Устройство для обработки сигнала цветности, в котором поднесущая сигнала цветности и поднесущая сигнала цветности пониженной частоты формируются с помощью общего осциллирующего сигнала, и используемый в нем способ создают поднесущую сигнала цветности пониженной частоты. Устройство обработки сигнала цветности для понижения его частоты включает в себя генератор для выработки осциллирующего сигнала заранее заданной частоты, генератор поднесущей сигнала цветности для приема осциллирующего сигнала для выработки поднесущей сигнала цветности, демодулятор сигнала цветности для демодуляции сигнала цветности, входящего в составной видеосигнал, генератор поднесущей сигнала цветности для приема осциллирующего сигнала для выработки поднесущей сигнала цветности пониженной частоты, модулятор сигнала цветности для приема сигнала цветности, демодулированного в демодуляторе сигнала цветности, и поднесущей сигнала цветности пониженной частоты для выработки сигнала цветности пониженной частоты. Когда сигнал обрабатывается в системе NTSC или в системе ПАЛ, устройство обработки сигнала цветности выполняет обработку сигнала цветности с помощью осциллирующего сигнала.A device for processing a chrominance signal, in which the chrominance subcarrier and chrominance subcarrier of a chrominance signal are generated using a common oscillating signal, and the method used in it creates a chrominance signal's subcarrier of a lower frequency. A chrominance signal processing device to lower its frequency includes a generator to generate an oscillating signal of a predetermined frequency, a chrominance subcarrier generator to receive an oscillating signal to generate a chrominance signal subcarrier, a chrominance demodulator to demodulate a chrominance signal included in a composite video signal, a signal subcarrier generator chrominance for receiving an oscillating signal to generate a lower frequency chrominance subcarrier, signal modulator and for receiving the chrominance signal demodulated in the chrominance demodulator and a chrominance subcarrier to produce a low-band low-band chrominance signal. When a signal is processed in an NTSC system or in a PAL system, the chrominance signal processing device performs the chrominance signal processing using an oscillating signal.
