Abstract
A first interlaced video signal of a first number of scanning lines is converted into a second interlaced video signal of a second number of scanning lines. The first and second numbers are different from each other. The first interlaced video signal is converted into a first progressive video signal of the first number of scanning lines by interpolating the first interlaced video signal with scanning lines which have been decimated from the first interlaced video signal. The first number of scanning lines of the first progressive video signal is converted into the second number of scanning lines by re-sampling, to generate a second progressive video signal of the second number of scanning lines. The second progressive video signal is then converted into the second interlaced video signal by decimating the second number of scanning lines of the second progressive video signal. Instead of generation of the second progressive signal, one of an even and odd frame of the first progressive video signal may be converted into an even field of the second interlaced video signal and the other of the even and odd frames of the first progressive video signal may be converted into an odd field of the second interlaced video signal. The even and odd fields are combined to compose the second interlaced video signal.
