AIMS Adds JT-NM Tech Stack to Update IP Standards Roadmap

AIMS ip showcase ibc

The Alliance for IP Media Solutions (AIMS) released an update to the AIMS roadmap for a standards-based approach to applying IP systems in broadcast operations. The new roadmap includes the addition of JT-NM TR-1001-1, 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 comprises specifications and guidance designed to make SMPTE ST 2110-based systems easier to deploy and operate, helping broadcasters to work more efficiently.

The addition of the JT-NM Tech Stack Part 1 to the AIMS roadmap is the most recent in a series 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 followed by SMPTE ST 2110 for standardised 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 summarises relevant standards, specifications and documents specific to additional constraints related to this type 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 uses AMWA NMOS IS-04 to discover compliant devices on a network and register them with a central registration server that will enable the control systems to know what devices are active and are compatible on the network. Connection management uses AMWA NMOS IS-05 to control switching between IP flows on the network. System resource specifies system-wide constants used by all devices on the network, such as PTP and IS-04.

At IBC2019 Sept. 13-17, the JT-NM Tech Stack Part 1 will be a highlight of the IP Showcase in Room E106/E107 at the RAI Amsterdam. Attendees will be able to learn more about TR-1001-1 and talk to experts about the capabilities it enables. In addition, the JT-NM Tested program will give visitors a firsthand look at vendors that have implemented aspects of the new JT-NM TR 1001-1 specification.

“The JT-NM Tech Stack Part 1 is a critical link in the continuum of standards that are easing the broadcast industry’s transition to IP operations. Now that the industry is seeing broader and more mainstream IP deployments, JT-NM TR 1001-1 will play a key role in making IP installation and operation easier and more straightforward,” said Andy Warman, board member, AIMS. “At the IBC2019 IP Showcase, attendees can learn more about the AIMS roadmap, including JT-NM TR 1001-1.”   aimsalliance.org
