Abstract

A method (200) and system (300) for detecting the presence of a digital television signal takes advantage of the periodic training sequence within the DTV signal. The method (200) and system (300) autocorrelate the digitally sampled received signal using a delay (410, 510) that is approximately the same as the period between training sequence. If a correlation peak is detected that exceeds a set threshold, it is determined that a DTV signal is present, otherwise it is determined that there is no DTV signal is present.
