1. A spectral network system for transmission and reception of multi-band RF signals over a packet-switched network, comprising:
- a down sampler configured toextract at least one smaller bandwidth channel from a larger bandwidth channel, andconvert the at least one smaller bandwidth channel into at least one spectral channel, the at least one spectral channel being a digitized representation of the at least one smaller bandwidth channel;
a packet encoder configured to encapsulate the at least one spectral channel as encoded packet data, each packet of the encoded packet data including a time of creation (TOC) based on a global time reference and configured for transmission via the packet switched network;
a packet decoder configured to decapsulate and reconstitute the at least one spectral channel and to provide deterministic latency control of the transmission and reception of the multi-band RF signals based on the TOC of each packet; and
an up sampler configured to convert the at least one spectral channel into the multi-band RF signals and insert the at least one smaller bandwidth channel into the larger bandwidth channel.

9. An apparatus for transmission and reception of multi-band RF signals over a packet-switched network, the apparatus comprising:
-
means for converting one or more radio frequency signals into at least one spectral channel, the at least one spectral channel being a digitized representation of the one or more radio frequency signals; means for encapsulating the at least one spectral channel as encoded packet data, each packet of the encoded packet data including a time of creation (TOC) based on a time reference to preserve timing for the converted radio frequency signal during transmission via the packet switched network; means for transporting the radio frequency signal as the internet protocol packets via a terrestrial packet switched network; means for decapsulating and reconstituting the at least one spectral channel to provide deterministic latency control of the internet protocol packets based on the TOC; means for converting the internet protocol packets into the one or more radio frequency signals. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

-
receiving, at a first spectral network device, an RF transmission from a spectral channel source, the RF transmission having a bandwidth and two or more RF signals spanning one or more RF spectra, the two or more RF signals comprising message data, the message data having one or more analog RF signals; extracting a first RF signal and a second RF signal of the two or more RF signals from the RF transmission, the first RF signal and the second RF signal comprising less than the bandwidth; converting the first RF signal in into a first spectral channel as a digitized representation of the first RF signal and the second RF signal into a second spectral channel as a digitized representation of the second RF signal; encapsulating the first spectral channel and the second spectral channel as encoded packet data using packet forward error correction (P-FEC), each packet of the encoded packet data including a time of creation (TOC) based on a global time reference and configured for transmission via the packet switched network; transmitting, by the first spectral network device, the encoded packet data to at least a second spectral network device via the packet-switched network; and decapsulating and reconstituting the first spectral channel and the second spectral channel at the at least a second spectral network device; and converting the at least one spectral channel into the one or more multi-band RF signals. - View Dependent Claims (20)
