Abstract:
An apparatus comprising:a converter for converting a digitally sampled interlaced video stream to a non-interlaced video stream; andan artifact masker, responsive to at least a first component of said non-interlaced video stream, for adaptively modifying said first component of said non-interlaced video stream to reduce artifacts introduced into said non-interlaced video stream by said converter to generate a modified non-interlaced video stream, wherein said masker comprises:a first processing module responsive to said non-interlaced video stream for performing a first processing function on said non-interlaced video stream;a second processing module responsive to said non-interlaced video stream for performing a second processing function on said non-interlaced video stream; anda third processing module responsive to said non-interlaced video stream for selecting output of said first processing module or said second processing module to generate said modified non-interlaced video stream.
