From Analog to Digital – TV Technology Got Better

We should actually be thankful for the Plasma TV technology. Because of it, flat-screen TVs are now made available for almost every body. The government should also be sent a thank you note for issuing the guidelines in converting analog to digital technology. Finally, the world is ready for the mixture of technologies; everything will be easy for us users.

In 1964, initial dots of monochrome were able to be seen on monitors through plasma monitors. In 1999, the primary full color plasma monitor was developed and the images users see on their screens are now brighter and sharper. And as the years come, images become more and more vivid and lifelike.

Through the method of clipping images, a 4:3 ratio monitor was produced. The viewer cannot see the total frame and will only view widescreen video. In the traditional televisions, the picture ratio is 4:3 as well. But in movie screens, there is a 13:0 picture ratio and whole image is visible in the screen. So with the latest LCD models, they same system is used. A 13:9 ratio and entire image visibility is being offered.

All the same, a 4:3 ratio aspect can still be useful in the TV technology that we have today. Older televisions stretch images resulting to distortion of the image but now, newer technology uses a correcting algorithm to calculate the largest size of the picture and do scaling of image to fit it to the screen available.

Through Plasma technology, the images viewed on the screen are sharper and clearer and more colorful and lifelike. But even with the quality of the plasma TV and price you shelled out for it, if the signal is in the analog format on only capable for enhanced video showing, remarkable picture quality difference may not be observed.

Even with our new satellite TV services that broadcasts signals through high definition technology, if the original program is sent to a non-HD formatted unit, the signal that the user will receive on their houses will still be in analog format.

So in spite of the advances in technology and the introduction of Plasma technology, users still feel apprehensive about going with the flow since high definition formatting is not available in all countries.

Another drawback is that most Plasma TVs are manufactured in 42-inch sizes only. Smaller sizes that come in cheaper price tags are not readily available. Similarly, LCDs have produced larger screens and has somewhat outperformed Plasma over the years.
