Abstract
An on-demand program access system for broadband, frequency division multiplexed cable television signals, one or more infrastructure element (IF) constituting a local video network signal server has a plurality of subscriber premise equipment elements (SPEE) served thereby. Each SPEE constitutes a video network client. Coaxial premise wiring connects each SPEE with the IE for conducting RF modulated programming signals and bi-directional data signals between the IE and each respective SPEE using out-of-band signaling so that there is no overlap between the programming signals and the bi-directional data signals.
