摘要Abstract: Scalable video delivery over peer-to-peer networks
appears to be key for efficient streaming
in emerging and future Internet applications.
Contrasting the conventional server-client
approach, here, video is delivered to a user in a
fully distributed fashion. This is, for instance,
beneficial in cases where a high demand for a
particular video content is imposed, as different
users can receive the same data from different
peers. Furthermore, due to the heterogeneous
nature of Internet connectivity, the content
needs to be delivered to a user through networks
with highly varying bandwidths. Moreover, content
needs to be displayed on a variety of devices
featuring different sizes, resolutions, and computational
capabilities. If video is encoded in a
scalable way, it can be adapted to any required
spatio-temporal resolution and quality in the
compressed domain, according to a peer bandwidth
and other peers’ context requirements.
This enables efficient low-complexity content
adaptation and interoperability for improved
peer-to-peer streaming in future Internet applications.
An efficient piece picking and peer
selection policy enables high quality of service in
such a streaming system.
