Patent ID: 8004606

Claim:
A method for generating an optimized deinterlaced signal from a deinterlaced input signal, the method comprising: receiving, at a device, a deinterlaced input signal, the deinterlaced input signal having first and second input frames; wherein, each of the first and second input frames includes even scan lines and odd scan lines; identifying a first set of original scan lines in a first input frame of the deinterlaced input signal as one of either the even scan lines or the odd scan lines of the deinterlaced input signal; wherein, in a second input frame which is immediately following the first input frame: even scan lines of the second input frame of the deinterlaced input signal are identified as a second set of original scan lines, if the odd scan lines are selected for the first input frame; odd scan lines of the second input frame of the deinterlaced input signal are identified as the second set of original scan lines if the even scan lines are selected for the first input frame; generating a first optimized frame of the optimized deinterlaced signal using the first set of original scan lines; generating a second optimized frame of the optimized deinterlaced signal using the second set of the original scan lines; wherein the second optimized frame of the optimized deinterlaced signal follows the first optimized frame.
