On-Demand Webinars: Imaging

Back to the Future of Video Compression


Have you ever seen pixilation or noticed face details disappear, frames freeze, confetti in dark areas, or simply muddy video? These are negative effects of compression. Most camera outputs (including cinema) and videos from 720p and up are compressed. Why? Compression is needed to enable transport over ethernet, internet, Wi-Fi, cable, and satellite. It’s also needed to limit storage size. These restrictions have been met in part by compromises in image quality, increased latency, introduction of artifacts, and obliteration of fine details.

This 60-minute Webinar discusses JPEG XS, a pioneering technology that improves image quality, eliminates artifacts and missing details, and greatly reduces latencies.

JPEG2000, the Joint Photographic Experts Group 2000 release, changed encoding from Discrete Cosign Transform (DCT) to Discrete Wavelet Transform (DWT). As compression rises, DWT offers very high image quality and introduces few artifacts and predictable effects. The next generation, JPEG XS, uses advanced DWT and efficient processing. Latency falls below a few milliseconds, while images remain visually lossless up to 20:1 compression. At 20:1, 4K can be carried over ethernet, internet, and Wi-Fi.

In addition to describing the differences between DCT and DWT, the Webinar explains interframe encoding used by H.26x to achieve 1500:1 compression and shows that H.26x is not good enough for scientists, engineers, and professional content creation. It also examines why both bandwidth increases and very low storage costs make it a good time to plan for products based on JPEG XS. Lastly, it looks at using JPEG XS product plans to deliver accurate timestamps, collect data and video all at once, transport it over GigE or fiber network, deliver it with high image quality, and have latencies so low that man-in-the-loop applications are routine.

An audience Q&A follows the technical webinar.
