Beginner's Guide to HDTV - HDTV Guide, Comparison & Reviews | YouReviewElectronics.com: "One of the biggest and fastest growing trends in electronics is High-Definition (HD) Television. Since the advent of color TV, there haven't been many revolutionary advances when it comes to televisions. TV's are one of the most popular and commonly used electronic devices in most households but we've been subjected to low quality TV signals for years now. Poor quality signals and old tube TV's are slowly dying and HDTV is the hot new trend. But if you've ever been shopping for a new TV or HD service you'll know there are many confusing high tech terms and features. Before you go shopping and possibly spend thousands of dollars on a new high-tech TV, learn some of the basics of HDTV so you know what you're shopping for.
HDTV stands for High-Definition Television and is received through a digital connection instead of the traditional analog signal. It's kind of like a DVD (digital) versus a VHS tape (analog). HDTV's provide a clearer picture, richer colors and smoother motion when there is action on the screen.
How does HDTV work?
The big difference between HDTV and a standard signal (SDTV) is resolution. HDTV's can display a much higher resolution than standard signals so you receive a much clearer picture. Some common resolutions that you'll find being produced by TV manufacturers are 1080p, 1080i, 720p and 720i. Don't worry, we'll explain the p's and I's later. HD also typically allows you to receive a widescreen picture.
What's the difference between HD ready/capable TV's and normal HDTV's?
Finding out the HD capabilities of a potential new TV is very important. Selecting the wrong option can end up costing you quite a bit in the long run. There are two basic options when buying a new TV: HD Ready/Capable or HDTV. HD Ready/Capable TV's have the potential to display an HD signal but further equipment is required to produce the signal. You'll need a separate HD tuner to receive HD quality stations. As HDTV is becoming more popular, many new televisions have a built in HD tuner. If you're looking for a TV to display an HD signal, finding one with a built in tuner is going to be your best option.
