13-2-2 Digital Board Block Description
■
Select Sound/Video
One is selected from multiple inputs by the switching ID. MICOM decides which port is used for output.
For broadcasting signals, sub-outputs are transferred in CVBS and, the main outputs in Y/C through the 3D Comb, to the digital
board.
Sound signals are selected by the switching IC, of which only one input is transferred to the speaker.
■
Detection Signal Flow
When each port is connected to a signal cable, the detection signal is "low" and can be checked by Micom scanning.
■
CXD3815: Analog YPBPR, CVBS, Y/C(SUPER), Input MUXING and Video Decoding
■
S5H2201: CPU, + MPEG Decoder, Audio signals transferred to MSP of the analog board by I2S
■
Tuner: Main-HD Tuner,Sub-Analog Tuner
■
HDMI: Receives Two input signal and transfers it to S5H2201.
■
Others: Anynet implementation, Optical Power Port, USB Update Port (not available for MP3)
