Adapting CATV broadcast networks for broadband interactive symmetrical services

This paper develops the themes of 'demand' for 'integrated broadband communications (IBC) services' then analyses the current state of CATV in Europe. The necessary steps in re-engineering mature CATV networks to become full service networks (FSN) in the immediate future are estimated, and a description is provided of an evolutionary strategy for transforming large and mature tree-and-branch CATV networks to IBC, using first the introduction of managed video communications tele-services, fast Internet access, and WAN 'cable-LAN-LAN' connections for fast data communications and conferencing services. Some observations are made concerning likely migration paths for distinct network types, and specific solutions known at the present time.
