The ADV7180 is an integrated video decoder that automatically detects
and converts a standard analog baseband television signal (NTSC, PAL,
and SECAM) into 4:2:2 component video data compatible with 8-bit
CCIR601/CCIR656. The ADV7180 is compatible with a broad range of
video devices, including DVD players, tape-based sources, broadcast
sources, and security/surveillance cameras.
The registers in the Video decoder can be programmed by a serial I2C bus,
which is connected to the HSMC connector as indicated in schematic.
