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.
Al Salci of Sierra Automated Systems and Engineering Corp. visits us Wednesday, March 27 at 12 noon at iHeartMedia, 9660 Granite Ridge Drive, San Diego. He provides lunch, then will give the presentation. Members and guests are all welcome.
About our Guest Speaker
Al Salci is a veteran analog and digital designer, and software engineer with over 35 years experience in broadcast communications. Originally from Toronto Ontario, Al holds a Bachelor of Science degree from Toronto College of Electrical Engineering & Technology. Al started his career in Television Broadcast designing time code products for Telcom Research, Evertz Systems and Leitch Video. Al moved into radio in 1983 as Director of Engineering for McCurdy Radio Industries where he developed audio consoles, switchers, intercoms, and other audio products.
Later, Al joined RTS systems in Burbank as Senior Digital Design Engineer and developed 4-wire intercom systems to enhance their 2-wire TV camera communications networks. Al Salci teamed up with Ed Fritz, another veteran design engineer in Burbank and started Sierra Automated Systems & Engineering Corp. that specializes in high-density digital audio distribution and management systems, audio control console surfaces, large-scale AoIP systems, and fully integrated intercom systems. SAS is celebrating over 34 years.
Over-the-Top and IPTV continues to evolve with more infrastructure bandwidth and more bandwidth-efficient compression schemes. Learn about Dozer™ ARQ and other protocols now built in to some of the encoder/decoder pairs DVEO offers that give live media transmission a whole new level of dependability.
Local supplier DVEO representative Nicholas Joseph will present “OTT/IPTV: One of the Futures of Content Delivery” at the next SBE Chapter 36 meeting. Join us Wednesday, March 13, 2019 at 12 noon at iHeartMedia, 9660 Granite Ridge Drive, San Diego. We’ll have his presentation after a free lunch.

The IEEE Broadcast Technology Society will be hosting the ATSC 3 Roadshow at locations throughout the United States. BTS will be hosting the one-day course on the new ATSC 3 digital television (DTV) transmission system, taught by expert Gary Sgrignoli of Meintel, Sgrignoli, and Wallace, the noted digital TV transmission consulting firm.
This course will develop a fundamental understanding of the ATSC 3 digital transmission system’s Physical Layer, provide attendees with practical application ideas and update them regarding the progress of the spectrum repack and ATSC 3 deployment. Attending the IEEE Broadcast Technology Society’s ATSC 3 Roadshow will earn attendees SBE credit towards re-certification and can facilitate preparation for the upcoming SBE ATSC 3 Specialist Certification exam.
One of the gripes about early IBOC HD radio installations is that they required inefficient Class A amplification and often a second, dedicated transmitter and/or antenna, not to mention special studio-transmitter links (STLs) and frequent manual time alignments. Messy business.
The new Nautel representative Jeff Wilson, came to San Diego February 20, 2019 to introduce himself and make a presentation on “Making HD Radio Deployments Easier and More Affordable,” describing new systems that take a lot of the pain out of HD Radio deployments.
Many thanks for the talk and for lunch, Jeff!
