Network Coding: From Theory to Media Streaming

Free registration required

Executive Summary

The traditional multimedia coding and streaming architectures have been challenged in the recent years with emerging applications such as wireless low-power surveillance, multimedia sensor networks, and portable devices with multimedia coding and communication capabilities. The widespread deployment of efficient communication systems combined with the proliferation of digital media content from numerous sources has fostered the development of a novel media delivery framework built on ad hoc or overlay networks. Such architectures present a high diversity in terms of sources, paths and clients, which could be exploited for improved performance. However, these architectures necessitate appropriate distribution and coding strategies for proper exploitation of the network diversity.
