Abstract:
1. A system for delivering a plurality of video blocks to a user terminal service by a remote node, comprising: a plurality of broadband signal sources for providing a plurality of broadband signals, wherein each broadband signal is comprised of a plurality of optical bands; a plurality of modulators, wherein each of said plurality of modulators impress one of said optical bands with a composite signal representing data in a plurality of independent RF blocks to form a plurality of modulated signals, wherein said optical bands nominally match a Free Spectral Range (FSR) of a Waveguide Grating Router (WGR) at said remote node; a device for combining to form a combined broadcast signal from said plurality of modulated signals; a feeder fiber, wherein said remote node receives said combined broadcast signal via said feeder fiber; a passive splitter to split said combined broadcast signal, wherein said split combined broadcast signal is introduced to said WGR on a plurality of input ports associated with said WGR, wherein a stack of RF blocks represents one optical band of said plurality of optical bands; a distribution fiber for distributing said combined broadcast signal to a user's site; an optical filter for selecting a stack of RF blocks; a block-converter for converting said stack of RF blocks; a bandpass filter for retrieving said selected RF blocks from said block-converted stack of RF blocks; and further wherein a satellite set-top box selects a RF block.
