Abstract EN
A novel cross-layer optimized video adaptation driven by perceptual semantics ispresented.
The design target is streamed live video to enhance situational awareness in challenging communications conditions.
Conventional solutions for recreational applications are inadequate and novel quality of experience (QoE) framework is proposed which allows fully controlled adaptation and enables perceptual semantic feedback.
The framework relies on temporal/spatial abstraction for video applications serving beyond recreational purposes.
An underlying cross-layer optimization technique takes into account feedback on network congestion (time) and erasures (space) to best distribute available (scarce) bandwidth.
Systematic random linear network coding (SRNC) adds reliability while preserving perceptual semantics.
Objective metrics of the perceptual features in QoE show homogeneous high performance when using the proposed scheme.
Finally, the proposed scheme is in line with content-aware trends, by complying with information-centric-networking philosophy and architecture.
