart TVs. Our proof of concept implementation bases its synchronization accuracy on primitive, centralized, ad-hoc, application-level clock synchronization. Still, inter-client synchronization error of about 33 ms is demonstrated between three screens in London (UK), synchronized via a server in Tromsø (Norway).
