High Definition Television (HDTV) Gives you Superior Quality and is Increasingly Affordable

Today's high definition televisions (HDTVs) have become more affordable. Combine that with their superior performance, and there is almost no reason for any consumer not to upgrade their present television.

HDTV is really a digital technology that displays a digital image and creates digital sound. While the first broadcasts of HDTV signals were analog, now video compression allows entirely digital broadcasting of high quality video and sound. Which means both the picture and sound quality are exceptionally enhanced over the older analog standard definition TVs.

While the older standard definition picture tubes only showed 480 scan lines of data, the normal description for HDTV is 1080 interlaced (or 720 progressive scanned) lines of video information including 1920 pixels of information in each line. Displaying virtually square pixels. this provides an aspect ratio of 16:9

Such technology has in addition transfered to digital recordings. The time-honored DVDs are produced with the standard definition pictures with 480 lines of video content. The newer Blu-ray disks were designed with the high definition displays in mind and provide 1080 lines of video data.

More information displayed in the high definition screens means that the pictures are more crisp and exhibit more detail clearly. These screens can also be bigger without obviously showing the scan lines. And, the HDTV screens are wider than standard definition displays so movies will be shown in wider format that shows practically all of what you see at the movie theater.

Older television programs that were produced with a 4:3 aspect ratio can be viewed on the HDTV display with black bars on either side of the image. This is because the broadcaster is sending a HDTV signal with a 16:9 aspect ratio with the older 4:3 picture centered within the wider HDTV display.

A drawback of HDTV for viewing older 4:3 aspect ratio programs is that for a similar screen diagonal value (for example, a 32 inch diagonal screen), the HDTV display is literally shorter vertically when compared to a standard definition (4:3) screen. The reason is that the display is longer. A 32 inch 4:3 display is 19.2 inches tall while a 32 inch HDTV display is only about 15.7 inches high. This means that for a HDTV having the same diagonal dimension as an older 4:3 aspect TV, the overall size displaying an older TV program will then be smaller.

For watching an older TV program, in order to get the identical height and area from an HDTV as from an older standard definition screen you require a longer diagonal screen size. You must purchase a 40 inch HDTV to offer just a smidgen more vertical dimension than an older 32 inch standard definition screen. So, if watching older TV programs is important for your requirements, remember this requirement.

So, now you recognize several of the advantages of the newer HDTV standard for TV displays. At this point, it's time to decide on the size of the screen that's right for you and whether to get a Plasma screen or an LCD screen.

After you have decided to purchase a new HDTV, you'll want to choose what size is optimal in your viewing environment. After that you'll need to make the right decision about a Plasma screen TV or an LDC screen TV. Both are outstanding choices in the appropriate situation.
