Are you familiar with HDTV basics? Are HDTV and DTV the same thing? What do I need to know before purchasing a new TV?

Are you thinking about buying a new TV right now, or at some time in the near future.

Is your Television Ready for the Transition from Analog to DTV on February 17th, 2009?

THIS DATE is much closer than you realize.

A better understanding of the transition to Digital TV, and knowing these HDTV basics, will help you to be ready when it’s time to consider a new television.

Buying a new television today can be overwhelming and involves more than just visiting your local television or electronics store. Shopping for a Digital TV or an HDTV can be confusing with all the abbreviations, terms, resolution, dpi, formats and the options that you can get on televisions today. And you thought that purchasing a new car was bad.

So What Do Consumer’s Need to Know

There are so many decisions confronting today’s unprepared consumer, just trying to navigate through this complex maze can be a daunting experience. However, many of these frustrations can be avoided by doing some homework before hand.

Things To Know Before You Go

What is Digital TV … and is Not. What is the Digital TV Transition… and how it will affects you. How is HDTV different from all other television formats … and How. Understand what you want and need, so you’re not Sold something YOU don’t want or need!

So Where Do You Start? Familiarize yourself with the different Terms and Classifications

TV Classifications:

NTSC Analog TV- (National Television Systems Committee), Traditional TV; now being phased out on February 17th.

ATSC Digital TV – (Advanced Television Systems Committee), DTV;

This is “SDTV” – Standard Definition TV – the new, (digital) TV Standard;

replaces NTSC Analog TV.

Integrated HDTV – or simply, HDTV; DTV with an Internal (built-in) High Definition TV Receiver.

This is able to Receive and Display all ATSC TV Signals – Including HDTV Signals.

Digital-HDTV – ‘Capable’ or ‘Ready’- Digital TV that is able to DISPLAY HDTV – BUT ONLY with the addition of an EXTERNAL HDTV Receiver.

EDTV – Enhanced Digital TV – a classification* describing Digital TV’s that are basically ‘high-end’ SDTV’s. While these often include some type of technical features, added by the Manufacturer to enhance the picture, nevertheless, the picture quality does NOT equal HDTV. Technically, there is virtually no visual difference between an SDTV and an EDTV – with the possible exception of the higher price.

* For many Consumers, this classification is of questionable value; by paying more for a TV tagged “EDTV” the consumer is only getting what can best be described as an ‘upgraded’ SDTV. The question is, how ‘up-graded’ is it, if the TV simply meets the standard for SDTV?

Different TV Display Technologies:

CRT – (Cathode Ray Tube):Traditional TV Technology – The established standard for television displays; best overall value – picture quality and cost; major drawback is bulk and mass as size increases. Plasma Display – Ultra-thin design, High Contrast Ratings, ‘Fixed Pixel’ Display: Size up to 60+ inches; some display limitations – costly, high burn-in risk; picture quality affected by inability to display black-color; displays are extremely heavy and fragile; picture quality lost as pixels fade; many Plasma Displays do not display HDTV resolutions. Development continues.

LCD – Liquid Crystal Display: Thin design, size limitations; good computer monitor; sharp picture for static displays; problems displaying images in motion; many LCD Displays are not HDTV capable. Development continues.

LCoS (Liquid Crystal on Silicon) – Improved LCD Technology, may hold promise for future HDTV display; costly; manufacturing problems continue; development ongoing.

DLP (Digital Light Processor) – Uses Chip and Software Technology – exciting, alternative display technology; excellent HDTV display; eliminates most short comings of other technologies; moderate cost; some viewers question “softer” picture, and use of “color-wheel;” promising future – development continues.

TV Display Configuration:

Aspect Ratio

The width to height ratio of a TV Monitor or Program.

Aspect Ratio can apply to either the television monitor (hardware), or to the TV program format.

Traditional – (4:3) aspect ratio; the display has ‘square’ appearance. All Analog TV programs are in 4:3 aspect ratio.

New ‘Wide Screen’ (16:9) aspect ratio; the display is rectangular.

Digital TV (SDTV) programs can be in either 4:3 or 16:9 aspect ratio.

HDTV is always in 16:9 aspect ratio.

As you can see, consumers have a number of decisions to make, long before making their final buying decision. Understanding the basics of HDTV requires us to become familiar with an array of strange-new ‘tech-speak’ terms.

