| 5:30 PM - 6:00 PM | Software and IP technologies have revolutionized live event broadcasting over the past decade. However, evolving media consumption habits have outstripped the capabilities of traditional hardware-centric broadcast infrastructures. Broadcasters face increased market fragmentation and pressure to produce more content with fewer resources. IT and cloud computing innovations offer promising solutions but transitioning from hardware to IT-based architectures poses challenges. Unlike broadcast's clock-driven real-time synchronization, IT equipment operates asynchronously, necessitating a shift in how live video is managed. This paper explores a new paradigm in software-based broadcast infrastructure, capable of bridging broadcast and IT domains while meeting high broadcast standards. It will cover: Synchronous vs. asynchronous operations System architecture, including framework design, media microservices, timing, and application control Empirical data showing time savings from asynchronous processing Benefits for live production, such as scalability, reliability, agility, and composability | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| 3:00 PM - 3:30 PM | This panel discussion addresses the evolving landscape of color grading and color science, focusing on preserving the craft's richness amid contemporary homogenization trends. As visual styles increasingly converge, there's a risk of losing the nuanced diversity and historical context that have long defined color grading. The panel will explore strategies to bridge generational gaps, emphasizing education, mentorship, and interdisciplinary collaboration to maintain and enhance the unique visual qualities of color grading from film to digital formats. Through anecdotal cases and theoretical color science pipelines, the discussion will highlight how blending technological advancements with traditional aesthetic principles can sustain visual distinctiveness. Attendees will gain insights into creating color grading practices that balance innovation with heritage, ensuring that future films and television shows retain their unique visual impact. The goal is to empower colorists and color scientists to craft compelling visual experiences that resonate with audiences while honoring the craft's legacy.  | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 5:00 PM - 5:30 PM | This case study explores the transition of The Eurovision Song Contest's video system from traditional SDI to the SMPTE ST 2110 standard, showcasing its advantages for large-scale live events. Eurovision, a hybrid of arena-sized live performance and broadcast show, upgraded to ST 2110 over a 100Gb dual redundant backbone. The transition addressed challenges unique to its production, such as managing vast amounts of content for 37 delegations and transporting it to LED screens and display devices. ST 2110's robust network-based infrastructure supports large-scale, high-redundancy systems, reducing potential delays and points of failure compared to SDI. This study highlights Eurovision’s successful migration, illustrating how other live events can leverage ST 2110 for enhanced performance and reliability. Attendees will gain insights into the benefits of network-based solutions for large LED display systems and how to apply these learnings to future productions. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 5:30 PM - 6:00 PM | Broadcasters are increasingly adopting IP infrastructure to enhance live sports coverage with HDR video and immersive audio. The publication of ST 2110-41 (Fast Metadata Framework) has streamlined real-time IP-based metadata workflows, supporting Dolby Vision and Dolby Atmos in live linear services. Ateme, Dolby, and Jünger Audio are leveraging ST 2110-based systems to enable end-to-end metadata communication, driving Dolby Vision, Atmos, and AC-4 distribution. ST 2110-41 facilitates the transmission of HDR video and Next Generation Audio (NGA) metadata through S-ADM (serialized Audio Definition Model) from live sources to encoders, automating workflows for ATSC 1.0/DVB and advanced ATSC 3.0/DVB-T2 use cases. France TV will use this during the Olympics 2024, and major European broadcasters will soon offer UHD Dolby Vision and Atmos services. In North America, ATSC 3.0 services will also benefit. This integration ensures precise HDR video and customizable audio experiences, simplifies UHD signal flow, and enhances scalability.  | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| 3:00 PM - 3:30 PM | Sky Sports launched its live HDR service for English Premier League football in August 2022, expanding to over 6000 hours of UHD HDR sport production across multiple platforms. This paper explores the end-to-end considerations for integrating live HDR while maintaining HD delivery. It details the choice of Hybrid Log-Gamma (HLG) for HDR broadcasts and how Sky uses a single UHD and HD workflow to deliver HDR and Wide Color Gamut (WCG) benefits cost-effectively. The paper examines the impact of HDR and WCG across different sports, the necessity of UHD for HDR, and the operational demands, including training for engineers. Key areas covered include the design of workflows for editing, archiving, and encoding, as well as LUT-based conversions and broadcast graphics workflows. Additionally, the paper discusses critical viewing and management of end devices in assessment environments. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 5:00 PM - 5:30 PM | Vector-based image search technology, which encodes images and queries as vectors in a high-dimensional space, is increasingly used for efficient image retrieval. This approach involves several key steps: extracting embeddings through convolutional neural networks, developing an indexing workflow that includes preprocessing, extracting, and compressing these embeddings, and inserting them into a searchable index. The search engine utilizes approximate nearest neighbor search (ANNS) and compression methods to enhance efficiency. Traditionally, search engine optimization for images relies on keywords either embedded in metadata or placed on hosting pages. However, vector-based searches face challenges in adaptively enhancing image discoverability due to the static nature of image vectors. This paper introduces a novel method to optimize image discoverability for vector-based search engines while minimizing visual impact. The approach frames the problem as an optimization task, using an iterative process to adjust images based on intended and unwanted search queries. It employs backward propagation with loss functions to fine-tune images, generating embeddings that align with target queries and minimizing visual deviations through perceptual loss. Segmentation masks can further direct visual adjustments to specific areas of an image. This technique can be applied to newly uploaded images or existing asset libraries to improve search ranking.    | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
