In recent years many developments have addressed the generic objective of delivering audiovisual content based on a single representation made available at the source, and where the network gets the ability to adapt the content on an end user basis. This chapter reviews the different aspects related to format-agnostic delivery. It proposes methods that try to combine the benefits of two approaches: scale to many users and spatial interaction at the highest picture quality available. The chapter focuses on a new functionality that enables a client device to interactively and efficiently access a portion of ultra-high definition panoramic encoded content. It presents examples showing how the tiling approach gives some lever to optimise the overall coding performance of the panorama, as well as the selection of tiles to be transmitted to an interactive client. Finally, the chapter addresses two approaches to develop a transport mechanism, each targeting different deployment scenarios. © 2014 John Wiley & Sons, Ltd. All rights reserved.
