HDTV


By: Alan Rhinehart

Have you ever watched a movie on a regular TV set, and then watched the same movie on an HDTV? If so, you would have noticed a huge difference! On the HDTV viewing, you see and notice things you've never seen before, even if you've seen the same movie several times! The colors are brighter, backgrounds are clearer, and details are better defined. HDTV is like looking out an open window, whereas in comparison, standard TV is almost like looking through a glass soda bottle. Because of CRT (cathode ray tube) technology, TV is often referred to as "the tube". After watching HDTV, watching standard TV is almost like trying to view through one!

HDTV, or High Definition Television, offers precision sound, original film quality picture resolution, and a wider, better detailed panoramic view. This is made possible by the use of true digital signal which is transmitted via satellite or cable directly to your unit. You'll notice that not only does HDTV offer extraordinary picture clarity and sound, but the scope of the picture just like watching a movie on the "big screen", inside a real movie theater!

The use of digital signal is what separates HDTV from your common television set. The reason why there is such a notable difference between the two is that conventional televisions operate on analog signal. Digital signals are much faster, meaning images are is refreshed more rapidly, therefore providing superb picture resolution. Analog signals are much slower. As a result, the images produced by a television using this type of signal are of low resolution. Simply put, the picture is just not as sharp and view is restricted.

Not only do HDTV's offer superb picture quality, but HD sound is second to none. This is because Dolby Digital surround sound comes standard with HDTV. So, not only does watching an HDTV remind you of a movie theater, it also has the sound system to further enhance the experience.

Along with better quality picture and sound, HDTV's are quite easily integrated with your computer. They are able to easily communicate directly with one another through the use of a type of data compression software such as MPEG-2. Once this software is successfully installed, a whole new world of multimedia technology is literally at your fingertips! For instance, CD-R applications can be transmitted to an HDTV, as well as HDTV programs can be downloaded onto your computer. Either way, the picture resolution is top notch and the signal is stable.
Lastly, HDTV's are more affordable than one might assume. There are many different ways to buy or finance an HDTV system. Some companies offer money-saving offers both in-store and online. Some of these include rebate programs; others include special deals, extra gifts or incentive packages offering items such as hundreds of dollars in gift cards. There are both in-store and online promotions as well as savings with shipping and delivery. Bottom line, HDTV is affordable for almost any budget and well worth every penny!

Digital World in Photography


Where are you going today? Are you going alone or together with your friends or family? Don’t forget to bring your camera. Don’t leave home without your camera. A lot of unique thing happen in the street. You can capture anything with your camera.
What is your camera? Do you still have your grandfather’s camera? Many people still use SLR (single lens reflection) cameras. SLR camera is great because you can create photography art. A professional photographer will use both digital and analog camera.

If you go to the city and enter the camera shops, there are not many conventional cameras available now. Most people are preferred to use a compact digital camera. A digital camera is slim, full with features and easy to use. You don’t have to bring a big size camera and film wherever you want to take some pictures.

When you need to buy a digital camera you must think about the price, brand, features, picture quality, mega pixel, services and guarantee, etc. You can choose many brands such as Kodak, Canon, Pentax, Panasonic, Leica, Casio, Nikon, Samsung, Sony, and other brand. A digital camera starts from 4 mega pixels and above 10 mega pixels. You can get a good quality picture from 6.1 or more mega pixel resolutions. Don’t buy a digital camera below the 5 mega pixels because the picture quality is not so good when you print your photo, especially when you want to print in a larger size.

Before you make a decision please consider the feature of the camera. Don’t forget to check the brochure and browse the information in the Internet. Make sure that the lenses size, zoom, and flash light, battery life, etc. fits your needs. Ask the shop owner about bonus if you choose a particular brand. Sometime they give some bonuses such as external memory or soft case. Most digital camera also include video capture capability, but make sure that you can make a video or movie with sound or audio. Video without audio is not complete. It’s a great idea if you purchase a digital camera in a promotion season. Digital cameras are now available for both professional photographers and amateur enthusiasts. A professional digital camera (DSLR) is expensive and the size it’s bigger than the compact size digital camera.

Digital cameras aim at amateur photographers’ market. They function as much as point-and-shoot cameras do, with automatic focus, face detection, smart capture, anti shake, automatic exposure, and built-in electronic flash. Pictures from these cameras contain fewer pixels than those from a more expensive camera and are therefore not as sharp. After taking pictures, the user can connect the camera directly to a television set or video cassette recorder, so the whole family can look at snapshots together. We are lucky because we live in a digital world, because image files can be transferred to a home computer, stored on disks, or sent to friends via electronic mail.
