Existing distributed stream systems adopt a tightly-coupled communication paradigm and focus on fine-tuning of operator placements to achieve communication efficiency. This kind of approach is hard to scale (both to the nodes in the network and the users). ...
This paper addresses the problem of efficiently delivering a layered media stream from multiple senders to a single receiver, over channels that present correlated packet loss patterns. Using a digital fountain approach, the performance of a distributed st ...
The spatial modelling of extreme snow is important for adequate risk management in Alpine and high altitude countries. A natural approach to such modelling is through the theory of max-stable processes, an infinite-dimensional extension of multivariate ext ...
In standard database scenarios, an end-user assumes that all data (e.g., sensor readings) is stored in a database. Therefore, one can simply submit any arbitrary complex processing in the form of SQL queries or stored procedures to a database server. Data ...
This paper presents a framework for efficiently streaming scalable video from multiple servers over heterogeneous network paths. We propose to use rateless codes, or Fountain codes, such that each server acts as an independent source, without the need to c ...
In the following study is presented two research works: the first is concerned with the elaboration of an intelligent meeting room while the second is about the development of a real time high definition video server capable of advanced accessibility optio ...
In this paper, we describe a multimodal data flow controller capable of reading most multichannel sound cards and web cameras, synchronising media streams, being a server to stream captured media over TCP in raw format, being a client to receive media stre ...
The obvious recent advances in areas such as video compression and network architectures allow for the deployment of novel video distribution applications. These have the potential to provide ubiquitous media access to end users. In recent years, applicati ...
Peer-to-peer (P2P) systems are becoming increasingly popular due to their ability to deliver large amounts of data at a reduced deployment cost. While P2P systems foster the development of novel media applications, they also represent an interesting altern ...
