In this system there are 2 tuners - ATSC/NTSC tuner(TDVS-H701P) and NTSC-only tuner.(TAFM-H103P)
So it is impossible to have a digital (main)/digital (sub) PIP.

CXA2181Q is the AV switch for the component signals and CXA2069Q is the AV switch for the composite signals.
The audio signals which separated by CXA2069 are sent to MSP4440.
AD9883 is AD converter and there are 2 NT decoders (uPD64011B) for main and sub NT signals each.

HD2.3 can receive TP data, MPEG2 video decoding and image processing. IEP2 chip enhances the output image quality.
Main CPU (PPC405GPr-266) is the central processing IC, which controls most of the ICs.
CPLD (XC95288, XC95144) implements the glue-logic.

1394 communicates to either direction and can give and take image, sound, or each control commands with only one cable (this TV
can communicate with DVHS / Camcoder).
HDMI port can receive video data via High-Definition Multimedia Interface (HDMI) or the Digital Visual Interface (DVI).
Sil9012 is HDMI receiver IC and TSB43DA42 controls the 1394 I/F.

This TV is capable of receiving basic analog, digital basic and digital premium cable television programming by direct connection to a
cable system providing such programming. A security card provided by cable operator (CableCard) is required to view encrypted digital
programming. Channel informations can receive in the OOB channel.
LGDT3701A demodulates the VSB/QAM signals and also OOB signal (QPSK).
LGDT3502B generates the CableCard I/F signals and decodes copy protected stream.
