Abstract
A deinterlacing apparatus includes a buffer to receive a plurality of consecutive fields of an interlaced video and a field combination module coupled to the buffer to deinterlace the interlaced video in accordance with cadence of the interlaced video. The deinterlacing apparatus also includes a cadence detection module to detect the cadence by (1) causing each of the fields to be combined with its preceding field into a frame and with its subsequent field into another frame to obtain a plurality of combined frames, (2) determining a comb factor of each of the combined frames to obtain a sequence of comb factors of the combined frames, and (3) determining if the sequence of comb factors of the combined frames follows a pre-determined repeating pattern. A cadence detection method is also described.
