description:
  The ADV7481 and ADV7482 are multi format video decoders with an integrated
  HDMI receiver. They can output CSI-2 on two independent outputs TXA and TXB
  from three input sources HDMI, analog and TTL.

    description:
      The ADV748x has up to twelve 256-byte maps that can be accessed via the
      main I2C ports. Each map has it own I2C address and acts as a standard
      slave device on the I2C bus. The main address is mandatory, others are
      optional and remain at default values if not specified.
