- In this paper, we propose an additional data transmission scheme for the ATSC (Advanced Television Systems Committee) terrestrial DTV (digital television) systems based on a low rate systematic irregular repeat-accumulate (SIRA) code. Unlike the previously proposed additional data transmission scheme using TxID (transmitter identification) signals, the proposed scheme conjuncted with a DTV VSB signal cancellation technique is suitable for high data transmission. Compared to the previous additional data transmission scheme based on a low rate systematic repeat-accumulate code, the BER performance of the proposed scheme is significantly improved. The additional data is encoded with a simplified IRA channel coding scheme and injected to the conventional VSB signals with the bury ratio (BR) of 27 dB. With the proposed scheme, an additional data of rate up to 1 Mbps can be transmitted along with the ATSC terrestrial DTV signals by minimizing the detrimental effects on the ATSC terrestrial DTV systems. © 2011 IEEE.
