On-demand video streaming applications are attracting an ever-growing number of users on the Internet. As new terminals, and especially mobile ones, give their users the ability to film and edit videos, it is necessary to provide efficient and scalable solutions that enable users to share their creations with as many users as they want. Traditional client-server-based video streaming solutions can...
A key challenge in Distributed Virtual Environments' (DVE) research has always been the possibility to compare new connectivity strategies with state of the art solutions without having to re-implement it. Indeed, when considering distributed connectivity strategies that allow multiple processes (eventually the end-user processes) to distribute the computation of a specific DVE task (i.e., objects...
It is well-known that networked multi resolution contents are designed and optimized to be exchanged between a provider and one or more requesters while allowing the best possible reproduction quality to all requesters. According to participants' terminal computing resources, push or pull modes can be used to distribute the reproduction load (i.e., server scalability versus light weight clients)....
Peer-to-peer (P2P) architectures have recently become a popular design choice for building virtual environments (VEs). In P2P-based VEs, peer connectivity between the different VE users depends on their positions in the virtual world regardless of the underlying physical network, which is subject to redundant hops and delay. In this paper, we propose Tri-Cast, a fully-distributed P2P architecture...
The recent availability of broadband Internet access and web-based visualization techniques is paving the way for a large scale use of 3D landscape and city models in a great variety of professional and mass market services. To make such services appealing to a large audience, these 3D models must reach a sufficient level of realism and accuracy. Many solutions are now available to automatically generate...
