At our June meeting, Bart Schade, President and CTO of Path 1, discussed the technology behind the new Internet video streaming standard MPEG DASH, and how it contrasts to traditional real-time broadcast video transport. This was another presentation that could make you rethink your concept of codecs, since what you are sending with DASH technology are actual files–not just a stream of framed packets.
PiXiE is a contribution codec supporting SD/HD SDI and using MPEG-4 AVC video compression, HE-AAC/AAC-LC audio compression and pass-through audio. For those wanting advance information, see Bart’s recently released white paper “Real-Time Broadcast Video Services over the Internet using MPEG-DASH.”
At our regular May meeting, Chapter 36 welcomed new chairman Andrew Lombard of KGTV to the helm and thanked Doug Alman for two great years of service. Ellis Terry updated us on what’s going on at Nautel with a look inside Nautel’s new GV Series.
Many thanks to John Rigg and Clear Channel Communications for hosting the meeting.
Every year I look forward to the NAB Show. It’s this great change from the daily grind where I get to see old friends and new technologies, often in the booths at the very back of the exhibit halls. And the parties. Did you see Kool and the Gang at the CNN party a few years ago? Wow.
My first was in 1983, when the big exhibitors were RCA and Ampex, both showing off their amazing new 1″ tape machines, their commercial playing robotics systems, and Plumbicon low definition cameras with $30 – $100K price tags.
This year will be #30, after having missed a couple of years in the middle.
The SBE has some great stuff planned for this year. If you have time for nothing else, please make time for the 50th Anniversary Open House Tuesday. And did I mention certification points for attendance?

Radio broadcast engineers have been battling a certain inelegance in system design since the advent of hybrid analog/digital FM broadcasting. When you combine the complexities of stereo pilot, stereo L-R, and SCA subcarriers with the complexities of the Ibiquity digital sidebands, you’ve got some serious filter design issues and a lot of hardware.
On February 19th, 2014, Orban Founder and VP of Engineering Bob Orban gave a presentation via Skype reviewing his “A Full Bandwidth Standard” Radio World article discussing a new compositing standard designed to simplify the hybrid FM broadcast and decrease filter aliasing. Additionally, he commented on efficient codecs for audio streaming.
Many thanks to Orban’s rep David Rusch and RF Specialties rep Steve Moreen for lunch, a terrific presentation, and to John Rigg of Clear Channel for hosting the meeting and giving us a full tour of his plant. The place is really buttoned down. Continue reading February 19 Meeting: Orban Update→