Examples:

Aspect Ratio – width to height (4:3) or (16:9); refers to the TV Display and to TV Programs.

Picture Resolution – 720-p; 1080-i; 480-i/p; – and recently added, 1080-p.

Progressive Scan – display method (“p” in 720-p)

Interlaced Scan – display method (“i” in 1080-i)

D/A – A/D – digital to analog and analog to digital converter

STB – Set-top Box (aka: Receiver, Tuner, Decoder or Descrambler)

OTA – ‘over-the-air’ or ‘off-the-air’ – refers to Local TV Broadcasts

These are just a few of the new terms you will encounter.

The Digital TV Enigma

As consumers begin their quest for information about the Digital and HDTV, they soon notice what seems to be an “Information-Void.” Trying to get Useful, and Reliable information about what is needed to buy a digital television set can seem difficult.

Try asking questions regarding basic HDTV; for example: Does the Transition from Analog TV to Digital TV mean that everyone is forced to buy an HDTV? or, What is the difference between SDTV and HDTV; or What is needed to have High Definition TV reception in your home? Now compare the different answers you get or the lack of knowledge on the sales persons part.

Note: The seller must disclose or have posted information regarding the lack of digital capabilities of any television for sale to you the consumer. This is a government mandate.

In stark contrast, at the opposite extreme, is the continuous flow of ‘misinformation’ and ‘disinformation.’ This flood of unreliable information has inundated the general public. The path to useful and reliable information is littered with inaccuracies, fallacies and myths. And this is further aggravated by misleading advertising and marketing ploys.

As an example, here’s a question asked repeatedly by perplexed consumers concerning the transition from Analog TV to Digital TV:

“Can you tell me if it’s true, that “normal” TV is going to be stopped and everyone will be forced to buy an HDTV? I don’t believe they can do this … But if it’s true, when will it happen?”

Okay, that’s really two questions…

The answer to the first, is of course – NO, it’s not true. At least not in the way the question is posed. While it is true that “normal TV” (meaning traditional NTSC-Analog TV) will end, replaced by ATSC-Digital TV, you will NOT have to buy an HDTV!

IMPORTANT NOTE: The FCC’s mandatory transition from Analog TV to Digital TV does NOT refer to, nor mean ‘High Definition Television!’

Note: If you choose to keep your analog television you can purchase a converter box that will make viewing your television possible. There are coupons to help with this purchase on the website listed below and it is free to print.

This highlights one of the primary sources of so much of the public’s confusion concerning Digital TV and HDTV. These are two discrete terms, yet they are frequently used incorrectly – as if they were interchangeable words with the same meaning. They are NOT the same; they designate two distinctly different classifications of television.|

High Definition Television is ‘digital’; however, HDTV is just one (1) of eighteen(18) ‘Digital TV Formats’ designated in the ATSC Standard.

It is important for consumers to understand that ‘Digital TV’ does NOT mean HDTV.

Digital television’s “Standard Definition TV” – SDTV – is NOT equal to HDTV – High Definition Television.

So, it’s up to each consumer to inform her/him-self on the basics of Digital-HDTV.

But – Be careful!

Don’t take anything for granted; don’t accept statements at face value.

Verify everything you hear or read about Digital-HDTV, comparing it with different sources.

The Digital Difference

Digital TV signals are made up of coded instructions – (the same ‘bits’ of ‘ones and zeros’ that make your computer work, and give life to ‘CD’s’ and ‘DVD’s') – which are transmitted to your Digital Receiver, (aka: Tuner, Decoder or Set-Top-Box “STB”) which in turn deciphers the code.

A Digital TV receiver isn’t concerned with signal strength, or what conditions exist between your set and the transmitter. As long as the signal gets to the receiver, and the code can be read, the Digital TV is able to reproduce a near-perfect picture – virtually identical to the original, back in the TV Studio.

A distinct advantage of digital broadcasting is that bad reception is a thing of the past. One reason Cable TV caught on is because it delivers clear TV pictures without regard to the viewer’s location. Viewers don’t have to be constantly adjusting the antenna in an attempt to “tune-in” a weak signal from a distant transmitter to get a clear picture. Digital TV (DTV) eliminates the “snow” and “ghosting” caused by the weak signals from distant or blocked transmitting towers. If the analog television set does not receive a strong, undistorted signal from the tower, you will not get a perfectly clear picture.

