Busting Myths In High Definition

One of the great assets of satellite TV is its ability to educate at the same time it entertains, using its power as a visual medium to transmit information that would otherwise be left to the imagination. One successful show using this formula is Mythbusters, a show hosted by Hollywood special effects professionals that uses science to investigate commonly held perceptions about the natural and man-made world as well as various urban legends and urban myths that continue to persist in American and world culture. The show has been on television for about eight years now, giving the special effects team and their assistants plenty of opportunities to challenge conventional scientific and cultural wisdom. Their tests have ranged from the silly (can cockroaches actually survive nuclear blasts?) to tests which may actually have significant impacts on our day to day behavior (can you really blow up a gas station by making a call on your cell phone at the pump?). It turns out that it’s highly unlikely that cockroaches would survive a nuclear blast, as the Mythbusters team found out by irradiating several of the insects, although they still do seem equipped to outlive the human race in the case of a nuclear holocaust. And, it turns out that according to the Mythbusters, fears about blowing up gas stations using cell phones are highly overstated. There is some criticism over whether the Mythbusters’ methods are really scientific in nature. While it’s doubtful anyone is going to be writing a physics or materials engineering paper based on the results of a Mythbusters episode, the team does seem to take reasonable...

The High Definition Television

The expansion of hdtv is High-definition television. The hdtv means television signals broadcast with a higher resolution than standardused to refer to television standards developed in the 1930s to replace the early experimental systems, even though, not so long afterwards, Philo T. Farnsworth, John Logie Baird and Vladimir Zworkin had every developed competing TV systems but resolution was not the problem that separated their substantially distinct technologies. It was patent interference lawsuits and deployment problems given the tumultuous financial climate of the late 20’s and 30’s. Most patents were expiring by the end of WW2 leaving the marketplace wide open and no worldwide standard for television agreed upon. The world utilized analog PAL, NTSC, SECAM and other standards for over half a century. The terms HD ready and HD compatible are being utilized around the industrial world for marketing purposes. They indicate that a TV or display is able to accept video over an HDMI connection, utilizing a new connector design, the primary purpose of which appears to be to ensure that digital video is only passed over an interface which, by agreement, incorporates copyright protection. Even HD-ready sets do not necessarily have sufficient pixels to display video to the 1080-line (1920×1080) or 720-line (1280×720) HD standards in full resolution with out interpolation, and HD-compatible sets are usually just standard-definition sets with an HDMI input. This is really a confusing use of the terms HD and hdtv. MPEG-2 is most commonly used as the compression codec for digital hdtv broadcasts. The hdtv is capable of “theater quality” audio because it uses the Dolby Digital (AC-3) format to support “5.1”...

Entertain Better With Full High Definition Led Tv

As the newest form of high definition TVs, LED televisions produce the greatest picture quality available on the market today. Any home theater enthusiast can benefit from this amazing technology. But there has been a lot of confusion surrounding the concept of “LED TV”. Even many marketing professionals and salespeople who should know better are falsely explaining what an LED TV is to their prospective customers. To set the record straight, it is important to note that the Light Emitting Diode (LED) designation refers to the backlight system used in the Liquid Crystal Display (LCD) TVs, not the chips that produce the image content. LCD chips and pixels do not produce their own light. In order for an LCD TV to produce a visible image the LCD’s pixels have to be “backlit”. So LED TVs are still LCD TVs. It is just that these new sets use LED backlights rather than the fluorescent-type backlights used in most other LCD TVs. In other words, LED TVs should actually be labeled LCD/LED TVs.
