Detailed Description

Deinterlace frames using the "bob" method.

In short, the "bob" method separates the top and bottom half-frames, rescales each of them up to full size, and then displays a video stream at double the normal rate. It is named "bob" for the slight bobbing up and down that may occur due to the one-pixel vertical offset between the top and bottom half frames; however in practice this bobbing usually imperceptible.

See http://en.wikipedia.org/wiki/Deinterlacing and http://www.100fps.com/ and for lots of information on various deinterlacing methods.