Both digital and analog television signals weaken, the farther they travel away from the transmitting tower. On an analog TV, the picture slowly deteriorates from bad to worse as the distance between tower and receiver increases. However, the picture on a digital set will stay perfect until the signal becomes too weak for the receiver to distinguish between a (1) and a (0), at which point the image disappears completely.

This has been referred to as “the cliff effect” – the picture remains stable until it abruptly “drops off” the screen. This might be compared to sending Morse Code. As long as the person at the other end can make out the dots and dashes being transmitted they will be able to read the message. Once they lose the distinction between a dot and a dash they lose the message. Digital TV acts the same way; instead of sending dots and dashes, it sends millions of (1′s) and (0′s) every second.

As long as the TV Receiver can read the (1′s and 0′s) it displays a virtually perfect picture. The bottom line … you either receive a 100% quality image, or nothing at all. What this means to the digital television viewer, is not having to worry about getting a “bad” picture. Either you have a picture or you don’t. However, if you are receiving over-the-air, “OTA” (Over the Air) broadcasts, it is crucial for the antenna to be accurately directed towards the signal source – the transmitting tower of the station you are watching.

Adding an “H” to ‘DTV’ = W O W! While our objective is to become familiar with HDTV basics, so far we have focused mainly on Digital TV – DTV. What then is HDTV – High Definition Television? And what is the difference between DTV and HDTV?

DTV differs from NTSC-analog TV in the technology used to transmit the signal. And we looked at some of the reasons why Digital is better than analog. But when comparing Digital TV or “SDTV” (Standard Definition TV) to HDTV, the difference is as night and day! High Definition Television is digital television – BUT … It’s IMPORTANT to understand that Digital TV does NOT mean HDTV! HDTV is just ONE of (18) ATSC designated formats that comprise Digital TV. In High Definition Television, the picture displayed on your television screen begins as an HDTV signal captured by HDTV Cameras, (or converted from film or another format with HDTV Equipment). The HDTV Signal is transmitted to the HDTV Receiver and finally displayed on an HDTV-Capable TV Monitor. But it must also meet the ATSC Standards for High Definition Television in order for it to be “true” HDTV.

Note: It is more than likely you will confront mis-information stating that Digital TV in various configurations is ‘high definition television.’ This is NOT True! You may also be told that as long as the TV meets one or two criteria, or if it has been enhanced by the Manufacturer, using some proprietary engineering “magic,” this makes it – “as good as” – HDTV. Again, NOT TRUE!

If what you want is HDTV, be sure the television you are considering, is really “True” High Definition Television. How Do you Know a TV is – HDTV? To answer this question a ‘bit’ of basic TV technology will be helpful.

It will be helpful in understanding some of the basic elements of HDTV by educating yourself. After all, this is a discussion about Digital-HDTV – possibly the most significant ‘leap forward’ in consumer-technology to impact our society in more than a century!

The image you see on your television screen is comprised of a series of horizontal lines. An electron gun ‘shoots’ energy beams (light) which strike a layer of phosphor on the inside surface of the picture tube, causing it to glow. These glowing lines create the image displayed on your TV screen. How they are formatted, which resolution is used, what standards are met, are some of the factors that determine the type of television picture you will receive.

TV Resolution.The quality of the picture displayed on the TV screen is primarily the result of the television’s “resolution.” Put simply, TV ‘resolution’ refers to how many horizontal lines are displayed on the TV screen.

Note – Although the horizontal lines are counted, (in this instance) this is referred to as the “Vertical resolution,” because the lines are counted from top to bottom – or vertically. TV Resolution is sometimes expressed as the total ‘pixel’ count, which is a product of the number of lines and number of pixels per line

Why Is “Wide-Screen” TV The DTV Standard?

DTV sets are sold in two ‘Aspect Ratios.’ Aspect Ratio refers to the ratio between the horizontal (width) measurement and the vertical (height) measurement of the screen. This ratio is also used in reference to how the picture is transmitted and displayed on the screen. The two aspect ratios used in DTV are (4:3) and (16:9). That is, (4) units wide by (3) units high, and (16) units wide by (9) units high respectively. Your NTSC-analog television has an aspect ratio of (4:3); the screen appears almost ‘square’ because it has just slightly more width than height. For instance, a (4′) wide screen would have a height of (3′).

