The present application discloses a video signal processing apparatus for minimizing cross-color and cross-luminance interference in a composite video signal. A first filter is coupled to a color difference signal input terminal and generates a signal occupying a first region of a predetermined spatio-temporal frequency space. A second filter is coupled to a brightness signal input terminal and generates a signal occupying a second region of the predetermined spatio-temporal frequency space exclusive of the first region. An encoder forms a composite video signal from the filtered color difference and brightness signals such that they occupy mutually exclusive spatio-temporal frequency spaces. A television receiver for decoding the composite video signal is described which comprises the serial connection of a vertical-temporal filter and a horizontal filter. Filters are also disclosed for the first and second filters described above which are the serial connection of vertical-temporal filters and a horizontal filter. Specific vertical-temporal filter arrangements are also disclosed.
