How is a base rig capable in extracting the parachute in the limited distance that it has to open and with the limited velocity that the jumper has upon opening?

Most base rigs are a 2 pin system. One near the top, 1 near the bottom.
Containers are generally smaller in size, but mostly stick off your back less. More aerodynamic for tracking/WS and less bulk.
Container flaps close in a different order and are designed to open in a different order/sequence.
There is no D-bag to hold the chute when packing it.
Risers/Canopies are designed to have slight control while opening to keep on heading.
More accurate/on heading openings. The wall/object is not your friend and you want to get away from it as far and fast as possible (generally speaking). There is proxy flying, but you still want to deploy well away from the wall and facing away.
Canopies can be packed differently, for faster deployment and greater reliability/consistency.
There can be slider down or removed for subterminal jumps, generally no greater than ~4 second delays.
They open faster and more accurate/on heading
Pilot Chutes come in various different sizes (as do skydiving) but people tend to change them up a more depending the on object/height. There is vented/non vented PC's (same with skydiving) but can be more critical because oscillation of the pilot chute can contribute to off-heading openings.
No cutaway handles.
Also, never heard of an AAD on a base rig.

Go to Basejumper.com and just read whatever you can

It's more related to the size of the PC, and the design and pack job of the canopy.
You have to realize that the skydiving system you jump today is the result of years of development tyring to make mains open slow and reliably deploy at terminal. If you were to design a system for only subterminal jumps, it would be different than you see now. If you wanted a canopy that opens in 100ft and not 500ft, again, it would be different than the equipment you use now.
Different jobs require different tools, it's that simple. Seriously, if you have questions about BASE jumping, click on the words 'base jumping', and it will take you where you need to be.

as dave said the bigger pilot chute is key, but more so as a way to initiate the deployment sequence at a much slower airspeed. on top of the size of the pilot chute, the way the pilot chute is packed is much different than the way a skydiving pc is packed. also the freepacking and freestowing of the canopy and lines and the lack of a slider all contribute to a faster opening. on longer delays a slider made out of mesh material can be used to slow the opening down to a more comfortable level while still being pretty brisk.
