A transmitter transmits successive data fields, and each data field includes a mix of VSB data segments and E-VSB data segments and interleaved portions of maps. The maps define the mixes of VSB data segments and E-VSB data segments in corresponding data fields to b transmitted after the correspondingmaps are transmitted. Prior to interleaving, the maps are encoded. At a receiver, the maps are de-interleaved and decoded so as to derive the mix of VSB and E-VSB data segments defining each of the data fields. The interleaving and de-interleaving have a combined latency of at least L fields. The VSB and E-VSB data segments of each of the data fields are separated in response to the de-interleaved maps. |
