 From DISC, RF signal is transmited to BACKEND BCM7630. The decoder BCM7630 decodes the RF signal to VIDEO
and AUDIO DATA.
HDMI TX
Analog video signal goes through VIDEO AMP MM1797 and is outputed to COMPONENT(Y,Pb,Pr) and CVBS.
About Digital Video signal, HDMI goes through HDMI TX jack. In case of supporting HDMI IN, HDMI SOC EP94A2K
gets TMDS DATA from BCM7630 and HDMI IN JACK and after packing the data, it sends the data to TX Jack.
HDMI IN 2
HT-C5500 supports 2 USB ports. One is for USB FILE PLAY like MP3, JPG, DivX and etc. The other is for WiFi
wireless LAN.
HDMI IN 1
i-Pod, i-Phone are also supported. About BCM7630 Audio OUTPUT, I2S data goes through DSP TMS320DA788 and
OPTION
HDMI IN
then DSP IC decodes or bypass the data to PWM IC. External AUDIO INPUT also goes throuch DSP TMS320DA788
and then goes through like BCM7630 AUDIO pass. From PWM modulator PS9630B to LPF(Low Pass Filter), DIGTAL
SIGNAL is changed to Analog Signal and amplified by OP-AMP and FET IR AMP.
