Abstract
A demodulator having an improved reliability of the decoding of a TMCC signal is used for digital broadcasting receivers for receiving digital broadcasting by layered transmission system. A pseudo-pattern generator () generates fixed pseudo-data which involves no error with respect to a main signal after a TMCC signal and maintains the convolution relationship, and inserts the pseudo-data between the TMCC signal and the main signal through a selector (B) and a selector (), thereby conducting Viterbi decoding.
