Apparatus and Methods for Improving Video Quality From a Digital Video Signal Including Replicated Image Frames

摘要

A method includes receiving a first digital video signal having frames at a first frame rate. A respective frame of the first digital video signal is then replicated multiple times to produce a series of replicated frames for inclusion in a second digital video signal have a second frame rate greater that the first frame rate. For at least some of the pixel data defining pixels in at least one of the replicated frames, the method includes randomly modifying the respective pixel data. The random modification of pixel data for a respective pixel in a respective replicated frame results in a modified replicated frame which is included in the second digital video signal.
