Abstract

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. In this paper we present the transmodality of video stream. Our contribution is a transmoder module that includes various different optimized video codecs and implements the concept of transmodality on a set of video streams. We evaluate our proposal in the context of cloud gaming, using an optimized remote rendering chain and several games. A per game adaptation allows an optimal refinement of video encoding parameters, including both quantization and modality parameters. Our algorithm shows comprehensive results by saving up to 2% of bandwidth for the same PSNR in comparison with the state-of-the-art video encoding baselines.
