MAIN SYSTEM(SMP8634) is connected to whole HT-BD2 function IC. For HDMI 1080P, SMP8634 transfer the
digital video signal with 24bit to HDMI TX chip SIL9134. SMP8634 doesn’t need external up scaling IC because it has a
own internal scalar. About it has internal video DAC, so it transfer the analog signal to MM1765, SM5302. MM1765 and
SM5302 are video filter and amp.
Two AUDIO DSP are connected to MAIN SYSTEM. They get the DIGITAL audio signal from main system with bit stream
status. And after decoding the signal, they send the digital signal, which is already decoded, to DIGITAL AMP PWM
driver IC.
MAIN SYSTEM MICOM control SMP8634C, AUDIO DSP MICOM, CEC. He gets all information from SMP8634, and
then transfer the information to AUDIO DSP MICOM. They have a communication among them with HOST ↔ SLAVE
Interface. And MAIN SYSTEM MICOM gets the information from User’s remote control. So whenever he get the
information, he displays it on the VFD.
The loader transfer the source audio, video data to SMP8634.
USB is available but in this generation it is not permitted.
DIGITAL IN 1, 2(SPDIF IN), AUX IN and Tuner IN are each connected to DIR and ADC IC. And then after transforming
DIGITAL SIGNAL(SPDIF IN is DIGITAL signal), the audio signal transfers to AUDIO DSP.
