Abstract
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.
Claims21
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.
A method for eliminating prediction drift in a complexity reduced video sequence, the method comprising:
- determining an amount of post-processing resources available;
- determining a number of frames in the video sequence that can be processed pursuant to the available resources;
- selecting a set of frames within the video sequence to process;
- and
- filtering the set of selected frame, wherein the filtering blurs the set of frames in order to achieve a smooth visual transition between frames.

A post-processing system for eliminating prediction drift in a complexity reduced video sequence, comprising:
- a controller for receiving an available amount of post-processing resources and determining a number of frames in the video sequence that can be processed pursuant to the available resources;
- a frame selector for selecting a set of frames within the video sequence to process;
- and
- a filter for filtering the set of frames, wherein the filtering blurs the set of frames in order to achieve a smooth visual transition between frames.
