How High Is Your Definition?
The increasing demand for high-quality television and new technology has given rise to High-Definition Television or HDTV. The shift from Analog to an all-digital system heralds a new dawn in the 65-year history of television. Hours of HDTV content are already available every night and this is sure to grow as Analog is phased out.
Basics of HDTV
HDTV is a new type of television that combines an HDTV tuner and HD-capable display. Nearly all of HDTV available in the market uses the 16:9 widescreen aspect ratio. An HDTV tuner can receive analog and digital over-the-air broadcasts.
A “HDTV-ready” television features only the high-resolution display and can only receive digital broadcasts if connected with a separate HDTV tuner. HDTV-ready TVs can have the 16:9 widescreen ratio or the square like 4:3 aspect ratio.
However, the arrival of new technology also calls for viewers to adapt to the situation. Those still using TV sets purchased nearly a decade ago will not be able to get the HDTV experience. For this you need to have a tuner to receive and decode HDTV signals from a source, and a high-quality screen that can reproduce the outstanding details and colors from a HDTV broadcast.
The chief reason why HDTV pictures look considerably clearer and crisper than normal TV is due to the higher resolution of HD. Normal TV pictures only have 480 lines of vertical resolution, while the most common HDTV’s have 1,080-line interlaces scan and 720-line progressive scan. The best analog quality that can be offered by an analog TV is also the lowest quality signal in digital TV.
Getting started in HDTV is not as expensive like in the past few years, as prices of tuners and HDTV’s continue to drop and the quality of the products are constantly improving. This is also in line with further technological improvements.
To help you maximize your HDTV setups without breaking the bank here are some tips to avoid costly mistakes and help you enjoy HDTV at its best.
