      Abstract: We are now weary of any prognostications of what the new year will bring in business or personal life. When we thought the pandemic was behind us, we discovered it was actually in a relay and handed off the baton to economic uncertainty and inflation. I am not quite sure why this surprises any of us. Change is the only constant, as the saying goes.

      Pages: 7 - 9
      Abstract: As SMPTE moves into 2023, Renard Jenkins advances into the role of SMPTE president, becoming the first African American to serve in that role over the organization’s 100-year history. He jokes that things have come full circle over the past century, from one Jenkins to another. (SMPTE was founded in 1916 by Charles Frances Jenkins.) But for Jenkins himself (Renard, that is), the path has been anything but circular. He has long had a passion for creative technology, and it did not take long for him to find his way into the world of media and entertainment.

  • 5G-MAG (Media Action Group) Reference Tools: Putting 5G in Action for
           Media

      Pages: 18 - 24
      Abstract: Content providers are increasingly using the internet to deliver content to users. Users can also enjoy this content on a wide variety of devices anywhere and at any time. The increasing consumption of high-quality mobile video over 5G networks is set to demand sophisticated and robust streaming service architectures and implementations ready to cope with traffic loads and meet the requirements and expectations of content owners. The ongoing standardization of 5G is an opportunity to provide the media industry with the right tools to operate the 5G media platform. With this in mind, 5G-MAG (Media Action Group) has kickstarted the 5G-MAG reference tools project to develop common open-source reference tools to support the implementation and interoperability of 5G media technologies. In this paper, we present the current architecture of the 5G-MAG reference tools implementing client components in the context of 3rd Generation Partnership Project (3GPP) release 16 5G media streaming and 5G broadcast. Moreover, we provide detailed insights on the first two use cases “Long-Term Evolution (LTE)-based 5G Broadcast” and “broadband-broadcast seamless switching” and give an outlook on future work on use cases such as “targeted ad-insertion” and “regional content insertion.” We also show how the tools serve as a reference or integration platform for traditional broadcast networks and services including a DVB-I service layer or the alignment with the service layer of ATSC 3.0.

  • Supporting Live Production Using Precision Time Protocol Over 5G Systems
           With Dedicated Time Synchronization Support

    • Free pre-print version: Loading...

      Authors: Ievgen Kostiukevych;Mohamed Nabil Ibrahim;Pavlo Kondratenko;Thomas Kernen;Thorsten Lohmar;
      Pages: 25 - 39
      Abstract: The article explores the possibility of using IEEE 1588 Precision Time Protocol (PTP) over a 5G system for media production applications. The article describes lab sessions performed by the 5G RECORDS consortium members, testing the performance of PTP over 5G with and without the dedicated time synchronization support. A trial with a real camera supporting SMPTE ST 2110–22 with JPEG- XS was conducted to experiment with synchronization and packet pacing precision. The 5G system used in these experiments features additional functionalities from the 3rd Generation Partnership Program (3GPP) Release 16, including specific time synchronization support for time-sensitive networks (TSNs), that is, acting as a time-aware system, and Release 17 in which the support for IEEE 1588 is extended with several additional features. The article also describes the testing setup based on the open-source software used by the team and the methodology developed. The article concludes on the performance and synchronization quality when using PTP over various 5G systems and analyzes the results from the lab trials. This new approach with the experimental setup allows using PTP according to the SMPTE ST 2059–2 PTP profile reliably over 5G for media device synchronization, which is not usually done in the context of the 5G networks.

  • Optimized Camera Integration in IP-Based Workflows and Infrastructures

    • Free pre-print version: Loading...

      Authors: Klaus Weber;
      Pages: 40 - 46
      Abstract: The increasing availability of powerful IP infrastructures opens up new application possibilities for system cameras in media and entertainment applications. Additional IP interfaces on camera base stations have enabled initial applications to be covered and experience to be gained in the first step. However, the question arises as to how the integration of cameras in IP infrastructures can be optimized in such a way that an improved workflow can be achieved for almost all use cases. This includes the possibility of adapting the bandwidth requirements of the cameras to the existing IP bandwidths, but also the possibility to do this without external conversion of the video signals to IP signals. This article will highlight the various challenges and present possible solutions based on camera systems with fully integrated IP connectivity.

  • Synchronized Multistream Transport Using RIST

    • Free pre-print version: Loading...

      Authors: Ciro A. Noronha;
      Pages: 47 - 53
      Abstract: Many broadcast contribution applications require synchronized content decoding. In such applications, there are several video sources (typically cameras), whose content needs to be transported using encoders to an equivalent number of remote decoders. At the decoders, the playback needs to be synchronized—frames that arrive together at the encoders are required to come out together at the decoders. Typical applications are sports and worship, where multiple camera angles are generated and need to be played in lockstep. There are a few products available today in the market that provide such functionality over IP, using proprietary protocols. The Reliable Internet Stream Transport (RIST) Activity Group (AG) is completing the work on an open industry specification for providing synchronized multistream transport. This article provides a technical description of the methods in the specification, as well as some actual field performance data.

  • An ST 2110 Network-Attached Display Adapter for Virtualizing Production

    • Free pre-print version: Loading...

      Authors: Thomas True;
      Pages: 54 - 58
      Abstract: Graphics processing unit (GPU) installations in post-production and broadcast facilities require video to be sent remotely conforming to the SMPTE ST 2110 standards for plug-and-play device connectivity. Furthermore, in such facilities, workstations are now being virtualized and hosted in the data center with what would have previously been a physically attached serial digital video (SDI) reference display replaced by an Internet Protocol (IP) network connection. We present a SMPTE ST 2110 virtual network-attached reference display adapter using commercial off-the-shelf (COTS) hardware that presents the GPU and network interface card (NIC) as a display on the computer workstation desktop. Color-accurate rendered video frames are transmitted directly from GPU device memory. Alignment of the GPU display of the rendered frame and the synchronization of the audio, video, and ancillary data streams are maintained by precision time protocol (PTP). Advanced Media Workflow Association Networked Media Open Specifications (AMWA NMOS) integration permits the discovery and registration of the virtual network-attached reference display adapter as a source node on the media network such that it can be remotely managed and controlled by software greatly simplifying the administration compared with a physically connected display and associated cables. Content creation applications send ST 2110-compliant video, audio, and ancillary data flows on the media network from a virtualized computer workstation desktop without the cost of directly integrating ST 2110 transmission capabilities.

  • Tighter NIC/GPU Integration Yields Next-Level Media Processing Performance

    • Free pre-print version: Loading...

      Authors: Thomas Kernen;Thomas True;
      Pages: 59 - 68
      Abstract: As the media industry further consolidates building services based on commercial-off-the-shelf (COTS) hardware, the requirement for increasing performance continues to accelerate. The processing of video resolutions up to ultra-high definition (HD) (UHD) and 8K, higher frame rates, increased bit depth, and high-dynamic-range (HDR) imagery requires tighter integration and optimization between the network interface controller (NIC) and the graphical processing unit (GPU). Combined with simultaneous input and output of multiple streams; this creates the potential for performance bottlenecks that must be unlocked. This article describes how COTS hardware platforms running Graphics Processing Unit (GPU)s alongside ST 2059–2 Precision Time Protocol (PTP) locked Network Interface Cards (NIC)s, which are accurately pacing packets according to ST 2110–21 requirements, may further increase their performance throughput by reducing central processing unit (CPU)-driven data copy overhead and, in doing so, they reduce processing latency and jitter as well as more effectively use GPU resources while freeing up CPU resources.
