Actually, it's often done by a combination of interpolation and strobing. The Samsung CMR960 and the Sony Motionflow XR960 actually only quadruples the refresh rate to 240Hz, and then uses 1/960sec scanning backlight (strobing in segments) to get all the way to a "960 equivalence rating". Motion looks really clear (although like exaggerated contrast ratios, it falls short of true "960", and it's not as efficient as newer high-efficiency strobe backlights).to the point of ridiculous HZ rates (1000hz in the newer Samsungs).
The first problem of these "960" TV's a couple years back is the input lag; sometimes almost 100ms worth! The second problem is many of these don't let you turn off interpolation separately from the strobing. It's only recently that, Sony, at least, has finally decoupled the strobing away from the interpolation. This finally lowers input lag of motion clarity enhancement to a total of less than two frames (on the Sony's). This is still improving (LightBoost adds less than one frame average input lag).
