Manny Acta - Class Act


The wife lucked into some tickets for the 2009 Natsfest in DC. I'm not much of a sports fan. Never really have been. I'm a geek. To me, jocks were those guys we made fun of when they weren't stomping mudholes in us just for kicks. Anyway, the Natsfest is an openhouse at the Nationals Stadium. Pretty much everything is open. We toured the various executive clubs, had our pictures taken with different players, and enjoyed the sights. One of the things that my wife wanted to see was the PNC club. At the time we went, Manny Acta, general manager of the Nats, was giving a talk. I'd seen him a few times during the afternoon. He'd signed autographs until he literally begged to stop because his wrist hurt. After that, he simply asked if he could just have his picture taken with the visitors.

Then the talk started. Manny was having a conversation with Charlie Slowes, the voice of the Nationals Radio. Then the floor was opened for questions. Four or five people managed to get in questions. The interesting part, to me, was how Manny handled the questions. He treated each one as if it was the most interesting thing he'd ever heard. He was straightforward, witty, and intelligent. At 3:30, he was told that only one more question would be allowed. Manny was surprised; his response was, "Do I have to be somewhere else?" That wasn't it. Another group was going to use the area after us. So we had to clear out. But it was obvious to me that he was enjoying the Q & A. Yes, it could have been an act, but Gywneth Paltrow at her best could not have matched him. He was terrific.

So, I have to give credit where it's due. Manny Acta is a class act.

DTV is coming!

In less than a month and a half, standard analog broadcasts across the US will cease. However, not all analog signals will cease. For example, if you are on cable systems, you will most likely still see analog for quite a while. If you are getting your signals over the air (meaning you use an antenna, not through a cable service provider or satellite dish), there are a couple of things to keep in mind:



  • Channel Numbers: In the analog world, the channel number referred to the actual RF channel (a 6 MHz wide chunk of spectrum) that your TV used. For example, if you were watching channel 2, that meant that your TV was tuned to a signal residing between 54 - 60 MHz. Or perhaps you were watching channel 13, which referred to the spectrum between 210 - 216 MHz. Well, in the digital world, it's not that simple. As part of the digital bit stream coming into your digital-ready TV (or digital converter box), each channel is assigned a "virtual channel number". This may (or may not) be the same as the RF channel. Look at the image at left. This shows the RF channel number (27) and the assigned virtual channel number (26-1). Most likely, the virtual channel number applies to the station's analog channel number, which most people are used to.

  • Multicasting: Notice how your digital channels are listed as "26.1" or "26-1"? That's because of something called "multicasting". That means that a TV station can put multiple programs onto one RF channel. For example, in the image shown, the channel is listed as "26-1". That's because it is the first program on the channel. But there are others. In this case, there were four programs running on this one RF channel. The first, listed as "26-1", was a program about home improvement. The second, third, and fourth programs (listed as "26-2", "26-3", and "26-4", of course), were a local program about Washington, DC, a cartoon, and a news program.

  • RF Channels: The FCC first established 82 channels for analog television (channels 2- 83). In the 1980s, the top 14 channels (70 - 83) were given up for a new service called "cellular telephone". Now, with the transition to digital television, even more RF channels will be given up; channels 52 - 69, to be precise. Starting on 17 February, only RF channels 2 - 51 will be available for television. Those channels from 52 - 69 (a total of 108 MHz) will be used for new wireless services. But, in a practical sense, this also means that, if you already have a digital TV or converter box, you will need to re-scan on or near that date. That's because many stations will be changing frequencies. Your TV will need to know where to find them, requiring a rescan of the RF channels.
