    摘要: Systems and methods for protecting DSL systems against impulse noise are provided. Disclosed herein are example embodiments of a retransmission technique located above the gamma interface (i.e., in the network processing layer). Such a retransmission technique can be combined with standard RS coding with standard erasure-decoding & triangular interleaving at the PMS-TC layer. Example embodiments of the technique involve using the RS code to protect against REIN noise, and using γ-layer retransmission for protecting against error events not corrected by the RS code, e.g. a SHINE noise in the presence of REIN. Both techniques are used jointly in the case of combined REIN and SHINE noise.

    摘要: A distribution node among a network of distribution nodes for packet based distribution of voice, video and data packets including multicast packet based distribution of video channels from at least one video server distribution node to a plurality of client distribution nodes selectively consuming the video channels is disclosed. The distribution node comprises a responsive to selection of a new video channel to identify a sub-set of packets within a set of packets of the new video channel for expedited delivery and to expedite delivery of the identified sub-set of packets; thereby reducing switchover latency of the distribution node in response to a selection of the video channel.
