Caching in HTTP Adaptive Streaming

Proceedings of Network and Operating System Support on Digital Audio and Video Workshop, 2014
Video streaming is a major source of Internet traffic today and usage continues to grow at a rapid rate. To cope with this new and massive source of traffic, ISPs use methods such as caching to reduce the amount of traffic traversing their networks and serve customers better.

Parallel Adaptive HTTP Media Streaming

2011 Proceedings of 20th International Conference on Computer Communications and Networks (ICCCN), 2011
Recent advances in adaptive HTTP streaming of 3GPP have paved the way to the development of media streaming over HTTP. The traditional HTTP streaming relies on a series of request segments and receive segments sequentially. In the current Internet media segments can be delivered through distributed networks.

Adaptive video streaming over HTTP

Proceedings of the 2014 ACM Southeast Regional Conference, 2014
A new video streaming scheme is proposed and its prototype is implemented in this paper. The scheme is designed for providing an enhanced QoS for a client using a mobile device. With the scheme, the client considers various important network factors to decide its bit rate. It then sends feedback whenever its current bit rate must be changed. Based upon

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 ...

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 ...

EADAS: Edge Assisted Adaptation Scheme for HTTP Adaptive Streaming

2021 IEEE 46th Conference on Local Computer Networks (LCN), 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.

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

Buffer-based bitrate adaptation for adaptive HTTP streaming

2013 International Conference on Advanced Technologies for Communications (ATC 2013), 2013
Live and on-demand video streaming has recently contributed a significant part of the Internet traffic. In order to guarantee the best possible user experience, multimedia service is required to support large fluctuations in different network conditions. One of the cost effective means for multimedia delivery nowadays is HTTP streaming.
