Video Stream Transmodality

Abstract

In this paper we introduce the concept of video stream transmodality. Transmodality is the partitioning of an image into regions that are expected to present a better entropy using different coding schemes, depending on their structural density, at constant bandwidth. Our contribution is a transmoder i.e. an algorithm able to perform transmodality on a video stream. The transmoder includes different video coding adapted optimizations. We evaluate our proposal with different kinds of video (in content term), and we show that we are able to save up to 8% of bandwidth for the same PSNR in comparison with state of the art video encoding baselines.
