Cross-layer perceptual ARQ for H.264 video streaming over 802.11 wireless networks
TL;DR: A new cross-layer ARQ algorithm for video streaming over 802.11 wireless networks that combines application-level information about the perceptual and temporal importance of each packet into a single priority value, which drives packet selection at each retransmission opportunity.
Proceedings ArticleDOI
Performance Evaluation of H. 264 Video Streaming over Inter-Vehicular 802.11 Ad Hoc Networks
TL;DR: Evaluated video streaming in inter-vehicular environments using the 802.11 ad hoc network protocol determines the best packetization policies for the two scenarios, showing that large packets lead to better performance in the highway scenario and vice versa.
Journal ArticleDOI
Cloud Gaming with Foveated Video Encoding
Gazi Illahi,Thomas van Gemert,Matti Siekkinen,Enrico Masala,Antti Oulasvirta,Antti Ylä-Jääski +5 more
TL;DR: A cloud gaming FVE prototype that is game-agnostic and requires no modifications to the underlying game engine is provided and results suggest that it is possible to find a “sweet spot” for the encoding parameters so the users hardly notice the presence of foveated encoding but at the same time the scheme yields most of the achievable bandwidth savings.
Proceedings ArticleDOI
Traffic Prioritization of H.264/SVC Video over 802.11e Ad Hoc Wireless Networks
TL;DR: Results show that the H.264/SVC codec particularly benefits from the proposed algorithm, which enables a graceful video quality degradation in congested network conditions, as well as PSNR gains up to 2 dB with respect to the H264/AVC codec using the same amount of network resources.
Proceedings ArticleDOI
Analysis-by-synthesis distortion computation for rate-distortion optimized multimedia streaming
Enrico Masala,J.C. De Martin +1 more
TL;DR: The proposed analysis-by-synthesis technique computes the distortion that would be caused by the loss of each single packet, including the effects of error propagation and receiver-side error concealment, to evaluate the perceptual importance of multimedia packets for rate-distortion optimized streaming.
