ABSTRACT:
A method and apparatus for removing national television system committee (NTSC) signals from a broadcasted datastream including advanced television system committee (ATSC) signals are provided. The apparatus includes an NTSC signal removing unit for removing the NTSC signal from an input signal with one or a plurality of NTSC filtering units; a vestigial sideband (VSB) core unit for generating an error generating signal if the NTSC signal is not removed by the NTSC signal removing unit for a continuous time period of at least a predefined length; and an NTSC filtering selection unit for applying a control signal to select a different one of the NTSC filtering units in response to the continuous error signal output by the VSB core unit.
