A video decoder for PCI applications from Brooktree that was used by many analog cards produced in the mid 1990's.
The Bt848A and Bt849A variations both included all the features of Bt848 while adding support for a few more functions (summarized in the table below).
The Bt848 would also become the basis for several other successive decoder chipsets, beginning with the Brooktree Bt878; which themselves would also prove to be widely utilized.
