Broadcast and Displays
EDTV broadcasts use less digital bandwidth than HDTV, so TV stations can broadcast several EDTV stations at once. Like SDTV, EDTV signals are broadcast with non-square pixels. Since the same number of horizontal pixels are used in 4:3 and 16:9 broadcasts, the 16:9 mode is sometimes referred to as anamorphic widescreen. Most EDTV displays use square pixels, yielding a resolution of 852 × 480. However since no broadcasts use this pixel count, such displays always scale anything they show. The only sources of 852 × 480 video are Internet downloads, such as from iTunes, and some video games. Unlike 1080i and SDTV formats, plasma displays can show EDTV signals without the need to de-interlace them first. This can result in a reduction of motion artifacts.

Famous quotes containing the words broadcast and/or displays:
“Adjoining a refreshment stand ... is a small frame ice house ... with a whitewashed advertisement on its brown front stating, simply, “Ice. Glory to Jesus.” The proprietor of the establishment is a religious man who has seized the opportunity to broadcast his business and his faith at the same time.”
—For the State of New Jersey, U.S. public relief program (1935-1943)
“Adults understandably assume that the level of verbal proficiency a five-year-old displays represents his level of proficiency in all areas of functioning—if he talks like an adult, he must think and feel like one. However, five-year-olds,... belie the promise of adult-like behavior with their child-like, impulsive actions.”
—Dorothy H. Cohen (20th century)
