dtviic modules provide support for
  dtv(4) devices. The
  dtviic module group includes tuners, demodulators, and
  analog video decoders.
The usual hardware structure consists of a host controller (connected for instance via usb(4) or pci(4)) that provides the data moving facilities (for the analog or digital video streams) and an iic(4) bus over which the other chips can be configured.
For example, a typical dtv(4) setup would look like this:
TS) port on the host
      controller.IF) that is
      provided to it by the associated tuner. This step typically includes
      setting the desired quadrature amplitude modulation
      (QAM) and bandwidth, among other things.DMA transfers or
      USB high speed transfers).The supported demodulators include:
