A system for processing and recording digitized component television signals onto analog video tape includes a digital color transformation matrix for generating a digital luminance signal, a first digital chrominance signal, and a second digital chrominance signal. The signals are then sample rate reduced, interleaved, and stored in a storage subsystem, which may include a disk array. The storage subsystem allows a constant rate, uninterrupted data stream to be produced. To record the signals onto video tape, the signal data is read from the storage subsystem and separated. A series of digital signal processing elements, coupled to the digital luminance signal (read from the storage subsystem), are used to generate a digital filtered and frequency modulated luminance signal. A second series of digital signal processing elements, coupled to the first and second digital chrominance signals (also read from the storage subsystem), are used to generate a digital low pass filtered and amplitude modulated composite chrominance signal. These signals are combined, then converted into an analog composite recording signal compatible with a predetermined VCR standard.
