Tuner TUV1236D receive the signal come from CATV signal Selects desired channel and
demodulate image composite signal (signal mark T1CVBS) by pin 14 of Tuner output to U19 PW328
VDC decoder via C224 and audio SIF signal (signal mark T1SND) by pin 15 of Tuner output to U29
MSP4450G via C396 for demodulating MTS/SAP.
MPEG Processor PWM2030:
When MPEG Transport Stream data input U29 PWM2030 internal decoder Separates MPEG video and
AC3 digital audio .The digital video output from PWM2030 Digital Video Signal Output port (19 Pins) to
U18 PW328 digital input port (port 1) . The digital audio output via I2S bus (MPEG_CL, MPEG_WS,
I2S_DI1) to the externally connected DA converter( U27 MSP4440K) and via SPDIF to optical(P5) &
Coaxial(P4) . Each of these functions was described in more detail in the sections that follow.
