Abstract
A phase shift correcting apparatus of a sync detector in a satellite broadcasting reception system corrects a phase shift of 180.degree. which makes output data after demodulation be absolutely different from an original data such that 47 sync is phase-shifted by 180.degree. to be detected as B8 sync data. For this, the number of B8 data and 47 data of input data is counted in a comparator and a counter to determine whether the phase shift of 180.degree. occurs or not, and data involving the phase shift is converted to have a normal data value when it is determined that the phase shift occurs, thereby improving reliability of a satellite broadcasting receiver and solving the problem of the different data output.
