Extensions of High Efficiency Video Coding Standard: an Overview

For extension of High Efficient Video Coding (HEVC), a high quality experience is offered by using three-dimensional (3-D) video. Also, the primary usage scenario for multiview video is to support 3-D video applications, where 3-D depth perception of a visual scene is provided by a 3-D display system. The efficient representation and compression of stereo and multiview video is a central component of any 3-D or multiview system, since it defines the format to be produced, transmitted and displayed. On the other hand, scalable extension of the HEVC standard allows for the scaling of video to different spatial resolution, bit depth, and/or color gamut while maintaining high coding efficiency. In the first part of this article, we deal with 3-D and multiview extensions of HEVC. Coding architecture together with corresponding for the efficient compression is included, too. In the second part, scalable extension of HEVC standard with the migration path from high-definition (HD) to ultra HD is presented.
