This is a video4linux driver for Conexant 231xx USB based TV cards.
To compile this driver as a module, choose M here: the
module will be called cx231xx

cx231xx hardware has a builtin RX/TX support. However, a few
designs opted to not use it, but, instead, some other hardware.
This module enables the usage of those other hardware, like the
ones used with ISDB-T boards.
On most cases, all you need for IR is mceusb module.

This adds support for DVB cards based on the
Conexant cx231xx chips.
