Abstract
A receiver is configured to receive video frames. A cadence detector is in communication with the receiver and is configured to analyze a newly received video frame to determine the cadence of the video frames. A frame rate converter is configured to interpolate at least two of the video frames to form output frames in accordance with an interpolation parameter based on the cadence and with a frequency scaling factor. The frequency scaling factor corresponds to the frame rate of the output frames.
