ABSTRACT:
A decoder decodes digital color information data from an input section into a predetermined number of pieces of color information consisting of specific color information and specific luminance information. A first converter converts the specific luminance information of each of the predetermined number of pieces of color information into a digital luminance signal component. A second converter converts the two color difference signals uniquely defined by the relationship between the specific color information and the specific luminance information of each of the predetermined number of pieces of information into a digital color difference signal component. A modulator digitally performs balanced modulation for the two color subcarrier components having phases shifted by 90 degrees from a color subcarrier component generator by using the digital color difference signal components, and outputs digital carrier chrominance signal components. An adder adds the digital carrier chrominance signal components from the modulator and the digital luminance signal component, and outputs digital video signal components. A third converter converts the digital video signal components into an analog waveform and outputs an analog video signal.
