Abstract
High-Throughput JPEG 2000 (HTJ2K) is a royalty-free image compression standard published in 2019 that enhances JPEG 2000 by replacing its slow block coder with a fast block coder. The resulting speedup (e.g., >30× for lossless coding) accelerates the encoding and decoding of images, which can have a great impact on users. A less obvious benefit of the speedup is the enabling of low-latency applications, which was not possible with the original JPEG 2000 standard. Examples of these new potential applications are live, high-quality, low-latency broadcast video contribution, remote production, and Internet Protocol (IP)-based production on-premises and on cloud. This paper examines various HTJ2K encoding parameters and their impact on quality, bitrate, latency, and multigeneration encode/decode cycle performance in the context of requirements of broadcast and IP-based applications. Configurations include a number of different wavelet filters, code-block sizes, and wavelet decomposition structures that are available with HTJ2K. The performance of low-latency HTJ2K is also compared to other low-latency wavelet codecs like VC-2, JPEG XS, and JPEG 2000 Part-1. The JPEG 2000 Part-1 comparisons use the full-frame broadcast profile as well as the ultra-low latency (ULL) configuration as per Video Services Forum (VSF) Technical Recommendation (TR)-01:2018. A tradeoff between latency and compression quality is discussed.

Michael D. Smith
bio
Michael D. Smith has been working as a digital imaging and intellectual property consultant since 2003. He is currently a co-editor of the JPEG 2000 high-throughput image compression standard. In 2018, he received a screen credit for his work on Mary Poppins Returns, which was related to the color science used to integrate a traditional two-dimensional animation workflow with a modern Academy Color Encoding System (ACES) production pipeline. From 2013 to 2015, he was a co-chair of Blu-ray Disc Association’s ultrahigh-definition (UHD)-Task Force (TF) Video Subgroup, which defined the video-related requirements for the UHD Blu-ray disc format. His work on more than 35 intellectual property matters related to infringement and validity of patents has resulted in payments of approximately $1.7 billion. He was an editor of the book “ 3D Cinema and Television Technology: The First 100 Years ” published by SMPTE in 2011. He received BS and MS degrees in electrical engineering from the University of California at Los Angeles (UCLA), Los Angeles, CA, in 2001 and 2004, respectively.
