About Input Signal Parameter Including Color Signal
1. The name of input signal is made of 4 alphanumeric characters.
Note)
S S 4 P
Standard Signal 4.43MHz PAL system
4th characters
3rd characters
2nd characters
1st characters
1st Characters : Standard=S , No standard=V (however, the part of change is specified.)
2nd Characters : Meanings of signal
3rd Characters : Expressed as burst and chroma frequency.
4(4.433619MHz), 3(3.579545MHz) (however, this is treated the same as SECAM standard signal in case of "S")
4th Characters : Expressed as color system.
N(NTSC), P(PAL)
2. Configuration of input color signal.
Configurations of color signal are shown in the figure below.

P-P
1. If the first character of a signal name is S (standard), the signal conforms to the standard color bar signal in types. However,
H.sync is to be added for input clamp. (The frequency of H.sync conforms to the 4th character. P: 50 Hz, N: 60 Hz)
2. The amplitude of burst and the frequency are given in eb. If they are standardized, the amplitude is 285 mV
P
-
P
and the frequency
conforms to the 3rd character of the signal name.
3. The amplitude of chroma and the frequency are given in ec. If they are standardized, the amplitude is 570 mV
P
-
P
and the
frequency conforms to the 3rd character of the signal name.
4. The phase correlation on the PAL type signal is shown in the figure below.
