DESCRIPTION
# MAIN SYSTEM (BCM7440P) is connected to whole
HT-BD1250 function IC. For HDMI 1080P, BCM7440P transfer the digital video signal with 24bit to HDMI TX chip SIL9134. BCM7440P 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 MM1757, BCM7440P.
MM1757 are video filter and amp.
MM1757 are video filter and amp.
# AUDIO
DSP (TM320D788) is 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 BCM7440P, AUDIO DSP MICOM, CEC. He gets all information from BCM7440P, 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 BCM7440P.
# Both of USB are available, but front USB is for LOCAL STORAGE of PROFILE 1.1/2.0 and USB HOST function, whire Rear USB is for wireless LAN Dongle.
# 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.
