Abstract

The device according invention has a programme memory wherein fragments of a broadcasted programme are temporarily stored, and is able to share programme fragments with similar devices in order to recompose the broadcasted programme at a time-shifted moment. By integrating devices according to the invention in network nodes, like for instance access network aggregating nodes (DSLAMS, DLCs, Fibre Aggregators, remote DSLAMs), and/or switches, routers and/or home-based terminals, a distributed Personal Video Recorder is for instance realized.
