AIMS updates IP Standards roadmap

Includes the addition of JT-NM TR-1001-1, also known as the JT-NM Tech Stack Part 1

The Alliance for IP Media Solutions (AIMS) has announced what it describes as significant update to its roadmap for a standards-based approach to applying IP technologies in broadcast operations.

The latest roadmap includes the addition of JT-NM TR-1001-1, also known as the JT-NM Tech Stack Part 1. The new standard has been developed by the Joint Task Force on Networked Media (JT-NM) to automate installation and eliminate complexity, and it provides specifications and guidance designed to make SMPTE ST 2110-based systems easier to deploy and operate.

AIMS said 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 domain of use.

The new standard consists of four areas:

• The network environment defines use of Precision Time Protocol (PTP) for time synchronisation 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.

“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,” said Andy Warman, board member, AIMS. “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,”

“We’d like to encourage IBC2019 attendees to stop by the IP Showcase, where they can learn a lot more about the AIMS roadmap, including JT-NM TR 1001-1.”
