System for flexible multiple broadcast service delivery over a WDM passive optical network based on RF block-conversion, of RF service bands within wavelength bands

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.
