Education – The key to DTV’s Success
By Larry Bloomfield, Author & Publisher
 
 
Having recently returned from a trip of just under 14,000 miles; extending from coast to coast, covering 31 venues, of which the top 19 television markets in the US were included, visiting television facilities, vendors and the like, it is unlikely that there are many people in this industry who have a better idea of the condition of the transition to digital television here in America.
 
At each of the 31 venues, I was able to share the technology that ten companies, who chose to underwrite my venture, had to offer the industry – A Taste of NAB. The Road Show, as it was also called, was structured as an educational opportunity; not a sales pitch. I made it a point not to know the prices of any of the equipment or services: that was up to the sales people the attendees would contact, if they were interested.
 
What prompted the Taste of NAB Road Show were the various responses to my question, early on in the year: “Will I see you at NAB this year?” As a writer for several trade magazines, host of a broadcast technology based website and publisher of an on-line newsletter, I like to put a face with the voice at the other end of the phone. The response to that question was shamefully negative, for the most part.
 
With most of the major networks estranged from NAB, most engineers wishing to attend do so out of their own pocket. That has not always been the case. The tariff for an engineer or technician, irrespective of their location here in the US, to attend even a day or two is equal to a week or two’s pay.
 
NAB (National Association of Broadcasters) and the International Broadcasters Convention (IBC) is an educational opportunity for both technical and non-technical television personnel alike. These two events are the only place an engineer can, in one location, see the preponderance of latest technology our industry has to offer and have the golden opportunity to speak with many of the engineers who developed it.
 
Then at those stations that do send some of their personnel to either of these events, it’s usually only the top brass that get to go; and then, many of them are sequestered away in corporate meetings when they should be out finding out what is going on in the world of television technology. It is just simply stupid for a television facility not to send their people to events like these. You can not make informed decisions if you are not informed.
 
There are societies, such as the Society of Broadcast Engineers (SBE) and the Society of Motion Picture and Television Engineers (SMPTE), who have as part of their regular meetings, programs and presentations from various manufacturers and service providers on the latest wiz-bang technologies that each have to offer. The sad part is that these meetings are not all that well attended. Many managers are reluctant to give their technical staff the time to attend: the really good managers will encourage their staff to attend and even see that their dues, fees and even meals, etc. are covered by the company, but these are few and far between.
 
So simply put, this is the current dilemma facing the engineers here in the US; they don’t, or are not permitted to avail themselves of educational opportunities. This is especially true in the larger markets. Don’t think for one minute that the engineers and technicians here in the US are not smart. Television engineers come in all shapes and sizes with varying degrees of knowledge. I had the fortune to meet the brighter caliber of engineer; the dumb ones don’t go to educational opportunities like our road show.
 
It was interesting to see the various facilities across the country. We had some really great hosts. I was particularly impressed with two television stations: WKYC-TV in Cleveland, Ohio and KEZI-TV in Eugene, Oregon. Each is very well laid out, opulent in many respects, while being very functional. WKYC certainly was the eye catcher. KEZI, a very small market TV station, was producing a syndicated television show for national distribution, while I was there. A very impressive feat in a medium market.
 
As for the transition to digital (DTV) from analog television, if you look at the numbers, it isn’t going all that well. There are approximately 1600 full power analog television stations currently on the air here in the US. Less than one quarter of the full power stations are classified as non-commercial. All commercial analog television stations are supposed to have had their parallel digital transmission equipment up and on the air as of May 1st of this year. As of August 4th, there are only 450 stations in 135 markets (there are 210 US markets) delivering digital signals and many of them are non-commercial. The non-commercial stations have until May of 2003 to be on the air, digitally.
 
The full power stations that don’t have their digital facilities up and working have requested extensions from the Federal Communications Commission (FCC). Some have even asked for a second extension. The FCC has not looked too kindly on these second extensions and has recently denied some fifty stations’ request for additional time, saying that they will impose fines if things don’t turn around, and soon.
 
What is really interesting is this number, 1600, does not include all the low power (LPTV) stations dotting the country side, much less the plethora of translators that extend the coverage of the full power transmitters into areas that would otherwise not be served. There are ten states, only one of which is east of the Mississippi River (sort of a half continent North/South dividing line), that have over 300 translators and of those, a couple have over 600. Many cable companies take their feeds from these translators; some from second and third translator hops. Most all of these, LPTV stations and Translators, have not addressed the transition to DTV.
 
There are a number of other issues compounding and impacting this seeming quagmire. I’ll only be able to address a couple of the more serious.
 
Let me start out by saying that the modulation issue, 8VSB (eight level Vestigial Sideband) vs. COFDM (Coded Orthogonal Frequency-Division Multiplexing), is virtually mute at this stage of things here in the US. 8VSB works, and works quite well. It takes less power to cover the same area as COFDM, but there is one problem; multipath. Multipath kills any chance of the signal being decoded in today’s receivers, despite Motorola and NxtWave Communications’ claims to “Solves Multipath Problems.”
 
There is one glimmer of hope that was on display at NAB 2002: CASPER, by Linx Electronics, Inc. of Palatine, Illinois. Instead of trying to cancel, or kill, all but one of the multiple signals in a multipath environment, CASPER uses all the signals, aligns them into one signal that the decoder can deal with.
 
In the early days of UHF, the FCC required set manufacturers to include a UHF tuner along with the more popular VHF tuner. Needless to say, that is one of the keys that gave UHF television a kick start and you can see where it’s at today. The same thing needs to be done with DTV. Until that happens, the DTV industry is at a loss.
 
Statistics indicate that some 85% of American homes are connected to a cable franchise. Cable companies are adamant when it comes to the subject of carrying both the analog and digital channels of local broadcasters during the transition phase of the DTV implementation. Don’t confuse this with cable companies who say they are delivering digital signals. That only means that they’ve digitized the local TV station’s analog signal. And don’t confuse high definition television (HDTV) with DTV. HDTV is only an enhancement that may come with DTV, as do data services etc.
 
Another issue that will be coming alive soon is the converter box market. There are a lot of legacy analog TV sets out there that will be useless once the transmission has been made and analog goes away. One Japanese company is offering their solution with a price tag in the US$450 (~£287) range. Another, WOW-TV in Salt Lake City, UT has targeted their box to this same market for under US$200 (~ £127), but it hasn’t hit the market yet.
 
Copyright is said to be one of the delaying issues in the transition to DTV. The greed and avarice of the money people in Hollywood, despite them seeming to have the world’s largest money magnet, is unequaled anywhere. Hollywood’s money people have whined and squealed over this issue since the beginning of DTV, saying that its quality is too close to what they have to offer and want HDTV’s quality diminished so people will be less likely to copy movies. The US Congress is even entertaining a massive copyright law that should be scuttled, if we’re fortunate.
 
There is no amount of education that can cure Hollywood’s problem, but there are opportunities, on a local level, similar to those I took with me across the US. Those engineers and other broadcast personnel who take advantage of these educational opportunities will have a reasonably safe future in this industry; those who don’t will one day be looking at the call letters on the outside of the building, wondering why they don’t have a job inside.
 
In conclusion, it appears that there are folks hard at work solving the problems with our DTV system. DTV is here, and here to stay. It’s only a matter of time now. Many of the answers to these questions will come from the kinds of folks I met during the Road Show.
 
Would I recommend anyone else doing a Road Show? Only if they like to see people walking away with gratitude in their hearts, on their minds and faces for the efforts you put into making it a professionally beneficial experience. I certainly have learned a lot from the Taste of NAB Road Show. Will I do it again next year? We’ll see.
