Timely and Accurate Bitrate Switching in HTTP Adaptive Streaming With Date-Driven I-Frame Prediction

IEEE transactions on multimedia, 2023
In today's Internet, bandwidth dynamics are inevitable, and hence, the bitrate for live streaming applications should also be dynamically adjusted. However, in existing HTTP-based adaptive streaming (HAS), bitrate switching can only be performed at ...

Adaptation algorithm for adaptive streaming over HTTP

2012 19th International Packet Video Workshop (PV), 2012
Internet video makes up a significant part of the Internet traffic and its fraction is constantly growing. In order to guarantee best user experience throughout different network access technologies with dynamically varying network conditions, it is fundamental to adopt technologies enabling a proper delivery of the media content.

Toward HTTP adaptive streaming

Proceedings of the 11th ACM Multimedia Systems Conference, 2020
With increasing popularity of smart devices and better bandwidth allocations for end users, online video streaming demand is rising. As an Over-the-Top (OTT) service provider, we implemented HTTP Adaptive Streaming (HAS) technology to address this concerns by considering limitations of legacy streaming protocols.

EADAS: Edge Assisted Adaptation Scheme for HTTP Adaptive Streaming

IEEE Conference on Local Computer Networks, 2021
Mobile networks equipped with edge computing nodes enable access to information that can be leveraged to assist client-based adaptive bitrate (ABR) algorithms in making better adaptation decisions to improve both Quality of Experience (QoE) and fairness.

Segment duration for rate adaptation of adaptive HTTP streaming

2011 IEEE International Conference on Multimedia and Expo, 2011
Recently, 3GPP packet-switched streaming (PSS) specified adaptive HTTP streaming (AHS). The client requests series of media segments and adapt the bitrates of segment to varying network resources. The current state-of-the-art rate adaptation of AHS estimates the end-to-end network capacity using the previous segment reception such as segment fetching ...

CoS enforcement for HTTP adaptive streaming

2012 IEEE Globecom Workshops, 2012
As the HTTP-based segmented video delivery paradigm continues to grow in popularity, the ability to enforce differentiated classes of service (CoS) across large numbers of clients becomes increasingly important. Differentiated services are an important monetization technique for content service providers.