This brief introduction to Digital TV and HDTV basics, provides an overview (intentionally simplified) of how DTV differs from traditional Analog TV, and how HDTV differs from Digital-SDTV; and a little about the Transition from Analog TV to Digital TV. This is just a start towards a better understanding of Digital TV. Now that you’re familiar with some of the basics, you are better prepared to begin considering which Digital HDTV is right for you.

So you are interested in the world of politics but do not know where to find a good daily politics blog. In this article I will provide you with the best method for finding the blogs you want to read. I will not tell you what to read, I will tell you how to find a political blog you want to read -one that suits your specific tastes.

If you know essentially nothing about the world of political blogging you should understand a few things right off the bat.

Firstly, a daily politics blog can come in one of two forms. The first type is the kind most people probably think a political blog looks like. It is the “personal blog”. It is made by one individual. The second type is the corporate type. It is like a company as it has several writers or “contributors” who make up the daily blog into what is very similar to an online newspaper.

Secondly, the thing you need to know right away upon entering the politics blog universe is that the vast majority of political blogs are biased or at least “lean” one way or another -they are opinionated news. There are however many politics blogs that take a non-partisan or neutral approach to their blogging. Remember, this kind of blog might be articulating a point of view just like partisan blogs.

Finally, the most important thing to do, in my opinion, is to do research on the political blogs you start reading. If the blog is a personal one try to understand where they are coming from. If the blog is a corporate one look them up on Wikipedia. See who owns them and possibly which way they “lean” (left or right for instance).

Alright, so now that you are schooled in spotting blog types and their content you can start searching for a great daily politics blog.

I suggest you immediately figure out what kinds of political blogs you want to follow before you start following them. You should have an idea of what you are trying to accomplish by reading a blog online. Are you trying to educate yourself? Are you looking for other people who will articulate your shared positions on politics? Or maybe you want to act like a media analyst by looking at daily politics blogs on both sides of the political spectrum!

Whatever you are looking for and wherever you might be on the political spectrum, there is really only one final step to finding a great blog you can follow every day and it involves Google.

Search Google for the words “politics blog” (or blogs) or “political blogs” (or blogs) while combining a word that specifies exactly what kind of material you want to see. For example, if you are a life long Republican in the United States you might want to put “conservative” or “Republican” in front of politics blog. If you are a centrist you might want to type “moderate” or “centrist” at the beginning. What you put in addition to the first words is up to you and will depend on your political views.

Using Google is the best way for newbies to get settled in to the political blogging world as the first page results are usually the more established personal and corporate blogs. Since so many mainly personal political blogs die in their first year (people just stop writing), using Google is the ideal first step. Keep in mind you can use other search engines but Google superior in my humble opinion.

Happy reading!

For many fly-fisherman, fly-tying is a serious hobby. Not only is fly-tying economical, it is enjoyable. Nothing beats the thrill of mastering a new fly pattern, or creating specialized flies for ones’ unique fishing situations. Also, one cannot underestimate the sense of adventure that accompanies the fly-fisher on the prowl for the perfect materials, whether browsing the local fly shop, ransacking a craft store, or even salvaging road kill.

Given that tying your own flies provides so much satisfaction, why buy flies online?

Obtain local fly patterns

The first reason is that as your fly fishing experience grows, your desire to test new and foreign waters increases. As a result, your need for localized patterns becomes more important. Sure, you want to do the research and tie your own variations of the Club Sandwich before you hit the Snake River for the first time, but there’s something to be said about fishing the tried and true local patterns on your initial outings to foreign waters. With that idea established, you can either buy these flies from a local shop or purchase them online. I recommend doing both.

Say you live in New Jersey and you’re planning your first trip to Colorado. You and your buddies plan to hit a few a rivers within 10 days. Before you go, do research on the internet – find out what’s hatching on these rivers when you plan to visit them, and what patterns work best. Then, based on your research, purchase enough flies online to cover you while fishing these waters. Now you have a safety net – you won’t have to worry about not having enough flies for the rivers you’ll fish at the end of your trip.

Next, research local shops on the internet – find out who the proprietors are and when they are open for business. Now this idea might seem obvious to many of you, but make it a point to stop at these shops before you fish. When you arrive, ask them about recent fishing activity and what flies they would recommend. Tell them about your trip, let them know you found their site on the internet, and ask for their advice. Tell them what flies you already have and ask about what else you may need. If your budget allows, purchase as many of the flies they recommend.

