Bandwidth prediction in low-latency chunked streaming
Bentaleb, A.; Timmerer, C.; Beğen, Ali Cengiz; Zimmermann, R. (The ACM Digital Library, 2019-06)HTTP adaptive streaming with chunked transfer encoding can be used to offer low-latency streaming without sacrificing the coding efficiency. While this allows a media segment to be generated and delivered at the same time, ... -
Bandwidth prediction in low-latency media transport
Bentaleb, A.; Akçay, Mehmet Necmettin; Lim, M.; Beğen, Ali Cengiz; Zimmermann, R. (ACM, 2023-06-16)Designing a robust bandwidth prediction algorithm for low-latency media transport that can quickly adapt to varying network conditions is challenging. In this paper, we present the working principles of a hybrid bandwidth ... -
The benefits of server hinting when DASHing or HLSing
Lim, M.; Akçay, Mehmet Necmettin; Bentaleb, A.; Beğen, Ali Cengiz; Zimmermann, R. (ACM, 2022-03-17)Streaming clients almost always compete for the available bandwidth and server capacity. Not every client's playback buffer conditions will be the same, though, nor should be the priority with which the server processes ... -
BoB: Bandwidth prediction for real-time communications using heuristic and reinforcement learning
Bentaleb, A.; Akçay, Mehmet Necmettin; Lim, M.; Beğen, Ali Cengiz; Zimmermann, R. (IEEE, 2023)Bandwidth prediction is critical in any Real-time Communication (RTC) service or application. This component decides how much media data can be sent in real time. Subsequently, the video and audio encoder dynamically adapts ... -
Catching the moment with LoL + in twitch-like low-latency live streaming platforms
Bentaleb, A.; Akçay, Mehmet Necmettin; Lim, M.; Beğen, Ali Cengiz; Zimmermann, R. (IEEE, 2022)Our earlier Low-on-Latency (dubbed as LoL) solution offered an accurate bandwidth prediction and rate adaptation algorithm tailored for live streaming applications that targeted an end-to-end latency of up to two seconds. ... -
Common media client data (CMCD): Initial findings
Bentaleb, A.; Lim, M.; Akçay, Mehmet Necmettin; Beğen, Ali Cengiz; Zimmermann, R. (Association for Computing Machinery, Inc, 2021-07-16)In September 2020, the Consumer Technology Association (CTA) published the CTA-5004: Common Media Client Data (CMCD) specification. Using this specification, a media client can convey certain information to the content ... -
Data-driven bandwidth prediction models and automated model selection for low latency
Bentaleb, A.; Beğen, Ali Cengiz; Harous, S.; Zimmermann, R. (IEEE, 2021)Today's HTTP adaptive streaming solutions use a variety of algorithms to measure the available network bandwidth and predict its future values. Bandwidth prediction, which is already a difficult task, must be more accurate ... -
A distributed approach for bitrate selection in HTTP adaptive streaming
Bentaleb, A.; Beğen, Ali Cengiz; Harous, S.; Zimmermann, R. (ACM, 2018)Past research has shown that concurrent HTTP adaptive streaming (HAS) players behave selfishly and the resulting competition for shared resources leads to underutilization or oversubscription of the network, presentation ... -
Foreword
Beğen, Ali Cengiz; Timmerer, C.; Zimmermann, R.; Schierl, T. (Association for Computing Machinery, Inc, 2018-06-12)N/A -
Game of streaming players: Is consensus viable or an illusion?
Bentaleb, A.; Beğen, Ali Cengiz; Harous, S.; Zimmermann, R. (Association for Computing Machinery, Inc, 2019-08)The dramatic growth of HTTP adaptive streaming (HAS) traffic represents a practical challenge for service providers in satisfying the demand from their customers. Achieving this in a network where multiple players share ... -
Game theory based bitrate adaptation for Dash.Js reference player
Bentaleb, A.; Beğen, Ali Cengiz; Zimmermann, R. (IEEE, 2018-11-28)Most existing DASH adaptive bitrate (ABR) schemes are designed to behave in their own self-interest and do not perform consistently in all network environments. In this work, we provide a practical implementation, materials ... -
Meta reinforcement learning for rate adaptation
Bentaleb, A.; Lim, M.; Akçay, Mehmet Necmettin; Beğen, Ali Cengiz; Zimmermann, R. (IEEE, 2023)Adaptive bitrate (ABR) schemes enable streaming clients to adapt to time-varying network/device conditions to achieve a stall-free viewing experience. Most ABR schemes use manually tuned heuristics or learning-based methods. ... -
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 ... -

Beğen, Ali Cengiz; Bentaleb, A.; Silhavy, D.; Pham, S.; Zimmermann, R.; Law, W. (IEEE, 2021-11-01)Streaming media has truly become one of the most popular applications on the Internet. Viewers are spoiled for choice, and content providers compete to provide the best viewer experience. Traditionally, it has been challenging ... -
SDNDASH: Improving QoE of HTTP Adaptive Streaming Using Software Defined Networking
Bentaleb, A.; Beğen, Ali Cengiz; Zimmermann, R. (ACM, 2016)HTTP adaptive streaming (HAS) is being adopted with increasing frequency and becoming the de-facto standard for video streaming. However, the client-driven, on-off adaptation behavior of HAS results in uneven bandwidth ... -
