Well, another year is over. During that year I wrote 29 blogs. Did you miss any? Were there some you meant to act on, but other things got in the way? Or maybe you meant to send me an email and yell at me about something I wrote (I love those emails). Here's the list of all my blogs from 2014. Each one is a link. Just click on it to go to that blog. And, of course, you can always send a comment in the form at the bottom or send me an email directly (steve.lampen@belden.com). And if you have an idea for something else I should write about, I love those emails too!

If you google the name "Lampen", one thing you get is all the light bulb manufacturers in Scandinavia. Around the year 1400 or so, my family moved from Saxony (or somewhere like that) to England, and we were lamp makers. My British grandfather spent his entire life trying to convince himself that our last name was not German. My British dad quietly gave up the mis-translation. Now a lamp in 1400 was little changed from the pot of oil with a wick in it which goes back to the dawn of time, but you would think that would have led me to work in the lighting industry. I remember going to CEBIT, one of the largest electronic tradeshows in the world, in Germany. This show is so big, the buildings are permanent. And one of these buildings was all the lighting equipment and fixtures. On the front of the building was the huge word "LAMPEN". So, of course I had someone take a picture of me in front of my building.

Back in 1995, Belden brought out 1694A. It was an instant success. It was the first cable designed specifically for digital video. We won lots of awards at NAB and other shows for this cable. Of course, you can't use a cable without a connector, so in the months leading up to NAB we handed out rolls and rolls of the new cable to all our connector friends. Some people even doubted that anyone could make a BNC connector for this new cable. Back in the analog days, our mainstay was Belden 8281, the king of analog video. People loved it, even though it was a little stiff. As far as connectors went, the quarter-wavelength of analog video (4.2 MHz bandwidth for NTSC) was just under 18 metres (around 59 feet). Now a connector is way less than 59 feet, so it didn't matter what the impedance of that analog connector was. Any impedance was fine. It was then that a million broadcast engineers learned (or figured out) that the connectors they had been putting on the cable for almost 50 years were 50 ohm connectors - even though the cable was 75 ohms impedance.

I spend a lot of time in the fancy cable section of Belden. These are cables for high-frequency applications, such as digital video coax, or 10-gigabit data cables. These cables all use bare copper conductors. On the other hand, if you look at the Belden catalog from the 50,000 foot view, you will see a whole lot of cables we make use tinned copper. If you're an ancient engineer or installer (like me) you came from a time when tinned copper conductors were pretty much everything. Products like 8451 and 9451 and almost any analog audio cables are all tinned copper. Go back to the coax cables from long ago, and many of them are tinned copper. So what happened? And why is Lampen bringing up this issue now? Very simple. Belden has brought out a line of cables that are all tinned copper.

Last week I was in Hollywood at the SMPTE yearly shindig. I gave my ultimate paper (so far) on 4K Video over Coax. With 500 people in the room, it occurred to me as I began that I had the perfect group to find out some things. So I began by asking my audience a question. "If I could make a single coax that would run 4K video as far as you want, how many people would put that in?" I waited for a couple of seconds. Nothing happened. No hands went up. None! An article in the TV Technology website by Deborah McAdams the next day said there were hands that were 'tentatively' going up, but I couldn't see them.

First of all, I need to apologize. A few blogs ago, I wrote my usual piece about where I will be travelling. I suppose I should always add "the best laid plans of mice or men" because, as I also believe, "this too shall change". That is the motto I go by. So if something good is happening, you'd better enjoy it because "this too shall change". And if something bad is happening, just hunker down because "this too shall change". Since I am on a quotation kick here, "There is nothing constant except change...except from a vending machine."

I'm an old Belden guy. As I mentioned in an earlier blog, this is my 50th year as a Belden customer. And every one of those years I had a Belden catalog. In fact, one of the first things I did when I joined Belden as an employee in 1991 was start to collect old Belden catalogs. I now go back to 1964 in original, complete catalogs. I have bits and pieces of older catalogs, back to 1939....with rubber video cable!! In fact, if you have a Belden catalog before 1964, I would LOVE to have it. Tell me what you have and what you want for it.

Movie, Motion Picture, Flickers…which is it?

I really have a problem with the word MOVIE. It sounds so juvenile. Pictures that move! Sounds like something from 1900s, back when the frame rate was really low, like 16 frames a second. No wonder they called them "flickers". I still occasionally hear someone say, "I'm going to the flicks." Don't you? I guess some things just stay with us. So, instead, we call it "motion pictures" which doesn't sound a whole lot better. Last February at the HPA (Hollywood Post Alliance) the final speaker was an industry guru, John Watkinson (with his long hair and long beard, he LOOKS like a guru.) He got up and the first thing he said was a real epiphany. "I have never seen a movie or a motion picture." The audience couldn't figure out just what he was saying. "All I've ever seen is a series of still images, run rapidly in front of my eyes." And because of 'persistence of vision' which we humans share with only a few other creatures on earth, it looks like a moving picture.
