Abstract
Data rates of a first video signal and a second video signal which are significantly different are converted to respective predetermined data rates, and both the video signals of one frame are divided into respective numbers of macro block. A ratio of the number of macro block of the first video signal to the number of macro block of the second signal is made to 1:n, where n is a natural number, and a ratio of the number of pixel in one macro block of a color difference signal of the first video signal to the number of pixel in one macro block of the color difference signal of the second video signal is made to 1:m, where m is a natural number. A ratio of the data rate of the color difference signal of the first video signal to the data rate of the color difference signal of the second video signal is made to 1:n.times.m and a ratio of a moving speed of a magnetic tape in the first video signal to a moving speed of the magnetic tape in the second video image is made to 1:n.
