A method is disclosed for delivering broadband video data to an end user device comprising transmitting broadband video data via a radio frequency transmitter to a home radio frequency receiver located at a residential power transformer providing electrical power to a home; coupling the broadband video data from the home radio frequency receiver to a first modem onto a copper power line electrically coupled to the residential power transformer; receiving the broadband data on a second modem from the copper power line; and sending from the second modem, different portions of the broadband data to each of a plurality of end user devices in the home. A system and computer program for performing the method are disclosed.

A method of transporting digital data over coaxial cable comprising converting digital signals associated with data into data electrical signals, positioning at least one repeater station, along a coaxial cable, restoring digital signals from the data electrical signals at the repeater station, and converting the digital signals back into data electrical signals at the repeater station for onward transmission. Typically a plurality of repeater stations are disposed at spaced-apart intervals along the coaxial cable with each repeater station comprises a receiver and transmitter, the receiver receiving data electrical signals and restoring these into digital signals with the transmitter converting the digital signals back into data electrical signals for onward transmission. The data electrical signals have a frequency of at least 2 GHz.

A method of segmenting an access network of a hybrid fiber coaxial network, the method comprising receiving optical signals at a main node converting the optical signals into digital signals associated with data and electrical signals associated with a broadcast spectrum, converting the digital signals into electrical signals in a frequency range differing from a frequency range of the broadcast spectrum electrical signals, producing a combined electrical signal with separate frequency bands for data and broadcast spectrum signals, and conveying the combined signal along a coaxial cable to a plurality of subsidiary nodes. Frequencies associated with a first Narrowcast band within the broadcast electrical spectrum signal are replaced with frequencies associated with a second Narrowcast band.

Methods and apparatus for distributing content using a spectrum generation device. In one embodiment, digital content is received via a time-multiplexed network transport (such as Gigabit Ethernet), and converted to frequency channels suitable for transmission over a content distribution (e.g., Hybrid Fiber Coaxial (HFC)) network. In one variant, the conversion is performed using digital domain processing performed by a full spectrum generation device. Additionally, methods and apparatus for selectively adding, removing, and/or changing digital content from the full spectrum device are also disclosed. Various aspects of the present invention enable physical (infrastructure) consolidation, and software-implemented remote management of content distribution.

A distribution point unit to exchange communication data between a service provider and subscribers. The distribution point unit may include a first port to couple the distribution point unit to an optical data network to exchange communication data between the distribution point unit and the service provider, and a second port to couple the distribution point unit to an electrical data network to exchange the communication data between the subscribers and the distribution point unit. The distribution point unit may also include a third port to couple the distribution point unit to an electrical device, the third port being configured to provide control data to control the electrical device.
