(2) 3-line Y/C separation
The VIDEO signal output of Q5018 is processed for band limitation at FL5301. It is then processed for the
level and Characteristic F compensation at the AMP (Q5302 to Q5305) in the latter stage. After this com-
pensation, the signal input is entered from Q5304 to Pin 3 of IC5303, with the potential maintained at
1.3Vp-p.
In IC5303, 3-line Y/C separation is effected, and the Y signal is output from Pin 25, and the C signal from
Pin 23.
The Y and C signals are processed for band limitation at FL5302 and 5303, and they are double-amplified
at IC5304 and IC5305. The resultant signal input is entered in the SW circuit of IC5307 and IC5309.

The outputs of IC5306 and IC5307 (Signal Y) are changed over with the DVD signal at IC5507 (TC7W66;
SW) of the next stage. The output signal input is directly entered in Pin 17 of IC5504 as a sync signal.
Compensation for Character F and peaking are effected at Q5512 to Q5515, and the input is entered in
IC5504 (PAL/NTSC process).
The outputs of IC5308 and IC5309 (Signal C) are entered in IC5504 (PAL/NTSC process) and IC5510
(SECAM decoding).
