A colour video signal processing apparatus supplied with luminance data (Y) and first and second colour difference data (I, Q), each being digitized at a first sampling frequency and formed by matrix calculations (4), wherein at least one of the first and second colour difference data (I, Q) is sampled (6I, 6Q) at a second sampling frequency which is equal to the first sampling frequency divided by an integer, the band of the sampled output is limited to be a predetermined band by a digital filter (7I, 7Q), and the luminance data (Y) and said first and second colour difference data (I, Q) whose bands have been limited are transmitted as recorded (10). |
