Digital Signal Processor Explanation

The main function of the A board is to select and process one of the incoming video signals. Analog signal from Video
inputs 1 and 2, Component Inputs 1 and 2, PC input, and the composite video output of the tuner are all connected to
IC3001 for selection. The video output signal, (Y, Pb, Pr) enters the PEAKS LDA2 IC (IC8000) for processing.
The digital signal from the 4 HDMI ports is also provided to IC8000. Only HDMI is ARC (Audio Return Channel)
compatible.
The data from HDMI 1 and HDMI2 are connected to an Equalizer to allow for longer cables to be connected to these 2
ports.
USB data, Ethernet data, and JPEG data of the SD card are also connected to IC8000.
All picture control operations such as brightness, contrast, color, tint, etc are performed by IC8000. On Screen Display
data such as channel numbers, Digital TV closed caption, and picture adjustments are mixed with the video data. The
signal is then converted LVDS (Low Voltage Differential Signaling).
The LVDS data from IC8000 enters the MIHO-3D (IC5800). IC5800 separates the LVDS data into right LVDS and left
LVDS and also outputs the IR synchronizing signal to the eyewear.
The Right and Left LVDS data is then output to the D board.
