1) An early 3/4" (19mm) broadcast-quality component digital videotape format that recorded uncompressed frames in the ITU-R BT.601 standard. Developed by Sony and Bosch in the mid-1980s, D-1 was the first professional digital video format, later standardized by SMPTE.
Using costly tape decks and metal-particle cassettes, D-1 recorded standard definition (SD) at 704x480 pixels. Using a small amount of compression, 30 fps required a transfer rate of 27MB per second. See
ITU-R BT.601,
D-2 and
SD formats.
