II DNle:Usesa noise-filtering and picturequalityimprovement a lgorithmto implementnaturalcolors.
II Tuner:Two HD tuners,eachtakingthe role of the analogtuner.
II HDMI:Receives one inputsignaland transfersit to X226 in 24 bits.
II Others:Anynet implementation, OpticalPowerPort, USBUpdatePort (notavailablefor MP3)
The L8HDdigitalboardcontainstwo HD tunersto implementanalogas well as digitalsignalsfrom air/cablebroadcasting.
It decodesY PB PR CVBS,Y/C(SUPER) and HDMIinputs usingADV7401and siliconchips,which are transferredto X226(ATI),a
combinationof the mainCPU and the MPEGdecoder.
All video/audio inputsare transferredto X226 for digitalprocessingand all videooutputgoes throughDNle to the DLP DMDboard.
Audio signalsare transferredto the MSPchip of the analog boardusing12Sand are emittedthroughthe speaker.
It also hasan Anynet port,a 5.1 channelopticalportand a USBportfor a S/W update.
