Tuner Cards currently (Aug 04) come in several types:

* Analog framebuffer cards

These cards are usually based on a [[chipset]] like the [[bttv|Bt848/878]] or Conexant cx38882, and decode broadcast [[NTSC]], [[PAL]], or [[Secam]] television.

* Analog Hardware-MPEG cards

These cards, currently the Hauppauge [[PVR-250]] and [[PVR-350]] and the [[[[A Ver Media]] M-179]], have a video processor onboard which compresses the tuned video signal into an [[MPEG-2]] [[program stream]] before sending it into the computer.  The tends to greatly reduce the load on the entire machine (with certain technical [[caveats]]), and these cards are recommended for.. well for all systems, really, but specifically, for systems with more than one, and especially more than 2 tuner cards.
