The process of converting a media file or object from one format
to another. Transcoding is often used to convert video formats (i.e., Beta to VHS, VHS to QuickTime
, QuickTime to MPEG
). But it is also used to fit HTML
files and graphics files to the unique constraints of mobile devices
and other Web-enabled products. These devices usually have smaller screen sizes, lower memory, and slower bandwidth
rates. In this scenario, transcoding is performed by a transcoding proxy server
or device, which receives the requested document or file and uses a specified annotation to adapt it to the client.
