D5
(Digital 5) A 1/2" broadcast-quality component digital videotape format that records uncompressed frames in the ITU-R BT.601 standard. D5 VTRs use the same cassettes as D3. Because D5 uses 1/2" media and also conforms to ITU-R BT.601, it provides a less costly version of the 19mm D1 format and is more widely used. HD D5 provides high definition video up to 1080 lines at a 5:1 compression ratio. HD D5 VTRs also support the standard definition (SD) format. See ITU-R BT.601 and D1.
