Abstract

In this paper we present RDVideo, a new lossless video codec based on Relative Distance Algorithm. The peculiar characteristics of our method make it particularly suitable for compressing screen video recordings. In this field its compression ratio is similar and often greater to that of the other algorithms of the same category. Additionally its high degree of parallelism allowed us to develop an efficient implementation on graphic hardware, using the Nvidia CUDA architecture, able to significantly reduce the computational time.
