All TV channels, full power will turn off analog signals, February 17, 2009. This is by order of the Federal Communications Commission. Consequently, many people rush to buy high definition televisions, especially during this Christmas season.
Unfortunately for consumers there are many options of TV out there. There are LCD, DLP, plasma, flat screens, projection screens, large ensemble, small ensemble – and all in high definition. With so many choices, and that number increases every day, even the most educated in high-definition technology may find their heads swimming.
Local TV expert and owner of the obligations of television and electronics, Bob Bond, offers some information to keep us afloat.
“The old format is four units to three units horizontal vertical. The new technology is 16 units with nine units,” said Bond.
This means that if you want the same size as the old 32-inch, you need to buy an HDTV 40 inches. Good general rule: The size of a diagonal HD series should be 25 percent larger than your analog TV.
But the proportions are not the only thing to consider. How do you send the screen image is another. You must choose between 1080i, interlaced scanning, and 720p or 1080p progressive scan.
“1080p is the highest quality units. E ‘unlikely that it will be released soon. The only thing that is like your 1080p Blu Ray or HD DVD,” said Bond.
Even the wiring is different. You can choose the analog cables, but will not give you true digital quality. A single cable called HDMI Digital will transfer directly from a DVD player or cable at all. Although HDMI is digital audio and video transfer, it is always advisable not to buy the cheapest on the market.
Tip: Do not feel pressured to buy. Just to get the manufacturer name and model number and check the manufacturer’s website. There are probably also a glossary with definitions of all terms of HDTV.
Do not bother to get a picture if you choose not to buy an HDTV. If you have cable TV, your cable company will convert local television stations for customers digital from analog and digital. Simply do not have the digital quality. If you receive programming from the old to the ears of rabbit, the government has a coupon program that enables you to get a converter for about $ 40
