Perceptual optimized adaptive HTTP streaming

2017 IEEE Visual Communications and Image Processing (VCIP), 2017
The paper presents a perceptual optimized adaptive HTTP streaming scheme to improve the quality of experience (QoE). In addition to barely controlling the bandwidth and buffer size in existing works, this paper integrates the video saliency based adaptation to improve the perceptual quality for end users. Resources (e.g., buffer) are well managed using

SVC-Based HTTP Adaptive Streaming

Bell Labs Technical Journal, 2012
HTTP adaptive streaming (HAS) is rapidly evolving into a key video delivery technology, supported by implementations from Microsoft, Apple, and Adobe, and actively pursued by standardization organizations. Using segments in multiple video qualities, distributed via an already available Hypertext Transfer Protocol (HTTP) delivery infrastructure, a HAS ...

On Adaptive HTTP Streaming to Mobile Devices

2013 20th International Packet Video Workshop, 2013
Adaptive Streaming over HTTP is a new video streaming technique that starts to boom in recent years. Meanwhile, mobile devices are quickly becoming the main platform for streaming services. Adaptive streaming to mobile devices faces additional challenges of high TCP throughput variability and limited battery supply.

QoE-optimal rate adaptation for HTTP adaptive streaming

2016 IEEE/CIC International Conference on Communications in China (ICCC), 2016
HTTP Adaptive Streaming(HAS) has become widely deployed in multimedia services for its ability for providing the best Quality of Experience(QoE) for viewers with limited resource, especially in fluctuating wireless networkings. With its client-driven rate adaptation mechanism, HAS is able to adapt to fluctuating network condition and various terminals ...

Request adaptation for adaptive streaming over HTTP/2

2016 IEEE International Conference on Consumer Electronics (ICCE), 2016
In this paper, we propose a client-based adaptation method for Adaptive Streaming over HTTP/2 leveraging the server push feature. A cost function that takes into account both the number of pushed segments and the playout buffer level is defined. Experiment results show that the proposed method can improve the tradeoff between the number of requests and

Dynamic Adaptive Streaming over HTTP/2.0

2013 IEEE International Conference on Multimedia and Expo (ICME), 2013
MPEG Dynamic Adaptive Streaming over HTTP (DASH) is a new streaming standard that has been recently ratified as an international standard (IS). In comparison to other streaming systems, e.g., HTTP progressive download, DASH is able to handle varying bandwidth conditions providing smooth streaming.

Traffic model for HTTP-based adaptive streaming

2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2017
The amount of video traffic on the Internet has seen a tremendous increase over the past few years. In 2020, it is predicted to account for 85% of the total Internet consumer traffic. Due to this dominant role, streaming traffic has to be considered by workload models used to evaluate the performance of networking systems.

A Cumulative Quality Model for HTTP Adaptive Streaming

2018 Tenth International Conference on Quality of Multimedia Experience (QoMEX), 2018
The quality of adaptive streaming may fluctuate strongly during a session. Therefore, a challenge is how to evaluate the quality of a session over time. In this study, a cumulative quality model is proposed for HTTP adaptive streaming. The model is based on the concept of a sliding window of video segments over a session.

Bandwidth estimation and rate adaptation in HTTP streaming

2012 International Conference on Computing, Networking and Communications (ICNC), 2012
HTTP Streaming is one type of video streaming technology, delivering multimedia data using HTTP/TCP. Due to the strict boundaries between layers of the OSI communication model, HTTP Streaming client at the Application Layer can only see the bandwidth that TCP at the Transport Layer supplies.
