NOC server

The PMM Network Operations Center

The PMM NOC is a state-of-the-art facility operated by WGBH in Boston, staffed by expert personnel and equipped with high levels of redundancy to ensure no single point of failure. The NOC records most nationally distributed public television content, from PBS, APT, NETA, BBC, Acorn, EPS and other PTV distributors. We check this content for quality, prep it for broadcast, and deliver it to the PMM Cloud.

The NOC also monitors the health of the hardware and software at your station, as well as your on-air streams with 24/7/365 exception reporting.

PMM leverages highly efficient cloud technology

  • Managed by Sony's Ci Cloud service with a simple web interface accessible from any device
  • Hosted by Amazon Web Services (AWS™), world renowned for high security, high reliability, and high availability
  • No costly dedicated fiber deployment

Node server

A single rack of hardware housed at your station includes everything you need to play out your channels:

  • HD/SD servers
  • Branding
  • Storage
  • Automation

Working in conjunction with your Myers ProTrack system, the PMM Node automatically downloads ready-to-air national content from the cloud as you schedule it, eliminating costly and repetitive labor-intensive tasks at your station. Built-in disaster recovery provides storage for up to 30 days of content. So even if your IP network connection goes down, you're still on the air.

As a result (of PMM), Maryland Public Television is on target to save approximately $2 million over of the course of
our contract.


Chief Technology Officer Maryland Public Television

Welcome to your PMM Node

The first immediate and obvious benefit of PMM was the improved on-air look, which the new graphics capabilities provided. Not having to make a major investment in automation and archiving equipment also had a very positive impact on our budget. We are looking forward to using cloud storage for most of our local archive needs.
