5、 HDMI input signal flow
HDMI video signal is sent into main chip MSD209GL to be processed by modules of video decoding,
video processing and zoom, then LVDS signal will be outputted to drive display panel;
HDMI audio signal is sent into main chip MSD209GL for audio processing, preamplification, acoustic
effect processing and volume control, then it is sent to earphone amplifier BH3547F to be amplified,
one is sent to earphone jack, the other is sent to digital audio power amplifier R2A15112 to be
amplified and then drive speakers.
6、 AV input signal flow
Current active AV video signal is sent into main chip MSD209GL for video coding, then it is amplified
by peripheral video amplified circuits and then outputted;
Current active AV audio signal is sent into main chip MSD209GL for preamplification, acoustic effect
processing and volume control, then it is sent to operation amplifier to be amplified and then
outputted.
