Executive Summary

Global uptake of digital TV and increasing market pressures from alternative services are making cable television operators rethink their delivery of broadband. Particularly across North America, operators are rapidly deploying competitive services in order to retain customers and attract new ones.

Those under consideration include: switched digital video, 1-GHz systems, node splitting, wider Internet Protocol (IP) pipeline, and multimedia home networking solutions.
