1. A gateway for redistributing an information signal of a specified bandwidth within a service area, comprising:
- a spectrum detector for identifying k pieces of white space sufficient to accommodate the specified bandwidth of the information signal, where k is an integer, k≧
1; and
a transmitter for transmitting the information signal over the identified k pieces of white space.

Abstract
Redistribution of multimedia signals or the like within a service area is performed by identifying one or more pieces of white space in the VHF/UHF spectrum, selecting a carrier frequency for each piece of white space spectrum, parsing the signal into a like number of components and modulating each component over a carrier frequency. The receiving device performs the reverse operation for reconstructing the signal.
