    摘要: 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.

    摘要翻译: 根据第一交错,正常排序的鲁棒VSB数据被重新排序以产生重排序的鲁棒VSB数据。 根据第二交错重新排序的稳健VSB数据和ATSC数据被重新排序以产生正常排序的鲁棒VSB数据和重新排序的ATSC数据。 通常排序稳健的VSB数据和重新排序的ATSC数据被时分复用以传输到接收机。 接收机根据接收机类型或用户选择丢弃重新排序的ATSC数据或正常排序的鲁棒VSB数据。 稳健的VSB接收机能够处理在外部解码器上游的正常排序的鲁棒VSB数据,而不会产生交错,从而避免与交织相关联的延迟。
