High definition television sets are a familiar sight in countless living rooms up and down the country these days. Yet whilst more and more consumers are enjoying the fantastic viewing experience afforded by HD TV, many of us still don’t know exactly what it’s all about and what the jargon actually means. It helps to know the technical terms, simply so that you can take better advantage of the deals and offers available on HD TV packages from manufacturers such as Sky.

First off, you need to know that there are different high-definition formats available on the market. More recent HD flat screens offer a resolution of 1366 x 768 pixels, typically using display formats of 720p and 1080i. Larger signals can be downscaled to fit, of course, but to display 1080i and 1080p signals in full, you would need to have a screen with a resolution of 1820 x 1080 pixels – or Full HD, as it’s understandably known.

What do these bewildering numbers all actually mean though? These numbers (720p, 1080i or 1080p) are formats in which sources of content are presented, before they are transmitted through the output device which for most people will be the LCD or plasma screen. In the simplest of terms, the higher the format, the larger screen resolution required to display it in its entirely – bearing in mind that a lower resolution screen will still be able to display it, albeit a downscaled version.

The resolution of a television screen is ultimately the number of pixels it can display, and this depends on the display unit and the video signal being received. Resolution has a horizontal and a vertical figure of course, given that video images are always rectangular in shape.

720p and 1080i were the original standards for HD television, and the first high definition devices supported these formats. The old-fashioned television set with its CRT display used a stream of electrons which is sent across the face of a tube coated in phosphors which then glow to finally give you the picture. This explains the diagonal lines you might sometimes have seen on an old television screen if it is not properly tuned.

However new technology brought progressive scanning, with which frames connect more easily, giving better quality and improved picture detail – similar, in fact, to how films are shown at the cinema.

High definition television is the point at which we’ve arrived in the development of this technology. Most high definition television is broadcast in either 720p or 1080i, so if you have a screen which can’t display 1080p then it probably won’t be a problem unless you’re an avid game player keen with a console that requires graphics displayed this way.

But for all that, the difference between these formats remains all but insignificant. So you have to make the decision what kind of screen you want depending on your needs, bearing in mind that with any format you will get incredible picture quality and ambience.

Avatar HD for the Android platform is developed by Gameloft, well known around the Android universe as having the best set of games.

Avatar’s game does not follow the movie’s plot in every detail but you can see the same (though not complete) world of James Cameron’s Avatar and embark on a journey of redemption and discovery two decades prior to the events in the film.

Play as Captain Ryan Lorenz into the body of an experimental human-Na’vi hybrid, becoming the first avatar. I played this in easy mode and there were a few wherein I did not have an easy time. Although the combos for the avatar are repetitive, you get to upgrade your weaponry and armor as you accomplish mission by mission.

The game features around 15 levels, from the human-built mines and military strongholds to beautiful waterfalls and lush jungles that come alive at night with bioluminescent plants.

The controls can be a bit sketchy at times. The avatar character tends to move and evade backwards when it is moving so sometimes I got miffed when instead of jabbing forward to lunge at the enemy, my character tumbles backward.

Still, I enjoyed every press of my thumbs with this game. Absolutely one of the best games for Android. And it is not just the same arcade style shooting that you can do in this game. There are also game plays where you battle enemy ships in the skies of Pandora riding on a banshee in shoot ’em-up sequences.

Unlike big corporations, small and medium size business owners cannot afford expensive video conferencing equipment and systems from major brands like Polycom, Tandberg and Radvision. That is why the FaceVsion FV Express Combo, by FaceVsion Technology USA exists to solely provide any business the high definition video conferencing needs that they require at the most affordable prices.

As a business owner, I can tell you that I definitely would prefer high definition over low quality video conferencing anytime. This is because communication can sometimes be inaccurate if the video displayed cannot be clearly understood because of low quality.

The best thing about this FV Express Combo HD Video Conferencing solution is that it works pretty well with web applications that provide video conferencing services like GMail. With Gmail and FV Express Combo, you can make HD video calls over the internet. Your Gmail contact list can be automatically synchronized to your HD video conferencing contact list.
