Color video signal processing apparatus

摘要

A color video signal processing apparatus which utilizes a digital luminance data and first and second color difference signals which are digitized at a first sampling frequency and formed by matrix operation wherein at least one of the first or second color difference data is sampled at a second sampling frequency which comprises the first sampling frequency divided by an integer with the band width of the sample output being limited to a predetermined band width with a digital filter and the luminance and first and second color difference signals which have had their band width limited comprising the color video signal which is to be transmitted.
