These cards, currently the [[Hauppauge PVR-250]] and [[Hauppauge PVR-350]] and the [[AVerMedia M179]], 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.

Like the Analog Hardware-MPEG cards above, these cards have a video processor onboard which compresses the tuned video signal into an [[MPEG-2]] [[program stream]] before sending it into the computer.  One example of such a card is the [[AVerMedia DVB-T 771]].
