Abstract
At least a first and a second digital signal, both in parallel form, are converted to a single serial signal and transmitted from a digital color decoder to a signal processing unit so as to avoid picture disturbances in the signal processing unit. The first digital signal is dependent on the instantaneous value of a clock frequency used in the decoder for processing a digital color picture signal, and the second digital signal is dependent on the instantaneous value of a chrominance subcarrier frequency generated in the decoder and used for color decoding.
