Energy-Aware HDR Content End-to-End VVC Encoding

The proposed demonstration combines several commercially viable state-of-the-art technologies to achieve significant energy reduction while delivering HDR video without compromising QoE. The components of the demo are: (i) The demo is based our solution on VVC, the most efficient, highest quality video codec available today. (ii) We leverage Advanced HDR by Technicolor, a solution that uniquely can deliver HDR and SDR video using a single stream. (iii) We introduce a solution for dynamically adjusting peak brightness of displays via display adaptation controlled through the network using dynamic metadata encapsulated in MPEG SEI messages. This solution has been tested and shows a capability of reducing power by 10% or more without any subjective quality loss, and far more with minimal subjective impact. (iv) While we demonstrate a streaming (unicast) scenario in our live demo, our system is also capable of working in a dynamic unicast/multicast environment based on DVB transmission standards. (v) The entire demonstration is resulting from an industrial collaboration and is based on ready to market technologies and prototypes.
