AMWA IS-07 NMOS Event & Tally Specification

AMWA IS-07 NMOS Event & Tally Specification

What does it do?

• Provides an IP-friendly mechanism to carry time-sensitive information
  • For example: camera tally information, audio levels, control panel button presses and status

Why does it matter?

• ST 2110 does not provide an equivalent to GPI functionality
  • This leads to the danger of multiple proprietary approaches
• Consistency with other NMOS specifications

How does it work?

• Media Nodes emit and consume state and state change info
• Lightweight messages sent using WebSockets or MQTT
• Message flows connected using IS-05
