Post-processor design supporting non-flickering interlaced display

Abstract

Disclosed herein is a method and apparatus for preventing and eliminating undesirable effects in displayed video. The method may include receiving video information and decoding the video information. The method may also include processing the number of illuminable lines associated with a video frame and blanking a remainder of the illuminable lines. Blanking the remainder of the illuminable lines may prevent and eliminate undesirable effects in the displayed video. The illuminable lines may be processed, such that each field may comprise an even number of corresponding, illuminable lines 530. The fields, however, are not required to have the same number of lines. In an embodiment according to the present invention, no active lines in one field may be below a blanked line in a corresponding field. The apparatus may include a video processor including a video post-processing unit adapted to determine a number lines to be illuminated on a particular video display device and a number of lines to be blanked in order to prevent and eliminate undesirable effects in the displayed video.
