A new JPEG XS profile for lightweight, low-latency
coding of video, graphics and desktop content.
Tim Bruylants – intoPIX
Synopsis: A revision of the JPEG XS standard (ISO/IEC 21122) adding new coding tools based on intoPIX's proven technologies for the efficient coding of video sequences is coming. The upcoming 3rd edition will add a new profile to drastically improve the video compression efficiency, especially for graphics and complex desktop content sequences, while still preserving the main unique features of JPEG XS: lightweight fast compression, with low latency, and visually lossless quality. Experiments showed significantly improved compression ratios (around a factor of two) while delivering the same visually lossless quality as the XS High profile. The new profile will allow to support new use cases in media and AV workflows. The expected publication of the 3rd edition of JPEG XS is for the beginning of 2024. Finally, the new profile will natively include support for the current JPEG XS Main and High profiles, ensuring a safe and compatible upgrade path for existing JPEG XS ecosystem!
This presentation will talk about the ongoing standardization activity of JPEG XS and explain the new coding tools and the technical improvements it will bring regarding compression performance.
Why No Reference Metrics for Image and Video Quality
Lack Accuracy and Reproducibility
Margaret H Pinson – US Department of Commerce, Institute for Telecommunication Sciences
Synopsis: Most of my proposed presentation would summarize my IEEE Journal article of the same name (https://ieeexplore.ieee.org/document/9837932). I will provide a comprehensive overview of no reference (NR) metrics for image quality analysis (IQA) and video quality analysis (VQA). We examine 26 independent evaluations of NR metrics (previously published) and analyze 32 NR metrics on six IQA datasets and six VQA datasets (new results). Where NR metric developers claim Pearson correlation values between 0.66 and 0.99, our measurements range from 0.0 to 0.63. None of the NR metrics we analyzed are accurate enough to be deployed by industry. Performance evaluations that indicate otherwise are based on insufficient.
Also, I will explain what NR metrics could do for video service providers (if they were accurate enough for commercial deployment). I will end with a call for action. Attendees could increase the likelihood that researchers will develop accurate NR metrics at some point in the future. In a nutshell, academia needs a lot more training data. There is a particularly strong need for datasets that have broadcast content and depict impairments that matter to VSF.
Providing Quality of Service over 5G connectivity for live IP media production – the control plane unpacked.
Andy Rayner - Nevion
Synopsis: This presentation will look at the potential and challenges of 5G technology for IP production and the (very) recent testing of some new approaches in manipulating the control plane to provide deterministic QoS capability.
Most current 5G media transports rely on techniques in the data plane to attempt to provide deterministic performance over inherently best efforts connectivity.
The approach explored in recent testing utilizes interfacing in the 5G control plane to control traffic flows and expedite critical flows.
There will be some pictures and video from behind the scenes at the UK King’s coronation in early May where these techniques were recently put through their paces.
