Combined scalable and mutiview extension of High Efficiency Video Coding (HEVC)

Abstract

The scalable and multiview extension of High Efficiency Video Coding (HEVC) is being designed to support scalable layers and multiple views at the same time. Applications of the combined scalable and multiview HEVC coding include scalable stereoscopic video (e.g. 1080p stereo to the emerging 4K stereo), mixed resolution multiview coding, etc. However, there has been no prior work on the coding efficiency of the combined scalable and multiview HEVC coding. In this paper, the scalable multiview HEVC codec is developed based on the scalable HEVC reference software and the performances of inter-layer prediction and inter-view prediction are evaluated in the scalable stereo coding application. Two scalable HEVC coding frameworks, namely TextureRL and RefIdx, are compared as well in the same application.
