The Digital Fact Book - Quantel

True random accessQuantel term for the ability to continuously read any frame, or sequence of frames, in anyorder at or above video (or realtime) rate, a part of FrameMagic. A true random access videostore (usually comprising disks) can allow editing which offers rather more than just quickaccess to material. Cuts are simply instructions forthe order of replay and involve no copying,so adjustments can be made as often and whenever required. This results in instant andvery flexible operation. At the same time technical concerns associated with fragmentationdo not arise as the store can operate to specification when fully fragmented, ensuring fulloperation at all times. This aspect is particularly important for server stores.See also: Consolidation, Fragmentation, FrameMagic, Simultaneous true random access,Server (video), Uncommitted editingRandom Access1 2 3 4 56 7 8 9 10 11 12 13 14 1511 12 13 14 15True Random AccessT1 2 3 4 56 7 8 9 10 2 7 13 4 811 12 13 14 15170
