Compiling a driver

Not really on topic, but I am trying to get a DVB/DAB USB stick working (EzCap brand with Realtek RTL2832U chip).
I need to merge the V4L-DVB Source with the driver, and one of the lines of instruction from LinuxTV (Here:), is: make tar DIR=<some dir with media -git tree>
Anybody fill me in on what <some dir with media -git tree> means?
Thanks, John.
