OVERALL CIRCUIT DESCRIPTION“Overall Block Diagram” on page 12 provides an overview of theAZ3Fchassis.Thefollowingaredescriptionsoftheboardsandtheirfunctions.

MAIN BOARDCommon toallmodels theMainBoard,designatedas theBAPSBoard,contains the TV control, video, and audio processing circuitry.All thesefunctionsareaccomplishedusingtheX-RealityProcessorIC9000.

TUNERThe tuner is a combination ATSC/NTSC unit. It can receive traditionalanalogNTSCsignalsviacableorterrestrialalongwithATSCdigitalsignalsviaterrestrial(8VSB)orcable(64or256QAM).

X-REALITY PROCESSORIC9000performsthemajorityofthenecessaryaudioandvideoprocessingontheMainBoard.TV Microprocessor: TheCPUinternaltotheX-Realityprocessorcontrolsall aspects of the television functions. Input from the user along withmonitoringofcriticalcircuitsisalsoperformedbythisCPU.Digital Audio and Video Decoder: TheMPEG2andDigitalDolbyaudiostreamsarereceivedfromthetunerfordecompression.Allvideosourceswhich are not native 1920 X 1080p 60HZ are scaled to this resolution.DigitalaudiocontentisoutputtotheclassDamplifierforprocessingandamplification.HDMI Input and Switching:ThecustomercanselecttheHDMI1,HDMI2,HDMI3,HDMI4inputviatheHDMIswitchIC5500.EachHDMIinputcontainsacommonEDINVM(internaltoIC5500)toprovidedisplayinformationdatatoanydeviceconnectedviatheHDMIinputs.LVDS Transmitter: Integrated into IC9000 is a Low Voltage Differential Signaling (LVDS) transmitter.Thiscircuit converts the8-bitparallelRGBvideo information into a set of high speed serial lines for noise-freetransmissiontotheTCONBoardcircuitslocatedinternallytotheLCDPanel.

Scan Converter: Signal processing circuit that performs resolutionconversion(aspectratio)andinterlacedtoprogressivescan(IP)conversion.

AUDIO AMPLIFIERThe main speaker audio amplifier (IC4601) and sub-woofer amplifier(IC4701)amplifiesthedigitalaudiooutputoftheX-Realityprocessorandsendsittothespeakers.
