Abstract: A novel node device enables transmission of a wideband signal, in compliance with various acceptable transmission standards and protocols. The signal consists of the legacy spectrum of about 5-860 MHz as well as a new downstream spectrum of about 1000-2000 MHz and a new upstream spectrum of about 2000-3000 MHz or about 930-1100 MHz. The novel device enables transfer of additional data in the upstream direction employing multiple upstream bands without making substantial investment in upstream physical node splitting thus providing networking services to residential subscribers, as well as to small and medium-sized businesses (SMB), which may operate under existing DOCSIS protocols and controlled by standard DOCSIS routers (CMTSs).

Abstract: A system and method for the expansion of the spectrum by the generation and introduction of high frequency spectrum overlays is disclosed. In an electronic content distribution system a plurality of input stream are combined at a head end into two combined signals having separate frequency band ranges. The signals are transmitted to the network and are dynamically combined into a single signal where the spectral composition of the signal is controlled by pre-defined parameters. The first signal carries a plurality of existing channels while the second signal could carry an additional set of channels. The second signal could carry spectral overlays generated from specific input streams the in accordance with pre-defined system parameters. The spectral overlays are selectively extracted from the second signal and introduced into the combined signal in the network in accordance with pre-defined subscriber-specific information.

Abstract: A system and method for spectral node splitting in cable TV network based on hybrid fiber-coax architecture is disclosed. Two-way optical signals carrying video and/or multimedia content are received at a signal distribution node. Portions of the received signals are processed according to the functionality the direction thereof. Certain frequency ranges are passed intact while specific different downstream and specific different upstream frequency bands are converted in a manner as to be allowed to be multiplexed into an extended broadband signal. The frequency bands within the extended broadband signal are distributed selectively among separate branches of the network. The frequency bands dedicated to the upstream traffic are received selectively from the separate network branches to be back converted and transmitted upstream to the network controller.
