9-1-1 Notes
The TVÕs 1st and 2nd tuners (and VCR module) are Òmulti-system.Ó compatible: IC201 (TDA8374) is
the video, chroma, and deflection (VCD) IC .
9-1-1(A) TAPE PLAYBACK (REGARDLESS OF ORIGINAL RECORDING SYSTEM)
If the output PB signal of micom pin 6 is high, the PB signal outputs from module deck 1, passes
through IC 702 pins 1 and 8 and out to another VCR . The output signal of IC701 pin 1 (pin 15)
outputs from IC201 pin 17 (RBG OUT).
9-1-1(B) VIEWING NORMAL CHANNEL WHILE RECORDING A SCRAMBLED CHANNEL:
The output CVBS (Composite Video Signal) of the 2nd IF outputs to pin 8 when the micomÕs pin 7
V/T/H (VCR tuner high) is high (IC702 pin 3). The decoded signal goes to IC701 pin 2, where it is fed
to IC 701 pin 4 (high output of micomÕsÕ pin 8Ñ AV/Tuner), and out to VCR pin 3 (module deck) for
recording.
9-1-1(C) VIEWING A SCRAMBLED CHANNEL WHILE RECORDING AN UNSCRAMBLED CHANNEL.
The output CVBS of the 2nd IF is fed from IC801 pin 5 to IC702 pin 4 (low output of micom
pin 8ÑAV/tuner). Then it goes to the module deck pin 3 for recording.
The scrambled signal (CVBS) is fed to IC702 pin 6 through the 1st IF, and then to IC702 pin 8 (micomÕs
pin 7, V/T/H registers low). Then it goes to the decoder input. The descrambled signal goes to IC701
pins 2 and 15 (PH high output of micomÕs pin 6), and then to IC201 pin 17, where it outputs as RGB.
9-1-1(D) SYNCHRONOUS RECORDING:
The viewer sees the signal from the 1st tuner , while the signal from the second tuner is recorded.
Audio processing for the French system type is shown in the table.
