June 2015 Meeting Summary
Our June 18th section meeting took place at the WBNS Digital Television Plant in Columbus, with 45 members and guests in attendance. Our guest presenter for the evening was Kenneth Hunold, Staff Engineer, Audio Production, from the Dolby Laboratories Inc. East coast offices, New York City. Ken started out his topics by going over the many Dolby Labs technologies and innovations developed over the past 50 years, which helped reshape the audio engineering landscape in various forms in key media industries such as, music recording, motion picture studio sound, cinema sound presentation formats, radio and television audio broadcasts, to name a few. He also showed the group various video/audio clips of key engineers/inventors within the Dolby organization who were explaining some of their products and designs over the years such as, an interview with their founder, the late Ray Dolby, and other creative staff engineers within their organization! He went on to present several video/audio clips detailing their new multi-channel surround audio format called, Dolby ATMOS, and in the field of video, a new wider pipeline, color gamut, and luminous channel technology format called, Dolby Vision. These two technologies are starting to appear in new dedicated cinema houses around the world, as well as the possibility of being included in the next generation broadcast standard in the USA referred to as, ATSC 3.0. Ken also discussed some of the new mobile devices now and in the future, which will employ Dolby ATMOS technologies in a more personable form. The meeting host, WBNS-DT is also significant for Dolby Labs because of the fact that Dolby Digital 5.1 audio broadcasting was pioneered by the station as part of their historic September 5th, 1998, remote HD telecast of an Ohio State University Buckeyes football, away game.
A lively Q & A session followed, Ken's well received presentation!

May 2015 Meeting Summary
The May 28th section meeting was combined with the local SBE Chapter 52, and took place at the WBNS Digital Television Plant in Columbus, with approximately 40 members/guests in attendance. The guest presenter for the evening was Timothy B. Anderson, CPBE Manager, Radio Market and Product Development, at GatesAir. His topic was the history of High Fidelity radio broadcasting, in the USA. Tim began his presentation at the starting point in 1932 with the application for the first experimental APEX AM Hi-Fi radio station license by CBS radio, in New York City. For the first time then the Experimental High Fidelity radio stations could transmit wider bandwidth signals from high points/towers which sounded more "life like, just like sitting in the concert hall" to specially equipped radios, some of which were even homemade, before regular commercial production took place. After an experimental period of around ten years, the FCC orders them to move over to the (then) new FM band, eventually becoming regular commercial Hi-Fi stations, and re-assigned to new frequencies, simulcasting alongside of their standard AM stations. He then traces some of the later Hi-Fi radio innovations to the TV industry such as, eventually using FM for the audio portion of the Television broadcasting channel. Tim then lists several of the AM/FM stereo radio broadcasting techniques developed and tested, which led to the standardized FM stereo multiplex system. He goes on to point out that with the eventual launching of a hybrid Digital radio broadcasting system or HD, it was then possible to transmit additional programming streams of data such as for still graphics, and other types of visual signals, and even several additional/separate audio program streams, all within the same frequency! One of his predictions for HD Hi-Fi radio broadcasting services included the possibility of some all digital AM stations, which will not be backwards compatible with those on the air today, in order to more fully utilize the AM band.
A lively Q&A session followed.

May 2014 Meeting Summary
Our May 15th, 2014 section meeting was combined with the SBE Chapter 52, and held at the Mills James Productions lot in Columbus. 25 members and guests were in attendance for two very well received topics such as, the 130 year history of the firm Osborn Engineering, and the top ten displays/topics featured at this year's NAB conference/show. The guest presenters for the evening were Don Archiable, a Technology designer from the Cleveland office of Osborn Engineering, and Assisting in the presentation was Tyler Slentz, also a technology designer with the firm. Don started out with a historical outline of the many stadiums the firm has designed over the decades such as, Yankee Stadium, Wrigley Field, and even The Ohio State University "horse shoe" stadium! He mentioned that today's modern stadium designs must include not only complete high end video/scoreboard type displays, but also the latest designs of both fixed and moveable video cameras, and audio pick ups, and a requirement for a comprehensive wireless infrastructure to be in place to handle all of the current, as well the expected future, wireless communications needs! Tyler then gave an overview of the top ten most innovated displays at the recent NAB such as, a 4K/8K UHD-HD image comparison demonstration. He also showed a graphic of the expected broadcast Video/AUDIO/IT facilities of the future, where conventional scattered/segregated TV/radio/newspapers/studio and news operations, will all be part of just one large "one roof" type IT platform, thus reducing redundancy of operations, as well as costs. A lively Q&A session, followed their presentation!