Save time while supplementing your current collection

There comes a time in which your energy is better focused on fishing than tying flies. A typical North American fly-fisher and fly-tyer spends the “off” months tying flies for the season ahead. Many fisherman focus the bulk of their tying efforts on the winter months to prepare for spring, summer, and fall fishing. If you are one of those anglers who feel like they never have enough flies, purchasing your “basic” flies online can leave you time to focus on the more specialized, region-specific flies that you might not find on the web. For example, why not buy your attractor flies such as Adams or Stimulators, so that you can concentrate on the special mayfly flies that you know will require special attention to detail? The same idea applies to those “hard-to-tie” flies – if you dislike tying size 24 Tricos, why not buy those items online so you have more time to crank out the flies you prefer to tie?

Also, consider how much your time is worth. Think about your fly-tying time as if you were a professional fly-tyer. How much is an hour of your fly-tying time worth? If it takes you two hours to tie twelve size 26 BWO emergers, you might be better off spending $10 on a dozen of the same fly so that you can use those two hours to tie 18 Rusty Spinners.

Variety

No matter what you want to purchase, nothing beats the internet for window shopping. I have seen the same fly pattern tied three different ways on three different sites. This variety allows you to find the best pattern that matches your intended fishing location. For example, if you plan to fish faster moving water, your parachute patterns might need a bit more hackle, or even a brighter post. On the other hand, if you plan to fish tailwaters, your mayfly patterns might need to sit lower on the water. By the same token, if you intend to fish mostly in the spring, your mayfly patterns might need to be a lighter color than if you intend to fish in the fall.

By browsing different sites for the same patterns, you will be able to compare patterns and ascertain the right fly for you. The best way to do this is to open two or three browser windows at a time on your computer. Then go to different sites in each browser and compare the patterns you are interested in.

Save money

Quite simply, buying flies online can save you money. Not only can you find discounts for large orders, the actual cost of individual flies can be lower than if you purchased flies from some of the larger fly fishing retailers. The best online merchants often charge as little as 65 cents (sometimes, even 50 cents for fly patterns). One disadvantage is that you don’t get to inspect the flies before you purchase them, unlike in a store. I recommend buying a few different patterns your first time so that you can determine not only the quality of the flies, but the consistency of the quality across different patterns. For example, a good initial purchase might include a stonefly nymph, a caddis pattern, a mayfly emerger, a mayfly dun, and an attractor pattern. This way you could check the various elements of typical flies such as tails, dubbing, hackle, deer-hair, and hook strength.

Types of web sites

There are hundreds of web sites that sell flies online. These sites fall into two categories: companies that only sell flies, and fly shop owners who run web sites for their businesses.

Businesses whose sole purpose is to sell flies online usually have a greater amount of flies available. One advantage these sites offer is that they are more likely to offer discounts on larger purchases. Also, their web sites tend to be more user-friendly (though not always). Many of these sites typically include advanced functionality that make selecting and purchasing flies easier on the user. The best of these sites allow you to set up personal accounts or use “shopping carts” to store your selections before purchasing. In this manner, the purchase experience is more convenient. Shopping carts tend to be “persistent” – in that a visitor may select items to the cart one day and return to the site at later time to find that the shopping cart still contains the previous selections. This allows you to select items you are interested in, leave the site and do more research, then alter or add to your selections later.

Fly shop web sites, on the other hand, typically present the user with flies specifically relevant to the area that the fly shop services. You have a better chance of purchasing flies that are most effective to the area you want to fish if you purchase them from local fly shops. Furthermore, you are supporting the local economy of the area in which you desire to fish. Many fly shop web sites also include online hatch charts which can inform you of flies you most likely need.

The authors experience

In the spring, and summer I do a lot of fishing on the Delaware River in the Catskills Mountains of New York. Throughout the winter I will tie a decent amount of the flies I actually need. As spring approaches, I have found that supplementing my collection with web-bought flies ensures that I am ready to meet the various hatches encountered in the spring. Any Delaware River fly fisherman will tell you that hatch-matching is a critical part of success on this river. In my limited experience, I have encountered days in which four or five different hatches took place. On top of that, the hatches change from week to week. I have ensured a decent modicum of success by checking local hatch charts ahead of time and then purchasing a dozen flies from week to week.

Hopefully, these tips will help you increase the amount of flies you own, and enhance your fly-fishing experience.
