Apple hides an ARM chip in the Lightning Digital AV adapter

   ...the Apple Digital Lightning AV adapter was equipped with an ARM
  system chip resting inside the connector at the device end. The SoC is
  complete with 256MB of RAM, which some speculate could be a decoder
  for AirPlay. The secret secret was discovered by the developers at
  Panic Inc. who stumbled on the chip while troubleshooting the device
  in their upcoming project for video-out capabilities.
  [...]
  As far as Panic thinks, the chip could be a convertor or decoder with
  an operating system encoded within. This OS boots up immediately when
  connected, which explains the lengthy startup time for the video
  output through it. The reason for doing so could be due to the
  inability of raw HDMI output from the Lightning connector and the
  possibility of Apple's engineers trying to reduce the cost of the
  equipment with maximum functionality. Hence, someone had to think out
  of the box and put  this tiny computer on an external accessory - and
  hence the Lightning Digital AV adapter.

  The use of a tiny computer chip inside the adapter also explains the
  whopping price tag of Rs 3,500 [~64 USD] for the connector alone.
