Research Areas• Multimedia Communication and Adaptation

– Adaptive video streaming, protocols, (in-network) adaptation– Ambient, personalized, user-centric multimedia (UMA/UME)

• Distributed MMC Infrastructure and QoS Provisioning – Metadata streaming, compressed processing – Distributed adaptation, cross-layer QoS optimizations/mappings– Prototype Adaptive Multimedia Tools and Services

• MPEG Standardization– MPEG Extensible Middleware (MXM)– MPEG-V Sensory Information– MPEG Dynamic Adaptive Streaming over HTTP (DASH) and Modern

Media Transport (MMT)

Selected Projects (1)In-network Video Adaptation• Goal: on-the-fly video adaptation on network

devices, e.g., (wireless) router• Approach: utilize scalable video coding (ext. of

AVC/H.264); adaptation in spatial, temporal, and SNR domain ➪ ALICANTE (EU FP7 Integrated Project)

Selected Projects (2)P2P-Next (EU FP7 Integrated Project)• Goal: next generation peer-to-peer networks,

specifically, streaming of scalable media formats in P2P mode

• Approach: research, prototyping, and trials in Klagenfurt & around the world

Selected Projects (3)Internet Video Streaming• Goal: efficient multimedia streaming over

HTTP/TCP• Approach: research & development, prototyping,

measurements, and standardization

Selected Projects (4)What comes after 3D Video? Sensory Effects➪• Goal: improving the Quality of Experience

through sensory effects• Approach: annotate videos with add’l effects

(wind, light, explosion, etc.) which are rendered on specific devices (fan, vibration chair, etc.), subjective tests, QoE models ➪ Lange Nacht der Forschung, 5.11.2010
