Abstract:
A method for broadcasting, comprising the steps of:receiving information to be broadcast;formatting said information to be broadcast into a broadcast signal;transmitting said broadcast signal to a receiver via a first transmission protocol, said first transmission protocol comprising one of a plurality of transmission protocols, said plurality of transmission protocols comprising frequency band transmission protocols, mode transmission protocols and multiple access methodology protocols, said frequency band transmission protocols comprising a transmission protocol for a first set of frequency bands and a transmission protocol for a second set of frequency bands, said mode transmission protocols comprising a transmission protocol for a narrowband signal transmission and a protocol for a spread spectrum signal transmission, said multiple access methodology protocols comprising a code division multiple access transmission protocol, a frequency division multiple access transmission protocol, and a time division multiple access transmission protocol; andreceiving said broadcast signal with a dual mode receiver contemporaneously with transmitting a signal via a second transmission protocol, wherein said first transmission protocol and said second transmission protocol comprise separate transmission protocols, said dual mode receiver comprising a mode controller, a first transmission protocol receiver, and a second transmission protocol receiver, said mode controller capable of selecting said first transmission protocol receiver or said second transmission protocol receiver.
