Conexant Fusion 878A

An updated version of the former Bt878 chipset (which, upon coming under the Conexant banner, was also sometimes known or referred to as the Fusion Bt878). With the newer Fusion 878A's release, the "Bt" (for Brooktree) was dropped from the product nomenclature.

One of the updates included the adding of support for the handling of MPEG2 TS used by DTV services.

Note: lspci output is slightly misleading in that it identifies the 878A chipset by name of the Bt878 chipset, e.g.:

0000:02:05.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)

However, the Bt878 name should be reserved for the older chips which only supported analog applications and lacked facilities for digital TV applications. In otherwords, if you have a 878-based digitalTV device, you can be certain that the chip is actually the Fusion 878A, and not the older Bt878
