#IBC2024 BBC, AWS AND NRK TO PRESENT TECHNICAL PAPER FINDINGS
The Technical Papers Programme continues in Conference Room 2 today with provenance, streaming and XR on the agenda. Sessions begin with ‘Provenance – What can we trust’ at 11:00. This will see John Simmons, Media Platform Architect, Verance, and Judy Parnall, Head of Standards & Industry, BBC R&D, present two papers. One provides an extraordinary walk through of the recently standardised Coalition for Content Provenance and Authenticity (C2PA) security and trust system. The second reports on trials undertaken by the BBC and the Media Cluster, Norway to implement C2PA, including how best to communicate that provenance information to the viewer.
At 12:30 Andrew Murphy, Lead Research Engineer, BBC, and Girish Nair, Senior Media Specialist Solution Architect, AWS India, will look at streaming from both
ends; at one end AWS shares its engineering insights and experiences in facilitating streaming at “mega-concurrency scale”. At the other end the BBC has been studying the actual day-to-day user experience of mobile services while on the go, using its BBC Sounds app – correlating network/ radio properties and CDN logs to determine the concept of a service coverage area.
The day ends with an extended session looking at ‘XR – Advances in capturing, rendering and delivering’. Running from 15:00- 17:00 and consisting of four papers, the session begins with an outstanding paper on the emerging volumetric video technology, Neural Radiance Fields (NeRFs). The second paper presents results of an ultra-low bitrate 3D conferencing system, built using pre-trained NeRF models for high-fidelity 3D head reconstruction and real-time rendering. The third paper seeks
a universally acceptable standard for representing volumetric video. Built off glTF (Graphics Library Transmission Format), the authors will present results of both effective file playback and its suitability for streaming. Finally, the last paper of the day
rethinks capture with a camera system that can be adaptively adjusted across its field, to simultaneously capture regions of high-dynamic range (with longer exposure) and high-motion (with higher frame-rate). A working proof-of-concept will be presented and discussed in detail. This session is further supported by a BBC paper exploring how to incorporate a live music event into a virtual environment. Aljosa Smolic, Professor at Hochschule Luzern; Joshua Maraval, Research Engineer, B-Com; and Kodai Kikuchi, Research engineer, NHK, will be presenting.
