<p>PROBLEM TO BE SOLVED: To provide a display device of an error rate which prevents the display of an erroneous error rate. SOLUTION: A transmitted signal is decoded as an output in Viterbi decoding by a Viterbi decoder 1. When conducting Viterbi decoding, the Viterbi decoder 1 inputs an error flag into a Viterbi error rate processing circuit 4. The transmitted signal deinterleaved by a bite de-interleaving circuit 2 is decoded in Reed- Solomon code by a Reed-Solomon decoder 3. The Reed-Solomon decoder 3 inputs an error flag into an error rate display circuit 7. The error flag from the Viterbi decoder 1 is input into a Viterbi error rate processing circuit 4 to calculate a first error rate. A Reed-Solomon error rate processing circuit 6 retrieves the error flag from the Reed-Solomon decoder 3, to calculate a second error rate. A Viterbi decode control signal, a 47h detection signal, the first error rate, the second error rate, and a correction disability flag are input into an error rate display circuit 7 and displaying is made.</p> |
