BT8x8 family

The manufacturer of these chips was Brooktree, now Conexant.

In the Linux kernel, they are handled by the bttv driver(s).

If you're mainly interested in the audio features of the bttv chips, see btaudio (bt878).

Some bt878 capture cards have a single chip on board and four inputs on he back of the card. In this case, don't expect multiple input devices. You would have multiple /dev/videoX if you actually had multiple videograbber devices - but you don't. You have one device (the 878A) with multiple inputs, of which only one at a time can be active. This input switching is done by means of the single /dev/videoX API.

SAA713x family

The manufacturer of these chips is Philips.

In the Linux kernel, they are handled by the saa7134 driver(s).

CX2388x family

Also by Conexant, successor of the bt878 design.

Handled by the cx88 driver(s). See Also: cx88 devices (cx2388x)
