Lack of brightness has long been a shortcoming of rear—projection TV5, but large—screen Improved Definition Television (IDV) units now deliver images with greater definition and accuracy than any conventional television monitor/receiver. Conventional TV displays 262.5 scanning lines every 1/60th of a second to “paint” the image on the screen. With IDV, the scanning rate is doubled to 525 lines, improving vertical resolution by 40 percent. Special filtering overcomes the distortion often associated with earlier versions of IDV. As with any new technology, prices tend to be high at first. However, there is now an attractively priced unit on the market, the 41 inch Philips 41JP21SA at $2,999 before institutional discount. Not only does the unit deliver an image superior to any unit priced under $10,000 that we have seen, but it includes an MTS stereo tuner, six speakers, S-VHS inputs, and picture—in-picture for viewing multiple channels on the screen.
Improved Definition Television should not be confused with High Definition Television (HDTV), which involves broadcasting a higher resolution signal. Despite its promise, HDTV is caught in a tug-of-war over standards. Industry forecasts fix the widespread introduction of HDTV in the U.S. between 1996 and 1999.
