To provide a TMCC decoding circuit capable of decoding a transmission parameter changeover index at an accurate timing regardless of decoding processing time of TMCC data of the TMCC decoding circuit.
The TMCC decoding circuit is provided with a first means for outputting the transmission parameter changeover index after error correction by an error correction means as the transmission parameter changeover index when the transmission parameter changeover index after the error correction by the error correction means is binary data '1111', and a second means for outputting a result of subtracting the number of delay frames corresponding to processing time by the error correction means from the transmission parameter changeover index after the error correction by the error correction means as the transmission parameter changeover index in the case that the transmission parameter changeover index after the error correction by the error correction means is a value other than the binary data '1111'.
