摘要： PROBLEM TO BE SOLVED: To enable data transmission insusceptible to multi-path fading or ghost by performing RS coding of transmission data multiple times, and to improve the transmission tolerance without decreasing the transmission amount of data by efficiently utilizing auxiliary data to be used in an OFDM modulation system.
SOLUTION: This data transmission apparatus is one for performing transmission using a main data carrier and an auxiliary data carrier. The apparatus consists of a first coding processing unit for at least applying error correction coding to the transmission data, a second coding processing unit for doubly applying error correction coding to a signal from the first coding processing unit, and a modulating unit for modulating a signal from the first coding processing unit and a double error correction coder from the second coding processing unit. The modulating unit uses the main data carrier to transmit the signal from the first coding processing unit, and the double error correction coding unit uses the auxiliary data carrier to transmit the signal from the first coding processing unit.

摘要： PROBLEM TO BE SOLVED: To provide a system for digital broadcast and a method of digital broadcast capable of properly receiving superimposed data in an auxiliary channel of the received hierarchy even if at least a part of the hierarchy only is received in digital broadcast.
SOLUTION: Data of the auxiliary channel are generated for each hierarchy. Data of an auxiliary channel for an A hierarchy are superimposed on an AC carrier of the A hierarchy and that of an auxiliary channel for a B hierarchy is superimposed on an AC carrier of the B hierarchy. Even in such a case that the partial reception of the A hierarchy only is made, such a situation can be avoided that auxiliary channel data superimposed on the AC carrier cannot be used in an event of partial reception as in a conventional case, because data superimposed on the AC carrier of the A hierarchy are for the A hierarchy.
