Objective and subjective QoE evaluation for adaptive point cloud streaming
Van Der Hooft, J.; Vega, M. T.; Timmerer, C.; Beğen, Ali Cengiz; De Turck, F.; Schatz, R. (IEEE, 2020-05)Volumetric media has the potential to provide the six degrees of freedom (6DoF) required by truly immersive media. However, achieving 6DoF requires ultra-high bandwidth transmissions, which real-world wide area networks ... -
Optimum encoding approaches on video resolution changes: a comparative study
Asan, A.; Mkwawa, I.-H.; Sun, L.; Robitza, W.; Beğen, Ali Cengiz (IEEE, 2018)Video resolution changes in an HTTP adaptive streaming session may negatively affect the viewer's quality of experience. Our goal is, through encoding, to make such resolution changes less noticeable for the viewers. This ... -
Performance analysis of ACTE: A bandwidth prediction method for low-latency chunked streaming
Bentaleb, A.; Timmerer, C.; Beğen, Ali Cengiz; Zimmermann, R. (Association for Computing Machinery, Inc, 2020-07)HTTP adaptive streaming with chunked transfer encoding can offer low-latency streaming without sacrificing the coding efficiency. This allows media segments to be delivered while still being packaged. However, conventional ... -
QoE-aware bandwidth broker for HTTP adaptive streaming flows in an SDN-enabled HFC network
Bentaleb, A.; Beğen, Ali Cengiz; Zimmermann, R. (IEEE, 2018-06)This paper proposes a software defined networking based bandwidth broker solution for improving viewer experience for any type of content delivered to any type of consumer device using HTTP adaptive streaming (HAS) in a ... -
Quality upshifting with auxiliary I-Frame splicing

(IEEE, 2023)This paper introduces the Auxiliary I-Frame Splicing method to reduce bandwidth waste in adaptive streaming. This method involves fetching a high-quality I-frame and splicing it into the already downloaded low-quality ... -
Quickly starting media streams using QUIC
Arısu, Şevket; Beğen, Ali Cengiz (Association for Computing Machinery, Inc, 2018-06-12)Originally proposed by Google, QUIC is a low-latency transport protocol currently being developed and specified in the IETF. QUIC's low-latency, improved congestion control, multiplexing features are promising and may help ... -
Rate-adaptive streaming of 360-degree videos with head-motion-aware viewport margins
Akçay, Mehmet Necmettin; Kara, Burak; Beğen, Ali Cengiz; Ahsan, S.; Curcio, I. D. D.; Aksu, E. (IEEE, 2022)Efficient use of available bandwidth is vital when streaming 360-degree videos as users rarely have enough bandwidth for a pleasant experience. A promising solution is the combination of viewport-dependent streaming using ... -
Redundant encoding and packaging for segmented live media
Mekuria, R.; Raad, M.; Beğen, Ali Cengiz (ACM, 2023-06-16)We present the MPEG standardization activity on redundant encoding and packaging for live segmented media. The standardization includes profiling the Dynamic Adaptive Streaming over HTTP (DASH) Media Presentation Description ... -
