Which is better, EDTV or HDTV?Written by bradley james
With all new digital formats out there, it is of little surprise that there exists considerable confusion about EDTV and HDTV. First of all, EDTV stands for Enhanced Definition Television, while HDTV stands for High Definition Television. TVs equipped with either of these formats are capable of receiving and potraying images in a digital fashion - both of which are superior in visual quality to standard TV (SDTV).
Which is better, EDTV, or HDTV?
This is a question that comes up quite often, and it really has a simple answer: HDTV is better. However, EDTV wasn't really made to be a competitor for HDTV, but rather a transition technology that was better than standard, but not all way High Definition, as HDTV is. And although Enhanced Definition Television (EDTV) doesn't quite offer oustanding life-like quality attributed to High Definition Television (HDTV), its picture is actually closer to HDTV than regular television. HDTV has an impressive 720 progressive scanning (1280x720 pixels) or 1080 interlaced (1920x1090 pixels) lines. Thus, it easily meets requirement of high definition broadcasts. EDTV, on other hand, displays pictures at 480 progressive scan (640x480 pixels), which is the highest resolution available on DVD. In fact, EDTV is considered optimized for DVD format. However, this puts a severe limit on EDTV, which is simply not able to display higher resolution HD content.
