A PCI interface chipset from Philips initially intended as a multimedia interface for analog audio and video.
The IC was adjusted to work with DVB by packing the demodulated MPEG-2 Transport Stream data into the video lines of the IC. This hackish approach works surprisingly well in most setups, and only a few have problems with high data loss. A moral formal approach was implemented in the saa7146 chipset's direct successor, the SAA7134, which has a a dedicated digital stream interface.
The SAA7146 is used on a number of older generation DVB cards, such as the Siemens DVB cards, TechnoTrend PCI cards, KNC1 DVB cards and TerraTec DVB cards.
