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

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

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