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.","PeriodicalId":49512,"journal":{"name":"SMPTE Motion Imaging Journal","volume":"132 10","pages":"6-12"},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138138412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":49512,"journal":{"name":"SMPTE Motion Imaging Journal","volume":"132 9","pages":"39-49"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49941031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":49512,"journal":{"name":"SMPTE Motion Imaging Journal","volume":"132 9","pages":"20-25"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49941025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
