DISee Digital intermediateDiagnosticsTests to check the correct operation of hardware and software. As digital systems continueto become more complex, built-in automated testing becomes an essential part of theequipment for tests during both manufacture and operation. This involves some extrahardware and software to make the tests operate. Digital systems with such provisionscan often be quickly assessed by a trained service engineer, so speeding repair.DRemote diagnostics can make use of an Internet connection to monitor and test a productat the customer’s site while working from a central service base. Thus expert attention canbe used immediately on site.Interdependent multiple systems, such as a video server and its clients, may requiresimultaneous diagnostics of all major equipment. Here, combining data links from a numberof pieces of networked equipment, as with Quantel’s R-MON, effectively extends the RemoteDiagnostics to larger and more complex situations.See also: DiagnosticsDiBEGDigital Broadcasting Experts Group, founded September 1997 to drive the growth of digitalbroadcasting and international contribution by promoting the exchange of technicalinformation and international co-operation.

If you can find it easily and have rights to useor sell it, it has value. The content will vary in size from a whole movie, to a few frames ofnews footage. Digital Asset Management (a.k.a. media asset management or digital assetwarehousing) is about the storage and use of both digital content and its metadata. The lattercomprises descriptions of the content, such as text and thumbnail images, stored in adatabase for easy searching and management.
