ABSTRACT:
A video-signal-processing device configured to externally transmit at least one brightness signal and at least one color-difference signal is provided. A single frame of the color-difference signal is assigned to a plurality of frames of the brightness signal so that a first frame frequency of the color-difference signal is lower than a second frame frequency of the brightness signal, where the first frame frequency is 24 Hz or higher. The brightness signal and the color-difference signal are transmitted so that a first center value on a first time base generated by the single frame of the color-difference signal becomes closest to a second center value on a second time base generated by the plurality of frames of the brightness signal corresponding to the color-difference signal.
