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
Sys-MICOM Switching Control
SPDIF IN 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.
