Working principle analysis of the unit
The RF1 via integrative tuner TUNER1 after, the FBAS VIDEO1 and SIF1 is generated. Video
signal of VIDEO1, AV1/S, AV2 sent to N7(TVP5160) as the main picture signal. The signal via N7
switch selection after, one way is AV OUT; another way sent 8-bit ITU-R656 format signal to N10
(FLI2310) non-interlaced processing, then sent 24bit YUV signal to main processing control chip
N15 (GM1501/1601).
The RF2 via integrative tuner TUNER2 after, the FBAS VIDEO2 and SIF2 is generated. Video
signal of VIDEO2,AV1/S,AV2 sent N8 (TVP5147) to decode as sub-picture signal. The signal via N8
decode after, it sent 8-bit ITU-R656 format signal to main processing control chip N15
(GM1501/1601).
Two ways YPBPR signal via HDTV switch N39(PI5V330) selection after, it sent to RGB switch
device N4(PI5V330) switch selection with RGB signal from VGA interface, then it sent to
GM1501/1601.
The HDMI via receiver N34(MST3383MB) processing after, it output RGB signal of 24bit to
GM1501/1601.
They sent to GM1501/1601 picture processing, therein YPBPB or RGB to A/D conversion after, it
and other three signal are switched selection and digital display processing, it include OSD,
GAMMA correction, brightness and contrast processing, then LVDS conversion to PDP panel
display.
The SIF1 of tuner1, SIF2 of tuner2 and audio signal of AV1/S, AV2 separate sent to audio processor
NA3(MSP3420).
The HDMI via chip N34(MST3383MB) decode to digital audio, after N26(CS4334) D/A conversion, it
audio and the audio signal of VGA/DVI sent to N44(HEF4052) switch selection, then sent to
MSP3420.
The audio of two YPBPR and VGA via switch conversion N42(HEF4052) to MSP3420 too.
The stereo of the SIF1 and SIF2 with other four ways audio switch conversion selection to volume
control and audio processing. One way output right/left channel audio of main-picture, the signal
sent SRS processing NA5 (M62494) to SRS sound stereo processing. It via sound amplifier
NA6(MP7722) to speaker; one way output right/left channel audio of sub-picture, it sent to earphone,
another way is AV OUT R/L output.
The work of whole unit is controlled by MCU, which includes GM1501/1601.
