Today’s broadcast video content is being viewed on the widest range of display devices ever known, from small phone screens and legacy SD TV sets to enormous 4K and 8K UHDTV displays. The growth in size and resolution is happening alongside many other improvements, in grey-scale resolution, colorimetry, 3D and, especially, higher frame rates.
These developments mean that the requirements for very high quality, artefact-free conversion in resolution and frame rate have become more important than ever. The challenge is given a further dimension by the wider range of content that can appear on large screens, from upconverted archive footage to the much more detailed, wider window on the world made possible by the new large formats.
This paper presents cutting-edge algorithms for motion compensated processing to meet these challenges in both live TV and file-based operation. One size no longer fits all, so this paper also discusses how to achieve a balance across the range of processing complexity and performance, showing how the trade-offs can be managed gracefully and optimally.
