Today’s topics • Nautel and Telos Alliance Collaboration • Virtualization and the cloud • The HD Radio opportunity • Review HD Radio TM Drift Elimination Solution • Solution ingredients: • Telos Alliance Omnia Enterprise 9s • Software HD Radio Server • Made for Radio: E2X and MPX • Demo 1: FM+HD Time Locked in the cloud • Cloud Hosted Air-Chain: flexible, easy deployment • Architecture options and resiliency considerations • Demo 2: Cloud Hosted Air-Chain • Panel Discussion/Questions
So why this current collaboration and why now? • Nautel and Telos Alliance: Passion & innovation Digital Signal AoIP Processing • Change: • Industry & technology • Challenges: • Listeners, locations, competition, complexity • Fresh approaches • Apply new technologies, reduce complexity, drive out costs
Dig igit ital Radio matters more now • 65 Million HD Radio cars • Opportunities: • Podcasts/Streams On-Air • Ethnic broadcasting • Leased channels • Sports coverage • Over 2300 HD Radio stations • but 13,000 Analog only • Challenging for many: • Too complex? Too expensive? ROI? Cheaper, Easier, More Flexible Air-Chain Solutions
The Di Digital Di Differenc nce About 23% (almost one in four) of all cars on the road in America have an HD Radio receiver.
The Di Digital Di Differenc nce Consumers have gotten used to all their in-cabin entertainment sources offering images and metadata . . .
The Di Digital Di Differenc nce . . . except for analog radio.
The Di Digital Di Differenc nce This is your station in analog . . .
The Di Digital Di Differenc nce This is your station in digital . . .
The Di Digital Di Differenc nce . . . and this is your station in digital . . .
The Di Digital Di Differenc nce . . . and this is your station in digital . . .
The Di Digital Di Differenc nce . . . these are your digital presets . . .

The Di Digital Di Differenc nce The moral of this story? With all the media choices now available to the consumer, radio digital metadata & images can help level the playing field.
The Di Digital Di Differenc nce The moral of this story? The message is very simple . . .
The Di Digital Di Differenc nce Don’t be the “Blank Screen”!
The Di Digital Di Differenc nce HD RADIO DIGITAL BROADCASTING UPGRADE COSTS IN PERSPECTIVE In equivalent dollars, HD Radio technology now costs less to implement today than converting an FM station from mono to stereo did back in 1965. There was the expectation that higher quality audio would keep existing listeners for longer periods of time. That increased TSL came to pass. Stereo broadcasting quickly became the “table stakes” that all FM music broadcasters needed to remain fully competitive by the end of the century. Digital broadcasting has become the 21 st century equivalent of FM stereo.
Why virtualization?
Why clo loud? V Vir irtualization vs Physical Equipment • Alignment with the IT industry (IP Based) • The source of many of our standards (incl security) • The source of much of our hardware • Customizable and Flexible • Workflows vary widely and can change (hybrid options) • Spin up and down instances as needed • Example: Telos Alliance Omnia Enterprise 9s • More future friendly as standards and operating systems change • Reliability/Availability/Maintainability • Reduce traditional dedicated broadcast hardware • (ie one box per purpose) for greater redundancy • Less wiring / fewer site visits / remote management
Omnia Enterprise 9s • Built from the Omnia 9 • Highest quality audio • Common feature “DNA” • Undo • Advanced Signal analytics • Flexible Monitoring • Embedded pilot & RDS Omnia Enterprise 9s FM / HD Processor
