A Perceptual Optimization Approach to Adaptive HTTP Streaming

2018
This paper presents a perceptual optimization scheme for the adaptive HTTP streaming services. It is well-known that the content features have deep influence on the user’s quality of experience (QoE). However, most of the existing algorithms only consider bandwidth and buffer in quality control. This paper integrates the video-saliency-based adaptation

Dynamic adaptive streaming over HTTP dataset

Proceedings of the 3rd Multimedia Systems Conference, 2012
The delivery of audio-visual content over the Hypertext Transfer Protocol (HTTP) got lot of attention in recent years and with dynamic adaptive streaming over HTTP (DASH) a standard is now available. Many papers cover this topic and present their research results, but unfortunately all of them use their own private dataset which -- in most cases -- is ...

Evaluation of adaptive streaming algorithms over HTTP

2013 IEEE Third International Conference on Consumer Electronics ¿ Berlin (ICCE-Berlin), 2013
In order to guarantee the best user experience throughout different network access technologies with dynamically varying network conditions, it is fundamental to adopt new technologies enabling a proper reception of the multimedia content. In this paper we implemented a prototype of streaming client, based on the MPEG DASH standard.

Towards Agile and Smooth Video Adaptation in HTTP Adaptive Streaming

IEEE/ACM Transactions on Networking, 2016
HTTP Adaptive Streaming (HAS) is widely deployed on the Internet for live and on-demand video streaming services. Video adaptation algorithms in the existing HAS systems are either too sluggish to respond to congestion level shifts or too sensitive to short-term network bandwidth variations. Both degrade user video experience.

Quality of Experience Driven Rate Adaptation for Adaptive HTTP Streaming

IEEE Transactions on Broadcasting, 2018
A quality of experience (QoE) driven rate adaptation approach is proposed in this paper for adaptive HTTP streaming which jointly considers both bandwidth savings and video quality adaptation into account for the rate adjustment, beneficial to both service providers and subscribers.

QoE Assessment of HTTP Adaptive Video Streaming

2015
Quality of Experience (QoE) is a crucial characteristic of any multimedia service and must be accounted for during the service development and planning stages. Nonetheless, given its subjective nature, it is extremely difficult to use analytical methods to estimate the average Mean Opinion Score (MOS).

A novel adaptive logic for dynamic adaptive streaming over HTTP

Journal of Visual Communication and Image Representation, 2017
Abstract In this paper, we propose an estimation method that estimates the throughput of upcoming video segments based on variations in the network throughput observed during the download of previous video segments. Then, we propose a rate-adaptive algorithm for Hypertext Transfer Protocol (HTTP) streaming.
