Abstract

Abstract A cable television communication system network (10) comprising a remote hub (14) which is in communication with a plurality of head ends/central office (18) via a fibre optic interface, a plurality of user terminals (16) associated with each head end via a hybrid fibre coax interface and a plurality of interactive and broadcast video information providers (VIPs) (12) which are in communication with the remote hub (14). The remote hub includes means for formatting broadcast signals received from selected VIPs of the broadcast VIPs (12) for direct transmission to the head end/user terminal interfaces such that the user terminals (16) receive said formatted broadcast signals without reformatting by said headends, means for selectively controlling distribution of communication signals between said interactive VIPs and said headends (18), means for tracking usage of VIP services by said user terminals for at least billing purposes. Each said headend (18) means for facilitating interactive VIP communications between its associated user terminals 16) and said VIPs (12).

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 142 words
A communication system network comprising: a remote hub; a plurality of head ends associated with said remote hub via a fiber optic interface; a plurality of user terminals associated with each head end via a hybrid fiber coax interface; said remote hub comprising: means for communicating with interactive and broadcast video information providers (VIPs); means for formatting broadcast signals received from selected VIPs of the broadcast VIPs for direct transmission to the head end/user terminal interfaces such that the user terminals receive said formatted broadcast signals without reformatting by said headends; means for selectively controlling distribution of communication signals between said interactive VIPs and said headends; and means for tracking usage of VIP services by said user terminals for at least billing purposes; and each said headend including means for facilitating interactive VIP communications between its associated user terminals and said VIPs.
Claim 2
Dependent Claim 48 words
The system of claim 1, wherein communications over said headend/user terminal interfaces are at least frequency multiplexed into a plurality of downstream channels from said headends and upstream channels to said headends such that the number of downstream channels is substantially greater than the number of upstream channels.
Claim 3
Dependent Claim 27 words
The system of claim 2 wherein said upstream channels are paired with selected downstream channels and communications on at least selected channel pairs are time division multiplexed.
