Support for BT848 based frame grabber/overlay boards. This includes
the Miro, Hauppauge and STB boards. Please read the material in
<file:Documentation/video4linux/bttv/> for more information.
To compile this driver as a module, choose M here: the
module will be called bttv.
config VIDEO_BT848_DVB
bool "DVB/ATSC Support for bt878 based TV cards"
depends on VIDEO_BT848 && DVB_CORE
select DVB_BT8XX
---help---
This adds support for DVB/ATSC cards based on the BT878 chip.
