Adaptive Video Streaming Adapting video quality to radio links with different characteristics

by William Eklöf
"... During the last decade, the data rates provided by mobile networks have improved to the point that it is now feasible to provide richer services, such as streaming multimedia, to mobile users. However, due to factors such as radio interference and cell load, the throughput available to a client vari ..."

at different bit rates, thereby allowing the media’s bit rate (and quality) to be modified to fit the client’s bandwidth. This is referred to as adaptive streaming. The aim of this thesis is to devise an algorithm to find the media quality most suitable for a specific client, focusing on how to detect

bitrate video streaming has become a popular alternative to its Real-Time Transport Protocol

by Chao Chen, Student Member, Lark Kwon Choi, Student Member, Gustavo De Veciana, Constantine Caramanis, Robert W. Heath, Alan C. Bovik
"... Newly developed HTTP-based video streaming technologies enable flexible rate-adaptation under varying channel conditions. Accurately predicting the users ’ Quality of Experience (QoE) for rate-adaptive HTTP video streams is thus critical to achieve efficiency. An important aspect of understanding an ..."

Joint-family: Enabling adaptive bitrate streaming in p2p video-on-demand

by Kyung-Wook Hwang , Vijay Gopalakrishnan , Rittwik Jana , Seungjoon Lee , Vishal Misra , K K Ramakrishnan , Dan Rubenstein - In ICNP , 2013
"... Abstract-We propose Joint-Family, a protocol that combines peer-to-peer (P2P) and adaptive bitrate (ABR) streaming for video-on-demand (VoD). While P2P for VoD and ABR have been proposed previously, they have not been studied together because they attempt to tackle problems with seemingly orthogona ..."

Video stream quality impacts viewer behavior: Inferring causality using quasi-experimental designs

by S Shunmuga Krishnan , Ramesh K Sitaraman - in Proc. Internet Measurement Conf , 2012
"... ABSTRACT The distribution of videos over the Internet is drastically transforming how media is consumed and monetized. Content providers, such as media outlets and video subscription services, would like to ensure that their videos do not fail, startup quickly, and play without interruptions. In re ..."

sciences. We study the impact of video stream quality on viewer behavior in a scientific data-driven manner by using extensive traces from Akamai's streaming network that include 23 million views from 6.7 million unique viewers. We show that viewers start to abandon a video if it takes more than 2

Transcoding Live Adaptive Video Streams at a Massive Scale in the Cloud

by Ramon Aparicio-pardo, Telecom Bretagne, Karine Pires, Alberto Blanc, Gwendal Simon
"... More and more users are watching online videos produced by non-professional sources (e.g., gamers, teachers of online courses, witnesses of public events) by using an increasingly diverse set of devices to access the videos (e.g., smartphones, tablets, HDTV). Live streaming service providers can com ..."

combine adaptive streaming technologies and cloud computing to satisfy this demand. In this paper, we study the problem of preparing live video streams for delivery using cloud computing infrastructure, e.g., how many representations to use and the corresponding parameters (resolution and bit-rate). We

Quality of Experience estimation for Adaptive HTTP/TCP video streaming using H.264/AVC

by Kamal Deep Singh, Yassine Hadjadj-aoul, Gerardo Rubino - in "CCNC - IEEE Consumer Communications & Networking Conference", Las Vegas , 2012
"... Video services are being adopted widely in both mobile and fixed networks. For their successful deployment, the con-tent providers are increasingly becoming interested in evalu-ating the performance of such traffic from the final users ’ per-spective, that is, their Quality of Experience (QoE). For ..."

E). For this purpose, subjective quality assessment methods are costly and can not be used in real time. Therefore, automatic estimation of QoE is highly desired. In this paper, we propose a no-reference QoE monitoring module for adaptive HTTP stream-ing using TCP and the H.264 video codec. HTTP stream-ing using TCP

Abstract Adaptive Video Streaming: Pre-encoded MPEG-4 with Bandwidth Scaling

by A. Balk, M. Gerla, M. Sanadidi, D. Maggiorini
"... The increasing popularity of streaming video is a cause for concern for the stability of the Internet because most streaming video content is currently delivered via UDP, without any endto-end congestion control. Since the Internet relies on end systems implementing transmit rate regulation, there h ..."

, there has recently been significant interest in congestion control mechanisms that are both fair to TCP and effective in delivering real-time streams. In this paper we design and implement a protocol that attempts to maximize the quality of real-time MPEG-4 video streams while simultaneously providing basic

Scalable Video Coding Based Video Streaming On JXTA Peer-to-Peer Network

by Youssef Lahbabi, Ensias Mohammed V, Ahmmed Hammouch, El Hassan Ibn Elhaj
"... Abstract:- Video streaming through peer-to-peer (P2P) networks using scalable video coding (SVC) has been an active research. In this way, we propose to design and implement such solution by using a JXTA peer-to-peer framework to share and stream scalable videos. This new architecture use jointly th ..."

the scalable video coding H.264/SVC and JXTA P2P network in term of video streaming especially Video-On-Demand (VoD). Most importantly, in this architecture we include some relevant metrics that reflect the key features of perceived video quality adaptation for different resources consumption. For this purpose
