HDTV Technology

HDTV technology was first introduced in the US during the 1990s by a group of electronics companies called the Digital HDTV Grand Alliance. HDTV is also capable of “theater-quality” audio because it uses the Dolby Digital (AC-3) format to support. HDTV has at least twice the linear resolution of standard-definition television (SDTV), thus allowing much more detail to be shown compared with analog television or regular DVD.

HDTV can be recorded to D-VHS (Data-VHS), W-VHS (analog only), to a HDTV-capable digital video recorder (for example DirecTV’s high-definition Digital video recorder, Sky HD’s set-top box, or TiVo’s Series 3 recorder), or an HDTV-ready HTPC.

Digital signals, like the ones from DVD players, are converted to analog when played on traditional TVs. Digital signals are transmitted using computer code — ones and zeroes — which means they are less susceptible to interference and provide a higher quality picture and sound than analog. Digital TV broadcasts for local channels are also offered over-the-air (OTA) in many regions for those with digital TV antennas. Digital TV in Media Center allows you to watch and record high definition TV signals that might be available in your region.

You must have an HDTV-capable monitor which includes a built-in high definition tuner or an HDTV-ready television which requires an external tuner to watch HDTV. Televisions being sold are capable of displaying the digital signals produced by broadcasters like ABC.

LCDs generally have a higher native resolution than plasma TVs, but in the real world the difference isn’t that noticeable (more info on HDTV resolution). LCD spec sheets often talk about response time, but in our experience, almost all newer LCDs have adequate response time to deal with fast motion to the satisfaction of most viewers.

Plasma life span: The life span of plasma TVs is another area that’s improved dramatically over the last few generations of the technology. Plasmas look equally good from very wide angles. Plasma LCD General Screen sizes 42 inches to 65+ inches 5 inches to 65+ inches Cabinet depth 3+ inches 3+ inches Power consumption (more info) Slightly less efficient per square inch Slightly more efficient per square inch Price Usually less expensive for screen sizes over 42 inches Usually more expensive for screen sizes over 42-inches Features PC connectivity Less common but still included on many models More common than on plasma TVs Other features Varies per model Varies per model Picture quality Motion blur caused by display Negligible Difficult to discern on most models, although subject to more blurring than plasma.

Screen sizes are increasing and prices are dropping, so visit your local electronics store to pick an HDTV that fits your taste, space and budget. HDTV television technology is available in a variety of different set types, from super slim Plasmas and LCDs, to dependable “box” CRTs. HDTV is just one part of the DTV transition.

Reverse Cell Phone Info

Technological advances move so fast today that it is sometimes hard to keep up to date with them, and even if you wanted to it would be a full time job. This means that the majority of people only find out about new technologies that are actually of relevance to them. Whilst this can be useful it also means that some technology that you can use in your everyday life can pass you by.

One of these things is reverse cell phone info, you might have heard friends or family referring to reverse phone number searches, reverse cell number searches, reverse telephone number searches or something similar. Reverse lookup is a phrase that is used to describe the process of using an online service to gain information relating to the owner of a particular telephone number.

Using reverse telephone number info services can also help you to find out the residential address of that cell numbers owner. Such information can be used for a multitude of different purposes and reasons. Many people will tend to use this reverse cell phone info to get to the bottom of unknown telephone calls to their home or business or to check up on a partner or their children. It can also be used to quickly find the address of the person who a missing mobile phone belongs to so that it can be safely returned to that owner without any fuss. Info gathering is just as easy as using a search engine to perform an Internet search and it can be just as fast.

Latest Technology Invention

What are you talking about? – Archimedes and latest technology invention in the same breath? For those not in the know – Archimedes was the ancient Greek’s most famous mathematician. He was the one who ran through the streets naked yelling “Eureka” (I have found it) when he solved a very important problem while sitting in his bath.

The latest technology invention is this – taking what most probably the latest and using it in a new way. Archimedes had scribed some of his theories on goat parchment somewhere between 287-212 B.C. Amazingly, this parchment has lived on – and in the middle ages a Monk scraped the papyrus and OVERWROTE Archimedes’ writings – (which was probably the best thing to happen – because the writings lived on (covered over) as a Christian prayer book – thus not subject to destruction by anti-science thinkers of the Dark Ages and beyond).

Without getting into the whole story – the manuscript has lived on to this day – where it was purchased at auction for about 2 million dollars, and then very graciously turned over to classicists and old book restorers. It was found that the prayer book had been written over some other writing.

Here is where the latest technology invention comes in. The experts were having trouble reading the underlying script, naturally. A physicist that worked with the Stanford Synchotron Radiation Laboratory – which runs the Stanford Linear Accelerator Center – just happened to get some info on the Archimedes project while at a conference.

This physicist studies spinach! His latest technology invention was studying how determine iron and other elements in spinach. He – through the info he received – found that the ink used by Archimedes would have iron as a base.

The next step was to contact the classicists and restorers of the manuscript and suggest using his tools (the Stanford accelerator) to scan the book like he did his spinach – and the iron content in the ink should stand out (even through the overwriting).

After over four years of preparation – the use of this latest technology invention was accomplished. The scanning of the document is being done as we speak [beginning August 4, 2006]. The results are pretty amazing – and are available online and with a webcam.

This is one of the first instances where classicists and language scholars and physicists (nuclear and other) have worked together on a project such as this. The concept is mind-boggling – two such diverse fields working together to bring one of mankind’s greatest minds back to life with his writings – which have been buried beneath prayers for thousand of years. This is truly a fascinating use of the latest technology invention.
