March 2014 Meeting: Local QVidium

Many thanks to KGTV for hosting the lunch Meeting on Wednesday, March 19, and to Steve Moreen of RF Specialties for picking up the lunch tab.

Our guest presenter, Dr. Ron Fellman, Founder and President of QVidium Technologies based here in San Diego, gave a highly informative lecture well targeted for the broadcast engineering audience.

Ron has had a significant involvement in the research and development of video transport over the Internet as both a Professor of Electrical and Computer Engineering at UCSD and the founder and former President of Path1 Networks.  His presentation provided a historical overview of video over Internet streaming technology as well as the state-of-the-art techniques now used in QVidium and QVAVC™ products to enable the transport of broadcast-quality video, including High Definition (HD) video, over Internet networks with reliability and minimal latency.

California Electronics Closes in El Cajon

Another surplus electronics store has closed its doors in the San Diego area. Long-running California Electronics and Industrial Supply on Johnson Road in El Cajon shutdown in February and will open only for customers who plan to buy large quantities of their existing stock.

In the past few years, retail electronics stores have dropped hobbyist stock or closed altogether as the variety and complexity of manufactured electronics goods available has increased and cost decreased. People seldom assemble or repair electronic hardware from scratch.

California Electronics was at one time a favorite stop for hams and tinkerers looking for cheap but hard-to-find electronics parts.

February 19 Meeting: Orban Update

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
