Media-on-demand network, and a method of storing a media asset in a streaming node of the network

摘要

A method is provided of storing a media asset in a streaming node of a media-on-demand network. The network comprises a library node connected to a plurality of streaming nodes. The method comprises determining a popularity estimate for the asset at each of a plurality of the streaming node. The popularity estimates are aggregated to provide an aggregate popularity estimate for the asset over multiple streaming nodes. A determination is made whether the aggregate popularity estimate exceeds a predetermined threshold. Upon the threshold being exceeded, the asset is stored in one of the streaming nodes for use in addressing a request for the asset.
