So, what is the difference between HDTV and regular TV? Let's tune in to find out. With television stations no longer broadcasting an analog signal, HDTVs are the staple for high-definition signals.
Think of regular TV as a single resolution. Analog TV sets show standard-definition programs. Regular TV, cable, and satellite channels aired this style of signal prior to the required digital conversion. Analog resolution is around 640 x 480 pixels. Analog screens contained 625 lines. That small of an amount doesn't produce a sharp picture. Furthermore, the aspect ratio of an analog set is 4:3, resembling a square. Picture shapes distort at that ratio.
Digital television describes standard-definition television viewed through an analog TV that uses a tuner to receive the digital signal. High-def programs won't show as detailed a picture compared to what shows up on a true HDTV.
What is the difference between HDTV and regular TV?
HDTV pictures show twice the detail than an analog set. Pixels of a picture are smaller and crowded together. The end result is a sharper picture. The picture quality explains why HDTV is a great choice for home theater systems.
HDTVs can have up to 1080 lines per screen. To qualify as a high-definition, the signal must contain a minimum of 720 horizontal lines of scanned pixels, 1080 lines of interlaced pixels or 1080 lines of progressively scanned pixels.
The screen ratio of a high-def TV resembles a rectangle and has a 16:9 aspect ratio. Luckily, digital signal can travel a longer distance without interference. The bottom line: a clear, sharp picture.
Clearly, HDTV is the only choice for newly manufactured TVs. Analog sets may be used, in conjunction with a converter, to receive the digital signal.
Before you start shopping for a flat screen TV, learn the truth about what's needed and what may be a needless expense.
Can I use a monitor as an HDTV? Yes, but you will need to make a few adjustments.
