Abstract
The image represented by a video signal contains an associated image spectrum defined within a spatial-temporal frequency volume. From this video signal, a second video signal is produced that represents spatial-temporal carrier modulation of a spectral section of the image spectrum into an interleaved location adjacent the image spectrum. To reduce the visibility of aliasing artifacts, the interleaved spectral section is made to be of reduced amplitude relative to its original amplitude in the image spectrum. To reconstruct the spatial-temporal frequency spectrum of the image at the television receiver, the video signal containing the frequency interleaved spectrum is processed in a complementary manner that represents spatial-temporal carrier modulation of the interleaved section to restore that section to its original position in the image spectrum. At the same time, the amplitude of the restored section is increased.
