LVDS Connector

HDMI transmitter reads the HDCP certification and EDID information when connected to the HDMI connector (P505).
At this time, if the HDCP certification fails or if the EDID information cannot be read, the HDMI transmitter does not
send out the video and audio signal.
When HDCP certification is successfully done, the signal sent by the transmitter that could not read the 
EDID information is decoded by the DTV controller(IC401) and converted to LVDS signal to be sent to the 
LCD panel through the LVDS connector.
The DVI transmitter only outputs the video signal after HDCP certification and reading the EDID information.
(For DVI transmitter, the PC generally outputs the video signal after HDCP certification and reading 

the EDID information, but if the Set Top Box is the DVI transmitter, sometimes it outputs only the video signal 
unconditionally in set resolution.)

The signal received through IC401 is shown in the display through the same process as above.
