CIRCUIT

4. SWITCHING OPERATION

In this switching system, Video signals are selected by two A/V SW ICs (KA8119B & LA7152), Audio signals are
separately selectd by Hi-Fi IC itself which was controlled by the I

2

C bus. - W3D1, W3D2 mean the serial data bits for

the selection. -Refer below the table.

KA8119B contains the C+ SWs for Audio and Video signals. So Video and Audio signals are controlled by AV3 and
AV4 at the same time.
The item “Video Sel” means the input pin number of AV one chip IC(LA71511M). At the case 15, 16 Video input shall
be selected with Pin 32 (C+ discrambled signal).
If the power’s off at the state selected with F.AV, the SW mode is Case 16, 17 (For only VCR mode).

(1) CANAL plus mode.
