A PCI interface chipset from Brooktree that provides video decoder functionality.

It is supported under Linux by the bttv kernel driver module.

Overview/Features

The Bt848 chip was used by many analog cards produced in the mid 1990's; which collectively help constitute the Bttv devices categorization.

Both the Bt848A and Bt849A chip variations included all the features of Bt848 while adding support for a few more functions (summarized in the table below).
