2. Audio signal processing
The audio signal embedded into an SDI signal is decoded using IC5000. The audio signal embedded into
an HDMI signal is decoded using IC2003. One signal is selected out of these two kinds of digital signals
and an analog audio signal from AUDIO IN terminal, and sent to an analog output terminal, speaker
output terminal, and then headphone output terminal.
3. CPU
The CPU of this unit is mounted in IC6000. Each device is set and controlled by the user control and
parallel remote control from an H1 board, the control from LAN, and the value that a panel temperature
sensor detects.
Connection buses are as shown below.
