Abstract:
A method of receiving a field of transmitted data, wherein the field comprises E-VSB data segments containing E-VSB data and VSB data segments containing VSB data, the method comprising:receiving the field containing a map that designates a data segment mix contained in the received field; decoding the received map to determine the number of E-VSB data segments in the received field; determining the locations of at least the E-VSB data segments in the received field according to the following expression: s=Int(k*156/P) for k=0 to k=(2*Pâˆ’1) wherein P is the number of E-VSB data segments in the received field divided by two, wherein s designates segment number, wherein Int designates a rounding down operation, and wherein k varies from 0 to 2*Pâˆ’1; and,separating at least one of the received E-VSB and VSB data segments according to the segment number s.
