The September Meeting

Our September gathering was a special treat, a tour of KCNC TV's facilities in Denver, where "digital" is the word! KCNC recently embarked upon a quest to convert as much of the plant to pure digital storage and delivery as possible. While it is still necessary to interface with the world of "NTSC" (and we all know what that acronym means), Channel 4 has taken that first big step toward a truly digital system throughout.

We assembled at the KCNC studios on Lincoln about 6:00 pm, and after a hearty welcome from Chief Engineer David Layne, we broke up into smaller groups, each accompanied by an engineering staff member to see the facility. We saw the new main studio with computer controlled cameras and lighting. We saw the graphics department full of high tech computer gear, all tied together through a sophisticated network. The commercials are recorded on hard drive, rather than on tape. Our tour guide told us that with the satellite hookup with CBS in New York, they know within a matter of seconds when a particular spot airs on each of their affiliates. Even the transmitter remote control in master control, or rather "Air Operations", draws a picture of the flashing tower lights on the screen! Many thanks to David and his staff for showing us around.

Following the tour, we headed for the conference room for refreshments and a talk by David Layne on the state of the TV industry. After a brief business meeting conducted by SBE chair Andre' Smith, David began his talk. David covered some interesting points during his address. For example, KCNC just made a significant investment in a brand-new analog transmitter. It is David's view that digital/high definition television will not be implemented and accepted by the viewing public before the new transmitter has been reasonably depreciated! The use of a smaller, lighter digitally equipped remote truck allows non-CDOT drivers to drive the vehicle to and from longer events coverage, saving on manpower costs.

David admits that just six months ago the digital future of KCNC, and perhaps the industry in general, was much clearer. Now, however, with different companies taking very different stances on how they will utilize the additional bandwidth, things have become much less so.

Our thanks to David, his staff and KCNC for hosting our meeting, providing the much welcomed refreshments and sharing their experiences to date with the move to digital!

Our next meeting will be on Wednesday, October 15 at the National Digital Television center. More details can be found in this letter. See you there!

AUDIO AND VIDEO ENGINEER CERTIFICATION

Earlier this year, the SBE announced the creation of new certification programs for Audio and Video Engineers. These are five year level programs (require five years experience) and require an exam. The exam is similar to the broadcast engineer exam but does not include any RF or FCC-related questions and concentrates only on audio or video engineering. The Audio and Video Engineering exams are given during the same bi-yearly periods as SBE's other certification exams.

If you are interested, call the SBE National Office at (317) 253-1640 and request information about either the Certified Engineer/Audio or Certified Engineer/Video programs.

Fiber Optic Talk

Chapter 18, Philadelphia

Boy! We saw a lot of different faces for Rik Berkbigler's talk on Fiber Optics, a subject which his company, ADC Telecommunications, knows quite a bit about. Rik discussed the history of fiber optics, going back into the 1800s. Was it 1859? And how it has blossomed since the 1970s to the significant growth of today.

In his chat, Rik brought out a few facts such as the difference between multi- mode and single mode fiber. Single-mode is about 1/9 the diameter of multi- mode and both are finer than a human hair. Single-mode cost about 10% more but is a better carrier. Since Fiber is so fragile, it must be protected by Cladding, and a cover that protect the cladding. When installing fiber great care must be exercised to prevent kinks or even small breaks, ant departure from smooth bends could affect the signal. Another fact noted by Rik is that the entire RF spectrum can be carried on just one fiber optic cable, with room to spare for more information.

The highlight of the evening was when Rik. who is a technologist, sat down and installed a connector on the end of a fiber. Total time about 15 minutes. Expect to spend about an hour your first time and don't be surprised if you blow it and have to redo it if you are not careful. Final inspection is looking through a magnifier at the end of the connector, looking for smoothness and lack of crack in the fiber.

(Ed note: Rick Cabalka, also of ADC presented a similar program to Chapter 48 last August.)

Insurance Available for Engineers Through SBE

PROinsure is your association's sponsored Professional Liability "Errors and Omissions" insurance program that provides profession-specific tailored coverage for its participating members. PROinsure was developed in response to a lack of profession-specific protection for professionals who are increasingly threatened by professional liability litigation. Professional Liability coverage is not provided by a Commercial General Liability policy, and Miscellaneous Professional Liability policies may not necessarily provide adequate coverage for a professional's services' risk exposures. Because PROinsure is a profession-specific developed program, association members' professional risks are properly priced and covered.

Unlike Miscellaneous Professional Liability policy forms, which provide generic coverage and may even exclude an insured's professional activities, PROinsure designs coverage that is tailored to a profession.

PROinsure is affordable because insureds are actuarially grouped within their own profession, instead of being grouped with other insureds from unrelated professions.

In the event of a claim, the insured may continue conducting business because coverage provides legal defense. If damages are awarded to the plaintiff, there is coverage available up to the stated policy limits.

Contact the SBE National office at (317) 253-1640 for complete information.
