High Definition Television

High definition television are becoming more and more popular, many people are getting a HDTV because they believe that this is turning out to be the next standard in television sets, there is no wonder to this belief since the transmission quality is definitely superior to anything that came before it. The most common thing you can hear is that someone that just got a HDTV set says that he would not have believed how fast he would get used to this phenomenal quality.

In fact, most of the HDTV users say they don’t understand how they watched television “the old way”, and that they can not stand to watch a regular television because of its poor quality, this is even worst for sport addicts who confess that HDTV is almost a necessity for those football games.

It is not surprising then that this is not only an American trend, this HDTV madness is on a global scale, and like any other market rules this suggests that high definition will indeed become a very accessible purchase in a few year, the demand is predicted to grow in the next few years and as more television stations start transmitting in high definition more users are expected to join the market.

HDTV – HDTV Explained

You have probably heard of HDTV but you may be confused by all of the new terminology.
The maximum resolution on a standard analog TV is 720 X 480 pixels, which is about 337,000 total pixels. HDTV is part of the Digital TV specifications which has many different video resolutions. The two main resolutions to be concerned about are 720p and 1080i. The "p" means progressive and "i" mean interlaced, in both resolutions every second has 60 frames of video.

Progressive resolution puts 60 full frames on the screen every second. Interlaced resolution puts 30 frames of only odd lines and then 30 frames of only even lines up every second. Some people find that the interlaced video causes flickering.

The 720p video resolution is 1280 X 720 pixels, which gives 921,600 total pixels and the 1080i video resolution is 1920 X 1080, which gives a huge 2,073,000 pixels.

What is an LCD TV?

In an LCD TV or "transmissive" display, a light source shines through a panel of liquid crystals in order to display an image. A white diffusion panel behind the LCD redirects and scatters the light evenly to provide a more uniform image than most competing technologies.

The LCD face consists of two transparent layers which polarize a liquid crystal layer sandwiched in between. The front layer of glass is etched with a grid pattern on the inside surface to form a template for the liquid crystals. Liquid crystals are rod shaped molecules that bend light in response to an electric current; the crystals align so that no light can pass through. Each crystal acts like a camera's shutter, either blocking light or allowing it to pass through. A pattern of transparent or dark crystals forms the image. This same technology has been around for awhile, even in such unsophisticated items as digital watches.

LCD TVs use an "active matrix" LCD; the most advanced type of LCD. The active matrix design is based on TFT, or thin film transistors. These are tiny switching transistors and capacitors that are arranged in a matrix on a glass substrate, they switch the LCD pixels on and off. In a color TV's LCD, each color pixel is created by three sub-pixels with red, green, and blue color filters.

What is HDTV?

Some satellite TV providers, such as Dish Network, offer HDTV receivers with their packages. But many people don’t know what it means to have HDTV. Here is some insight.

High Definition TeleVision is what HDTV literally means. But high definition compared to what? In order to answer this question, we need to know a bit about the original analog TV system.

Analog TV
30 images per second (in Europe 25) are shown by normal analog TV sets. It does this by writing image lines horizontally, 525 lines in one image (In Europe 625) on the screen. The number of pixels on one line is about 500. This would be a definition of 500 pixels per line by 525 (or 625) lines. Compared to modern computer monitors this is really bad. Even the lowest resolutions monitors have higher resolutions (640 x 480) than an analog TV.

What is movie and movie history

Movie is a term that encompasses individual motion pictures, the field of movie as an art form, and the motion picture industry. Movies are produced by recording images from the world with cameras, or by creating images using animation techniques or special effects.

Movies are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them. Movie is considered to be an important art form, a source of popular entertainment, and a powerful method for educating — or indoctrinating — citizens. The visual elements of cinema give motion pictures a universal power of communication; some movies have become popular worldwide attractions by using dubbing or subtitles that translate the dialogue.

Do you have this in Full Screen

Do you still have one of those old TV’s? Well it may be time to upgrade to a new wide screen television. DVD’s are starting to be made in wide screen only. This is a good thing, because it’s going to enhance the movie experience in home theater systems.

So what is the TV do you need to have the best move experience, without breaking the budget? Believe it your not but picture quality is the thing that you want to be looking for, not the size or how much it costs. After all, if you can’t make out what’s on the TV then what’s the point? This brings me to the two types of formats, HD-DVDs and Blu-Ray DVDs.

Watch FREE HDTV with an Outdoor Antenna

With an outdoor antenna you can watch HDTV for free of cost. All you need is a high definition television or an HDTV-ready television. If you have a HDTV-ready TV then you might need high-def tuners such as Humax HRA100. These are high def tuners that will enable you to watch HDTV for free. This tuner can receive broadcasts that are high-def.

You need an antenna that can be installed outdoor which is connected to your HDTV or the high-def tuner. If you are close to the tower that broadcasts high-def signals then you can use indoor antennas also. The HDTV signals are considered as line-of-sight signals and hence you get a better reception of the HDTV signals if your antenna is in line with the tower that broadcasts the HDTV signal. For this purpose it is better to install your antenna in the roof of your house.

3D Animation

3D animation deals with electronically produced computer-generated 3D imagery used in motion graphics and digital special effects. In this case, the animator creates a design style or concept that tries to visually interpret and convey the required information using both new and traditional animation techniques.

The 3D animator will have to be well-acquainted with 3D animation applications and software, film and video production techniques, production processes, digital special effects, art and design movements and methodology, typography, styles of performance and dramatization, film and broadcast genres, technical scripting, health and safety regulations for the film and broadcast industry, and an understanding of budgeting and scheduling processes.

The job of the 3D animator is to design and realize original concepts, character and content creation. The animator, therefore, is responsible for devising and communicating creative ideas and accurate technical information. They have to provide the client with detailed estimates of costs, and work within the budget and schedule.
