Abstract
Official abstract text for this publication.
A method for encoding a video stream includes partitioning the video stream into a main layer having a plurality of main layer frames, and an interpolated layer having a plurality of interpolated layer frames; interpolating a frame rate up conversion (FRUC) frame; and encoding the plurality of main layer frames in the interpolated layer with the assistance of the main FRUC frame. A video encoder implementing the method is also described.
First claim
Opening claim text (preview).
What is claimed is: 1. A video-encoder processor for encoding a video stream having a plurality of frames, the video encoder processor comprising: a frame rate-up-conversion (FRUC) module, the FRUC module generating a FRUC frame with reference to a first frame of the video stream; a rate distortion cost (RD_cost) calculation module coupled to the FRUC module and configured to: receive the FRUC frame and calculate a first cost based on a macroblock of the FRUC frame, wherein the…
