Consumer expectation when it comes to the viewing experience is often based on watching tier 1 sports productions. In response, sports programmers are searching for solutions that deliver an engaging experience at a cost that is in line with the available budget. Artificial intelligence (AI)-driven sports production solutions have been available for some time. But to date, the ability to accurately track sporting action combined with visual clarity has been a challenge. This article describes how a panoramic camera system can be implemented to monitor the entire field of play, to feed an AI system that identifies the sporting action. Furthermore, how the AI engine can drive a high-quality pan-tilt-zoom (PTZ) camera to follow the action to deliver the program feed is also described. The article also discusses how the AI engine can accurately point the PTZ camera—taking into account video and AI processing delays, how those processing latencies can be measured, to forward-predict directional vectors and correctly point the program feed camera irrespective of distance from the camera and the variation in angular velocity realized.

In recent years, live video-game-centric streaming platforms have experienced dramatic growth, driven by the explosion of the esports market. Besides, live-event rightsholders and broadcasters are successfully “gamifying” their video offerings. Given the rise of video game live streaming, we address, in this article, the questions of how to optimize and adapt the encoding strategies for efficient game content coding. We first characterize game content, focusing on how its signal characteristics differ from “natural” content. We then share insights on selected encoding strategies targeting improvements in both compression efficiency and density/encoder run time for signals with such characteristics. Additionally, we examine the relevance of screen content coding (SCC) tools, as adopted in HEVC SCC and VVC standards, in a video game coding context. Finally, we conclude the article by highlighting the benefits of using game-content-aware technology with better compression efficiency under realtime constraints.

The overall adoption of SMPTE ST 2110 standards and the Advanced Media Workflow Association Networked Media Open Specifications (AMWA NMOS) grows. To serve the industry with a better understanding of these standards and specifications, the Joint Task Force on Networked Media (JT-NM) introduced the JT-NM Tested program. After running the “Tested Program” several times, a number of pain points became clear. These underpinned feedback on the documents and other questions, such as how to improve and scale up this kind of event. To assist with this, SMPTE is creating Protocol Implementation Conformance Statements (PICS) for the ST 2110 standard suite, recommended practice (RP) 2110–25 (Professional Media Over Managed Internet Protocol (IP) Networks: Measurement Practices), and the JT-NM has the JT-NM Tested program. The article outlines the work and the achieved results in the form of PICS documents for the SMPTE ST 2110 standard suite and the RP 2110–25 document to provide for better testing and measurement of SMPTE ST 2110 implementations. We discuss the ways to ensure compliance and interoperability of implementations, including the experience gained during several JT-NM Tested events. We explain how these interop events are operated, the value they bring, and how the PICS will enhance such future events. Another important aspect is monitoring and measuring the implementations’ operation parameters, such as packet pacing. A specific problem discussed is the uniformity and consistency of such measurements among the different SMPTE ST 2110 equipment vendors.
SMPTE ST 2110标准和高级媒体工作流程协会网络媒体开放规范（AMWA NMOS）的整体采用率不断提高。为了更好地理解这些标准和规范，为行业服务，网络媒体联合特遣部队（JT-NM）推出了JT-NM测试计划。在多次运行“测试程序”后，许多痛点变得清晰起来。这些支持了对文件和其他问题的反馈，例如如何改进和扩大这类活动。为了帮助实现这一点，SMPTE正在为ST 2110标准套件创建协议实现一致性声明（PICS），建议实施规程（RP）2110–25（托管互联网协议（IP）网络上的专业媒体：测量实践），JT-NM有JT-NM测试程序。本文以SMPTE ST 2110标准套件的PICS文件和RP 2110–25文件的形式概述了工作和取得的成果，以更好地测试和测量SMPTE ST 211 0的实现。我们讨论了确保实现的合规性和互操作性的方法，包括在几次JT-NM测试事件中获得的经验。我们解释了这些互操作事件是如何操作的，它们带来的价值，以及PICS将如何增强这些未来事件。另一个重要方面是监视和测量实现的操作参数，例如数据包定步。所讨论的具体问题是不同SMPTE ST 2110设备供应商之间的这种测量的一致性和一致性。
