HDTV - Why It's Better Than Standard Definition HDTV - Why It's Better Than Standard Definition
By Matthew Rizos
So, you're thinking about jumping on the HD bandwagon because you've been told "you just gotta have this, it's just so clear!". However, you're a bit of a skeptic and require concrete info on this HD stuff before you're going to buy that HD TV, the HD programming packages, cables and quite possibly a Blu-ray DVD player.
HDTV is better than standard definition TV and it's a very noticeable kinda better that we're talking about right here. The quality of HD all comes down to lines, tv lines that is. A standard tv (standard-def) signal from your standard satellite or cable programming is comprised of 480 lines of resolution. Once all 480 lines are layered on top of each other you get a picture that more or less looks pretty decent.
Now, let's take a look at a high definition signal which requires a Hi-Def TV (HDTV) and a hi-def signal (which you'll have to order from your cable or satellite provider). When you put those 2 together (the HDTV and the HD Signal) you'll get 1,080 lines of resolution, that's more than twice the resolution of standard definition! Now that's a BIG difference, not just some small upgrade to the clarity of the picture.
I should also mention that not only is HD beautiful to look at, it's also amazing to hear. HD programming and Blu-Ray DVD discs allow for very high quality audio streams since there is so much more room in the signal and on the Blu-Ray disc. How about a standard def TV signal or DVD? Not so much. Their audio streams often require more compression which cause audio clarity loss.
I have a blog that reviews HDTV's like the Sharp Aquos 32 LCD TV and Panasonic Flat Screen TV's.
