1. A video signal frame rate modifying assembly for modifying a frame rate of a native video signal for use in a stereo display system, the native video signal containing alternating left and right eye images, comprising:
- a clock signal generator for generating a clock signal, the clock signal having a frequency of a desired frame rate for an output video signal of the video signal frame rate modifying assembly; and
a video encoder for receiving the native video signal and increasing a frame rate of the native video signal to the desired frame rate based on the clock signal, the increased frame rate video signal output as the output video signal.

Abstract
A assembly that modifies the frame rate of a 3D video signal and corresponding method are disclosed. The frame rate of the video signal can be increased by clocking a video encoder at a desired clock rate. When viewing a display of the video signal with the increased frame rate through a pair of stereo glasses, the perception of flicker can be reduced or eliminated.
