Paper Abstract

We describe the real-time CUDA implementation of an error concealment algorithm for high definition video at 720p. The concealment method is based on decoder motion search on high resolution frame, using a thumbnail as a guide, and is therefore comparable in complexity as encoder motion search. We discuss the different requirements for decoder motion search compared to encoder search, and present a fast motion search algorithm suitable for parallel implementation in GPU. The design of the real-time CUDA implementation and its performance analysis are also presented.
