D1

(Digital 1) A 3/4" (19mm) broadcast-quality component digital videotape format that records uncompressed frames in the ITU-R BT.601 standard. Using costly tape decks and metal-particle cassettes, D1 uses 1MB of storage for each frame and 2GB of storage per minute. At 30 fps, it requires a 27MB/sec transfer rate, as there is a small amount of compression that takes place. See ITU-R BT.601 and D5.
