GENERAL DESCRIPTION OF THE CHROMA 4 SYSTEM
Figure 5 shows a simplified block diagram representation
of the basic system using the MC44002/7 and its companion
device the MC44140 chroma delay line. The MC44002/7 has
been designed to carry out all the processing of video
signals, display controls and timebase functions. There are
two video inputs which can be used for normal composite
video or separate Y and C inputs. In either case, the inputs
are interchangeable and selection is made via the I2C bus.
The video is decoded within the MC44002/7 and involves
separation, filtering, delay of the luminance part of the signal
and demodulation of the chroma into color difference signals.
The luminance (called Y1) together with the demodulated
R-Y and B-Y are all then brought out from the IC. The color
difference signals then enter the MC44140 which performs
color correction in PAL and the delay line function in SECAM.
Corrected color difference signals then re-enter the
MC44002/7.
