Patent ID: 8565309

Claim:
A method of operating a digital video system comprising: identifying a plurality of candidate motion vectors indicative of differences between first and second frames of a digital video signal; projecting each of the candidate motion vectors to a location within a third frame at a time associated with the third frame; determining a count of the candidate motion vectors passing through the location within the third frame; determining a measure of overlap of each projected location with a portion of the third frame to be interpolated; selecting at least one motion vector based on the measure; and generating at least a portion of a third frame based on a reliability associated with each of the selected at least one motion vector; wherein selecting the at least one motion vector includes selecting: a first motion vector having the highest measure of overlap from the candidate motion vectors and the immediately neighboring motion vectors of the first motion vector; and a second motion vector having the second highest measure of overlap from the candidate motion vectors and the immediately neighboring motion vectors of the second motion vector.
