Abstract:
1. A video processing system comprising: a decoder having a complexity reduction system; and a post-processing system for processing an output of the decoder, wherein the post-processing system includes a filter for intentionally blurring a set of frames in a group of pictures (GOP) to achieve a smooth visual transition between frames, wherein the post-processing system further includes a controller for maintaining a complexity of the post-processing system within a resource budget and for calculating a cut-off frequency of the filter; and a frame selector for selecting the set of frames in the GOP to be blurred by the filter, wherein the controller calculates a number of frames N it is capable of processing for a given resource constraint r according to the equation: N=r/(p·f·k), wherein p is a picture size, f is the filter length, and k is a constant representing a computational resource needed per pixel per filter coefficient.
