In the objective of improving the video quality as perceived by end-users, multipath video streaming in Video Distribution Network (VDN) comes as a promising solution. In this paper, we present a new adaptive mechanism to maximize the overall video quality at the client. Overlay path selection is dynamically done based on available bandwidth estimation,(More)
Our main focus in this paper is to determine the most appropriate method for assessing the Quality of Experience (QoE) in the context of Multiple Description Coding (MDC) video streaming, over multiple overlay paths, in video distribution networks (VDN). For this objective, we compare three different types of QoE assessment approaches, subjective approach,(More)
In this paper we propose a multipath video streaming mechanism based on the Scalable Video Coding (SVC) extension of H.264/AVC. Our method adapts to the heterogeneous capabilities of different end-users. Additionally, it adapts to network bandwidth fluctuation by observing the changes in the available bandwidth over the multiple overlay paths, and updating(More)
In the domain of content delivery over Internet, each of the Client/Server and P2P communication modes has its pros and cons. In this scope, hybrid network architectures have been recently proposed as a relevant solution. In this paper we propose a new hybrid architecture that is called P2PWeb, between the centralized client/server and the non-centralized(More)
In the objective of streaming the video to the end-user with the best possible quality, in this paper we propose an approach that couples the SNR scalable video coding (SVC) extension of H264/AVC, with the path diversity provided by video distribution network (VDN). Our method adapts to the heterogeneity of end-users using the scalable video coding.(More)
In the domain of video streaming, Scalable Video Coding (SVC) comes as a solution that adapts to network bandwidth fluctuation and to terminals heterogeneity. The multilayer-coding criterion of SVC has increased its correlation with the streaming over multiple paths. However, an important challenge that we still need to face is how to maximize the overall(More)
In this paper we propose a new hybrid architecture between client/server and P2P network architectures in order to provide better service quality to the end-user. To distribute and protect the content, we use a discrete geometry tool as the Finite Radon Transform (FRT) in a Maximum Distance Separable (MDS) fashion. The presented results clarify the interest(More)
