"AES and AIMS are collaborating once again, to present the 2019 Audio/Video-over-IP Technology Pavilion, designed to offer visitors valuable insights and practical knowledge about audio and video over IP networking. And this year, we've expanded the scope of the pavilion to include video and other related professional media networking topics," says Terry Holton, AIMS Audio Group chairman. "Presenters ranging from industry associations and solutions providers to end users and technology developers will share their knowledge and perspectives on the latest developments in audio and video over IP technologies and deployments. Presentations are open to all AES attendees, as well as attendees to the NAB NY Show, which runs in parallel to the AES Convention. The presentations will provide a great learning opportunity for pro audio, broadcast, and pro AV professionals as they transition their operations and businesses to IP."
The 2019 Audio/Video-over-IP Technology Pavilion Theater presentations will address 20 topics and include technical tutorials, real-world case studies, market/business case analyses, point-of-view/advocacy, and updates on the progress of audio and video over IP standards. Covered technologies will range from AES67 and the SMPTE ST 2110 suite for Professional Media Over Managed IP Networks to AMWA NMOS specifications, timing and synchronization using SMPTE ST 2059, and the emerging JT-NM TR-1001-1 framework for installing, configuring, and interconnecting equipment.
IP Standards Roadmap
The AES presentations will occur at an important moment, since the Alliance for IP Media Solutions (AIMS) recently released an important update to the AIMS roadmap for a standards-based approach to applying IP technologies, now including the JT-NM TR-1001-1 set of specifications, also known as the JT-NM Tech Stack Part 1.
Developed by the Joint Task Force on Networked Media (JT-NM) to automate installation and eliminate complexity, JT-NM TR-1001-1 provides specifications and guidance designed to make SMPTE ST 2110-based systems easier to deploy and operate, leading to greater efficiencies for broadcasters and large installations.
The addition of the JT-NM Tech Stack Part 1 to the AIMS roadmap is the latest in a progression of IP-based standards that launched with SMPTE ST 2022-6, which established an SDI-over-IP baseline, then added AES67 for audio over IP, and followed with SMPTE ST 2110 for standardized transport of audio, video, and ANC. JT-NM TR-1001-1 enables the creation of network environments in which end users can take delivery of new equipment (compliant to the recommendation), connect it to their networks, and configure it for use with a minimum amount of human interaction. The JT-NM Tech Stack Part 1 summarizes relevant standards, specifications, and documents specific to additional constraints related to this domain of use.
JT-NM TR-1001-1 consists of four areas:
• The network environment defines use of Precision Time Protocol (PTP) for time synchronization of IP flows in the network, DHCP for IP address assignment, LLDP for devices to identify themselves to the media network switches, and DNS-SD for service discovery when using AMWA NMOS IS-04.
• Discovery and registration using AMWA NMOS IS-04 to discover compliant devices on a network and register them with a central registration server that will enable the control system(s) to know what devices are active and are compatible on the network.
• Connection management using AMWA NMOS IS-05 to control switching between IP flows on the network.
• System resource, specifying system-wide constants used by all devices on the network, such as PTP and IS-04.
As part of the presentation schedule, at IP Pavilion Theater, Ievgen Kostiukevych, from the European Broadcasting Union (EBU) and the editor and coordinator of the the JT-NM Tested Program will present a summary of the Test Plans and Results, the reasoning behind, the technical details, what was changed in the new revisions, and how it all was executed.
The Alliance for IP Media Solutions (AIMS) is a not-for-profit organization dedicated to the education, awareness, and promotion of industry standards for the transmission of video, audio, and ancillary information over an IP infrastructure, as well as products based on those standards. The group represents the interests of broadcast, pro audio and pro AV companies, and technology suppliers that share a commitment to facilitating the industry's transition from baseband to IP through industry standards and interoperable solutions that enable the rapid evolution to open, agile, and versatile production environments.
The 147th International AES Convention in New York will be co-located with the 2019 NAB Show New York, also taking place at the Javits Convention Center Oct. 16-17. The full schedule of presentations for the Audio/Video-over-IP Technology Pavilion is now available at: http://www.aes.org/events/147/aoip/?displayall.
