INPUT SIGNAL PARAMETERS INCLUDING

INPUT SIGNALS

1. Input signal name is two alphanumeric characters.

EX.)

SS

Standard Signal

Second character

First character

First character: Standard=S, Nonstandard=V

(Modified parts should be specified.)

Second character: Meaning of signal

2. Structure of input color signal

The following figure shows the structure of color signal.

eb(n+1)

ec(n+1)

H.sync

500mVP-P

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.

2) Amplitude and frequency of burst are represented as ed. In case

of standard signal, the amplitude is 285mVP-P.

3) Amplitude and frequency of chroma are represented as ec.

In case of standard signal, the amplitude is 570mVP-P and the

frequency is 3.579545MHz.
