Gabriel, A. Niamut, O.A. Dijkstra-Soudarissane, S.S. Publication year 2019 Abstract The current state of the art of video coding lacks specific tools to efficiently deal with ultra-high resolutions such as 8K video both at a hardware and software level. At the same time, the increase in video resolutions combined with a larger variety in display resolutions results in a need for spatial scalability at low computational complexity. The proposed solution allows for legacy 4K encoders and decoders both software and in particular hardware to be still exploited with 8K content. The proposed format also offers spatial scalability for an average BD-rate increase of 16%. This scalability is achieved by a polyphase subsampling of the input sequence and by leveraging the existing temporal scalability to induce spatial scalability. © 2018 IEEE.