February 2014 Meeting Summary
Our February 26th, 2014 section meeting took place at the WBNS Digital Television Plant, in Columbus, where 40 members/guests attended an outstanding and informative presentation by Ken Hunold, from The Dolby Labs-east coast office, New York City. Ken opened his presentation outlining and discussing the history of Television broadcasting service in the United States, and specifically the various audio formats which have been used. He began with TV broadcasting's official launch at the 1939 New York World's Fair, and went through various audio enhancements introduced over the years, leading to what we are accustomed to today. He also included his predictions, for TV audio broadcasts of tomorrow. He pointed out that early TV audio broadcasting actually used an AM type RF signal in the chain, which had to be routed through a separate radio set, via a phono plug type patch cable, from the TV set. This was later changed to a FM type signal format, which was then included within the TV set cabinet itself. He traced some of the various types of TV audio broadcasting enhancements which were introduced over the decades such as, two channel matrix MTS, Dolby ProLogic Surround, which included a bass reflex channel. He added that a major improvement to TV audio performance occurred with the FCC mandated change over to the ATSC 1.0 digital TV broadcasting standard, which included the Dolby Digital 5.1 Surround audio format. That innovation resulted in viewers then having a multi channel audio experience at home, more closely replicating the typical one heard in a movie theatre. A few minutes of a Sept. 1998 Ohio State Football game telecast produced by WBNS-Digital HD Television was played back, which launched the first Dolby Digital 5.1 surround audio broadcast. He also played back a special presentation going through the history and basics of a movie theatre sound system, as well as a new process introduced last year called, Dolby Atmos, which can provide up to 64 independent speaker channels from a 128 track mixed movie master. Some of those speakers are even placed in the ceiling over the audience, thus creating a more "immersion experience." This allows an audience the ability to actually isolate specific "audio objects" around the auditorium! He predicted that TV audio formats of the future will also include more surround channels/speakers in the consumer's home theatre setting such as, 9.1, 11.1, in an effort to match the expected viewing enhancements created by future TV video standards such as, 4K, higher frame rates, greater color gamuts, curved TV screens, to name a few. A very lively Q & A session followed.

September 2013 Meeting Summary
Our September 26th, 2013 section meeting took place at the WBNS Digital Television plant in Columbus, with 30 members/guests in attendance. Tim Anderson, Harris Broadcast Manager-of strategic Radio market and product development, from Mason Ohio, delivered a comprehensive presentation on the topic: “Terrestrial HD Radio-Past, Present, and next generation!” Tim started out by going over the earliest days of digital signaling communications in the USA, starting with the basic wired telegraph, and moving on to wireless telegraphy, and voice signaling. From that period on he then spanned a 120 year period of significant achievements in radio transmitters and designs, leading to the present day’s HD radio technology. This now includes features such as “iTunes tagging” where after a song is heard on a HD radio station, a listener can “tag” it for future purchase. Another feature he went over was “Artist Experience” which enables a HD radio broadcaster to transmit the Album cover artwork that the song, which is currently playing, was taken from, as well as sponsor and other types of promotions, all displayed on the screen of the HD radio. He also mentioned that beginning with the 2014 automobile year, all vehicles sold in the USA, will have HD radios installed as standard equipment, with all of these latest features! Finally, he outlined plans for future, next generation HD Radio broadcasts, and what those will mean for the overall survival of the terrestrial Radio broadcasting industry. A lively question and answer session followed his very interesting, and well received presentation.

May 2013 Meeting Summary
The May 16th section meeting was held at the WOSU-AM/FM/TV Public Broadcasting stations lot, located on the campus of The Ohio State University in Columbus, with 25 members & guests in attendance. The guest presenter for the evening was Kevin Bauman, President of the broadcast tower consulting firm of Paul J. Ford and Company-Structural Engineers. Mr Bauman gave an updated presentation covering the current and past structural standards for broadcast steel Antenna Towers and supporting structures, which included an outline of the five most recent years when standards/practices have been modified. A year by year comparison was outlined reflecting the various upgrades to some of the established standards, which may have changed. In some cases, the standards have shifted due to more modern data accumulation, and the resulting data hardware/software analysis, etc. One of the main standards which changed were the two which related to a tower’s ability to withstand the effects of wind and ice, especially in areas of the United states where the effects are felt the most. A slide of a computer generated wind and Ice map was presented which shows those particular areas, and how they influenced the modification of the new standards. Mr. Bauman’s well received presentation was followed by a lively, Q & A session.
