Abstract
A method and apparatus for providing adaptive horizontal synchronization (sync) signal detection to identify whether a high quality television signal is being received by a television set. The method determines whether no signal is applied, whether a weak signal is applied or a strong signal is applied to the television set by sampling and processing the horizontal synchronization signal. The signals are classified by comparing the sample horizontal synchronization signals to a predefined threshold. The threshold is established based upon the type of source that produced the television signal.
