Abstract
A field contains a map, a number of E-VSB data segments, and a number of VSB data segments. The map indicates at least the number of E-VSB data segments in the field. The E-VSB data segments are located in the field such that the spacing between the E-VSB segments comprises only x and x+1, where x is dependent on the number of E-VSB data segments in the field as indicated by the map.
