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.

January 2014 Meeting Summary

 

Our January 30th, 2014 evening section meeting took place at the Mills-James Creative media video production lot, in Columbus, with twenty-five members and guests in attendance. It was a combined meeting along with the central Ohio SBE chapter 52. Mr. Victor Brewer, from the firm of Aerial Image Solutions, in Galena Ohio, made a very interesting and well received presentation discussing his company’s new and innovative approach to aero photography, utilizing a smaller than usual version of an air Drone called, the UAV. What sets it apart from other versions of aero imaging craft being used today, are the unique designs of its propeller motors, featuring smaller blades, as well as the power plant battery, and camera mount stabilizer. It has the capability of up to 25 minutes in the air, and is very safe for both the general public, as well as for the operator of the craft! After Mr. Brewer’s initial  presentation, the meeting was moved to Studio “B” of the facility, for an exciting live demonstration of the craft! The Drone’s versatility was pointed out as offering a device which can deliver a wide range of field environmental settings for any type of aero photography service needs including, an indoor studio/stage environment, or for an outdoor field use, as well.  The camera stabilizer mounts will support multiple types of camera designs including, video and still, HD, even futuristic technologies such as 4K! A very lively Q & A session, then followed.

October 2013 Meeting Summary

 

Our October 15th, 2013 meeting/seminar was held along with the  local SBE chapter 52, at the Lyon Video lot, in Columbus. Karl Kuhn, Senior Video Applications Engineer, Tektronix, Inc. delivered a comprehensive all day/early evening series of seminar presentations, covering all phases of video/audio chain testing and analysis. He started the morning session off with a nostalgic type 16 M.M. film produced in 1949 by RCA, which gave prospective broadcast video customers in those days, a preview of what was to become the new United States national broadcasting system. Next, he covered the basics of video/audio signal testing and how it has evolved from basic instruments such as the first generation of oscilloscopes, to digital display and analytical applications of today, and what will be needed tomorrow! He went over in detail, elements of testing such as video transmission chain review, time code, closed captioning, gamut and camera shading, to name just a few. He also outlined  some of the expected industry testing needs of the future such as for 4K/8K video, and file based video/audio archival storage systems. The generous refreshments for lunch and evening breaks, were furnished by Tektronix and Lyon Video, with approximately 40 members/guests in attendance.

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.

SMPTE Ohio Section

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.
