{"title":"Can ST 2059-2 Benefit From PTP Version 2.1?","authors":"Nikolaus Kerö;Thomas Kernen","doi":"10.5594/JMI.2023.3306579","DOIUrl":"https://doi.org/10.5594/JMI.2023.3306579","url":null,"abstract":"With the publication of version 2.0 of the IEEE 1588 Standard for accurate time transfer over packet networks in 2008, the Precision Time Protocol (PTP) quickly became the only viable clock synchronization technology for all application domains relying on ethernet as a transport medium. PTP was deliberately defined in highly generic terms, allowing it to be tailored to application-specific requirements via PTP profiles. The SMPTE ST 2059–2 standard is the PTP profile for the broadcasting industry and a crucial element for any all-IP studio deployment. In 2019, the IEEE published a new version of the IEEE 1588 standard (PTP v2.1), where PTP was enhanced with several interesting optional features aimed primarily at improving the overall reliability of PTP, especially for larger deployments. In this article, we explain all major new features of PTP v2.1 and investigate to what extent broadcasting applications may benefit from adopting them as part of a new version of the ST 2059–2 PTP profile. Specific focus will be put on possible implications with respect to implementation efforts and operating requirements. We analyze whether the overall reliability of PTP can be improved by adding new features such as PTP security or extended monitoring. The high-accuracy extensions to PTP v2.1 will be described together with a rough effort estimate required to develop and deploy products supporting subnanosecond accuracy. The article concludes with a list of recommendations summarizing the benefits of these new features for deploying broadcasting networks at scale.","PeriodicalId":49512,"journal":{"name":"SMPTE Motion Imaging Journal","volume":"132 9","pages":"10-19"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49941024","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}

This movement often starts with smaller components such as outside broadcasting (OB) vans and a few studios. Since the advantage of an IP network is connectivity, it is preferable for each of these independently introduced components to be connected and operated as one large program production system that can be shared among many program productions. An NMOS-compliant program-production system has a registration and discovery system (RDS) with information on all equipment in the production system. The challenge is how to configure and operate RDSs when connecting multiple NMOS-compliant systems. To share resources in the system among multiple program productions, it is also imperative that the equipment in operation be protected from accidental operations. To achieve this, a function to manage the operational schedule of each piece of equipment and a mechanism to issue authorizations on the basis of the schedules are needed. The NMOS IS-10 specification defines an authorization method, but there has been no study on issuing authorization on the basis of a schedule managed by a resource administrator. In this presentation, we propose a method for managing multiple RDSs and issuing authorizations on the basis of operational schedules to construct a large program-production system consisting of multiple NMOS-compliant systems. The equipment already in place can be used with the proposed method because the application programming interfaces (APIs) for registration and authorization are the same as those of a standard NMOS-compliant system.","PeriodicalId":49512,"journal":{"name":"SMPTE Motion Imaging Journal","volume":"132 9","pages":"26-31"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49941026","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}

Edge processing overcomes cache limitations by executing compute-intensive tasks at or near edge servers. It is expected to fix some issues related to adaptive bitrate (ABR) over-the-top (OTT) streaming. In particular, just-in-time-transcoding at the edge (JITEX) allows the edge server to cache a single pivot video and to offer nonetheless multiple video versions. This article models the impact of JITEX by examining various cost variables, use cases, and CDN implementation. For the sake of transparency, we use public data and well-known popularity models. By sharing this JITEX model, we aim to facilitate discussion on deploying transcoders at the edge, dispelling misconceptions, and identifying profitable research areas.","PeriodicalId":49512,"journal":{"name":"SMPTE Motion Imaging Journal","volume":"132 9","pages":"32-38"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49941027","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}
