Abstract: Normally ordered robust VSB data are reordered in accordance with a first interleave to produce reordered robust VSB data. The reordered robust VSB data and ATSC data are reordered in accordance with a second interleave to produce normally ordered robust VSB data and reordered ATSC data. The normally ordered robust VSB data and reordered ATSC data are time multiplexed for transmission to a receiver. The receiver discards the reordered ATSC data or the normally ordered robust VSB data depending upon receiver type or user selection. A robust VSB receiver is able to process the normally ordered robust VSB data upstream of an outer decoder without an interleave thereby avoiding the delay associated with an interleave.

Abstract: Frames comprise odd fields and even fields. The frame sync segments of the odd fields contains a current map specifying the location of data in frames, a next map specifying the location of data in a future frame, and a frame count designating the future frame. The frame sync segments of the even field may contain the same information. Alternatively, the frame sync segments of the odd fields contain the current map and part of the frame count, and the frame sync segments of the corresponding even fields contain the next map and the rest of the frame count. A receiver uses the map and frame count information to find data in the fields of received frames.
