September Meeting – Single Frequency Networks for Radio

You should be able to drive around our terrain-challenged media market and receive excellent FM broadcast reception everywhere. Till now you haven’t been able to because of signal shadows and multipath. GEO Broadcast Solutions has been working on this throughout the nation and this year has been helping Entercom’s KWFN (FM) locally extend their 97.3 MHz signal through a series of boosters extending their coverage into northern San Diego County. The science of this is more complex than you might imagine; boosters have to be in-phase to the digital bit to work effectively. How do they do that?

Bert Goldman, advisor to GEO Broadcast Solutions, will give a talk at our next chapter meeting on the science and implementation of what they call “Maxxcasting™,” SFN’s for FM broadcast transmission. They’re also working on a related technology, “ZoneCasting™” that could allow geographic targeting of ads within Maxxcasting™ regions.

Join us Wednesday, September 18th at 12 noon at iHeartMedia, 9660 Granite Ridge Drive. We’ll provide a lunch and give Bert the floor for this important presentation.

Bonus March Chapter Meeting: SAS and Recent Digital Audio Protocols

While AES-67 Audio over IP and now AES-70 (GPIO and Control over IP) are popular in the radio broadcast world, a little known standard called IEEE-802.1 (also called AVB), is continuing to grow in the TV/Film, Production, Automotive and Consumer Industries. AVB (“Audio Video Bridging”) is an Audio over Ethernet (AoE) mechanism with auto QoS. With its growing popularity many other industries, the IEEE is positioning this technology to replace HDMI in entertainment systems, gaming consoles and TV Displays. AVB provides a mechanism for intuitive control and discovery. AES-67 is an Audio over IP (AoIP) topology, and while development is ongoing for “control and discovery”, (as is AES70), it’s poised to become the industry standard for radio broadcasting. We’ll outline key differences and typical applications for each protocol.
