INPUT SIGNAL
VIF/SIF
INPUT SIGNAL PARAMETERS INCLUDING
INPUT SIGNALS
1. Input signal name is four alphanumeric characters.
First character:
Standard=S, Nonstandard=V
(Modified parts should be specified.)
Second character: Meaning of signal
Third character:
Frequency of burst and chroma.
4 (4.433619MHz), 3 (3.579545MHz)
(In case of "S", SECAM standard signal is
applied.)
Color system
N (NTSC), P (PAL)
Fourth character:
2. Structure of input color signal
The following figure shows the structure of color signal.
1) When S (standard) is used as the first character, the standard
color bar signal of each system is applied. H.sync should be
added for input clamp. (The frequencyof H.sync is fixed
according to the fourth character. P:50Hz, N:60Hz)
2) Amplitude and frequency of burst are represented as ed. In case
of standard signal, the amplitude is 285mV
P-P
and the
frequency is shown by the third character.
3) Amplitude and frequency of chroma are represented as ec.
In case of standard signal, the amplitude is 570mV
P-P
and the
frequency is shown by the third character.
4) The following figure shows the phase of a PAL system signal.
