Enhanced Definition Television (EDTV) is a quality standard for digital TV that corresponds to studio quality with resolutions of 704 x 480 pixels. There is a version with a lower resolution of 640 x 480 pixels.
EDTV is standardized with different frame rates and with aspect ratios of 16:9 and 4:3. The EDTV standard was defined by the ITU-R and is the successor of D2-MAC. EDTV is available with interlaced and progressive scan as 24p, 30p, 60i and 60p, i.e. with 24 Hz, 30 Hz and 60 Hz refresh rates. Depending on the version, the number of pixels transmitted ranges from 8.1 MPixel/s to 20.3 MPixel/s. The transmission rate for EDTV is specified in the ITU BT.601 recommendation between 6 Mbps and 8 Mbps.
