SyncDet(FPGA)
The TMDS signal which is input to the HDMI terminal is transmitted to the HDMI
Receiver IC (IC2203) and converted to RGB 10-bit digital video signals, clock
signal, horizontal/vertical sync signal, DE signal, and FIELD signal, then input to
SyncDet (IC2803).
In addition, the audio signal is converted to Master Clock (MCLK), Bit Clock
(BCLK), Word Clock (WCLK), and Data (DO), then input to SyncDet.
This Receiver IC is equipped with a HDCP function. If the video output device is
also equipped with a HDCP function, the encryption unlock is processed
between the video output device and the Receiver IC, and when encryption is
unlocked, the device can output the video. If not unlocked, the video will not be
output.
Also, the Receiver IC has a built-in memory area for EDID.
