Abstract: Systems and methods are provided for converting an interlaced video to a slower video rate. A method for video rate conversion may include receiving an input interlaced video having a field rate, and deinterlacing the input interlaced video at the field rate to produce a first sequence of frames corresponding to a first frame rate. The method may also include dropping frames from the first sequence of frames to produce a second sequence of frames corresponding to a second frame rate, wherein the second frame rate is slower than the first frame rate. If a progressive video output is desired, then the second sequence of frames may be used for the progressive video output. If an interlaced video output is desired, then the second sequence of frames may be interlaced into a sequence of fields corresponding to a field rate slower than the field rate of the input interlaced video.
