White Paper: Imaging
Back to the Future of Video Encoding
Have you ever seen pixilation, or have noticed face details disappear, confetti in dark areas or simply muddy video? These are negative effects of compression. Compression is needed to enable transport over Ethernet, Internet, Wi-Fi, cable, satellite, and to limit storage size.
A new version of pioneering technology greatly improves image quality, eliminates artifacts and missing details, and greatly reduces latencies; JPEG XS. It is small, fits in an FPGA, uses a transform that yields far superior image quality to that used by H.264/H.265 and introduces very low latency.
This paper discusses the differences between the transforms and shows that H.264/H.265 is not good enough for motion and anomaly behavior study, and professional content. The paper introduces our road map to use JPEG XS to deliver accurate timestamps, collect data in KLV metadata and video all at once while transporting it over GigE or fiber networks.
