Today's high definition televisions (HDTVs) are getting more affordable. Combine that with their outstanding performance, and there is virtually no reason for a consumer not to replace their present television. HDTV is a digital technology that displays a digital picture and creates digital sound. While early broadcasts of HDTV signals had been analog, now video compression allows entirely digital broadcasting of high quality video and sound. This means that both the picture and sound quality are incomparably enhanced over the older analog standard definition TVs. While the older standard definition picture tubes barely displayed 480 scan lines of data, the accepted description for HDTV is 1080 interlaced (or 720 progressive scanned) lines of video information including 1920 pixels of information in every line. Displaying nearly square pixels. this provides an aspect ratio of 16:9 Such technology has also made its way to DVDs. The traditional DVDs were created with the standard definition pictures with 480 lines of video content. The newer Blu-ray disks are created having the high definition displays in mind and provide 1080 lines of video data. More video data contained in the high definition screens ensures that the pictures are sharper 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 screens so movies will be shown in wider format that displays practically all of what you see at the movie theater. Older TV programs that ended up being produced with a 4:3 aspect ratio are able to be seen on the HDTV display with black bars on both sides of the picture. This is because the broadcaster is sending a HDTV broadcast with a 16:9 aspect ratio with the older 4:3 picture centered within the wider HDTV display. A disadvantage of HDTV for viewing older 4:3 aspect ratio programs is that for a similar screen diagonal size (for example, a 32 inch diagonal screen), the HDTV display is literally shorter vertically when compared to a standard definition (4:3) screen. That is because the display is longer. A 32 inch 4:3 display is 19.2 inches tall whereas a 32 inch HDTV display is merely about 15.7 inches tall. This means that for a HDTV with the identical diagonal dimension as an older 4:3 aspect TV, the overall total screen area displaying an older TV program will actually be smaller. For viewing an older TV program, in order to achieve the same vertical dimension and picture size in an HDTV as from an older standard definition television you have to have a longer diagonal screen size. You would have to buy a 40 inch HDTV to deliver a tad more height than an older 32 inch standard definition screen. So, if watching older TV programs is of interest for your requirements, keep this in mind. So, now you recognize a few of the benefits of the modern HDTV standard for TV displays. At this point, it is time to settle on the size of the screen that's best for you and whether to get a Plasma screen or an LCD screen.
