Zusammenfassung:	A digital network manages and utilizes multiple applications in consumer terminals (150), such as set-top boxes. Terminals are authorized individuall y to use one or more of a number of available applications, such as e-mail, video on demand, stock ticker, or a web browser. A download message from a headend (115) authorizes each terminal (150) to download and use specific applications by building its own "local" Virtual Application Table (VAT) (355). Different terminals can be authorized to recover and use different versions (314, 316, 318; 334, 336; 354; 374, 376, 378, 379) of the same application (312; 332; 352; 372) which, e.g., provide enhanced features over the basic application, or provide a test version for trouble-shooting or tes t marketing.
