Abstract

Super-resolution video coding describes the process of coding video at lower resolution and upsampling the result. This process is included in the AV1 standard, which ensures the same super-resolution process is employed on all receiving devices. Regrettably, the design is limited to horizontal scaling with a maximum scale factor of two. In this paper, we analyze the benefit of enabling two-dimensional upsampling with larger scale factors. Additionally, we consider the value of sending residual information to correct the super-resolution output. Results show a 6.3% and 5.6% improvement in coding efficiency for UHD SDR and UHD HDR content.
