Abstract
A system, method and apparatus are provided for generatinga sandcastle signal in a television signal receiver, and utilizing the sandcastle signal during television signal processing. In one form, the sandcastle signal is generated by subtracting a separated synchronization signal of a television signal from a deflection retrace signal of the television signal receiver. In another form, the sandcastle signal is generated in a television and includes subtracting a separated synchronization pulse from a horizontal flyback pulse, a vertical retrace pulse, or a composite pulse formed by summation of a horizontal flyback pulse and a vertical retrace pulse. The sandcastle signal may be utilized by the television signal receiverduring a function of the television signal receiver, such as during a channel change.
